Crypto tax in Sweden 2026
Sweden taxes crypto as capital income: 30% flat on gains from selling, swapping or spending coins, computed per disposal with the average-cost method and reported on form K4.
Losses bite at only 70% of their value against other capital income — so heavy churn in a flat market still creates net tax.

Thresholds & allowances
- No de-minimisEvery disposal is reportable
The tax agency receives exchange data under EU-wide reporting from 2026
Residency

Non-resident treatment
Non-residents are outside Swedish tax on personal crypto gains.
Notes
- The source chapter does not address crypto; the treatment follows the tax agency's published position — capital income at 30%, K4 reporting — flagged accordingly.
- Swaps count as disposals: trading one token for another crystallises a gain or loss in kronor.
- The 70% loss rule makes loss-harvesting less potent than in symmetric systems — netting within the same year still helps.
- Interest-like crypto yields (lending) are taxed as capital income when received.
FAQ
How is crypto taxed in Sweden?
At the flat 30% capital-income rate on every disposal — sales, swaps and purchases with crypto — using average cost, reported on form K4. Losses offset at only 70% of value.
Can I hold crypto in a Swedish ISK to avoid tax?
No — the investment savings account accepts listed securities and funds, not crypto, so coins stay under the ordinary 30% regime.
