Key UK Crypto Tax Rules
Same-Day Rule
If you sell crypto and buy the same crypto back on the same day, HMRC matches those shares first for cost-basis purposes. This stops you from manipulating your gains within a single day.
Bed and Breakfasting Rule (30-Day Rule)
If you sell crypto and buy the same crypto back within 30 days, HMRC treats it as if the sale didn’t happen. This prevents “washing” — selling a losing position to realise a loss, then buying it straight back to keep the position.
Section 104 Pool
All holdings of the same crypto are pooled together into a single “Section 104 pool” for cost-basis calculation. This means you can’t pick which coins you’re selling.
Allowable Costs
You can deduct:
- Purchase price
- Transaction fees (exchange fees, network fees)
- Mining equipment costs (if mining as a business)
Record-Keeping Requirements
HMRC requires:
- Date of each transaction
- Value in GBP at time of transaction
- Purpose of the transaction
- Counterparty details (exchange, wallet)
- Evidence of cost basis
How to File
- Self-assessment tax return — Must be filed if crypto gains exceed £3,000 or total crypto disposals exceed £50,000
- Use crypto tax software — Koinly, CoinTracker, Recap all support UK rules
- Report in the “Capital Gains” section — Crypto goes under “Other property, assets and gains”
- Deadline — January 31 following the tax year (April 6 - April 5)
Verdict
The UK has one of the most clearly defined crypto tax regimes in the world. The annual £3,000 CGT exemption means small investors may pay no tax. Higher earners pay 10-20% on gains. Use crypto tax software to calculate your gains accurately.

Key points at a glance
HMRC treats crypto as property, meaning every disposal — including crypto-to-crypto trades and spending on goods — is a CGT event. The £3,000 annual exempt amount means small investors may owe nothing, but gains above this are taxed at 10% or 20% depending on your income band. The same-day rule, 30-day bed-and-breakfasting rule, and Section 104 pool structure determine how HMRC calculates your cost basis. Mining, staking, and certain airdrops are income tax events at receipt, not CGT events. The UK has the most detailed crypto tax guidance of any major economy, and HMRC actively cross-references exchange data.
Tax filing steps for UK crypto users
Gather your transaction records from every exchange, wallet, and DeFi protocol you have used. Apply the same-day rule first, then the 30-day rule if you repurchased within a month, then the Section 104 pool for everything else. Your crypto gains go in the Capital Gains section of the self-assessment return under “Other property, assets and gains.” Report mining or staking income separately under income tax. The filing deadline is 31 January following the end of the tax year (which runs 6 April to 5 April). You must file if crypto gains exceed £3,000 or total disposals exceed £50,000. Use crypto tax software such as Koinly, Recap, or CoinTracker that supports UK-specific rules including the Section 104 pool.
Common errors UK crypto holders make
Forgetting that crypto-to-crypto trades are disposals is the single most common mistake — swapping Bitcoin for an altcoin triggers CGT just like selling for pounds. Another frequent error is not accounting for the 30-day bed-and-breakfasting rule, which means selling at a loss and rebuying within a month does not crystallise the loss. Some holders also miscalculate their Section 104 pool by mixing in FIFO thinking, which produces incorrect gains. HMRC has historically increased its data requests to exchanges and uses blockchain analytics to cross-reference declarations. The penalties for failing to report range from late-filing surcharges to investigations, so accuracy and completeness are essential.
Common questions about UK crypto tax
The £3,000 annual CGT exempt amount applies to total capital gains, not just crypto — so if you also have share disposals, both count toward the same £3,000. The same-day rule matches shares bought and sold on the same day before the Section 104 pool is touched. If you gift crypto to your spouse, it is a tax-free transfer, but gifting to anyone else may trigger CGT and potentially income tax if HMRC treats it as trading. Staking rewards are income tax at receipt at your marginal rate (0%, 20%, 40%, or 45%), and the later disposal of those staked tokens is a separate CGT event. HMRC guidance is published in the Cryptoassets Manual and is periodically updated.
Staying compliant in the UK system
HMRC’s crypto guidance is among the most detailed in the world, and the authority actively cross-references exchange data with self-assessment returns. The £3,000 annual exemption is generous for small holders, but it does not eliminate the reporting obligation if your total disposals exceed £50,000. Treat record-keeping as a habit: log every transaction date, GBP value, purpose, counterparty, and fees. Using a crypto tax tool that generates UK-compliant reports reduces the risk of errors, particularly if you use multiple exchanges or interact with DeFi protocols. The tax year end on 5 April provides a natural annual checkpoint to review your positions and estimate your tax liability.
