Forex Trading Tax in Finland 2026 — Complete Guide

Forex Tax Treatment in Finland

Forex trading profits are taxed as capital income at 30% on gains up to EUR 30,000 and 34% on gains exceeding that threshold. Losses from forex trading can be offset against other capital income for the same tax year and carried forward for 5 years.

Forex and CFD gains are paaomatulo (capital income), separate from earned income (ansiotulo).

What Counts as Taxable?

Most Finland residents need to declare the following types of trading income:

• Realised forex/CFD capital gains. Profits from closing positions during the tax year.
• Dividend-equivalent payments. Cash adjustments paid by your broker on long share-CFD positions when the underlying issues a dividend.
• Carry / swap interest received. Positive overnight financing credited to long carry-trade positions is normally taxable as financial income.
• Cashback, rebates and bonuses. Cash incentives paid by the broker may be reportable as miscellaneous or financial income.
• Crypto CFD profits. Profits from cryptocurrency CFDs are taxed under the same rules as other CFDs (this is different from spot crypto, which usually has its own treatment).
• Foreign exchange differences. Gains or losses from holding foreign-currency balances may need to be reported separately when converted back to your home currency.

Professional vs Retail Trader — Tax Implications

If trading is conducted as elinkeinotoiminta (business activity), profits move to ansiotulo at progressive rates plus mandatory entrepreneur insurance (YEL).

How to Declare Forex Income in Finland

1. 1

   Download your annual statement from each broker (and convert all amounts to EUR using year-end FX rates if your account is in another currency).

2. 2

   Calculate net realised profit or loss for the tax year — buy/sell pairs only (unrealised positions are usually excluded, except for mark-to-market regimes).

3. 3

   Add carry/swap interest, dividend-equivalent payments, and any cashback or rebates.

4. 4

   Open Esitaytetty veroilmoitus (pre-filled tax return) on the Verohallinto (Finnish Tax Administration) portal.

5. 5

   Enter the totals in the capital-gains / investment-income section and indicate the source country of each broker.

6. 6

   Pay any balance owed by the deadline (Mid-May of the following year (date varies by taxpayer)) and keep the receipt and broker statements with your records.

Recommended Accountants & Software

Use the OmaVero portal. A tilintarkastaja (auditor) or verokonsultti is recommended for active traders with significant foreign-broker volume.

We do not endorse any single product. For active traders we generally recommend a local advisor who has direct experience with CFD/derivative reporting and any cross-border passporting that applies to your broker.
