Quick Summary
Denmark taxes RSUs as salary on the day they vest, at the shares’ market value that day, and a sale years later is a separate, smaller tax event.
Relevant to anyone who is a Danish tax resident and receives stock from a US parent company; US citizens and green card holders also owe US tax on the same vest.
AM-bidrag of 8 % comes off first and bracket tax applies to what’s left, while a later gain is share income at 27 % up to DKK 79,400 and 42 % above it.
The IRS taxes the vest as ordinary income on the same date, and the Danish and US bills don’t always offset each other automatically.

Denmark taxes your RSUs as salary on the day they vest, at whatever the shares are worth that day. Many people expect the bill to arrive when they sell, the way it does for an ordinary stock gain, and get caught out by tax on shares they’re still holding.
If you’re a US citizen or green card holder working for the Danish arm of a US company, and part of your pay arrives as stock in the American parent, the same vest also lands on your US return. This article covers how the two systems interact, where they usually cancel each other out, and where they don’t.
It covers restricted stock units and US federal tax only. Stock options, warrants and US state tax follow different rules.
What happens on the day your stock vests
Danish tax law doesn’t care that your RSUs came from a US company. Once the conditions on the award are met (usually just “still employed on this date”), the market value of the shares, less anything you paid for them, counts as personal income, according to Skattestyrelsen’s (the Danish Tax Agency’s) legal guidance on employee shares taxed as salary (in Danish).
Personal income (personlig indkomst) is taxed like your salary. AM-bidrag, the labor market contribution of 8 %, comes off first, and bracket tax then applies to what’s left. Stacked on a high salary, the combined marginal rate on a vest tops out around 56% before church tax.
Your employer is expected to withhold A-skat (income tax withheld at source) and AM-bidrag on the vest and report it, the same as on a cash bonus. Most equity platforms cover the bill by selling enough of the new shares automatically, a mechanic called sell-to-cover, so you end up with fewer net shares than you were granted.
If no one withholds, because the plan runs outside Danish payroll, the value is still your income. The tax then surfaces as restskat (outstanding tax) on your årsopgørelse (annual tax assessment).
| Event | Denmark | United States |
|---|---|---|
| Grant | No tax while the vesting conditions are open | No tax |
| Vesting | Taxed as personal income at market value; AM-bidrag and A-skat withheld | Taxed as ordinary income at market value when the shares are delivered, usually the vest date |
| Later sale | Gain or loss since vesting taxed as share income (aktieindkomst) | Gain or loss since vesting taxed as a capital gain, short or long term depending on holding period |
Tip
For a typical RSU, vesting is a salary event in both countries, on the same date, for the same value.
The later sale is a separate and usually much smaller tax question in each.
What a vest does to your tax bracket
The bracket thresholds apply to personal income after AM-bidrag has come off, according to Skattestyrelsen’s page on the bracket taxes. That detail decides which bracket a vest lands in.
Case Study
Anna (a fictional character for the sake of this example) is a Danish tax resident in the Copenhagen office of a US-listed software company. Her salary is DKK 620,000 a year.
On 15 March, 220 of her RSUs vest at a closing price equivalent to DKK 850, a total of DKK 187,000. AM-bidrag takes 8 % of that, DKK 14,960, leaving DKK 172,040.
Her salary alone puts personal income after AM-bidrag at about DKK 570,400. The vest lifts it to about DKK 742,400: over the mellemskat threshold of DKK 641,200, but about DKK 35,500 short of the topskat threshold of DKK 777,900.
About DKK 70,800 of the vest is taxed at the bundskat rate of 12.01% plus the national average municipal rate of 25.05%, roughly 37% together. The other DKK 101,200 also carries mellemskat at 7.50%, roughly 44.6% in all (before church tax, and assuming salary has already used up her personal allowance).
With AM-bidrag, the vest costs her about DKK 86,300 in tax, 46% of its value. Her employer’s platform sells just over 100 shares to cover it, and she keeps just under 120.
Three years later she sells those 118 shares at DKK 1,050 each. Her Danish cost basis is the DKK 850 she already paid salary tax on, so the gain is DKK 200 per share, about DKK 23,600 in total. Assuming no other share income that year, it’s taxed as aktieindkomst at 27 %, about DKK 6,400, because it sits well under the DKK 79,400 threshold.
A vest doesn’t have to be Anna-sized to matter. At senior levels, one vest can push the year’s personal income past DKK 2,592,700, where the additional top bracket adds 5 % on the excess.
