Tax Relief for R&D Expenses in Denmark for 2026

Introduction to R&D Tax Incentives in Denmark

Denmark offers a favourable tax environment for companies that invest in research and development, and the rules for tax relief on R&D expenses are particularly relevant for businesses planning their activities for 2026. The Danish R&D tax incentive framework is designed to reduce the effective cost of innovation by allowing enhanced deductions for qualifying R&D costs and, for certain companies, a cash refund of tax losses linked to R&D activities. This makes Denmark an attractive location for both Danish and foreign-owned companies that develop new products, technologies, software or processes.

Under the Danish Corporate Tax Act, companies can generally deduct their R&D expenses at a rate of 108% of the actual qualifying costs. This means that for every DKK 100 spent on eligible R&D, the company can deduct DKK 108 from its taxable income, effectively lowering the corporate tax base. In addition, companies that are in a tax loss position can, under specific conditions, obtain a cash refund of the tax value of certain R&D-related losses, up to a statutory cap per income year.

The Danish R&D tax incentives are available to a broad range of sectors, including manufacturing, life sciences, IT and software development, green technologies, and many service industries, provided that the activities meet the definition of research and development for tax purposes. In practice, this typically covers systematic work aimed at generating new knowledge, developing or improving products, materials, processes, services or software, and resolving scientific or technological uncertainties. Routine activities, such as standard quality control, maintenance or minor cosmetic changes, are normally excluded.

From a strategic perspective, the R&D tax relief regime in Denmark serves several purposes. It encourages companies to locate high-value development functions within the country, supports start-ups and scale-ups that may not yet be profitable, and helps established groups reduce their effective tax rate on innovation-heavy projects. For international groups, the Danish rules can be integrated into a broader global R&D and IP strategy, particularly when combined with other local incentives or grant schemes.

To benefit from the available relief, companies must be able to identify, document and track their R&D projects and related costs in a structured way. This typically involves distinguishing qualifying R&D activities from non-qualifying work, allocating staff time and salaries, and capturing external costs such as subcontractors, consultants, materials, testing and prototype development. Proper documentation is essential, both for calculating the enhanced deduction and for demonstrating eligibility in the event of a tax audit.

For businesses planning their R&D budgets for 2026, it is important to understand how the Danish rules interact with corporate tax planning, group structures and potential future profitability. The timing of costs, the choice between capitalisation and expensing, and the use of loss carry-forwards or cash refunds can all influence the overall benefit. Early planning and clear internal procedures help ensure that companies capture the full value of the R&D tax incentives available under Danish law.

Overview of the Danish R&D Tax Incentive Program

The Danish R&D tax incentive program is designed to encourage companies to invest in innovation, product development and technological improvements by offering targeted tax relief on qualifying research and development expenses. It applies to a broad range of businesses operating in Denmark, from start-ups and scale-ups to large established groups, provided they carry out genuine R&D activities that aim to create new knowledge or significantly improve existing products, services or processes.

At its core, the scheme allows companies to obtain a tax benefit on eligible R&D salary costs and certain related expenses. The primary mechanism is an enhanced tax deduction for R&D costs, combined with the possibility of receiving a cash refund of negative corporate tax (tax loss) attributable to R&D activities, up to a fixed annual cap. This makes the program particularly attractive for innovative companies that are not yet profitable and therefore cannot fully use ordinary tax deductions.

Companies subject to Danish corporate income tax can generally deduct 100% of their R&D expenses as operating costs. In addition, an uplift is available on qualifying R&D salary expenses, effectively increasing the tax value of these costs compared with standard operating expenses. The enhanced deduction reduces the corporate tax base and can create or increase a tax loss that may be carried forward indefinitely or, within certain limits, converted into a cash refund.

The cash refund mechanism allows companies with tax losses generated by R&D activities to obtain a payment from the Danish tax authorities instead of waiting to offset those losses against future profits. The refund is calculated as a percentage of the negative taxable income attributable to R&D, up to a statutory ceiling per income year. This feature is especially important for early-stage and high‑growth businesses that invest heavily in development but have limited or no taxable income.

The program is administered by the Danish Tax Agency and is integrated into the ordinary corporate tax return process. There is no separate corporate tax rate for R&D income; instead, the benefit is realized through deductions, loss refunds and, in some cases, favorable treatment of development costs that would otherwise have to be capitalized. To access the incentive, companies must correctly identify and document their R&D activities and related costs in line with Danish tax rules and relevant guidance.

