You run your company from London, New York, Dubai or Singapore, you landed French clients, and the invoices went out with your home-country VAT number, your US EIN, or no tax number at all. Months later, a French customer asks for a proper invoice with a French VAT number, your accountant warns that the French tax office, the administration fiscale, may treat those sales as French VAT due, or a formal demand letter, a mise en demeure, already landed on your desk. From abroad, the problem looks like paperwork: get a number, reprint the invoices, move on. French law sees two separate offences where you see one clerical error. The first is the VAT itself, which may have become due in France the day you were paid, whether or not you charged it. The second is the missing registration and the defective invoices, which carry their own fines even if every euro of VAT is eventually paid. This article walks through both layers with the statutes in force verified on 14 September 2026, three binding rulings of the Conseil d’Etat, the highest French administrative court, one appeal ruling on how corrections must be presented, and the official impots.gouv.fr procedure for foreign companies registering for French VAT. It explains every French acronym on first use and gives the distant founder a practical order of operations that works from abroad. Our companion guide on setting up a company in France as a foreign founder describes how to start clean; this article explains how to repair invoices that went out before you were ready.

I. Your Foreign Company Billed French Clients With No French VAT Number: Was French VAT Even Due?

A. Were your services taxed in France: business customers, reverse charge and the permanent-establishment trap?

The starting question is not how to get a number. It is whether French VAT was due at all, because the answer decides who pays, how much interest runs, and which penalties apply. French VAT catches a wide net: « Sont soumises à la taxe sur la valeur ajoutée les livraisons de biens et les prestations de services effectuées à titre onéreux par un assujetti agissant en tant que tel » (General Tax Code, Article 256, I). Any supply of goods or services for consideration by a taxable person acting as such falls in principle within VAT. The decisive follow-up is where the transaction is located, since a French customer does not automatically mean French VAT.

For services sold to a French business customer, a taxable person acting as such, the place of supply is France: « Le lieu des prestations de services est situé en France : 1° Lorsque le preneur est un assujetti agissant en tant que tel et qu’il a en France : a) Le siège de son activité économique », its registered office or principal place of business, « b) Ou un établissement stable auquel les services sont fournis », a permanent local presence to which the services are supplied, « c) Ou, à défaut du a ou du b, son domicile ou sa résidence habituelle » (General Tax Code, Article 259, 1°). Business-to-business services for a French-registered client are therefore French-taxable as a rule. The mirror rule matters just as much: where the customer is a private individual, a non-taxable person, services are located where the provider sits, « si le prestataire : a) A établi en France le siège de son activité économique », and the equivalent for a stable establishment or home (same article, 2°). A foreign company with no French presence that sells services to French consumers is generally outside French VAT, subject to sector exceptions that must be checked case by case, while the same company selling the same services to French VAT-registered businesses is inside it.

Being inside French VAT does not always mean the foreign provider writes the cheque. Where business-to-business services covered by Article 259, 1° « sont fournies par un assujetti qui n’est pas établi en France, la taxe doit être acquittée par le preneur », the customer accounts for the tax under the reverse-charge mechanism, called autoliquidation (General Tax Code, Article 283, 2). The same logic covers certain goods: where a supply mentioned in Article 259 A is made by a business not established in France, « 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 », and the amount is reported on the VAT return mentioned in Article 287 (same article, 1). In the clean case, the foreign company issues an invoice without French VAT, the French customer self-assesses it, and nobody needs a French VAT number for the provider. Two traps destroy this clean case, and both appear constantly in files handled from abroad.

The first trap is billing the wrong customer profile. The tax administration’s own guidance states that registration with VAT returns, the CA3 return form, is mandatory for billing transactions subject to French VAT to private individuals, entities or businesses without French VAT identification, and the VAT collected must then be reported and paid where it exceeds deductible VAT (impots.gouv.fr, Immatriculation à la TVA, updated 3 March 2025). The same page lists distance sales of goods from another State to French private individuals, intra-Community supplies from France, exports from France and import reverse-charge operations. The distance-selling safety net for small operators covers combined intra-Community distance sales plus telecom, broadcasting and electronic services below 10,000 euros excluding tax. A foreign e-commerce company that stored goods in France or shipped to French consumers above the threshold and billed without a French number is not a reverse-charge case at all: it is the taxable person, and registration was due before the first invoice.

