Have you sold shares, cryptocurrency, real estate or another investment in Sweden?
The Finorum Sweden Capital Gains Tax Calculator estimates the tax that may apply under Sweden’s 2026 rules. Enter the acquisition value, sale value and eligible expenses to calculate the estimated capital gain and tax.
Sweden generally taxes private investment income at 30%. However, the effective treatment depends on the asset and the type of account used. Ordinary brokerage accounts, Investment Savings Accounts, cryptocurrency and residential property are not taxed in the same way.

How to Use the Calculator
To obtain an estimate:
- Select Sweden as the country.
- Choose the type of asset sold.
- Enter the acquisition and disposal values.
- Add eligible purchase and selling costs.
- Include compatible gains or losses where relevant.
- Select the correct account or tax route.
- Review the taxable gain and estimated tax.
The standard calculation assumes that the user is an individual Swedish tax resident and that the asset belongs to their private portfolio. Business activity, closely held companies and non-resident taxation may require a different calculation.
General Capital Income Tax Rate
Sweden normally taxes a surplus in the capital-income category at a flat rate of 30%.
This category can include:
- capital gains from securities;
- cryptocurrency gains;
- interest income;
- dividends;
- certain investment-account standard income;
- taxable portions of property gains;
- other qualifying investment income.
Although the general capital-income rate is 30%, not every gain is included in the taxable base in full. For example, only 22/30 of the gain from a qualifying private residence is taxable, producing an effective rate of 22%.
The result can also be affected by deductible capital expenses and losses.
Selling Shares Through an Ordinary Brokerage Account
Profits from selling listed shares through a conventional securities account, known as an aktie- och fondkonto or depå, are generally taxed at 30%.
The basic calculation is:
Capital gain = Sale proceeds − Acquisition cost − Eligible expenses
The acquisition cost usually includes:
- the amount paid for the shares;
- purchase commissions;
- directly related transaction expenses;
- adjustments resulting from certain corporate actions.
Selling expenses such as broker commission reduce the disposal value.
Sweden normally uses an average-cost method for identical shares of the same class rather than matching every sale to one particular purchase. The average acquisition cost must be recalculated when additional shares are purchased or relevant corporate actions occur.
The Swedish Tax Agency confirms that profits on listed shares and other qualifying securities are generally taxed at 30%. Skatteverket
The Standard 20% Cost-Basis Method
For certain listed shares and other listed equity rights, an investor may use a standard method instead of the actual acquisition cost.
Under this method, the acquisition cost is treated as 20% of the net sale proceeds. This effectively makes 80% of the proceeds taxable at 30%.
For example:
- Net sale proceeds: SEK 100,000
- Standard acquisition cost: SEK 20,000
- Taxable gain: SEK 80,000
- Estimated tax: SEK 24,000
The standard method may be helpful where the investor cannot establish the original purchase price or where the actual acquisition cost was exceptionally low.
It should not be used automatically. If the documented acquisition cost exceeds 20% of the net proceeds, the actual-cost method will normally produce a lower taxable gain.
Different rules may apply to fund units, unlisted shares and other instruments.
Losses on Listed Shares
Losses on listed shares and similar listed equity instruments can generally be offset in full against taxable gains on compatible listed securities during the same year.
If a loss remains after this offset, 70% of the remaining amount is generally deductible within the capital-income calculation.
Where the total capital calculation results in a deficit, the taxpayer may receive a tax reduction rather than a refund of the full loss:
- 30% of the capital deficit up to SEK 100,000;
- 21% of the portion exceeding SEK 100,000.
The precise result depends on the taxpayer’s other capital income and expenses.
Losses from unlisted shares, closely held companies and some specialist instruments can be subject to separate limitations.
Investment Savings Account – ISK
An Investeringssparkonto, commonly called an ISK, is not taxed by calculating the actual gain on every sale.
Instead, the taxpayer is charged on standard income calculated from the account’s capital base. Sales, exchanges, dividends and reinvestments within the ISK do not normally produce separately declared capital gains.
For income year 2026:
- the standard-income rate is 3.55% of the capital base;
- the resulting standard income is taxed at 30%;
- the effective ISK tax is therefore 1.065% of the taxable capital base;
- a tax-free base of SEK 300,000 applies to combined qualifying savings.
