Crypto License in the United Kingdom

A UK crypto license is FCA authorization under The Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2026 (SI 2026/102), the statutory instrument made by HM Treasury on 4 February 2026 that brings cryptoasset activities within the FSMA perimeter. From 25 October 2027, firms carrying on regulated cryptoasset activities by way of business in the UK must hold a Part 4A FSMA permission from the Financial Conduct Authority (FCA) — the previous AML-only Money Laundering Regulations (MLRs) 2017 registration is no longer sufficient.

Nine new regulated activities are introduced: issuing qualifying stablecoin in the UK, safeguarding qualifying cryptoassets, arranging for another to safeguard, operating a qualifying cryptoasset trading platform (QCATP), dealing in qualifying cryptoassets as principal or as agent, arranging deals, and qualifying cryptoasset staking. Public offers of qualifying cryptoassets and admissions to trading become separate designated activities under Part 5A FSMA, alongside a new market abuse framework.

The FCA authorization gateway opens 30 September 2026 and closes 28 February 2027. Firms that apply during this window benefit from a saving provision allowing continued operation while the application is determined. Firms registered under the MLRs 2017 do not automatically convert — each must apply separately for Part 4A authorization. Pre-application support (PASS) opens 11 May 2026, with FCA meetings scheduled from July 2026.

Non-UK firms have two practical routes during transition: apply for Part 4A authorization directly, or operate via an FCA-authorized s.21 approver for financial promotions to UK customers until 25 October 2027 (after which only pre-existing contract promotions remain available without authorization). The UK regime does not provide EU passporting — for EU market access, a separate CASP license under MiCA is required.

UK crypto regulation rests on the Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2026 (SI 2026/102), with three regulators sharing oversight: the Financial Conduct Authority (FCA) (authorization, conduct, prudential rules), HM Treasury (HMT) (perimeter and policy via statutory instruments), and the Bank of England (BoE) (systemic stablecoins and financial stability). The Regulations were made by HM Treasury on 4 February 2026 under powers conferred by the Financial Services and Markets Act 2023 (FSMA 2023, Schedule 6) — for commencement dates and the application window see Quick Facts above.

The nine regulated cryptoasset activities

SI 2026/102 amends the FSMA (Regulated Activities) Order 2001 to designate the following as new regulated activities, each requiring Part 4A FSMA permission:

• Issuing a qualifying stablecoin in the UK.
• Safeguarding qualifying cryptoassets and relevant specified investment cryptoassets.
• Arranging for another person to safeguard qualifying cryptoassets.
• Operating a qualifying cryptoasset trading platform (QCATP).
• Dealing in qualifying cryptoassets as principal.
• Dealing in qualifying cryptoassets as agent.
• Arranging deals in qualifying cryptoassets.
• Qualifying cryptoasset staking.

Public offers of qualifying cryptoassets and admissions to a regulated trading platform are designated activities under Part 5A FSMA, alongside a new market abuse framework with insider dealing, market manipulation, and disclosure obligations.

Authorization timeline and the gateway

The FCA authorization gateway opens on 30 September 2026 and closes on 28 February 2027. Firms wishing to undertake any of the nine regulated activities must hold Part 4A permission before 25 October 2027. Pre-application support (PASS) is available from 11 May 2026, with FCA pre-application meetings scheduled from July 2026 onward. Existing FCA-authorized firms intending to undertake new cryptoasset activities apply via Variation of Permission (VoP) rather than a full new authorization.

MLR registration is not Part 4A authorization

Firms registered under the Money Laundering Regulations 2017 (MLRs) do not automatically transition to FSMA authorization — each firm must submit a separate Part 4A application. The MLR regime continues to apply to anti-money laundering and counter-terrorism financing obligations alongside the new FSMA permission. Firms applying for MLR registration after 31 July 2027 are unlikely to receive a determination before the new regime commences, so new applicants are encouraged to focus directly on the FSMA gateway.

