You live in London, New York, Dubai or Singapore. Your French company — usually a SAS (société par actions simplifiée, the flexible joint-stock company foreigners prefer) or a SARL (société à responsabilité limitée, the private limited company) — runs in Paris, Lyon or Bordeaux with an accountant, a registered office and a Kbis (the official company identity extract issued by the greffe, the commercial court registry). One morning your accountant forwards an email: the SIE (Service des impôts des entreprises, the corporate tax office of the DGFIP, the French tax administration) announces a vérification de comptabilité (a full on-site audit of your accounts). You panic: do you have to fly to France, hand over everything immediately, and pay whatever amount the auditor writes down? No. French tax audits follow a strict contradictory procedure set out in the LPF (Livre des procédures fiscales, the tax procedure code) and the CGI (Code général des impôts, the general tax code), with mandatory notices, a binding charter of rights, reasoned reassessment proposals, fixed answer deadlines and several levels of appeal that a foreign-based owner can activate by email, post and authorised representative. This guide explains, step by step, how a tax audit reaches you abroad, what happens inside your French premises, how the reassessment is notified, and how you challenge it — with the exact legal texts and court decisions that protect you, and the practical documents to prepare from abroad before the deadline expires.
I. Your French company receives a tax audit notice while you live abroad: what the administration must send and what happens on your premises
Everything starts with paper, not with a visit. French law forbids a surprise examination of your books: the auditor must announce the audit, identify the years concerned, tell you that you may be assisted by counsel, and give you the charter of the audited taxpayer. From abroad, your first job is therefore a documentary check, not a payment. Read the notice line by line, calendar the dates, appoint a representative in France, and verify that each guarantee was respected — because a missing mandatory statement can annul the whole reassessment.
A. The audit notice, the charter and the years under review: how to check that the procedure started lawfully from abroad
The founding rule is stated in Article L47 of the Livre des procédures fiscales: “une vérification de comptabilité ou un examen de comptabilité ne peut être engagé sans que le contribuable en ait été informé par l’envoi ou la remise d’un avis de vérification ou par l’envoi d’un avis d’examen de comptabilité”. In plain English for a foreign founder: no on-site audit of your French company may begin unless you were first informed by the sending or delivery of an audit notice. The same article adds the sentence that saves many foreign-owned companies: the notice must state “que le contribuable a la faculté de se faire assister par un conseil de son choix” — that you have the right to be assisted by counsel of your choice — failing which the procedure is void. Concretely, when your accountant forwards the avis de vérification, check three things the same day: does it list precisely the years and taxes under review, does it contain the counsel-assistance paragraph, and does it tell you where to find the charte des droits et obligations du contribuable vérifié (the charter of rights and obligations of the audited taxpayer, available on impots.gouv.fr and summarised in the official charter page of the DGFIP)? If any of these is missing, tell your French counsel immediately and in writing, because the Conseil d’État treats the charter as binding: in CE, 18 February 2025, n° 492413 (Valmer), the court recalls that “les dispositions contenues dans la charte sont opposables à l’administration” — the provisions of the charter can be invoked against the administration — and that officers must comply with charter rules guaranteeing taxpayer rights even when those rules have no equivalent in the codes. The administration publishes the detailed procedure in the BOI-CF-PGR-20-40 on guarantees during audits (BOFiP, the official tax bulletin), which your counsel should cite in correspondence.
Second, understand what the auditor chose: a vérification de comptabilité means the auditor comes to your French premises and examines books, invoices, contracts and software on site; an examen de comptabilité means a desk review conducted from the office on files you send, including the FEC (fichier des écritures comptables, the standardised electronic accounting file). The distinction matters from abroad because a desk review runs through deadlines and correspondence, while an on-site audit requires someone to open the door, provide a workspace and answer factual questions. In both cases, appoint without delay a person physically present in France — your expert-comptable (chartered accountant), your avocat (attorney), or an employee with a written power of attorney — and notify the auditor by email and registered letter that all correspondence, meeting invitations and draft conclusions must go through that representative with a copy to you. French auditors accept representation; what they do not accept is silence. An unannounced material check is possible only at the very start to record physical items or the existence of documents, and even then the notice and the charter must be handed over at the beginning of those observations, with the substantive examination starting only after a reasonable delay allowing you to arrange counsel. From abroad, use that delay: ask your accountant to freeze the relevant years in the software, export the FEC for each year under review, gather bank statements, sales and purchase ledgers, payroll journals (DSN, déclaration sociale nominative, the monthly payroll return sent to URSSAF, the social-security collection agency), VAT returns (CA3), corporate income tax returns (IS, impôt sur les sociétés) and the contracts behind exceptional entries such as management fees paid to your foreign parent, intercompany loans or transfers of activity. Do not rewrite history: never recreate invoices, never backdate minutes, never delete emails. The auditor compares coherence — turnover declared for VAT versus turnover booked for corporate tax versus cash movements — and reconstructed files are treated as opposition to control, which leads to unilateral assessment.
