Capital Gains Tax rates for cryptoassets

Capital Gains Tax is charged on the gain you make when you dispose of cryptoassets, not on the amount you sell them for.

Annual exempt amount

You only pay Capital Gains Tax on gains above the annual exempt amount. For the 2025 to 2026 tax year this is £3,000.

Rates

If your gain pushes you into a higher band, part of the gain may be taxed at each rate.