The second trap is the hidden French presence. On 15 June 2023 the Conseil d’Etat decided the case of a Luxembourg company supplying administrative, financial, tax, legal and IT services to its two French subsidiaries, which had reverse-charged the VAT as intra-Community exchanges from Luxembourg (CE, 15 June 2023, No. 465719, full text on Légifrance). The French administration argued the Luxembourg parent was the legally liable party, and added an 80 percent surcharge for hidden activity. The court confirmed the test: « le redevable de la taxe sur la valeur ajoutée afférente est le prestataire qui les fournit s’il est lui-même établi en France. Doit être regardé comme tel le prestataire qui a en France un établissement stable depuis lequel les prestations sont fournies et qui présente un degré suffisant de permanence et une structure apte, du point de vue de l’équipement humain et technique, à rendre possibles, de manière autonome, les prestations de services considérées. » (CE, 15 June 2023, No. 465719) The facts were brutal: a 12.5 square-metre office in Luxembourg where staff could not physically perform the services, six employees declared and living in France, four of them also employed by the French subsidiary, and the disputed work performed from France by two named managers. Reverse charge collapsed, the provider owed the VAT, and the 80 percent surcharge survived. A foreign founder whose French subsidiary’s staff, desks and servers actually deliver the billed services should read this ruling twice: the group’s org chart does not decide where VAT is due, the human and technical means do.

An older ruling completes the picture for providers outside the European Union. On 9 October 2019 the Conseil d’Etat dealt with services billed to a French insurance agent by a Moroccan company, held taxable in France, with the customer liable under reverse charge and the provider jointly liable: « la taxe doit être acquittée par le preneur. Toutefois, le prestataire est solidairement tenu avec ce dernier au paiement de la taxe » (CE, 9 October 2019, No. 416107, full text on Légifrance, wording applicable to the dispute period). The lesson for a non-EU company that already billed French clients without any French number: even where the customer should have reverse-charged, the provider can be pursued jointly, and hoping the customer’s return fixes everything is not a strategy.

B. Why is the missing VAT number a second offence: registration duty, invoice mentions and the SIEE route?

Assume French VAT was due, whether payable by you or by your customer. The missing number then opens a second front: registration and invoicing duties that exist independently of the tax itself. Every taxable person must declare its activity fast: « 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 » (General Tax Code, Article 286). The declaration duty runs from the start of operations, not from the first audit, not from the first demand letter. A foreign company that traded in France for months without declaring is already late on day sixteen.

Registration produces the individual identification number, the numéro individuel d’identification, issued under Article 286 ter, the number under which supplies are made. Invoicing duties then attach to every transaction: « 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 » for supplies to another taxable person or non-taxable legal person that are not exempt (General Tax Code, Article 289, I). A government decree sets the mandatory mentions, and the Conseil d’Etat recalled them in 2025: « Les mentions obligatoires qui doivent figurer sur les factures en application du II de l’article 289 du code général des impôts sont les suivantes : / 1° Le nom complet et l’adresse de l’assujetti et de son client ; / 2° Le numéro individuel d’identification attribué à l’assujetti en application de l’article 286 ter du code général des impôts et sous lequel il a effectué la livraison de biens ou la prestation de services » (CE, 19 May 2025, No. 474967, full text on Légifrance). An invoice without your French VAT number, or without the client’s full name and address, is a defective invoice from day one, and correcting it later does not erase the period during which it circulated.

The practical registration route for a company with no French establishment is documented step by step by the tax administration: in short, a company with no stable French establishment that carries out any listed operation requiring customs-only registration or VAT returns must register for French VAT (impots.gouv.fr, Immatriculation à la TVA). The competent office is the Service des Impôts des Entreprises Étrangères, the SIEE, the foreign-companies tax office, part of the Direction des Impôts des Non-Résidents, the DINR, the non-residents tax directorate, at 10 rue du Centre, TSA 20011, 93465 Noisy-le-Grand Cedex, with registration filed online through the single company formalities portal at formalites.entreprises.gouv.fr. Companies established in the European Union or in listed third countries with mutual assistance arrangements, a list that includes the United Kingdom, Norway, Japan, Australia, Mexico, South Korea, Ukraine and others, need no tax representative but may appoint an agent. Companies from other non-EU States must appoint a représentant fiscal, a tax representative established in France and itself registered for French VAT, and the locally competent office becomes the one handling that representative’s own filings. Mandatory attachments include the foreign commercial-register certificate or equivalent, the articles of association with a free French translation of key points, or a sworn translation, a traduction assermentée, for statutes drafted in a non-EU language, plus the identity document of the legal representative. Founders from the United States, the Gulf or Asia regularly lose weeks here: an uncertified English translation of Delaware or DIFC documents is sent back, and the clock keeps running while the file sits incomplete. A parallel official guide covers the same ground for foreign companies active in France without an establishment (impots.gouv.fr, Entreprise étrangère, j’ai une activité en France).

