On the first business day of 2026, Japan officially launched the OECD's Crypto Asset Reporting Framework (CARF), a new mechanism with a straightforward goal — enabling tax authorities in different countries to share information related to crypto asset transactions.
This was not a decision made overnight. Japan had already decided to introduce this framework through tax reform last year. The National Tax Agency released a detailed promotional manual to users in December before the official implementation and collaborated with exchanges to complete the information collection preparations.
Now, it’s time for the implementation phase. Japan’s crypto exchanges, led by Coincheck, began sending notifications to users on January 6, requesting them to upload information such as "Tax Residency Country." Other exchanges will follow suit with similar procedures.
The rules are clear: users with accounts as of the end of 2025 must complete their information submission by December 31, 2026; new users must complete the declaration directly when opening an account. What if they fail to submit on time or provide false information? They will face penalties according to relevant laws. In other words, this is not just a notification but a strict requirement.

It's a game-changer, Japan's move has completely transformed the global tax game...
---
Here we go again, exchanges are asking us to submit all kinds of information, so annoying...
---
The CARF framework is basically about making us all transparent, haha
---
Japan is leading the way, other countries will definitely follow suit. The era of tax evasion is really coming to an end.
---
They pulled this move on the first day of 2026. It feels like a trap for retail investors...
---
So what exactly do we need to submit? The concept of "tax residence" still needs some thought.
---
Coincheck has already started urging? I need to check the notification quickly, don’t want to get fined.
---
Will falsifying information lead to penalties? Then everyone has to honestly fill in their real info, no room for maneuver.
---
Honestly, this framework is unfavorable for small investors; big institutions have already complied.

Before December 31, 2026... there's still time, but this seems pretty urgent.

Japan's move this time is really unstoppable. As soon as the CARF framework was implemented, they started cracking down, and it feels like they won't be able to hide it anymore in the future.

Can't escape now, Japan is really serious this time... They started laying the groundwork in December, and now they're going all out. Once the OECD framework is activated, it will be shared globally. I'm afraid our account information will be turned upside down.
