Electronic invoicing timeline in France: 2026-2027 deadlines

The French electronic invoicing reform follows a national timeline set by the 2024 Finance Act and detailed by the DGFiP. After several postponements, two dates now structure the trajectory of every business: September 1, 2026 and September 1, 2027. This electronic invoicing timeline drives the choice of providers, budgets and internal project planning for nearly four million VAT-liable companies.

In brief:

1. On September 1, 2026, the reception obligation applies to every VAT-liable company, and issuance becomes mandatory for large enterprises and mid-cap businesses.
2. On September 1, 2027, the issuance obligation extends to SMEs, very small businesses and micro-entrepreneurs.
3. The 2024 Finance Act, article 91, confirmed these dates after the abandonment of the original July 2024 schedule.
4. A minimum twelve-month roadmap is recommended to select a certified platform, test flows and train teams.

Postponement history: from July 1, 2024 to September 1, 2026

The general rollout project of dematerialised invoicing dates back to ordinance 2021-1190 of September 15, 2021. Decree 2022-1299 of October 7, 2022 initially set a progressive entry into force from July 1, 2024, with pilot phases planned in the first half of the same year. Economic actors, software publishers and future certified dematerialisation partner platforms were expected to prepare within this window.

On July 28, 2023, the DGFiP announced a first postponement. The technical complexity of the Public Invoicing Portal, managed by the Agency for State Financial IT (AIFE), did not allow a controlled launch. Several months of consultation with professional organisations and software vendors led to a revised timeline, voted in the 2024 Finance Act and codified in article 91 of that law.

“The objective remains the rollout to the entire French economic fabric, in conditions of reliability and security that require an adjusted timeline.” – DGFiP communique, July 2023

The pilot phases originally programmed for 2024 were formally abandoned. The DGFiP chose a two-step switch around September 2026 and September 2027, more realistic for software publishers and businesses. To understand the full mechanism and the actors involved, the complete guide to electronic invoicing details the legal context, formats and beneficiaries.

September 1, 2026: the first mandatory milestone

On September 1, 2026, two obligations enter into force simultaneously. The first concerns reception: every business established in France and subject to VAT must be technically able to receive an invoice in the standard format via a dematerialisation platform. No exception is provided, not even for micro-entrepreneurs or structures that do not issue invoices themselves.

The second obligation concerns issuance. Large enterprises (over 5,000 employees or 1.5 billion euros in turnover) and mid-cap companies (250 to 5,000 employees, or 50 million to 1.5 billion euros in turnover) must issue all their domestic B2B invoices in Factur-X, UBL 2.1 or CII format compliant with the European EN 16931 standard. This issuance must go through a certified dematerialisation partner platform registered by the DGFiP, or via the Public Invoicing Portal.

This deadline applies to the e-invoicing obligation on the domestic business-to-business scope. B2C and B2G flows follow specific rules. B2G transactions via Chorus Pro, managed by AIFE, remain on their current trajectory (already mandatory since 2020 for the public sphere). B2C operations feed a parallel e-reporting flow, targeted by the anti-VAT-fraud effort and the continuous transactional control.

The compliance timeline therefore requires large enterprises and mid-cap companies to finalise their project before summer 2026, which implies having chosen their provider by late 2025 or early 2026. To understand precisely who is concerned by the obligation, a dedicated guide distinguishes the categories by company size.

September 1, 2027: rollout to SMEs and very small businesses

September 1, 2027 marks the full rollout of the issuance obligation. SMEs (less than 250 employees and less than 50 million euros in turnover), very small businesses and micro-entrepreneurs switch in turn to mandatory issuance. By this date, the entirety of the French B2B economic fabric is covered.

This deadline concerns the numerical majority of companies. According to INSEE data, France counts approximately 4.1 million VAT-liable businesses, of which more than 95% fall in the SME, very small business or micro-entrepreneur category. The schedule therefore grants these structures one additional year to finalise their tooling, processes and training compared with large enterprises.

The twelve-month gap between September 1, 2026 and September 1, 2027 has a practical logic. Accounting software publishers (Sage, Cegid, EBP, Pennylane, Indy, Tiime, Henrri, Axonaut) expect a peak in onboarding and support requests in the second half of 2026. SMEs and very small businesses relying on these solutions thus benefit from the lessons learned by large enterprises.

Micro-entrepreneurs and self-employed professionals, despite their VAT exemption, are concerned by the reform because they may issue invoices to VAT-liable businesses. Their specific situation is detailed in the dedicated article on reform and self-employed professionals.

Table of key milestones set by the DGFiP

The table below summarises the structuring dates of the dispositive. It is built from DGFiP communiques, the impots.gouv.fr portal and texts published on Legifrance.

