Crypto regulation in Sweden
Last updated: 2 May 2026
At a glance
- MiCA applicable: ✓ Yes (since 2024-12-30)
- Competent authority: Finansinspektionen (FI)
- Capital-gains rate: 30%
- Tax filing: Skatteverket Form K10/K4
- Advertising policy: The strictest in the EU — even mandatory warning labels
1. Finansinspektionen — a supervised market
Sweden’s financial supervisor Finansinspektionen (FI) is conservative when it comes to crypto services. Before MiCA, FI actively stated that crypto investments “are not appropriate for retail investors in most cases”, and issued multiple warning letters.
Since MiCA came into force, FI has been licensing CASPs but with particularly thorough checks. Registry: fi.se/en/our-registers.
2. The strictest crypto-advertising regime in the EU
Sweden applies one of the strictest crypto-advertising regimes in the EU market:
- Before publishing an ad, the operator must keep documentationsubstantiating every claim
- An ad must contain a clear warning about the high risk
- Crypto ads suggesting potential earnings without context are prohibited
- Konsumentverket (the Consumer Agency) actively issues warnings and sanctions
Large global exchanges (Bybit, MEXC, Binance) have received Swedish FI warnings for unauthorised advertising — for that reason many of them currently restrict Swedish customer registration.
3. Taxes — Skatteverket
3.1. Capital-gains rate
In Sweden, capital gains (including crypto) are taxed at a flat 30% rate. That is high compared with Latvia’s 20% and Lithuania’s 15–20%, but lower than Denmark’s (up to 52%).
Unlike Latvia, Sweden has no tax-free allowance for crypto capital gains — every SEK is taxed from the first.
3.2. Filing
Skatteverket Form K10 (or K4 in some cases) is used for filing crypto capital gains. Available through the Skatteverket digital portal.
Deadline: 2 May for the previous calendar year.
3.3. Tools
Both Divly and Koinly offer automated generation of Skatteverket K10. Divly is a Sweden-based company and therefore has deeper local specifics.
4. The biggest SE-based crypto operators
- Kvarn X (Kvarn AB) — pre-MiCA VASP, MiCA application pending — review
- Trijo — a smaller exchange focused on Swedish consumers
- Safello — a historical Swedish exchange, the first to receive FI authorisation
- BTCX — historical; activity is limited today