The Danish R&D tax incentive program is designed to be sector‑neutral and technology‑neutral. It is available to companies in manufacturing, software and IT, life sciences, green technologies, engineering, and many other industries, as long as the activities meet the definition of R&D for tax purposes. Routine improvements, standard customization and purely commercial activities are excluded, but projects that involve scientific or technological uncertainty and systematic development work can typically qualify.

In practice, the program plays a central role in Denmark’s broader innovation policy. It complements other instruments such as innovation grants and EU funding, but it is more predictable and accessible because it is embedded in the tax system. For businesses, this means that qualifying R&D costs can directly reduce the effective cost of innovation, improve cash flow and support long‑term investment in new products, services and technologies.

Qualifying R&D Activities and Eligible Costs

To benefit from tax relief for research and development in Denmark, it is essential to understand which activities qualify as R&D and which costs can be included in the tax calculation. Danish rules are broadly aligned with international standards, but they contain specific definitions and limitations that companies should consider when planning and documenting their projects.

Definition of qualifying R&D activities

For Danish tax purposes, R&D generally covers systematic activities aimed at achieving new scientific or technical knowledge, or using existing knowledge in a new way to develop or significantly improve products, services, processes or technologies. Routine work, standard production and purely commercial activities do not qualify.

In practice, qualifying R&D activities typically include:

Activities that are closely related to R&D can also qualify if they are directly connected to an eligible project. This may include planning, project management and documentation, as long as they are necessary for the execution of the R&D work and can be clearly linked to it.

Activities that are typically excluded

Not all innovation‑related work is treated as R&D for tax purposes. The following types of activities are usually excluded:

To qualify, a project should involve technical or scientific uncertainty, a structured approach (for example, defined objectives, hypotheses, tests and evaluations) and a clear link to the company’s future products, services or processes.

Eligible R&D costs

Denmark allows companies to deduct and, under certain conditions, obtain a cash refund for specific R&D costs that are directly related to qualifying activities. Only expenses that can be clearly attributed to R&D projects are eligible; general overheads and non‑R&D costs must be excluded or allocated on a reasonable basis.

The main categories of eligible costs include:

1. Salaries and related staff costs

Personnel expenses are typically the largest component of R&D costs. Eligible costs include:

If an employee works partly on R&D and partly on other tasks, only the proportion of time spent on qualifying R&D can be included. Companies should maintain time sheets or other reliable documentation to support the allocation.

2. External consultants and subcontractors

Fees paid to external experts, consultants and subcontractors can be eligible when the work they perform is directly related to the company’s R&D projects. This may cover:

Only the R&D‑related part of the external services can be included. Invoices and contracts should clearly describe the nature of the work and its link to the R&D project.

3. Materials, components and consumables

Costs of materials and consumables used in R&D projects are generally eligible, for example:

Where materials are used partly for R&D and partly for commercial production, companies must allocate the costs based on documented consumption or a reasonable, consistent method.

4. Equipment and depreciation

Investments in machinery, laboratory equipment, testing devices and IT hardware used in R&D can be included through tax depreciation. The eligible amount is the tax‑deductible depreciation for the period that relates to R&D use.

If an asset is used both for R&D and for normal operations, only the R&D‑related share of the depreciation can be treated as an R&D cost. Companies should document the allocation, for example by using usage statistics, capacity calculations or other objective criteria.

5. Software and IT costs

Software and IT expenses can qualify when they are directly connected to R&D projects, such as:

Standard office software, general IT support and routine maintenance are normally not considered R&D costs unless they are clearly and directly linked to qualifying activities.

6. Testing, trials and pilot production

Expenses related to testing and experimental production can be eligible when they are part of the R&D process, including:

Once a product or process has reached stable commercial production, subsequent routine testing and quality control are no longer treated as R&D.

7. Collaboration with universities and research institutions

Payments to Danish or foreign universities, GTS institutes and other research organisations can be included when they relate to the company’s own R&D projects. This may cover:

Only the part of the contribution that finances activities meeting the R&D criteria can be treated as an eligible cost.