Tip
A large vest can leave a year’s withholding out of step with what you owe, especially if your forskudsopgørelse (preliminary income assessment) hasn’t been updated. Update it before a known large vest.
Unpaid tax becomes restskat. It accrues interest at an annual rate of 3.70%, charged daily from the 1 January after the income year until you pay or until 1 July, when a flat surcharge replaces it, according to Skattestyrelsen’s page on paying outstanding tax. On DKK 20,000 of restskat that’s about DKK 60 a month.
That rate is fixed by the income year the årsopgørelse covers, whenever you pay, and a new one is set each December. A voluntary payment (frivillig indbetaling) made before year end avoids the interest.
Why the employee-share scheme rarely applies to a US grant
Danish law has a friendlier route for employee shares (medarbejderaktier). If an award qualifies, its value isn’t taxed as salary at all: it’s taxed as share income when you sell, at 27 % or 42 %, with no AM-bidrag and no tax bill before you’ve sold anything.
The catch is paperwork. The law requires a written agreement between you and the employer saying the scheme applies, with the award clearly identified by type, company and terms, according to the Tax Assessment Act (ligningsloven) (in Danish). A global equity plan document that never mentions Danish law doesn’t do that on its own.
There’s also a value cap. The award can’t be worth more than 10 % of your annual salary when you sign the agreement, or 20 % if it’s open on equal terms to at least 80 % of the company’s employees, according to Skattestyrelsen’s guidance on the 10 percent limit (in Danish). On a DKK 620,000 salary, 10% is DKK 62,000, a third of Anna’s DKK 187,000 vest, and a single year’s vest at a US tech employer often blows past the cap.
From 1 July 2026, a wider version applies to new, smaller, unlisted companies: up to 150 employees, up to DKK 200 million in turnover or balance sheet total, and operating for under 10 years. For those companies the percentage cap is gone, replaced by a minimum taxable annual salary of DKK 265,300 when you sign, according to the Ministry of Taxation and Growth’s announcement (in Danish). It covers only agreements signed after that date, and a listed US parent can’t use it.
Put together, a standard RSU grant from a large listed US employer almost never qualifies as of 2026. The salary rules are the default, and they apply unless your employer can point to a signed agreement covering this specific award.
Tip
Ask HR to confirm in writing whether a signed agreement covers this specific award under the employee-share scheme in the Tax Assessment Act, which employers call section 7P.
Selling the shares later
Once your RSUs vest, the shares behave like any other stock you own. Denmark taxes a later sale under the realization principle (realisationsprincippet): a gain or loss counts only in the year you sell.
The wrinkle is how Denmark measures that gain once you’ve built up shares from several vests. The average-cost method (gennemsnitsmetoden) pools all shares in the same company, including shares you received through an employee share scheme, and measures a partial sale against that single average, according to Skattestyrelsen’s page on buying and selling shares. You can’t pick which vest you’re selling.
| Item | Denmark | United States |
|---|---|---|
| Which shares count as sold | One pooled average cost per company | Each vest is its own lot with its own cost basis |
| Tax treatment | Share income: 27 % up to DKK 79,400, 42 % above | Capital gain: ordinary rates within a year, lower long-term rates after |
| Starting point | Vest-date value, already taxed as salary | Vest-date value, already taxed as ordinary income |
One reporting step is easy to miss because the paperwork isn’t Danish. Danish banks report share purchases to Skattestyrelsen, but a US brokerage doesn’t, so you report the purchase yourself in TastSelv by 1 July of the year after purchase or lose the right to deduct a loss on those shares, according to the same Skattestyrelsen page. The page is written for purchases, so reporting a vest on the same deadline is the cautious reading.
If you sell US-listed shares and bring the dollars to Denmark, the exchange rate is a real cost. A transfer service such as Wise (partnerlink/reklamelink) shows its fee and exchange rate before you send, which makes it easy to compare against your bank’s quote on the same day.
The US side: ordinary income now, capital gain later
The IRS treats shares delivered in settlement of an RSU as wages, taxed as ordinary income at their fair market value when they’re delivered, usually the vest date, according to an IRS Chief Counsel memo on RSUs. The memo shows the agency’s position but can’t be cited as precedent. The income lands on your US return for that year, wherever you live.
Working for a Danish entity changes who withholds. Your Danish employer generally doesn’t withhold US income tax, so the US bill is yours to report and pay on your return, the same as for your Danish wages. A US parent that delivers the shares may still withhold: on the memo’s facts, the parent stays responsible for withholding on RSU income paid to a US citizen working for a foreign subsidiary.