The SEK 300,000 allowance covers the taxpayer’s combined eligible savings in ISK accounts, Swedish endowment insurance and qualifying PEPP products. It is not a separate SEK 300,000 allowance for each account.
For example, if the relevant capital base above the allowance is SEK 500,000:
- standard income: SEK 500,000 × 3.55% = SEK 17,750
- estimated tax: SEK 17,750 × 30% = SEK 5,325
The deduction for the tax-free base is generally applied automatically.
Skatteverket confirms that the 2026 effective ISK tax is 1.065% on the relevant capital base above the SEK 300,000 tax-free threshold. Skatteverket
Why the Account Type Matters
A gain from a share sale may produce very different tax results depending on where the investment is held.
In an ordinary brokerage account:
- the actual realised gain is normally taxed at 30%;
- losses may be deductible under the capital-loss rules;
- sales must generally be reported.
In an ISK:
- the actual gain from an individual sale is not taxed separately;
- the account is taxed annually using its capital base;
- losses inside the account are not separately deductible;
- tax can arise even when the portfolio falls in value.
The calculator must therefore use the correct account route. Applying the ordinary 30% capital gains calculation to an ISK sale would produce a misleading result.
Endowment Insurance
A Swedish kapitalförsäkring, or endowment insurance, is also generally taxed on a standardised basis rather than according to each realised gain.
The insurance provider normally handles the Swedish yield-tax calculation. The policyholder does not usually declare each sale made within the policy.
The 2026 tax-free savings base is shared across eligible ISK accounts, endowment-insurance products and PEPP savings.
Foreign insurance policies can involve different reporting and tax obligations and should not automatically be treated like a Swedish kapitalförsäkring.
Cryptocurrency Taxation in Sweden
A private individual generally realises a taxable event when cryptocurrency is:
- sold for Swedish kronor or another fiat currency;
- exchanged for another cryptocurrency;
- used to purchase goods or services;
- lent out in a transaction that transfers ownership;
- otherwise disposed of for consideration.
A crypto-to-crypto exchange is taxable even where no cash is received.
The gain is generally calculated as:
Capital gain = Disposal value − Average acquisition cost − Eligible expenses
Profits are taxed at 30%.
A cryptocurrency loss is generally deductible at 70%, rather than being fully deductible. Skatteverket explicitly confirms the 30% tax on gains and the 70% deductibility of losses. Skatteverket
Example of a Cryptocurrency Sale
Suppose an investor:
- buys cryptocurrency for SEK 100,000;
- sells it for SEK 160,000;
- pays SEK 2,000 in eligible transaction fees.
The estimated gain is:
SEK 160,000 − SEK 100,000 − SEK 2,000 = SEK 58,000
At the 30% capital-income rate, the estimated tax would be:
SEK 58,000 × 30% = SEK 17,400
If the transaction instead generated a SEK 58,000 loss, only 70% would generally be deductible:
SEK 58,000 × 70% = SEK 40,600 deductible amount
The final tax effect would depend on the taxpayer’s other capital income and expenses.
Cryptocurrency Records
Crypto investors should retain:
- exchange transaction histories;
- wallet addresses;
- purchase and sale confirmations;
- Swedish-krona market values for every disposal;
- network and trading fees;
- records of crypto-to-crypto exchanges;
- documentation of transfers between personal wallets;
- evidence relating to staking, mining or lending income.
Transfers between wallets owned by the same person do not normally constitute disposals. Records remain important to demonstrate that beneficial ownership did not change.
Mining, staking rewards, interest-like returns and extensive professional activity may be classified differently from the disposal of a privately held cryptoasset.
Selling a Private Residential Property
A profit from selling a qualifying private residential property is effectively taxed at 22%.
This is achieved by including 22/30 of the profit in the capital-income category and taxing that amount at 30%:
30% × 22/30 = 22% effective tax
For example, a profit of SEK 500,000 would result in:
- taxable portion: SEK 500,000 × 22/30 = approximately SEK 366,667
- estimated tax: approximately SEK 110,000
Skatteverket confirms that 22/30 of the gain from a private residential property is taxable, producing an effective 22% rate. Skatteverket
Calculating the Property Gain
The basic calculation is:
Sale price − Selling expenses − Purchase price − Eligible improvement costs = Profit or loss
Eligible selling expenses can include:
- estate-agent fees;
- certain survey expenses;
- qualifying homestyling expenses;
- legal costs directly connected with the sale.
