CoinVoice has learned that starting this year, 48 countries and regions worldwide will begin recording cryptocurrency wallet transaction data to comply with the Crypto Asset Reporting Framework (CARF) officially implemented in 2027. Under the international tax transparency framework established by the Organisation for Economic Co-operation and Development (OECD), crypto service providers in participating jurisdictions—including centralized exchanges, some decentralized exchanges, crypto ATMs, and brokers—have been asked to start collecting the necessary transaction data. Additionally, a second group of 27 jurisdictions, including Hong Kong, Australia, Canada, Mexico, and Switzerland, will begin data collection on January 1, 2027, with information sharing starting in 2028. The framework aims to combat cross-border tax evasion and money laundering, and to increase transparency in crypto asset holdings.
