Denmark has some of the most comprehensive — and strict — crypto tax rules in Europe. The Danish Tax Agency (Skattestyrelsen) has invested heavily in crypto enforcement.
Core Principles
| Principle | Detail |
|---|---|
| Crypto is an asset | Taxed as capital gains |
| Gains are taxable | No holding period exemption |
| Losses are deductible | Under specific rules |
| No tax-free threshold | Every kroner taxed |
| Inventory method mandated | FIFO (since 2022) |
Capital Gains Tax
| Detail | Rate (2026) |
|---|---|
| Capital gains tax (shares-like) | 27% / 42% |
| Staking rewards | Personal income (up to 52%) |
| Mining | Business income |
Gains Tax Rates
| Gain Amount | Rate |
|---|---|
| Up to DKK 61,000 (2026 est.) | 27% |
| Above DKK 61,000 | 42% |
The FIFO Rule
Denmark mandates FIFO (First In, First Out) for crypto since 2022.
| Purchase | Amount | Price |
|---|---|---|
| Purchase 1 (Jan) | 1 BTC | 200,000 DKK |
| Purchase 2 (Mar) | 1 BTC | 300,000 DKK |
| Purchase 3 (Jun) | 1 BTC | 250,000 DKK |
If you sell 1 BTC, it’s assumed to be Purchase 1 (from January, cost 200,000 DKK).
Taxable Events
| Event | Taxable |
|---|---|
| Sell crypto for DKK | Yes |
| Crypto-to-crypto trade | Yes |
| Buy goods/services with crypto | Yes |
| Gift to non-family | Yes (disposal) |
| Transfer between own wallets | No |
| Gift to spouse | No |
Staking and DeFi
| Activity | Tax Treatment |
|---|---|
| Staking rewards | Personal income (progressive, up to 52%) |
| Airdrops | Taxable as other income |
| DeFi lending | Interest is taxable |
| Liquidity mining | Taxable as income |
| Wrapped tokens | May trigger disposal event |
Loss Deduction
| Loss Type | Deductibility |
|---|---|
| Loss from sale | Can offset crypto gains |
| Loss from scam/theft | 27/42% deductible |
| Loss from worthless token | Deductible if documented |
Losses can only offset gains of the same type (crypto losses vs crypto gains).
The Exchange Reporting Requirement
Since 2024, Danish exchanges must:
- Report all user transactions to Skattestyrelsen
- Include KYC data
- Report across tax years
Foreign exchanges may also be required to report under international agreements.
Mining
| Aspect | Tax Treatment |
|---|---|
| Mining income | Business income (progressive tax) |
| Deductible expenses | Electricity, hardware, rent |
| VAT | May apply on sales of mined coins |
| Registration | May need CVR number (business registration) |
Reporting
| Requirement | Detail |
|---|---|
| Tax return (Selvangivelse) | File by 1 July |
| Manual reporting | Most crypto must be self-reported |
| Foreign accounts | Report if on foreign exchanges |
| Documentation | Keep for 5 years |
Bottom Line
Denmark has strict crypto tax rules with FIFO method, 27/42% capital gains tax, and no tax-free threshold. The tax agency has strong enforcement powers and exchange reporting requirements. Staking is taxed as personal income at higher rates. Keep careful FIFO records and consider professional help — Danish crypto tax is complex and mistakes can be costly.
Keeping on top of Danish crypto tax
The practical burden of Denmark’s rules is record-keeping. Because FIFO is mandated and there is no threshold, you cannot rely on a tax-free allowance to excuse sloppy records — you need the date and cost, in kroner, of every acquisition in order to work out which batch a disposal draws from first. Most crypto is self-reported on the annual return, so the burden of matching every sale, swap, and staking reward sits with you.
A common point of confusion is that different activities are taxed differently. Holding and selling is capital gains at 27%/42%, but staking rewards, mining, and DeFi lending interest are all taxed as income at the progressive rate, which can reach 52%. That means two people can hold the same coin and owe very different tax depending on how they acquired it. Wrapped tokens can also trigger a disposal event, so a simple bridge swap may be taxable in a way a plain transfer between your own wallets is not.
If you trade heavily, consider using tax software that can apply FIFO and split capital gains from income automatically, then reconcile that against the exchange reports the tax authority already holds. Discrepancies are easy to spot from the enforcement side, so it is safer to report an event you think might be taxable than to omit one. For anyone with a substantial portfolio or cross-border holdings, a Danish tax professional is worth the cost — the combination of strict rules, high rates, and exchange reporting makes small errors disproportionately expensive.
