France Sets September 2026 Deadline for Receiving Electronic Invoices, 2027 for Issuing Them

From 1 September 2026, French organisations must be able to receive invoices through accredited electronic invoicing platforms. For entities dealing with the social‑security fund Atlas, invoices must include the identifier 851296632 and the Atlas dossier number in the “order‑reference” field. Until 31 August 2026 the documents are uploaded to the myAtlas Prestataire portal; from 1 September 2026 they must be transmitted via the electronic platform, while the Atlas API CFA remains unchanged.

The broader reform, phased by company size, obliges all businesses – including micro‑entrepreneurs and independent workers subject to VAT – to issue structured e‑invoices from 1 September 2027. The move aims to curb VAT fraud, streamline tax data reporting and harmonise France’s invoicing practice with the EU digital‑tax agenda.
