Introduction
Finnish crypto tax is simpler than it looks, as long as you grasp one key idea: in Finland, your crypto gains are not "ordinary" income like a salary, but capital income. And that capital income follows a two-tier scale: 30% up to a certain threshold, then 34% above it. No magic tied to how long you hold: holding for a long time does not erase the tax. This module walks you through that scale, the €30,000 threshold, how the gain is computed, and how you declare to Vero. Important: this content is educational, not personal tax advice — for your own situation, consult an accountant or tax adviser.
The principle: capital income, 30% then 34%
In Finland, crypto gains are treated as capital income. So it is not a single rate applied to everything: it is a two-tier scale, depending on your total capital income for the year.
Up to €30,000 of capital income per year, the rate is 30%. This is the first tier, the one that applies to most individuals.
Above €30,000 of capital income for the year, the portion exceeding that threshold is taxed at 34%. Only the part above €30,000 moves to the higher rate, not the whole amount.
Another essential point: there is no holding-period exemption. Holding your crypto for one year or five years does not change the rule — the gain remains taxable.
- Crypto gains are capital income.
- 30% up to €30,000 of capital income per year.
- 34% on the portion above €30,000.
- No holding-period exemption.
In Finland, a single flat rate applies to all crypto gains.
Actually : No. The rate is 30% up to €30,000 of capital income per year, then 34% on the portion above €30,000. It is a two-tier scale, not a single rate.
The €30,000 threshold: how it works
The €30,000 threshold does not apply only to your crypto gains: it is assessed across all your capital income for the year (capital gains, but also other capital income). It is this annual total that determines where you move from 30% to 34%.
The mechanism is progressive: only the part above €30,000 is taxed at 34%. The part below it stays at 30%. So you do not "lose" anything by crossing the threshold — only the excess is affected.
- The €30,000 threshold is assessed across all your capital income for the year, not just crypto.
- Up to €30,000 of capital income: 30%.
- On the portion above €30,000: 34%.
- Only the excess moves to 34%; the part below the threshold stays at 30%.
Computing the gain (sale price − acquisition cost)
The taxable gain is computed simply: sale price minus acquisition cost. If you sell a crypto for more than you paid for it, the difference is your taxable gain.
So it is the difference between what you receive on the sale and what you paid to acquire it that is taxed — not the total sale amount.
To be able to justify this calculation, keeping your records is essential: dates and amounts of purchase, dates and amounts of sale, any fees. Without these, you cannot prove your acquisition cost to the authorities.
Keep your supporting records
Gain = sale price − acquisition cost. To demonstrate it, keep the history of your operations: dates and amounts of purchase and sale. Without a justified acquisition cost, you cannot prove your real gain to Vero.
Declaring to Vero, and the role of a French account
In Finland, it is up to you, the resident, to declare your crypto gains yourself to Vero (the Finnish Tax Administration). You report your gains as capital income, which will be taxed at 30% up to €30,000, then at 34% above it.
Deblock is regulated in France, not in Finland. That changes nothing about your obligation: the account does not declare on your behalf and removes no Finnish tax obligation. As a Finnish resident, it is up to you to compute your gains and declare them to Vero.
The right reflex remains to keep the history of your operations (dates, amounts) to justify your acquisition cost, and, at the slightest doubt, to consult an accountant or tax adviser. Official source: Vero.fi (the Finnish Tax Administration).
- You declare your gains yourself to Vero, as capital income.
- Deblock, regulated in France, never declares on your behalf.
- Keep the history of your operations (dates, amounts) to justify your acquisition cost.
- At the slightest doubt, consult an accountant or tax adviser.

Crypto tax by country
How your crypto gets taxed at home
Every country where Deblock is available has its own tax reading. This section gives an educational reference point before any simulation. Your real case depends on tax residence, annual transactions and your status.
France: 30% flat tax with €305 disposal exemption
For a French tax resident, selling crypto for euros, paying with crypto or converting into a good/service triggers taxation. Crypto-to-crypto swaps are generally neutral.
Simplified calculation
- If annual disposals ≤ €305: no tax.
- Gain = disposal price − weighted total acquisition price across the portfolio.
- 30% flat tax by default: 12.8% income tax + 17.2% social contributions.
- Optional progressive income tax scale if more favourable.
