You live in London, New York or Dubai, and your French company operates in Paris, Lyon or Bordeaux through an accountant you meet twice a year. One morning that accountant forwards you a letter from the DGFiP, the Direction générale des Finances publiques, the French tax authority: your SAS, the simplified joint-stock company most foreign founders choose, is about to undergo a vérification de comptabilité, the standard on-site audit of a company’s books. The letter lists three financial years, names the inspector, and sets a first meeting within a few weeks. You cannot fly over for every appointment, your French is business-level at best, and the figures at stake look abstract until the administration converts them into a reassessment loaded with 40% penalties and monthly late interest. This guide walks you through the entire procedure exactly as it applies to a director based abroad: what the inspectors are allowed to do inside your company, which papers you must produce and within which deadlines, how the proposed reassessment and its penalties are built, and every route for challenging them without moving back to France, from the line manager and the departmental interlocutor to the advisory commission and the administrative judge.

I. Your French Company Faces a Tax Audit From Abroad: What the Inspectors Check and Which Papers You Must Produce

A. The Audit Notice and the On-Site Verification: Your Rights From the First Day

Everything starts with the avis de vérification, the formal audit notice sent or handed to the company before any examination begins. This document is not a courtesy letter, it is a procedural safeguard, and the tax procedure code, the LPF, the Livre des procédures fiscales, punishes any omission with nullity: “Cet avis doit préciser les années soumises à vérification et mentionner expressément, sous peine de nullité de la procédure, que le contribuable a la faculté de se faire assister par un conseil de son choix.” In plain terms, the notice must state which years are audited and remind you, on pain of the whole procedure being void, that you may be assisted by an adviser of your choice. When you live abroad, that single sentence is your most valuable asset: it allows a Paris lawyer or your French accountant to stand in for you from day one. The notice also tells you that the charter of the audited taxpayer’s rights and obligations, the charte des droits et obligations du contribuable vérifié, is available on the tax authority’s website or on simple request. Ask for it immediately and read it, because the inspectors will assume you know it (Article L47 of the tax procedure code).

The same article adds a second protection that foreign directors constantly underestimate: “L’examen au fond des documents comptables ne peut commencer qu’à l’issue d’un délai raisonnable permettant au contribuable de se faire assister par un conseil.” The substantive review of your books cannot start until a reasonable period has passed so that you can arrange to be assisted. In practice, when the inspector calls to fix the first appointment, you are entitled to say that your counsel is abroad or unavailable and to agree on a later date. Use that time to gather your files and to sign a written mandate, a mandat, authorising your lawyer or accountant to receive documents, attend meetings and sign correspondence in your name. Mail from the SIE, the Service des impôts des entreprises, the local corporate tax office handling your file, goes to the company’s registered seat, so make sure your domiciliation agent or your accountant actually forwards registered letters the day they arrive. An audit lost because nobody opened the mail is the most common and the most avoidable disaster for companies run from abroad (Article L47 of the tax procedure code).

On the agreed day, the inspector comes to you. The rule is stated in article L13 of the procedure code: “Les agents de l’administration des impôts vérifient sur place, en suivant les règles prévues par le présent livre, la comptabilité des contribuables astreints à tenir et à présenter des documents comptables.” The audit takes place on the company’s premises, most often in practice at your accountant’s office, and it can only move elsewhere if you and the administration agree. There is one exception you should know about: in a surprise intervention, a contrôle inopiné aimed at recording the physical state of the business or the existence of accounting documents, the notice and the charter are handed over at the start of the on-site findings. Even then, the in-depth review of the books can only begin after that reasonable delay allowing you to call in counsel (Article L13 of the tax procedure code).