Saving and transitional provisions

Part 7 of SI 2026/102 establishes two protective mechanisms during the transition. The saving provision applies to firms that submit a Part 4A application during the gateway window (30 September 2026 – 28 February 2027) — these firms continue operating under the existing regime until the application is finally determined, with a backstop date of 25 October 2029. The transitional provision applies to firms whose application is refused (and no longer open to review) or that do not apply at all — these firms enter a wind-down regime allowing them to service pre-existing UK contracts only.

Use of s.21 approvers in transition

Until 25 October 2027, non-UK crypto firms and firms without Part 4A permission may continue using an FCA-authorized s.21 approver to approve their financial promotions to UK consumers under section 21 of FSMA 2000. After commencement of the new regime, firms that have not applied for authorization lose access to s.21 approval and may only communicate promotions relating to pre-existing contracts.

Property (Digital Assets etc) Act 2025

Adjacent to the FCA regime, the Property (Digital Assets etc) Act 2025 (Royal Assent 2 December 2025) recognises certain digital assets as a distinct form of personal property in English law. This gives English courts clearer ground to treat crypto tokens as property that can be owned, transferred, and enforced against — strengthening the legal basis for custody contracts, insolvency proceedings, and cross-border disposal.

Register of cryptoasset firms

Authorized firms appear on the Financial Services Register, the FCA’s public register of authorized persons. The Register lists Part 4A permissions held, any conditions imposed, and disciplinary history. The FCA publishes a separate warning list of unauthorized firms targeting UK consumers, updated regularly. Once the new regime commences, firms must monitor the Register to verify their counterparties’ permissions before contracting.

The FSMA 2023 transition replaces narrow AML-only MLR registration with full Part 4A FSMA authorization, expanding scope from a handful of MLR-defined activities to nine regulated cryptoasset activities plus two Part 5A designated activities under SI 2026/102. Three structural changes drive firm-level planning: regulatory scope, prudential and conduct standards, and senior-management accountability under SMCR. The shift transforms supervision from anti-money laundering compliance into full financial-services oversight — capital adequacy, governance, operational resilience, conduct, consumer protection, and market integrity all enter the supervisory perimeter.

What changes at commencement on 25 October 2027

• From AML supervision to FSMA authorization: the FCA assesses the firm as a regulated financial-services entity, not as an AML-regulated business. Threshold Conditions apply — adequate resources, suitability, effective oversight.
• Senior Managers and Certification Regime (SMCR): senior managers carry personal accountability for prescribed responsibilities. Each Senior Management Function must be pre-approved by the FCA. Certification staff must be assessed annually as fit and proper.
• Consumer Duty: firms must deliver good outcomes for retail customers across products, price, customer understanding, and support. Documented monitoring of customer outcomes becomes mandatory.
• Operational resilience: identification of important business services, impact tolerances, mapping of resources, and severe-but-plausible scenario testing — supervised by the FCA from day one of authorization.
• Prudential capital and safeguarding: regulatory capital requirements (subject to the FCA’s prudential consultation), safeguarding of qualifying cryptoassets and customer money, and dedicated CRYP rules in the FCA Handbook.
• Market abuse framework: insider dealing, market manipulation, and disclosure obligations apply to relevant qualifying cryptoassets under Part 5A FSMA, with insider lists and surveillance obligations on trading platforms.

The gateway window and how to use it

The authorization gateway opens 30 September 2026 and closes 28 February 2027. The FCA expects to determine applications submitted during this window before regime commencement, in submission order. Firms that submit a complete application during the window benefit from the saving provision in Part 7 of SI 2026/102: they continue operating under the existing regime while the application is under review, up to a backstop of 25 October 2029.

Pre-application support is available from 11 May 2026 through the FCA Pre-Application Support Service (PASS). Pre-application meetings begin July 2026 and are scheduled on request — these meetings allow firms to test their business model, perimeter analysis, and proposed permissions with the FCA before formal submission.