Costs that are generally not eligible

Certain expenses are typically excluded from the Danish R&D tax relief, even if they are incurred in connection with innovative projects. These include:

Direct link and documentation

To treat an expense as an eligible R&D cost, the company must be able to demonstrate a clear and direct link between the cost and specific R&D activities. In practice, this requires:

Careful classification of activities and costs not only reduces the risk of disputes with the tax authorities but also ensures that the company makes full use of the available R&D tax relief in Denmark.

SkatteFUNN: The Primary R&D Tax Credit Mechanism

In Denmark, the main framework for tax relief on research and development costs is the Danish R&D tax deduction and cash refund scheme, which functions as the primary R&D tax credit mechanism. It allows companies to obtain an enhanced tax deduction for qualifying R&D expenses and, under specific conditions, a cash refund of tax losses related to R&D. This mechanism is designed to support both start-ups and established businesses that invest in innovation, product development and technological improvements.

The scheme applies to companies subject to Danish corporate taxation, regardless of size or industry, as long as they carry out qualifying R&D activities. Both Danish companies and Danish permanent establishments of foreign companies can benefit. The incentive is particularly relevant for businesses that are not yet profitable, as they may receive a cash refund instead of waiting to offset R&D costs against future taxable income.

Under the current rules, companies can obtain an uplift on their qualifying R&D expenses through an increased tax deduction. In practice, this means that eligible R&D costs are deducted at a rate higher than 100% when calculating taxable income. The effective corporate tax rate in Denmark is 22%, so the additional deduction translates into a concrete tax saving on top of the ordinary cost deduction already recognized in the accounts.

A key feature of the Danish mechanism is the possibility of converting tax losses attributable to R&D into a cash refund. If a company reports a tax loss for the year and part of this loss is generated by qualifying R&D expenses, it may apply for a refund of the tax value of that R&D-related loss. The refund is calculated using the 22% corporate tax rate and is subject to an annual cap per company or per tax group. This cap limits the maximum amount that can be refunded in a single income year, but unused R&D losses above the cap can typically be carried forward for use in future years.

The mechanism covers a broad range of R&D-related costs, including salaries for employees directly engaged in research and development, employer-paid social security contributions on those salaries, materials and consumables used in R&D projects, as well as certain external consultancy and subcontractor costs. To be eligible, the activities must be systematic, innovative and aimed at generating new knowledge, products, processes or services, or at significantly improving existing ones. Routine product updates, standard quality control or purely commercial activities do not qualify.

From a practical perspective, the R&D tax mechanism is integrated into the ordinary corporate tax return. Companies identify and document their qualifying R&D costs during the financial year, allocate them correctly in the tax computation and then indicate in the return whether they wish to claim a cash refund of R&D-related tax losses. The Danish Tax Agency may request supporting documentation, so it is important to maintain clear project descriptions, time records for R&D staff, and evidence of how costs have been allocated between R&D and non-R&D activities.

For many businesses, the Danish R&D tax mechanism functions as a predictable and relatively straightforward way to reduce the net cost of innovation. Profitable companies benefit from a lower effective tax burden, while loss-making or early-stage companies can improve liquidity through cash refunds. At the same time, the scheme is subject to specific definitions, caps and documentation requirements, which means that careful planning and accurate classification of activities are essential to secure the full benefit and to withstand potential tax audits.

How the R&D Tax Credit Operates in Denmark

The Danish R&D tax relief is designed as an enhanced deduction and, in certain cases, a cash refund of tax losses. In practice, this means that qualifying research and development expenses can reduce a company’s taxable income more than ordinary operating costs, and for loss-making companies a portion of the tax value of these losses can be paid out in cash.

Companies that carry out eligible R&D activities can generally deduct their R&D expenses at up to 130% of the actual cost for corporate income tax purposes, provided that the activities meet the Danish definition of research and development and are properly documented. This enhanced deduction is applied in the annual corporate tax return and reduces the taxable profit on which the standard Danish corporate income tax rate of 22% is levied.

If the company is in a tax loss position after applying the enhanced deduction, it may be entitled to a cash refund of the tax value of part of the R&D-related loss. The refund is calculated using the 22% corporate tax rate and is subject to an annual cap on the amount of loss that can be converted into a refund. Any remaining losses that exceed this cap are carried forward under the general Danish loss carry-forward rules and can be used to offset future taxable profits.

