Is my crypto taxable in the UK?

Yes. HMRC treats crypto as a capital asset, not a currency. This means: selling crypto for cash, swapping one cryptocurrency for another, using crypto to buy goods or services, and gifting crypto (except to a spouse) can all trigger Capital Gains Tax. If your total gains in the year exceed the £3,000 annual exempt amount, you'll owe CGT at 18% or 24% depending on your income. Some crypto activity — like staking rewards, mining income, and certain DeFi transactions — may be treated as income rather than capital gains and taxed differently. HMRC requires you to keep records of every transaction. This falls under our £199 Advanced Tax Return.