Firms registered under the Money Laundering Regulations 2017 do not transition automatically. Each MLR-registered firm must submit a separate Part 4A application. The FCA’s MLR registration window closes for new applications on 31 July 2027 — applications submitted after this date are unlikely to be determined before the new regime starts.

What happens if a firm misses the gateway

Firms that do not apply during the gateway window (or that apply later) lose access to the saving provision. Three outcomes are possible:

• Apply outside the window: permitted, but the scope of authorized activities may be limited until determination. The saving provision does not apply.
• Refused application: entry into the transitional provision — a wind-down regime allowing the firm to service pre-existing UK contracts only, until obligations are discharged.
• No application: the firm must exit UK cryptoasset business by 25 October 2027. Continuing without Part 4A permission is a criminal offence under section 19 of FSMA 2000.

Linked consultations and FCA Handbook

The detailed FCA rulebook is being finalized through 2026 across multiple consultations: CP25/14 (stablecoin issuance and cryptoasset custody), CP25/40 (regulating cryptoasset activities), CP25/41 (admissions, disclosures, and market abuse), CP25/42 (prudential regime for cryptoasset firms), and CP26/13 (perimeter guidance, April 2026). Final FCA rules will be set out in 2026 and codified in a new Cryptoassets Sourcebook (CRYP) within the FCA Handbook, with rule sets from CASS (client assets), SYSC (systems and controls), and Consumer Duty extended to cryptoasset firms.

The UK FCA license and the EU’s MiCA CASP license are the two leading European routes for crypto businesses, but they serve fundamentally different strategic positions: FCA gives global recognition and direct access to UK institutional investors without EU passporting, while MiCA grants a single CASP authorization valid across all 27 EU and EEA member states.

When the UK FCA license is the better fit

• Target market is the UK: direct access to the UK’s deep capital market, sterling banking, and institutional investors.
• Global recognition matters: FCA registration carries strong international weight in banking due-diligence and partner onboarding.
• UK-resident leadership: founders or directors based in the UK can satisfy the residency and physical-office tests without re-domiciliation.

When the MiCA CASP license is the better fit

• EU-wide scaling priority: single authorization covers 27 markets without re-licensing in each.
• Lower capital/cost in some jurisdictions: MiCA CASP via Lithuania, Cyprus, or Czech Republic can be cheaper to set up than UK FCA.
• Time pressure: straightforward MiCA applications close in 3–4 months versus 6–12 months for FCA.

For firms targeting both markets, the practical sequence is to obtain the MiCA CASP license first (faster, EU-wide) and add UK FCA registration later — or use the S21 Financial Promotions alternative (see below) to lawfully reach UK clients without a UK incorporation.

The s.21 financial promotions route lets non-UK crypto firms reach UK customers without holding their own FCA authorization, by partnering with an FCA-authorized s.21 approver that signs off each financial promotion under section 21 of FSMA 2000. The route remains available until regime commencement on 25 October 2027 — after which only pre-existing-contract promotions can be communicated without authorization. Under section 21 of the Financial Services and Markets Act 2000, a firm without Part 4A permission can communicate financial promotions to UK consumers only if those promotions are approved by an FCA-authorized s.21 approver. The FCA has confirmed transitional rules for s.21 use during the gateway window and at regime commencement.

Who can use an s.21 approver

Cryptoasset firms that are not authorized under FSMA and not registered under the MLRs 2017 (including overseas firms) may use an s.21 approver to approve their cryptoasset financial promotions and communicate legally to UK consumers. The s.21 approver remains responsible to the FCA for the approved promotion under the financial-promotions perimeter — approvers cannot lawfully approve promotions for firms conducting regulated activities without the necessary permissions.

