-
What are digital assets in simple terms?
Digital assets are valuable items that exist online — like bitcoin, digital collectibles (NFTs), or tokens in an app. You own them through an account or wallet, not as paper or coins. They are legal to own in the UK but risky, and not the same as money in your bank.
-
Do I pay tax on cryptocurrency in the UK?
You may pay Capital Gains Tax when you dispose of cryptoassets — by selling, swapping, spending or gifting them. You may pay Income Tax when you receive crypto as earnings, mining rewards or certain staking income. You must keep records and report to HMRC when your gains exceed the annual exempt amount or you have income to declare.
-
Is cryptocurrency legal in the UK?
Yes. Owning, buying and selling cryptoassets is legal in the United Kingdom. Firms providing services must comply with FCA anti-money-laundering registration and financial promotions rules. You must also comply with HMRC tax obligations.

The FCA maintains a register of firms approved to conduct cryptoasset activities under the Money Laundering Regulations. Check the Financial Services Register before using an exchange or custodian.

-
Is bitcoin legal tender in the UK?

-
What is CARF and how does it affect UK crypto holders?
CARF (Cryptoasset Reporting Framework) requires UK crypto service providers to report customer transaction data to HMRC from 2026. You must still declare your own tax through Self Assessment — CARF helps HMRC verify returns.
-
Is crypto staking taxable in the UK?
Staking rewards are generally treated as taxable income when you receive them, based on their sterling value at that time. When you later sell those tokens, Capital Gains Tax may apply on any additional gain.
-
Is bitcoin mining taxable in the UK?
Mining rewards are usually subject to Income Tax on the value when received. If your mining amounts to a trade, different rules apply. You may also need to register for Self Assessment.
-

Yes. Swapping tokens is a disposal for UK tax. You calculate the gain or loss in pound sterling at the time of the exchange.
-

-
What is Section 104 pooling for crypto?
HMRC requires you to group each token type into a pool with an average cost. When you sell, you deduct a proportion of that average cost to calculate your gain.
-
What is the 30-day rule for crypto tax?
If you sell crypto and buy the same type back within 30 days, HMRC matching rules may link the sale to the new purchase instead of your main pool — affecting how gain is calculated.

What is a stablecoin?
A stablecoin is a crypto token designed to stay at a steady value, often pegged to the US dollar or pound. It is still a cryptoasset for UK tax — not the same as a bank account.
-
What is the difference between the digital pound and bitcoin?
The digital pound would be official Bank of England money in digital form. Bitcoin is not issued or guaranteed by the government and is much more volatile.
-

Crypto salary is usually subject to Income Tax and National Insurance like cash pay, based on the sterling value when received.

Yes, in most cases. Swapping tokens on a DEX is usually a Capital Gains Tax disposal. Rewards from liquidity pools, lending or yield farming are often Income Tax when received. You must keep on-chain records — exchange statements rarely cover DeFi.
-
What records does HMRC expect for crypto?
For each transaction: date, type, token, quantity, sterling value, fees, platform or wallet, and a reference ID. Keep records for at least five years after the Self Assessment deadline. A free CSV template is available at digital-assets.co.uk/templates/.
-
Which SA108 boxes do I use for crypto in the UK?
From 2024/25 returns, use the Cryptoassets section on SA108: box 13.2 for disposal proceeds, 13.3 for allowable costs, 13.4 for gains, 13.5 for losses. Report crypto income separately on SA100, not in these boxes.
-
Do I report crypto if proceeds exceed £50,000 but gains are under £3,000?

Choose software that applies HMRC Section 104 pooling and 30-day rules — such as Koinly, Recap or Coinpanda. HMRC does not endorse any tool. Review all figures before filing Self Assessment.

Search the firm’s exact legal name at fca.org.uk/firms/firm-search. Check cryptoasset permissions and the Firm Reference Number. MLR registration alone is not full authorisation until October 2027.

-
When should I hire a crypto accountant in the UK?
Consider an accountant for heavy DeFi, possible trading income, HMRC enquiries, cross-border residence, or large portfolios. Bring CSV exports and wallet lists. Verify ICAEW/ACCA/CTA qualification and crypto experience.
-
Do I pay tax on crypto gifts in the UK?
Often, yes. Giving crypto to anyone other than your spouse or civil partner counts as a disposal at market value, so Capital Gains Tax can be due even though no money changed hands. Gifts between spouses and civil partners are on a no gain, no loss basis, and gifts to registered charities usually have relief. Receiving a gift is not taxed, but the value at receipt becomes your acquisition cost.
-
Is transferring crypto between my own wallets taxable in the UK?
No. Moving crypto between wallets or accounts you own is not a disposal, so no Capital Gains Tax arises — you still own the same asset. Keep records of the transfer so it is not mistaken for a sale, and note that a network fee paid in crypto is itself a small disposal of the tokens used to pay it.
-
What happens if I don't declare crypto to HMRC?
HMRC can charge the unpaid tax plus interest and penalties — and penalties are much higher when non-disclosure is deliberate. UK exchanges already share customer data with HMRC, and CARF reporting from January 2026 widens that net, so undeclared gains increasingly trigger nudge letters or compliance checks. If you are behind, a voluntary disclosure before HMRC contacts you usually means lower penalties.
-
Can HMRC track my crypto?
Yes, in most practical cases. UK exchanges verify identity and provide customer data to HMRC, the Cryptoasset Reporting Framework (CARF) brings standardised reporting from January 2026 including overseas platforms, and public blockchains are analysable. Assume HMRC can connect exchange accounts to you, and self-report accurately rather than relying on crypto being invisible.
-
Do you pay council tax on crypto profits in the UK?
No — that is a myth. Council tax is charged on your home, not your income or investments, and crypto profits never affect it. The taxes that can actually apply to crypto are Capital Gains Tax when you sell, swap, spend or gift at a profit, and Income Tax on staking, mining or being paid in crypto.
-
Is crypto gambling legal in the UK?
Only on sites licensed by the Gambling Commission — and very few crypto casinos are. Using an unlicensed offshore crypto casino means no UK consumer protections and a high scam risk, and operators break UK law by serving GB customers. Tax-wise, gambling winnings are generally not taxed, but spending crypto to place a bet is still a Capital Gains Tax disposal.
