UK Tax Authority to Enforce Crypto Exchange Data Sharing from 2026
Starting January 1, 2026, UK-based cryptocurrency exchanges, brokers, and wallet providers will be required to submit detailed customer data to His Majesty’s Revenue and Customs (HMRC). The mandate aligns with the OECD’s Cryptoasset Reporting Framework (CARF), a global standard for tax transparency in digital asset markets.
Affected firms must collect and report user information—including names, addresses, residency status, wallet details, and transaction histories—for tax residents in the UK and other CARF-participating jurisdictions. The move signals tightening regulatory oversight as governments worldwide seek to curb tax evasion in crypto markets.
