When do you become tax resident in Finland?
According to the Finnish Tax Administration, if you stay in Finland for more than six months, you are taxable in Finland on income you receive from Finland and from abroad. A person whose permanent home is in Finland is also a resident taxpayer. If you live abroad, you are taxable in Finland only on income from Finland.
For crypto this means: once you are a resident taxpayer, capital gains from selling or swapping crypto are taxable in Finland, wherever the exchange or wallet is located. If you are also considered resident in another country, the tax treaty between Finland and that country determines which country has the primary right to tax.

Crypto bought before moving to Finland
Finnish tax is triggered when you dispose of crypto: sell it for euros or another currency, swap it for another crypto or use it to pay for something. Buying or simply holding crypto is not taxable. So crypto you bought abroad and brought with you is not taxed on arrival, but a later sale while you are resident in Finland is taxed in Finland.
The gain is calculated as the sale price minus the acquisition cost. For crypto bought before moving, keep records of the original purchase price, date and fees. Alternatively you can always use the deemed acquisition cost: 20% of the sale price, or 40% if you have held the crypto for at least 10 years. You can choose whichever is more favourable, and the deemed cost is useful if you can no longer prove what you paid. The details are in our main guide to crypto taxes in Finland.
Worked example: selling crypto bought before moving
The example is hypothetical. You bought 0.5 BTC for €8,000 before moving to Finland and sell it as a Finnish resident for €30,000. With the actual acquisition cost the gain is €22,000. With the deemed acquisition cost (20% of €30,000 = €6,000) the gain would be €24,000, so the actual cost is better here. Capital income tax is 30% up to €30,000 a year, so the tax would be €6,600 if you had no other capital income or losses.

How expats report crypto in Finland
Crypto gains are reported in the pre-completed tax return in MyTax (OmaVero) under capital gains, with crypto-assets as the asset type. Crypto gains are usually not pre-filled, so you have to add them yourself.
- Logging in to MyTax: MyTax normally requires Finnish online banking credentials or a mobile certificate. If you don't have them yet, the Tax Administration offers alternatives, including paper forms. See MyTax and the Tax Administration's forms.
- Records from foreign exchanges: download full transaction histories from every exchange you have used, including ones in your previous country. Exchanges can close or restrict access, as happened to EU users of Binance in 2026.
- Software: if you have many transactions across several exchanges, a crypto tax tool that supports Finnish rules can help; see our Divly review.
Leaving Finland later
If you later move away, your Finnish tax liability depends on whether you remain a resident taxpayer. Finnish citizens who move abroad are generally still treated as resident for the year of departure and the following three years unless they can show they no longer have essential ties to Finland. For foreign nationals, the general residence rules apply. Check your own situation with the Tax Administration before selling large amounts around a move.
Crypto taxes for expats in Finland: frequently asked questions
Do I pay Finnish tax on crypto I bought before moving to Finland?
Not when you arrive, because holding crypto is not taxable. But if you sell or swap it while you are a resident taxpayer in Finland, the gain is taxed in Finland, calculated from the original acquisition cost or the deemed acquisition cost.
I can't prove what I paid for my crypto. What can I do?
You can use the deemed acquisition cost: 20% of the sale price (40% if held for at least 10 years). It is always available to individuals, and it is especially useful when records from old or closed exchanges are missing.
Do I need to report crypto held on a foreign exchange?
Finland doesn't tax holding crypto, so there is no separate wealth report for it. You report the gains and losses when you sell, swap or spend crypto, regardless of where the exchange is located.
What if my previous country also taxes the same gain?
The tax treaty between Finland and that country determines which country taxes the gain and how double taxation is removed. Treaties differ, so check the specific treaty or ask the Tax Administration if both countries could consider you resident.
