The basics of Bitcoin tax in Finland
In Finland, Bitcoin is treated like any other property for tax purposes.
A gain from selling or swapping Bitcoin is taxable capital income, and it is reported to the Finnish Tax Administration as a capital gain.
A taxable event arises when Bitcoin is disposed of, not when you simply buy or hold it.
This principle often surprises beginners: a rise in the value of Bitcoin in your wallet does not in itself have tax consequences, however much the value has grown.
Tax becomes payable only when you decide to realise the gain by selling, swapping or spending Bitcoin.
Bitcoin tax rate in Finland
A capital gain from Bitcoin is taxed in Finland as capital income on the same progressive capital income scale as other capital gains, such as gains on shares. In 2026 the rate is 30% on capital income up to €30,000 a year and 34% on the part above that.
Rates and thresholds can change from year to year, so always check the current figures on the Tax Administration's website before filing your tax return.
What counts as disposing of Bitcoin?
- Selling Bitcoin for euros. The clearest and most common disposal.
- Swapping Bitcoin for another cryptocurrency. A crypto-to-crypto swap is also a disposal for tax purposes, even though nothing is converted into euros.
- Paying with Bitcoin. Buying goods or services with Bitcoin counts as a disposal of the Bitcoin used.
Tax practice can become more precise over time, and individual cases vary. This page is general information, not personal tax advice.
The Finnish Tax Administration publishes its own, regularly updated guidance on the taxation of crypto-assets. In more complex situations, such as extensive trading, mining or staking, consider consulting a tax professional.
How is the capital gain on Bitcoin calculated?
The capital gain is calculated by deducting the acquisition cost (purchase price plus fees) from the sale price, or alternatively the deemed acquisition cost if it is more favourable or the purchase price cannot be shown (Finnish Tax Administration). The deemed acquisition cost is 20% of the sale price, or 40% if you have held the Bitcoin for at least 10 years.
| Situation | Tax treatment |
|---|---|
| Gain on sale | Taxable capital income |
| Loss on sale | Deductible from other capital gains under certain conditions |
| Crypto-to-crypto swap | Taxable disposal, even without converting to euros |
| Holding Bitcoin without selling | No taxable event |
How to report Bitcoin in your Finnish tax return
- Keep a record of every trade. Purchase date and price, sale date and price, and the service used.
- Calculate the gain or loss for each sale separately. Most exchanges provide an annual transaction report, but check that it is complete.
- Report your sales in MyTax (OmaVero) under capital income, capital gains, with crypto-assets as the asset type. You can report sales one by one or the whole year at once; when reporting at once, attach a breakdown of all sales, and report profitable and loss-making sales as separate calculations.

Why good record-keeping should start right away
Many beginners make the mistake of starting to work out their purchase history only when the tax return is due, when the information can be hard to put together afterwards, especially if you have used several services or moved funds between wallets.
From the start, keep a simple spreadsheet of every trade: date, amount, price in euros and the service used.
- Save receipts and confirmations at the time of purchase. Don't rely on the exchange keeping the data forever.
- Record transfers between wallets too. A transfer between your own wallets is not a taxable event, but it helps trace where your funds came from.
- Use a crypto tax tool if needed. Especially if you have many trades or several services.
Special situations to keep in mind
| Situation | Keep in mind |
|---|---|
| Bitcoin received as a gift | May be subject to gift tax; the acquisition cost is usually the value confirmed in gift taxation |
| Inherited Bitcoin | May be subject to inheritance tax; the acquisition cost is the value confirmed in inheritance taxation |
| Bitcoin mining | Mined Bitcoin is earned income at its value when received (Finnish Tax Administration) |
| Moving to or from Finland | Your tax liability depends on your tax residence; check your own situation separately |
These situations are often more complex than an ordinary purchase and sale, and it is worth considering a tax professional to reduce the margin of error.
Bitcoin tax in Finland: frequently asked questions
Do I pay tax when I buy Bitcoin in Finland?
No. Simply buying or holding Bitcoin is not a taxable event. Tax only comes into play when you sell, swap or spend it.
Can I deduct a Bitcoin loss in Finnish taxation?
Yes. A loss is deducted first from capital gains and then from other capital income, and any part not deducted carries forward for the next five years. The rules and exceptions are covered in our guide to deducting losses.
Do I need to report a crypto-to-crypto swap separately?
Yes. Even if you don't convert Bitcoin into euros, a swap into another cryptocurrency counts as a disposal and must be reported.
What if I haven't reported earlier trades?
Correct the missing information as soon as possible, for example by correcting your tax return yourself in MyTax. The consequences of an omission are usually smaller when you deal with it actively yourself.
Does moving Bitcoin between my own wallets affect taxation?
No. Moving Bitcoin from your own wallet or exchange account to another wallet of your own is not a disposal for tax purposes, because ownership does not change.
