Denmark Researcher Tax Scheme Guide (27% Flat Tax for Researchers)

What Is the Researcher Tax Scheme

The researcher tax scheme (forskerskatteordningen) is a special tax arrangement for foreign researchers and key employees working in Denmark. Instead of being taxed under the standard progressive Danish income tax system (where marginal rates can reach 52% including AM-bidrag), qualifying individuals pay a flat 27% A-skat rate on their gross salary. The 8% AM-bidrag (labour market contribution) is not applied, making the effective total tax rate 27% of the gross salary rather than the standard 38–52% that would otherwise apply to a similar income level.

The scheme was introduced in the early 2000s to help Denmark compete internationally for top talent in research, technology, and business. It has been revised several times — the most recent significant change was an extension of the maximum duration from 5 years to 7 years (effective 2021), and adjustments to the salary threshold to reflect inflation. The scheme is a simplified taxation — participants generally cannot claim personal deductions (interest expenses, commuting costs, trade union fees, etc.) during the scheme period, as the 27% rate is intended to be a final and comprehensive tax on salary income. However, there are limited exceptions for certain deductions (e.g., negative interest income can be carried forward for use after the scheme ends). The scheme does not cover share income, capital gains, or investment income — these are taxed under the standard rules (27/42% for shares, capital gains at 27–42%, and interest at standard rates). The 27% rate applies only to salary from the qualifying employment. For a broader overview of Danish personal taxation, see our Personal Tax Guide →.

Eligibility Requirements

To qualify for the researcher tax scheme, an individual must meet both the salary threshold and the functional criteria (researcher or key employee). The requirements are strictly applied by SKAT, and the burden of proof is on the employer and employee.

Minimum salary threshold: The employee's gross annual salary must be at least approximately 858,000 DKK in 2026 (updated annually — equivalent to ~71,500 DKK per month). This includes base salary, fixed bonuses, pension contributions paid by the employer (if included as part of the total salary package), and other guaranteed remuneration. It does not include variable bonuses tied to performance targets (unless guaranteed), non-cash benefits (company car, free phone), or reimbursement of expenses. The salary must be at arm's length — if you are an owner-manager or related to the employer, SKAT will scrutinize the salary level to ensure it reflects market value for the role. The threshold is adjusted each year by SKAT based on the Danish salary index. If the salary falls below the threshold during the scheme period (e.g., due to reduced hours), the scheme may be revoked for future months.

Researcher qualification: To qualify as a researcher, the individual must hold a position that requires PhD-level qualifications or equivalent research experience. The position must involve original research, development, or innovation. Acceptable documentation includes a PhD certificate, publication record, and a job description demonstrating research responsibilities. Universities, research institutions, and R&D departments of private companies commonly use this track. The research must be the primary function of the position — administrative or teaching roles that include some research may not qualify unless research is the main purpose.

Key employee qualification: To qualify as a key employee, the individual must have specialist knowledge and decision-making power that is not readily available in the Danish labour market. This category covers senior executives, technical specialists, and experts in fields where Denmark has a talent shortage. The key employee track requires: a high-level position (e.g., director, head of department, senior engineer, lead scientist), specialist knowledge acquired through extensive education or experience (typically 5+ years in the field), and a salary significantly above market average for the sector. SKAT assesses whether the person's skills and responsibilities justify the key employee designation. Simply having a high salary is not sufficient — the functional criteria must be met.

Not available for previous residents: The scheme is not available to individuals who have been resident in Denmark for 10 years or more before the employment start date. This prevents Danish residents from leaving and returning to claim the scheme. If you have lived in Denmark before but relocated abroad, you may become eligible after 10 years of non-residence. The 10-year period is calculated from the date of departure from Denmark to the date of the new employment start. For more on moving to Denmark, see our Moving to Denmark Tax Guide →.

Application Process

The application for the researcher tax scheme is initiated by the employer, not the employee. The employer must submit the application to SKAT before or at the start of the employment. Timing is critical — the scheme can only apply from the first day of employment, and you cannot apply retroactively.

