What Is the 2026 Reform?
The 2026 reform is France’s sweeping mandate to digitize all business-to-business invoicing and implement comprehensive tax transaction reporting. Officially codified in the Finance Law (Loi de Finances), this reform makes it mandatory for all VAT-registered businesses in France to issue and receive electronic invoices through approved channels and to report certain transaction data (e-reporting) to the tax authorities.
Originally planned for 2024, the reform was postponed to allow businesses and the technical infrastructure more time to prepare. The definitive timeline now starts in September 2026, with a phased rollout based on company size.
The Reform Timeline
September 1, 2026
- Reception obligation: All businesses, regardless of size, must be able to receive electronic invoices through the PPF or a certified platform (PDP).
- Emission obligation for large companies: Large enterprises (grandes entreprises) and mid-sized companies (ETI, entreprises de taille intermediaire) must begin issuing electronic invoices.
- E-reporting begins: Large and mid-sized companies must start submitting e-reporting data for B2C and international transactions.
September 1, 2027
- Emission obligation for all: Small businesses (PME) and micro-enterprises (TPE) must begin issuing electronic invoices.
- Universal e-reporting: All businesses must comply with e-reporting obligations.
What the Reform Requires
For B2B Domestic Transactions
Every invoice exchanged between two French VAT-registered businesses must:
- Be in one of the three accepted formats: Factur-X, CII XML, or UBL.
- Contain all mandatory fields per the EN 16931 European standard and the French CIUS (Core Invoice Usage Specification).
- Include seller and buyer SIRET numbers, VAT identification, and all legally required mentions.
- Be transmitted through the PPF or a certified PDP.
For B2C and International Transactions (E-Reporting)
Transactions not covered by B2B e-invoicing still require periodic reporting:
- B2C sales data (aggregated by VAT rate).
- International transaction summaries.
- Payment data for certain transaction types.
Infrastructure Registration
Every business must:
- Register on the PPF directory.
- Declare its preferred invoicing channel (PPF direct or a specific PDP).
- Ensure its SIRET and identification data are up to date.
Why France Is Implementing This Reform
The reform is driven by several strategic objectives of the DGFiP:
- VAT gap reduction: France’s VAT gap is estimated at several billion euros annually. Real-time invoice data enables better fraud detection and compliance monitoring.
- Pre-filled VAT returns: Transaction data flowing through the PPF will allow the DGFiP to pre-fill VAT declarations, reducing errors and simplifying compliance.
- Economic modernization: Mandatory e-invoicing pushes businesses toward digital workflows, reducing processing costs and accelerating payment cycles.
- Competitiveness: Aligning with EU Directive 2014/55/EU and the broader European trend toward e-invoicing.
How to Prepare
Step 1: Assess Your Current Invoicing Process
Review how your business currently generates, sends, and receives invoices. Identify gaps between your current process and the reform requirements. Key questions:
- Are your invoices in a structured format or just PDF?
- Do your invoices include all required fields (SIRET, VAT details, legal mentions)?
- How do you handle B2C and international invoicing?
Step 2: Choose Your Platform
Decide whether to use the PPF directly or a certified PDP. Consider:
- The PPF is free but offers basic functionality.
- PDPs provide advanced features like format conversion, integrations, and automation.
- Your billing platform compatibility (e.g., does your PDP integrate with Stripe or Shopify?).
Step 3: Implement Compliance Tooling
For businesses using SaaS billing platforms, the most efficient approach is often to use a compliance layer that:
- Connects to your billing platform via API.
- Enriches invoices with required French data.
- Generates compliant Factur-X documents.
- Handles submission to the PPF or PDP.
Step 4: Test and Validate
The DGFiP provides a pilot program for businesses to test their e-invoicing setup before the mandate takes effect. Take advantage of this testing period to identify and resolve issues early.
Practical Implications
The September 2026 deadline is approaching rapidly. Even if your business falls into the small company category (with emission obligations starting September 2027), the reception obligation applies from September 2026. This means every French business must be ready to receive electronic invoices within months. Starting preparation now, whether by choosing a PDP, implementing a compliance solution, or simply auditing your current invoicing data, is the best way to ensure a smooth transition when the mandate takes effect.
