UK Tightens Crypto Reporting, Expanding CARF to Domestic Users

The UK government is strengthening its crypto oversight with expanded reporting requirements for domestic users beginning in 2026. These changes form part of the Cryptoasset Reporting Framework (CARF) and allow UK tax authority HMRC access to domestic and international transaction data for the first time. This move addresses a gap left by CARF’s initial focus on cross-border activity, ensuring crypto remains under regulatory scrutiny.
