United Kingdom — Financial Regulatory Jurisdiction

The United Kingdom (UK) is one of the most significant global financial centres with the City of London as its hub. After Brexit (2020), the UK operates as an independent regulatory jurisdiction outside the EU, but has retained many EU regulatory standards or developed them independently.

• Financial supervision: FCA (Financial Conduct Authority), PRA (Prudential Regulation Authority, part of Bank of England)
• Central bank: Bank of England
• Tax authority: HMRC (His Majesty's Revenue and Customs)
• Anti-money laundering: National Crime Agency (NCA) as Financial Intelligence Unit (FIU)
• CRS participation: Yes — UK is a CRS Early Adopter (data collection from 2016, first exchange 2017)
• Brexit particularity: UK continues to apply FATCA and has retained its own CRS regulations

The UK was an early pioneer in international tax transparency. As part of the G5 (together with Germany, France, Italy, Spain), the UK signed a multilateral agreement in 2013 on the pilot project for automatic information exchange, from which the OECD CRS later emerged.

The UK-FATCA agreement (IGA) with the USA was signed in 2012, the first country in the world to sign a FATCA IGA based on the model agreement. After the Brexit referendum in 2016 and withdrawal from the EU single market on 31 December 2020, the UK is developing its own regulatory architecture. The UK retained the CRS regime and adapted financial regulation through the Financial Services and Markets Act 2023 to the post-Brexit reality.

UK financial regulation extends to:

• Banks and financial institutions: Dual-regulation by FCA (conduct) and PRA (stability)
• Insurance: PRA supervision for solvency, FCA for consumer protection
• Capital markets: FCA supervision of stock exchange trading, prospectuses, market abuse
• Tax transparency: CRS, FATCA (UK-US IGA), DAC6-equivalent UK MDR rules
• Overseas Territories and Crown Dependencies: British Overseas Territories (Cayman Islands, BVI, etc.) and Crown Dependencies (Jersey, Guernsey, Isle of Man) have their own but UK-compatible rules

Key regulatory requirements in the UK:

• UK CRS: UK financial institutions must report annually to HMRC on accounts of foreign taxpayers (deadline: 31 May)
• UK FATCA: UK financial institutions report US account data to IRS via HMRC
• UK MDR: UK Mandatory Disclosure Rules (successor to DAC6 post-Brexit)
• Register of Overseas Entities: Foreign real estate owners must disclose beneficial owners in Companies House register
• Senior Managers and Certification Regime (SMCR): Personal accountability of senior managers in financial institutions
• CRS 2.0: From 2026, expanded CRS regulations apply (International Tax Compliance Amendment Regulations 2025), including mandatory HMRC registration and crypto-asset reporting obligations

"United Kingdom — Financial Regulatory Jurisdiction" was classified under theme "Steuer". Correct is "Jurisdiktion". National laws and authorities are classified by subject matter, not as Jurisdiction. Country profiles are classified as Jurisdiction.
