PANews January 6 News, according to NADA NEWS reports, Japan officially adopted the OECD-issued Crypto-Asset Reporting Framework (CARF) starting January 1, 2026. This is a new mechanism designed to enable tax authorities worldwide to share information on crypto-asset transactions. Japan decided to introduce this mechanism through tax reform, and the National Tax Agency published a user-facing promotional manual before its implementation in December last year, while also advancing preparations to collect information through exchanges.
Affected by this system's implementation, Japan's crypto exchange Coincheck sent a notification to all users on January 6, requesting them to submit information such as "tax residence country." Other Japanese exchanges will also gradually implement information collection procedures. Existing users who have opened accounts by the end of 2025 are required to submit their information by December 31, 2026. Users who open new accounts after January 1, 2026, will need to provide their information during the account opening process.
