48 countries including UK formally implement CARF crypto tax rules
Forty-eight countries, including the United Kingdom, have formally implemented a new crypto tax regulatory system, the Crypto-Asset Reporting Framework (CARF), from Jan. 1, 2026. Developed under the OECD, CARF is a global tax information standard aimed at preventing tax evasion using crypto and digital assets. In the UK, major exchanges must report users’ transactions and related details to HM Revenue and Customs, with wider automatic sharing from 2027.