The tax credit mechanism operates on an annual basis and is claimed through the ordinary tax filing with the Danish Tax Agency. The company identifies its qualifying R&D costs for the income year, applies the enhanced deduction in the tax computation, and then determines whether it is in a taxable profit or loss position. If a loss arises and the conditions for a refund are met, the company can request the cash payment as part of the same filing process.

The relief is available to Danish companies and Danish permanent establishments of foreign entities that are subject to Danish corporate income tax. It applies to both in-house R&D and certain outsourced activities, as long as the company bears the economic risk and retains the rights to the results. The scheme is neutral with respect to industry and company size, so both start-ups and large corporations can benefit, although the cash refund feature is particularly important for early-stage and growth companies that do not yet generate taxable profits.

In practice, the effectiveness of the R&D tax credit depends on accurate identification and allocation of qualifying costs. Companies must distinguish between R&D expenses that are eligible for the enhanced deduction and routine operational costs that are not. Typical qualifying costs include salaries of employees directly engaged in R&D, consumables, certain subcontractor costs and depreciation of equipment used in research and development. These costs are aggregated and then multiplied by the applicable enhancement factor to determine the total deductible amount.

The Danish system is integrated with the broader corporate tax framework, so the R&D tax credit does not operate as a separate grant or subsidy, but as a targeted adjustment to the tax base and, where relevant, a refund of the tax value of R&D-related losses. This structure makes the incentive predictable and relatively straightforward to administer, provided that companies maintain clear documentation, project descriptions and cost breakdowns to support their claims in the event of a tax audit.

Application Process and Documentation Requirements

The Danish R&D tax relief regime is designed to be accessible, but it requires careful planning, clear internal processes and robust documentation. A well-prepared application not only increases the likelihood of obtaining the tax benefit, it also reduces the risk of adjustments during a tax audit. Below is an overview of how the process typically works and which documents companies should have in place.

Step-by-step application process

In Denmark, R&D tax relief is normally claimed through the corporate tax return rather than via a separate stand‑alone application. However, companies must actively identify and calculate their qualifying R&D costs and, where relevant, apply for a cash refund of R&D tax losses.

  1. Identify qualifying R&D projects
    The first step is to determine which activities meet the Danish definition of research and development. This typically includes systematic work aimed at acquiring new knowledge, developing new products, processes or services, or significantly improving existing ones. Companies should map their projects and separate routine activities (such as standard quality control or maintenance) from genuine R&D.
  2. Classify eligible costs
    Once the projects are identified, the company must classify the related expenses. Typical cost categories include salaries and social security for employees directly involved in R&D, depreciation of R&D equipment, materials and consumables used in experiments, and a proportion of overheads that can be clearly allocated to R&D. Only costs that can be directly linked to qualifying projects should be included in the calculation.
  3. Calculate the R&D tax relief
    The Danish rules allow an additional tax deduction (uplift) on qualifying R&D expenses within specified limits, as well as the possibility to obtain a cash refund of tax losses related to R&D up to a statutory cap per income year. Companies must calculate:
    • the total amount of qualifying R&D expenditure for the income year
    • the additional deduction or uplift percentage applicable to those costs
    • the part of the tax loss that can be converted into a cash refund, subject to the annual ceiling
  4. Report R&D in the corporate tax return
    The R&D tax relief is claimed in the Danish corporate income tax return (selvangivelse). Specific fields are used to report:
    • the total qualifying R&D expenses
    • the calculated additional deduction
    • the amount of tax loss for which a cash refund is requested
    The tax return is filed electronically via the Danish Tax Agency’s (Skattestyrelsen) online system. The R&D figures must be consistent with the company’s statutory accounts and internal project records.
  5. Submit any required supplementary information
    While the tax relief is claimed through the tax return, the Danish Tax Agency may request additional documentation or explanations, especially for larger claims. Companies should be prepared to provide project descriptions, calculations and supporting schedules promptly if asked.
  6. Follow up on assessment and possible audit
    After filing, the tax authorities review the return and may raise questions or open a targeted audit of the R&D claim. A clear audit trail and well‑structured documentation significantly reduce the time and effort required to respond and help secure the benefit without major adjustments.

Key documentation requirements

There is no single mandatory template for R&D documentation in Denmark, but the tax authorities expect companies to maintain detailed, contemporaneous records that demonstrate both the nature of the activities and the associated costs. At a minimum, businesses should be able to present the following.

