How to Complete Your Sole Proprietorship Registration in Denmark

Starting a business can be an exciting, yet daunting process, especially when it comes to registering your sole proprietorship. In Denmark, the registration process for a sole proprietorship is straightforward but requires a thorough understanding of the necessary proceedings. This guide will break down the steps you need to take, from understanding the concept of a sole proprietorship to navigating the registration process and maintaining compliance with Danish regulations.

Understanding Sole Proprietorships in Denmark

A sole proprietorship (enkeltmandsvirksomhed) is a simple and common business structure in Denmark. It is suitable for individual entrepreneurs who want to run their business independently. Key characteristics of a sole proprietorship include:

- Limitation of Liability: As a sole proprietor, you are personally liable for your business activities, meaning that your personal assets can be at risk if the business incurs debts or legal problems.

- Taxation: Profits from the business are taxed as personal income, and there is no corporate tax to pay.

- Flexible Structure: You can operate your business without the formal requirements needed for larger business entities like limited liability companies.

This simplified structure makes it attractive for many small business owners or freelancers, but these advantages come with unique legal responsibilities.

Benefits of Choosing a Sole Proprietorship

Before diving into the registration process, it's essential to understand why a sole proprietorship could be the ideal choice for your business needs:

1. Ease of Setup: Registering as a sole proprietor is relatively simple and requires fewer formalities compared to other business structures in Denmark.

2. Full Control: You maintain complete control over your business decisions without the need for consensus among partners or shareholders.

3. Lower Costs: The costs associated with starting a sole proprietorship are generally lower than those for other business structures, as there are fewer regulatory requirements.

Tax Simplicity: Profits are taxed directly at the owner's income tax rate, which can streamline your financial management.

5. Flexible Profit Distribution: You can take all profits without having to distribute them in a specific manner.

Essential Requirements for Registering a Sole Proprietorship

Before starting your application to register a sole proprietorship in Denmark, ensure that you have the following:

1. Personal Identification: A valid Danish CPR (Central Person Register) number is required.

2. Business Name: You need to choose a unique name for your business that complies with Danish naming regulations.

3. Business Address: A registered address is necessary for official correspondence. This can be your home address if you are operating from there.

Steps to Complete Your Sole Proprietorship Registration

Now that you understand the basics, let's journey through the steps to register your sole proprietorship in Denmark:

Step 1: Choose a Business Name

The first step in registering your sole proprietorship is choosing a business name. The name should reflect your business activity and resonate with your target audience. Danish law prohibits the use of names that may mislead customers or are too similar to existing businesses.

- Name Check: You can verify the availability of your desired business name through the Danish Business Authority's (Erhvervsstyrelsen) online database. If your name passes the checks, you are ready for the next step.

Step 2: Prepare Required Documents

While the registration process is relatively simple, gathering the necessary documentation is critical. The main documents you typically need include:

- Identification: A copy of your CPR number.

- Proof of Address: A utility bill or official document that confirms your registered business address.

- Business Plan: While not necessarily required, having a simple business plan clarifies your strategy and helps establish your business goals.

Step 3: Register Your Business Online

With the business name and necessary documents ready, you can initiate the registration process via the Danish Business Authority's online portal:

- Access the Registration Portal: Go to the Erhvervsstyrelsen website, where you can find the registration option for sole proprietorships. You will need to create an account on the portal if you do not have one already.

- Fill out the Registration Form: Complete the online form, entering essential information such as your name, CPR number, business name, business address, and type of services or products offered.

- Pay the Registration Fee: A small registration fee is often required. Payment can typically be made directly through the online portal using a credit or debit card. The fees and payment methods may change; thus, check the latest updates on the Danish Business Authority's site.

Step 4: Await Confirmation

After submitting your application and making the necessary payment, await confirmation from the Danish Business Authority. The process of approval usually takes a few days but can vary depending on the volume of applications being processed.

- Registration Number: Upon approval, you will receive a registration number (CVR number) that identifies your business in Denmark. This number is crucial for tax purposes and legal identification.

Tax Obligations for Sole Proprietorships in Denmark

Once registered, it is necessary to understand your tax obligations as a sole proprietor in Denmark:

Income Tax

Profits generated from your business are subject to personal income tax, which is progressive in Denmark. Be prepared to file your income tax return annually, declaring all income earned through your sole proprietorship. It's essential to keep accurate financial records to help simplify this process.

Value Added Tax (VAT)

If your annual turnover exceeds DKK 50,000, you must register for VAT. As a VAT-registered business, you will need to charge VAT on your sales and file VAT returns. It's crucial to keep track of VAT to ensure compliance and avoid penalties.

Business Expenses Deductions

As a sole proprietor, you can deduct business-related expenses from your income, which can reduce your taxable profit. Common deductible expenses may include:

- Office supplies

- Travel expenses related to business

- Marketing costs

- Professional services fees (e.g., accounting, legal consultations)

Keep thorough records of all business transactions to substantiate your deductions.

Maintaining Your Sole Proprietorship

Once you've completed your registration and begun running your business, it's vital to maintain your operational compliance. Consider the following:

Regular Accounting Practices

Effective accounting is crucial for the longevity of your sole proprietorship. Maintaining accurate financial records helps in tax filing and financial analysis:

- Bookkeeping: Regularly update your books with all transactions. This will help you understand your business's financial health and prepare for your annual tax return.

- Hiring an Accountant: Depending on the size and complexity of your business, it may be beneficial to hire a professional accountant to manage your finances and ensure compliance.

Filing Taxes and VAT Returns

Timely filing of your income tax and VAT returns is crucial. Failure to do so can lead to penalties. Mark relevant deadlines on your calendar to avoid missing them.

- Annual Tax Return: File your personal income tax return by the specified deadline each year.

- Quarterly VAT Returns: If registered for VAT, submit returns every three months to report the VAT collected and remitted.

Licenses and Permits

While a sole proprietorship does not require extensive licenses, specific businesses may need local permits or specialized licenses (e.g., food service, construction). Always check local regulations and obtain any necessary licenses before commencing operations.

Closing Your Sole Proprietorship

Should you decide to cease operations, it's important to know the proper procedure for closing your sole proprietorship in Denmark:

1. Notify Employees: If you have employees, they must be informed about the closure and any required severance packages.

2. Settle Business Debts: Pay off any outstanding obligations before formally closing the business.

3. File Final Tax Returns: Make sure to file your last income tax and VAT returns.

Deletion Request: You can submit a request for deletion of your business from the Danish Business Authority's register online.

Legal Differences Between a Sole Proprietorship and Other Business Forms in Denmark

A sole proprietorship (enkeltmandsvirksomhed) is the simplest way to run a business in Denmark, but it is legally very different from other common business forms such as an ApS (private limited company), IVS (now phased out), I/S (general partnership) or A/S (public limited company). Understanding these differences helps you choose the right structure for your activity, risk profile and tax situation.

Liability and personal risk

The most important legal difference concerns liability. In a sole proprietorship, there is no separation between you and your business. You are personally liable for all business obligations with your entire private wealth, including your home, car and savings. If the business cannot pay its debts, creditors can pursue your personal assets.

In contrast, an ApS and A/S are separate legal entities. Owners’ liability is generally limited to the capital they have invested in the company. For an ApS, the minimum share capital is 40,000 DKK, which can be paid in cash or as contributed assets. If the company goes bankrupt, your personal assets are normally protected, provided you have not given personal guarantees or acted negligently or fraudulently.

An I/S (interessentskab) sits in between: it is not a separate legal entity like an ApS, and each partner is personally and jointly liable for all partnership obligations. This means that if your partner cannot pay, creditors can claim the full amount from you.

Legal personality and contracts

A sole proprietorship does not have its own legal personality. Legally, you and the business are the same person. You sign contracts in your own name, and you are the direct party to all agreements with customers, suppliers, landlords and banks.

Companies such as ApS and A/S are independent legal persons. The company signs contracts in its own name, can own assets, incur debts and be sued or sue others. As an owner or director, you act on behalf of the company, but you are not personally a party to every contract.

Registration and capital requirements

Registering a sole proprietorship with the Danish Business Authority (Erhvervsstyrelsen) is free of charge and does not require any minimum capital. You can register online via Virk using your MitID and obtain a CVR number for your business.

By comparison, an ApS must be established with at least 40,000 DKK in share capital and must have formal incorporation documents, articles of association and, in many cases, assistance from a lawyer or accountant. There are also registration fees and stricter documentation requirements.

Taxation of profits

For a sole proprietorship, business profit is taxed as your personal income. You report it on your personal tax return (årsopgørelse) and pay:

• Labour market contribution (AM-bidrag) of 8% on your business income before personal income tax
• Bottom tax (bundskat) of 12.09% on personal income above the personal allowance
• Top tax (topskat) of 15% on personal income above the top tax threshold (around 588,900 DKK after AM-bidrag)

On top of this, you pay municipal and church tax depending on where you live. The total marginal tax rate on business profit can therefore reach around 52–56% for high incomes.

You can choose the business tax scheme (virksomhedsordningen) or capital return scheme (kapitalafkastordningen) to optimize taxation, for example by retaining profits in the business at a lower provisional tax rate and deducting interest more favourably. However, the profit is always ultimately taxed as your personal income.

In an ApS or A/S, the company pays corporate tax (selskabsskat) on its profits. The corporate tax rate is 22%. When you withdraw money as salary, it is taxed as personal income. When you withdraw money as dividends, it is taxed as share income (aktieindkomst) at 27% up to the lower threshold and 42% above it. This creates a two‑level tax structure that can be more flexible for higher and fluctuating incomes.

Accounting, reporting and audits

Sole proprietors must keep proper bookkeeping and retain documentation for at least five years, but the formal reporting requirements are lighter than for companies. If your sole proprietorship is not registered as a limited liability entity (for example, as an “enkeltmandsvirksomhed med begrænset ansvar” – which is rare), you normally do not have to file annual financial statements with the Danish Business Authority. You report your results directly to the Danish Tax Agency (Skattestyrelsen) through your tax return.

ApS and A/S companies must prepare annual financial statements in accordance with the Danish Financial Statements Act (årsregnskabsloven) and submit them to the Danish Business Authority. Depending on the company size, they may also be subject to mandatory audit or extended review by a state‑authorized or registered public accountant. This increases administrative costs but also provides more transparency and credibility towards banks and business partners.

Management and ownership structure

In a sole proprietorship, you are the only owner and have full control over all decisions. There is no legal requirement to appoint a board of directors or management body. You can employ staff, but they do not become co‑owners unless you change the business form.

In an ApS or A/S, ownership is divided into shares. The company must have at least one founder and one director. An A/S must also have a board of directors or supervisory board. Decisions are made through formal bodies such as the general meeting and board meetings, and there are specific rules on shareholder rights, voting and documentation.

Raising capital and attracting investors

A sole proprietorship cannot issue shares or ownership interests. If you want to bring in investors, you must usually convert the business into an ApS or another company form. Banks often require personal guarantees from sole proprietors, and financing is closely tied to your private financial situation and creditworthiness.

Companies like ApS and A/S can issue shares, attract investors and structure ownership with different share classes. This makes it easier to raise capital for growth, bring in partners and plan succession. Investors usually prefer limited liability structures because their risk is limited to the amount invested.

Continuity and transfer of the business

A sole proprietorship is legally tied to you as a person. It cannot continue in its existing legal form if you die or permanently stop your activity. The business assets can be sold or transferred, but the legal identity of the business ends with you. This can complicate succession planning and sale of the business.

An ApS or A/S continues to exist regardless of changes in ownership or management. Shares can be sold, gifted or inherited, and the company can continue operating without interruption. This makes it easier to sell the business, bring in new owners or plan generational change.