Third, calendar the outer time limits that frame the whole operation. The administration cannot audit you forever: Article L169 of the Livre des procédures fiscales provides that “Pour l’impôt sur le revenu et l’impôt sur les sociétés, le droit de reprise de l’administration des impôts s’exerce jusqu’à la fin de la troisième année qui suit celle au titre de laquelle l’imposition est due” — for income tax and corporate tax, the administration may reassess until the end of the third year following the year for which tax is due. For a 2023 corporate year closed on 31 December 2023, the standard deadline therefore runs to 31 December 2026, extended to ten years only for hidden activity. Ask your counsel to verify, for each tax and each year listed on the notice, whether the reassessment right was still open on the day the notice was sent, and whether any interruption (a prior reassessment proposal, a court filing) extended it. Keep also the protective rule of Article L51 of the Livre des procédures fiscales: “Lorsque la vérification de comptabilité ou l’examen de comptabilité, pour une période déterminée, au regard d’un impôt ou d’une taxe ou d’un groupe d’impôts ou de taxes, est achevé, l’administration ne peut procéder à une vérification de comptabilité” on the same records for the same taxes and period. A completed audit for 2022 corporate tax cannot be restarted for the same tax and period except in the narrow statutory exceptions (audit limited to specific transactions, turnover-tax cases, fraud, or specific information requests). If your company was already audited two years ago and the new notice covers the same ground, raise Article L51 in your first reply.
B. The on-site verification, the three-month limit and the ban on a second audit: what the auditor can do inside your French company
Once the notice period has run, the auditor visits your French establishment — your siège social (registered office), your branch premises, or your accountant’s office if the books are kept there. For a founder living abroad, the critical point is that the auditor examines, but does not manage: the auditor may consult all books and documents, take copies, ask for justifications, test the accounting software and note inconsistencies, but may not remove original documents without your agreement and may not conduct the audit from home for months without coming on site. Small companies enjoy a powerful time shield in Article L52 of the Livre des procédures fiscales: “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” for industrial and commercial businesses below the turnover thresholds and for small farming businesses. If your French subsidiary is a small operating company under the thresholds, count the days between the first on-site visit and the last: beyond three months of on-site presence, the resulting assessment is void, unless the overrun results from your own delays or from specific statutory extensions. Larger companies are not protected by the three-month cap, but they remain protected by the general requirement of a genuine contradictory debate: the auditor must present findings progressively, hold a closing meeting (réunion de synthèse) and let you respond before anything is notified. Instruct your representative to attend every meeting, to take minutes, to ask for the auditor’s preliminary concerns in writing, and to send observations by email the same week. A founder who learns of the auditor’s theory only upon receiving the reassessment proposal has lost the most valuable phase — the informal correction phase where a missing contract, a translation or a bank proof can still close the issue.
