France E-Invoicing September 2026: What Happens Next

The deadline you circled is no longer in the future. It passed on 1 September 2026, and the rules are now the working environment rather than the project plan. Most of what has been written about France's e-invoicing reform covers the run-up. This is what the reform looks like now that it is live.

What Changed on 1 September

Two obligations took effect on 1 September 2026. Every VAT-registered business in France, regardless of size, must be able to receive electronic invoices through an accredited platform. Large enterprises and mid-sized companies (ETIs) must begin issuing e-invoices and filing e-reports. SMEs and micro-enterprises have a further year before they must issue, until 1 September 2027.

The legal calendar was not suspended. Nothing in the guidance published over the summer pushed the start date back. What changed is how the tax authority plans to treat the businesses that are not ready.

Penalty Tolerance Is Not a Grace Period

On 11 July 2026 the DGFiP said it would not apply penalties automatically or immediately to taxpayers who miss the 1 September date. That line was quoted everywhere, and most of the time it was read as a soft launch. It is not. The authority will assess each taxpayer individually and expects credible, documented evidence of active compliance efforts from the start.

The distinction the DGFiP draws is between genuine difficulty and avoidance. A failed integration, a platform outage, a recipient it cannot find in the directory — those sit on the tolerated side if you are actively working through them. Inertia and refusal do not. If a taxpayer has made no effort, or cannot prove one, penalties can apply immediately.

The money at stake has risen. The 2026 Budget Law, adopted on 2 February 2026, raised e-invoicing penalties from €15 to €50 per invoice, capped at €15,000 per calendar year. E-reporting failures cost €500 per transmission, also capped at €15,000 a year.

What counts as evidence is specific: dated correspondence with your provider, records of the difficulty, and a visible trajectory toward compliance. The weeks ahead are about building that paper trail, not waiting for an extension that was never granted.

The Only Three-Month Window Is Narrow

There is a formal notice mechanism, the mise en demeure, and it is the thing people keep misquoting as a blanket grace period. It grants a three-month period to regularize, but only for one obligation: using an accredited platform to receive invoices.

If you are not compliant with receiving, the DGFiP issues a formal notice first, then you have three months to register before per-invoice fines kick in. That window does not cover issuance failures, and it does not cover e-reporting. It is not a general postponement.

For a business that still has not connected to a platform, the sequence matters. Register for receiving now, because that is the one obligation with a structured remedy.

What to Do About Invoices That Already Missed the Route

If technical problems meant you issued or received invoices by mail, PDF, or paper, you are expected to regularize them. Transmit those invoices through the accredited platform as soon as the difficulty is resolved.

The trap is double-processing. When you regularize, you must avoid paying twice, booking twice, or deducting VAT twice. A document pipeline that flags duplicates before they hit the books earns its keep here, which we cover in our duplicate invoice detection guide.

Document the circumstances of every invoice that went the old route. The DGFiP is watching the regularity of your cleanup, not the delay.

What the Simplification Measures Actually Remove

Not everything got stricter this year. The obligation to e-report international incoming invoices at line-item level has been removed, for purchases from both EU and non-EU suppliers. You also will not need to file blank e-reports when no taxable transaction occurred.

Non-established taxpayers have had their e-reporting obligations postponed to September 2027. That is a real load off foreign entities selling into France, though it is a reporting deferral, not an exemption from receiving or issuing.

The Accredited Platform Is Now the Only Door

The terminology changed quietly this summer, and it matters if you are still reading older guidance. Decree No. 2026-677 of 27 July replaced the PDP and PPF as separate concepts with a single figure, the plateforme agréée, or accredited platform (PA). The PPF no longer exchanges invoices itself. It routes them between accredited platforms as the Central Directory.

In practice, your invoice travels from your PA to your customer's PA, while your platform sends a regulatory data subset to the PPF. The format requirement is strict too: a compliant e-invoice is structured data, machine-readable information in a defined format that can be validated, transmitted, and reported automatically. A scanned PDF or an emailed invoice does not count.

Switching platforms is also no longer casual. The Budget Law introduced a one-year minimum service continuity requirement, so your former PA must keep services running for a year after you move.

What Finance Teams Need to Confirm Now

The day-one checklist is short and documentable. Confirm your PA connection is live and that you have completed an end-to-end receive test. Collect the customer SIREN number, the delivery address where it differs from billing, the transaction category, and the VAT-on-debits flag where applicable. These four fields became mandatory on 1 September 2026. A fuller target dataset arrives on 1 September 2027.

Make sure every invoice you touch is structured data in an accepted format, not a PDF pretending to be one. Keep those invoices in their original structured format for six years from the date they were drawn up.

This is where Zerentry fits. The platform extracts VAT, validates against French schemas, and syncs structured data to your accounting software, so the invoices you regularize and the ones you receive going forward arrive in a format the PA and the directory can read.
