Crypto in the UK — Tax, Rules and How to Buy

Crypto is legal to buy, hold and sell in the UK. It is not legal tender, it is not covered by the Financial Services Compensation Scheme, and the rules around how it can be marketed to you are among the strictest anywhere.

Who regulates it

The Financial Conduct Authority supervises crypto firms for anti-money-laundering purposes and controls how crypto can be promoted. Two consequences you will notice directly: first-time buyers face a mandatory cooling-off period and risk warnings before they can proceed, and crypto derivatives — futures, options, leveraged products — cannot be sold to UK retail customers at all. If a platform offers you leverage as a UK retail user, that is a warning sign about the platform.

Note what the FCA does not do: it does not vet whether a token is a good investment, and registration is not an endorsement.

How it is taxed

HMRC treats crypto as property. Disposals fall under Capital Gains Tax.

• The annual exempt amount is now small. It has been cut repeatedly and sits at £3,000, down from over £12,000 a few years ago. This is the reason many people who never had to report crypto now do — the gain did not grow, the allowance shrank.
• Crypto-to-crypto is a disposal. Swapping ETH for SOL realises a gain in pounds even though no pounds moved.
• Pooling rules apply. HMRC does not let you pick which coins you sold. Holdings of the same token go into a single pool with an averaged cost, and same-day and 30-day rules override that for recent purchases. This is genuinely fiddly and is where most self-filed returns go wrong.
• Mining, staking and some airdrops can be income rather than capital, taxed at your income tax rate when received, and then subject to CGT on later disposal.

Reporting happens through Self Assessment. If your disposals are large enough you may need to report even when the gain is within your allowance.

Where you can actually buy

The UK has good fiat access. Coinbase and Kraken both support Faster Payments, which means a GBP transfer usually lands within minutes and at no cost from the exchange’s side — a meaningful advantage over card funding, which is expensive everywhere. Bank support for crypto payments varies: several UK banks limit or block transfers to exchanges, and some cap the amount per day, so check your own bank before assuming a transfer will go through.

Compare what a trade actually costs on each venue in our exchange comparison — for a UK buyer using Faster Payments, the trading fee is the whole cost, so the difference between venues is the difference in what you keep.

The mistakes that cost UK investors money

• Funding with a debit card instead of a bank transfer. Faster Payments is free and near-instant; card funding carries a percentage fee on every purchase.
• Assuming small gains are invisible. With a £3,000 allowance and exchanges now reporting data to HMRC under international exchange-of-information rules, unreported disposals are far more visible than they were.
• Trying to reconstruct pooled cost bases at the last minute. Keep a running record from the first purchase; it is close to impossible to rebuild years later from exchange exports alone.