Project-level documentation

Cost and time-tracking documentation

Internal policies and control framework

To ensure consistency and reduce the risk of disputes, many Danish companies implement internal R&D policies and controls. While not legally required, such documents are highly recommended and can be valuable during a tax audit.

Common pitfalls to avoid

Several recurring issues can weaken an R&D tax relief claim in Denmark. Being aware of them helps companies prepare stronger applications.

Practical recommendations for businesses

To make the application process smoother and to maximise the benefit of Danish R&D tax relief, companies should consider the following practical steps:

With a structured approach to the application process and well‑organised documentation, companies operating in Denmark can claim R&D tax relief with greater confidence and reduce the risk of future disputes with the tax authorities.

Deadlines and Filing Procedures for R&D Tax Relief

Claiming tax relief for research and development expenses in Denmark follows the ordinary corporate tax return cycle, but there are specific deadlines and procedural steps that companies must respect to secure the benefit and avoid losing the right to a refund or deduction.

Key deadlines for claiming R&D tax relief

R&D tax relief is claimed as part of the annual corporate tax return (selvangivelse). For companies with a standard financial year that follows the calendar year, the main deadlines are:

Companies with non-calendar financial years must apply the same rules, counting the 6‑month deadline from the end of their specific income year and observing the absolute latest filing date set by the Danish tax authorities for that year.

Filing procedures for R&D tax relief

R&D tax relief is not claimed through a separate stand‑alone form, but through specific sections of the electronic corporate tax return submitted via TastSelv Erhverv. The process typically involves:

  1. Identifying and calculating the total eligible R&D expenses for the income year, including salaries, external consulting, materials and other qualifying costs.
  2. Entering the eligible R&D expenses in the designated fields of the corporate tax return, ensuring that the amounts correspond to the figures in the statutory financial statements and internal project records.
  3. Indicating whether the company wishes to:
    • Use the R&D deduction to reduce taxable income, or
    • Request a cash refund of the tax value of R&D‑related tax losses, up to the maximum amount allowed under current rules.
  4. Submitting the tax return electronically within the statutory deadline and retaining proof of submission.

For groups, each Danish group company must file its own tax return and R&D claim, unless they are part of a joint taxation scheme where the administrative company coordinates the filing. In such cases, the R&D relief is still calculated per company, but the effect is reflected in the joint tax computation.

Documentation and record‑keeping expectations

Although supporting documentation is not always submitted together with the tax return, the Danish Tax Agency can request detailed information and evidence at any time during or after the assessment process. Companies should therefore maintain:

These records should be kept for at least the standard Danish tax documentation period, so they are available in case of a tax audit or subsequent review of the R&D claim.

Corrections, amendments and late filings

If errors are discovered after filing, companies can usually correct their R&D claim by submitting an amended tax return within the general reassessment period. However, the ability to obtain a cash refund for a past year may be limited if the original return was filed late or if the statutory deadline for making the refund election has passed.

Late filing can lead to the loss of the right to a cash refund for that year, even if the company is still allowed to deduct R&D expenses in the tax computation. Penalties or interest may also apply to late or incorrect filings. It is therefore important to:

By respecting the Danish filing deadlines and following the formal procedures, companies can fully benefit from the available R&D tax relief and reduce the risk of disputes with the tax authorities.

Advantages and Limitations for Businesses

The Danish R&D tax relief scheme offers a number of strategic advantages for companies investing in innovation, but it also comes with practical limitations that businesses should understand before planning their projects and budgets.

Key advantages of the Danish R&D tax relief

One of the most important benefits is the possibility to obtain a cash refund for R&D-related tax losses. Companies that generate a tax loss due to deductible R&D costs can request a refund of the tax value of these losses, up to a capped amount per income year. This improves liquidity for research-intensive businesses and start-ups that may not yet be profitable.

R&D expenses that qualify under Danish tax rules are generally fully deductible when incurred. This means that salaries, materials, external consultancy, and other directly related R&D costs can reduce the taxable income in the year the expenses arise, rather than being capitalised and depreciated over several years. For profitable companies, this provides an immediate reduction of the corporate tax base at the standard corporate income tax rate.

The regime is also designed to be sector-neutral. Both manufacturing and service companies, including software, life sciences, green technology, engineering, and design-intensive industries, can benefit as long as the activities meet the definition of R&D for tax purposes. This makes the scheme attractive for a broad range of Danish and foreign-owned entities operating in Denmark.

