Since 1 September 2026, every company registered in France has to be able to receive electronic invoices, and large companies must already issue all of theirs in electronic form. If you run a French SAS or SARL from London, New York, Dubai or Singapore, this reform reaches you exactly as it reaches a founder living in Paris: your company has a SIREN number, it is entered on the trade register, and the tax authority expects it to be plugged into the new circuit. The change is not a vague promise of digital modernisation. It carries fines per invoice, it decides whether your customers can deduct VAT, and it changes what a judge will accept as proof when a bill is disputed. This guide explains, in plain business English, what the French e-invoicing reform requires from a foreign-owned company, how invoices to and from abroad are treated differently, what a defective invoice really costs, and what to do in the next days if your company is not ready yet.
The stakes are practical. A French customer who receives a paper invoice that should have been electronic may still owe you the money, but your company faces a 50 euro fine per invoice. A supplier invoice missing a mandatory detail can cost your company its VAT deduction. And a director who lives abroad cannot plead distance: the obligations attach to the French company, and the calendar is already running. The good news is that the administration has announced a tolerant attitude during the start-up phase, small companies have until September 2027 to issue electronic invoices, and sales to clients outside France follow a lighter track. Here is the full picture, with the exact legal texts and the court decisions that show how judges handle invoice disputes.
I. What the reform in force since 1 September 2026 means for a company owned from abroad
A. Every French company must receive electronic invoices, and large ones must already issue them through an approved platform
The French Ministry of the Economy states the position without ambiguity: the business-to-business e-invoicing reform entered into force on 1 September 2026 (Ministry of the Economy, business guidance). From that date, the obligations apply in two waves. First, every business regardless of size must be able to receive electronic invoices. Whether your French company is a one-person SASU managed from abroad or a subsidiary with fifty employees in Lyon, it must be able to receive invoices in electronic form today. Second, large companies and intermediate-sized companies must issue all their invoices in electronic form and transmit their e-reporting data. Only small and micro businesses keep a grace period: they must be able to issue invoices electronically and transmit their e-reporting data by 1 September 2027. In practice, most foreign founders run small SAS or SARL structures, so the immediate duty is reception, while issuance becomes mandatory next year. But the reception duty is real now, and the tax authority’s own checklist tells businesses to choose a platform for receiving supplier invoices by 1 September 2026 (impots.gouv.fr, what changes for me).
The legal backbone sits in the French Tax Code, known by its acronym CGI. Article 289 states the classic rule: “Tout assujetti est tenu de s’assurer qu’une facture est émise, par lui-même, ou en son nom et pour son compte, par son client ou par un tiers” (CGI, art. 289). An assujetti is a VAT-taxable person, which covers essentially every company doing business in France. On top of this general duty, the new Article 289 bis creates the electronic channel: “l’émission, la transmission et la réception des factures relatives aux opérations mentionnées aux a et d du 1 du I dudit article 289 ainsi qu’aux acomptes s’y rapportant s’opèrent sous une forme électronique, selon des normes de facturation électronique définies par arrêté du ministre chargé du budget, lorsque l’émetteur de la facture et son destinataire sont des assujettis qui sont établis ou ont leur domicile ou leur résidence habituelle en France” (CGI, art. 289 bis). Two points matter for a foreign owner. First, the test is where the companies are established, not where the shareholders live: your SAS registered in Paris is established in France even if you have never set foot there, so its domestic business-to-business invoices fall inside the reform. Second, the text continues: “L’émission, la transmission et la réception des factures électroniques s’effectuent en recourant à une plateforme agréée.” A plateforme agréée, usually called a PDP (Partner Dematerialization Platform) in English, is a private provider registered with the tax administration that routes invoices between supplier and customer and forwards the required data to the administration. There are already about one hundred of them, and the administration publishes the list. Emailing a PDF no longer counts: the invoice must travel through these approved platforms in one of the accepted structured formats, and each invoice carries life-cycle statuses so both sides can track receipt and processing in real time.
A central directory, called the annuaire, routes each invoice to the right platform: the law provides that “l’Etat met un annuaire central à la disposition des plateformes agréées” which “recense les informations nécessaires à l’adressage des factures électroniques aux plateformes agréées des destinataires” (CGI, art. 289 bis, III). Your company is identified there by its SIREN, the nine-digit number issued at registration that appears on the Kbis, the official company identity certificate delivered by the greffe, the registry office of the commercial court. If your company was recently created through the INPI guichet unique, the single online filing portal, and you already hold the Kbis, the SIREN exists and the company is addressable. A liaison office that issues no invoices has nothing to send, but a registered branch (succursale) with its own SIREN that bills French clients is concerned exactly like a subsidiary. The administration has publicly promised that the start-up phase of the reform follows an approach of goodwill and tolerance by the administration toward businesses facing difficulties. Tolerance is not an exemption, and it will not last, but it gives a company that moves now a realistic window to choose its platform, register, and train its accountant without an immediate penalty strike.
