From January 2026, exchanges will report all transaction details directly to HMRC under the Crypto-Asset Reporting Framework (CARF). Will this change how I calculate capital gains or income? What if I've mainly used non-UK or decentralised platforms – do I still need to self-report everything?
Happy New Year everyone! With the Crypto asset Reporting Framework (CARF) kicking in from 1 January 2026, UK-based (or UK-serving) exchanges are now collecting and reporting user data to HMRC. Can anyone clarify exactly what gets reported? Is it just personal info (name, address, NI number) plus transaction history, or also wallet addresses, balances, and every transfer (even to personal wallets)? I'm a UK resident using a mix of UK and international platforms – do foreign exchanges have to comply if they have UK users? Trying to make sure my records are spot-on before any data gets shared. Thanks!
