Cómo declarar criptomonedas en Suecia
Sweden applies a very clear model: each sale or exchange of cryptocurrencies is declared transaction by transaction in annex K4, and the gain is taxed at 30%. Skatteverket receives data from Nordic and European platforms, so traceability is high.

Annex K4 and average cost
Sweden uses the weighted average cost method (genomsnittsmetoden): each purchase updates the average acquisition price of that cryptocurrency, and the gain is calculated by subtracting that average cost from the sale amount expressed in kronor.
Each type of crypto asset is declared on a separate line in annex K4, indicating the number of units sold, the amount received, and the acquisition cost. For many transactions, it is advisable to use tax software that automatically generates the K4.
Mining, staking, and losses
Mining and staking rewards are valued in kronor on the day they are received. If the activity is regular and organized, Skatteverket may consider it an economic activity (näringsverksamhet) with different rates.
Losses are only 70% deductible: if you lose 10,000 SEK, you can deduct 7,000 SEK against other capital income, which reduces the final tax for the year.
Before filing: have your history in order
The first step to a proper tax declaration is to download the complete transaction history from each platform you use. MiCA-licensed exchanges often provide ready-to-use annual reports, which significantly simplifies the filing process.
