A coordinated effort to gather crypto tax records has begun in a group of jurisdictions preparing to take part in the Crypto-Asset Reporting Framework (CARF). According to official monitoring from the Organization for Economic Co-operation and Development (OECD) , 48 jurisdictions committed to start collecting standardized crypto transaction and user data from January 1, 2026, with the first automatic cross-border exchanges expected to take place in 2027. Countries Begin Collecting Data Based on reports , service providers such as major exchanges, some broker platforms, crypto ATMs and certain custody services will be obliged to record account details, transaction histories and users’ tax residency information for reporting to domestic tax authorities. That information will be formatted so it can be shared automatically with partner tax offices once the exchange phase starts. The OECD monitoring update lays out the kinds of fields that must be gathered and stored for future reporting. What Exchanges Must Report According to news outlets tracking the rollout, exchanges are already adjusting onboarding forms and internal compliance systems to verify customers’ tax residency and capture wallet-level activity. Some jurisdictions, led by the United Kingdom, have moved faster to require platforms to keep detailed purchase and sale records for users in scope. Tax authorities will then receive yearly reports covering balances, transfers and gains for listed accounts. Operational Strain And Privacy Questions The new rules create practical burdens. Smaller platforms will need to upgrade systems or hire compliance staff to track the new data points. Based on reports, privacy advocates and parts of the crypto industry are warning that the depth of data collection could raise concerns about how long sensitive transaction records are held and who can access them. Some legal teams are already studying how domestic data-privacy laws interact with automatic information exchange. Middle Nations Join The Second Wave A further group of jurisdictions has said it will begin domestic collection later. Reports note that an additional 27 jurisdictions have timelines that target January 1, 2027 for starting to collect, with exchanges of information to follow in 2028 for that batch. At least one analysis of national updates also indicates that a handful of countries are planning to stagger implementation because of local legislative calendars. How This Will Play Out For Users For ordinary crypto users, the immediate change will be more questions during account setup and clearer record-keeping demands from providers. Based on official guidance, CARF itself does not create new taxes; rather, it gives tax offices the data they need to enforce existing rules. For some investors, that means past reporting gaps will be easier for authorities to spot. Reports have disclosed that implementation will vary by country. Some tax administrations are ready to receive standardized files in 2027, while others are still finishing domestic law changes. Observers say the rollout marks a major step toward treating crypto transactions like other financial accounts when it comes to cross-border tax transparency.