Eligible acquisition costs can include the purchase price and certain expenses connected with acquiring the property, such as registration of ownership and mortgage-deed costs.
Improvement expenses can include:
- new construction;
- extensions;
- reconstruction;
- qualifying repairs and maintenance.
Improvement costs generally need to total at least SEK 5,000 during the relevant year.
For ordinary repairs and maintenance, only work performed during the year of sale or the previous five years is normally considered, and the property must be in better condition at sale than it was when acquired. New construction, extensions and reconstruction are not subject to the same five-year restriction.
Loss on a Private Residence
When a qualifying private residence is sold at a loss, 50% of the loss is generally deductible in the capital-income calculation.
For example:
- Actual property loss: SEK 200,000
- Deductible portion: SEK 100,000
The final tax reduction depends on the taxpayer’s overall capital surplus or deficit.
A commercial or investment property is treated differently. For such property, 90% of a gain may be taxable at 30%, producing an effective rate of 27%, while 63% of a loss may be deductible.
The correct property classification is therefore essential.
Deferring Tax on a Home Sale
A taxpayer who sells a permanent residence at a profit and purchases a qualifying replacement residence may be entitled to defer taxation of all or part of the gain.
The sold and replacement homes must generally be located in Sweden or another country within the European Economic Area.
Additional conditions apply to:
- the period during which the seller lived in the former home;
- when the replacement home is purchased;
- when the taxpayer moves into it;
- the price of the replacement property;
- the minimum amount of the deferral.
For a home sold in 2026, the replacement residence can generally be purchased between 1 January 2025 and 31 December 2027, with the move completed by 2 May 2028.
The deferral must generally amount to at least SEK 50,000. The maximum deferral is generally SEK 3 million for a taxpayer who owned the entire property, with a proportionate limit for partial ownership.
A less expensive replacement property may limit the amount that can be deferred.
Skatteverket provides the applicable replacement-home dates and the principal deferral requirements. Skatteverket
No General Home-Sale Exemption Based on Age
Unlike certain EU countries, Sweden does not generally exempt the gain from a private home simply because the seller has reached a particular age.
The effective 22% property-gain tax normally applies unless the taxpayer qualifies for a deferral or another specific rule.
A deferred gain is not permanently exempt. It is normally brought back into taxation when the replacement residence is sold, unless a new qualifying deferral is available.
Reporting the Sale
Swedish tax residents generally report capital gains and losses through the annual Inkomstdeklaration 1.
Common forms include:
- K4 for listed shares, securities and cryptocurrency;
- K5 for a qualifying house, terraced house, holiday home or owner-occupied apartment;
- K6 for a tenant-owner apartment or tenant-owner house;
- K7 for commercial property;
- K12 for certain unlisted shares.
A sale is normally reported in the year following the year in which the binding sale agreement was signed.
For example, an asset sold under a binding agreement during 2026 would generally be included in the tax return filed in 2027.
Foreign Assets and the Ten-Year Rule
Swedish tax residents are generally liable for Swedish tax on relevant worldwide investment gains, including sales of foreign shares, cryptocurrency and overseas property.
Tax treaties and foreign tax credits can affect the final liability where another country also taxes the same gain.
People who have moved away from Sweden may remain subject to Swedish tax on certain share disposals under Sweden’s ten-year rule. Tax treaty provisions can limit Sweden’s right to tax in individual cases.
The standard calculator assumes full Swedish tax residence and does not automatically apply treaty relief.
Calculation Assumptions
Unless otherwise selected, the calculator assumes that the user:
- is an individual Swedish tax resident;
- owns the asset privately;
- has selected the correct account type;
- is not conducting a professional trading business;
- can document the acquisition value and eligible costs;
- uses Swedish kronor for the tax calculation;
- applies the rules relevant to disposals made in 2026.
Special rules can apply to closely held companies, employee shares, inherited assets, gifts, corporate reorganisations, derivatives, business property and foreign insurance products.
Important Notice
The Finorum Sweden Capital Gains Tax Calculator provides an estimate for informational purposes only. The final result depends on the asset type, investment account, total capital income, available losses, property classification, foreign-tax position and supporting documentation.
An ISK or endowment-insurance account should not be calculated as an ordinary securities account. Likewise, a private residence, commercial property and cryptocurrency each require a different tax route.
Before completing a significant transaction or submitting an official return, consult a qualified Swedish tax adviser or Skatteverket.
