Denmark's researcher tax scheme: a flat 27% in place of the ladder, from DKK 65,400 a month

By Skyler Bissell · September 10, 2026 · 10 min read

DKK 74,165 a year is what Denmark's researcher tax scheme is worth on a DKK 1,000,000 salary in Copenhagen. Under the scheme the person keeps DKK 671,600 of it. On the ordinary ladder the same person keeps DKK 597,435. The effective rate moves from 40.3% to 32.8%, and the gap, about $11,498, comes from one substitution: five progressive taxes are replaced by a single flat 27%, and two deductions are given up in exchange.

Denmark's researcher tax scheme (forskerskatteordningen, sections 48 E and 48 F of the Danish withholding tax act, kildeskatteloven) taxes the salary of a newly recruited employee or researcher at a flat 27% after the 8% labour-market contribution, 32.84% of gross all in, with no deductions of any kind, for up to 84 months that may be split into several periods. It is open to anyone paid at least DKK 65,400 a month on average across the calendar year (2026) who has not been liable to Danish tax at any point in the previous ten years, and to approved researchers without the salary test.

TL;DR

What the flat 27% replaces, and what it gives up

Danish income tax is a stack rather than a single ladder. The labour-market contribution, AM-bidrag, takes 8% of gross first and has no allowance. Everything after it is measured on the remaining 92%, which the statute calls personal income. From that base the state's bundskat of 12.0% and Copenhagen's kommuneskat of 23.4% run on income above the personal allowance of DKK 54,100, with two employment deductions (an earned-income deduction capped at DKK 63,300 and a job deduction capped at DKK 3,100) trimming the municipal base. Above DKK 641,200 of personal income the 2026 reform adds mellemskat at 7.5%, above DKK 777,900 topskat at a further 7.5%, and above DKK 2,592,700 a top-topskat of 5%.

The researcher scheme keeps the first line and deletes the rest. AM-bidrag is still charged on gross, and the 27% is then charged on the 92% that remains, which is how the statutory all-in rate comes to 0.08 plus 0.27 times 0.92, or 32.84%. Bundskat, kommuneskat and all three upper tiers disappear. So do the personal allowance and both employment deductions: Skattestyrelsen's guidance says a person covered by the scheme "is not entitled to any deductions" from that income. The trade is a flat rate with no tax-free floor against a progressive stack with two of them.

Rates and thresholds as our engine carries them for 2026, personal income measured after AM-bidrag, church tax omitted. The upper tiers are charged on personal income, so the deductions never reach them on either path.

The labour-market contribution is the proof that the scheme is a substitution rather than a discount on everything. On DKK 1,000,000 in Copenhagen the AM-bidrag is DKK 80,000 on the ordinary path and DKK 80,000 under the scheme. The whole of the DKK 74,165, 7.4% of the salary, comes from the taxes stacked above it: DKK 402,565 of tax and contributions on the ordinary path becomes DKK 328,400 under the scheme, and nothing else on the payslip moves.

Where the value goes as the salary falls

Because the scheme replaces the top of the ladder with a flat rate, it is worth most to the people who would otherwise sit highest on the ladder. At DKK 3,000,000 in Copenhagen, above the top-topskat line, the ordinary effective rate is 49.9% and the scheme is worth DKK 513,090 a year, 17.1% of the salary. At DKK 2,000,000 the ordinary rate is 47.3%, the scheme keeps DKK 1,343,200 of the salary and is worth DKK 289,445, about $44,875, or 14.5% of gross. At DKK 1,500,000 the ordinary rate is 45.0%, the scheme keeps DKK 1,007,400, and the value is DKK 181,805, 12.1% of gross.

Keep going down and the value thins. A USD 150,000 salary, which converts to DKK 967,500, carries an ordinary rate of 39.8%, and the scheme is worth $10,414 a year on it, the smallest computed value of any regime in our set at that salary, as every regime's duration, ranked and priced shows. At the floor itself, DKK 786,000, the ordinary rate is down to 36.9%, the scheme's is 32.8%, and the gap is DKK 32,204 a year, about $4,993, or 4.1% of gross. A person on the floor keeps DKK 527,878 under the scheme and DKK 495,674 without it, paying DKK 258,122 against DKK 290,326.

