Learn › Investment tax Denmark

In short: In Denmark (2026), investment returns fall into two boxes. Share income (dividends and gains on individual shares and equity funds on SKAT's positive list) is taxed at 27% up to DKK 79,400, then 42% above that (the 27% band doubles to DKK 158,800 for married couples). Capital income (interest, bonds, and any fund/ETF not on the positive list) is folded into ordinary income at roughly 37%-42%, capped at 42% marginal. Most foreign ETFs are taxed yearly under the lager (mark-to-market) principle on the change in value whether or not you sell. There's no tax-free allowance. An Aktiesparekonto offers a flat 17% rate up to a DKK 174,200 deposit cap for 2026.

Capital Gains & Investment Taxation in Denmark (2026)

Kontoo editorial team · Updated 06/25/2026 · 7 min read

Denmark sorts your investment returns into two boxes with very different rules: share income (aktieindkomst) and capital income (kapitalindkomst). Which box your fund or ETF lands in decides both the rate you pay and whether you're taxed only when you sell or every year on paper gains. There's no general tax-free allowance, and the single most important thing for fund investors is a list maintained by the tax authority. This is general education, not tax advice, and rules can change.

Find out which box each holding sits in. Individual shares and Danish equity funds usually count as share income; bonds, interest and off-list funds count as capital income.
Check SKAT's positive list every year. An equity ETF on the 2026 list is taxed as share income; the same ETF off the list is taxed as capital income, even if it holds the same stocks.
Know whether you're taxed on sale or yearly. Most foreign ETFs are taxed under the lager (mark-to-market) principle, so paper gains are taxable each year even without a sale.
Consider an Aktiesparekonto (ASK) for a flat 17% rate on eligible shares and funds, up to the 2026 deposit cap of DKK 174,200.

What matters

Denmark's defining choice is the split between two boxes. Share income (aktieindkomst) is the favourable box. It covers dividends and realised gains on individual shares (listed and unlisted), Danish equity-based funds, and foreign equity ETFs that appear on SKAT's positive list. The rate is 27% on the first DKK 79,400 of share income (up from DKK 67,500 in 2025) and 42% above that. For a married couple living together at year-end, the 27% band doubles to DKK 158,800, and the unused part transfers between spouses. Individual shares are taxed on realisation, so tax falls due only on sale or dividend. Losses on listed shares are ring-fenced, deductible only against other share income and carried forward indefinitely, but a trap applies: the loss is only deductible if SKAT received the purchase information by 1 July of the year after you bought. Capital income (kapitalindkomst) is the less favourable box. It captures interest from bank deposits and bonds, bond gains, certain foreign-currency gains, and any fund or ETF not on the positive list, including economically equity-based ones. Net capital income is folded into ordinary income and taxed progressively, with an effective marginal rate of roughly 37%-42% depending on municipality, church tax and total income, capped at 42% in 2026. Positive net capital income above about DKK 55,000 (DKK 110,000 for couples) is included in the middle-bracket (mellemskat) calculation, though the overall capital-income marginal rate is still capped at 42%. Negative net capital income, such as mortgage interest, is only deductible at a reduced value of roughly 25%-33%. Dividends: Danish-source dividends carry 27% withholding at source, credited against your final share-income tax. Interest is capital income, with no separate flat rate or savings allowance. Denmark has no general tax-free allowance for investment income; the one small relief is a DKK 2,000 threshold for bond and foreign-currency gains: gains and losses on bonds and foreign-currency items are tax-free if the combined annual net is DKK 2,000 or less, but once it exceeds DKK 2,000 the full amount is taxable or deductible, not just the part above the threshold.

ExampleImagine you're single with DKK 100,000 of share income in 2026 from listed shares and on-list funds. The first DKK 79,400 is taxed at 27% = DKK 21,438. The remaining DKK 20,600 is taxed at 42% = DKK 8,652. Total tax: DKK 30,090, an effective rate of about 30.1%. Now suppose the same DKK 100,000 came from an ETF that is off the positive list. It would be capital income, taxed at roughly 37%-42%, so DKK 37,000-42,000. The same economic return costs you several thousand kroner more purely because of the fund's list status.