Regulatory obligations and compliance

Both sole proprietorships and companies must comply with Danish rules on VAT (moms), A‑tax and AM‑bidrag for employees, bookkeeping, invoicing and data protection (GDPR). However, companies are subject to additional corporate law requirements, such as rules on capital protection, loans to shareholders, distributions, and formal decision‑making procedures.

Sole proprietors have more flexibility in how they manage their business day to day, but they must still comply with sector‑specific regulations, licensing rules and consumer protection laws relevant to their activity.

When a sole proprietorship is typically chosen

A sole proprietorship is often the best choice when you:

• Start a small business with limited financial risk
• Expect modest or moderate profits in the first years
• Want simple administration and low start‑up costs
• Do not need external investors or complex ownership structures

If your business grows, your risk increases or you plan to bring in partners or investors, converting your sole proprietorship into an ApS can provide better protection, more tax planning options and a more professional framework for further development.

Choosing the Right Business Name and Checking Name Availability

Choosing the right name for your sole proprietorship in Denmark is more than a branding decision – it also has legal and practical implications. A clear, distinctive name helps customers find you, builds trust and reduces the risk of conflicts with other businesses.

Business name vs. personal name

As a sole proprietor (enkeltmandsvirksomhed), you can operate under your own personal name, for example “Anna Jensen”. In practice, most owners choose a business name (virksomhedsnavn) that reflects their services, such as “Anna Jensen Consulting” or “Copenhagen Bike Repair”.

Your registered business name will appear in the Danish Business Register (CVR) and on invoices, contracts and official correspondence. You can also register one or more secondary names (binavne) if you run different activities under the same CVR number.

Legal rules for Danish business names

When you register your sole proprietorship with the Danish Business Authority (Erhvervsstyrelsen), your chosen name must comply with Danish naming rules. In general, the name must:

• Clearly identify your business and not be misleading about what you do
• Be distinguishable from existing registered business names
• Use Latin letters (A–Z), Danish letters (Æ, Ø, Å) and standard punctuation only
• Not contain protected titles or words that you are not legally entitled to use (for example “bank”, “forsikring” (insurance) or “advokat” (lawyer) without the required licence)
• Not be offensive, discriminatory or contrary to public order

A sole proprietorship cannot use endings that suggest another legal form, such as “ApS”, “A/S”, “IVS” or “P/S”. If you choose a foreign-language name, it must still comply with Danish rules and not mislead customers about your legal structure or authorisations.

Checking name availability in the CVR register

Before you decide on a name, you should check whether it is already in use. The primary tool is the Central Business Register (CVR), where all registered Danish businesses are listed. You can:

• Search by name to see if an identical or very similar name is already registered
• Check whether the name is used in your industry or geographic area
• Review how competitors in your field name their businesses

If a name is already registered and considered confusingly similar to your proposal, the Danish Business Authority can refuse your registration or ask you to change the name. Even if a similar name exists in a different sector, it is wise to choose something more distinctive to avoid mix-ups and potential disputes.

Considering trademarks and domain names

Registering a business name in CVR does not automatically give you trademark protection. Another company may already hold a registered trademark (varemærke) for the same or a similar name, logo or slogan. To reduce legal risk, you should:

• Search the Danish Patent and Trademark Office database for identical or similar trademarks
• Check EU and international trademark databases if you plan to sell outside Denmark
• Assess whether your name could be confused with an existing protected brand in the same line of business

It is also practical to secure a matching internet domain. Check the availability of .dk domains through an accredited registrar and consider registering relevant variations (for example .dk and .com) to protect your online presence.

Practical tips for choosing a strong business name

Beyond legal compliance, your name should support your marketing and make it easy for customers to remember and find you. When brainstorming names, consider whether it is:

• Easy to pronounce and spell in Danish (and English if you target international clients)
• Descriptive enough to indicate your service or niche
• Short enough to fit comfortably on invoices, websites and social media profiles
• Unique in search engines so that your business appears at the top of results

If you expect to expand your services or target group, avoid names that are too narrow or tied to a specific location, unless local branding is part of your strategy.

Registering and changing your business name

You formally register your chosen name when you create your sole proprietorship through the Danish Business Authority’s online self-service. The name you enter there becomes your official business name in CVR once your registration is approved.

If you later decide to change your name, you can update it via the same online system. The new name must also comply with all naming rules and will replace the old name in the register. Remember to update your invoices, website, contracts, signage and any marketing materials to reflect the change, so customers and authorities can clearly identify your business.

Registering for VAT (Moms) and When It Becomes Mandatory

In Denmark, VAT (moms) is a consumption tax that most businesses must charge on the goods and services they sell. As a sole proprietor, you are responsible for assessing whether you must register for VAT, registering on time and reporting VAT correctly to the Danish Tax Agency (Skattestyrelsen). Failing to register when required can lead to backdated VAT claims, interest and penalties.

When VAT Registration Becomes Mandatory

You must register your sole proprietorship for VAT when your VAT‑liable turnover exceeds, or is expected to exceed, DKK 50,000 within any 12‑month period. This is not tied to the calendar year; you must look at a rolling 12‑month period.

You are required to register if:

• Your actual turnover has already passed DKK 50,000 in the last 12 months, or
• You reasonably expect to exceed DKK 50,000 in the coming 12 months based on contracts, orders or a realistic business plan.

The threshold applies to the total taxable turnover of your sole proprietorship, not per product line or per customer. If you operate several activities under the same CPR/CVR as one sole proprietorship, you must add all taxable sales together.

Who Must Register for VAT

In most cases, you must register if you:

• Sell goods or services in Denmark as a business activity on a regular basis
• Charge for your work (consulting, design, IT services, trades, wellness, etc.)
• Sell digital services, subscriptions or online courses to Danish customers

Some activities are exempt from VAT under Danish law, for example many healthcare services, certain financial services, insurance and some educational services. If your activity is fully VAT‑exempt, you normally cannot register for VAT and you do not charge VAT on your invoices, but you also cannot deduct input VAT on your purchases.

If you sell both VAT‑liable and VAT‑exempt services, you may have partial VAT liability, and only part of your input VAT will be deductible. In such cases, it is important to set up your bookkeeping correctly from the start.

Voluntary VAT Registration Below the Threshold

You may choose to register for VAT even if your turnover is below DKK 50,000. Voluntary registration can be beneficial if:

• You have significant start‑up costs with VAT (equipment, software, rent, subcontractors)
• Your customers are mainly VAT‑registered businesses that can deduct the VAT you charge

By registering voluntarily, you can deduct input VAT on your business purchases, but you must also charge VAT on your sales and submit VAT returns from the date of registration.

Standard VAT Rate and Special Schemes

The standard VAT rate in Denmark is 25% on most goods and services. There are no reduced VAT rates for specific sectors such as food or hospitality, but some supplies are zero‑rated or exempt according to specific rules.

Depending on your activity, you may fall under special VAT schemes, for example for travel agencies, used goods or margin schemes. Most typical sole proprietors (consultants, freelancers, tradespeople, online service providers) use the standard VAT rules.

How to Register Your Sole Proprietorship for VAT

You register for VAT via the Danish Business Authority’s online self‑service, which you access with your NemID/MitID. In practice, VAT registration is usually done when you create your sole proprietorship, but you can also add VAT registration later if your situation changes.

During registration you must:

• Indicate the date from which your business becomes VAT‑liable
• Describe your main business activity (industry code/branchekode)
• Estimate your expected annual turnover

Once the registration is approved, your business will receive a CVR number (if you do not already have one), and you will be able to log in to Skat’s online system (TastSelv Erhverv) to manage your VAT.

VAT Reporting Periods and Deadlines

Your VAT reporting frequency depends on your turnover:

• Turnover up to DKK 5 million per year: VAT is usually reported semi‑annually
• Turnover between DKK 5 million and DKK 50 million per year: VAT is usually reported quarterly
• Turnover above DKK 50 million per year: VAT is usually reported monthly

Most new sole proprietors start with semi‑annual or quarterly reporting. The exact deadlines for each period are set by Skattestyrelsen and are visible in your TastSelv Erhverv account. You must submit your VAT return and pay any VAT due by the deadline, even if you have had no activity (in which case you report zero).

What You Must Charge and Report

Once registered, you must:

• Charge 25% VAT on all VAT‑liable sales in Denmark from your VAT start date
• Issue invoices that clearly show the VAT amount and your CVR number
• Keep proper bookkeeping records of all sales and purchases
• Report output VAT (VAT on your sales) and input VAT (VAT on your purchases) in your VAT return

The VAT you pay to Skattestyrelsen is the difference between your output VAT and input VAT. If your input VAT exceeds your output VAT in a period, you can usually get a refund.

Cross‑Border Sales and VAT

If you sell to customers in other EU countries or outside the EU, special VAT rules may apply, especially for:

• Digital services to private consumers in other EU countries
• Goods shipped across borders
• Services to foreign businesses (B2B)

In some cases you may need to use the One Stop Shop (OSS) scheme or apply reverse charge rules. It is important to clarify your VAT obligations before you start selling internationally.

Consequences of Late or Missing VAT Registration

If you should have been registered for VAT but failed to do so, Skattestyrelsen can require you to:

• Register retroactively from the date your business became VAT‑liable
• Pay VAT on your past sales, even if you did not charge VAT to your customers
• Pay interest and possible penalties for late payment and incorrect reporting

To avoid problems, monitor your turnover regularly and register as soon as you see that you will exceed the DKK 50,000 threshold or decide to register voluntarily. If you realise you should have registered earlier, it is usually better to contact Skattestyrelsen or your accountant proactively and correct the situation.

NemID/MitID and Accessing Online Self-Service for Business Registration

To register a sole proprietorship in Denmark, you need secure digital identification and access to online self-service platforms. Today, NemID is being fully replaced by MitID, and most business-related services are already available only with MitID. Understanding how MitID works and how to use it on Virk.dk and skat.dk will make your registration process faster and more secure.

From NemID to MitID – what you actually need now

NemID was the previous digital ID used in Denmark for both private and business purposes. It is being phased out and replaced by MitID, which is now the standard solution for logging in to public services, including business registration and tax.

If you are starting a sole proprietorship now, you should focus on obtaining MitID. In practice, you will use:

• MitID (private) – linked to your CPR number, used to log in to most public self-service solutions
• MitID Erhverv – used when you need to act on behalf of your business (for example, to grant access to an accountant or employee)

For a simple one-person business, you can usually start and complete the registration using only your personal MitID. MitID Erhverv becomes relevant once your company is registered and you need to manage roles and access for others.

Prerequisites before you start the online registration

Before you log in to register your sole proprietorship, make sure you have:

• A valid CPR number and Danish address
• Active MitID (app or physical code solution)
• Basic information about your business: trade name, business address, expected start date and a short description of your activity
• An estimate of your expected annual turnover, to decide whether you should register for VAT (mandatory when your taxable turnover exceeds DKK 50,000 over a 12‑month period)

If you do not yet have MitID, you must obtain it before you can complete the online registration. This is usually done through your bank or at a Borgerservice center, depending on your situation.

Accessing online self-service on Virk.dk

The central portal for business registration in Denmark is Virk.dk, operated by the Danish Business Authority (Erhvervsstyrelsen). This is where you register your sole proprietorship and obtain a CVR number.

The typical process is:

1. Go to Virk.dk and choose the self-service solution for starting a sole proprietorship (enkeltmandsvirksomhed)
2. Log in with your MitID
3. Fill in the online form with your personal and business details
4. Indicate whether you want to register for VAT and/or as an employer
5. Submit the registration and download or save the confirmation

In most cases, your CVR number is issued shortly after you submit the form. You will then be able to see your business information in the Central Business Register (CVR) and use your CVR number on invoices and contracts.

Using MitID on skat.dk for tax and VAT

Once your sole proprietorship is registered, you will manage your tax and VAT obligations through skat.dk and the TastSelv self-service system. You log in with the same MitID you used on Virk.dk.