What exactly will the inspector examine? Three taxes concentrate almost all the risk for a foreign-owned operating company: corporate income tax, the IS, impôt sur les sociétés, value added tax, the TVA, taxe sur la valeur ajoutée, and the consistency of the commercial books that support both. The starting point is always the FEC, the fichier des écritures comptables, the standardised electronic accounting file every company using computerised accounts must be able to hand over. Around it, the inspector will ask for sales and purchase invoices, client and supplier contracts, bank statements, payroll records, and, where your French company belongs to an international group, the intra-group agreements and transfer pricing documentation justifying the management fees, royalties or interest paid abroad. Keep in mind that a slimmer remote procedure also exists, the examen de comptabilité, conducted from the inspector’s desk on documents you send over, but the classic vérification de comptabilité remains an on-site exercise with meetings, questions and a running dialogue.

That dialogue is not optional, it is a legal guarantee called the débat oral et contradictoire, the oral adversarial debate: throughout the audit, the inspector must discuss his findings with you so that you can respond before anything is finalised, and the process normally closes with a synthesis meeting, the réunion de synthèse. Courts take this guarantee seriously but they also place the burden of proof on the company complaining about it. The Paris administrative court of appeal, the CAA, cour administrative d’appel, put it this way in a ruling of 17 July 2023, case number 22PA02929: “c’est au contribuable qui allègue que les opérations de vérification ont été conduites sans qu’il ait eu la possibilité d’avoir un débat oral et contradictoire avec le vérificateur de justifier que ce dernier se serait refusé à un tel débat.” In that case the company argued that the inspector had visited its hair salon only twice and had therefore denied it any real debate, but the court answered that the proposed reassessment itself recorded several meetings and exchanges with the manager, so the complaint failed. The lesson for a director living abroad is direct: never skip a meeting, always be represented, take written minutes of every discussion, and answer each question in writing. If one day you claim there was no debate, you will have to prove that the inspector refused it, and a file full of meeting notes is the only way to do so (Paris administrative court of appeal, 17 July 2023, no. 22PA02929).

One last shield concerns time. For small and medium-sized businesses, the on-site review of the books is capped: “Sous peine de nullité de l’imposition, la vérification sur place des livres ou documents comptables ne peut s’étendre sur une durée supérieure à trois mois en ce qui concerne :” followed by the categories of companies covered by the cap. If the inspector overstays that three-month limit, the resulting assessment can be annulled. The same article extends the cap to six months only where serious irregularities deprive the accounts of all probative value, and it excludes from the count the time spent reviewing your replies after the fieldwork ends. When you are abroad, diarise the date of the first on-site visit yourself, because neither the inspector nor your accountant will necessarily do it for you (Article L52 of the tax procedure code).

B. The Proposed Reassessment: Figures, Penalties and the Documents the Office Used Against You

The fieldwork ends with the document that decides everything: the proposition de rectification, the proposed reassessment, which sets out each adjustment, its legal basis and its amount. The procedure code imposes a strict duty of reasoning: “L’administration adresse au contribuable une proposition de rectification qui doit être motivée de manière à lui permettre de formuler ses observations ou de faire connaître son acceptation.” If the reasoning is so thin that you cannot understand what you are accused of and reply usefully, the reassessment is vulnerable. Read the proposal line by line with your counsel the week it arrives, because your reply deadline is short. The general rule is thirty days from receipt: “le délai accordé aux contribuables pour répondre aux demandes de renseignements, de justifications ou d’éclaircissements et, d’une manière générale, à toute notification émanant d’un agent de l’administration des impôts est fixé à trente jours à compter de la réception de cette notification.” And the code offers one extension: “Sur demande du contribuable reçue par l’administration avant l’expiration du délai mentionné à l’article L. 11 , ce délai est prorogé de trente jours.” Ask for those extra thirty days in writing before the first deadline expires, even if you think your reply is nearly ready. From abroad, post, translation and time zones eat days faster than you expect (Article L57 of the tax procedure code; Article L11 of the tax procedure code).

