UK Introduces Strict Crypto Data Reporting Requirements, Effective January 1, 2026

From January 1, 2026, UK crypto companies will be obligated to collect and report detailed user and transaction data under new reporting rules. The move comes as part of the UK’s Crypto Asset Reporting Framework (CARF), a global initiative aimed at enhancing tax transparency in digital asset markets. This framework requires firms to gather comprehensive user information including identity, address, TIN, and transaction details for each user. This aligns with international efforts led by the OECD to standardize crypto reporting and tackle tax evasion. The UK government has stated that failure to comply could result in fines of up to £300 per user.