Through skat.dk you can:

• Register or adjust your VAT registration if your turnover changes
• Report VAT (moms) for each VAT period
• Report A‑tax and AM‑bidrag if you have employees
• Report B‑income and business income in your annual tax return
• Update preliminary income assessment (forskudsopgørelse) to reflect your business income

Timely access to skat.dk with MitID is crucial, as VAT and tax deadlines are strict, and late reporting can result in interest and penalties.

MitID Erhverv – acting on behalf of your business

After your sole proprietorship is registered and has a CVR number, you can set up MitID Erhverv if you need to:

• Give your accountant or bookkeeper access to Virk.dk and skat.dk on behalf of your business
• Allow employees to handle payroll, VAT reporting or other administrative tasks
• Use digital post (Digital Post) and other business-related public services under the company identity

MitID Erhverv lets you define roles and rights, so each person only has access to the functions they need. This is particularly important for data protection and internal control.

Typical issues and how to avoid them

Many new sole proprietors experience delays because of problems with digital access. The most common issues are:

• Trying to register a business before MitID is fully activated
• Using outdated NemID credentials that no longer work for business services
• Not having the correct rights set up in MitID Erhverv for an external accountant or assistant

To avoid these problems, activate your MitID in advance, verify that you can log in to both Virk.dk and skat.dk, and, if you work with an accountant, agree on who will handle which registrations and ensure they have the necessary digital access.

With a functioning MitID and access to the main self-service portals, the entire registration of your Danish sole proprietorship can be completed online, without paper forms or physical visits. This digital setup also makes it easier to stay compliant with reporting and payment obligations as your business grows.

Registering as an Employer and Handling Employee Obligations

When your Danish sole proprietorship starts hiring staff, you must register as an employer and follow specific employee-related obligations. Failing to do so can lead to fines, interest and problems with SKAT (the Danish Tax Agency) and other authorities, so it is important to set things up correctly from the start.

When you must register as an employer

You must register as an employer as soon as you pay salary or other taxable remuneration to another person for work performed for your business. This includes full-time and part-time employees, student workers, temporary staff and, in many cases, family members working in the business.

If you only buy services from independent contractors who are genuinely self-employed, you normally do not register as an employer. However, Danish rules on whether a person is an employee or self-employed are strict, and misclassification can be costly. If the person works mainly for you, follows your instructions, uses your tools and has limited financial risk, the authorities are likely to treat them as an employee.

How to register as an employer

You register as an employer through the Danish Business Authority’s online self-service (Virk) using your MitID. In most cases, you update your existing sole proprietorship registration by adding “employer” as an activity. After registration, SKAT will create the necessary employer accounts for A-tax and AM-bidrag and you will be able to report payroll via eIndkomst.

Make sure that:

• your business CVR number is active and correctly registered as a sole proprietorship
• you have access to TastSelv Erhverv for tax reporting
• you have chosen a payroll solution that can report to eIndkomst

Key employer obligations in Denmark

As an employer, you are responsible for correctly withholding and paying employee taxes and contributions, complying with employment law and reporting to the relevant authorities. The main obligations include:

Withholding A-tax and AM-bidrag

For each employee, you must withhold:

• A-tax (income tax on salary) according to the employee’s tax card (skattekort). The tax rate depends on the employee’s personal tax situation, including their personal allowance and municipality tax rate.
• AM-bidrag (labour market contribution) at a flat rate of 8% of the gross salary before A-tax.

You must obtain the employee’s electronic tax card from SKAT via your payroll system before paying the first salary. If you do not have a valid tax card, you must withhold A-tax at a high standard rate on top of the 8% AM-bidrag.

Reporting salary via eIndkomst

All salary payments must be reported digitally to SKAT’s eIndkomst system. This is usually done automatically through your payroll software. For most small employers, reporting is done monthly, and you must respect the deadlines set by SKAT for both reporting and payment.

In practice this means that:

• you report the total salary, AM-bidrag and A-tax for each employee for the period
• you pay the withheld A-tax and AM-bidrag to SKAT by the statutory due date
• you keep documentation for all calculations and payments

Holiday pay and the Danish Holiday Act

Employees in Denmark earn 2.08 days of paid holiday for each month of employment, which equals 25 days per year for full-time employees. Under the current concurrent holiday system, employees earn and can take holiday in the same period.

Depending on your setup, you either:

• pay ongoing holiday pay together with salary (for example, for hourly paid workers), or
• accrue holiday pay and manage it via FerieKonto or a recognised holiday fund.

You must state clearly in the employment contract how holiday pay is handled and ensure that all holiday earnings and payments are reported correctly.

ATP and other statutory contributions

Most employees must be enrolled in ATP Livslang Pension (the Danish labour market supplementary pension). The contribution is shared between employer and employee, and the exact amount depends on the employee’s working hours. You withhold the employee’s share from salary and pay both parts to ATP.

In some sectors, collective agreements (overenskomster) may also require you to pay into additional pension schemes, education funds or other schemes. Even if you are not a member of an employers’ organisation, you may still be bound by a collective agreement if you have signed one or if it is incorporated into your employment contracts.

Labour market insurance and work environment

Employers in Denmark must take out statutory industrial injury insurance (arbejdsskadeforsikring) for their employees. This insurance covers work-related accidents and occupational diseases. You must also register with Arbejdsmarkedets Erhvervssikring (AES) and pay the mandatory contributions.

In addition, you are responsible for providing a safe and healthy work environment in line with the Danish Working Environment Act. This includes risk assessments, proper equipment, training and, where relevant, cooperation with a health and safety representative.

Employment contracts and minimum requirements

Employees who work on average at least 3 hours per week over a reference period are entitled to a written employment contract with key terms. The contract must include at least:

• identity of employer and employee
• place of work and job title or job description
• start date and, if applicable, end date for fixed-term contracts
• working hours and schedule
• salary, bonuses, benefits and payment dates
• holiday rights and holiday pay conditions
• notice periods and termination rules
• reference to any applicable collective agreement

Clear contracts reduce the risk of disputes and make it easier to demonstrate compliance during inspections or audits.

Handling sick leave and maternity/paternity leave

You must follow Danish rules on sick pay and family-related leave. For shorter sickness periods, you may pay salary according to the employment contract or collective agreement, and you may be entitled to reimbursement of sickness benefits from the municipality after a waiting period if conditions are met.

Employees are entitled to maternity, paternity and parental leave with public benefits. As an employer, you must handle notifications, documentation and applications for reimbursement through the relevant digital systems. Many employers also top up public benefits with additional salary according to contract or collective agreement.

Data protection and employee information

When you process employee data for payroll and HR purposes, you must comply with GDPR. This means you must:

• collect only the data you need for legal and contractual purposes
• store data securely and restrict access
• inform employees about how their data is used and for how long it is stored
• have data processing agreements in place with payroll providers and other external processors

Practical tips for sole proprietors hiring staff

To handle your employer obligations efficiently:

• choose payroll software that supports Danish rules, eIndkomst reporting and ATP handling
• set up internal routines for collecting time sheets, approving hours and checking payslips
• keep all contracts, payslips, tax reports and correspondence with authorities well organised
• review regularly whether your use of freelancers is correctly classified under Danish rules

If you are unsure about any aspect of employer registration or employee obligations, consider getting professional accounting and payroll support. This helps you stay compliant, avoid penalties and free up time to focus on growing your sole proprietorship.

Social Security and Pension Considerations for Sole Proprietors

When you run a sole proprietorship in Denmark, you are not automatically covered by the same social security and pension schemes as an employee. Understanding how ATP, social benefits and private pension savings work is essential to protect your income, your family and your retirement.

Public social security for sole proprietors

As a sole proprietor, you are generally covered by the Danish welfare system on almost the same terms as employees, because you pay tax and labour market contributions (AM-bidrag) on your business income. This gives you access to:

• Public healthcare
• State pension (folkepension) when you reach the statutory pension age
• Child benefits (børne- og ungeydelse), if you have children
• Certain social benefits if your income is low and you meet the conditions

However, there are important differences when it comes to ATP, unemployment insurance and compensation during illness and maternity/paternity leave.

ATP and other statutory schemes

ATP Livslang Pension is normally paid by both employer and employee. As a sole proprietor you are not automatically enrolled through your business, because you do not have an employer. You may be covered if you also have a job as an employee alongside your business. If you only have self-employed income, you should consider:

• Voluntary ATP contributions as a self-employed person, if you meet ATP’s conditions
• Building your own pension savings to supplement the state pension

In addition, you pay 8% labour market contribution (AM-bidrag) on your business profit before income tax. This contribution helps finance the Danish welfare system but does not in itself create a personal pension pot for you.

Unemployment insurance (A‑kasse) for the self-employed

Unemployment insurance in Denmark is voluntary and handled by A‑kasser. As a sole proprietor you are not automatically insured against loss of income if your business fails. To secure unemployment benefits (dagpenge), you can:

• Join an A‑kasse that accepts self-employed members
• Pay monthly contributions like an employee
• Meet the income and membership requirements to qualify for benefits

To obtain full unemployment benefit rights as self-employed, you typically need to:

• Be a member of an A‑kasse for at least 1 year
• Have had a certain minimum income from work (employment or self-employment) within the last 3 years, with at least part of it from Denmark
• Be able to document that your business is closed or significantly reduced if you claim benefits as unemployed

The maximum unemployment benefit rate is adjusted regularly and is capped per month and per year. You will not receive compensation for 100% of your previous income, so it is important to plan for a financial buffer in addition to A‑kasse membership.

Sickness and maternity/paternity benefits

As a self-employed person you are not entitled to employer-paid salary during sickness or parental leave, but you may be entitled to public benefits if you meet the conditions.

Sickness benefits (sygedagpenge)

If you become unable to work due to illness, you may be entitled to sickness benefits from your municipality. The rules depend on how long you have run your business and your income level. In general, you must:

• Have been self-employed for a minimum period before the first day of sickness
• Have worked a minimum number of hours in your business
• Have had a certain minimum income from the business

As a sole proprietor you can take out voluntary insurance with Udbetaling Danmark to get sickness benefits from an earlier date and at a higher rate. Without voluntary insurance, there is a waiting period before you can receive benefits, and the benefit amount is limited by your documented income.

Maternity and paternity benefits (barselsdagpenge)

Self-employed parents can receive maternity and paternity benefits on similar terms to employees, but you must:

• Have been self-employed for a minimum period before the start of the leave
• Be able to document your income from the business
• Reduce or stop your work in the business during the leave period

You can also take out voluntary insurance to improve your coverage during maternity/paternity leave, for example to secure a higher benefit rate. Planning ahead is crucial, especially if your business depends heavily on your personal work effort.

State pension and supplementary public pensions

All residents in Denmark who meet the residence requirements are entitled to the state pension (folkepension) from the statutory pension age. The amount depends on your residence period in Denmark and your other income and assets.

In addition to the basic state pension, you may receive supplementary public pensions such as:

• ATP Lifelong Pension, if you have contributed as an employee or voluntarily
• Supplementary pension benefits (ældrecheck and pension supplements), depending on your financial situation

Because the state pension is relatively modest compared to a full-time salary, most sole proprietors need additional private pension savings to maintain their standard of living after retirement.

Private pension options for sole proprietors

As a sole proprietor you are responsible for building your own pension. You can use the same pension products as employees, but you pay contributions directly instead of through an employer. The most common options are:

• Rate pension (ratepension) – paid out in instalments over a fixed period, typically 10–30 years
• Life-long annuity (livrente) – paid out for the rest of your life
• Old-age savings (aldersopsparing) – paid out as a lump sum or in flexible instalments

There are annual tax-deductible limits for pension contributions. For example, rate pension contributions are deductible up to a fixed maximum per year, while life-long annuity contributions can have higher or no practical upper limits for tax deduction, subject to general tax rules. Old-age savings have their own annual deposit cap but no deduction; instead, payouts are tax-free.