How the s.21 route works in the transition

1. Foreign-licensed entity: the cryptoasset firm operates under a recognized license in another jurisdiction (CASP under MiCA, MSB in Canada, or similar).
2. FCA-authorized approver: the firm contracts an FCA-authorized UK firm holding s.21 approver status to review and approve its financial promotions.
3. Promotion approval per campaign: each marketing communication intended for UK consumers is reviewed and approved by the s.21 approver before publication; the approver is liable for the promotion’s compliance.
4. FCA reporting by the approver: the s.21 approver reports approved cryptoasset promotions to the FCA on the schedule required by the FCA’s financial-promotions regime.

What changes at the gateway window and at commencement

The FCA has published direct guidance on s.21 use for cryptoasset firms. Three scenarios:

• Firm applies during the gateway window (30 September 2026 – 28 February 2027): may continue using its s.21 approver until the Part 4A application is finally determined.
• Firm does not apply during the gateway window: may continue using the s.21 approver until the new regime commences on 25 October 2027. After commencement, if the firm has not been authorized, it enters the transitional provision and can communicate promotions only relating to pre-existing UK contracts.
• Firm becomes authorized under Part 4A: may communicate its own financial promotions directly and no longer requires an s.21 approver.

S21 vs full Part 4A authorization: trade-offs

• Faster setup: contracting an s.21 approver typically takes 4–8 weeks versus the multi-month Part 4A application process.
• Lower regulatory load: no UK office, no UK-resident SMCR appointments, no Threshold Conditions assessment — but ongoing approver fees, typically £3,000–10,000 (~$3,800–12,700) per month plus per-campaign approval costs.
• Strict scope: s.21 covers financial promotions to UK consumers only. The firm cannot hold customer money or cryptoassets in the UK or carry on regulated activities through the s.21 route.
• Approver dependency: business continuity depends on the s.21 approver’s continued FCA authorization; if the approver is restricted or loses status, the firm loses its UK promotions channel.
• Transitional ceiling: s.21 is not a long-term substitute for Part 4A authorization. After 25 October 2027, firms without Part 4A permission lose access to new-customer promotions in the UK.

When the s.21 route fits

The s.21 route works best for non-UK firms that already hold a recognized cryptoasset license elsewhere (MiCA CASP, MSB, VASP), want to test or scale UK customer acquisition while preparing a Part 4A application, or operate a business model that does not require holding UK customer assets directly. It is not a substitute for Part 4A authorization if the firm intends to operate as a UK qualifying cryptoasset trading platform, hold qualifying cryptoassets in custody, issue qualifying stablecoin in the UK, or build a UK-resident team.

UK-licensed crypto companies pay corporate tax on profits at 19% under £50,000 (~$63,500) and 25% above £250,000 (~$317,500), with a tapered rate between thresholds. HMRC (Her Majesty’s Revenue and Customs) treats cryptocurrencies as property rather than currency, so capital gains tax applies to disposals and income tax applies to mining and payment income. Most cryptoasset trading services are exempt from VAT.

• Corporate tax: 19% (profits under £50,000 (~$63,500)). 25% (profits above £250,000 (~$317,500)). Tapered rate between thresholds.
• HMRC asset treatment: cryptocurrencies are treated as assets, not currency. Tax treatment depends on activity (investing, mining, trading, payment). HMRC publishes the Cryptoassets Manual covering all common scenarios.
• Capital Gains Tax (CGT): applies on disposal of cryptoassets — selling, exchanging for fiat, or swapping for another asset. Calculated on the gain over base cost.
• Income Tax: applies when cryptocurrency is received as payment for goods or services. Value calculated at market price on receipt date.
• Mining income: taxable as income at the cryptocurrency’s market value at the time of receipt.
• VAT: sale and purchase of cryptocurrencies generally exempt. Use of crypto to pay for goods or services may attract VAT depending on transaction type.
• Stamp duty: may apply on shares, land, or real-estate purchases settled in cryptocurrency.

UK crypto tax vs other jurisdictions

The UK’s 19–25% corporate tax sits in the middle range for major crypto jurisdictions — higher than Switzerland’s canton-dependent rates and Singapore’s flat 17%, comparable to most EU MiCA states, lower than several US states.
