The trading data you have may go international next year.

According to the framework arrangement of the Organization for Economic Co-operation and Development (OECD), a system called the CARF (Crypto Asset Reporting Framework) is being promoted worldwide. This is not a rumor, but a confirmed policy milestone.

Here's the specific timeline:

**Starting January 1, 2026**, the first 48 jurisdictions will officially begin data collection—including the UK, EU countries, the Cayman Islands, Brazil, and others. This means that exchanges registered in these locations will start systematically organizing your tax identity and transaction records.

**In 2027**, the first formal cross-border data exchange will occur. At that time, these regions will activate automatic information sharing mechanisms. If your tax residence is China, entities registered with exchanges in the Cayman Islands or other participating regions will report your transaction data for the entire year of 2026 to the local tax authorities, which will then transmit the data directly to China's tax department through this automatic exchange system.

In other words, your activities on international exchanges will gradually be incorporated into the tax supervision framework through official channels. This will become the new normal for global crypto users. It's still not too late to consider your compliance strategy.
