Starting January 2026, HMRC’s new rules require UK crypto exchanges to record and report detailed customer transactions, aligning taxation oversight with global OECD CARF standards.
HMRC will require UK cryptocurrency exchanges, designated as Reporting Cryptoasset Service Providers, to collect full transaction records from all UK customers starting January 1, 2026. Platforms must retain this information and submit it to HMRC by 2027, enabling cross-checking against tax returns. Sanctions will be imposed on non-compliant exchanges. The regulation aligns with the OECD’s Crypto-Asset Reporting Framework, harmonizing UK tax oversight with jurisdictions including the EU, Canada, Australia, Japan, and South Korea.