Documentation required: The employer must submit the following to SKAT: a completed application form (available on skat.dk under the researcher scheme section), a detailed job description outlining the employee's duties, responsibilities, and research/specialist content, documentation of the employee's qualifications (PhD certificate, degree certificates, CV, publication list for researchers; CV and experience documentation for key employees), the employment contract showing salary, benefits, and working hours, and documentation of the salary level confirming it meets the threshold. For key employees, additional documentation of specialist knowledge and decision-making authority is required (e.g., organisational charts, budget responsibility, strategic role descriptions). All documentation must be in Danish or English. Translations may be required for certificates in other languages.

SKAT processing and timeline: SKAT aims to process applications within approximately 30 days of receiving a complete application. However, complex cases or applications with missing documentation can take significantly longer (up to 3 months). You can check the application status through SKAT's business portal using MitID Erhverv. If SKAT approves the application, the approval is valid from the first day of employment (provided the application was submitted before or on the start date). If the application is submitted after the start date, the scheme applies from the date of submission, not retroactively. If SKAT rejects the application, you can appeal within 4 weeks. The appeal is first considered by SKAT, then by the Tax Agency (Skattestyrelsen), and ultimately by the Tax Appeals Board (Skatterådet). Given the potential tax savings (up to ~200,000 DKK/year or more for high earners), professional advice is recommended for complex applications.

Tax Treatment Under the Scheme

The tax treatment under the researcher scheme differs significantly from standard Danish taxation. Understanding these differences is important for financial planning during the scheme period.

27% flat rate on all salary: Under the scheme, all salary from the qualifying employment is taxed at a flat 27% A-skat rate. The employer withholds this amount through the normal eIndkomst system using a special tax card code. The 27% rate applies to all salary components: base salary, bonuses (if paid by the same employer), holiday pay, and any other cash remuneration. The rate is applied before any other deductions or adjustments. The employee receives their salary net of 27% — this is a significant improvement over the standard rate of 38–52% for high earners. For example, on a salary of 100,000 DKK/month, the standard tax would be approximately 42,000 DKK (including AM-bidrag), while under the scheme it is 27,000 DKK — a saving of 15,000 DKK/month or 180,000 DKK/year.

No AM-bidrag: The 8% AM-bidrag (labour market contribution) is not applied to salary under the researcher scheme. This is one of the key benefits — the combined standard rate of 38–52% includes 8% AM-bidrag plus income tax of 30–44%, while the scheme replaces both with a single 27% rate. The employer does not report or pay AM-bidrag on salary covered by the scheme. Note that the employer's AM-bidrag (arbejdsgiverens AM-bidrag) may still apply — check with your employer.

No personal deductions during scheme: Participants in the researcher scheme generally cannot claim personal deductions against their salary income for the duration of the scheme. This includes: interest expenses (negative net interest), commuting costs (kørselsfradrag), trade union fees (fagforeningskontingent), unemployment insurance (A-kasse), and charitable donations. However, certain deductions can be carried forward for use after the scheme ends. For example, if you have negative net interest income (mortgage interest exceeding investment income), the unused deduction can be carried forward and used against future income. The limitation on deductions is one of the trade-offs of the simplified 27% rate. Investment income (dividends, capital gains, interest income) is taxed under the normal rules (27/42% for shares, standard rates for interest) and is not covered by the scheme.

Pension contributions: Employer pension contributions made during the scheme period are taxable in Denmark under the scheme — they are included in the salary subject to 27% tax. This is different from the standard treatment where employer pension contributions are not taxable until payout. Under the scheme, the pension contributions are taxed upfront at 27%, and the pension payout in retirement may be tax-free in Denmark (depending on the type of pension scheme and treaty). This can be beneficial if the employee plans to leave Denmark before retirement (since the pension fund can be transferred abroad without additional Danish tax). For more on cross-border pensions, see our Pension Tax Guide →.

Duration and Extension

The researcher tax scheme is available for a maximum of 7 years total per individual. Understanding the duration rules is important for long-term planning.

Maximum 7 years total: The scheme can apply for a maximum of 84 months (7 years) of employment. The period does not need to be continuous — you can use part of the 7 years with one employer and the remainder with another (provided the new employment also qualifies). Once the 7 years are used, you cannot re-enter the scheme, even after a period of non-residence in Denmark. The 7-year limit is calculated from the first day the scheme applies, not from the start of employment in Denmark. If you switch employers during the scheme period, the clock continues running — you cannot reset the 7-year limit by changing jobs.

