On 26 October 2026, Luxembourg and France enacted parallel legislative frameworks to dramatically expand automatic exchange of financial and tax-relevant data targeting cross-border fraud schemes. The Luxembourg law, passed as an amendment to the General Tax Law (Loi générale de l’impôt), implements the EU’s DAC8 directive ahead of schedule and adds a bilateral protocol with France enabling real-time access to beneficial ownership registers, crypto-asset transaction logs, and e-invoicing data. The French counterpart, embedded in the 2027 Finance Bill, grants its tax administration (DGFiP) direct query rights into Luxembourg’s new centralized ultimate beneficial owner (UBO) database for entities with French economic ties. Both laws entered into force on 1 November 2026, with first data transfers scheduled for Q1 2027.
Key Takeaways
- Real-Time UBO & Crypto Data Exchange: Financial institutions and crypto-asset service providers (CASPs) in Luxembourg must now report beneficial ownership changes and all crypto transactions exceeding €1,000 to the ACD (Administration des Contributions Directes) within 24 hours, which are automatically shared with French authorities.
- E-Invoicing Interoperability Mandate: Starting 1 January 2027, B2B e-invoices issued between Luxembourg and French VAT-registered entities must flow through the Peppol network with mandatory transmission of invoice data to both tax administrations, enabling instant cross-border VAT fraud detection.
- Enhanced Penalties & Whistleblower Protections: Non-compliance fines reach 5% of annual turnover for repeated failures. Both laws introduce enhanced whistleblower protections and a joint Franco-Luxembourg investigation unit with powers to conduct coordinated dawn raids.