Document discipline decides the outcome more than rhetoric. French auditors reason from the FEC and the supporting documents: every sale must tie to an invoice and a bank receipt, every purchase to an invoice and a payment, every payroll entry to a DSN and a URSSAF statement, every intercompany charge to a signed agreement, transfer-pricing documentation where required, and proof of actual service. Foreign founders are typically reassessed on four recurring items: management fees invoiced by the foreign parent without proof of service rendered to the French company, cash advances or shareholder current-account movements (compte courant d’associé, the flexible loan account between a company and its shareholder) reclassified as hidden distributions, VAT deducted on invoices that do not meet French invoicing requirements, and research tax credit (CIR, crédit d’impôt recherche) claimed without time sheets and project reports. The Conseil d’État decision in CE, 17 June 2021, n° 435357 (Date), concerning research credits challenged after a vérification de comptabilité of the company Développement et Applications des Techniques de l’Energie, illustrates how the court controls procedural guarantees step by step, including access to senior reviewers, before examining the substance of the credits. Prepare from abroad a bundle per risk item: the signed intercompany agreement with its appendices and renewal letters, the emails and reports proving the service, the time records, the bank statements showing payment, the French translation of any English-language contract, and the Kbis, articles of association (statuts) and RBE (registre des bénéficiaires effectifs, the beneficial-owner register) proving who ordered what. Send copies, keep originals, number the exhibits and keep proof of dispatch. If the auditor requests information you cannot produce within days — foreign bank archives, parent-company ledgers — reply in writing before the deadline, explain the practical obstacle, propose a precise date, and ask for an extension. Courts distinguish a taxpayer who cooperates with difficulty from one who obstructs: only the second faces taxation d’office (unilateral assessment) and the heaviest penalties.
Two behaviours must be avoided absolutely. First, refusing entry, hiding software access or ignoring information requests can be qualified as opposition à contrôle fiscal (opposition to tax audit), which authorises the administration to assess tax unilaterally and applies severe penalties under Article 1728 of the Code général des impôts, since “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” of increased charges on the duties assessed. Second, signing an acceptance you do not understand during the closing meeting binds you: an express acceptance of the proposed reassessments limits later challenge to narrow grounds. Your representative should therefore never sign acceptance on the spot; the correct sentence is that you take note, will examine the draft with counsel and will answer within the statutory deadline after receiving the formal proposal. From abroad, confirm that instruction in writing to your own team so that politeness toward the auditor does not become a waiver.
II. Your French company receives a reassessment while you live abroad: how to answer within the deadline and challenge the bill
The audit ends with paper again: a proposition de rectification (reassessment proposal) explaining, year by year and tax by tax, what the administration wants to change, why, and how much principal, late interest and penalties it claims. This document is the most important letter your French company will receive this year. It opens a thirty-day window — extendable once by thirty days on request — during which a precise, reasoned, exhibit-backed answer can reduce or cancel the bill. After that, a chain of remedies runs from the senior reviewer inside the tax office to the tax commission, the formal claim, and the administrative court, with the possibility of suspending enforced collection while you litigate. Each step has its own deadline and its own form; missing one does not always kill the case, but it always makes victory harder and more expensive.
A. The reasoned reassessment proposal and the 30-day answer: how to respond from abroad without losing your rights
The general procedure is the rectification contradictoire (adversarial reassessment procedure) defined in Article L55 of the Livre des procédures fiscales for cases where the administration finds “une insuffisance, une inexactitude, une omission ou une dissimulation dans les éléments servant de base au calcul des impôts, droits, taxes, redevances ou sommes quelconques dues en vertu du code général des impôts” — an insufficiency, inaccuracy, omission or concealment in the basis of taxes due under the general tax code. Within that procedure, Article L57 of the Livre des procédures fiscales imposes the key guarantee: “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.” The administration must send a reassessment proposal reasoned well enough to let you comment or accept. Complementing this, Article L48 of the Livre des procédures fiscales requires that “l’administration doit indiquer, avant que le contribuable présente ses observations ou accepte les rehaussements proposés, dans la proposition prévue au premier alinéa de l’article L. 57” the amount of duties, taxes and penalties resulting from the reassessments. In practice, your proposal must therefore contain, for each year and each tax: the legal basis, the facts found, the reasoning linking facts to the additional amount, and the quantified principal, late interest (intérêt de retard, currently 0.20 percent per month) and penalties. The Conseil d’État enforces this strictly: in CE, 26 July 2018, n° 408480, the court examined a reassessment proposal that had added 1,187,556 euros of partnership profits to an individual’s income and verified whether the administration had sufficiently explained the gap between the admitted undeclared amount and the final taxable base, including the 1.25 multiplier, before deciding on discharge. When you receive the proposal abroad, apply the same test with your counsel: for each reassessment, can you identify the invoice, the year, the legal article and the arithmetic? If the motivation is generic, contradictory or purely assertive, that defect must be raised from your first observations, because an insufficiently reasoned proposal can lead to full discharge of the corresponding tax.