Another advantage is the alignment with international R&D standards. The Danish definition of R&D is closely inspired by the OECD Frascati Manual, which many multinational groups already use as an internal benchmark. This helps global companies integrate Danish R&D tax planning into their broader international tax and transfer pricing strategies.

From a strategic perspective, the tax relief can improve the internal rate of return on innovation projects and support long-term investment decisions. When modelled correctly, the expected tax benefit can be factored into project budgets, making it easier to justify higher-risk or more exploratory R&D initiatives. For small and medium-sized enterprises, the combination of immediate deductibility and potential cash refund can be a critical source of non-dilutive financing.

Limitations and practical constraints

Despite these benefits, there are several limitations that businesses must consider. First, only activities that qualify as genuine research or development under Danish tax law are eligible. Routine engineering, standard software implementation, maintenance, quality control, and minor product adaptations typically do not qualify. Companies must be able to demonstrate that the work involves a systematic effort to achieve scientific or technological advancement or to resolve scientific or technological uncertainty.

The scope of eligible costs is also restricted. While direct R&D salaries, employer social security contributions, materials, and certain external services can be included, general overheads, marketing, sales activities, and non-R&D administrative costs are excluded. Allocation of shared costs between R&D and non-R&D functions must be reasonable and well documented, which can be administratively demanding for organisations with complex structures.

There is a monetary cap on the amount of R&D-related tax loss that can be converted into a cash refund each year. If a company’s R&D expenses generate tax losses exceeding this ceiling, the excess can still be carried forward as tax losses to offset future taxable income, but will not trigger an immediate cash refund. This particularly affects large research-intensive groups with substantial annual R&D budgets.

Another limitation is the strict documentation requirement. To support a claim, companies must maintain detailed project descriptions, technical documentation, time records for R&D staff, cost breakdowns, and internal approvals. The Danish Tax Agency can request this information during a review or audit, and insufficient documentation may lead to partial or full denial of the benefit. For many businesses, setting up and maintaining such documentation systems requires additional internal resources or external advisory support.

Timing is also a constraint. Claims for R&D tax relief must be aligned with the corporate income tax return and relevant statutory deadlines. Late or incomplete filings can limit access to the scheme or delay the benefit. For groups with multiple Danish entities or cross-border projects, coordinating data collection and filing across departments and jurisdictions can be challenging.

Finally, the regime is subject to ongoing political and regulatory scrutiny. While Denmark is generally supportive of innovation incentives, changes to caps, definitions, or administrative practice can occur. Companies that rely heavily on R&D tax relief as part of their long-term financing strategy should regularly monitor legislative developments and reassess the financial impact on their project pipeline.

Balancing benefits and constraints in practice

In practice, the advantages of the Danish R&D tax relief are most fully realised when companies treat it as an integrated part of their financial and project management processes. This typically involves identifying qualifying activities at an early stage, tracking eligible costs in real time, and ensuring that technical and financial documentation is aligned.

For smaller companies and start-ups, the main value often lies in the liquidity effect of the cash refund and the ability to reinvest the tax benefit directly into further development. For larger groups, the focus is more often on optimising the overall effective tax rate, managing risk in relation to tax audits, and coordinating Danish R&D incentives with other national regimes.

Understanding both the strengths and the limitations of the Danish R&D tax relief allows businesses to make informed decisions, avoid common pitfalls, and structure their innovation activities in a way that maximises the available tax support while remaining compliant with current regulations.

Real-Life Examples and Case Studies

Understanding how the Danish R&D tax relief works in practice is often easier when you look at concrete business scenarios. Below are illustrative examples of how different types of companies can benefit from the R&D uplift deduction and the cash refund mechanism for R&D-related tax losses.

1. Tech start-up developing a software platform

A small Danish start-up is building a cloud-based platform that uses machine learning to optimise logistics routes. The company has no taxable profit yet, but it incurs significant R&D expenses during the income year.

Its qualifying R&D costs include salaries for developers and data scientists, employer social security contributions, cloud infrastructure directly used for development and testing, and external consultancy for algorithm design. The total eligible R&D expenditure for the year amounts to DKK 2,000,000.

