France's structured e-invoicing mandate starts, and every business must now be able to receive

From 1 September 2026 every business established in France must be able to receive structured electronic invoices through an accredited platform. Large and mid-sized companies must also issue them and file e-reporting data from the same date. What changed The receiving obligation applies to all French-established businesses immediately, routed through a registered Plateforme Agréée sitting between trading partners. Issuing and e-reporting obligations start now for large and mid-sized companies; SMEs have until 1 September 2027 to begin issuing, though they must already receive. Company size was fixed by each business's position on 1 January 2025, so later growth does not move a company into a later window. Only Factur-X, UBL 2.1 and CII are accepted — an ordinary PDF does not satisfy the mandate. Foreign companies with no French establishment fall outside the e-invoicing duty, but e-reporting can still apply where they owe French VAT, and must go through an accredited platform; intra-EU supplies and exports are excluded. Structurally, the invoice becomes a validated document with a lifecycle — issued, received, rejected, accepted, paid — that both parties are expected to reflect in their own systems, with legal identifiers, unit codes and per-line tax categories becoming mandatory typed fields rather than free text. French authorities have signalled tolerance on penalties early on, but reporting suggests that tolerance is aimed at businesses that can show serious preparation; the per-transmission penalty structure, with an annual cap, remains.
