Businesses in Mayotte, a French overseas department in the Indian Ocean, have until September 1, 2026, to be ready to receive electronic invoices under a nationwide overhaul of business-to-business billing.
The change applies to every company subject to value-added tax (VAT) in France, including Mayotte. Shanyce Mathias Ali, a journalist at the Journal de Mayotte, reported in mid-June that local business owners are already preparing for the shift.
The rule is straightforward on paper but demanding in practice: any transaction between VAT-liable businesses established in France will have to go through a state-approved platform. Traditional mail, a PDF emailed to a client, or a paper invoice will no longer meet the requirement.
September 2026 is the receiving deadline; sending requirements depend on company size
France’s rollout is staggered by company size. The obligation to receive electronic invoices takes effect for all businesses on September 1, 2026, regardless of how large or small they are.
The obligation to issue electronic invoices follows a separate timeline:
| Catégorie d’entreprise | Date d’entrée en vigueur |
|---|---|
| Grandes entreprises et entreprises de taille intermédiaire (ETI) | 1er septembre 2026 |
| PME et micro-entreprises | 1er septembre 2027 |

In practical terms, large companies and mid-sized firms (known in France as “ETI,” or entreprises de taille intermédiaire) must be ready to both send and receive e-invoices starting in fall 2026. Small businesses and micro-enterprises in Mayotte get an extra year to set up tools for sending e-invoices, but they still must be able to receive them beginning September 2026.
A government-approved platform is mandatory
One technical point is non-negotiable: invoices can’t be routed through just any digital tool. Each business must designate a filing platform registered with the French tax administration, either directly or through a compliant solution—because that choice determines whether exchanges are legally valid.
The tax administration publishes a list of approved partner dematerialization platforms, known as PDPs. Businesses that still haven’t chosen a platform are, with three months to go before the deadline cited in the article, already behind.
The reform also includes a parallel requirement known as “e-reporting,” which involves transmitting transaction data to the administration. That reporting flow follows the same schedule as electronic invoicing, since both measures are tied to the same regulatory text.
Ce que la dématérialisation impose aux entreprises mahoraises
Mayotte is fully included in the national rollout—no special exemption
Mayotte is explicitly included in the reform’s territorial scope alongside French Guiana, Saint-Pierre-and-Miquelon, Saint-Barthélemy, Saint-Martin, New Caledonia, French Polynesia, and Wallis and Futuna. The island is not treated as a special case: the same rules apply on the same deadlines.
But the local business landscape could make the transition harder. The article notes that Mayotte has a very high share of micro-enterprises and very small firms, many of them with limited digital management tools. Upgrading systems is described as a significant technical and financial adjustment for companies emerging from several years of successive crises.
Business owners who move now still have time to test platforms, train staff, and secure invoicing workflows before the requirement becomes enforceable. Those who wait until the September 2026 back-to-business period risk scrambling to comply under pressure.