The Danish rules allow an uplift of 130% on qualifying R&D costs. This means the company can deduct DKK 2,600,000 (130% of DKK 2,000,000) when calculating its taxable income. Because the company is loss-making, it can apply for a cash refund of the tax value of the R&D-related loss, up to the statutory ceiling of DKK 25,000,000 of R&D costs per year at the 130% rate.

Assuming the corporate income tax rate of 22%, the tax value of the uplifted R&D deduction is DKK 572,000 (22% of DKK 2,600,000). The company applies for a refund of this amount together with its corporate tax return. The refund improves cash flow and helps finance further development without diluting ownership through additional equity rounds.

2. Manufacturing company upgrading production technology

A medium-sized manufacturing business in Denmark produces specialised components for the wind energy sector. To remain competitive, it launches an R&D project to develop a new production line using advanced robotics and sensors to reduce material waste and increase precision.

The project lasts two years and involves engineers, technicians and external research partners. Qualifying R&D costs include a portion of salaries for the internal project team, depreciation of test equipment used exclusively for development, materials consumed in test runs and fees paid to a Danish technical university for collaborative research. For the current income year, the company identifies DKK 8,000,000 of eligible R&D expenditure.

With the 130% uplift, the deductible amount becomes DKK 10,400,000. If the company’s accounting profit before tax is DKK 12,000,000, the enhanced deduction reduces its taxable income to DKK 9,600,000. At a 22% corporate tax rate, this results in a tax saving of DKK 572,000 compared with a standard 100% deduction (where the tax saving would have been DKK 1,760,000 instead of DKK 2,288,000).

The company does not receive a cash refund because it is profitable, but the reduced tax bill effectively co-finances the R&D project. The savings are reinvested into expanding the new production line and training staff in the new technology.

3. Life science company collaborating with universities

A Danish life science company is working on a new medical device that requires extensive clinical testing and regulatory documentation. The project is carried out in collaboration with two Nordic hospitals and a Danish university.

Eligible R&D costs include salaries for the internal R&D team, payments to hospitals for clinical trials, fees for regulatory consulting directly related to the development phase, and costs of prototypes and testing. Over the income year, the company incurs DKK 15,000,000 in qualifying R&D expenditure.

Applying the 130% uplift, the company can deduct DKK 19,500,000 for tax purposes. Because the company is still in a heavy investment phase and records a tax loss, it chooses to request a cash refund of the tax value of the R&D-related loss. At 22%, the potential refund on the uplifted R&D amount is DKK 4,290,000, subject to the annual cap for refundable R&D costs.

This refund significantly reduces the net cost of clinical trials and accelerates the path to market. The company uses the additional liquidity to expand its R&D team and initiate a follow-up project on next-generation device features.

4. SME in the green energy sector

A small and medium-sized enterprise in the green energy sector develops an innovative control system for optimising energy consumption in commercial buildings. The project combines hardware sensors with proprietary control algorithms.

The company carefully separates routine engineering and customisation work from genuine R&D activities that involve technological uncertainty and systematic experimentation. After this analysis, it identifies DKK 3,500,000 of costs that meet the Danish definition of R&D, including a share of engineers’ salaries, prototype components, testing facilities and specialised software licences used solely for development.

With the 130% uplift, the deductible amount is DKK 4,550,000. The company has modest profits from existing products, so the enhanced deduction reduces its taxable income and lowers its corporate tax liability. The effective tax saving on the uplift portion (the extra 30%) is DKK 231,000 (22% of DKK 1,050,000), which the company factors into its project budgeting as a predictable source of indirect funding.

Key lessons from the examples

These scenarios highlight several practical points for businesses considering R&D tax relief in Denmark:

By structuring projects and internal records with the R&D rules in mind, companies can turn the Danish tax relief into a stable and predictable part of their innovation financing mix.

Frequently Asked Questions about R&D Tax Incentives

Below you will find answers to the most common questions businesses ask about tax relief for R&D expenses in Denmark. The information applies to companies subject to Danish corporate taxation that carry out genuine research and development activities.

Which companies can claim R&D tax relief in Denmark?

Any company that is fully or limited tax liable in Denmark and carries out qualifying R&D activities can claim R&D tax relief. This includes Danish limited companies (A/S, ApS), branches of foreign companies, and certain partnerships where partners are taxed as companies. Sole proprietors and individuals can also benefit from R&D deductions, but the rules and practical impact differ from corporate taxpayers.

What is the main form of R&D tax relief in Denmark?

