📝 Description
In Sweden, cryptocurrency taxation is managed very strictly and clearly by the Swedish Tax Agency (Skatteverket). Cryptocurrencies are considered "Other Assets" and are subject to capital gains tax.
The Swedish system has unique characteristics, particularly regarding the calculation of your purchase price and the deduction of losses. This guide explains the Swedish legislation for individuals and how to use Waltio to generate a perfectly compliant report.

💰 Calculation and Tax Rates
In Sweden, the tax on cryptocurrencies is a flat capital gains tax set at 30%.
📈 The Average Price Method
Sweden mandates the Average Price method (Genomsnittsmetoden). You must calculate the average purchase price of all your tokens for a specific cryptocurrency to determine your profit upon sale.
📉 The Strict 70% Rule for Capital Losses
If you realize a capital gain, it is taxed on 100% of its amount. However, if you realize a capital loss, only 70% of that loss is deductible from your capital gains in the same year.
Example: If you lose 1,000 SEK on a Bitcoin sale, you can only use 700 SEK to reduce your other taxable capital gains.
Rest assured, Waltio’s calculation engine takes your operations into account to help you extract the data needed to fill out your tax return.
🔄 Crypto-to-Crypto Operations (Trading)
The Swedish tax administration (Skatteverket) is categorical: exchanging one cryptocurrency for another (for example, selling Solana to buy USDT) is a tax-triggering event. This is equivalent to selling your Solana for Swedish Krona (SEK) and immediately buying USDT.
⚙️ How are they managed on Waltio?
Great news: Waltio’s behavior is perfectly aligned with Swedish law. The software automatically considers each Crypto-to-Crypto exchange as taxable and calculates the capital gain (or loss) realized at the time of the swap.
Your process: You have no manual action to perform for these operations. The tool will process your trades exactly as required by the Swedish tax administration.
🎁 Passive Income (Staking, Mining, Airdrops)
In Sweden, income from mining, staking, or airdrops is generally considered income from employment or capital at the exact moment of receipt. The taxable value is the market price of the token (converted to SEK) on the day you receive it in your wallet.
⚙️ How are they managed on Waltio?
To ensure simplified global tracking, Waltio applies a different default methodology:
Passive income is marked as non-taxable upon receipt.
The software assigns them an acquisition value of €0.
Practical consequence: Taxation is deferred. It is only when you decide to sell these tokens (for another crypto or fiat) that the operation becomes taxable. The entire disposal amount will then be considered a taxable capital gain at 30%.
To have tax accounted for upon receipt (Strict Compliance):
If you wish to report this income at the time of receipt in the current year (to follow Skatteverket’s basic rule), a manual step is required on Waltio. You will need to individually modify each passive gain transaction to enter its acquisition price (i.e., the market price of the token on the exact day of receipt). This way, the acquisition value will no longer be €0, and the operation will be isolated as immediate income. This value will then become the acquisition cost for your future sales.
✅ What triggers tax (Crypto ➔ Fiat)
In addition to crypto-to-crypto exchanges, classic exit operations to the real economy trigger the 30% capital gains tax:
Sale for currency: Converting your cryptos into Swedish Krona (SEK), Euro (EUR), etc.
Purchase of a good or service: Paying for a purchase with a crypto card is considered a sale.
Payment for a lending service: Transferring ownership of your tokens to lend them may also constitute a disposal in Sweden.
📝 Filing: Calendar and K4 Form
Tax Period: January 1st to December 31st.
Required Form: Gains and losses must be declared in detail via the K4 annex (Section D) of your income tax return.
Filing Deadline: The declaration must generally be submitted by early May of the following year (the exact date is often around May 2nd or 3rd on the Skatteverket online portal).
