Cryptocurrency in the United Kingdom: regulation, taxes and licensing
In short. Crypto is legal in the United Kingdom, and since February 2026 the country has had a proper statute for it rather than a patchwork of separate requirements. A private investor pays capital gains tax at 18% or 24% depending on their income. Firms need FCA authorisation, and the application window opens on 30 September 2026.

Who regulates crypto in the United Kingdom
Until 2026 the industry sat in an odd position here: exchanges registered with the FCA only for anti-money-laundering purposes, advertising fell under the financial promotions rules, and no statute on crypto assets existed at all.
One arrived on 4 February 2026. The new regulations created the first comprehensive legal framework and named the activities that require authorisation: exchange, custody, staking and stablecoin issuance.
The timetable is unusually firm. The application window opens on 30 September 2026 and closes on 28 February 2027. A platform that has not applied within it cannot lawfully operate in the country after 25 October 2027. This is not a gradual tightening but a date after which the market will simply look different.
Stablecoins were split by consequence. Retail ones fall to the FCA. Those large enough to matter for financial stability go to the Bank of England and must hold reserves in central bank money. The permanent minimum capital for a qualifying stablecoin issuer is £350,000.
Tax: capital gains, and a threshold worth remembering
HMRC treats crypto as property, so disposing of it triggers capital gains tax. Disposal is not only selling for pounds: swapping one coin for another and paying for something in crypto both count.
The rate depends on your income rather than how long you held: 18% for basic-rate taxpayers and 24% for everyone else. Unlike Germany or Portugal, the British system rewards patience with nothing at all.
There is an annual exempt amount of £3,000 of gains. Unlike the German threshold this is a genuine allowance: exceed it and you pay on the excess, not on everything.
Mining, staking, airdrops and being paid in crypto are not capital gains. They are income, taxed at income tax rates at the moment of receipt.
Since 1 January 2026 a reporting layer has applied as well. Under the international framework for crypto-asset reporting, platforms collect customer information and pass it to tax authorities, and from the 2026/27 year the UK begins receiving data from other jurisdictions automatically.

Briton James Howells has been trying since 2013 to dig up a drive holding 8,000 bitcoin from a Newport landfill. In 2025 the courts finally refused: whatever enters the tip belongs to the council.
Common questions
How long must I hold crypto in the UK to avoid tax?
Holding period is irrelevant. Unlike Germany or Portugal there is no long-term relief: the rate is 18% or 24% depending on your income.
What does the £3,000 allowance do?
It is a genuine allowance — you pay tax on gains above it, not on the whole gain.
Is swapping one coin for another taxable?
Yes. It is a disposal and the gain is computed exactly as if you had sold for pounds.
What happens to exchanges that do not apply to the FCA?
After 25 October 2027 they cannot lawfully operate here. The window runs from 30 September 2026 to 28 February 2027.
Is staking taxed?
Yes, but not as a capital gain. Rewards are income at the moment of receipt and taxed at income tax rates.
