Cryptocurrency in Finland: 30% on gains and the deemed cost rule
In short. Finland charges 30% on your crypto gain and 34% on the part above 30,000 euros, treating it as capital income rather than salary. The rule worth knowing is the deemed acquisition cost: instead of your real purchase price you may claim 20% of the sale price as cost, or 40% if you held for more than ten years. Vero lets you take whichever leaves you less gain.

Thirty percent, thirty-four above the line
A crypto disposal produces capital income in Finland, kept apart from the progressive scale that applies to wages. The first 30,000 euros of capital income in a year meets 30%, and anything above that meets 34%.
Keeping it out of the wage scale matters. A Finn on a high salary pays the same 30% on a small crypto gain as someone earning nothing, where in Denmark the same gain would stack on top of the salary.
Losses count against capital income. Sell one position at a profit and another at a loss in the same year, and the two meet before the rate applies.
The deemed cost, and when it beats your receipts
Finnish law offers a second way to compute the cost of what you sold. Rather than proving what you paid, you may treat 20% of the sale price as your acquisition cost, or 40% if you owned the asset for more than ten years.
Do the arithmetic on a coin bought at 100 euros and sold at 1,000. Real cost gives a gain of 900 and tax of 270. The deemed cost puts your cost at 200, the gain at 800, and the tax at 240.
The deemed cost wins whenever your real purchase price was under a fifth of the sale price, which covers anyone who bought early and held. Vero expects you to pick, and picking the better of the two is allowed.
Keep the receipts anyway. On a position that moved little, the real cost is the one that helps.
FIFO, and a reporting change in 2026
Where you hold the same coin bought at different times, Finland matches disposals first in, first out. The oldest units leave first, carrying the oldest cost.
From the 2026 tax year the return changes shape. The return now splits gains and losses by whether a Finnish or a foreign service provider handled the trade, and asks for acquisition costs, sale prices and results as totals for the year rather than trade by trade.
Anyone using an exchange outside Finland should sort their records along that line before the filing season.
Six months, and what it cost
Finland gave existing crypto firms six months to obtain MiCA authorisation, the shortest window any member state chose. It closed on 30 June 2025, when most of the EU still had a year to run.
Five providers now hold Finnish authorisation, against twenty-three in Malta and thirteen in Luxembourg. The short runway is part of that gap: firms that could not be ready in six months went to a regulator that gave them eighteen, and a licence from any member state serves Finnish customers.

The return separates Finnish from foreign service providers.
Worth knowing
Finland gave crypto firms six months to move onto MiCA, where Malta, Denmark and Luxembourg allowed eighteen. The window closed on 30 June 2025, a full year before the EU-wide deadline.
Common questions
What rate applies to my gains?
30% as capital income, and 34% on the part above 30,000 euros a year.
What is the deemed acquisition cost?
A substitute for your real purchase price: 20% of the sale price, or 40% if you held the asset over ten years. You take whichever leaves the smaller gain.
Can I deduct losses?
Yes, against your capital income in the same year.
Which units count as sold first?
The oldest ones. Finland applies first in, first out.
Why do so few firms hold a Finnish licence?
Finland allowed six months to transition where most of the EU allowed eighteen, and a licence from any member state serves Finnish customers.