The primary mechanism is an enhanced tax deduction for R&D expenses. Companies can deduct more than 100% of their qualifying R&D costs when calculating taxable income, up to a statutory maximum percentage set in the Danish Tax Assessment Act. In addition, loss-making companies can apply for a cash refund of a portion of their tax value of R&D-related losses, subject to an annual cap.

What types of activities qualify as R&D?

Qualifying R&D activities generally include systematic work aimed at acquiring new knowledge, developing new products, processes or services, or significantly improving existing ones. This typically covers:

Routine quality control, market research, sales activities, and standard software implementation without technological innovation do not qualify as R&D.

Which costs are eligible for R&D tax relief?

Eligible costs usually include:

Costs must be directly connected to qualifying R&D projects and properly documented. General administrative expenses, marketing costs and non-R&D travel are normally excluded.

How does the enhanced R&D deduction work in practice?

R&D expenses are first identified and documented. When filing the corporate tax return, the company applies the enhanced deduction rate to the qualifying cost base. The result is a higher deductible amount than the actual expenses incurred, which reduces taxable income and therefore corporate tax payable. The exact enhancement percentage and any applicable ceilings are defined in Danish tax law and apply uniformly to all eligible taxpayers.

Can loss-making companies benefit from R&D tax relief?

Yes. If a company reports a tax loss after applying the R&D deduction, it may be entitled to a cash refund of the tax value of part of that loss attributable to R&D. The refund is calculated using the standard corporate tax rate and is subject to an annual monetary cap per company or group. Any remaining loss that is not refunded can normally be carried forward for offset against future taxable profits.

Is there a minimum or maximum amount of R&D expenses required?

There is no statutory minimum threshold for claiming the enhanced R&D deduction, so even smaller projects can qualify if they meet the R&D criteria. However, the cash refund for loss-making companies is limited by an annual cap on the tax base eligible for refund. Once that ceiling is reached, additional R&D losses can still be carried forward but will not generate a cash refund for the year.

Do subcontracted or outsourced R&D activities qualify?

Subcontracted R&D can qualify if the Danish company bears the financial risk, owns or co-owns the results, and the work meets the definition of R&D. Payments to Danish or foreign research institutions, universities or specialist R&D providers may be included in the eligible cost base, provided the services are directly linked to the company’s R&D projects and properly documented by contracts and invoices.

How should companies document their R&D activities?

Documentation is essential. Companies should maintain:

Good documentation makes it easier to substantiate the R&D claim in case of a tax audit.

When and how is the R&D tax relief claimed?

The R&D deduction and any cash refund are claimed through the annual corporate tax return filed with the Danish Tax Agency. R&D-related fields and schedules must be completed with the total qualifying cost base and the calculated enhanced deduction or refund. Claims must be submitted within the general filing deadlines for corporate tax, and corrections are possible within the standard reassessment period if errors are discovered later.

Can companies revise previous years’ R&D claims?

Yes, companies can usually request a reassessment of previous tax years if they identify additional qualifying R&D costs or corrections. This must be done within the statutory limitation period for tax reassessments. The Danish Tax Agency may ask for detailed documentation for the years in question, so it is important to keep R&D records for the entire limitation period.

Is prior approval from the Danish Tax Agency required?

In most cases, companies claim R&D tax relief directly in their tax return without prior approval. However, the tax authorities have the right to review and challenge the classification of activities and costs during audits. For complex or borderline projects, many businesses choose to seek professional advice or obtain advance guidance to reduce the risk of disputes.

How do R&D tax incentives interact with other public support schemes?

R&D tax relief can often be combined with other forms of public support, such as innovation grants or subsidies, but double funding of the same cost item is not allowed. If a project receives non-repayable public funding, the subsidised portion of the costs may need to be excluded from the R&D tax base or adjusted to comply with state aid rules. Companies should carefully review the conditions of each support scheme.

What are the main risks and common mistakes?

Common issues include:

Careful project scoping, robust documentation and coordination between finance and technical teams help minimise these risks.

Where can businesses get help with R&D tax incentives in Denmark?

Companies can consult the official guidance from the Danish Tax Agency, speak with their regular accountant, or engage specialised advisors with experience in Danish R&D tax rules. Professional support can be particularly valuable for identifying all eligible projects and costs, structuring documentation, and managing dialogue with the tax authorities.
