Crypto Tax in United Kingdom
Tax authority: HMRC · Last updated: 2026
The UK has clear, well-documented crypto tax rules managed by HMRC. Cryptocurrency is generally treated as property — not currency — and disposals are typically subject to Capital Gains Tax. The UK uses a unique Share Pooling method for cost basis, and the annual CGT exemption dropped to £3,000 in 2024/25. HMRC has been actively requesting data from exchanges and sending nudge letters to non-compliant taxpayers.

Common Scenarios
Share Pooling (Section 104)
The UK requires Share Pooling — you cannot use FIFO or LIFO. Your cost basis is the weighted average of all tokens of the same type in your 'pool.' Same-day and 30-day (bed and breakfast) rules override the pool for recent purchases. This makes manual tracking difficult and tax software essential.
Bed and breakfast rule
If you sell crypto and rebuy the same token within 30 days, the sale is matched with the repurchase — not the pooled cost. This prevents wash-sale-like strategies. Unlike the US, a 30-day waiting period applies before rebuying to effectively realize a loss.
DeFi and yield
HMRC's guidance on DeFi is evolving. Lending and staking returns are generally miscellaneous income. Liquidity provision may be treated as a disposal, triggering CGT. Wrapping tokens (e.g., ETH to WETH) is likely a disposal. HMRC's DeFi consultation is ongoing.
Spouse transfers
Transferring crypto to a spouse or civil partner is not a taxable event under HMRC rules. The recipient inherits your cost basis. Some couples use this to take advantage of both partners' CGT annual exemptions or differing tax bands — consult a tax advisor to understand how this applies to your situation.

Frequently Asked Questions
- Does HMRC track crypto?
- Yes. HMRC has requested bulk data from UK-accessible exchanges including Coinbase, Binance, and others. They also participate in international information sharing through the OECD's Crypto-Asset Reporting Framework (CARF). HMRC has sent 'nudge letters' to suspected non-compliant crypto holders.
- What is Share Pooling?
- Share Pooling (Section 104) is a cost basis method that calculates the average cost of all tokens of the same type. When you buy 1 BTC at £20,000 and 1 BTC at £30,000, your pool is 2 BTC with a pooled cost of £50,000 (£25,000 average). Same-day and 30-day matching rules are applied before the pool.
- Can I use my CGT exemption for crypto?
- Yes. The first £3,000 of capital gains in each tax year (2024/25 onwards) are tax-free. This applies to all capital gains combined — not just crypto. If your total gains from crypto, shares, and property are under £3,000, you pay no CGT. You may still need to report if total proceeds exceed 4x the exemption.
- How is mining and staking taxed?
- Mining and staking rewards are treated as miscellaneous income, taxed at your income tax rate when received. You then have a cost basis equal to the income value. When you later sell, any gain above that cost basis is subject to CGT. If mining is a trade (substantial, organized activity), it's taxed as trading income instead.
- Do I need to file a Self Assessment?
- You must file a Self Assessment tax return if your total crypto gains exceed the £3,000 annual exempt amount, or if total disposal proceeds exceed £12,000 (4x the exemption). Capital gains go on the SA108 Capital Gains Summary supplementary pages.
