Cryptocurrencies have surged in popularity across the UK, bringing with them significant tax obligations. Her Majesty’s Revenue & Customs (HMRC) classifies cryptoassets as property or investments rather than currency. Consequently, UK residents engaging in cryptocurrency transactions—whether buying, selling, or earning—may face Capital Gains Tax (CGT) or Income Tax. Non-compliance can result in penalties, making it essential to understand these requirements.
This guide outlines the UK’s cryptocurrency tax framework under HMRC’s 2025 rules, covering:
- CGT on trading and disposals
- Income Tax on staking, mining, and airdrops
- Special cases (NFTs, DeFi, lost assets, gifts)

Crypto Tax Fundamentals
Is Crypto Taxable in the UK?
Yes. HMRC treats crypto similarly to stocks or property, triggering tax in two scenarios:
Capital Gains Tax (CGT)
- Applied when disposing of crypto held as an investment (e.g., selling, trading, spending).
Income Tax
- Levied on crypto received as payment (e.g., salary, mining rewards, DeFi yield).
Taxable Events
- Selling crypto for fiat (e.g., BTC to GBP).
- Swapping one crypto for another.
- Using crypto for purchases.
- Gifting crypto (excludes spouse/civil partner).
Non-taxable: Buying crypto with fiat or transferring between personal wallets.
Tax Rates & Allowances (2025)
| Tax Type | Allowance | Rates |
|------------------------|----------------|-------------------------------|
| Capital Gains Tax | £3,000 | 18% (basic), 24% (higher) |
| Income Tax | £12,570 | 20%–45% (based on income) |
Capital Gains Tax (CGT) on Crypto
Calculating Gains
- Convert to GBP: Use market value at disposal.
- Determine Cost Basis: Purchase price + fees (pooling applies).
- Compute Gain/Loss: Proceeds − Cost − Allowable Expenses.
Example: Alice trades 1 ETH (bought for £800) for 0.05 BTC when ETH = £1,500. Her gain: £1,500 − £800 = £700.
Pooling Rules
- Identical assets are pooled (average cost basis).
- Same-day/30-day rules apply for matching sales.
Reporting: Required if gains exceed £3,000 or proceeds exceed £50,000. Deadline: 31 January following the tax year.
Income Tax on Crypto
Taxable Income Scenarios
- Mining/staking rewards.
- Crypto salaries/freelance payments.
- DeFi yield or lending interest.
Calculation: Value at receipt added to taxable income.
Example: Bob mines £1,800 in crypto. After £1,000 miscellaneous allowance, £800 is taxable.
