Understanding Your Capital Gains Tax
Capital Gains Tax (CGT) is a tax on the profit you make when you sell an asset. The amount of tax you pay depends on the type of asset, the size of the gain, and your personal income tax band. The 2026/27 tax year has an annual exempt amount of £3,000, meaning you can realise gains up to this amount tax-free.
Your income level determines the rate you pay. If your total income, including the taxable gain, falls within the basic rate tax band (£12,571 to £50,270 for 2026/27), you pay the lower CGT rate. Any portion of the gain that pushes your total income into the higher rate band is taxed at the higher CGT rate. For help with income tax, see our Income Tax Calculator.
Different assets have different rates. Residential property gains are taxed at 18% (basic rate) and 24% (higher rate), while other assets like shares, business assets, or valuable antiques are taxed at 10% (basic rate) and 20% (higher rate).
