Key points

  • The French Senate passed a bill adopting the OECD's Crypto-Asset Reporting Framework, transmitting it to the National Assembly as Bill no. 3421.
  • The European Commission plans to establish a central repository for cross-border DAC8 crypto tax filings by the end of 2026.
  • CertiK data shows France accounted for 33 of 52 globally verified physical crypto thefts during the first half of 2026.

The French Senate passed a bill authorizing domestic tax authorities to automatically exchange cryptocurrency transaction data with international counterparts 1. The measure cleared its first reading and moved to the National Assembly as Bill no. 3421 for further consideration 1.

The legislation operationalizes an agreement structured around the Crypto-Asset Reporting Framework (CARF), an initiative established by the Organisation for Economic Co-operation and Development (OECD) 1. CARF establishes standardized requirements for participating nations to collect and exchange taxpayer transaction data across borders 1. France previously enacted related compliance rules under its 2025 Finance Act, transposing the European Union's DAC8 directive to mandate customer data collection by crypto service providers 1. Readers can review how CARF and EU DAC8, Explained: Global Automatic Crypto Tax Reporting details these shared reporting frameworks.

Security Pushback and Fiscal Debates

The Senate's move arrives amid parallel fiscal debates in France 1. Lawmakers are considering a 2027 budget amendment, approved by the National Assembly on Oct. 16, that would tax gains on trades into certain fiat-pegged stablecoins starting Jan. 1, 2027 1. Budget revenue debates resumed recently ahead of a Nov. 3 vote, though the measure is not yet enacted 1.

Industry representatives have warned about the personal risks tied to expanding fiscal databases 1. Under DAC8, reporting involves transmitting names, residential addresses, tax identifiers, and transaction amounts 1. The European Commission plans to launch a centralized repository for crypto tax filings by the end of 2026, granting access to tax authorities across EU member states 1. Faustine Fleuret, global head of public affairs at lending protocol Morpho, warned that centralizing such sensitive information establishes a single point of failure and escalates physical security threats for domestic investors 1.

Physical confrontations, colloquially referred to as wrench attacks, have risen significantly in the jurisdiction 1. Data from blockchain security company CertiK indicates that France accounted for 33 of 52 verified wrench attacks globally during the first half of 2026 1. In one March occurrence cited by the firm, criminals impersonating police officers stole approximately $1 million in $BTC from a French couple 1.
