Capital gains tax in Sweden Confirm the cited source.

Sweden does not have a standalone capital gains tax separate from its broader income-tax system. Instead, capital gains are assessed within the inkomst av kapital (income from capital) category, which is taxed at a flat national rate of 30%. The framework applies to the net result of the category for the full income year, so losses in one area can reduce gains in another, subject to the rules described below.

For most individual investors the practical rate depends heavily on the type of asset sold and whether the investment is held inside a tax-efficient account wrapper.

01How are listed shares and investment funds taxed?

Gains from selling listed shares, equity funds, bond funds, and other traded securities held outside a tax-efficient wrapper are taxed at the full 30% rate. The cost basis is calculated using the genomsnittsmetoden (average-cost method): all units of the same security are treated as a single pool, and the per-unit cost is the total purchase cost divided by the total number of units held. There is no lot-selection flexibility. An alternative called the schablonmetoden allows the seller to substitute 20% of the sale proceeds as a deemed cost basis for listed shares only, producing an effective rate of 24% on proceeds; this is useful when actual purchase records are unavailable or the holding is very long-dated. Capital losses on shares and funds are 70% deductible against other capital income for the year, and any remaining net loss in the capital category generates a 30% tax reduction against other income taxes (capped at the tax attributable to the capital deficit). Gains and losses must be reported annually on Form K4 (fondandelar and vaaerdepapper sections) attached to the personal income tax return.

02What is the capital gains rate on a private home or bostadsratt?

The gain from selling a privatbostad (owner-occupied house) or a bostadsratt (tenant-owned cooperative apartment used as a primary residence) is taxed at an effective 22%. This is not a separate rate: Swedish tax law includes only 22/30 of the gain in the taxable base, and the standard 30% rate then applies to that reduced base (30% x 22/30 = 22%). A standard deduction of SEK 40,000 is available per property before the gain is computed. Repair and improvement costs incurred in the year of sale or the preceding five years, and capital improvements at any time during ownership, are deductible from the gain, provided each annual total exceeds SEK 5,000. Losses on private residences are only 50% deductible. The sale must be reported on Form K5 (house) or Form K6 (bostadsratt).

The uppskov (tax deferral) mechanism under Chapter 47 of the Income Tax Act (Inkomstskattelagen, IL) allows a seller to defer the 22% tax if a qualifying replacement residence is purchased within the EEA. Key conditions: the sold property must have served as the seller's main home for at least one year; the deferral cannot apply to holiday homes; and the deferred gain cannot exceed SEK 3,000,000 per person (SEK 6,000,000 for couples who jointly owned the property). The deferred gain sits as an ongoing entry in the tax return and becomes taxable when the replacement home is eventually sold without a further reinvestment. There is no annual interest charge on the deferred amount -- a charge that previously applied at 0.5% per year was abolished from 1 January 2021, making indefinite deferral via successive replacement purchases substantially more attractive than it was before.

03How do ISK and kapitalforsakring accounts affect capital gains?

The ISK (investeringssparkonto, investment savings account) and the kapitalforsakring (endowment insurance wrapper) replace capital gains tax and dividend tax on assets held inside the accounts with a small annual deemed-return charge called the schablonskatt.

The schablonskatt is calculated each year as: schablonintakt percentage x average account value x 30%. The schablonintakt percentage equals the government borrowing rate (statslanerantan) on 30 November of the preceding year, plus one percentage point, subject to a minimum floor. For 2025, the statslanerantan on 30 November 2024 was 1.96%, giving a schablonintakt rate of 2.96% and an effective annual tax of approximately 0.89% of account value. The account value used is the quarterly average: the balance at the start of each quarter plus all deposits made during the year, divided by four. From 2025, a tax-free threshold of SEK 150,000 (rising to SEK 300,000 from 1 January 2026) applies, so accounts below that level owe no schablonskatt at all.

The critical consequence is that there is no separate CGT event inside an ISK or kapitalforsakring when securities are sold: gains and dividends accumulate tax-free within the wrapper. Foreign withholding tax on dividends paid from non-Swedish sources cannot be credited against the schablonskatt, which is a disadvantage compared to direct ownership for portfolios heavy in non-treaty foreign income. Kapitalforsakring additionally allows beneficiary designations and ownership transfers without a disposal event, making it popular for inheritance planning and corporate investment structures where ISK (restricted to individual account holders) is unavailable.

04What are the 3:12 rules for closely held companies?

Owners of famansfoeretag (closely held companies, typically private limited companies where the owner also works actively in the business) face a separate framework called the 3:12 rules (tretoelvsreglerna). These rules govern how dividends and capital gains from the sale of qualifying shares are split between the preferentially taxed capital-income category and the higher-taxed employment-income category.

Each year, an owner calculates a gransbelopp (dividend allowance). Dividends and capital gains up to the gransbelopp are taxed at 20% (a reduced rate within the capital-income category). Distributions above the gransbelopp are reclassified as employment income and taxed at progressive rates that can reach 55%, though without employer social security contributions.

For 2025, the simplified calculation method (schablonregeln) gives a gransbelopp of approximately SEK 209,550 per company (2.75 income base amounts, where the 2024 income base amount is SEK 76,200). More complex main-rule calculations incorporating the owner's wage base and share acquisition cost can yield a higher allowance. Unused allowances carry forward with indexation (note: from 1 January 2026, a major reform removes the indexation on carried-forward amounts and changes how the basic allowance is shared across multiple company holdings -- the 2025 rules described here apply to income year 2025 returns filed in 2026). Capital gains from selling qualifying shares in a famansfoeretag are subject to the same gransbelopp split: gains up to the allowance taxed at 20%, excess gains at employment rates.

05What losses are deductible against capital gains?

Losses on listed shares and funds are 70% deductible against other capital income (interest, dividends, other gains) in the same year. If the capital-income category runs a net loss after all gains and losses are combined, that net loss generates a 30% tax reduction applied against other Swedish taxes (income tax, municipal tax) -- this reduction cannot be refunded in cash but does reduce the current year's total tax bill. The reduction carries no forward to future years: unused reductions are permanently lost. Losses on private residences are only 50% deductible within the capital-income category. ISK and kapitalforsakring accounts have no individual loss events by construction.

Capital-gains positions and losses form part of the annual Inkomstdeklaration 1 (personal income tax return), pre-populated by Skatteverket with data from Swedish financial institutions. Returns are filed by 2 May following the income year (e.g., the 2025 income-year return is due 2 May 2026). Non-residents with Swedish-source capital gains (Swedish-listed shares, Swedish real estate) remain liable for Swedish CGT even without Swedish residency, and must file a special non-resident return.

Individuals with complex positions spanning multiple asset types, corporate wrappers, and cross-border holdings should work with a qualified tax professional familiar with Swedish tax law. TaxPros Rated lists Swedish-qualified practitioners at taxprosrated.com/global/jurisdictions/country/se.
