Swedish Capital Gains Tax Guide 2026

Overview of CGT in Sweden

Capital gains in Sweden are classified as capital income (kapitalinkomst), which is taxed separately from earned income. The standard rate is a flat 30%. Unlike many countries, Sweden does not have a distinction between short-term and long-term capital gains for shares — the 30% rate applies regardless of holding period. However, property gains use the 22/30 rule (see below) and lottery bonds have a special short-term rule. Capital losses may be deductible, but the deduction amount depends on the asset type.

Shares and Funds — 30%

Capital gains on listed shares (aktier) and fund units are taxed at a flat 30% on net gains. The gain is calculated as the selling price minus the acquisition cost (including brokerage fees). The acquisition cost can be determined using the average cost method (genomsnittsmetoden), schablonmetoden (20% of proceeds), or specific identification if you can track individual lots.

• Schablonmetoden (simplified method): For listed shares held for more than one year (but the holding period condition is rarely enforced in practice), you can use 20% of the proceeds as the acquisition cost. This is often beneficial for shares with very low original cost bases.
• Loss offset on shares: 70% of share losses are deductible against share gains in the same year. If total share transactions result in a net loss, 70% of that loss offsets other capital income. If capital income remains negative, the loss generates a tax credit at 30% on 70% of the loss = 21% effective benefit.
• Funds: ETF units and mutual funds are treated the same as shares. Automatic reporting of gains and losses is provided by the bank/fund company on the K4 form.

Property — 22/30 Rule (22% Effective)

Capital gains on residential property sales follow the 22/30 rule:

• Only 22/30 (73.3%) of the actual gain is taxable
• The taxable portion is taxed at 30% in the capital income category
• Effective tax rate: 22% (30% × 22/30)
• Losses: 63% of a property loss is deductible against other capital income. For losses, 63% × 30% = 18.9% effective benefit.

Allowable costs when calculating a property gain: purchase price, stamp duty (lagfart), renovation costs (ömkostnader — capital improvements that add value), and selling costs (real estate agent fees, marketing, legal). Maintenance and routine repairs are not added to the cost basis but may be deductible in other ways.

A deferral (uppskov) is available if you buy a more expensive replacement property. The deferred gain generates a schablonintäkt of 3.25% per year, taxed at 30% (effective 0.975% per year on deferred amount). See the property tax guide for more details.

Holding Period Distinction

For standard shares and funds, there is no holding period distinction — all gains are taxed at 30% regardless of how long you hold. The only exception is lottery bonds (premieobligationer): if held less than 1 year, gains are taxed at 27% (not 30%). After 1 year, the standard 30% rate applies. This is a minor anomaly in the Swedish tax code. ISK accounts (see the investment income guide) eliminate the need to track holding periods entirely by taxing a deemed return instead of actual gains.

Crypto Gains — 30%

Cryptocurrency gains are taxed as capital income at 30% (kapitalinkomst). Skatteverket treats each cryptocurrency as a separate asset class. Key rules:

• Cost basis: You may use the average cost method (genomsnittsmetoden) across all units of the same cryptocurrency, or specific identification if you have detailed records of each coin/token.
• Schablonmetoden: For crypto, the simplified 20% of proceeds method is available but generally less favourable due to crypto's high volatility and recent price increases.
• Trading pairs: Each trade between two cryptocurrencies (e.g., BTC to ETH) is a taxable event — you must calculate the gain in SEK on the disposed cryptocurrency.
• Mining and staking: Rewards from mining and staking are taxed as earned income (tjänsteinkomst) at the time of receipt, then subject to CGT on subsequent disposal.
• Losses: Crypto losses are 70% deductible (same as shares). A net capital loss on crypto reduces capital income. If capital income is insufficient, the excess loss creates a tax credit at 21% (30% of 70%).
• Reporting: All crypto transactions must be reported on the K4 form (blankett K4) attached to the Inkomstdeklaration. Skatteverket can request detailed transaction histories from exchanges.

Business Shares — Qualified vs Non-Qualified

Shares in closely held companies (fåmansföretag) are subject to special rules under the 3:12 rules. For qualified shares (kvalificerade andelar):

• Part of the gain is taxed as earned income (tjänsteinkomst) — up to ~57% marginal rate
• The remainder is taxed as capital income at 30%
• The split depends on the salary base, share capital, and the "normal amount" calculation
• Non-qualified shares (onoterade andelar not in a fåmansföretag): gains are taxed fully at 30%

The 3:12 rules are complex — most business owners should consult a tax advisor to optimize the salary base and dividend/capital gains strategy.

Lottery Bonds — Premieobligationer

Lottery bonds (premieobligationer) have a unique rule: gains on bonds held for less than 1 year are taxed at 27%, while gains on bonds held for more than 1 year are taxed at the standard 30%. Losses on lottery bonds are 70% deductible regardless of holding period.

Loss Carry Forward

Capital losses that cannot be used in the current tax year can be carried forward indefinitely. However, capital losses may only offset future capital gains and capital income — they cannot offset earned income. The annual 70% deduction limit on share/crypto losses applies each year: if you have a capital loss of SEK 100,000, only SEK 70,000 is deductible that year. Unused losses accumulate and can be applied against future gains.

Exit Tax — Utflyttningsbeskattning

Sweden imposes an exit tax (utflyttningsbeskattning) on individuals who cease Swedish tax residency and hold certain assets. The tax applies to unrealized capital gains on shares in Swedish companies (especially qualified shares in fåmansföretag), Swedish real estate, and business assets. The exit tax is calculated as if the assets were sold at market value on the date of emigration. Payment can be deferred under certain conditions, but interest accrues. The rule aligns with the EU ATAD (Anti-Tax Avoidance Directive) requirements transposed into Swedish law.

Tax Return — K4 Blankett

All capital gains and losses must be reported on the K4 form (blankett K4), which covers shares, funds, other securities, and crypto. Banks and brokers provide pre-filled K4 data for Swedish accounts, which you import into the digital tax return. For crypto and foreign accounts, you must complete the K4 manually. The K4 is filed as part of the Inkomstdeklaration 1 (for individuals) or Inkomstdeklaration 2 (for companies). The deadline is typically early May.

FAQs

Do I pay capital gains tax on my primary residence?

Yes, but only 22/30 of the gain is taxable at 30%, giving an effective rate of 22%. You may also be eligible for a deferral (uppskov) if you buy a more expensive replacement home.

Can I use the 20% simplified method for crypto?

Yes, the schablonmetoden (20% of proceeds as acquisition cost) is available for all listed assets, including crypto. However, it often results in higher tax than the actual cost for assets with significant gains, so use it only if your original cost basis was very low or you lack records.

What is the penalty for not reporting crypto gains?

Failure to report crypto gains can result in a tax surcharge (skattetillägg) of 40% of the unpaid tax. Skatteverket actively requests data from crypto exchanges and can audit transaction histories. Voluntary correction before an audit reduces the penalty to 10%.

Are gifts of shares taxed?

Gifting shares at market value triggers no capital gains tax for the giver (no gain is realized unless sold). The recipient inherits the giver's cost basis. However, if shares are gifted at below market value, the giver may be deemed to have realized a gain at market value. See the inheritance and gift tax guide for details.

Is there any difference between stock exchanges for CGT?

No, the 30% rate applies to all shares listed on any exchange (Stockholm, Nasdaq OMX, foreign exchanges). Foreign exchange fees and currency conversion differences must be accounted for in SEK.