Breaks in employment: Short breaks between employments (e.g., 1–3 months) do not stop the scheme clock entirely, but the months of break are not counted against the 7 years. For example, if you work under the scheme for 3 years, take a 6-month break (not working for a Danish employer), and then start a new qualifying job, you have 4 years of scheme remaining. However, if you take a long break (more than 12 months), SKAT may consider that the original approval has lapsed, and you may need to reapply. The new employer must initiate a new application for the remaining scheme period.

Going from scheme to normal taxation after expiry: Once the 7-year period expires, the employee transitions to the standard Danish progressive tax system. This means the tax rate increases from 27% to approximately 38–52% (depending on income level). This is a significant jump that should be factored into financial planning. Some employers offer tax equalization or salary adjustments to mitigate the impact. After the scheme expires, the employee becomes eligible for deductions that were not available during the scheme period (interest deductions, commuting costs, etc.). Any unused carry-forward deductions (e.g., negative net interest) can be applied starting from the first year after the scheme ends. For more on standard personal taxation, see our Personal Tax Guide →.

Interaction with Entry and Exit Taxation

The researcher scheme affects how certain entry and exit tax rules apply. Understanding these interactions is important for individuals moving to and from Denmark.

Entry — assets brought to Denmark: When moving to Denmark, you can request a binding ruling (bindende svar) from SKAT on the valuation of assets brought into the country. This is particularly relevant for capital assets (shares, crypto, investment portfolios) that will be subject to Danish exit tax rules when you leave Denmark. The binding ruling provides certainty on the tax base for future exit tax calculations. The researcher scheme does not provide any special exemption from the standard entry tax rules — you are subject to the same rules as any other individual moving to Denmark. For a detailed guide on moving to Denmark, see our Moving to Denmark Tax Guide →.

Exit — tax on departure: When you leave Denmark (after the scheme expires or earlier), you are subject to the standard exit tax rules (afståelsesbeskatning). This means that shares, crypto assets, and certain other assets are deemed to be realised at the time of departure, and you must pay Danish tax on the unrealised gains. The researcher scheme does not provide any special exit tax benefits — the exit tax is calculated under the normal rules. However, you can apply for deferred payment of the exit tax (up to 14 years in some cases) by providing security. You may also be able to reclaim Danish withholding tax on dividends and interest paid to you after departure, under the applicable double taxation treaty. The 27% tax paid under the scheme is final — you cannot reclaim any portion of it upon leaving Denmark. For more on exit tax, see our Moving to Denmark Tax Guide →.

FAQs

What is the 27% researcher tax scheme in Denmark?

It is a special tax arrangement for foreign researchers and key employees that provides a flat 27% tax rate on salary income, with no AM-bidrag (8% labour market contribution). It replaces the standard progressive system (38–52%) and is available for up to 7 years. The employer must apply before the employee starts work.

What are the eligibility requirements for the researcher tax scheme?

The employee must meet a minimum salary threshold (~858,000 DKK/year or ~71,500 DKK/month in 2026) and qualify as a researcher (PhD-level or equivalent research work) or key employee (specialist knowledge with decision-making power). The scheme is not available if the individual was a Danish resident for 10+ years before the employment start.

How do I apply for the researcher tax scheme?

The employer must initiate the application through SKAT before the employment start date. Required documentation includes: job description, qualification certificates (PhD, CV, publication list), employment contract with salary details, and proof of salary level meeting the threshold. SKAT typically processes applications within 30 days. The scheme cannot be applied retroactively.

Can I claim deductions while on the researcher tax scheme?

Generally no — personal deductions (interest expenses, commuting, trade union fees) cannot be claimed during the scheme period. However, certain deductions can be carried forward for use after the 7-year scheme ends. Investment income (dividends, capital gains, interest) is taxed under standard rules and is not covered by the 27% rate.

What happens after the 7-year scheme ends?

After the 7-year period, you transition to the standard Danish progressive tax system (38–52% depending on income). You become eligible for personal deductions that were blocked during the scheme. Some employers offer salary adjustments to mitigate the tax increase. You cannot re-enter the scheme, even after a period of non-residence.