Two consequences follow that founders consistently underestimate. First, the registration duty and the VAT debt are cumulative, not alternative: paying the VAT late does not cure the late registration, and registering today does not validate yesterday’s numberless invoices. Second, the invoice fines described below apply per defective invoice, so a company that issued hundreds of numberless invoices to French clients faces arithmetic that dwarfs the VAT itself. Mapping every invoice before acting is therefore the indispensable first step, and it is the subject of the repair sequence in Part II.

II. How Do You Fix Invoices Issued Without a Number and Pay From Abroad?

A. How do you register, correct the invoices and pay the VAT and interest now?

Repair follows a fixed order, and skipping a step usually makes the file worse. Step one is the invoice map: list every invoice issued to French customers since operations began, with date, amount, customer identity and VAT status, nature of the supply, and place of payment. Separate three piles: business customers with a French VAT number, where reverse charge by the customer may already have settled the VAT and your exposure is mostly registration plus invoice mentions; private individuals, entities or businesses without a French VAT number, where you are the taxable person and must report and pay; and operations tied to a possible French permanent presence, staff, offices or equipment in France, where the Luxembourg ruling above warns that reverse charge may collapse entirely. Date each pile by payment, because for services the tax becomes due on collection: « Pour les prestations de services autres que celles visées au b bis, lors de l’encaissement des acomptes, du prix, de la rémunération ou, sur option du redevable, d’après les débits » (General Tax Code, Article 269). VAT due follows cash, not the invoice date, which often moves the debt across return periods.

Step two is registration without delay. File through formalites.entreprises.gouv.fr toward the SIEE, appoint a tax representative if your home State requires one, and complete the documentary set, register certificate, statutes with the correct level of translation, representative’s identity papers, before the administration asks. The 2025 official page details the EE0 form frames for businesses using import reverse charge, so a company that also imports goods should flag that scheme in the application. Registration produces the French VAT number that all corrected invoices must carry. Do not backdate the number onto old invoices as if it existed at the time: issue corrective documents, factures rectificatives, that reference the original invoice, state the correct mentions including the newly issued number, and show the VAT now charged or the reverse-charge wording where the customer remains liable. Keep the originals and the corrections stapled together in the accounts; an auditor who finds only rewritten invoices will treat them as concealment evidence rather than cooperation.

Step three is the returns and the money. Every identified VAT taxable person « est tenu de remettre au service des impôts dont il dépend et dans le délai fixé par arrêté une déclaration conforme au modèle prescrit par l’administration » (General Tax Code, Article 287, 1). Businesses under the standard real regime file the CA3 monthly and pay monthly; « Lorsque la taxe exigible annuellement est inférieure à 4 000 €, ils sont admis à déposer leurs déclarations par trimestre civil », quarterly filing by calendar quarter (same article, 2). Report the late VAT on the correct period’s return or on a clearly identified corrective filing, never buried inside a current period without explanation, and pay immediately. Late payment automatically bears interest: « Toute créance de nature fiscale, dont l’établissement ou le recouvrement incombe aux administrations fiscales, qui n’a pas été acquittée dans le délai légal donne lieu au versement d’un intérêt de retard », at « Le taux de l’intérêt de retard est de 0,20 % par mois », running from the first day of the month after the tax was due (General Tax Code, Article 1727). At 0.20 percent monthly, roughly 2.4 percent yearly, interest is the cheapest part of delay, which is exactly why paying the principal fast, even while penalty discussions continue, is always the right move.

Step four is presenting the correction so that it counts as spontaneous. The Versailles appeal court examined a software company that had under-declared collected VAT across three years and claimed it had regularised part of the debt before the audit (CAA Versailles, 15 November 2022, No. 20VE00208, full text on Légifrance). The court refused to recognise any spontaneous correction: the alleged 2011 payments were undocumented, the one documented late return for December 2011 came after the reassessment proposal, gave neither the period concerned nor its corrective character, while the user instructions were clear enough about filling box 3C (CAA Versailles, 15 November 2022, No. 20VE00208), and the amount covered only part of the debt without explanation. The negative checklist is the useful part: correct before any audit notice, identify the exact period, mark the filing as corrective, use the right boxes, pay the full amount, and keep the receipts. A founder correcting from abroad should wire the payment, screenshot the debit, archive the return acknowledgment, and send the bundle to the SIEE by tracked message the same week. Corrections presented this way do not guarantee penalty relief, but corrections presented any other way guarantee it will be refused.