Your answer deadline is short and runs from receipt. The standard period is thirty days from receipt of the proposal to send observations or acceptance; on your request received before expiry, the period is extended by thirty days. From abroad, act in the first week: confirm receipt in writing, request the thirty-day extension systematically to gain time for translations and foreign evidence, and organise the response point by point. A strong observations letter follows the auditor’s own numbering, concedes what is indefensible (a bookkeeping error, a missing invoice) to gain credibility, contests each remaining item with facts, law and exhibits, quantifies an alternative figure where possible, and closes with an explicit request — cancellation of specified items, reduction to a specified amount, or referral to the commission where relevant. Attach numbered exhibits with an index, reference each exhibit in the text, and send by tracked means to the address stated on the proposal while keeping proof of dispatch and receipt. If the administration later modifies the reassessments to take your observations into account, it must inform you of the new amounts before establishing them. Never let the deadline pass in silence: without observations, the reassessment becomes final on the administration’s terms and later remedies start from a much weaker position. Late interest accrues month by month until payment or discharge, and penalties scale with behaviour — 10 percent for late filing without formal notice or within thirty days of a notice, 40 percent beyond, up to 80 percent for abuse of law or fraud — under Article 1728 of the Code général des impôts and the related penalty articles your counsel will cite precisely. Paying part of the claim to stop interest while contesting the rest is possible through the formal claim and suspension procedure described below; your counsel will calibrate that choice against cash flow and the strength of each item.
Practical management from abroad follows a checklist. First, centralise everything with your French counsel: the audit notice, the charter, the FEC files, the meeting notes, the proposal and its annexes, and every exchange with the auditor. Second, decide who signs: observations should be signed by the legal representative (président of a SAS, gérant of a SARL) or by counsel with a written power of attorney, with the Kbis proving authority and the RBE available if ownership is questioned. Third, line up foreign evidence early: parent-company board minutes approving the service agreement, group transfer-pricing policy, employment contracts of staff who performed the services, travel records, bank proofs of payment from the French account (relevé de compte), and sworn translations where the auditor cannot read English. Fourth, quantify: rebuild the alternative computation for each year (corrected turnover, deductible charges, VAT base, CIR base) so the reviewer and later the judge can substitute your figure without redoing the audit. Fifth, keep the company alive administratively during the dispute: continue filing current VAT, corporate tax instalments (acomptes d’IS), payroll DSN and CFE (cotisation foncière des entreprises, the local business tax) on time, because fresh late-filing penalties weaken any negotiation and can trigger aggressive collection. The reassessment concerns past years; do not create new ones.
B. The departmental reviewer, the tax commission and the court: how to escalate, suspend payment and win from abroad
If the auditor maintains the reassessments after your observations, French procedure offers a ladder of internal review before any court. The charter, which the Conseil d’État holds binding, promises a second look inside the administration. In CE, 18 February 2025, n° 492413 (Valmer), the court quotes the charter given to the company: “Si le vérificateur a maintenu totalement ou partiellement les redressements envisagés, des éclaircissements supplémentaires peuvent vous être fournis si nécessaire par l’inspecteur divisionnaire ou principal. Si après ces contacts des divergences importantes subsistent, vous pouvez faire appel à l’interlocuteur spécialement désigné par le directeur dont dépend le vérificateur” — if the auditor maintains the adjustments, further explanations may be provided by the divisional inspector, and if significant differences remain, you may appeal to the contact person specially designated by the director. In CE, 17 June 2021, n° 435357 (Date), the court quotes the equivalent wording: “Si le vérificateur a maintenu totalement ou partiellement les redressements envisagés, des éclaircissements supplémentaires peuvent vous être fournis si nécessaire par l’inspecteur principal” and “vous pouvez faire appel à l’interlocuteur départemental ou régional qui est un fonctionnaire de rang élevé spécialement désigné par le directeur dont dépend le vérificateur” — you may appeal to the departmental or regional reviewer, a senior officer specially designated. From abroad, request both levels in writing immediately after the auditor’s reply to your observations: first the hierarchical appeal to the supérieur hiérarchique (the auditor’s superior), then the interlocuteur départemental (the departmental reviewer). These meetings, held by phone or video with your counsel present in France, often resolve factual misunderstandings — a service actually rendered, a currency conversion, a credit note posted in the wrong year — without litigation. Present a short memorandum, the decisive exhibits only, and a quantified settlement proposal. The reviewers can abandon or reduce items; they cannot create new ones beyond the notified proposal.
