The UK sits outside the EU’s MiCA framework post-Brexit but inside its own established crypto regulatory perimeter. The FCA maintains a register for crypto-asset firms, HMRC publishes detailed guidance on the tax treatment of crypto disposals, and the practical experience of accepting Bitcoin for individuals and small merchants is straightforward.

Regulator and registration

The UK does not have a direct MiCA equivalent. Instead:

  • The Financial Conduct Authority (FCA) is the AML / CTF supervisor for UK cryptoasset businesses under the Money Laundering, Terrorist Financing and Transfer of Funds (Information on the Payer) Regulations 2017 (the MLRs, as amended).
  • Crypto firms providing in-scope services in the UK must register with the FCA under MLRs Regulation 8L / Regulation 9 before commencing those services. The in-scope services are defined in Regulation 14A (exchanges, custodial wallets, certain transfer services).
  • The Travel Rule applies to UK crypto-asset transfers above the threshold.
  • A new full-authorisation regime for cryptoasset firms is expected to come into force on 25 October 2027, after which firms will need full FCA authorisation rather than just AML registration. HM Treasury and the FCA have published roadmaps and consultation papers on this transition.

Who this affects:

  • Crypto exchanges with UK customers → FCA register.
  • UK-based custodial wallet providers → FCA register.

Who this does not affect:

  • An individual holding Bitcoin in a self-custodial wallet.
  • A creator accepting Lightning tips to their own Lightning Address.
  • A UK merchant accepting Bitcoin for goods or services.

Tax framework

HMRC treats Bitcoin as a chargeable asset, not currency. Disposals by individuals are capital gains events:

  • A disposal includes selling Bitcoin for GBP, swapping for another crypto, paying for goods or services, or gifting (with limited exceptions).
  • The gain or loss is calculated against the acquisition cost using HMRC’s pooling rules (Section 104 holding, with same-day and 30-day matching).
  • The annual exempt amount for tax year 2025/26 is £3,000. This has been reduced repeatedly — £6,000 in 2023/24 and £12,300 in 2022/23. Verify the current figure against HMRC’s published rates before relying on it.
  • For disposals from 30 October 2024 onwards, CGT rates are 18% within the basic-rate band and 24% in the higher and additional-rate bands. Pre–30 October 2024 disposals used the older 10%/20% structure — relevant if you are amending earlier returns.
  • CARF (Crypto-Asset Reporting Framework). From 1 January 2026, UK crypto service providers must collect in-scope data under the OECD CARF standard. First reports to HMRC are due in 2027 covering 2026 activity. Aligns UK with the international information-exchange standard.

For Lightning payments received as income: the GBP value at the time of receipt is the income event. A later disposal of those sats is a separate capital-gains event against the receipt-time acquisition cost.

Trading as a business (frequent transactions with the badges of trade) is taxed under the income tax rules for trading profits, not CGT. The line between “investor” and “trader” matters and is fact-specific.

Hire a UK accountant who has handled crypto. This is not tax advice.

Best Lightning wallets for individuals in the UK

For UK individuals and creators:

  • For self-custody: Alby — Alby Hub or Alby Cloud, your keys on your device, Lightning Address out of the box.
  • For mobile self-custody: Phoenix — splicing-based, mobile, self-custodial.
  • For easiest onboarding: Wallet of Satoshi — custodial, simplest setup. UK-available.

Strike launched in the UK around the same time as the EU in 2024. For senders, Strike is a viable UK-based option; for receivers, the processor side is more relevant.

Best payment processors for UK merchants

For UK cafés, shops, online merchants:

  • Self-hosted: BTCPay Server — no transaction fees, integrates with most ecommerce platforms.
  • Hosted, GBP settlement available: OpenNode, Strike, Speed. All UK-accessible; verify current fiat-settlement currencies before relying on GBP specifically.

The editorial bias is toward BTCPay Server for any merchant comfortable with the technical setup. Hosted processors are appropriate when the merchant wants a single point of accountability and a single bill.

Practical setup

The same pattern applies as elsewhere:

  1. Pick a wallet or processor.
  2. Test with a small amount.
  3. Display a QR code or embed a payment widget.
  4. Keep detailed records — particularly important in the UK where HMRC expects records of every disposal.

FAQ

Is Bitcoin legal in the UK? +

Yes. Bitcoin is legal to hold, send, receive, and use as a means of payment in the UK. Post-Brexit the UK is outside MiCA. The Financial Conduct Authority (FCA) is the AML/CTF supervisor for UK cryptoasset businesses under the Money Laundering, Terrorist Financing and Transfer of Funds (Information on the Payer) Regulations 2017 (MLRs). Crypto firms providing in-scope services in the UK must register with the FCA under MLRs Regulation 8L / 9. A new cryptoasset regime requiring full authorisation rather than just registration is expected to come into force on 25 October 2027.

How is Bitcoin taxed in the UK? +

HMRC treats Bitcoin as a chargeable asset, not currency. Disposals by individuals are capital gains events. The annual exempt amount is £3,000 for tax year 2025/26 (down from £6,000 in 2023/24 and £12,300 before that). On gains above the exempt amount, CGT rates from 30 October 2024 onwards are 18% at the basic rate band and 24% at the higher and additional rate bands. From 1 January 2026 UK crypto service providers must collect data under the OECD Crypto-Asset Reporting Framework (CARF), with first reports to HMRC in 2027 covering 2026 activity. Trading-as-a-business is taxed under different rules. This is not tax advice.

Do I need to register with the FCA to accept Bitcoin as a merchant? +

No. Accepting Bitcoin for goods or services is not, by itself, a regulated activity. The FCA register requirement applies to UK-based firms providing crypto-asset services as defined in MLRs Regulation 14A (exchanges, custodial wallets, certain transfer services). A merchant taking Bitcoin in exchange for coffee is not in scope.
