Yes — most UK crypto activity is taxable. You pay capital gains tax when you sell, swap or spend at a profit, and income tax when you're paid in crypto or earn it from staking. Simply holding is tax-free. Here's the plain-English version.
Important Risk Warning
This is not financial advice. Cryptocurrency investments are highly volatile. The value of your investment can go down as well as up, and you could lose all the money you invest. Don't invest unless you're prepared to lose all the money you put in.
Yes, you pay tax on crypto in the UK — but not on all of it, and not just because you own some. You owe capital gains tax when you sell, swap or spend crypto at a profit above your annual allowance, and income tax when crypto lands in your hands as payment, staking rewards or an airdrop you did something to earn. Buying and simply holding? That's tax-free until you do something with it.
That distinction between capital and income is the whole game. Miss it and you'll either overpay or, more likely, under-declare and hear from HMRC later.
You pay when there's a "disposal" or when crypto arrives as income. A disposal is any time you part with a coin — selling for pounds, swapping BTC for ETH, spending it, or gifting it to anyone other than your spouse. Income is crypto you receive: salary paid in tokens, staking or mining rewards, or airdrops tied to a service you provided.
Holding, moving coins between your own wallets, and buying crypto with pounds are all non-events for tax. So is gifting to a spouse or civil partner. Everything else is likely to touch one of the two taxes.
Capital gains tax applies to the profit when you dispose of crypto you were holding as an investment. Income tax applies when crypto is earned. They're taxed at different rates and against different allowances, which is why lumping everything together is the classic mistake.
| Situation | Tax type | 2026 allowance | Rate |
|---|---|---|---|
| Selling/swapping/spending at a profit | Capital gains | £3,000 exempt | 18% or 24% |
| Paid a salary or fee in crypto | Income (+ NI) | Personal allowance | 20%–45% |
| Staking, mining, some airdrops | Income | £1,000 trading allowance may apply | 20%–45% |
| Buying and holding | None | — | 0% |
The rates on the income side track your normal income tax band. On the capital side, the 18%/24% split depends on how much of the gain sits in the basic-rate band versus above it. Our capital gains guide and our income tax guide for staking, mining and airdrops go through the maths.
There's no limit on holding — you can sit on any amount of crypto tax-free. The tax only bites when you dispose of it or earn it. What has a limit is the tax-free profit: the £3,000 capital gains annual exempt amount for 2026, down sharply from the £12,300 it was a few years back.
That shrinking allowance is why far more ordinary investors now cross the line than used to. Realise a £4,000 gain and £1,000 of it is taxable. It doesn't take a whale portfolio to get there anymore — a couple of good years and one sell-off will do it.
Increasingly, yes. Under the Crypto-Asset Reporting Framework, UK and international exchanges are collecting and sharing customer transaction data with tax authorities, and HMRC has been sending "nudge letters" to people it believes have undeclared gains. We cover the mechanics in our piece on CARF crypto data-sharing.
The honest read: assuming HMRC can't see your on-exchange activity was never wise, and in 2026 it's simply wrong. If you've disposed of crypto at a gain above the allowance in prior years and didn't declare it, the sensible move is to correct it before a letter arrives, not after.
Do I pay tax if I just buy and hold crypto? No. Buying crypto with pounds and holding it creates no tax charge, however much it rises on paper. Tax only applies when you dispose of it or receive crypto as income.
Do I pay tax when swapping one coin for another? Yes. Swapping BTC for ETH is a disposal of the BTC, and any gain over your annual allowance is taxable — even though no pounds changed hands and nothing hit your bank.
Is there a tax-free amount for crypto in the UK? Yes, the £3,000 capital gains annual exempt amount for 2026. Gains up to that figure across all your assets are tax-free; anything above is taxed at 18% or 24%.
Do I pay tax on staking rewards? Usually yes, as income at the sterling value when you receive them. If you later sell those coins for more, the increase is a separate capital gain. See our staking tax guide.
What if I made a loss? Losses aren't taxed, and you can register them with HMRC to offset gains in the same or future years. Claiming losses is one of the few genuine ways to cut a crypto tax bill — our tax losses guide explains how.
Pull a full year of transactions and sort each line into one of three buckets: disposal, income, or non-event. That single exercise tells you whether you owe anything and which return it goes on. If the totals cross HMRC's thresholds, our Self Assessment walkthrough takes it from there. This isn't financial advice — for a complicated position, a crypto-savvy accountant earns their fee.
