UK Enforces OECD CARF Crypto Reporting From January 1, 2026, Targeting Tax Evasion

On January 1, 2026, the UK began enforcing the OECD’s Cryptoasset Reporting Framework, compelling crypto platforms to submit detailed user data directly to HMRC. Reports covering 2026 activity are due by May 31, 2027, and from 2027 HMRC will share data with other CARF jurisdictions. Non-compliance risks include penalties up to £300 per user, back taxes, and further investigations.
