The reform comes into force as of September 1, 2026 and all businesses subject to VAT are affected, which is what you need to know and do now.
In a January 2026 study, 48% of French self-employed people cite the lack of information as the main obstacle to their compliance and 37% still do not make the difference between a simple PDF sent by email and a real electronic invoice. Don't be a part of these numbers.
Announced several times over the years, the reform of electronic invoicing is now on the agenda. As of September 1, 2026, all French companies subject to VAT must be able to receive electronic invoices via a platform approved by the State. For large companies and ETIs, the emission obligation also comes into force on the same date, but for SMEs, VSEs and micro-entrepreneurs, it will apply as of September 1, 2027.
Five months is short, here's all you need to understand.
Electronic invoicing or e-invoicing is not just sending a PDF by email, it is a structured digital document, in a standard format recognized by the tax authorities (Factur-X, UBL or CII), transmitted via an approved platform.
The reform also introduces e-reporting: the obligation to transmit to the tax authorities data relating to transactions that are not the subject of an electronic invoice, in particular sales to individuals (B2C) and international transactions.
In summary: the entire billing chain between professionals will go through a common, controlled and traced pipe, this is a structural turning point for the accounting of French companies.
Opening of a pilot environment to test flows without penalties.
Mandatory receipt of electronic invoices for all companies, mandatory issuance for large companies and ETIs, start of e-reporting.
Mandatory issuance for all SMEs, VSEs and micro-entrepreneurs, complete generalization of e-reporting.
Attention: even if you are a micro-enterprise and the emission obligation does not apply to you until 2027, you must be able to receive electronic invoices as early as September 2026. This obligation to receive is universal, do not underestimate it.
The reform has teeth, here are the penalties provided for in the 2026 finance law:
Are you subject to VAT, even with a basic exemption? If yes, you are concerned by the reception as early as September 2026.
80 platforms are now registered, compare them according to your size, your ERP and your volume of invoices.
Integration with your accounting software, updating mandatory information on your invoices, training your teams.
The pilot environment has been open since February 2026, take the opportunity to simulate your flows without the risk of penalty.
Beyond the regulatory constraint, this reform brings real operational opportunities. By automating the transmission of invoices, businesses can hope to reduce payment deadlines and make their accounting more reliable in real time and alleviate their reporting obligations, in particular thanks to the automatic pre-filling of VAT returns in due course.
For entrepreneurs and managers of VSE/SMEs based throughout France, it is also an opportunity to rethink the accounting organization and to gain efficiency. Constraint becomes an advantage if it is anticipated early enough.
The key : do not wait until summer 2026 to start, selecting a platform, integrating it technically and training teams takes time and the companies that start now will be the ones that will experience the transition most peacefully.
