Japan Adopts OECD Crypto Reporting Framework Starting January 1, 2026

According to ChainCatcher, market sources indicate that Japan has officially adopted the OECD's Crypto-Asset Reporting Framework (CARF) starting from January 1, 2026. This is a new mechanism designed to enable tax authorities around the world to share information on crypto-asset transactions. Japan decided to introduce this framework through tax system reforms. The National Tax Agency published a user guide for the public in December of last year, prior to implementation, and has been advancing preparations for collecting information through exchanges. Affected by this new regulation, Japanese crypto exchange Coincheck sent a notice to all users on January 6, requesting them to submit information such as their "Tax Residency Country." Other Japanese exchanges will also gradually proceed with information collection procedures. Existing users who opened accounts before the end of 2025 must submit the required information by December 31, 2026. Users who open new accounts on or after January 1, 2026, must complete the declaration as part of their account opening process. Failure to submit the required information within the specified timeframe or providing false information may result in legal penalties.
