In short: selling, swapping or spending crypto is a disposal for Capital Gains Tax. Staking, mining and airdrops are usually income. Costs are worked out using pooling and matching rules.
An investor with £35,000 salary sells crypto for £30,000 that cost £18,000. The gain is £12,000. After the £3,000 exemption, £9,000 is taxed at 18%, so CGT is £1,620.
Under the Cryptoasset Reporting Framework, UK exchanges collect user data from 2026. Our crypto tax returns service handles pooling and matching, and our Capital Gains Tax team advises on planning. More on our tax calculators page.
