Whether you have traded Bitcoin, earned DeFi yield, received crypto as income, or sold NFTs, you likely have a UK tax liability in 2026. This is the most comprehensive UK crypto tax guide available, covering every major scenario, HMRC rules, Capital Gains Tax rates, and how to stay compliant.

Does HMRC Tax Cryptocurrency in the UK?
Yes. HMRC does not consider cryptocurrency to be currency or money. Instead, it is treated as a capital asset — similar to shares or property. This means most crypto transactions are subject to Capital Gains Tax (CGT) and, in some cases, Income Tax and National Insurance Contributions (NICs).
HMRC first issued crypto tax guidance in 2014 and has significantly expanded it since. In 2026, HMRC has full data-sharing agreements with major UK-accessible exchanges including Coinbase, Kraken and Binance, meaning non-declaration is a serious legal risk. The message is clear: report your crypto gains accurately.
UK Crypto Tax Rules in 2026: Key Rates and Thresholds
Capital Gains Tax (CGT) on Crypto
- Annual CGT allowance (2025/26): £3,000 — gains below this are tax-free
- Basic rate taxpayer CGT rate on crypto: 18%
- Higher/additional rate taxpayer CGT rate on crypto: 24%
- Reporting requirement: If your total gains exceed £3,000 OR total proceeds exceed £50,000, you must report via Self Assessment
Note: CGT rates on crypto aligned with residential property rates following the Autumn 2024 budget. Always check gov.uk or consult a qualified accountant for the latest rates.
Income Tax on Crypto
Crypto received as income is taxed as income, not capital gains. This applies to:
- Mining rewards (if conducted as a business or regularly)
- Staking rewards
- DeFi interest and yield
- Crypto received as employment income or salary
- Referral bonuses and airdrops (in some cases)
Which Crypto Activities Are Taxable in the UK?
The following transactions are taxable events under HMRC rules:
- Selling crypto for fiat (GBP) — CGT applies on the gain
- Swapping one crypto for another — CGT applies as if you sold the first crypto
- Paying for goods or services with crypto — treated as a disposal
- Receiving crypto as payment for work — Income Tax applies
- Mining rewards — Income Tax applies on receipt; CGT on disposal
- Staking rewards — Income Tax applies on receipt
- DeFi yield and liquidity pool income — complex; likely Income Tax on receipt
- NFT sales — CGT applies
- Airdrops — potentially Income Tax if received in return for services
What Is NOT Taxable in UK Crypto
Some transactions do not trigger a tax event:
- Buying crypto with GBP (no gain realised)
- Holding crypto (no disposal = no CGT)
- Transferring crypto between your own wallets
- Gifting crypto to a spouse or civil partner
- Donating crypto to HMRC-registered charities
HMRC Crypto Pooling Rules: The Section 104 Rule
UK crypto tax uses a specific calculation method called the Section 104 pooling rule. This means you cannot simply match specific purchases to specific sales. Instead, HMRC calculates your gain using an average cost basis across your entire holding of each cryptocurrency.
The rules also include a 30-day bed and breakfasting rule: if you sell crypto and buy back the same crypto within 30 days, HMRC matches the sale to the new purchase — not the pool — to prevent artificial tax losses.
DeFi Tax in the UK: The Most Complex Area
Decentralised finance activities sit in a grey area that HMRC has only partially addressed. The general principles are:
- Liquidity provision: Adding crypto to a liquidity pool may constitute a disposal if you receive LP tokens in return
- Yield farming rewards: Treated as income on receipt
- Wrapped tokens: Wrapping ETH to WETH may be a disposal — HMRC has not confirmed definitively
- Loans and collateral: Using crypto as collateral for a DeFi loan is generally not a disposal, but liquidation likely is

How to Calculate Your UK Crypto Tax
Calculating your crypto tax accurately requires:
- Complete transaction history: Export all trades, transfers, income events from every exchange and wallet you have used
- GBP valuation at time of transaction: Use the GBP price at the exact date and time of each transaction
- Apply Section 104 pooling: Calculate the average cost pool for each asset
- Apply 30-day matching rules: Identify any same-day or 30-day re-purchases
- Calculate gain or loss per disposal: Sale proceeds minus allowable cost
- Total all gains and losses across the tax year: HMRC tax year runs 6 April to 5 April

HMRC Crypto Tax Investigations: What to Know

Frequently Asked Questions: UK Crypto Tax 2026
Do I need to pay tax on crypto in the UK if I made a loss?
You do not pay tax on a loss, but you should still report it. Crypto losses can be offset against other capital gains in the same tax year or carried forward to future years. Register losses with HMRC via Self Assessment within 4 years.
Is staking income taxable in the UK?
Yes. HMRC currently treats staking rewards as income, subject to Income Tax at your marginal rate on the GBP value at the time you receive them. A subsequent disposal of the staked tokens is then subject to CGT on any further gain.
Do I pay UK crypto tax if I live abroad?
UK tax residency rules are complex. Generally, if you are UK resident for tax purposes, you pay UK tax on your worldwide income and gains — including crypto. Non-residents may have different obligations. Seek professional advice if you are unsure.
What happens if I didn’t report crypto gains in previous years?
You should make a voluntary disclosure to HMRC via their online disclosure facility. The sooner you disclose, the lower the penalties. HMRC is generally more lenient with voluntary disclosures than discovered non-compliance.