For disputes about facts — valuation, deductible nature of a charge, reality of a service, accounting classification — you may also require referral to the commission des impôts directs et des taxes sur le chiffre d’affaires (the commission for direct taxes and turnover taxes), as provided in Article L59 of the Livre des procédures fiscales: “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” and the other listed bodies. Request the commission in your observations or promptly after, identifying precisely the items submitted; the commission hears both sides and issues an opinion that the administration usually follows on facts, though it remains an opinion, not a judgment. Legal questions — interpretation of a statute, validity of the procedure — go directly to the formal claim (réclamation contentieuse) after the assessment notice (avis de mise en recouvrement) is issued, then to the tribunal administratif (TA, the administrative court) within two months of the rejection or of the six-month silence, with appeal to the cour administrative d’appel (CAA) and cassation before the Conseil d’État (CE). The detailed claim procedure and payment-suspension mechanism are explained in the BOI-CF-PGR-30-25 on guarantees in reassessment procedures (BOFiP) and the BOI-CF-COM-10-10-10 on communication rights (BOFiP) for related information requests. Crucially, enforced collection can be suspended while you litigate: after receiving the collection notice, file a réclamation with an explicit request for sursis de paiement (suspension of payment), and if the administration demands guarantees (bank guarantee, mortgage, cash deposit), negotiate their form through counsel — a foreign parent guarantee is sometimes accepted where a French bank guarantee is disproportionate. Without a suspension request, the comptable public (public collection officer) may issue an ATD (avis à tiers détenteur, a third-party garnishment served on your French bank) and freeze the account; with a valid suspension, collection stops until the court decides, subject to the guarantees. From abroad, mandate your counsel to file the claim, track the six-month silence deadline, lodge the TA appeal, and monitor the BODACC (Bulletin officiel des annonces civiles et commerciales, the official gazette where insolvency and enforcement publications appear) and your bank for any collection step.
Choose litigation only on winnable grounds and plead them precisely. Procedural defects come first because they can annul without debating figures: missing counsel-assistance statement on the notice (Article L47), audit beyond the three-month on-site cap for small companies (Article L52), breach of a charter guarantee that the Conseil d’État has held binding (CE Valmer and CE Date above), insufficiently reasoned proposal (Article L57, CE 408480 above), reassessment after a completed audit on the same records (Article L51), or expiry of the three-year recovery period (Article L169). Substantive grounds come second: proof of the service behind management fees, arm’s-length character of intercompany pricing, corrected VAT arithmetic, or documented CIR hours. Quantify every alternative and ask the judge for partial discharge item by item, so that a strong item survives even if a weak one fails. Keep in mind that penalties require their own motivation and proportionality review: contest the legal qualification (simple late filing versus deliberate failure versus fraud), the factual evidence of intent, and the arithmetic. Throughout, keep your French company compliant and reachable: a company that files, pays current taxes, answers within deadlines and appears through counsel obtains suspensions, payment plans (délais de paiement) and negotiated guarantees far more easily than a company that disappears abroad. The administration audits records; it negotiates with people.
Conclusion
A French tax audit managed from abroad is won long before the court hearing, in the first ten days after the notice and the thirty days after the reassessment proposal. Check the notice against Article L47, secure the charter, appoint a representative in France, freeze and export the FEC, and calendar the three-year recovery period and the three-month on-site cap where it applies. Answer the reasoned proposal point by point with numbered exhibits, request the extension, then climb the review ladder — hierarchical superior, departmental reviewer, tax commission — before filing the formal claim with suspension of payment and, if needed, appealing to the administrative court. The Conseil d’État decisions on the binding charter and on reasoned proposals show that French judges annul reassessments when guarantees were ignored, but they expect the taxpayer to have raised each defect early and proved each figure. Organise that chain from abroad through one French counsel holding a complete file, and the distance becomes an administrative detail rather than a vulnerability.
