According to reports, the UK tax authorities have announced that, starting from January 1, 2026, cryptocurrency companies operating in the UK will be required to comprehensively report user and transaction data, in compliance with the global Crypto Asset Reporting Framework (CARF). This move aims to combat tax evasion and enhance transparency. Platforms must record user identity, address, tax identification number, and details of each transaction, including those involving users in the UK or other CARF countries. Foreign companies serving UK clients will also need to comply, and violators will face fines of up to £300 per user.