Below the floor the scheme is closed and our engine refuses to apply it, so what follows is the ordinary rate on its own. At DKK 600,000 a Copenhagen salary pays 34.8% all in. At DKK 500,000 it pays 33.6%. At DKK 400,000 it pays 32.6%, which is already under the scheme's 32.84%. The two lines cross at roughly half the floor. That is the shape to hold in mind: a flat rate with no allowance is a bad deal on a modest salary, a wash somewhere around DKK 400,000, and a growing discount above it, and the statute's salary test sits far enough up the ladder that everyone who can use the scheme gains from it.

The test is still a step. At DKK 785,999 the engine refuses the scheme and at DKK 786,000 it grants it, and the single krone carries DKK 32,204 of take-home across the line. Sweden's expert tax has the same shape at SEK 88,801 a month, and the line that decides Swedish expert tax is worked from both sides there. Belgium's regime has one too, at €70,000, and its step is larger because the rate it removes is steeper: Belgium's inbound regime, explained.

The value also moves with the municipality, because kommuneskat is one of the taxes the flat rate replaces. Aarhus levies 24.5% against Copenhagen's 23.4%, so on DKK 1,000,000 the ordinary rate there is 41.2% and the scheme is worth DKK 83,199, against Copenhagen's DKK 74,165. The flat rate is the same in both cities; the ladder underneath it is a little steeper in Aarhus, so the gap it closes is a little wider.

The floor: DKK 65,400 a month, averaged over the calendar year

The salary condition is written monthly. For 2026 the scheme requires pay of at least DKK 65,400 a month, and Skattestyrelsen tests it as an average rather than payslip by payslip: the condition holds as long as "your average monthly salary over the calendar year still meets the minimum salary requirement". The figure is measured before the labour-market contribution comes off, and the statute adds the ATP pension contribution on top of it. Our engine tests an annual figure of DKK 786,000, which is twelve months of DKK 65,400 plus the employee's ATP share of DKK 99 a month, rounded up to the nearest thousand. The monthly figure is indexed each year and was lowered for 2026 from the DKK 78,000 that applied before, so a guide quoting the older line is quoting a harder door than the one that exists now.

Averaging cuts both ways. A bonus paid in December can lift a year that ran under the line for eleven months, and unpaid months can sink a year that looked safe in January. The calendar year is what the tax agency checks, so an offer letter that lands a few thousand kroner under the line each month is an offer letter to renegotiate before signing rather than after. The directory of expat regimes ranked by the door puts this floor beside the Dutch, Belgian and Swedish ones; in local terms it is the second-highest of the four, and the first krone inside it is worth the least.

Researchers reach the scheme by a second door with no salary test. Skattestyrelsen requires "a research-qualifying degree at minimum PhD level", and the researcher must be accepted as such under the rules that apply to the position. Our engine tests the salary door only, so a postdoctoral researcher on DKK 600,000 who qualifies by approval will see no relief in our Copenhagen figures, and their real position is better than we show.

84 months, split as you like, and ten years of nothing before

The term is 84 months of employment under the scheme, and Skattestyrelsen says the seven years "may be split into several periods". Someone who uses 36 months, leaves Denmark, and comes back later can use the remaining 48. Our data carries 7 years, and the engine never spreads the value across a stay, because it prices one steady-state year. Held flat at DKK 1,000,000, the full term is worth about DKK 519,000 of tax, and at the floor about DKK 225,000.

The look-back is the longest of any European regime. The person must not have been liable to Danish tax, fully or in a limited way, at any point in the ten years before the employment starts. Limited liability counts, so a foreign resident who once sat on a Danish board, drew a Danish rental income or worked a Danish assignment inside the window is out, even though they never lived in the country. The Netherlands and Belgium look back 60 months, Spain and Ireland five tax years; Denmark's ten is the door that turns away anyone who has been near Denmark before, and there is no discretion in it.