B. Sales to clients outside France and purchases from foreign suppliers follow a lighter track, with reverse-charge VAT
Many foreign-owned French companies mostly bill abroad: the Paris SAS invoices the London parent, the Lyon subsidiary bills American clients, the French branch refills stock from a German supplier. The reform handles these cross-border flows through a second mechanism called e-reporting, which means sending the administration the transaction or payment data without sending the invoice itself through the platform. The Ministry explains: where the customer is a private individual or established abroad, the supplier sends the invoice through the usual channel and only transmits the transaction or payment data to its approved platform, which forwards it to the administration. In other words, your invoice to a client in Dubai or New York keeps its usual form, PDF or paper, but its data must still be reported electronically through your platform. The same logic applies in reverse to your purchases from foreign suppliers. This is why choosing a platform matters even for a company with zero domestic sales: the e-reporting duty still runs, on the September 2026 or September 2027 calendar depending on the size of the company.
The VAT treatment of these cross-border invoices follows the reverse-charge rule, and this is where foreign founders most often make expensive mistakes. Article 283 of the Tax Code provides that “la taxe est acquittée par l’acquéreur, le destinataire ou le preneur qui agit en tant qu’assujetti et qui dispose d’un numéro d’identification à la taxe sur la valeur ajoutée en France” (CGI, art. 283). Concretely, when your French company buys services from a supplier with no French establishment, it is your company that accounts for the French VAT on its own VAT return, through its intra-Community VAT number, the individual identifier issued after registration that starts with FR. When your French company sells to a taxable customer in another European Union country, the invoice generally goes out without French VAT and the customer self-assesses it at home. These invoices must show the correct VAT regime and the VAT numbers of both sides; a French company that wrongly charges French VAT to a foreign taxable customer creates a double-tax mess, while a company that forgets to self-assess VAT on foreign purchases understates its return and invites a reassessment. Our dedicated VAT guide walks through registration, the representative for non-European founders, and invoicing discipline in detail (VAT registration for foreign companies), and the founding roadmap covers the bank account, the Kbis and the first filings together (setting up a company as a foreign founder).
Two traps deserve special attention. The first is the American or British parent that “refills” the French subsidiary with monthly management fees and asks for one global invoice per quarter with a round amount and no detail. Under French law that document is fragile: it may fail the mandatory-content rules examined below, it exposes the 15 euro per-defect fine, and in a transfer-pricing audit the administration will treat undetailed fees as the weakest possible evidence. The second trap is the founder who keeps billing from the foreign parent company while the French structure does the real work on the ground. If the French entity is the true supplier in the eyes of the customer, the invoice should come from it, with French VAT where due; parallel billing from abroad does not remove the French reporting duties and can create a permanent-establishment debate that costs far more than any invoice fine. Map every sales flow on one page, decide which entity bills whom, then configure the platform accordingly.
II. How a wrong invoice costs money in France, and how a foreign owner fixes it
A. Fines per invoice, lost VAT deduction, and customers who must pay even a defective bill
French invoice law punishes at three levels, and the amounts rise fast. At the top, Article 1737 of the Tax Code states: “Entraîne l’application d’une amende égale à 50 % du montant” for disguising supplier or customer identity, issuing “une facture ne correspondant pas à une livraison ou à une prestation de service réelle”, or failing to issue an invoice and book the deal (CGI, art. 1737, I). The professional customer is jointly liable: “Le client professionnel est solidairement tenu au paiement de cette amende, qui ne peut excéder 375 000 € par exercice”, reduced to 5 percent capped at 37,500 euros when the deal was properly booked. These are the penalties for fake or missing invoices, and they apply to criminal-style fraud as well as to organised sloppiness. One level down, “Toute omission ou inexactitude constatée dans les factures ou documents en tenant lieu mentionnés aux articles 289 et 290 quinquies donne lieu à l’application d’une amende de 15 €”, capped per invoice at one quarter of the invoiced amount (CGI, art. 1737, II). A wrong VAT rate, a missing SIREN, a forgotten delivery date: each defect is 15 euros, and a file of one hundred sloppy invoices is 1,500 euros per defect type before any other consequence. At the newest level, “Le non-respect par l’assujetti de l’obligation d’émission d’une facture sous une forme électronique dans les conditions prévues à l’article 289 bis donne lieu à l’application d’une amende de 50 € par facture” (CGI, art. 1737, III). Two hundred domestic invoices sent by email instead of through the platform represent 10,000 euros of theoretical fines. The tolerance announced for the launch phase softens the immediate risk, but the scale shows why configuring the platform before September 2027 is not optional for a small company.
