After the £3,000 annual exempt amount, a basic-rate taxpayer (£35,000 other income) owes £6,318 CGT on a £30,000 gain. A higher-rate taxpayer (£55,000 other income) owes £6,480.
The annual exempt amount for 2026/27 is £3,000. After deducting this, the taxable gain is £27,000.0. Gains within your remaining basic-rate band are charged at 18%. Gains above the basic-rate band are charged at 24%.
Your other taxable income (salary, self-employment, etc.) fills the basic-rate band first. A basic-rate taxpayer on £35,000 has £15,270 of basic-rate band remaining — so smaller gains may fall entirely within the 18% band. A higher-rate taxpayer on £55,000 has already exceeded the £50,270 limit, so gains are charged at 24%.
