New Crypto Reporting Rules Reshape User Privacy

The EU's DAC8 and the OECD's CARF took effect on January 1, 2026, requiring regulated crypto exchanges to send users' personal data, transaction volumes, and wallet addresses directly to tax authorities. Platforms must track user data through 2026, with the first automated international data exchanges due by September 30, 2027. The rules end pseudonymous trading on mainstream platforms.
