An Introduction to Crypto Taxes in Denmark

13 June 2024

Cryptocurrency has become increasingly popular as an investment and a medium of exchange. As the use of digital currencies grows, so does the interest of tax authorities in ensuring that these assets are correctly reported and taxed. The Danish Tax Agency (Skattestyrelsen) employs various strategies to identify cryptocurrency holdings and enforce tax compliance in Denmark. Understanding how the tax authorities discover crypto holdings and how crypto is taxed in Denmark is crucial for any Danish resident involved in the cryptocurrency market.

How does the Danish Tax Authority know that I have crypto?

The tax authorities in Denmark, known as the Danish Tax Agency (Skattestyrelsen), have several ways to determine if you have cryptocurrency holdings:

  • Exchange Reporting: Many cryptocurrency exchanges must report user transactions to tax authorities. If you use an exchange operating in Denmark or compliant with international regulations, your transaction data might be shared with the Danish Tax Agency.
  • Data Sharing Agreements: Denmark is part of various international data-sharing agreements and tax information exchange initiatives, such as the OECD’s Common Reporting Standard (CRS). These agreements allow for the exchange of financial information, including details about cryptocurrency holdings.
  • Blockchain Analysis: The Danish Tax Agency can track and analyze cryptocurrency transactions using blockchain analysis tools. These tools can help identify patterns and trace transactions back to individuals, even if they use multiple wallets and addresses.
  • Self-Reporting: Danish taxpayers must report their cryptocurrency holdings and transactions on their tax returns. Failure to do so can lead to penalties if discovered
  • Audits and Investigations: The Danish Tax Agency may conduct audits and investigations based on suspicious activity or discrepancies in reported income. If there is evidence suggesting unreported cryptocurrency income, they can delve deeper into financial records.
  • Third-Party Reports: The tax agency may receive information about individuals’ cryptocurrency activities from various third parties, including banks, other financial institutions, and even other taxpayers.

These methods help the Danish Tax Agency identify individuals with cryptocurrency and ensure compliance with tax regulations.

How is crypto taxed in Denmark?

Cryptocurrency taxation is subject to specific rules depending on the nature of the transactions and the activities involved. The Danish tax authority views crypto as a personal asset. In Denmark, personal assets are only taxed if the asset is part of an individual’s business or if the asset is owned for speculative purposes. Crypto is seen as a speculative asset by the Danish Tax Agency. In general, crypto transactions are subject to either capital gains tax or income tax, depending on the type of transactions.

Income tax on crypto assets: If you engage in trading with Bitcoin and altcoins (such as Ethereum or Polkadot), any profits here will be classified as personal income, subject to a tax of up to 52%.  Transactions that fall under this category include:

  • Selling Bitcoin & altcoins for fiat currency like Danish Krone or the USD
  • Trading Bitcoin & altcoins for another cryptocurrency
  • Spending Bitcoin & altcoins on goods and services
  • Mining
  • Airdrops
  • Hard Forks: At the point that you dispose of the asset (by selling, trading or spending it). A zero-cost basis should be used when making this calculation.
  • Getting paid in crypto

Losses: Offsetting losses against profit is only permitted in certain circumstances. You are allowed to offset losses against gains of the same kind of cryptocurrency, if you have not purchased more of that cryptocurrency in between these transactions. For example, if you owned 3 ETH and and sold some of this during the same financial year which generated both gains and losses, you can offset your ETH loss against any ETH gain. From here, a net calculation can be made to see by how much you can offset the loss against the gain. It is important to note however, this this is only possible if you had not purchased any additional ETH between transactions.

If more ETH had been boughtduring this time, you will need to calculate each transaction indivdually using the FIFO cost basis method, rather than making a net calculation.

Crypto tax breaks and transactions that are not subject to tax in Denmark

In Denmark, most cryptocurrency transactions have tax implications, but there are a few scenarios where transactions might not immediately trigger tax consequences. Here are some instances where cryptocurrency transactions may not have tax implications:

Holding Cryptocurrency: Simply holding or storing cryptocurrency without selling, exchanging, or using it is not taxable. There are no taxes on the mere possession of cryptocurrency.

