French Senate adopts bill for automatic sharing of crypto tax data

The French Senate adopted a bill on October 27, 2026, allowing tax authorities to automatically share cryptocurrency transaction data with international counterparts. Aligned with the OECD's Crypto-Asset Reporting Framework, Bill 3421 now moves to the National Assembly. While intended to enhance international tax compliance without adding new taxes, industry figures warn that centralized EU tax data repositories present severe safety and privacy risks, particularly in France where 33 of 52 global physical wrench attacks occurred in early 2026.
