France’s 2026 E-Invoicing Archiving Requirements

• France’s 2026 e-invoicing reform will require strict invoice archiving to ensure authenticity, integrity, and readability.
• Retention periods are at least 6 years for tax purposes and 10 years for accounting, and records must remain unchanged and accessible throughout.
• The archived set must include the exchanged invoice version, structured invoices (Factur-X, UBL, CII), related documents (POs, delivery notes, payment proof), and audit trail evidence.
• Archiving is more than storage: a compliant electronic archiving system (SAE), certified under NF Z42-013 / NF461, is needed for legal proof, traceability, and long-term preservation.
• Companies stay responsible for compliance even when using platforms, and invoices may only be destroyed after retention periods through documented, irreversible processes.
