Yes, cryptocurrency is legal in the UK. You can buy, hold, and sell Bitcoin, Ethereum, and other tokens without restriction, and the courts now formally treat digital assets as property. What crypto is not is legal tender. No shop has to accept it, and you cannot force anyone to settle a debt in Bitcoin the way you can with sterling. If a retailer does take crypto, that is a private contract on whatever terms the two of you agree.
The rest of the picture is about the rules that surround that basic freedom: which firms you can legally use, how crypto can be advertised to you, what tax you owe, and what happens to your holdings when you die.
Cryptoassets Are Recognised as Property
UK courts first treated Bitcoin as property in the 2019 case AA v Persons Unknown, where the High Court granted a freezing injunction over stolen coins. That principle now sits in statute. The Property (Digital Assets etc) Act 2025 received Royal Assent and confirms that digital assets form a distinct third category of personal property under English and Welsh law, separate from physical possessions and from traditional contractual rights.1UK Parliament. Property (Digital Assets etc) Act 2025 The Law Commission had recommended exactly this approach, arguing that the common law was flexible enough to accommodate the unusual features of crypto-tokens.2UK Law Commission. Digital Assets
In practice, property status means you have legal remedies if your tokens are stolen or misappropriated. Courts can grant freezing orders and tracing orders. Your crypto can be included in a will and passes under the same succession rules as other personal property.
What You Can and Cannot Do
Holding crypto directly is unrestricted. You can open an account with a UK-registered exchange, transfer sterling in, buy tokens, and move them to a personal wallet. You can sell them back for sterling, or swap them for other tokens.
What you cannot do as a retail investor is trade crypto derivatives. Since January 2021, the FCA has banned the sale, marketing, and distribution of crypto-linked derivatives and exchange-traded notes to retail clients. The ban covers futures, options, and contracts for difference that reference cryptoassets.3Financial Conduct Authority. PS20/10: Prohibiting the Sale to Retail Clients of Investment Products That Reference Cryptoassets Buying the underlying tokens is fine; the ban targets leveraged products that magnify losses. Professional investors meeting specific wealth and experience thresholds can still access them.
Which Firms You Can Legally Use
Every cryptoasset firm operating in the UK, including exchanges and custodian wallet providers, must be registered with the Financial Conduct Authority under the Money Laundering, Terrorist Financing and Transfer of Funds (Information on the Payer) Regulations 2017.4Financial Conduct Authority. Cryptoassets: How to Apply for Registration Operating without registration is a criminal offence.
Before using a platform, check that it appears on the FCA register. Registered firms have to run know-your-customer checks, carry out ongoing due diligence on customers, and monitor transactions for suspicious activity. The FCA’s assessment when firms apply covers anti-money-laundering policies, internal controls, and the fitness of senior management, and the regulator has rejected or forced the withdrawal of a significant number of applications since the regime began.
Using an unregistered overseas platform is legal for you as an individual, but you lose the protections that come with UK oversight, and any dispute will be governed by whatever jurisdiction the firm operates from.
Crypto Marketing Rules
Since 8 October 2023, any promotion of cryptoassets aimed at UK consumers has to be clear, fair, and not misleading, and must carry a prominent risk warning that you could lose all your money. The FCA also banned incentive schemes like refer-a-friend bonuses that platforms had used to attract new customers.5Financial Conduct Authority. FCA Sets Expectations Ahead of Incoming Crypto Marketing Rules
Only FCA-authorised firms, firms registered under the money laundering regulations, or overseas firms whose promotions have been approved by a UK-authorised person may legally promote crypto to a UK audience.6legislation.gov.uk. The Financial Services and Markets Act 2000 (Financial Promotion) (Amendment) Order 2023 Breaching the financial promotion rules is a criminal offence, and a person convicted on indictment under section 25 of the Financial Services and Markets Act 2000 faces up to two years in prison and an unlimited fine.7legislation.gov.uk. Financial Services and Markets Act 2000 – Explanatory Notes The FCA issued 146 alerts about non-compliant crypto promotions in the first 24 hours the regime took effect.8Financial Conduct Authority. FCA Issues 146 Alerts in First 24 Hours of New Crypto Marketing Regime
You may also be asked to complete a short investor categorisation and risk assessment before a firm can make certain direct-offer promotions to you. That process exists to satisfy the FCA’s rules and is not optional if the firm wants to keep promoting to you.9Financial Conduct Authority. Policy Statement PS23/6: Financial Promotion Rules for Cryptoassets
Tax on Cryptocurrency
HMRC treats cryptoassets as property for tax purposes. Most people who trade or earn crypto will run into Capital Gains Tax, Income Tax, or both. The HMRC Cryptoassets Manual is the primary guidance.10GOV.UK. Cryptoassets Manual – HMRC Internal Manual
Capital Gains Tax
Selling crypto for cash, swapping one token for another, or paying for goods with crypto all count as disposals for Capital Gains Tax. The annual exempt amount for 2026-27 is £3,000. From 6 April 2025 the rates are 18% for basic-rate taxpayers and 24% for higher-rate taxpayers.11GOV.UK. Capital Gains Tax Rates and Allowances With the exempt amount at £3,000, even modest trading activity can put you over the line.
