UK Capital Gains Tax Rates 2025/26
CGT is charged on the profit when you sell an asset that has increased in value. The annual exemption is £3,000 — gains below this are tax-free.
Shares and other assets: 10% (basic rate) / 20% (higher rate). Residential property: 18% (basic rate) / 24% (higher rate). Your CGT rate depends on your total taxable income — if the gain pushes you into the higher rate band, the excess is taxed at the higher rate.