Pension contributions are usually deducted in your personal tax return and reduce your taxable income, which can lower your marginal tax rate. The exact tax effect depends on your total income, including your business profit.

Insurance products linked to social security and pension

To supplement public schemes and pension savings, many sole proprietors in Denmark choose additional insurance products, such as:

• Loss of earning capacity insurance (erhvervsevnetabsforsikring) – provides income if you lose your ability to work due to illness or accident
• Critical illness insurance (kritisk sygdom) – pays a lump sum upon diagnosis of certain serious diseases
• Life insurance (livsforsikring) – secures your family financially if you die

These products can be purchased through pension companies, banks or insurance providers and can often be combined with your pension scheme. Premiums may be tax-deductible depending on the type of insurance and how it is structured.

Practical tips for planning your social security and pension

When you start or run a sole proprietorship in Denmark, it is wise to:

• Map your current coverage: state pension, ATP, any previous employer pensions and existing insurance policies
• Decide whether to join an A‑kasse that covers self-employed and consider voluntary unemployment insurance options
• Consider voluntary insurance for sickness and maternity/paternity benefits if your income depends mainly on your own work
• Set a fixed percentage of your annual profit for pension contributions and adjust it as your business grows
• Review your pension and insurance setup regularly with a professional adviser, especially when your income changes significantly

A well-planned combination of public benefits, private pension savings and insurance will give you greater financial security and flexibility as a sole proprietor in Denmark, both during your working life and in retirement.

Bookkeeping Standards and Record-Keeping Requirements in Denmark

Running a sole proprietorship in Denmark means you must follow specific bookkeeping and record‑keeping rules set by the Danish Tax Agency (Skattestyrelsen). Proper accounts are not only a legal obligation, but also the basis for correct tax, VAT and social contributions, and they significantly reduce the risk of audits, penalties and cash‑flow problems.

Who must keep accounts and in what form?

All sole proprietors with business activity in Denmark must keep orderly accounts, regardless of turnover. If you are VAT registered or have employees, the expectations for structure and documentation are higher, but even small freelancers must be able to document income and expenses.

You may keep your books digitally or on paper, but in practice digital bookkeeping is strongly recommended. Accounting records must be reliable, complete, traceable and stored in a way that prevents later manipulation. If you use accounting software, it should allow you to export data and documentation in a readable format for Skattestyrelsen.

Basic bookkeeping principles

Danish bookkeeping rules are based on a few core principles that also apply to sole proprietors:

• Ongoing registration – transactions must be recorded on a continuous basis, not only once a year. For VAT‑registered businesses, bookkeeping should at least follow your VAT periods (typically quarterly or half‑yearly).
• Completeness – all business income and expenses must be recorded, including small cash payments and private use of business assets.
• Accuracy – entries must reflect the actual transaction: correct amount, date, counterparty and description.
• Traceability – every entry must be linked to underlying documentation (invoice, receipt, contract, bank statement, mileage log, etc.).
• Separation of private and business – private and business finances must be clearly separated in your records, ideally with a dedicated business bank account.

What documents must you keep?

As a sole proprietor you must keep all documentation that supports the figures in your tax return and VAT returns. This typically includes:

• Sales invoices and credit notes issued to customers
• Purchase invoices and receipts for business expenses
• Bank statements for all accounts used in the business
• Loan agreements and interest statements
• Leases for office, warehouse or equipment
• Contracts with customers and suppliers, if relevant for revenue recognition or deductions
• Payroll records if you have employees (salary slips, holiday pay, pension contributions, A‑tax and AM‑bidrag filings)
• Asset documentation for fixed assets (invoices, depreciation schedules, sale documents)
• Vehicle logs if you deduct mileage or business use of a private car
• Inventory lists if you hold stock at year‑end

For VAT‑registered businesses, documentation must also clearly show Danish VAT (moms) amounts, VAT rates applied and whether the transaction is subject to, exempt from or outside the scope of Danish VAT (for example intra‑EU supplies).

Retention periods and deadlines

In Denmark, business records must generally be kept for at least 5 full years after the end of the financial year they relate to. This applies to both digital and paper documents. For example, records for the financial year ending 31 December must be kept for 5 subsequent calendar years.

Some specific documents, such as payroll information and documentation related to employees’ holiday pay and pension contributions, may need to be kept longer to comply with labour and social legislation. If you are unsure, it is safer to keep records for at least 5–10 years.

Structure of your bookkeeping

Even though many sole proprietors are not required to prepare a full statutory annual report, Skattestyrelsen expects a clear and logical structure in your accounts. A typical setup includes:

• A chart of accounts with separate accounts for different types of income and expenses
• Separate accounts for VAT, A‑tax and AM‑bidrag (if you have employees), and B‑income if relevant
• Clear distinction between operating expenses, investments (fixed assets) and private drawings
• Year‑end procedures for reconciling bank accounts, VAT, customer and supplier balances

At year‑end, you should be able to produce at least a profit and loss statement and a balance overview that support the figures you report in your tax return (årsopgørelse/udvidet selvangivelse) and VAT returns.

Digital bookkeeping and e‑invoicing

Most Danish sole proprietors use digital accounting systems that support Danish VAT rules, standard chart of accounts and integration with online banking. When choosing software, check that it:

• Handles Danish VAT rates correctly (standard 25% and any relevant exemptions)
• Supports periodic VAT reporting to Skattestyrelsen
• Allows you to attach digital copies of receipts and invoices to each entry
• Can export data for your accountant or for a tax audit

If you sell to public authorities, you must issue electronic invoices (e‑faktura) via the NemHandel infrastructure and use the official formats and identifiers (such as EAN/GLN numbers). Your bookkeeping must still store a readable version of each e‑invoice and link it to the corresponding accounting entry.

Cash, private use and mixed expenses

Cash transactions are allowed but must be documented carefully. You should keep a cash book that records all cash inflows and outflows and reconcile it regularly with physical cash on hand.

For assets and expenses used both privately and in the business (for example a home office, telephone, internet or car), you must document how you split the costs. The chosen method (percentage split, mileage log, square‑metre calculation for home office) must be reasonable and consistently applied, and the calculation should be documented in your records.

Bookkeeping for VAT‑registered sole proprietors

If you are registered for VAT, your bookkeeping must allow you to calculate output VAT on sales and input VAT on purchases for each VAT period. You must be able to show:

• Total VAT‑liable sales and the VAT charged
• Total VAT‑deductible purchases and the VAT you claim back
• Any VAT‑exempt or zero‑rated sales and purchases
• Adjustments, credit notes and corrections

All VAT figures reported to Skattestyrelsen must be directly reconcilable with your accounting records and underlying documentation. Errors discovered later should be corrected through your bookkeeping and, if necessary, by submitting corrected VAT returns.

Consequences of poor bookkeeping

If your bookkeeping is incomplete or unreliable, Skattestyrelsen can estimate your income and VAT based on available information, often resulting in higher tax and VAT assessments. You may also face interest, surcharges and, in serious cases, fines. Good bookkeeping significantly reduces these risks and makes it easier to respond to any questions or audits.

When to involve a professional accountant

While many Danish sole proprietors handle day‑to‑day bookkeeping themselves, professional support is often valuable when:

• You register for VAT or as an employer for the first time
• Your turnover grows and transactions become more complex
• You invest in assets, hire employees or start trading across borders
• You need to optimise deductions and ensure compliance with changing rules

An accountant familiar with Danish rules can help you set up a compliant bookkeeping system, choose suitable software and ensure that your records fully support your tax and VAT filings, so you can focus on running and growing your business.

Choosing Accounting Software and Digital Tools Compliant with Danish Rules

When you run a sole proprietorship in Denmark, your choice of accounting software is not just a matter of convenience. It must support Danish bookkeeping rules, tax reporting and digital communication with the authorities. The right tools will save you time, reduce the risk of errors and make it easier to stay compliant with the Danish Business Authority (Erhvervsstyrelsen) and the Danish Tax Agency (Skattestyrelsen).

Key legal and practical requirements your software should meet

There is no single “approved” accounting system list in Denmark, but your software must allow you to comply with Danish bookkeeping legislation and tax rules. In practice, this means it should:

• Support double-entry bookkeeping and a clear audit trail for all transactions
• Store data securely in a way that prevents manipulation without trace
• Allow you to keep records for at least 5 years, as required by Danish bookkeeping rules
• Handle Danish VAT (moms) rates correctly, including 25% standard VAT and VAT-exempt sales
• Generate VAT reports that match the structure of the online VAT return in TastSelv Erhverv
• Export data in common formats (for example CSV, Excel or SAF-T compatible exports) so your accountant or auditor can review it
• Issue invoices that meet Danish invoicing requirements, including your CVR number, invoice date, sequential invoice number, description of goods/services, VAT amount and total

If you are required to submit digital bookkeeping data to the authorities or your business grows, having a system that can easily produce standardized exports will make inspections and collaboration with your accountant much smoother.

Cloud-based vs. local accounting systems

Most new sole proprietors in Denmark choose cloud-based accounting software. These systems are updated automatically when tax rules or VAT forms change, and they are easier to access from different devices. However, you remain responsible for ensuring that:

• The provider stores data within the EU/EEA or under agreements that comply with GDPR
• Backups are made regularly and can be restored if needed
• You can export your data if you change provider or close your business

Local (desktop) systems give you full control over where your data is stored, but you must handle backups and software updates yourself. For most sole proprietors, a reputable cloud solution is more practical and cost‑effective.

Essential features for Danish sole proprietors

When comparing accounting software and digital tools, look for features that specifically support Danish rules and everyday tasks:

• Danish chart of accounts: Predefined accounts that match typical Danish tax and VAT categories help you classify income and expenses correctly from day one.
• Automatic VAT calculation: The system should calculate 25% VAT on taxable sales and purchases, handle VAT-exempt items and reverse charge situations, and separate VAT from your revenue in reports.
• Integration with online banking: Bank feed integration with Danish banks (for example via PSD2) allows automatic import and matching of bank transactions, reducing manual work and errors.
• Support for EAN and electronic invoicing: If you sell to public institutions or some larger companies, you may need to send electronic invoices (e-faktura) via NemHandel or EAN. Your invoicing tool should support this.
• Multi-language and Danish localization: Even if you prefer English, it is useful if the system supports Danish terms, Danish date and number formats and local invoice templates.
• Mobile app for receipts: A mobile app that lets you photograph receipts and attach them directly to transactions makes it easier to document your expenses and comply with documentation requirements.

Digital tools for invoicing and payments

For many sole proprietors, invoicing and getting paid quickly is just as important as bookkeeping. Consider tools that:

• Generate professional invoices with your CVR number, payment terms and bank details clearly stated
• Allow you to add payment links (for example card payments or MobilePay) directly on the invoice
• Support Danish payment references (for example FIK or OCR) so incoming payments can be matched automatically
• Send automatic reminders for overdue invoices, in line with Danish rules on reminder fees and interest

Many accounting systems in Denmark include basic invoicing features. If you use a separate invoicing app, ensure it can synchronize with your main accounting software so your revenue and VAT are recorded correctly.

Compliance with Danish bookkeeping rules and GDPR

As a sole proprietor, you must be able to document all income and expenses and keep your records for at least 5 years. Your digital tools should make this easier, not harder. When choosing software, check that you can:

• Attach digital copies of receipts and invoices to each transaction
• Search and retrieve documents quickly in case of a tax inspection
• Lock accounting periods once you have submitted VAT or annual tax returns, so figures cannot be changed without a trace

Because you will often store personal data about customers and suppliers, your systems must also comply with GDPR. This means, among other things, having clear data processing agreements with your software providers, using strong passwords and two‑factor authentication, and restricting access to financial data to only those who need it.

Integration with TastSelv, payroll and other systems

Even if your accounting software cannot send data directly to TastSelv Erhverv, it should at least produce reports that match the structure of Danish VAT and tax forms. This reduces the risk of mistakes when you enter figures manually.

