Japan to Implement OECD Crypto-Asset Reporting Framework Starting January 1, 2026

PANews, January 6 – According to NADA NEWS, Japan has officially adopted the Crypto-Asset Reporting Framework (CARF) issued by the Organisation for Economic Co-operation and Development (OECD) starting from January 1, 2026. This is a new mechanism aimed at enabling tax authorities around the world to share information on crypto asset transactions. Japan decided to introduce this mechanism through tax reform, and the National Tax Agency published a user guide prior to its implementation in December last year, while also preparing to collect information through exchanges.

As a result of the implementation of this system, a Japanese exchange sent a notice to all users on January 6, requiring them to submit information such as their “tax residency country.” Other Japanese exchanges will also gradually proceed with the information collection process. Existing users who opened accounts before the end of 2025 must submit the required information by December 31, 2026, while new users opening accounts after January 1 of this year must complete the declaration during the account opening process. Failure to submit the above information within the specified period, or submitting false information, may result in penalties in accordance with the law.
