Sweden -- Cryptocurrency Tax Framework Regulatory Overview

In Sweden, cryptocurrencies are taxed under general income tax principles as "other assets" (Chapter 52 of the Income Tax Act), with no specific crypto legislation, primarily subject to a flat 30% capital gains tax on disposals, plus income tax or interest income tax depending on the activity.[1][2][3][6]

Capital Gains Tax

Cryptocurrency disposals (sales, trades, or use for payments/services) trigger capital gains tax at a flat 30% rate on profits, calculated via the average cost basis method (Genomsnittsmetoden).[1][2][4][5][6] Losses allow a 70% deduction against gains.[2][4] This applies to individuals' casual trading; business-held crypto may be taxed as business income.[3][6]

Income Tax on Crypto

• Mining rewards or crypto earned as wages/compensation (e.g., referrals) are taxed as regular income at progressive rates: municipal tax (varies by location) plus national tax (above ~598,500 SEK threshold), averaging ~32% for most, up to 52%.[1][2][4][7]
• Later disposal of such crypto uses the income-declared value as cost basis for capital gains.[2]

Interest Income Tax

Staking rewards, lending interest, or similar are taxed at a flat 30% as interest income.[1][2]

VAT/GST Treatment

• Crypto-to-fiat exchanges are VAT-exempt.
• Payments in crypto for goods/services are treated as legal tender equivalents (VAT applies to underlying supply).
• Mining revenue is generally outside VAT scope.[3]

Reporting Requirements

Individuals file via annual tax return (Inkomstdeklaration 1) by May 2 (extensions to May 16/31 possible); tax year is Jan 1–Dec 31.[1][4]

• K4 form (Section D): Capital gains/losses from disposals.[4][8]
• T2 form: Mining/reward income.[4]
• Section 7.2: Staking/interest income.[4]

Businesses report under business income rules; companies pay 21.4% corporate tax on crypto profits if classified as such. VAT registration required if applicable (monthly/quarterly/annual returns); annual Inkomstdeklaration 2.[3][5][8] Crypto-asset service providers (CASPs) report under DAC8/CARF to Skatteverket for EU exchange (not taxpayer-filed).[4]
