The transaction data in your hands may go cross-border next year.

Following the framework arrangement by the Organisation for Economic Co-operation and Development (OECD), a system called CARF (Crypto Asset Reporting Framework) is being promoted globally. This is not a rumor, but an already confirmed policy milestone.

Here's the specific timeline:

**Starting January 1, 2026**, the first batch of 48 jurisdictions will officially launch data collection——including the UK, EU countries, the Cayman Islands, Brazil and other regions. This means that exchange branches registered in these locations will begin systematically organizing your tax identity and transaction records.

**2027** is the first formal cross-border data exchange. At that time, these regions will activate an automatic information sharing mechanism. If your tax residence is China, exchange entities registered in the Cayman Islands or other participating jurisdictions will report your full-year 2026 transaction data to local tax authorities, and then local authorities will directly transmit it 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 regulatory framework through official channels. This is a new normal for all global crypto users. There's still time to consider your compliance layout now.