B. How do you cut the penalty bill: late filing, deliberate failure, hidden activity and invoice fines?

With the VAT paid and the invoices corrected, four penalty layers remain, each with its own trigger, rate and defence. The first layer punishes late returns: « Le défaut de production dans les délais prescrits d’une déclaration ou d’un acte comportant l’indication d’éléments à retenir pour l’assiette ou la liquidation de l’impôt entraîne l’application, sur le montant des droits mis à la charge du contribuable ou résultant de la déclaration ou de l’acte déposé tardivement, d’une majoration de : a. 10 % en l’absence de mise en demeure ou en cas de dépôt de la déclaration ou de l’acte dans les trente jours suivant la réception d’une mise en demeure d’avoir à le produire dans ce délai ; b. 40 % lorsque la déclaration ou l’acte n’a pas été déposé dans les trente jours suivant la réception d’une mise en demeure d’avoir à le produire dans ce délai ; c. 80 % en cas de découverte d’une activité occulte » (General Tax Code, Article 1728, 1). The 30-day rule is the single most valuable tactic in the whole file: a formal demand letter that is answered with a full filing within thirty days caps the surcharge at 10 percent instead of 40. From abroad, this means organising proof of receipt, diary dates and a preparer on standby before the letter arrives, because international mail delays do not extend the thirty days.

The second layer punishes inaccuracies in filed returns: « Les inexactitudes ou les omissions relevées dans une déclaration ou un acte comportant l’indication d’éléments à retenir pour l’assiette ou la liquidation de l’impôt ainsi que la restitution d’une créance de nature fiscale dont le versement a été indûment obtenu de l’Etat entraînent l’application d’une majoration de : a. 40 % en cas de manquement délibéré » (General Tax Code, Article 1729, wording recalled in CAA Versailles No. 20VE00208). Deliberate failure must be proved by the administration: « En cas de contestation des pénalités fiscales appliquées à un contribuable au titre des impôts directs, de la taxe sur la valeur ajoutée et des autres taxes sur le chiffre d’affaires, des droits d’enregistrement, de la taxe de publicité foncière et du droit de timbre, la preuve de la mauvaise foi et des manœuvres frauduleuses incombe à l’administration » (Book of Tax Procedures, Article L.195 A, as quoted by CAA Versailles, 15 November 2022, No. 20VE00208). But the Versailles ruling shows how that burden is met in practice: the administration proved intent from the scale of the shortfalls, a previous audit that had already reminded the company of the collection-based exigibility rules, and a manifest mismatch between the customer ledger and the collected-VAT account that the company could not have missed for three straight years, so that « l’administration doit être regardée comme apportant la preuve, qui lui incombe, du caractère intentionnel des insuffisances de déclaration de TVA et établit ainsi la volonté du contribuable d’éluder l’impôt. » (CAA Versailles, 15 November 2022, No. 20VE00208) A foreign company arguing good faith should therefore assemble the opposite file: first French operation, immediate registration once advised, full spontaneous payment, consistent filings at home, and no prior French reassessment. The contrast with a repeat shortfall across several years is precisely what judges weigh.

The third layer is the 80 percent surcharge for hidden, occulte, activity, the heaviest weapon in this file. The Conseil d’Etat framed it in the Luxembourg case: « dans le cas où un contribuable n’a ni déposé dans le délai légal les déclarations qu’il était tenu de souscrire, ni fait connaître son activité à un centre de formalités des entreprises ou au greffe du tribunal de commerce », the commercial-court registry office, « son activité est réputée occulte s’il n’est pas en mesure d’établir qu’il a commis une erreur justifiant qu’il ne se soit acquitté d’aucune de ses obligations déclaratives. » (CE, 15 June 2023, No. 465719) Critically for foreign groups: « S’agissant d’un contribuable qui fait valoir qu’il a satisfait à l’ensemble de ses obligations fiscales dans un Etat autre que la France, la justification de l’erreur commise doit être appréciée en tenant compte de l’ensemble des circonstances de l’espèce et notamment du niveau d’imposition dans cet autre État et des modalités d’échange d’informations entre les administrations fiscales des deux Etats. » (CE, 15 June 2023, No. 465719) A Luxembourg parent declaring everything at home still lost, because it had declared nothing anywhere on the French establishment’s income and its wrong reverse-charge position « ne pouvait tenir lieu de déclaration » (CE, 15 June 2023, No. 465719), could not stand in for a return. The defence path is narrow but real: prove genuine error with home-country filings covering the same income, contemporaneous advice treating the supplies as reverse-charged, and immediate French registration once the analysis changed. What never works is silence plus a technically wrong self-help position maintained for years.

