Online reports, according to DL News, starting from January 1, 2026, crypto asset companies operating in the UK will be required to collect and report detailed user and transaction data in accordance with a new rule introduced by the UK tax authority. The change stems from the UK's adoption of the Crypto Asset Reporting Framework (CARF), a global standard designed to combat tax evasion and align transparency in the crypto industry with that of the banking system. Under the new rules, encryption platforms must identify each user and record their legal identification information, address and taxpayer identification number. In addition, the platform also needs to record every transaction involving users in the UK or users in other CARF participating countries, including details such as transaction amount, asset type, quantity and nature of transfer. These requirements also apply to overseas companies providing services to UK customers. If the information reported is incorrect or incomplete, each user can be fined up to £ 300.
