Electronic invoice 2026: obligations and deadlines

Updated March 2026 - The 2026 electronic invoice marks a major turning point for all companies domiciled in France. This reform gradually replaces paper invoices and PDFs with structured formats (Factur-X, UBL, CII) transmitted via approved dematerialization platforms.

As of September 1, 2026, all businesses must be able to receive electronic invoices. Large companies and ETIs must also issue them on this same date. SMEs and micro-enterprises will have until September 1, 2027** for the émission obligation. At the same time, e-reporting applies to transactions with individuals and cross-border operations.

The timetable has been confirmed by the government and the AIFE (State Financial Informatics Agency). It is broken down into two stages of entry into force:

September 1, 2026: reception obligatory for all#

On this date, all companies subject to VAT in France must be technically capable of receiving electronic invoices in the required formats. This receipt obligation is not subject to any postponement: it concerns both SASU and the CAC 40 group.

Simultaneously, large companies (more than 5,000 employees or turnover greater than 1.5 billion euros) and mid-sized companies (ETI) (250 to 4,999 employees or turnover between 50 million and 1.5 billion euros) must start to issue electronic invoices to their professional customers.

September 1, 2027: broadcast for SMEs and micro-enterprises#

SMEs (less than 250 employees, turnover or balance sheet total less than 50 million euros) and micro-enterprises have an additional period of one year. They must be able to issue electronic invoices on this date.

Point of vigilance: a company which crosses a threshold between 2026 and 2027 may see its calendar modified. It is prudent to prepare according to the earliest deadline.

Reform does not accept just any format. Three structured formats are officially recognized:

• Factur-X (hybrid PDF/XML, NF Z1-30 standard): the most widely used format in France, readable with the naked eye and automatically processed
• UBL 2.1 (Universal Business Language): international standard, particularly used in the Nordic countries
• CII (Cross Industry Invoice, UN/CEFACT standard): format also used at European level

Simple PDF, Word or scanned images are not compliant. An electronic invoice must contain structured data that can be used by a computer system without manual re-entry.

e-reporting is the obligation to transmit certain transaction data to the tax administration, separate from the electronic invoice itself. It concerns two catégories of flows:

Transactions with individuals (B2C)#

Companies must transmit data on payments collected from non-taxable persons. Concretely: if you sell to an individual, you do not issue an electronic invoice (no invoice obligation in B2C), but you must report the payment data.

Cross-border operations#

Transactions with foreign customers or suppliers (intra-community or outside the EU) are subject to e-reporting. The invoice itself can remain in the format agreed between the parties, but the data must be transmitted to the French administration via a partner dematerialization platform (PDP) or the public invoicing portal (PPF).

To delve deeper into the distinction between these two mechanisms, see our article on e-reporting and e-invoicing.

The State provides a public invoicing portal (PPF), free of charge, accessible on impôts.gouv.fr. This portal allows you to:

• Receive electronic invoices without going through a private platform
• Issue electronic invoices, particularly for VSEs and micro-enterprises
• Consult the history of invoices received and issued
• Perform e-reporting transmissions

The PPF is an entry-level solution. Businesses with an existing ERP or invoicing software will likely need to go through a private Partner Dematerialization Platform (PDP), which will interface with their systems.

To find out more about how the PPF works, consult our article dedicated to the public billing portal.

The 2026 electronic invoice is not a simple recommendation. Breaches can result in:

• Rejection of VAT deduction on non-compliant invoices received
• Loss of accounting proof in the event of a tax audit
• Financial sanctions: fine of 15 euros per non-compliant invoice (capped at 7,500 euros or 50% of the invoiced turnover)
• 5% increase in the event of omission or inaccuracy in e-reporting transmissions

These sanctions are initially progressive: the administration has announced a period of tolerance during the first months following each deadline. But this kindness does not exempt you from serious preparation.

Compliance is not limited to installing software. Here are the steps we recommend to our clients:

1. Map your billing flows#

List all of your incoming (supplier invoices) and outgoing (customer invoices) flows. Identify monthly volume, current formats and recipients. This mapping is the starting point for any compliance project.

2. Identify special cases#

Certain operations deserve specific attention:

• Invoices in foreign currencies
• Operations with VAT reverse charge
• Fee notes, credit notes and corrective invoices
• Regulated sectors (health, construction with retention of guarantee)

3. Choose your technical solution#

Two options are available to you:

• The public invoicing portal (PPF): free, suitable for small volumes
• A partner dematerialization platform (PDP): paid, but integrated into your ERP and offering advanced functionalities (validation workflow, archiving, automatic reconciliation)

4. Train your teams#

The electronic invoice changes work habits. Accounting teams, buyers and salespeople must understand the new process: reception, validation, processing of rejections and archiving.

5. Test before deadline#

PDPs provide testing environments. We strongly recommend carrying out end-to-end tests with a few willing suppliers and customers several months before the deadline.

To understand the opportunities that this reform represents beyond the constraint, read our analysis on the e-bill: a constraint, but also an opportunity.

The electronic invoice 2026 is no longer a distant project. With the deadline of September 1, 2026 for mandatory receipt and issuance of large companies, the countdown is underway. SMEs and micro-enterprises have an additional year, but technical and organizational preparations take several months.

Companies that anticipate this reform will take advantage of it to modernize their processes, reduce data entry errors and speed up their payment times. Those who wait until the last minute risk operational disruptions and financial penalties.

Hayot Expertise Advice: in 2026, the electronic invoice must no longer be treated as a "later" project. The right reflex is to identify your real flows and your specific cases before choosing your tools.