Transferring Between Own Wallets: Moving cryptocurrency between your wallets does not create a taxable event, as it is not considered a sale or exchange. This includes transferring from a hot wallet to a cold wallet or between different accounts on the same exchange. It is essential to keep track of crypto transactions since the Danish tax authority has not yet clearly defined the treatment of transfer fees.

Charitable Donations: Donating cryptocurrency to registered charities are tax deductible. However, there is a maximum deduction that usually applies to this rule. In 2022, it was 17 200 DKK.

Gifting crypto: The Skattestyrelsen stated that there is no tax owed on gifting crypto if it falls under the speculative category and is of low value. In 2022, gifts were tax-free up to an amount of 69500 DKK, but only applied if the recipient is your child, stepchild, grandchild parent, stepparent, or someone you have resided with for at least two years. Anything above the maximum threshold will trigger a 15% gift tax.

    How do I go about calculating my crypto tax?

    Calculating your cryptocurrency tax involves several steps, from identifying taxable events determining the applicable tax rates, and reporting the information accurately. Here’s a step-by-step guide to help you calculate your crypto tax:

    1) Identify Taxable Events; such as:

    • Sales: Selling cryptocurrency for fiat currency (e.g., DKK).
    • Exchanges: Exchanging one cryptocurrency for another.
    • Purchases: Using cryptocurrency to buy goods or services.
    • Mining and Staking: Receiving cryptocurrency as a reward for mining or staking.
    • Airdrops and Forks: Receiving cryptocurrency from airdrops or blockchain forks.

    2) Determine the Fair Market Value (FMV)
    For each taxable event, determine the cryptocurrency’s fair market value in Danish kroner (DKK) at the time of the event. This information can typically be found on your exchange or through cryptocurrency price-tracking websites.

    3) Calculate Capital Gains or Losses
    Capital Gains: Subtract the acquisition cost (purchase price plus any transaction fees) from the selling price or the fair market value at the time of exchange or use.
    Capital Losses: If the acquisition cost is higher than the selling price or the fair market value at the time of exchange or use, this results in a capital loss.


    Capital Gain/Loss = Selling Price/FMV − Acquisition Cost

    4) Report Income from Mining and Staking                                                          Report the value of the cryptocurrency received from mining or staking as income. Your taxable income should include the fair market value at the time of receipt.

    5) Track All Transactions
    Maintain detailed records of all cryptocurrency transactions, including dates, amounts, transaction fees, and the value in DKK at the time of each transaction. Tools like cryptocurrency tax software can help automate this process.

    6) Apply Tax Rates
    Capital Gains Tax: Apply your marginal tax rate to the net capital gains. In Denmark, marginal tax rates can range from 37% to 52%, depending on your total income.
    Income Tax: Apply your marginal tax rate to income from mining, staking, airdrops, and forks.

    7) Offset Capital Losses
    Capital losses can offset capital gains within the same tax year. If you have more losses than gains, you may be able to carry forward the losses to future tax years, taking the above mentioned specifications into consideration.

    8) Complete Tax Reporting
    Report all capital gains, losses, and cryptocurrency-related income on your annual tax return. In Denmark, this is typically done using the online tax platform provided by the Danish Tax Agency (Skattestyrelsen).


    Navigating the tax implications of cryptocurrency in Denmark requires a thorough understanding of the detection methods used by the Danish Tax Agency and the specific tax rules that apply to various crypto activities. Danish authorities have multiple tools to uncover unreported crypto assets, from exchange reporting and blockchain analysis to self-reporting requirements. Correctly calculating and reporting crypto-related income and capital gains is essential to avoid penalties and ensure compliance with Danish tax laws. As the regulatory landscape evolves, staying informed about the latest requirements and seeking professional advice can help taxpayers manage their cryptocurrency investments responsibly.