The fourth layer is the invoice fines, and here the most recent Conseil d’Etat ruling helps honest businesses. Article 1737 opens with the disguise fine: « Entraîne l’application d’une amende égale à 50 % du montant : 1. Des sommes versées ou reçues, le fait de travestir ou dissimuler l’identité ou l’adresse de ses fournisseurs ou de ses clients, les éléments d’identification mentionnés aux articles 289 et 289 B et aux textes pris pour l’application de ces articles ou de sciemment accepter l’utilisation d’une identité fictive ou d’un prête-nom », while ordinary defects draw « une amende de 15 € » per omission, capped per invoice at one quarter of the invoiced amount (General Tax Code, Article 1737, current wording verified 14 September 2026). The same article adds a first-offence safety valve worth knowing before panicking over hundreds of old invoices: « Les amendes mentionnées au 3 du I et aux II, III et IV du présent article ne sont pas applicables en cas de première infraction commise au cours de l’année civile en cours et des trois années précédentes lorsque l’infraction a été réparée spontanément ou dans les trente jours suivant une première demande de l’administration. » (General Tax Code, Article 1737, V). A first invoice offence in four years, repaired spontaneously or within thirty days of the administration’s first request, escapes those fines entirely, which is one more reason to correct the whole invoice set now rather than invoice by invoice after each auditor letter. On 19 May 2025 the Conseil d’Etat drew the line between the two: « L’omission, sur une facture, de l’identité, de l’adresse ou des éléments d’identification du client ou du fournisseur n’est susceptible de constituer une dissimulation, au sens et pour l’application de ces dispositions, éclairées par les travaux préparatoires de la loi du 29 décembre 1984 de finances pour 1985 dont elles sont issues, que si l’administration établit que cette omission, non seulement a revêtu un caractère volontaire, mais aussi a été motivée par une intention frauduleuse. » (CE, 19 May 2025, No. 474967) The ruling annulled the appeal decision and sent the case back. For a foreign company whose invoices merely lack a VAT number because it had none, this is the key shield against the 50 percent fine: a missing number from administrative delay is not disguise, unless the administration proves a voluntary omission driven by fraudulent intent. Keep the SIEE application receipts, the requests for the number, and the correspondence showing when it was issued; they are the documentary proof that the omission was suffered, not plotted. Note the fines were uncovered through the invoicing investigation power, the tax administration’s invoicing investigation power under Article L.80 F of the Book of Tax Procedures, as the ruling records (CE, 19 May 2025, No. 474967), so a company that corrects its invoices should expect the corrected set to be examined line by line, and should make sure every mandatory mention is right this time.

Conclusion

A foreign company that billed French clients without a French VAT number faces two files, not one. The VAT file turns on where the supplies were located and who was liable: business customers in France generally pull services into French VAT with the customer reverse-charging, unless your own French staff and premises make you the liable provider, while sales to private individuals without French VAT identification put the reporting and payment on you. The compliance file turns on registration within fifteen days of starting, correct invoice mentions including the identification number, and returns on the CA3 with interest at 0.20 percent monthly until payment. The repair order that works from abroad is fixed: map every invoice by customer profile and payment date, register through the SIEE with the right translations and representative, issue identified corrective invoices, file the correct periods with box-level precision, and pay the principal immediately while penalty discussions run. The penalty fight then plays on four tables: answer any formal demand within thirty days to hold late filing at 10 percent, contest deliberate failure with evidence of first-time good faith since the administration bears the burden of bad faith, rebut hidden activity with home-country filings and contemporaneous advice, and push invoice defects down from the 50 percent disguise fine to the 15-euro omission scale using the 2025 ruling’s voluntary-plus-fraudulent-intent test. None of this requires flying to Paris; all of it requires acting before the audit notice arrives, because after that date every correction is examined as damage control rather than cooperation.