Before buying any ETF, search its ISIN against SKAT's positive list for the current year. That one check decides whether your returns are taxed at the favourable 27%/42% share-income rate or the higher ~37%-42% capital-income rate. To picture how the lager tax nibbles at long-term compounding, try a compound-interest calculator and re-run it with the rate applied annually.

In depth

The lager (mark-to-market) principle

Most foreign ETFs and accumulating or distributing investment funds are treated as investment companies (investeringsselskaber) and taxed under the lager principle. Each year you're taxed on the change in value, realised and unrealised, plus any distributions, whether or not you sold. This is very different from the realisation principle that applies to individual shares, where tax waits for a sale. Practically, lager means you can owe tax in a year with strong paper gains even though no cash arrived, so it's worth keeping some liquidity aside. It also dampens the long-run benefit of tax deferral that buy-and-hold investors enjoy in realisation-based systems.

The Aktiesparekonto (ASK)

The share savings account applies a flat 17% annual tax on returns, also under the lager principle, which is well below both the share-income and capital-income rates. The 2026 deposit cap is DKK 174,200, measured at market value on 31 December 2025 and up from DKK 166,200 in 2025. You can top up the gap between the cap and your year-end market value, re-deposit within the year after withdrawals, and always re-deposit an amount equal to tax paid on the prior year's return. Only assets on the ASK-eligible list, broadly the positive-list ETFs and shares, may be held, and losses inside the account can be offset against future ASK gains.

Foreign withholding tax and credits

Foreign dividends and interest are fully taxable in Denmark in the relevant box. Denmark grants a foreign tax credit, typically capped at the treaty rate, for example 15% on portfolio dividends, against your Danish tax. If the source country withheld more than the treaty rate, the excess isn't credited in Denmark and must be reclaimed from that country directly, which can be slow. Unlike the UK, Denmark has no reporting-fund regime; its equivalent gatekeeper is the positive-list and investment-company classification. The exact thresholds and the kapitalindkomst effective rate depend on your municipality and total income, so confirm figures against SKAT's final 2026 rate table.

Checklist

You confirmed whether each holding is share income or capital income
You checked the fund against SKAT's 2026 positive list this year
You know whether each holding is taxed on sale or yearly under lager
You considered an Aktiesparekonto for its flat 17% rate and DKK 174,200 cap

Common myths

Myth: Accumulating ETFs let me defer Danish tax until I sell.

Reality: Not for most foreign ETFs. They're taxed under the lager principle, so unrealised gains are taxed each year regardless of whether the fund pays out or you sell anything.

Myth: If a fund holds equities, my gains are automatically taxed at the favourable share-income rate.

Reality: Only if the fund is on SKAT's positive list for that year. An equity ETF off the list is taxed as capital income at the higher ~37%-42% rate, despite holding the same stocks.

Frequently asked questions

Are accumulating ETFs more tax-efficient than distributing ones in Denmark?

Usually not. Most foreign ETFs are treated as investment companies and taxed under the lager principle, meaning yearly tax on paper gains whether or not income is distributed. The accumulating-versus-distributing distinction matters far less than whether the fund is on SKAT's positive list (share income) or off it (capital income).

What is the positive list and why does it matter so much?

It's an annual list (updated 15 December 2025 for 2026, now over 5,000 funds) of equity-based funds whose issuers applied to SKAT. A fund on the list is taxed as share income at 27%/42%; an identical fund off the list is taxed as capital income at roughly 37%-42%. Status is checked year by year, so re-verify it each year.

Do I get credit for foreign withholding tax on dividends?

Yes. Foreign dividends are fully taxable in Denmark, but you generally receive a foreign tax credit up to the treaty rate, commonly 15% on portfolio dividends. Anything withheld above the treaty rate isn't credited and must be reclaimed from the source country.
