The UK requires cryptocurrency exchanges to collect and report transaction records of UK customers starting from 2026

According to CoinDesk, the UK's HM Revenue and Customs (HMRC) has issued new regulations requiring cryptocurrency exchanges operating in the UK to begin collecting complete transaction records of all their UK customers starting January 1, 2026, and share them with HMRC the following year. HMRC will use the collected data to verify tax returns, ensure compliance, and impose penalties for violations.

The new guidelines from HMRC align the UK with the OECD's Crypto-Asset Reporting Framework (CARF), which aims to enhance the transparency of the rapidly growing digital asset market and is currently being promoted in countries and regions such as the EU, Canada, Australia, Japan, and South Korea.