If you have employees, consider whether your accounting system integrates with Danish payroll solutions that handle A‑tax, AM‑bidrag and holiday pay. Integration between payroll and accounting reduces manual posting and helps ensure that salary costs and taxes are recorded correctly.

Costs, scalability and support

Most cloud-based accounting systems for small businesses in Denmark charge a monthly subscription. When comparing prices, look beyond the basic fee and check:

• How many invoices, bookings or bank transactions are included per month
• Whether bank integration, e‑invoicing or additional users cost extra
• Whether you can upgrade easily if your business grows or you hire employees
• What kind of support is available (email, chat, phone) and in which languages

For a typical sole proprietorship, it is usually worth paying for a system that saves several hours of manual work each month and reduces the risk of VAT or tax errors. Many providers offer free trials, so you can test the interface and features before committing.

How an accountant can help you choose the right tools

Even if you plan to do your own bookkeeping, it is often useful to involve an accountant when choosing software. An accountant familiar with Danish rules can:

• Recommend systems that fit your industry and volume of transactions
• Set up your chart of accounts and VAT codes correctly from the start
• Show you how to record typical transactions, such as mileage, home office costs or equipment purchases
• Review your first periods to ensure that your records and reports are accurate

Choosing accounting software and digital tools that are fully compliant with Danish rules from the beginning will make your sole proprietorship easier to manage, reduce stress around VAT and tax deadlines and give you a clearer picture of your business finances.

Understanding A‑tax, AM‑bidrag and B‑income for Sole Proprietors

A‑tax, AM‑bidrag and B‑income are three core concepts you must understand as a sole proprietor in Denmark. They determine how your income is taxed, how much labour market contribution you pay, and how you should report and pay tax during the year.

What is AM‑bidrag (labour market contribution)?

AM‑bidrag is a mandatory labour market contribution that you pay on almost all types of earned income. It is calculated before income tax and currently amounts to 8% of your AM‑bidragsgrundlag (AM contribution base).

For a sole proprietor, the AM contribution base typically includes:

• Profits from your sole proprietorship (business income)
• Salary from employment (if you also have a job)
• Certain benefits linked to work, such as some fringe benefits

AM‑bidrag is always calculated first. Only after the 8% has been deducted is your remaining income used as the basis for A‑tax and other income taxes.

What is A‑tax?

A‑tax is the income tax that is withheld at source on A‑income. For employees, the employer withholds A‑tax and AM‑bidrag each month and pays it directly to Skattestyrelsen. As a sole proprietor, the situation depends on how you receive your income:

• If you only have business income from your sole proprietorship, this is normally treated as B‑income, not A‑income. You then pay tax via on‑account tax (B‑skat), not via A‑tax withholding.
• If you also have a regular job, your employer withholds A‑tax and AM‑bidrag on your salary as usual.

A‑tax is calculated on your income after AM‑bidrag has been deducted. The total tax rate depends on your municipality, church tax (if applicable) and whether your income exceeds the top tax threshold.

What is B‑income for a sole proprietor?

B‑income is income where no tax or AM‑bidrag is withheld at source. For most sole proprietors, the profit from the business is treated as B‑income. Typical examples of B‑income include:

• Profits from your sole proprietorship (self‑employed business income)
• Fees and honoraria where the payer does not withhold tax
• Side income such as freelance work invoiced directly by you

Because no one withholds tax on B‑income, you must yourself ensure that tax and AM‑bidrag are paid on time through your preliminary income assessment and B‑tax instalments.

How A‑tax, AM‑bidrag and B‑income work together

For a sole proprietor, the typical flow looks like this:

1. You earn income in your business. This is B‑income.
2. You calculate your expected annual profit and enter it in your preliminary income assessment (forskudsopgørelse) on skat.dk.
3. Skattestyrelsen calculates how much AM‑bidrag (8%) and income tax you are expected to pay on this B‑income.
4. This amount is split into 10 monthly B‑tax instalments (January–May and August–December). June and July normally have no scheduled B‑tax instalments.
5. You pay these instalments yourself via online banking or directly through skat.dk.

If you also have A‑income from employment, your employer withholds AM‑bidrag and A‑tax on that part of your income. At the end of the year, all income (A‑ and B‑income) and all taxes paid are combined in your annual tax assessment.

Current tax structure relevant for sole proprietors

When you pay tax on your B‑income, the following elements are typically included:

• AM‑bidrag: 8% of your AM contribution base
• Municipal tax: varies by municipality, usually around 24–27% of your taxable income after AM‑bidrag
• Health contribution replacement: included in the municipal tax rate
• Church tax (if you are a member of the Folkekirken): typically around 0.4–1.3%
• Bottom tax: state tax of 12.09% on taxable income above the personal allowance
• Top tax: state tax of 15% on personal income above the top tax threshold (around DKK 588,900 after AM‑bidrag, excluding pension contributions)

You also have a personal allowance (personfradrag) that reduces the income on which you pay bottom and municipal tax. For adults, this allowance is a fixed amount in DKK and is adjusted regularly.

How to handle B‑income in practice

To avoid unexpected tax bills, you should:

• Estimate your annual business profit as realistically as possible
• Update your preliminary income assessment on skat.dk whenever your income changes significantly
• Set aside money for tax and AM‑bidrag throughout the year, for example 40–50% of your profit depending on your total income and municipality
• Pay your B‑tax instalments by the due dates stated on skat.dk

If your actual profit turns out higher than expected, you can make extra voluntary payments of B‑tax during the year or before the final deadlines to reduce interest and surcharges.

Deadlines and payment of B‑tax

B‑tax is usually paid in 10 instalments with fixed monthly due dates. If your expected B‑income is below a certain threshold, Skattestyrelsen may instead collect the tax as a single payment after the end of the year. If your expected B‑income is higher, you will automatically receive a B‑tax schedule.

Missing or late B‑tax payments can lead to interest and fees, so it is important to monitor your payment overview on skat.dk regularly.

Combining employment and a sole proprietorship

Many sole proprietors also have a regular job. In that case:

• Your salary is A‑income with A‑tax and AM‑bidrag withheld by your employer
• Your business profit is B‑income, taxed via B‑tax instalments
• Your tax card (skattekort) should be set up so that your main card (hovedkort) is used by your employer, and your business income is included in your preliminary income assessment

This ensures that your personal allowance and tax deductions are used correctly, and that you do not end up with a large underpayment when the annual tax assessment is issued.

Why correct classification of income matters

Correctly distinguishing between A‑income and B‑income is crucial for:

• Ensuring that AM‑bidrag and tax are calculated correctly
• Avoiding underpayment and interest on tax
• Using your personal allowance and deductions optimally
• Documenting your income properly in case of a tax audit

If you are unsure whether a specific type of income should be treated as A‑ or B‑income, or how to set up your preliminary income assessment, it is advisable to seek professional accounting support. Proper handling from the start makes running your sole proprietorship in Denmark significantly smoother and more predictable from a tax perspective.

Deductible Business Expenses and Common Tax Deductions in Denmark

As a sole proprietor in Denmark, understanding which costs are tax-deductible can significantly reduce your overall tax burden. Danish tax rules allow you to deduct expenses that are directly related to earning your business income, provided they are properly documented and recorded in your accounts.

General principles for deducting business expenses

You can usually deduct an expense if it:

• Is incurred solely or primarily for business purposes
• Is necessary to run or maintain your business
• Is documented with an invoice or receipt that shows date, supplier, amount and content
• Is recorded correctly in your bookkeeping and bank statements

Private expenses are never deductible. If a cost has both private and business use, you may only deduct the business-related share. You must be able to justify the split if SKAT (the Danish Tax Agency) asks.

Typical deductible expenses for sole proprietors

Most running costs that are directly linked to your business activity are deductible, for example:

• Office costs: rent for business premises, office supplies, internet, phone subscriptions, software licences
• Marketing and sales: website hosting, advertising, business cards, online ads, trade fairs and exhibitions
• Professional services: accounting and bookkeeping fees, legal advice, business consulting
• Insurance: business liability insurance, professional indemnity insurance, relevant business property insurance
• Bank and payment fees: fees on business accounts, payment gateway costs, card fees
• Small equipment and tools: computers, phones, tools and other equipment with a limited value or short useful life

Expenses must be reasonable in relation to the size and nature of your business. Excessive or clearly private-related costs are likely to be rejected by SKAT.

Home office and mixed-use expenses

If you run your business from home, you may be able to deduct part of your housing and utility costs. The rules differ depending on whether you have a clearly separated business area or you use common rooms.

• Separate business premises in your home: If a room is used exclusively and permanently for business (for example, a dedicated office with its own entrance), you can usually deduct a proportionate share of rent, interest on mortgage, property taxes and utilities based on the area used for business.
• Shared rooms (no clear separation): If you work from your living room or kitchen, you normally cannot deduct rent or mortgage costs. In this case, you typically only deduct direct business costs such as internet, phone and office equipment, and sometimes a reasonable share of these if they are also used privately.

You must be able to document how you calculated the business share (for example, square metres or actual usage). Keep your calculation with your accounting records.

Travel, transport and mileage

Travel and transport are deductible when they are directly related to your business, such as visiting customers, suppliers or attending courses.

• Public transport and taxis: fully deductible when used for business travel and documented with receipts.
• Business travel with overnight stay: you can deduct actual documented costs for transport, accommodation and necessary meals. In some cases, you may use standard allowances for meals and small expenses if you meet the conditions set by SKAT.
• Use of private car for business: you can either deduct a mileage allowance based on SKAT’s official rates per kilometre or deduct the business share of actual car costs. You cannot combine both methods for the same car in the same year.

To use mileage deduction, you must keep a mileage log that shows date, purpose, route and kilometres driven for each business trip. The deduction is calculated by multiplying business kilometres by the applicable SKAT rate for that year.

Car expenses and business vehicles

If you use a car both privately and for business, you must choose a tax method:

• Private car with mileage deduction: the car is treated as private, and you deduct only business kilometres using SKAT’s mileage rate. You do not deduct fuel, insurance or repairs separately.
• Business car: the car is registered as a business asset. You deduct all car-related costs (fuel, insurance, repairs, depreciation), but you may be taxed on private use of the car, typically through a taxable value of free car if the car is also available for private driving.

The choice has long-term tax consequences and should be made carefully. For many small sole proprietors, a private car with mileage deduction is often simpler and more tax-efficient, especially if business driving is limited.

Depreciation of assets and investments

Larger purchases that are used over several years, such as machinery, vehicles, expensive tools or IT equipment, are usually not deducted in full in the year of purchase. Instead, you depreciate them over time according to Danish tax rules.

• Depreciation pools: many assets are grouped in a depreciation pool where you can deduct a percentage of the remaining value each year.
• Immediate deduction of small assets: assets below a certain value threshold can often be expensed immediately instead of being depreciated over several years.

Correct depreciation planning can smooth your taxable income over time and avoid large fluctuations in your tax bill.

Education, courses and professional development

Expenses for courses, seminars and continuing education are usually deductible if they maintain or update your existing professional skills used in your business. This can include:

• Short courses directly related to your current business area
• Mandatory continuing education required for your profession
• Conferences and trade events with a clear professional purpose

Costs for basic education or training that qualifies you for a new profession are generally not deductible as business expenses. The key question is whether the education maintains existing skills or creates a new income base.

Interest, financing costs and losses

Interest on business loans, overdrafts and leasing agreements is normally deductible. You can also deduct reasonable bank fees related to your business accounts and payment solutions.

Losses on unpaid customer invoices (bad debts) can be deductible if you can show that you have tried to collect the payment and that the loss is real, for example through reminders, collection procedures or bankruptcy of the customer.

