The OECD's Crypto-Asset Reporting Framework (CARF) is now active in 48 countries, requiring crypto service providers to report user transaction data to tax authorities. This initiative aims to enhance tax transparency and reduce tax evasion by facilitating automatic information sharing among jurisdictions starting in 2027.

Starting January 1, 2026, UK trading platforms must collect personal details from cryptocurrency traders, including transaction data and tax numbers, to enhance compliance with capital gains tax. Fines will be imposed on both traders and exchanges for non-compliance, potentially leading users to seek noncompliant platforms. The government expects to raise £315 million in tax revenue by April 2030.
