UK to Mandate Domestic Crypto Reporting by 2026: Expanding Tax Authority Access

Starting in 2026, the UK will require crypto platforms operating within its borders to submit detailed reports on all transactions made by domestic users. This expansion of the Cryptoasset Reporting Framework (CARF) provides tax authorities with automatic access to both domestic and international transaction data for the first time. This move closes a reporting gap previously limited to cross-border activity, strengthening oversight before global exchange of information under CARF begins in 2027.
