The data in this calculator is updated regularly to reflect the latest official rates. When in doubt, consult the official sources listed above.
Disposals — selling, swapping between cryptoassets, spending crypto or gifting (except to a spouse) — trigger Capital Gains Tax. Mining, staking rewards and most airdrops are taxed as income when received.
18% within your unused basic-rate band and 24% above (2025/26), after the £3,000 annual exemption. Your salary and other income fill the band first.
No CGT is due and the excess loss carries forward indefinitely against future gains — provided you report it to HMRC within 4 years of the tax year end.
