Breaking News: Japan will officially implement the international tax information sharing framework for crypto assets, CARF, on January 1, 2026. This framework, developed by OECD, is mainly aimed at preventing tax evasion related to cross-border crypto assets.

Attention all users who have opened accounts on Japan's mainstream exchange Coincheck: the exchange has issued a notice to all users requiring the declaration of key information such as "tax residence country." For users who have already opened accounts before the end of 2025, the relevant tax information must be declared by December 31, 2026.

What does this mean? In simple terms, if you have a crypto asset account in Japan, you need to clearly inform the exchange of your tax residence country. This is an important step in promoting transparent management of crypto assets worldwide. After the policy takes effect, government agencies in various countries will be able to more effectively track cross-border crypto asset flows and combat tax-related illegal activities.

Advice for ordinary users is clear: log into your account early and complete the tax information declaration according to the exchange's prompts. Don't wait until the end of 2026 to rush and handle it, as that could lead to various issues due to high demand. Additionally, if your tax situation is complex, it’s best to consult a professional tax advisor in advance.
