The "Cryptocurrency Asset Reporting Framework" will be implemented in 2027, with 48 countries launching crypto tax data collection efforts this year.

On January 2, 2027, the OECD’s Cryptocurrency Asset Reporting Framework (CARF) will officially go into effect. Before that, starting January 1, 2026, the first group of 48 countries has required local crypto service providers to begin collecting users’ crypto wallet and transaction data to prepare for future international tax information sharing. Per the OECD, organizations taking part in data collection include centralized exchanges, some decentralized platforms, crypto ATMs, and brokers. CARF’s core goal is to boost tax transparency, fight cross-border tax evasion and money laundering, and make sure taxpayers meet their tax obligations regardless of where they trade crypto. Along with the initial 48 countries, 27 more jurisdictions (including Australia, Canada, Switzerland, and others) will start collecting data in 2027 and join the information sharing system in 2028. While CARF is officially intended for tax purposes, industry insiders note that the collected data could later be used for identity verification, anti-money laundering (AML) efforts, and criminal investigations—deeply affecting the crypto industry’s anonymity and regulatory landscape.
