According to DL News, based on a new regulation introduced by the UK tax authority, from January 1, 2026, cryptocurrency companies operating in the UK will be required to collect and report detailed user and transaction data. Crypto platforms must identify each user and record their legal identity information, address, and taxpayer identification number. Additionally, platforms must record every transaction involving UK users or users from other CARF participating countries, including transaction amount, asset type, quantity, and nature of the transfer. These requirements also apply to overseas companies providing services to UK customers. If the reported information is incorrect or incomplete, each user may be fined up to £300.
