UK Mandates Crypto Exchanges to Report Customer Transactions Starting 2026

According to ChainCatcher, the UK tax authority, HM Revenue and Customs (HMRC), has announced new regulations requiring cryptocurrency exchanges operating in the UK to collect comprehensive transaction records of all their UK customers starting January 1, 2026. These records must be shared with HMRC the following year. The collected data will be used to verify tax returns, ensure compliance, and penalize any violations. The new guidelines align the UK with the OECD's Crypto-Asset Reporting Framework (CARF), which aims to enhance transparency in the rapidly growing digital asset market. This framework is already being implemented in regions such as the European Union, Canada, Australia, Japan, and South Korea.