Before you draft a single observation, check the figures box. The administration must state, for each head of reassessment, the exact amount of tax and penalties claimed: the code requires it to indicate “le montant des droits, taxes et pénalités résultant de ces rectifications” in the proposal itself, before you present your observations or accept the adjustments. A proposal that announces principles without numbers, or that lumps several years into one global sum, is defective. Then verify the method. If the inspector considered your accounts unreliable and rejected them, the rejet de comptabilité, he may rebuild your turnover from external clues, a reconstitution de chiffre d’affaires, for example from purchases, staff numbers or industry ratios. That reconstruction must be coherent year by year and must use realistic inputs. In the Paris hair-salon case mentioned above, the company attacked the reconstruction method, the average price of services and the quantities of towels and shampoo used to estimate revenue, which shows the level of detail at which these methods can and should be fought (Article L48 of the tax procedure code).

Pay special attention to any document that did not come from your own files. Where the administration relied on information obtained from third parties, including foreign tax authorities under international assistance, it must show its hand. The Lyon administrative court of appeal recalled the rule, set out in article L76 B of the procedure code, in a 14 October 2021 ruling, case number 19LY02326, concerning documents sent by the German and Romanian authorities: “L’administration est tenue d’informer le contribuable de la teneur et de l’origine des renseignements et documents obtenus de tiers sur lesquels elle s’est fondée pour établir l’imposition faisant l’objet de la proposition prévue au premier alinéa de l’article L. 57 ou de la notification prévue à l’article L. 76. Elle communique, avant la mise en recouvrement, une copie des documents susmentionnés au contribuable qui en fait la demande”. For a French subsidiary of a foreign group, this is a routine battleground: information about your parent company, your foreign suppliers or your cross-border invoices may have travelled through official channels, and you are entitled to see exactly what the inspector saw. Always request those third-party documents in writing as soon as the proposal cites them (Lyon administrative court of appeal, 14 October 2021, no. 19LY02326).

Then come the penalties, which often exceed the tax itself. First, late interest runs on almost every reassessment: “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.” The rate is fixed by the code: “Le taux de l’intérêt de retard est de 0,20 % par mois.” That is 2.4% per year, applied month by month from the date the tax should have been paid, and it cannot be negotiated down. Second, the code punishes intentional breaches with surcharges computed on the additional tax: “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 ;” The same article raises the surcharge to 80% for abuse of law or fraud schemes. Third, returns filed late attract their own scale, starting at “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” and rising to “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”. For a company run from abroad, late filing is the classic trap: the French calendar of returns and payments keeps running whether or not you received the reminder, so calendar every deadline in our guide to French corporate tax at 25% and its advance payments alongside this audit defence (Article 1727 of the general tax code; Article 1729 of the general tax code; Article 1728 of the general tax code).

There is, however, one moment when honesty pays immediately. During the audit, before any proposal is sent, you may ask for the spontaneous regularisation procedure, which covers mistakes made in good faith in returns filed on time. The tax authority describes it as follows: a statutory scheme for the spontaneous correction, during a book audit, of good-faith mistakes found in returns that were filed on time The reward is a reduced late-interest rate: a late-interest rate cut to 70% of the standard rate If the inspector has found a genuine error and you know that contesting it would fail, regularising on the spot cuts the interest by nearly a third and usually avoids the deliberate-fault surcharge. Discuss this option with your counsel before the proposal arrives, because once it is sent, the door closes.

II. Challenge the Reassessment and the Penalties From Abroad: Appeals, Deadlines and Getting the Money Back

A. Fight Inside the Tax Office First: Line Manager, Interlocutor and the Advisory Commission

Do not go to court straight away. The French system expects you to fight inside the tax office first, and it gives you two successive levels of internal appeal plus an independent advisory opinion. The tax authority’s own guidance states the principle clearly: if you disagree, you may turn first to the inspector’s line manager and then to the Interlocutor, during the audit and when it closes The first level is the inspector’s line manager, the supérieur hiérarchique, whom you can ask to meet during the audit if the fieldwork goes wrong, or after the administration confirms the adjustments in its reply to your observations. That meeting is not a formality: the manager can overrule the inspector, drop an adjustment or reduce a penalty, and everything you say goes on the record for the rest of the procedure. The second level is the Interlocuteur, a senior official specially designated by the director in charge, whom you can normally approach only after the meeting with the line manager if disagreement persists. There is one shortcut worth knowing: you may go straight to the Interlocuteur without seeing the line manager first where that manager has personally signed a proposal carrying penalties that rule out good faith Where the proposal carries bad-faith penalties validated by the manager’s own signature, you may go straight to the Interlocutor. From abroad, both meetings can be prepared entirely by your counsel, who attends with a written speaking note and leaves a dated memorandum after each one.

