Mandatory E-Invoicing in France from September 2026: What Businesses Need to Know

/in /by

France is moving forward with a major digital transformation of its invoicing and tax reporting framework. Beginning on 1 September 2026, electronic invoicing and e-reporting requirements will be introduced in phases, affecting how businesses issue, receive, and report invoice-related data to the French tax authorities.

For companies operating in France, this reform goes far beyond a simple compliance update. It requires organizations to review their invoicing workflows, accounting procedures, ERP systems, POS platforms, and financial reporting processes to ensure they are ready for the new obligations.

What Will Change?

The reform introduces two complementary requirements:

  • E-invoicing, which applies to qualifying business-to-business (B2B) transactions.
  • E-reporting, which covers transactions that fall outside the mandatory e-invoicing scope.

The objective is to improve VAT transparency, streamline tax administration, and enhance the accuracy of transaction reporting through digital processes.

Businesses subject to French VAT rules will generally be affected. From September 2026, all impacted companies must be capable of receiving electronic invoices, while the obligation to issue them will be implemented progressively according to company size.

International groups should pay particular attention to these changes. Even when accounting systems or ERP governance are managed outside France, French subsidiaries and entities may still be required to comply with the French framework.

Implementation Timeline

The French government has established a phased rollout schedule:

From 1 September 2026

  • All affected businesses must be able to receive electronic invoices.
  • Large companies and intermediate-sized enterprises must issue electronic invoices.
  • E-reporting obligations begin for large and medium-sized businesses.

From 1 September 2027

  • SMEs and micro-enterprises must begin issuing electronic invoices.
  • E-reporting obligations extend to smaller businesses and sole proprietors.

Companies should incorporate these deadlines into their compliance and digital transformation strategies well in advance.

Company Size Determines the Deadline

The applicable implementation date depends on the size of the business.

Micro-enterprises

  • Fewer than 10 employees.
  • Annual turnover or balance sheet total not exceeding €2 million.
  • Required to receive electronic invoices from September 2026.
  • Required to issue electronic invoices from September 2027.

Small and Medium-Sized Enterprises (SMEs)

  • Fewer than 250 employees.
  • Annual turnover up to €50 million or total assets up to €43 million.
  • Required to receive electronic invoices from September 2026.
  • Required to issue electronic invoices from September 2027.

Intermediate-Sized Enterprises (ETIs)

  • Larger than SMEs but below the threshold for large companies.
  • Required to receive and issue electronic invoices from September 2026.

Large Enterprises

  • 5,000 employees or more.
  • Annual turnover exceeding €1.5 billion and total assets above €2 billion.
  • Required to receive and issue electronic invoices from September 2026.

Even businesses that are not required to issue electronic invoices until 2027 must ensure they can receive them from September 2026.

E-Invoicing and E-Reporting: Understanding the Difference

Although often discussed together, e-invoicing and e-reporting serve different purposes.

E-Invoicing

E-invoicing applies to domestic B2B transactions between VAT-registered businesses established in France. Invoices must be generated in a structured electronic format and transmitted through an approved platform that also communicates the relevant data to the tax authorities.

E-Reporting

E-reporting applies to transactions that fall outside the mandatory e-invoicing framework, including:

  • Business-to-consumer (B2C) transactions.
  • Certain transactions involving non-VAT-registered entities.
  • Cross-border transactions with foreign businesses.
  • Specific payment-related information where VAT becomes due upon receipt of payment.

Together, these measures provide the French tax administration with greater visibility over commercial transactions and VAT flows.

Financial Penalties for Non-Compliance

Businesses that fail to comply with the new rules may face substantial financial penalties.

General invoicing breaches can lead to significant fines, with higher sanctions for repeated violations. Specific penalties related to electronic invoicing may also apply, including fines for missing electronic invoices, failure to use an approved invoicing platform, or failure to transmit required transaction and payment information.

These penalties highlight the importance of preparing well before the implementation deadlines.

How Businesses Can Prepare

Organizations should avoid viewing the reform as a simple software upgrade. Compliance will require a broader review of internal processes, data quality, and system integration.

Key actions include:

  • Identifying which legal entities are affected.
  • Determining the applicable company size category and compliance deadlines.
  • Assessing current invoicing, ERP, POS, and PMS systems.
  • Reviewing the quality and availability of invoicing and transaction data.
  • Planning integration with approved electronic invoicing platforms.
  • Preparing internal teams for new reporting and compliance requirements.

Early preparation will help businesses reduce implementation risks, avoid operational disruptions, and ensure full compliance with the upcoming French e-invoicing and e-reporting obligations.

With September 2026 approaching, companies should begin evaluating their readiness now to ensure a smooth transition to the new digital tax environment.