Non-deductible or limited-deduction expenses

Certain types of expenses are either not deductible or only partly deductible under Danish tax law. Typical examples include:

• Private living costs: food, clothing, rent for your home (unless a clearly separated business area), private phone and internet use
• Fines and penalties: parking tickets, speeding fines and other penalties are never deductible
• Representation and entertainment: business meals and entertainment of clients are often only partly deductible and subject to strict documentation requirements
• Gifts: business gifts have limited deductibility and must meet specific conditions (for example, low value, clear business purpose and proper documentation)

When in doubt, treat an expense as non-deductible until you have verified the rules or consulted an accountant.

Common tax deductions for sole proprietors

In addition to direct business expenses, there are several important deductions that affect your overall tax as a sole proprietor:

• Labour market contribution (AM-bidrag): 8% is calculated on your business profit before income tax. This is mandatory and not a deduction you can avoid, but it reduces the base for your personal income tax.
• Pension contributions: contributions to approved pension schemes are usually deductible within annual limits. This can be an effective way to reduce your taxable income while saving for retirement.
• Interest on private loans: interest on private loans (for example, mortgage on your home) is normally deductible in your personal tax, even if it is not a business expense, and will affect your total tax bill.
• Personal allowances: as a sole proprietor you still benefit from the general personal allowance and other personal deductions that reduce your total tax.

Documentation and bookkeeping requirements

To claim deductions, you must keep proper records that meet Danish bookkeeping standards. This includes:

• Storing invoices and receipts for all income and expenses, usually for at least five years
• Keeping a clear separation between business and private transactions, ideally with a dedicated business bank account
• Maintaining a mileage log for business driving if you use mileage deduction
• Documenting allocation keys for mixed-use costs (for example, home office, phone, car)

Good documentation not only secures your deductions but also makes it easier to prepare your annual tax return and respond to any questions from SKAT.

Optimising your deductions with professional help

Danish tax rules for sole proprietors are detailed and change regularly. Using an accountant or tax advisor who understands the specific rules for self-employed persons in Denmark can help you:

• Identify all relevant deductible expenses
• Choose the most tax-efficient methods for car use, depreciation and pension contributions
• Avoid common mistakes that lead to rejected deductions or unnecessary tax payments

Well-structured bookkeeping and a clear deduction strategy will ensure that you only pay the tax you are legally required to pay and that your sole proprietorship in Denmark remains financially healthy and compliant.

Handling Invoicing, Payment Terms and Late Payment Rules

Clear and compliant invoicing is essential for any sole proprietorship in Denmark. It affects your cash flow, tax reporting and your relationship with customers. Below you will find the key rules on what an invoice must contain, how to set payment terms and how to handle late payments under Danish law.

Mandatory information on Danish invoices

If you run a sole proprietorship and issue invoices to customers, you must ensure that every invoice includes at least the following information:

• Your full business name and address as registered with the Danish Business Authority
• Your CVR number (or CPR number if you are not VAT registered and invoice as a private individual, which is generally not recommended for business activity)
• The customer’s name and address; for business customers in the EU, their VAT number if relevant
• A unique, consecutive invoice number that fits into a continuous number series
• Invoice date and, if different, the date of delivery or completion of the service
• Clear description of the goods or services supplied, including quantity and unit price
• Net amount (price before VAT) per line and in total
• Applicable VAT rate (typically 25% in Denmark) and the VAT amount in DKK
• Total amount payable including VAT
• Currency, if not invoicing in DKK
• Payment terms and due date

If the supply is VAT exempt (for example certain financial services, health services or education), you should clearly state the legal reason for the exemption on the invoice, such as “VAT exempt according to Danish VAT Act”.

Electronic invoicing and e‑invoices to public authorities

When you sell to Danish public authorities (the state, regions or municipalities), you must send an electronic invoice (e‑invoice) in the OIOUBL / NemHandel format. Paper or PDF invoices are not accepted by the public sector. To issue e‑invoices you typically need:

• A CVR number and, if relevant, a VAT registration
• Access to an e‑invoicing solution (for example via your accounting software or a NemHandel-compliant portal)
• The EAN number of the public customer and any reference information they require (for example order number or contact person)

For private customers and private companies, PDF or paper invoices are still widely used, but many businesses prefer fully digital invoicing through accounting software that integrates with banks and payment providers.

Setting payment terms on your invoices

As a sole proprietor you are free to agree payment terms with your customers, as long as they are not unfair under Danish law. Common payment terms in Denmark include:

• Immediate payment (for example “cash on delivery” or online card payment)
• Net 8 days
• Net 14 days
• Net 30 days

For business-to-business sales, payment terms longer than 30 days can be considered unreasonable if they are clearly to the detriment of the supplier, especially for small businesses. Always state the due date explicitly on the invoice, for example “Payment terms: 14 days – due on [date]”.

If you charge fees for reminders or late payment interest, you must also mention this in your terms and conditions or on the invoice, so customers know what applies in case of late payment.

Late payment interest under Danish rules

When a customer pays after the due date, you are entitled to charge late payment interest. If you have not agreed a specific interest rate in your contract or terms, you can use the statutory interest rate under the Danish Interest Act. This rate is:

• The official reference rate set by Danmarks Nationalbank, plus 8 percentage points per year

The reference rate is adjusted twice a year. The effective annual interest rate therefore changes over time. You calculate interest from the day after the due date until the day payment is received. Interest is usually calculated on a daily basis using the annual rate divided by 365.

You may agree a different contractual interest rate with your customers, but it must be reasonable and clearly communicated in advance. For consumer customers, especially, the rate must not be excessive or misleading.

Reminder fees and compensation for collection costs

In addition to interest, Danish law allows you to charge certain reminder and collection fees when invoices are not paid on time, provided you follow the rules:

• You may send up to three written payment reminders for the same overdue invoice.
• You may charge a reminder fee of up to 100 DKK per reminder.
• There must be at least 10 days between each reminder.

For business customers (B2B), you may also charge a standard compensation fee of 310 DKK for recovery costs on overdue invoices, in addition to reminder fees and interest. This fee can normally be charged once per overdue invoice when the claim is transferred to collection or when you initiate formal recovery steps.

All reminder fees and compensation fees should be clearly listed on the reminder letter or invoice, so the customer can see how the total amount has been calculated.

Best practices to reduce late payments

To protect your cash flow and reduce the risk of late payments, consider the following practices:

• Use clear and simple payment terms on all offers, contracts and invoices.
• Invoice immediately after delivering goods or completing services.
• Offer convenient payment options such as bank transfer, MobilePay, card payments or payment links.
• Send friendly reminders shortly before the due date and immediately after it passes.
• For larger projects, use deposits or milestone payments to spread the risk.
• Check the creditworthiness of new business customers before offering long credit periods.

Well-structured invoicing and consistent follow-up not only improve your liquidity but also support accurate bookkeeping and tax reporting for your Danish sole proprietorship.

Insurance Needs for Sole Proprietors (Liability, Accident, Professional Indemnity)

Even though many types of business insurance are not legally mandatory for Danish sole proprietors, having the right cover can protect both your company and your personal finances. As a sole trader, there is no legal separation between you and your business, so a single claim or accident can directly affect your private assets. Understanding which insurances are relevant in Denmark helps you manage risk in a structured way.

Public vs. private liability in Denmark

In Denmark, private liability is usually covered through a household or family insurance, but this does not automatically cover business activities. As soon as you invoice customers, visit clients, work at their premises or have customers visiting you, you should consider separate business liability insurance.

Business liability insurance (erhvervsansvarsforsikring)

Business liability insurance covers compensation claims if your business causes personal injury or property damage to others in the course of your work. For many professions, especially those working physically at a client’s location (craftsmen, consultants on-site, IT technicians, photographers, therapists), this is one of the most important policies.

Typical features of Danish business liability insurance include:

• Coverage for personal injury and property damage caused by you or your employees during business activities
• Legal defence costs if a claim is brought against you
• Coverage limits often starting around DKK 2–5 million per claim, with higher limits available for riskier industries
• A deductible (own risk) per claim, typically from DKK 1,000 to DKK 10,000 depending on premium level

Some industries or clients may require proof of liability insurance in contracts or framework agreements. If you work as a subcontractor for larger companies or public institutions, they may specify minimum coverage amounts, for example DKK 5–10 million per claim.

Product liability insurance (produktansvarsforsikring)

If your sole proprietorship manufactures, imports, modifies or sells physical products, you can be held liable for damage caused by a defective product under Danish and EU product liability rules. Product liability insurance can be added as a separate module or as part of a broader business policy.

It is particularly relevant if you:

• Produce or assemble goods or components
• Import products from outside the EU/EEA
• Sell products under your own brand or label

Coverage limits for product liability are often higher than for general liability, for example DKK 10–25 million per year, depending on turnover and risk profile.

Professional indemnity insurance (erhvervs- og rådgiveransvar)

Professional indemnity insurance covers financial losses your client suffers due to errors, negligence or omissions in your professional advice or services. This is especially relevant for knowledge-based and advisory professions, such as:

• Accountants and bookkeepers
• Tax and legal advisers
• IT consultants, developers and system architects
• Engineers, architects and designers
• Business, marketing and management consultants

In some regulated professions (for example state-authorised public accountants, lawyers and certain financial advisers), professional indemnity insurance is a practical requirement to operate, and professional bodies may set minimum coverage levels. Even when not legally mandatory, many clients in Denmark expect consultants to have professional indemnity and may ask for documentation before signing a contract.

Typical Danish professional indemnity policies:

• Cover pure financial loss (økonomisk tab) caused by your professional mistake
• Include legal defence costs and negotiation with the claimant
• Offer coverage limits often starting from DKK 1–2 million per year, with higher limits for high-risk sectors
• May exclude intentional misconduct, fines and certain contractual guarantees

Accident insurance for you and your employees

As a sole proprietor without employees, you are not automatically covered by the Danish Workers’ Compensation Act (arbejdsskadesikringsloven). You can, however, take out a voluntary work injury insurance (frivillig arbejdsskadeforsikring) for yourself, which is often recommended if your work involves physical tasks, driving or visits to client sites.

If you employ staff, you must as a rule take out mandatory work injury insurance for each employee. This insurance covers:

• Occupational accidents and occupational diseases
• Compensation for permanent injury and loss of earning capacity
• Certain treatment and rehabilitation costs

Premiums depend on industry, risk level and payroll. High-risk sectors such as construction and manufacturing pay significantly higher rates than office-based businesses.

In addition to statutory work injury insurance, many sole proprietors choose:

• Private accident insurance for themselves, covering both work and leisure time
• Health insurance (sundhedsforsikring) to get faster access to treatment and reduce downtime

Contents, equipment and cyber insurance

Even though they are not strictly liability or accident insurances, several other policies are often relevant for Danish sole proprietors:

• Business contents insurance (løsøreforsikring) – covers office furniture, IT equipment, tools and inventory against fire, theft, water damage and vandalism. If you work from home, your private home insurance usually does not fully cover business equipment, especially if customers visit your home office.
• Electronics and portable equipment insurance – covers laptops, phones, cameras and tools you carry outside your office, including during travel.
• Cyber insurance – covers costs related to data breaches, hacking, ransomware, data recovery and sometimes GDPR-related advisory costs. This is increasingly relevant for businesses processing personal data or depending heavily on IT systems.

Car and transport insurance

If you use a car for business purposes, you must have at least the mandatory third-party liability insurance (ansvarsforsikring) for the vehicle. If the car is registered as a company car, you typically need a commercial motor insurance. If you use a private car partly for business, you should inform your insurer, as extensive business use may require an adjustment of your policy.

For businesses transporting goods or equipment, transport insurance (varetransportforsikring) can cover damage or loss during transport, both in Denmark and abroad.

