Between March 18 and May 2, it's time to file your tax return in Sweden. In your declaration, it's essential to report if you have sold, exchanged, or used cryptocurrency for payments. If you made a profit, you must pay taxes on it, and if you incurred a loss, you can deduct part of it. This step-by-step guide explains how to declare Bitcoin and cryptocurrencies according to the Swedish Tax Agency (Skatteverket), common mistakes to avoid, and how to simplify your tax declaration using automated crypto tax services.

How Are Cryptocurrencies Taxed in Sweden?
In Sweden, cryptocurrencies are considered taxable assets rather than currencies. Every time you sell, trade, or use crypto for payments, you must calculate a capital gain or loss. Capital gains are taxed at 30%. Losses can be deducted at 70% against crypto profits. Every disposal is taxable, even exchanging one cryptocurrency for another or using Bitcoin for purchases. Understanding these crypto tax rules helps you avoid costly mistakes when filing your taxes.
Step-by-Step Guide: How to Declare Cryptocurrencies
1. Gather Your Transaction History
Retrieve your crypto transaction data from all platforms where you have traded. If you use BTCX, you’ll find all necessary transaction details in your account. Most crypto exchanges allow you to export a list of your buy, sell, and trade history.
Key data to collect:- Transaction dates
- Type of cryptocurrency
- Amount bought or sold
- Purchase and sale price
- Any fees paid
2. Calculate Gains and Losses
Use the average cost method to determine the acquisition cost of your cryptocurrencies. Capital gain/loss = Sale price - Average acquisition cost. Profits are taxed at 30%. Any losses can be deducted at 70% against any crypto gains made during the year. This step is crucial for accurate Bitcoin taxation and ensuring compliance with Swedish tax laws.
3. Report to the Swedish Tax Agency
Fill in Appendix K4, Section D of your Swedish tax declaration. Here, you can report your total capital gains and losses from your crypto transactions. Make sure that all your information is correct and that you have the documentation needed in case Skatteverket requests a verification.
4. Pay Tax on Your Crypto Profits
Check the tax payment deadline and available payment methods. Timely crypto tax payments help you avoid penalties. If you cannot pay the full tax amount, you can contact the Swedish Tax Agency to set up a payment plan.
