Techub News reports that, according to the Financial Times, the UK and more than 40 other countries have implemented the OECD's "Crypto Asset Reporting Framework" (CARF) starting from January 1. The framework requires major crypto exchanges to collect complete transaction records for UK users and report user transaction details and tax residency status to Her Majesty's Revenue and Customs (HMRC). The report states that the UK is one of the first 48 countries to implement the framework. According to the plan, starting from 2027, HMRC will automatically share relevant data with EU member states, as well as Brazil, the Cayman Islands, South Africa, and other participating parties. A total of 75 countries have committed to implementing CARF. The United States plans to implement it in 2028 and begin information exchange in 2029.