Beyond fines, a defective supplier invoice can destroy the VAT deduction, which is often the larger loss. Article 271 allows deduction only for “Celle qui figure sur les factures établies conformément aux dispositions de l’article 289 et si la taxe pouvait légalement figurer sur lesdites factures” (CGI, art. 271, II), and the right arises when “la taxe déductible devient exigible chez le redevable”: “Le droit à déduction prend naissance lorsque la taxe déductible devient exigible chez le redevable” (CGI, art. 271, I). The Paris Court of Appeal restated the mechanics in a February 2024 ruling: “(i) la TVA qui a grevé les éléments du prix d’une opération imposable est déductible de la TVA applicable à cette opération, (ii) le droit à déduction prend naissance lorsque la taxe déductible devient exigible chez le redevable, (iii) la déduction de la taxe est opérée par imputation sur la taxe due par le redevable au titre du mois pendant lequel le droit à déduction a pris naissance et (iv) la taxe déductible dont l’imputation n’a pu être opérée peut faire l’objet d’un remboursement” (CA Paris, 27 February 2024, RG 23/00559: full decision). In that case the court also accepted that the words “TVA acquittée sur les débits” printed on the invoices had properly informed the customer of the supplier’s VAT option. The lesson for a foreign owner is direct: demand compliant supplier invoices, keep the mentions that prove the VAT regime, and never deduct VAT shown on a document that Article 283 forbids, because “La taxe sur la valeur ajoutée facturée dans les conditions définies au 4 de l’article 283 ne peut faire l’objet d’aucune déduction par celui qui a reçu la facture” (CGI, art. 272, 2). Where an invoice was wrong and then corrected, the refund depends on proof of the correction: “L’imputation ou la restitution est subordonnée à la justification, auprès de l’administration, de la rectification préalable de la facture initiale” (CGI, art. 272, 1). Ask the supplier for a corrective invoice before filing, not after the auditor arrives.
The mirror question arises when your own customer refuses to pay, arguing that your invoice is defective. French courts are strict about invoice content but refuse to turn every defect into a free pass for the debtor. The Douai Court of Appeal recalled in January 2026 that “La chambre criminelle de la Cour de cassation a précisé que les mentions exigées par l’article L. 441-9 précité doivent figurer sur les factures, sans qu’il soit nécessaire de se référer aux documents qui les fondent (Crim., 6 décembre 2006, n° 06-82.834, Bull. n° 306, – Voir aussi Com., 7 janvier 2014, n° 13-11.894)”, while adding that “il a été jugé que la sanction du non-respect des règles de facturation, passible de sanctions pénales, ne peut consister en la nullité des factures émises (3e Civ., 19 mars 2013, n° 12-14.147)”. It concluded: “Il s’ensuit que la société Unik ne peut utilement se prévaloir de la disposition précitée pour s’estimer libérer de l’obligation que sous-tend la facture litigieuse, quand bien même il serait démontré que cette dernière ne répondrait pas aux exigences du texte précité” (CA Douai, 8 January 2026, RG 24/03736: full decision). So a customer who received the goods or the service still owes the price even if the invoice lacks a mention; the missing mention exposes the supplier to fines, not the customer to freedom. That is reassuring for unpaid bills, and our recovery guide explains the fast French collection routes (recovering an unpaid French invoice). It does not save the supplier from the auditor: issue a compliant invoice from the start, because the commercial victory and the tax fine are two separate battles.
The content rules themselves sit in the Commercial Code. Article L. 441-9 opens with the principle: “Tout achat de produits ou toute prestation de service pour une activité professionnelle fait l’objet d’une facturation.” It adds the timing and the symmetry of duties: “Le vendeur est tenu de délivrer la facture dès la réalisation de la livraison ou de la prestation de services” while “L’acheteur est tenu de la réclamer” (C. com., art. L. 441-9). The same article lists the mandatory details: names, addresses, billing address if different, date of sale or service, quantity, precise description, unit price excluding VAT, acquired price reductions, payment date, discount terms, late penalties, and the fixed recovery fee. For a foreign director, the operational translation is a checklist inside the billing software: no invoice goes out without the customer SIREN and VAT number verified, the exact service description, the VAT regime stated in words, and the payment terms completed. Company accounts must also be kept “en euros et en langue française” and “Les documents comptables et les pièces justificatives sont conservés pendant dix ans” (C. com., art. L. 123-22). Electronic invoices stored on the platform do not remove the ten-year retention duty; they make it easier to prove.