Two more clocks run beside it. The employment and the Danish tax liability must begin together: the scheme is for people whose liability starts with the job, so someone who moves to Copenhagen, becomes tax-resident, and finds a job three months later has missed it. And the statute bars anyone who, in the five years before starting, had a part in the management or control of the employer, which closes the scheme to a founder who moves to Denmark to run the Danish subsidiary of a company they own.

The conditions our engine does not test

Our engine tests one thing: whether the salary clears DKK 786,000 a year. Everything else in the scheme sits outside the calculation, and five of those conditions do most of the work in practice.

The scheme also ends. When the 84 months are used up the ordinary ladder applies, the allowance and deductions return, and on a DKK 1,000,000 salary the tax bill rises by the DKK 74,165 the scheme had been worth. Where that cliff sits beside the Dutch, Spanish and Belgian ones, and which clocks can be paused, is in how long every expat tax regime lasts.

What our figures model, and how to run your own

The Danish figures on this page are a single filer with no children on the 2026 rates, Copenhagen's kommuneskat unless Aarhus is named, no church tax, the 8% AM-bidrag on gross, and on the ordinary path the personal allowance and both employment deductions. Under the scheme the engine charges 27% of the post-contribution base and deducts nothing, which is the statute's own arithmetic. Spouses are taxed individually in Denmark and the scheme is granted per person, so a two-earner household is two of these calculations, and a partner who does not clear the floor is taxed on the ordinary ladder beside a partner who does.

Denmark sits in the group of countries whose inbound relief our engine can price at all; the reasoning behind the split between the seven regimes we compute and the six we carry as notes is in expat tax breaks, decoded. What the scheme leaves a person against Amsterdam, Madrid and Stockholm on one salary is in every expat tax regime ranked by take-home, where Copenhagen finishes in the middle of the table, because its ordinary rate on that salary is moderate to begin with once the employment deductions are counted. Where that ordinary layer sits country by country, with no regime applied, is in take-home pay by country.

If a Copenhagen offer is in front of you, put your own salary and household into the New York to Copenhagen comparison, then switch the regime toggle on and off. The difference between the two runs is what the scheme is worth to you, at your salary, in your municipality, on this year's floor. If the toggle changes nothing, you are under the line, and the page will say so.

FAQ

Is the Danish researcher tax scheme 27% or 32.84%?

Both, on different bases. The statute sets a flat 27% on salary after the 8% labour-market contribution has come off, and since that contribution is charged on the whole gross, the two together take 32.84% of gross: 0.08 plus 0.27 times 0.92. Skattestyrelsen quotes the 32.84% figure itself. Every rate on this page is measured on gross, so the scheme's rate is written as 32.84% throughout and set against ordinary effective rates measured the same way.

Do you have to be a researcher to use Denmark's researcher scheme?

No. The scheme has two doors. Researchers enter through an approval: a research-qualifying degree at PhD level or above, and acceptance under the rules that apply to the position, with no salary test. Everyone else enters through the salary test, DKK 65,400 a month on average across the calendar year in 2026 plus the ATP contribution, whatever their field. Most people on the scheme came through the salary door, which is why it is also called the key-employee scheme. Our engine tests the salary door only.

What happens when the 84 months on the Danish researcher scheme run out?

The ordinary ladder applies from then on, with the personal allowance and the employment deductions back in place. On a DKK 1,000,000 Copenhagen salary that is a rise in tax and contributions from DKK 328,400 to DKK 402,565, the DKK 74,165 the scheme was worth, arriving in a single payslip. The months may be used in several periods, so someone who leaves Denmark with time unused can use the remainder on a later stay.

Can you claim deductions under the Danish researcher scheme?

No. Skattestyrelsen's guidance is that a person covered by the scheme is not entitled to any deductions from the income it covers: no personal allowance, no employment deduction, no interest or commuting deduction against the scheme salary. That is why the scheme is worth only 4.1% of gross at the salary floor even though 32.84% sits far below Denmark's top marginal rates. At that salary the ordinary path's allowance and deductions do real work, and the scheme gives them up.
