France’s long-awaited electronic invoicing reform reaches a critical milestone on 1 September 2026, bringing one of Europe’s largest economies into a new era of digital VAT compliance.
From that date, large companies and mid-sized companies must issue electronic invoices, while all companies within the scope of the reform must be capable of receiving them.
SMEs and micro-enterprises have an additional year before their obligation to issue e-invoices and perform e-reporting begins on 1 September 2027.
The reform fundamentally changes how French businesses exchange invoices and how transaction information reaches the tax administration.
What Changes on 1 September 2026?
The French reform introduces electronic invoicing progressively according to company size.
From 1 September 2026
Large companies and mid-sized companies must issue electronic invoices.
At the same time, all companies covered by the reform — regardless of size — must be able to receive electronic invoices.
From 1 September 2027
Small and medium-sized enterprises and micro-enterprises become subject to the obligation to issue electronic invoices.
The same timetable applies to the introduction of e-reporting, under which relevant transaction information must be transmitted to the French tax administration.
This means the 2026 deadline is relevant even for businesses that do not have to start issuing electronic invoices until 2027. They still need to be ready to receive them from September 2026.
Who Is Covered?
The electronic invoicing requirement principally concerns transactions between businesses established in France and subject to VAT.
The scope includes:
- supplies of goods and services located in France between taxable persons where the transaction is not VAT-exempt;
- advance payments relating to these transactions; and
- certain public-auction transactions involving second-hand goods, works of art, collectors’ items or antiques.
Transactions falling outside the domestic B2B e-invoicing framework may instead become relevant for e-reporting, depending on the circumstances.
Businesses Need an Approved Platform
One of the most important operational aspects of the reform is the way invoices will move between businesses.
Companies will have to use a government-approved platform, either directly or through a compatible solution, for issuing and receiving electronic invoices and transmitting relevant data.
Businesses therefore need to determine how their existing ERP, accounting and invoicing systems will connect with the French e-invoicing ecosystem.
New Mandatory Invoice Information
The reform is not only about changing the format and transmission channel of invoices.
Additional information becomes mandatory on invoices in line with the phased implementation timetable.
This includes:
- the customer’s SIREN number;
- the delivery address where it differs from the billing address;
- information identifying whether the invoice relates exclusively to supplies of goods, services, or both; and
- an indication where the supplier has opted for VAT payment on debits.
Businesses therefore need to consider not only whether their systems can transmit an electronic invoice, but also whether their underlying master data contains the information required to populate it correctly.
E-Invoicing and E-Reporting Go Together
France’s reform extends beyond domestic electronic invoicing.
The implementation timetable also applies to e-reporting, which is designed to transmit transaction information to the tax administration for transactions falling within the relevant reporting scope.
This makes the project significantly broader than simply replacing PDF invoices with structured electronic documents.
Companies may need to map different transaction flows, determine whether each falls under e-invoicing or e-reporting, identify the required data and ensure that information can move correctly between operational systems, invoicing solutions and approved platforms.
Electronic Invoice Retention
Electronic invoices also bring specific integrity and retention considerations.
A qualified electronic seal may be used to help guarantee the authenticity of origin, integrity of content and legibility of electronic invoices.
Invoices created or received electronically must also be retained electronically for six years from the date on which the invoice was drawn up.
Overseas Territories: Different Treatment
The territorial scope also requires attention.
Businesses established in Guadeloupe, Martinique and Réunion are covered because VAT applies in these territories.
By contrast, several other French territories are outside the electronic invoicing requirement, including Guyana, Mayotte, Saint-Pierre-et-Miquelon, Saint-Barthélemy, Saint-Martin, New Caledonia, French Polynesia and Wallis and Futuna.
Why Is France Introducing the Reform?
France’s electronic invoicing programme is part of a much broader transformation of VAT administration.
The reform has several objectives: strengthening the fight against VAT fraud, reducing administrative burdens and payment delays through digitalisation, enabling greater simplification of VAT reporting — potentially including pre-filled VAT returns — and improving the administration’s visibility over economic activity.
The direction is therefore clear: VAT compliance is moving increasingly from periodic reporting toward transaction-level digital data exchange.
What Should Businesses Be Doing Now?
With the first major deadline effectively here, preparation should no longer be treated simply as a tax department project.
Businesses should have clarity over their transaction flows, entity populations, applicable e-invoicing and e-reporting requirements, approved platform arrangements, ERP connectivity, invoice master data and internal responsibilities.
Testing is particularly important. A business may technically have selected its platform while still encountering problems with customer identifiers, tax determination, invoice data quality or interfaces between systems.
For SMEs and micro-enterprises, the September 2027 issuance deadline may appear more distant. However, their obligation to receive electronic invoices starts on 1 September 2026, making readiness relevant now.
The Bigger Picture
France is one of several European jurisdictions moving toward mandatory structured electronic invoicing and increasingly digital VAT reporting.
For multinational groups, the challenge is therefore becoming less about implementing an isolated French solution and more about developing an architecture capable of supporting multiple national e-invoicing and digital reporting regimes.
France’s September 2026 milestone is another important step in that transition.
E-invoicing is no longer coming to France. It is happening.