B. The compliance checklist for a director living abroad, and how to challenge a penalty
Start with the calendar and the company size. If the French company belongs to a large group, issuance in electronic form and e-reporting are due now; if it is a small SAS or SARL, reception is due now and issuance follows by 1 September 2027. Either way, designate one approved platform this quarter, register the SIREN in the directory, and connect the billing software or use the platform’s own invoice editor for low volumes. Test the full loop with a friendly French customer: issue, receive, check the statuses, confirm the administration data feed. Then extend to e-reporting for foreign and private-customer sales, which your accountant should map against the VAT return so the two tell the same story every month. Keep every invoice and its statuses for ten years, in euros and in French, alongside the contracts and delivery proofs that support them. Where the company is brand new, remember the entry duty: “Dans les quinze jours du commencement de ses opérations, souscrire au bureau désigné par un arrêté une déclaration conforme au modèle fourni par l’administration” (CGI, art. 286, I). In practice the INPI filing covers registration, but the fifteen-day logic shows the French reflex: declare first, correct later, never operate invisibly.
Distance changes the organisation, not the rules. A director living abroad should give the French accountant a written mandate covering platform choice, invoice validation, monthly VAT filings, and document retention, with a named contact at the platform provider. Schedule a monthly thirty-minute review of issued invoices, received invoices, rejected flows, and e-reporting matching, because most fines come from unnoticed rejections rather than deliberate fraud. Verify every new French customer and supplier in the directory before the first invoice, and confirm foreign customers’ VAT numbers through the European VIES system so reverse-charge invoices carry the right proof. Separate the roles cleanly: the person who performs the service should not be the only one who validates the invoice, and management fees from the foreign parent need timesheets or deliverables attached, not a single round-figure line. If the bank, the VAT registration and the first hire are still ahead of you, treat invoicing as part of the same launch sequence rather than an afterthought, and read the corporate calendar that ties accounts, tax instalments and filings together (corporate tax calendar).
When a penalty arrives despite these precautions, French law offers a structured path, and speed matters. Start by reading the proposal of reassessment or the fine notice line by line: which invoices, which legal basis, which amounts, which year. Many invoice fines collapse once the company produces the missing platform logs, the corrective invoices, or the proof that the transaction was booked, since booking alone can divide the 50 percent fine down to 5 percent. File a written claim (réclamation) with the tax office within the deadline stated on the notice, attaching the platform transmission reports, the corrected invoices, and the accounting entries. If the claim is rejected, the dispute moves to the administrative court, where the judge checks the facts, the legal basis, and the proportionality of the fine, with appeal to the administrative court of appeal. Parallel criminal exposure for false invoices belongs to a different track and needs a defence lawyer immediately, because statements made to the auditor can travel. Throughout, keep paying what is safely due and contesting the rest: unchallenged fines become final, while a reasoned claim filed on time preserves every option, including settlement (transaction) where the code allows it. A company that kept clean platform records, ten-year archives, and monthly reviews settles from strength; a company with a shoebox of PDFs settles from weakness.
Conclusion
The e-invoicing reform rewards the companies that treat invoicing as infrastructure and punishes those that treat it as paperwork. A foreign-owned French company is fully inside the system from the day its SIREN exists: it must receive electronic invoices today, report its cross-border sales data through its platform, and, depending on its size, already issue electronic invoices or be ready by September 2027. The fine scale runs from 15 euros per defect to 50 euros per non-electronic invoice and up to 50 percent of the amount for false or missing invoices with the customer jointly liable, while a defective supplier invoice can silently erase the VAT deduction the business model relied on. Against these risks, the defences are methodical and affordable: one approved platform, verified directory entries, complete invoice mentions, monthly matching with the VAT return, ten-year archives, and corrective invoices issued before the audit. Courts confirm the balance: a debtor cannot escape payment over a missing mention, but the administration can and will fine the faulty paperwork. Set up the circuit this quarter, use the tolerance window to fix the rough edges, and the French company becomes what it should be for its foreign owner, a billing machine that is boring to auditors and convincing to customers.