How to choose the right insurance package

When assessing which insurances your Danish sole proprietorship needs, consider:

• The nature of your services or products and the potential size of a claim
• Whether you work at your own premises, at clients’ premises or online only
• Contractual requirements from clients, public authorities or professional bodies
• Whether you have employees or plan to hire
• The value of your equipment, inventory and data

Many Danish insurers offer combined business packages for small enterprises, which can include liability, contents, accident and sometimes cyber cover at a lower total premium than separate policies. It is often worth obtaining offers from several insurers or working with an insurance broker who understands small business risks.

Documentation and integration with your accounting

Keep all insurance policies, terms and premium invoices organised and accessible. Premiums for business-related insurances are generally deductible business expenses in Denmark and should be booked correctly in your accounts. When renewing or changing policies, review coverage limits and exclusions to ensure they still match your turnover, risk profile and contractual obligations.

By actively managing your insurance needs as a sole proprietor, you reduce the risk that an unexpected claim, accident or data incident will threaten the continuity of your business or your personal finances.

Data Protection (GDPR) Obligations for Small Business Owners

When you run a sole proprietorship in Denmark, you are almost always processing personal data – for example about customers, newsletter subscribers or employees. This means the EU General Data Protection Regulation (GDPR) and the Danish Data Protection Act (databeskyttelsesloven) apply to you, even if your business is very small or you only work part‑time.

Are you a data controller or a data processor?

Most sole proprietors are data controllers. You decide why and how personal data is processed – for example when you collect customer details to issue invoices or send offers. You are a data processor only when you process personal data on behalf of another company and follow their instructions, for example as an external bookkeeper or IT provider. In many cases you can be both, depending on the specific activity.

As a data controller you are responsible for complying with GDPR principles and for being able to document that compliance if the Danish Data Protection Agency (Datatilsynet) asks.

Key GDPR principles you must follow

Your processing of personal data must always comply with these core principles:

• Lawfulness, fairness and transparency – you must have a legal basis (for example contract, legal obligation, legitimate interest or consent) and be open about what you do with the data.
• Purpose limitation – collect data only for specific, explicit and legitimate purposes and do not use it for incompatible purposes later.
• Data minimisation – collect only the data you actually need, not “nice to have” information.
• Accuracy – keep data up to date and correct or delete inaccurate information.
• Storage limitation – do not keep personal data longer than necessary for the purpose or for statutory retention periods.
• Integrity and confidentiality – protect data against unauthorised access, loss or damage with appropriate technical and organisational measures.
• Accountability – you must be able to show how you comply, for example with written procedures and documentation.

What counts as personal data in your business?

Personal data is any information that can identify a living person directly or indirectly. For a Danish sole proprietorship this often includes:

• Customer names, addresses, phone numbers and email addresses
• CPR numbers when required for specific services or reporting
• Bank account details and payment information
• IP addresses and online identifiers from your website or webshop
• Employee data such as salary details, tax information and absence records

Some categories, such as health data, trade union membership, religious beliefs or biometric data, are considered sensitive and are subject to stricter rules. You should avoid processing sensitive data unless it is clearly necessary and you have a valid legal basis.

Information you must give to customers and contacts

GDPR requires you to inform people when you collect their personal data. This is usually done in a privacy policy on your website and in relevant forms or contracts. As a minimum, you must clearly explain:

• Who you are (business name, CVR number and contact details)
• What types of personal data you collect
• For which purposes and on what legal basis you process the data
• How long you keep the data or the criteria used to determine retention periods
• Who you share data with (for example your accountant, hosting provider, payment gateway)
• Whether data is transferred outside the EU/EEA and on what safeguards
• What rights the person has and how they can exercise them

Handling data subject rights

Individuals whose data you process have specific rights under GDPR. As a sole proprietor you must have simple procedures to handle:

• Right of access – a person can ask what data you hold about them and receive a copy.
• Right to rectification – they can ask you to correct inaccurate or incomplete data.
• Right to erasure – in some cases they can ask you to delete their data, for example when it is no longer needed. You may keep data that must be stored by law, for example for bookkeeping.
• Right to restriction and objection – they can object to certain processing, for example direct marketing, or ask you to limit processing while a dispute is being resolved.
• Right to data portability – for some data processed based on consent or contract, they can ask to receive it in a structured, commonly used format.

You must normally respond without undue delay and at the latest within one month. In complex cases this can be extended, but you must inform the person and explain why.

Data processing agreements with suppliers

If you use external suppliers that process personal data on your behalf – for example cloud accounting software, email marketing tools, web hosting or payroll providers – you must sign a written data processing agreement (databehandleraftale) with each of them.

The agreement must describe the subject and duration of the processing, the nature and purpose, the type of personal data, the categories of data subjects and the obligations and rights of both parties. You must ensure that the processor implements appropriate security measures and only processes data according to your documented instructions.

Transferring data outside the EU/EEA

If your tools or service providers store or access personal data from outside the EU/EEA, you must ensure that the transfer is lawful. This typically requires:

• An adequacy decision from the European Commission for the destination country, or
• Standard Contractual Clauses (SCCs) combined with a transfer risk assessment and, if needed, additional safeguards.

Many popular cloud services used by Danish small businesses rely on SCCs. You should know where your data is stored and be able to document the legal basis for any international transfers.

Security measures for small businesses

GDPR does not prescribe specific technologies but requires “appropriate” security based on the risks. For a Danish sole proprietorship, typical measures include:

• Strong, unique passwords and multi‑factor authentication for email, accounting and banking
• Encrypted devices (laptops, phones) and regular software updates
• Limiting access to personal data to only what is necessary for your work
• Secure backup routines for accounting and customer data
• Using reputable, GDPR‑compliant cloud services instead of unprotected local storage

If you have employees, you should also provide basic data protection training and clear internal rules on handling customer and employee data.

Data breach obligations

A personal data breach is any security incident that leads to accidental or unlawful destruction, loss, alteration, unauthorised disclosure of, or access to personal data. This can include a lost laptop, an email sent to the wrong recipient or a hacked mailbox.

If a breach is likely to result in a risk to the rights and freedoms of individuals, you must notify the Danish Data Protection Agency without undue delay and, where feasible, within 72 hours of becoming aware of it. If the risk is high, you may also need to inform the affected individuals directly in clear language.

Record‑keeping and documentation

Under GDPR, many businesses must keep a record of processing activities. Even if your sole proprietorship is small and might qualify for some exemptions, it is strongly recommended to maintain at least a simple overview of:

• Which categories of personal data you process and for what purposes
• Legal bases for each processing activity
• Retention periods and deletion routines
• Data processors and other recipients of personal data
• Security measures you have implemented

This documentation helps you stay compliant and is valuable if Datatilsynet asks for information or if a customer questions your data practices.

Marketing, cookies and consent

If you send electronic marketing in Denmark, you must comply with both GDPR and the Danish Marketing Practices Act (markedsføringsloven). As a rule, you need prior consent to send marketing emails or SMS to private individuals, with limited exceptions for existing customer relationships and similar products.

If your website uses cookies or similar tracking technologies that are not strictly necessary (for example for statistics, analytics or advertising), you must obtain valid consent before placing them, in line with the Danish cookie rules and GDPR. Consent must be informed, specific, freely given and as easy to withdraw as to give.

When you need a Data Protection Officer

Most sole proprietorships in Denmark do not need to appoint a Data Protection Officer (DPO). A DPO is required mainly for public authorities or private organisations that carry out large‑scale systematic monitoring or large‑scale processing of sensitive data. However, you can always seek external advice from a consultant or your accountant if your processing is complex or involves high risks.

Practical GDPR checklist for your sole proprietorship

To keep your Danish sole proprietorship compliant with GDPR, make sure you:

• Map what personal data you collect, why you collect it and how long you keep it
• Have a clear, up‑to‑date privacy policy in English or Danish
• Use written data processing agreements with all relevant suppliers
• Implement basic technical and organisational security measures
• Have simple procedures for handling access, correction and deletion requests
• Know how you will detect and handle a data breach within the 72‑hour deadline
• Review your practices regularly as your business grows or changes

Building GDPR compliance into your daily routines from the start not only reduces legal risk and potential fines, but also strengthens trust with your customers, partners and employees in the Danish market.

Common Mistakes When Registering a Sole Proprietorship and How to Avoid Them

Many founders rush through the registration of a sole proprietorship in Denmark and only discover mistakes when SKAT, Erhvervsstyrelsen or a bank asks questions. Below are the most common pitfalls we see in practice – and how you can avoid them from the start.

1. Registering Too Late (or Not at All)

A frequent mistake is waiting too long to register the business with the Danish Business Authority (Erhvervsstyrelsen) via Virk.dk. You must register when you start carrying out business activities with the intention of making a profit – not only when you send your first invoice.

If your annual turnover exceeds DKK 50,000 within a 12‑month period, you are required to register for VAT (moms). Failing to register on time can lead to retroactive VAT, interest and possible penalties. To avoid this, monitor your turnover from day one and complete registration as soon as it becomes clear that you will reach the threshold.

2. Choosing a Business Name That Conflicts With Existing Rights

Another common error is picking a business name that is already in use or conflicts with a protected company name or trademark. This can result in a forced name change, new stationery, website changes and even legal disputes.

Before you register, check name availability on the Central Business Register (CVR) and search for existing trademarks in Denmark and the EU. Avoid using names that are too similar to well‑known brands or existing companies in your industry. If you plan to build a strong brand, consider registering a trademark early.

3. Incorrect or Incomplete Information in the Registration

Many sole proprietors rush through the online forms and make mistakes in key fields such as business activity (branchekode), address, contact details or expected turnover. Wrong information can affect your tax pre‑assessment, VAT status and even insurance coverage.

Take time to select the correct industry code that best reflects your main activity. Make sure your business address and contact details are up to date and that you update them promptly if you move or change phone number or email. This ensures that letters and digital messages from SKAT and other authorities reach you.

4. Misunderstanding VAT (Moms) Obligations

Many new sole proprietors either register for VAT too early without understanding the consequences, or too late when they already exceed the DKK 50,000 threshold. Others forget to charge VAT on invoices or fail to submit VAT returns on time.

If you are VAT‑registered, you must:

• Charge 25% VAT on most goods and services (unless exempt)
• Issue VAT‑compliant invoices with your CVR number, VAT amount and date
• Submit VAT returns and pay VAT within the deadlines set for your reporting period

Late or missing VAT returns can lead to estimated assessments, surcharges and interest. Set up reminders and, if possible, use accounting software that calculates VAT automatically and reminds you of deadlines.

5. Not Understanding A‑tax, AM‑bidrag and B‑income

Many sole proprietors mix up different types of income and tax. If you have both employment income (A‑income) and business income (typically B‑income), you must ensure that your preliminary tax assessment (forskudsopgørelse) reflects this correctly.

Business profits are subject to labour market contribution (AM‑bidrag) of 8% and then personal income tax according to the applicable tax brackets. If you do not adjust your preliminary assessment, you risk a large tax bill when the annual tax statement is issued. Update your forskudsopgørelse as soon as you start your business and whenever your expected profit changes significantly.

6. Mixing Personal and Business Finances

Because a sole proprietorship is not a separate legal entity, many owners use the same bank account for private and business transactions. This makes bookkeeping difficult, increases the risk of errors and complicates tax audits.

Even though you are not legally required to have a separate business account, it is strongly recommended. Use one account for all business income and expenses and keep private spending separate. This simplifies your bookkeeping, makes your cash flow clearer and reduces the risk of missing deductible expenses.

7. Poor or Non‑Compliant Bookkeeping

Some new business owners underestimate the importance of proper bookkeeping and keep only sporadic notes or shoe‑box receipts. Danish bookkeeping rules require that you keep orderly records and documentation for all income and expenses for at least five years.

Common mistakes include missing invoices, no numbering of invoices, lack of documentation for cash payments and not reconciling bank statements. To avoid problems during a tax inspection, implement a simple but consistent system from day one. Use accounting software that complies with Danish requirements, store receipts digitally and reconcile your accounts regularly.

