Cryptocurrency adoption continues to expand across the United Kingdom, bringing increased attention to tax responsibilities. Her Majesty’s Revenue and Customs (HMRC) classifies cryptoassets as property or investments rather than currency. This means individuals engaging in buying, selling, or earning crypto may be subject to Capital Gains Tax (CGT) or Income Tax. Proper reporting is essential to avoid penalties, making it vital to understand these obligations.
This guide outlines the key principles of UK cryptocurrency taxation according to HMRC’s latest 2025 guidelines. It covers essentials such as capital gains from trading, Income Tax on staking and airdrops, and special cases including NFTs, DeFi activities, and gifting. Practical examples and clear explanations are provided to simplify tax calculations.
Understanding Cryptocurrency Taxation in the UK
Is Crypto Taxable in the UK?
Yes, nearly all cryptocurrency transactions may be considered taxable events. HMRC treats crypto similarly to stocks or property. The two primary taxes that apply are:
- Capital Gains Tax (CGT): Triggered when you dispose of crypto held as an investment.
- Income Tax: Applied when you receive crypto as a form of earnings.
What Counts as a Taxable Event?
A disposal occurs when you:
- Sell crypto for fiat currency (e.g., GBP).
- Exchange one cryptocurrency for another.
- Use crypto to pay for goods or services.
- Gift crypto to someone other than a spouse or civil partner.
Donations to registered charities are generally exempt from CGT.
When Is Income Tax Applied?
You may owe Income Tax if you receive cryptocurrency through:
- Employment or freelance payment.
- Mining or staking activities.
- Earning interest via lending or yield farming.
- Airdrops received in exchange for performing tasks.
Non-Taxable Events
Buying cryptocurrency with fiat or transferring crypto between wallets you own are not taxable. Tax is only due upon disposal or receipt of income.
Tax Rates and Allowances
- CGT Allowance: £3,000 for the 2024–25 tax year. Gains above this are taxable.
- CGT Rates: 18% for basic-rate and 24% for higher-rate taxpayers (from late 2024).
- Income Tax: Personal allowance is £12,570. Rates are 20% (basic), 40% (higher), or 45% (additional rate).
In short, profits from disposals are subject to CGT, while crypto earnings are subject to Income Tax at the point of receipt.
Capital Gains Tax on Cryptocurrency
CGT applies when you dispose of cryptocurrency held as an investment. Calculating gains or losses accurately is essential for compliance.
Triggers for CGT
You must report a disposal when you:
- Sell crypto for fiat.
- Trade one crypto for another.
- Spend crypto on purchases.
- Gift crypto (except to a spouse).
Transfers between your own wallets are not taxable. Gifts to a spouse or civil partner are considered no-gain/no-loss transactions.
Example: If Alice trades 1 ETH (bought for £800) for Bitcoin when ETH is valued at £1,500, she realizes a gain of £700.
Calculating Your Capital Gain
Follow these steps:
- Convert transaction values to GBP using market rates at the time of disposal.
- Determine your cost basis, including purchase price and fees.
- Subtract costs from proceeds to calculate gain or loss.
- Apply your annual allowance and any capital losses.
If you’ve already paid Income Tax on crypto (e.g., from staking), use that taxed value as your cost basis to prevent double taxation.
Pooling and Cost Basis Rules
HMRC requires identical cryptoassets to be pooled. This means:
- Purchases of the same token are merged into a single pool.
- The average cost per unit is used to calculate gains.
- Special rules apply for same-day and 30-day repurchases.
Example: John buys 2 BTC for £30,000. He sells 0.5 BTC for £9,000. His cost basis is £7,500 (half of £30,000), resulting in a £1,500 gain. Since this is below his £3,000 allowance, no tax is due.
Losses must be reported to HMRC to be carried forward.
Reporting and Deadlines
- The tax year runs from 6 April to 5 April.
- You must report if gains exceed the allowance or if disposal proceeds exceed £50,000.
- File online via Self Assessment by 31 January following the tax year.

Income Tax on Cryptocurrency
Income Tax applies to crypto received as earnings or rewards.
Common Income Scenarios
- Salary or freelance pay in crypto.
- Mining and staking rewards.
- Airdrops or bounty payments.
- DeFi yield or lending interest.
- Referral bonuses.
Note: Profits from frequent trading are generally subject to CGT unless you are a professional trader.
Calculating Crypto Income
- Value the crypto in GBP at the time of receipt.
- Add this to your total income for the year.
- Apply the miscellaneous income allowance of £1,000 if applicable.
- Deduct allowable expenses if you are trading as a business.
Example: Bob earns £1,800 from mining and has £200 from other sources. After applying the £1,000 allowance, he pays Income Tax on £1,000.
Crypto received as employment income establishes a cost basis for future CGT calculations.
Tax Treatment of Specific Crypto Activities
Mining and Staking
- Rewards are taxable as miscellaneous income when received.
- If conducted as a business, treat as trading income and deduct expenses.
- No tax is due if rewards are under the £1,000 allowance.
Airdrops and Hard Forks
- Unsolicited airdrops are not subject to Income Tax but may trigger CGT upon disposal.
- Airdrops received for work are taxable as income.
- Hard forks require splitting the original cost basis between the old and new assets.
Non-Fungible Tokens (NFTs)
- Collectors pay CGT on disposal gains.
- Creators pay Income Tax on sales profits and royalties.
- Each NFT must be tracked individually for cost basis.
Decentralized Finance (DeFi)
- Depositing or withdrawing from liquidity pools can trigger CGT.
- Yield rewards are subject to Income Tax.
- Complex transactions may require professional assessment.
Lost or Stolen Crypto
- Losses are not automatically deductible.
- You may claim a negligible value loss to realize a capital loss.
Gifting and Inheritance
- Gifts to spouses are tax-free.
- Gifts to others are disposals at market value.
- Inheritance receives a stepped-up cost basis and may be subject to Inheritance Tax.
