What this means
Capital Gains Tax is charged on the profit when you sell or dispose of an asset that has risen in value. You get a tax-free annual exempt amount (£3,000 for 2026/27); gains above this are taxed at 18% or 24% depending on your income.
Frequently asked questions
Since 30 October 2024 the main CGT rates are 18% for gains within the basic-rate band and 24% above it, for shares, funds, crypto and residential property alike.
For 2026/27 the annual exempt amount is £3,000. You only pay Capital Gains Tax on total gains above this in the tax year.
Usually no. Private Residence Relief normally means your main home is exempt. CGT typically applies to second homes, buy-to-let property, shares outside an ISA and other investments.
