With cryptocurrency adoption surging in the UK, understanding your tax obligations is crucial to avoid penalties. Her Majesty’s Revenue and Customs (HMRC) treats crypto as property rather than currency, meaning transactions can trigger tax events. This guide breaks down everything you need to know about paying taxes on crypto income in the UK.
## How HMRC Classifies Cryptocurrency
HMRC doesn’t recognise cryptocurrencies like Bitcoin or Ethereum as traditional money. Instead, they’re categorised as “cryptoassets” – a form of property subject to either Capital Gains Tax (CGT) or Income Tax. Your tax liability depends entirely on how you acquire and use your crypto:
– **Investment activity**: Typically falls under CGT when sold
– **Business activity**: Usually treated as taxable income
– **Mining/staking**: Considered income if done professionally
## When You Owe Crypto Taxes in the UK
You must report crypto transactions when you “dispose” of assets. Key taxable events include:
– Selling crypto for GBP or other fiat currencies
– Trading one cryptocurrency for another (e.g., BTC to ETH)
– Using crypto to purchase goods or services
– Gifting crypto to anyone except your spouse
– Receiving crypto through mining, staking, or airdrops
Note: Simply holding crypto or transferring between your own wallets isn’t taxable.
## Calculating Your Crypto Tax Liability
### For Capital Gains Tax (CGT)
Apply when selling or swapping crypto investments:
1. Calculate gain: Disposal value minus original cost (including fees)
2. Deduct your annual CGT allowance (£6,000 for 2023/24; £3,000 from April 2024)
3. Tax rates:
– 10% for basic rate taxpayers
– 20% for higher/additional rate taxpayers
### For Income Tax
Applies to crypto earned through:
– Employment payments
– Mining/staking rewards
– Airdrops received in business context
– Market value at receipt is taxed at your income tax rate (20%/40%/45%)
## Essential Record-Keeping Requirements
Maintain detailed records for at least 5 years after filing:
– Transaction dates and types
– Asset amounts in crypto and GBP value
– Wallet/exchange addresses
– Receipts for purchases and sales
– Calculations for cost basis and gains
Use crypto tax software like Koinly or CoinTracker to automate tracking.

## Penalties for Non-Compliance

– Daily £10 penalties after 3 months
– Up to 100% of owed tax in additional fines
– Criminal prosecution in severe cases
## Crypto Tax FAQs
**Q: Is crypto-to-crypto trading taxable?**
A: Yes. Every trade between different cryptocurrencies counts as a disposal for CGT purposes.
**Q: What if I lost money on crypto investments?**
A: Report capital losses to offset gains. Unused losses carry forward indefinitely.
**Q: Are NFT transactions taxable?**
A: Yes. NFTs follow the same CGT rules as other cryptoassets when sold or traded.
**Q: How do I value crypto for tax purposes?**
A: Use GBP market value at transaction time. HMRC accepts exchange rates from reputable sources like CoinMarketCap.
**Q: Do DeFi transactions trigger taxes?**
A: Yes. Providing liquidity, yield farming, and loan rewards are typically taxable events.
Staying compliant requires meticulous record-keeping and understanding disposal events. When in doubt, consult a crypto-specialised accountant. HMRC’s Cryptoassets Manual provides further guidance for complex cases.