To grasp the role of the DGFiP in electronic invoicing and understand how the tax administration articulates its dispositives (BOFIP, BOI-TVA-DECLA-30 base, continuous transactional control), a dedicated article goes deeper. Main institutional sources remain impots.gouv.fr and portailpro.gouv.fr, complemented by BOFIP bulletins and Legifrance texts.

Choice of dematerialisation platform: a milestone to plan early

The first internal milestone for a company is the choice of its certified dematerialisation partner platform. These platforms are private providers registered by the DGFiP, which handle invoice transmission, legal archiving and the transfer of fiscal data to the administration. The list of registered platforms is published on impots.gouv.fr and evolves with each new certification.

Platform certification by the DGFiP follows a demanding technical procedure. The candidate must demonstrate compliance with a series of interoperability tests with the Public Invoicing Portal, archival capacity meeting evidentiary standards, and respect of security requirements. Early certified providers include Docaposte, Generix, Yooz, Esker and several ERP vendors such as Sage, Cegid and Pennylane.

A company may alternatively rely on the free Public Invoicing Portal managed by AIFE. This option limits advanced features (approval workflow, ERP integration, multi-entity management) but suits simple structures with limited volume. The comparison between certified platforms and the public portal is detailed in the article on choosing a certified platform.

The delay between contract signature with a certified platform and effective production varies from eight weeks to six months depending on integration complexity. A company that must issue invoices on September 1, 2026 must therefore have selected its provider by February 2026 at the latest, ideally during autumn 2025 for multi-site organisations.

Internal roadmap: twelve months of preparation

The roadmap recommended by software publishers and consulting firms spans twelve months before the applicable deadline. This duration covers needs analysis, consultation, technical onboarding, testing, training and rollout. Organisations starting less than six months before the deadline expose themselves to a high risk of slippage.

The table below details the recommended steps for a company whose issuance deadline is September 1, 2027. For a deadline on September 1, 2026, the same scheme applies with each step shifted twelve months earlier.

The framing phase occupies the first quarter. It consists of mapping current invoicing flows (monthly volume, formats, channels), identifying ERPs, accounting software and home-grown systems that produce or consume invoices, and designating an executive-level project sponsor. Steering by the finance department or IT is generally most effective, in coordination with procurement.

The selection phase mobilises the finance, legal and IT teams. The choice of a platform rests on technical criteria (formats supported, volume capacity, ERP integration), commercial criteria (price per invoice or subscription, support) and governance criteria (data sovereignty, archiving in France). ERP publishers often integrate their own platform subsidiary, which can simplify deployment. The comparison of electronic invoicing software details market options.

Risks of delay: financial penalties and operational blockages

A company unable to receive an invoice on September 1, 2026 or to issue one on the applicable deadline faces two types of consequences. The first is financial: the French tax code, article 1737, sets a fine of 15 euros per non-compliant invoice, capped at 15,000 euros per calendar year. A company issuing several hundred invoices per month quickly reaches this ceiling.

The second consequence is operational. A supplier whose client cannot receive a compliant electronic invoice ends up at risk. It may be forced to suspend invoicing, postpone revenue recognition, or resort to manual follow-ups. At the scale of the procurement chain, these breakdowns generate longer payment delays and commercial disputes.

AIFE and the DGFiP have announced that no generalised tolerance is planned. The first months of implementation may receive a degree of leniency in audits, but regulatory penalties remain applicable from day one. BOFIP bulletins specify that failure to use the standard format equates to non-compliance under article 289 of the French tax code.

The transmission of invoicing data to the DGFiP is integrated into the dispositive. Each electronic invoice feeds a fiscal database used by the administration for audits and VAT pre-filling. This transmission strengthens continuous transactional control and the fight against VAT fraud, in line with the Italian (FatturaPA) and Spanish (SII) models.

Planning advice: avoiding common pitfalls

Three pitfalls are frequently mentioned in feedback from Italian and Spanish companies, which switched in 2019 and 2017 respectively. The first is to underestimate the cleanup of customer and supplier data. The standard format (Factur-X, UBL 2.1, CII) requires a valid SIRET identifier, correct VAT details and consistent business references. A dirty supplier base generates cascading rejections.

The second pitfall is to treat the project as a purely IT matter. Electronic invoicing modifies accounting, procurement and sales processes. Change management matters as much as technical onboarding. Insufficient training of operational teams leads to data entry errors, disputes and degraded platform usage.

The third pitfall concerns ecosystem alignment. A company is compliant only if it can exchange with its partners. If its main supplier has not yet selected a platform at the time of the switch, flows do not pass. Anticipating communication with key partners, even supporting them, is decisive. Professional organisations (CPME, MEDEF, U2P) have published sectoral guides.

The electronic invoicing timeline still evolves at the margin according to DGFiP communiques. Companies must monitor official publications on impots.gouv.fr and portailpro.gouv.fr, as well as BOFIP bulletins. Monthly monitoring, run by the finance department or an accounting firm, helps anticipate adjustments.
