UK Tax Authority Mandates Domestic Crypto Reporting from 2026
UK crypto service providers face sweeping new reporting requirements starting January 1, 2026. His Majesty’s Revenue and Customs (HMRC) will require full transaction data disclosure for all UK-resident customers—a move extending OECD’s Cryptoasset Reporting Framework (CARF) to domestic operations.
The measure targets tax evasion vulnerabilities in digital asset markets. Unlike CARF’s cross-border focus, this domestic mandate ensures HMRC receives standardized data from all UK-based platforms—whether trading Bitcoin, Ethereum, or emerging tokens.
Regulators globally are tightening crypto oversight. The UK’s unilateral action precedes anticipated G20 coordination on asset reporting, reflecting urgency as decentralized finance protocols complicate tax enforcement.
