Crypto Tax Calculator

HMRC treats cryptocurrency as a form of property for tax purposes. Capital Gains Tax applies when you dispose of crypto (sell, swap, spend, or gift). The gain is the difference between disposal proceeds and acquisition cost. Income Tax may apply to crypto received as payment, mining income, staking rewards, or airdrops.

The Capital Gains Tax annual exempt amount for 2025/26 is £3,000 per individual. This was reduced from £6,000 in 2023/24 and £12,300 in 2022/23. The exemption applies to all capital gains combined (crypto, shares, property), not per asset type. Couples can each use their own exemption.

You must report crypto disposals if your total disposal proceeds exceed 4 times the annual exempt amount (£12,000 for 2025/26), or if you have a taxable gain after the exemption. Even if you make a loss, it is worth reporting to carry losses forward. HMRC can request data from UK crypto exchanges.

The share matching rules apply to crypto: if you sell and repurchase the same token within 30 days, you must use the cost of the repurchased tokens (not the original cost) to calculate your gain or loss. This prevents bed-and-breakfasting (selling to crystallise a loss and immediately rebuying).

Yes. Capital losses from crypto disposals can be offset against other capital gains in the same tax year or carried forward to future years. Losses must be reported to HMRC within 4 years of the end of the tax year in which they arose. You cannot offset capital losses against income.

Staking rewards and mining income are generally treated as miscellaneous income and subject to Income Tax. DeFi lending returns may be treated as income or capital depending on the arrangement. Providing liquidity in DeFi pools involves disposal events when tokens are swapped. HMRC guidance on DeFi continues to evolve.