8. Overlooking Deductible Expenses and Allowances

Many sole proprietors pay more tax than necessary because they do not claim all legitimate business deductions. Typical examples include home office expenses, telephone and internet, travel and mileage, professional courses and equipment.

However, another mistake is deducting private expenses as business costs. This can lead to corrections, additional tax and penalties. Make sure you understand which expenses are fully deductible, partially deductible or not deductible at all, and keep clear documentation for each cost.

9. Ignoring Employer Obligations When Hiring Help

Some sole proprietors start by paying helpers “informally” without registering as an employer. In Denmark, if you hire employees, you must register as an employer, withhold A‑tax and AM‑bidrag, report salary information (eIndkomst) and comply with holiday and employment law rules.

Misclassifying employees as freelancers or paying wages without proper reporting can lead to significant back taxes, social contributions and fines. Before you hire, clarify whether the person is an employee or a genuine independent contractor and set up the correct payroll procedures.

10. Forgetting About Insurance and Liability

Because a sole proprietorship is not a separate legal entity, you are personally liable for all business obligations. Many owners underestimate this risk and start operating without appropriate insurance.

Depending on your activity, you may need professional liability insurance, product liability insurance, business contents insurance or accident insurance. In some professions, certain insurances are effectively mandatory to work with larger clients. Review your risk profile early and arrange suitable coverage before you start serving customers.

11. Not Considering GDPR and Data Protection

Even very small businesses often process personal data from customers, suppliers or employees. A common mistake is assuming that GDPR does not apply to “small” sole proprietors.

You must handle personal data lawfully, inform data subjects about how you use their data, secure your IT systems and, where relevant, enter into data processing agreements with external providers such as cloud services or accounting platforms. Failing to do so can lead to complaints, reputational damage and, in serious cases, fines.

12. No Plan for Growth or Conversion to ApS

Many founders register a sole proprietorship without thinking about how the structure will fit their business in two or three years. As profits and risks grow, it may be more advantageous to convert to a private limited company (ApS) to limit personal liability and optimise taxation.

A common mistake is waiting too long to consider this, which can complicate the transfer of assets, contracts and financing. From the start, keep your records and contracts in a way that makes a future conversion smoother, and review your structure regularly as your business develops.

By being aware of these typical mistakes and addressing them proactively, you can register your sole proprietorship in Denmark smoothly, stay compliant with Danish rules and focus your time and energy on growing your business instead of fixing avoidable problems later.

When and How to Convert Your Sole Proprietorship into an ApS (Private Limited Company)

Many entrepreneurs in Denmark start as sole proprietors (enkeltmandsvirksomhed) and later convert to a private limited company (ApS). Converting at the right time can reduce your personal risk, optimise taxation and make your business more attractive to clients, banks and investors.

When does it make sense to convert to an ApS?

You should consider changing from a sole proprietorship to an ApS when one or more of the following apply:

• Growing profit and higher personal tax – As your profit increases, more of your income is taxed at the top personal tax rate. In 2024 the top tax (topskat) applies to personal income above approx. DKK 588,900 (after AM-bidrag). At that point, keeping some profit in a company at the corporate tax rate of 22% can be more efficient than being taxed fully as personal income.
• Need to limit personal liability – In a sole proprietorship you are personally liable for all business debts and obligations. An ApS is a separate legal entity, and your risk is generally limited to the company’s capital, typically DKK 40,000 in share capital plus any guarantees you have given personally.
• Working with larger clients or public tenders – Many corporate and public clients prefer or require suppliers to operate via a limited company for risk and compliance reasons.
• Bringing in co‑owners or investors – It is far easier to issue shares, bring in partners and structure ownership through an ApS than through a sole proprietorship.
• Planning to sell the business – A share sale of an ApS can be more flexible and tax‑efficient than selling the assets of a sole proprietorship, especially if you plan a gradual exit.

There is no legal requirement to convert at a specific turnover or profit level, but once your business is stable, profitable and carries financial or contractual risk, an ApS is usually worth serious consideration.

Key differences between a sole proprietorship and an ApS

Before converting, it is important to understand what will change in practice:

• Legal status – An ApS is a separate legal person registered with a CVR number. Your sole proprietorship is legally just you with a SE number (or CVR if you employ staff). Contracts, assets and liabilities must be transferred to the new company.
• Minimum share capital – An ApS requires a minimum share capital of DKK 40,000. This can be paid in cash or, under specific conditions, contributed as business assets (apportindskud) based on a valuation.
• Taxation – Profits in an ApS are taxed at the corporate tax rate of 22%. You are then taxed personally on salary (A‑income plus 8% AM‑bidrag) and on dividends. In a sole proprietorship, all profit is taxed as personal income with labour market contribution and potentially top tax.
• Accounting and reporting – An ApS must submit an annual financial statement to the Danish Business Authority (Erhvervsstyrelsen). Depending on size, it may need an audit or review. A sole proprietorship usually only submits tax information to Skattestyrelsen and has lighter formal requirements.
• Owner’s withdrawals – In a sole proprietorship you can freely withdraw funds for private use. In an ApS, money can only be taken out as salary, dividends or properly documented loans within strict rules.

Two main ways to convert: business transfer or tax‑neutral restructuring

There are two typical approaches when moving from a sole proprietorship to an ApS:

1. Simple business transfer (asset sale)
2. Tax‑neutral conversion under the Danish tax rules for business restructuring

The right method depends on your assets, accumulated profits, goodwill and long‑term plans. In both cases you must register a new ApS with Erhvervsstyrelsen and ensure that your sole proprietorship is properly closed or kept only for minor side activities if relevant.

1. Simple business transfer to a new ApS

With a simple transfer you create a new ApS and then sell or contribute the assets and activities of your sole proprietorship to the company.

Typical steps include:

1. Incorporate the ApS – Prepare the memorandum of association and articles of association, pay in at least DKK 40,000 in share capital (cash or assets) and register the company via Virk.dk. You will receive a new CVR number for the ApS.
2. Transfer assets and contracts – Move equipment, inventory, intellectual property, customer contracts and supplier agreements to the ApS. In many cases you will need written consent from counterparties to assign contracts.
3. Handle VAT and registrations – Register the ApS for VAT (moms) if your annual turnover exceeds DKK 50,000, and for A‑tax/AM‑bidrag if you will pay yourself or others a salary. Deregister VAT and employer status for the sole proprietorship once all activities are moved.
4. Close or scale down the sole proprietorship – When all operations are in the ApS, you can close the sole proprietorship via Virk.dk. You will still need to file a final tax return for the period up to closure.

A simple transfer is often easiest for smaller businesses with limited assets and no significant hidden reserves or goodwill. However, the transfer can trigger taxation of gains on assets (for example, if you sell equipment above its tax value) and on any goodwill. It is important to calculate the tax consequences before you proceed.

2. Tax‑neutral conversion to an ApS

If your sole proprietorship has built up value, goodwill or assets with unrealised gains, you may be able to convert it to an ApS on a tax‑neutral basis under the Danish rules on business restructuring (virksomhedsomdannelse). The purpose of these rules is to allow you to move the business into a company without immediate taxation of hidden gains, provided you meet specific conditions.

Key conditions typically include:

• The ApS must take over all assets and liabilities connected to the business, including any business‑related debt.
• The conversion must be done at fair market value, documented in a statement or valuation basis.
• You must receive shares in the ApS as consideration; you cannot simply receive cash for the business.
• The conversion must be reported correctly to Skattestyrelsen, including the necessary forms and statements.

In practice, a tax‑neutral conversion is more complex than a simple transfer and usually requires assistance from an accountant or tax advisor. Done correctly, it can postpone taxation of gains until you later sell the shares or withdraw profits, which can be a significant advantage for profitable, established businesses.

Practical steps to convert from sole proprietorship to ApS

Regardless of the method you choose, the conversion process usually follows these practical steps:

1. Clarify your goals and timing
   Decide whether you want a simple transfer or a tax‑neutral conversion. Consider your expected profit, risk level, financing needs and any upcoming contracts or tenders. It is often convenient to convert at the start of a new income year for clearer accounting, but this is not a legal requirement.
2. Prepare opening balance and valuation
   Prepare an opening balance sheet for the ApS showing the assets and liabilities being transferred. For tax‑neutral conversions and non‑cash contributions, you may need a valuation and, in some cases, an auditor’s statement to document the values.
3. Incorporate the ApS
   Register the ApS via Virk.dk, pay in the share capital of at least DKK 40,000 and submit the required documents. You will receive a CVR number, which you will use for VAT, tax and all business dealings.
4. Update registrations with authorities
   Register the ApS for VAT (if turnover exceeds DKK 50,000 in a 12‑month period), A‑tax and AM‑bidrag if you will pay salaries, and as an employer with Skattestyrelsen. If you have employees, transfer their employment to the ApS and update eIncome (eIndkomst) reporting.
5. Inform banks, customers and suppliers
   Open a business bank account in the name of the ApS and move your payment solutions (e.g. card terminals, online payment gateways) to the new company. Inform customers, suppliers, landlords and other partners about the new company name, CVR number and bank details, and update contracts where needed.
6. Adjust bookkeeping and invoicing
   Set up a separate accounting system for the ApS. All invoices must be issued in the name of the ApS with its CVR number and VAT registration. Keep the accounts of the sole proprietorship and the ApS clearly separated, even during the transition period.
7. Close the sole proprietorship
   Once all activities, assets and obligations are moved, deregister the sole proprietorship on Virk.dk. File your final tax return for the sole proprietorship, including any gains or adjustments resulting from the transfer.

Tax considerations when moving to an ApS

Converting to an ApS changes how your income is taxed and how you can plan your withdrawals:

• Corporate tax vs. personal tax – The ApS pays 22% corporate tax on its taxable profit. You are then taxed on salary as A‑income with 8% AM‑bidrag and personal income tax, and on dividends as share income (aktieindkomst) with progressive rates.
• Possibility to retain profits – Unlike a sole proprietorship, an ApS can retain profits in the company after paying corporate tax. This allows you to build equity, invest in growth or smooth your personal income over several years.
• Use of the business tax scheme (virksomhedsordningen) – If you currently use the business tax scheme as a sole proprietor, the conversion will affect how your interest deductions and capital are treated. The scheme does not apply in the same way once the business is in an ApS, so you should plan the transition carefully.
• Goodwill and hidden reserves – If your business has goodwill or assets with hidden gains, a simple transfer can trigger immediate tax. A tax‑neutral conversion can postpone this, but only if all conditions are met and the process is documented correctly.

Common pitfalls when converting to an ApS

Several recurring mistakes can make the conversion more expensive or complicated than necessary:

• Mixing private and company funds after the ApS is created, instead of using a proper salary or dividend policy.
• Forgetting to transfer or re‑sign key contracts, leading to legal uncertainty about who is actually the contracting party.
• Not updating VAT, A‑tax and employer registrations, which can result in incorrect reporting or penalties.
• Underestimating the tax consequences of transferring assets without a proper valuation and tax review.
• Failing to prepare the required annual report for the ApS in time, which can lead to fines or compulsory dissolution.

How a Danish accountant can help with the conversion

Because a conversion from sole proprietorship to ApS affects legal status, tax, bookkeeping and contracts at the same time, most business owners in Denmark choose to involve a professional advisor. An accountant can:

• Analyse whether and when an ApS is beneficial in your specific situation
• Calculate the tax impact of different conversion methods and choose a tax‑efficient structure
• Prepare the opening balance, valuations and required documentation for Erhvervsstyrelsen and Skattestyrelsen
• Set up the accounting system, salary routines and VAT reporting for the new ApS
• Help you close the sole proprietorship correctly and avoid double taxation or missed deductions

With proper planning, converting your Danish sole proprietorship into an ApS can significantly strengthen your legal protection, improve your tax position and support the long‑term growth of your business.