Once you’ve paid ordinary income tax on the vest-date value, that value becomes your US cost basis, and your holding period starts the day after the vest. Sell within a year and any gain is short-term, taxed at ordinary rates; hold longer and it qualifies for lower long-term rates, according to the IRS’s page on capital gains and losses.
Foreign earned income exclusion or foreign tax credit
Two US tools can keep a vest from being taxed twice. You can’t take a foreign tax credit for tax on income you exclude, according to the IRS page on choosing the exclusion, so the choice shapes the whole return. The exclusion’s annual limit is set out on the IRS page on figuring the exclusion.
| Foreign earned income exclusion | Foreign tax credit | |
|---|---|---|
| How it works | Excludes up to USD 132,900 of foreign earned income from US tax | Credits the Danish income tax you paid against the US tax on the same income, up to a limit |
| Fit for a large vest | The limit is shared with your salary, and anything above it is fully taxable in the US | Usually the better fit, because for most salaries Danish tax on a vest exceeds the US federal tax on it |
| Where it gets complicated | Covers only foreign-source earned income, so a US-source slice stays taxable | The limit depends on correctly sourcing and categorizing the income |
Where double taxation can bite: a vesting period split across two countries
For someone who lived and worked in Denmark for the whole stretch between grant and vest, the two bills usually reconcile cleanly: Denmark taxes the vest as salary, the US taxes it as ordinary income, and the foreign tax credit offsets one against the other. That picture breaks if any of the vesting period was spent working somewhere else, most often in the US before a move or on a return assignment.
The IRS sources multi-year pay, including equity awards, by time: it compares the days you worked in the US with the days you worked elsewhere between grant and vest, according to the IRS’s practice unit on multi-year compensation. The foreign tax credit only offsets US tax on income the US treats as foreign-source, so the US-source share of the vest gets no credit from it.
Case Study
Mark is granted an award while working in Austin. He moves to Copenhagen 12 months later, and the award vests 36 months after the grant.
On the IRS’s time basis, about one third of the vest (12 of 36 months) is US-source and about two thirds is foreign-source, so the foreign tax credit can only offset US tax on the two thirds.
How Denmark treats an award that vests after a move into Denmark is a separate set of rules, and it doesn’t have to produce the same split. Whether the US-source third ends up fully relieved depends on the credit rules in Danish law and the US-Denmark tax treaty, which this article doesn’t try to settle.
A vesting period that crosses a move is the kind of multi-jurisdiction calculation a generalist accountant on either side of the Atlantic can get wrong, and correcting it after filing costs more than getting it right first. This is where a cross-border tax specialist who handles US-Denmark cases earns the fee: on the Danish side, a state-authorized public accountant (statsautoriseret revisor) listed in the Danish Business Authority’s register of approved auditors (in Danish), and on the US side, a CPA or enrolled agent from the IRS directory of tax preparers with credentials.
Tip
If your grant letter shows a grant date from before you moved to Denmark, or any part of the vesting period was spent working in the US, pull your workday count for each country before anyone touches a foreign tax credit form. Ask HR or your equity platform for the grant and vest dates if you don’t have them.
Where the sale proceeds go matters for Americans
Vested RSU shares are ordinary company stock, and a US parent is a domestic corporation. That keeps them outside the PFIC (passive foreign investment company) rules, the US regime that taxes many non-US funds at punitive rates. The IRS instructions for Form 8621 define a PFIC as a foreign corporation that meets an income or asset test.
That changes when the proceeds are reinvested. Most Danish-domiciled funds and ETFs count as PFICs for a US taxpayer, including those held inside an aktiesparekonto (ASK), Denmark’s tax-advantaged stock account. The PFIC regime brings punitive tax treatment and extra annual reporting on money that started as ordinary, already-taxed salary.
Which products the proceeds go into is worth settling with a cross-border adviser before the sale.
Bottom Line
For an employee who stayed in Denmark from grant to vest, an RSU is a salary event with a predictable bill: Denmark taxes it at vest, the US taxes it at the same moment, and the foreign tax credit exists to reconcile the overlap. The risk sits at the edges: a vesting period that crosses a move, a sale that Denmark pools and the US measures lot by lot, or proceeds reinvested in a Danish fund wrapper built for a different tax profile. Those are the moments to call a cross-border specialist, and the useful time to call is before the vest or the sale.
