How Crypto Gains Are Taxed in the United Kingdom
For informational purposes only. This guide does not constitute tax, legal, or investment advice. Tax treatment depends on individual circumstances. Consult a licensed professional for advice specific to your situation.
Overview
HMRC does not treat cryptocurrency as currency. Instead, digital assets are classified as a capital asset — meaning disposals are subject to Capital Gains Tax (CGT), and income events (such as staking rewards and mining proceeds) are subject to Income Tax. Understanding which category applies to each transaction is the foundation of compliant crypto reporting.
What counts as a disposal?
A disposal occurs whenever you sell crypto for fiat, exchange one cryptocurrency for another, use crypto to purchase goods or services, or gift crypto to anyone other than a spouse or civil partner. Each disposal is a separate CGT event, and you must calculate the gain or loss for each one individually.
The Section 104 pool rule
HMRC applies a pooling rule (the Section 104 pool) to crypto assets of the same type. Rather than tracking the cost of individual coins, you maintain a running average cost across all acquisitions of that coin. This means the order in which you acquired coins does not affect your gain calculation — except where the 30-day same-day and bed-and-breakfast rules apply.
Staking and yield income
Rewards received from staking, yield farming, and liquidity mining are generally treated as miscellaneous income at the time of receipt, with the market value on that date forming the Income Tax charge. When you subsequently dispose of those tokens, CGT applies on any further gain above that income value. This creates a layered tax position that requires careful record-keeping.
Reporting obligations
If your total crypto gains exceed the annual CGT exemption (£3,000 for 2024/25), or if total proceeds exceed four times the exemption threshold, you are required to report via Self Assessment. HMRC has significantly increased enforcement activity in this area, including data-sharing arrangements with major exchanges operating in the UK.
What you should do now
Begin by aggregating transaction records across all exchanges and wallets you have used. Specialist software can assist with this, though manual reconciliation is sometimes necessary for DeFi activity. If your portfolio is of meaningful scale, engaging a specialist adviser before year-end allows time for strategic disposals that may reduce your CGT liability.
