Crypto Taxes in Sweden 2026 – Skatteverket Complete Guide

Sweden taxes cryptocurrency under clear rules from Skatteverket. This guide covers the 30% capital gains tax, how crypto-to-crypto trades are handled, and how to file form K4.

How Sweden Taxes Cryptocurrency

Swedish tax authority Skatteverket classifies cryptocurrency as an other asset (övriga tillgångar). Gains are subject to capital gains tax in the Inkomst av kapital (capital income) category. The standard rate is 30% on net capital gains.

Capital Gains Tax Rate

Sweden applies a flat 30% tax on capital gains from crypto. There is no holding period exemption – whether you held for 1 day or 10 years, the rate is 30% on net gains. However, capital losses can offset capital gains, and 70% of net losses can be deducted against other capital income.

Crypto-to-Crypto Trades Are Taxable

A key aspect of Swedish crypto taxation: trading one cryptocurrency for another is a taxable disposal. You must calculate the SEK value of both the crypto you gave up and the crypto you received at the time of the trade, and report the gain or loss. This creates reporting obligations every time you swap tokens, even on a DEX.

Average Cost Basis Method

Sweden uses the average cost method (genomsnittsmetoden). Each time you buy a cryptocurrency, your total cost is averaged across all units held. When you sell, the gain is: Proceeds minus (Units Sold × Average Cost per Unit). This is recalculated after every purchase.

Schablonmetoden (Standard Deduction Method)

As an alternative to the average cost method, Swedish taxpayers can use the schablonmetoden: assume that 20% of the proceeds represent the cost basis. This means you pay tax on 80% of the proceeds at 30% – an effective rate of 24%. This simplifies calculations but is only beneficial when your actual cost basis is less than 20% of proceeds (i.e., gains exceed 80% of sale price).

Mining, Staking, and Airdrops

Crypto received as mining income or staking rewards is taxable as income from other sources (inkomst av tjänst) at progressive rates up to ~52%. The same value becomes the cost basis for future disposals. Airdropped tokens with a determinable market value are also taxable income when received.

Filing with K4 Form

Report crypto gains on the K4 form (Värdepapper m.m. – Securities etc.), specifically in Section D for other assets. The K4 is filed as part of your annual tax return (Inkomstdeklaration). The filing deadline is typically May 2. Crypto tax software can generate a completed K4 form compatible with Skatteverket's requirements.
