About the Capital Gains Tax Calculator
The Capital Gains Tax Calculator is free to use and all calculations run entirely in your browser. Capital Gains Tax (CGT) is charged on the profit made when you sell or dispose of an asset that has increased in value. This tool calculates your CGT liability for assets such as shares, investment property, and other chargeable assets across Europe.
How CGT Is Calculated
Capital gains tax is charged on your net gain — the sale proceeds minus the original purchase cost (and allowable costs such as legal fees and improvements). Your net gain is then reduced by the annual CGT exemption. The remaining taxable gain is added to your income to determine which tax band it falls into. Rates and exemptions vary by country.
Assets Subject to Capital Gains Tax
- Shares and investment funds held outside a tax-sheltered account or pension
- Second homes and buy-to-let residential property
- Business assets and goodwill
- Cryptocurrency and digital assets
- Personal possessions above the relevant exemption threshold
Ways to Reduce Your Capital Gains Tax Bill
You can reduce capital gains tax by using your annual allowance each tax year, transferring assets to a spouse or civil partner (who has their own allowance), using losses to offset gains, and sheltering investments in tax-advantaged accounts. Timing the disposal of assets across two tax years can also spread and reduce your liability.
