What happens if your business is not ready on 1st September 2026 for France’s e-invoicing and e-reporting requirements

France’s electronic invoicing and e-reporting reform reaches its first major implementation date on 1st September 2026.

For businesses still preparing their systems, the immediate question is no longer simply what the reform requires but rather what happens if they are not fully ready when the obligations take effect.

Which obligations begin on 1st September 2026?

 The first point is to identify which deadline applies to the business.

From 1st September 2026:

• All businesses established in France and subject to VAT must be able to receive electronic invoices through an approved platform.
• Large enterprises and intermediate-sized enterprises established in France must be able to issue electronic invoices for transactions within the scope of the reform.
• Large enterprises and intermediate-sized enterprises must also transmit relevant transaction and payment information through the e-reporting system. This applies to both French established and non-established businesses VAT registered in France.

SMEs, small businesses and micro-enterprises, generally have until 1st September 2027 to begin issuing electronic invoices and meeting their corresponding e-reporting obligations. However, French established SMEs must still be able to receive electronic invoices from 1st September 2026.

Businesses should therefore avoid assuming that the 2027 issuance deadline means they have no obligations in 2026.

What if the business has not selected an approved platform?

 Every affected business must select an approved platform to receive its electronic invoices. Where the French tax administration identifies that a business has not appointed an approved receiving platform, it may issue a formal notice requiring the business to comply within three months.

If the business remains non-compliant at the end of that period, a €500 penalty may be imposed. A further formal notice will then be issued. Continued non-compliance can result in a €1,000 penalty, followed by additional €1,000 penalties for each subsequent three-month period of continued non-compliance.

In principle, this means that a penalty should not arise automatically on 2nd September 2026 solely because the platform-selection project is incomplete. Nevertheless, the formal-notice procedure should not be treated as an additional implementation period. A business without a receiving platform may be unable to receive or process suppliers’ invoices correctly, potentially disrupting payment approval, VAT recovery and relationships with suppliers.

Can invoices temporarily be sent by email or as PDFs?

 For businesses required to issue electronic invoices from September 2026, sending an ordinary PDF by email does not satisfy the new obligation.

Invoices within the scope of the reform must be issued and transmitted through an approved platform in one of the permitted structured or hybrid formats.

French tax authority guidance recognises that an alternative channel may sometimes be needed to maintain business continuity during a temporary technical incident. For example, a copy might be exchanged outside the platform so that the customer can continue processing the transaction.

However, this does not replace the legal electronic-invoicing process. The invoice must subsequently be transmitted or regularised through the proper channel as soon as possible.

Subject to the tolerance mentioned above during the implementation phase, failure to issue an invoice electronically when required can result in a penalty of €50 per invoice, subject to an annual ceiling of €15,000.

What if the e-reporting system is not ready?

For businesses subject to e-reporting from 1st September 2026 should continue recording its transactions, issuing invoices where required and collecting the information needed for e-reporting. It should:

• identify the affected transactions and reporting periods;
• retain the underlying data;
• record when the incident began;
• preserve error messages and correspondence with its platform or software provider;
• transmit unaffected information where possible; and
• regularise missing or delayed information as soon as the system becomes available.

Failure to comply with the e-reporting obligations can result in a penalty of €500 per required transmission, capped at €15,000 per calendar year. The first-infringement safeguard may also apply where the failure is corrected voluntarily or within 30 days of the administration’s first request.

Will penalties be imposed immediately from 1st September 2026?

 The French tax administration has confirmed that penalties will not be imposed at the start of the reform on businesses acting in good faith that encounter genuine difficulties and undertake the necessary work to regularise their position.

During the initial implementation period, the administration intends to adopt an approach based on tolerance, dialogue and proportionality. It will consider factors such as the nature of the problem, the steps already taken by the business, the extent of its compliance, the quality of its supporting documentation and how quickly outstanding invoices or data are regularised.

This is not a postponement of the reform or a general exemption from penalties. The statutory obligations still take effect on 1st September 2026. The tolerance is intended to assist businesses experiencing genuine and documented implementation difficulties. It will not protect businesses that have made no effort to prepare, refuse to enter the new system or continue using non-compliant processes without taking corrective action.

Businesses should therefore retain evidence of their preparations, including platform contracts, implementation timetables, testing records, technical support requests, error messages and planned corrective actions.

 What should a business do if it knows it will not be ready?

The priority should be to establish a controlled and documented route to compliance rather than wait for a complete system solution.

At a minimum, the business should:

• Confirm whether it is classified as a large enterprise, intermediate-sized enterprises, SME or micro-enterprise.
• Select an approved platform and ensure its selection is recorded in the central directory
• Where electronic invoicing applies to the business, prioritise the ability to receive supplier invoices by 1 September 2026.
• Map transactions between domestic B2B e-invoicing, B2C or international e-reporting, public-sector invoicing and excluded transactions.
• Establish a temporary process for identifying and later regularising failed invoices and reporting transmissions.
• Retain evidence of testing, implementation decisions, incidents and communications with software providers.
• Inform affected customers and suppliers where operational difficulties could delay invoice processing.
• Avoid transmitting knowingly inaccurate information simply to meet a deadline.

French guidance places considerable emphasis on demonstrating an active compliance trajectory. Evidence that the business selected a platform, tested its systems, investigated failures and promptly regularised affected transactions will be materially stronger than an undocumented decision to continue using existing processes.

 The practical conclusion

Being unprepared on 1st September 2026 will not automatically bring business operations to a halt nor create immediate penalties. However, the tolerance relating to penalties being imposed during the implementation phase should not be mistaken for an extension of the deadline. Continued inaction or a failure to address non-compliance will ultimately disrupt invoicing, delay payments and ultimately expose the business to financial penalties.

Businesses should focus on the essentials by appointing an approved platform, identify the transactions within scope and establish a documented process for resolving and regularising failures. The ability to demonstrate genuine preparation and prompt corrective action may prove as important as the technical solution itself.