Transfers between spouses or civil partners who lived together in the tax year do not trigger CGT, but when the receiving spouse eventually sells, their gain is worked out from your original acquisition date and cost, not from the transfer.12GOV.UK. Capital Gains Tax: Gifts to Your Spouse or Charity Gifting crypto to anyone else is a disposal at market value and follows normal CGT rules.
Income Tax on Mining, Staking, and Payment
Tokens received through mining, staking, or as payment for work are generally treated as income rather than capital. Whether the activity is a trade or miscellaneous income turns on factors like organisation, risk, and commerciality, and most individual stakers and casual miners will fall into the miscellaneous category.13GOV.UK. Cryptoassets for Individuals: Income Tax: Staking The sterling value of the tokens at the point of receipt is taxable, less allowable expenses. If you then hold the tokens and sell later at a higher price, the further gain is subject to Capital Gains Tax on top of the income you already declared.
Returns from DeFi lending and liquidity pools sit in a less certain place. HMRC consulted on the treatment, and many respondents argued for capital treatment across the board, but the government has said it is not currently pursuing specific provisions to change how DeFi rewards are taxed.14GOV.UK. The Taxation of Decentralised Finance (DeFi) Involving the Lending and Staking of Cryptoassets – Summary of Responses Each arrangement needs its own assessment, and paid advice is usually worth it if the sums are meaningful.
Deadlines and Records
Crypto gains and income are reported through Self Assessment. For the tax year ending 5 April 2025, the online return and any tax owed are due by 31 January 2026, with a second payment on account due 31 July if applicable.15GOV.UK. Self Assessment Tax Returns: Deadlines Missing these dates triggers automatic penalties.
HMRC expects records of every transaction: dates, amounts, counterparties, and sterling values at the time. Inadequate records can lead to penalties of up to £3,000. If you trade regularly, portfolio tracking software is realistically the only way to keep on top of it.
Inheritance Tax and Access to Your Keys
Crypto forms part of your estate for Inheritance Tax. The nil-rate band for 2026-27 remains £325,000, and estates below that threshold are not subject to IHT.16GOV.UK. Inheritance Tax Nil-Rate Band and Residence Nil-Rate Band Thresholds From 6 April 2026 to 5 April 2028 The allowance applies across all asset types, crypto included.
The Property (Digital Assets etc) Act 2025 makes the estate-planning side more straightforward. Digital assets can be included under intestacy rules where someone dies without a will, and executors have clearer legal footing when dealing with tokens held by the deceased.1UK Parliament. Property (Digital Assets etc) Act 2025 The real practical problem is access. If nobody knows your private keys or recovery phrases, the assets are effectively lost, even though they legally belong to your estate. Recording access instructions somewhere your executor can find them is one of the more important things a crypto holder can do.
Automatic Reporting From 2026
From 1 January 2026, the UK is bringing in the Crypto-Asset Reporting Framework. UK-based crypto service providers will have to collect transaction data on their users and report it to HMRC, with the first international exchanges of data scheduled for 2027.17GOV.UK. Domestic Reporting of UK Resident Cryptoasset Users Under the Cryptoasset Reporting Framework HMRC will have independent visibility into your crypto activity, which makes reconciling your Self Assessment return against exchange data straightforward for the tax authority. Unreported gains are far more likely to be picked up.
Where the Rules Are Heading
The current FCA registration regime is a transitional step. The Financial Services and Markets Act 2023 gives HM Treasury the power to bring cryptoassets fully within the regulated activities framework used for traditional financial services. A draft statutory instrument would create new regulated activities including operating a cryptoasset trading platform and issuing qualifying stablecoins, and introduce market abuse and disclosure regimes for crypto.18GOV.UK. Future Financial Services Regulatory Regime for Cryptoassets (Regulated Activities) – Policy Note
Fiat-backed stablecoins were initially going to be brought inside the regulated payments perimeter through changes to the Payment Services Regulations 2017, but the government decided not to proceed with that step for now. Stablecoins remain unregulated for payment purposes at present, though issuing a qualifying stablecoin will become a regulated activity under the new framework.18GOV.UK. Future Financial Services Regulatory Regime for Cryptoassets (Regulated Activities) – Policy Note
Within the next few years, crypto firms in the UK will likely need full FCA authorisation rather than registration under money-laundering rules, and the expectations placed on them will look much closer to those on banks and investment firms. For users, that should mean stronger protections and clearer rules. It will also raise firms’ compliance costs, which tend to find their way back to customers.