Use these internal remedies early, because courts notice when you skip them. Remember the Paris ruling of 17 July 2023, case number 22PA02929: the company complained both of a missing oral debate and of being deprived of the safeguard allowing it to refer to the departmental interlocutor, and the court examined each complaint against the file before rejecting the debate argument, noting that the proposal itself proved that meetings and contradictory exchanges had taken place. The practical message is that internal guarantees work in both directions: they protect you when the administration forgets them, and they protect the assessment when you forget to use them. File every referral in writing, keep proof of dispatch, and never let a deadline pass assuming that silence will preserve your rights.

If disagreement persists after the internal appeals, you can ask for an outside opinion before going to court. The procedure code provides: “Lorsque le désaccord persiste sur les rectifications notifiées, l’administration, si le contribuable le demande, soumet le litige à l’avis soit de la commission des impôts directs et des taxes sur le chiffre d’affaires prévue à l’article 1651 du code général des impôts, soit de la Commission nationale des impôts directs et des taxes sur le chiffre d’affaires prévue à l’article 1651 H du même code”. That departmental or national commission, composed of administration representatives and taxpayer representatives with a magistrate in the chair, re-examines the facts and gives a reasoned opinion. The opinion is technically advisory, but in practice the tax office follows it in the large majority of cases, and the whole exercise forces both sides to clarify their positions before a judge ever sees the file. Note the trigger: the commission is seized only if you ask for it, so the request must be made expressly and in good time after the final confirmation of the adjustments. Alongside these remedies, remember that whenever the administration rejects your observations, its reply must itself be reasoned: “Lorsque l’administration rejette les observations du contribuable sa réponse doit également être motivée.” An unreasoned rejection letter is itself a procedural flaw you can raise later, so keep every letter the office sends you after your reply (Article L59 of the tax procedure code; Article L57 of the tax procedure code).

B. Take the Case to the Administrative Judge From Abroad: Formal Claim, Court Deadlines and Practical Moves

When the internal route has not resolved the dispute, the dispute moves to court, but through a mandatory doorway: the prior formal claim, the réclamation contentieuse, addressed to the tax office. The procedure code defines its scope generously: “Les réclamations relatives aux impôts, contributions, droits, taxes, redevances, soultes et pénalités de toute nature, établis ou recouvrés par les agents de l’administration, relèvent de la juridiction contentieuse lorsqu’elles tendent à obtenir soit la réparation d’erreurs commises dans l’assiette ou le calcul des impositions, soit le bénéfice d’un droit résultant d’une disposition législative ou réglementaire.” In other words, any error in the base or the computation of the tax, and any right granted by a statute or regulation, can be raised this way, including the penalties. You cannot skip this step and go directly to the tribunal: a court petition filed without a prior claim is inadmissible (Article L190 of the tax procedure code).

The claim has a strict time limit, and it is longer than most foreign directors expect, which is both good and dangerous news. The rule is: “Pour être recevables, les réclamations relatives aux impôts autres que les impôts directs locaux et les taxes annexes à ces impôts, doivent être présentées à l’administration au plus tard le 31 décembre de la deuxième année suivant celle” of the collection of the tax, its payment, or the event giving rise to the claim. Concretely, a reassessment collected in 2026 can generally be challenged until 31 December 2028. Do not treat that comfort as a reason to wait: evidence goes stale, accountants change, and the inspector’s version hardens with time. File the claim as soon as the collection notice arrives, state precisely which adjustments you contest and the amount of relief you seek, and send it by a traceable channel. From abroad, the secure messaging of your company’s professional tax account, or a registered letter with acknowledgement of receipt handled by your counsel, both work (Article R*196-1 of the tax procedure code).

