Denmark Start-Up Visa

Local tax regime and what it means for you

Denmark uses a worldwide tax regime for residents: once you are tax resident, Denmark taxes your global income, not just Danish-source income. That includes remote salary from a foreign employer, self-employment profits from your Danish startup, ETF dividends from a US or other foreign brokerage, pension distributions, and rental income from property abroad. Rates are high by global standards, with combined municipal and state income tax often in the 37–52% range for middle to higher incomes, plus labour-market contributions. There is no territorial or remittance-based carve‑out that would leave foreign passive income untaxed once you are resident.

For capital gains on foreign investments such as index funds or ETFs held in a US brokerage, the default treatment is taxation in Denmark for residents. Capital gains on portfolio investments fall into Denmark’s general rules for share income and capital gains and are taxed; they are not exempt under any territorial rule and are not limited to amounts remitted into Denmark. This is the key point for FIRE readers: if you sell ETFs or mutual funds while Danish tax resident, gains are subject to Danish tax at the applicable share‑income or capital‑gains rates, not at 0%.

Tax residency in Denmark is generally triggered either by having a home available to you in Denmark or by physical presence for at least 183 days in a 12‑month period, but the exact statutory tests are not specified in the provided visa facts. In practice, most Start-Up Denmark holders who move their life to Denmark for 24 months will be treated as tax resident from arrival, once they register their address and obtain a civil registration number (CPR). There is no separate, opt‑in tax residency status for this visa type; your factual circumstances drive the result.

New residents must obtain a CPR number and register with the Danish tax authority (Skattestyrelsen). Once registered, you receive a tax card, and Danish clients or employers withhold tax based on that card. Residents file an annual tax return (årsopgørelse) covering worldwide income; deadlines are generally in March–May for the prior calendar year, with much information pre‑filled but foreign income and accounts needing manual entry. Failure to report foreign income or accounts can trigger back taxes, interest, and penalties.

The US–Denmark income tax treaty status is marked as unknown in the visa facts, so you cannot assume treaty relief on pensions, dividends, or self‑employment income. Denmark does have tax treaties with many countries, including the US, but specific treatment of Social Security, dividends, and capital gains depends on treaty articles and domestic implementation. With an “unknown” status in this dataset, you need to check the current US–Denmark treaty text or obtain professional advice instead of relying on generalized assumptions.

For US Citizens and Green Card Holders

As a US person, you remain taxable by the IRS on worldwide income even if you become fully tax resident in Denmark under the Start-Up Denmark scheme. Three main tools interact with Danish taxation: the Foreign Earned Income Exclusion (FEIE), Foreign Tax Credit (FTC), and the foreign reporting regimes (FBAR/FATCA).

FEIE (Form 2555) can shelter up to 126,500 USD of earned income in 2024 (salary or self-employment, not dividends or capital gains). If your main income is self-employment profit from your Danish startup, FEIE can exclude part of that from US income tax if you pass either the Physical Presence Test (330 days abroad in any 12-month period) or the Bona Fide Residence Test. With a 24‑month Danish residence permit and likely 183+ days per year in Denmark, most founders will rely on the Bona Fide Residence Test after the first full calendar year, while using the Physical Presence Test during the initial partial year.

The Foreign Tax Credit (Form 1116) becomes crucial because Denmark taxes worldwide income at relatively high rates. For self‑employment income, salary, rental income, and portfolio dividends/gains, the Danish effective tax rate will often exceed US rates for many income bands. In those cases, you generally claim FTC on the same income rather than FEIE, or in combination, to avoid double taxation. If a particular income stream ends up at a 0% Danish rate (uncommon in Denmark but possible for some limited situations), FTC gives you no offset against US tax for that stream.

Foreign account reporting is unavoidable if you bank in Denmark. If your aggregate foreign financial accounts (Danish bank accounts, investment accounts, certain pensions) exceed 10,000 USD at any point in the year, you must file FBAR (FinCEN Form 114) electronically. Separately, FATCA Form 8938 may be required once foreign assets exceed thresholds starting at 50,000 USD for many filers. Non‑willful FBAR penalties start at 10,000 USD per year, so “forgetting” the Danish account you use to run your startup is a costly error.

For this visa, the optimal setup often involves: using FEIE and/or FTC strategically for your startup profits, understanding how Denmark taxes your ETF sales and US rental income, and staying ahead on FBAR/FATCA compliance. The smart move is to engage two advisors in year one: a US CPA specializing in expat taxation who understands FEIE/FTC/FBAR/FATCA interactions, and a Danish tax advisor who can handle registration, your årsopgørelse, and treaty application. The 1,500–3,000 USD you spend on that initial guidance is usually offset by correct elections, reduced double taxation, and avoided penalties.