The single most useful sentence to include in that claim concerns payment. French law lets you hold back the contested part of the bill while you fight: “Le contribuable qui conteste le bien-fondé ou le montant des impositions mises à sa charge est autorisé, s’il en a expressément formulé la demande dans sa réclamation et précisé le montant ou les bases du dégrèvement auquel il estime avoir droit, à différer le paiement de la partie contestée de ces impositions et des pénalités y afférentes.” Two conditions, both mandatory: the request must be express, and it must specify the amount or the basis of the relief claimed. A vague letter saying you disagree with everything does not suspend anything. Where the claim covers the whole reassessment, that sentence alone can freeze several hundred thousand euros of collection. The accountant may then ask for guarantees, such as a bank guarantee or a mortgage, to secure the suspended amount. If you consider the guarantees demanded excessive, the law gives you a fast-track judge: “celui-ci peut, dans les quinze jours de la réception de la décision du comptable, porter la contestation, par simple demande écrite, devant le juge du référé administratif”, but that application “n’est recevable que si le redevable a consigné auprès du comptable, à un compte d’attente, une somme égale au dixième des impôts contestés.” In practice, arrange the guarantee discussion with your French bank early, because a foreign parent guarantee is often refused and the fifteen-day clock runs fast. If you want a Paris lawyer to sign the claim, negotiate the guarantees and attend the hearings, you can call Maître Reda Kohen on +33 6 46 60 58 22; the first telephone review is billed 80 EUR incl. VAT (Article L277 of the tax procedure code; Article L279 of the tax procedure code).

If the administration rejects the claim, or stays silent long enough that the silence counts as a rejection, you can petition the tribunal administratif, the first-level administrative court of the place where the tax was assessed, and then, on appeal, the cour administrative d’appel. You do not need to travel: your lawyer files, pleads and receives the judgment for you, and most cases of this type are decided on the papers after a public hearing your counsel attends alone. Build the court file around the procedural flaws identified during the audit, because judges annul reassessments on procedure alone without ever discussing the figures: a notice missing the right to counsel, an on-site review running past three months, a proposal without amounts, third-party documents never disclosed, or an unreasoned rejection of your observations. Each of those defects, documented in this guide with the exact statutory wording, can wipe out the whole reassessment and its 40% surcharges in one stroke. The official service-public guide to challenging the tax administration and the tax authority’s own page on remedies during an audit summarise the same ladder of remedies, and they are worth bookmarking next to the statutes: article L47, article L13, article L52, article L57, article L48, article L59, article L190, article R*196-1, article L11, article L277, article 1727, article 1729 of the general tax code, the Paris administrative court of appeal ruling 22PA02929 of 17 July 2023 and the Lyon administrative court of appeal ruling 19LY02326 of 14 October 2021.

Conclusion

A French tax audit run from abroad is won or lost on three reflexes. First, treat the audit notice as the starting gun: check the years, appoint your counsel in writing, and demand the charter of rights before the inspector opens a single ledger. Second, calendar every deadline yourself, the thirty days to answer the proposed reassessment with its thirty-day extension, the express request to suspend payment in your formal claim, and the 31 December of the second year that closes the door for good. Third, escalate early through the line manager, the interlocutor and the advisory commission, while building from day one the procedural file a judge needs: meeting notes proving the debate happened or did not, the amounts box in the proposal, the third-party documents you asked to see, and the reasons given for rejecting your observations. The French procedure gives a well-advised foreign director as many weapons as a Paris-based one, and several reassessments collapse each year on a missing sentence in the notice or a missing figure in the proposal. Keep your electronic accounting file clean, answer everything in writing, and make the administration earn every euro it claims.
