Appointing a statutory auditor is only half of the work for a foreign founder. The appointment must also be made by the right corporate body, supported by a coherent resolution, reported through the French business-formalities portal and reflected in the company’s National Register of Enterprises (RNE) record. If the filing is incomplete, the company may continue to operate with an appointment that cannot be proved easily to a bank, investor, tax auditor or contracting partner. A mismatch between the resolution, the filing and the company extract can also create avoidable questions about the auditor’s mandate.
In French company law, the statutory auditor is the commissaire aux comptes, abbreviated as “CAC”. The CAC is not the same professional as the expert-comptable, the accountant who may prepare accounts, payroll and tax returns. The RNE is the national register that centralises business-registration data. The Guichet unique is the online one-stop shop used to submit company formalities, while the greffe is the court registry handling the company’s registration. A Kbis is the official extract showing the registered details of a company.
This article answers a narrower question than a general guide to CAC thresholds: what should a foreign founder do after the appointment decision has been taken? It covers the legal validity of the decision, the identity and address information to prepare, the RNE and INPI filing route, the legal notice, foreign-signatory issues, privacy, Kbis verification and remedies when the registry rejects or fails to update the filing.
For the wider choice of French vehicle and first compliance steps, see the firm’s French company formation and corporate structuring practice. The filing described below should be treated as a documented corporate project, not as a box to tick at the end of the financial year.
I. What must a foreign founder confirm before filing a French statutory auditor appointment?
A. Was the CAC appointed by the right body and for the right mandate?
The first question is not which button to press on the INPI portal. It is whether the company has a decision that can legally support the filing. The French term “INPI” refers to the Institut national de la propriété industrielle, the National Institute of Industrial Property. INPI operates the technical platform, but the platform does not replace the company’s articles, the Code de commerce or the powers of the competent corporate body. A successful upload cannot cure a resolution adopted by an unauthorised person or a vote taken without the required notice.
Under Article L. 821-40 of the Code de commerce, statutory auditors are designated according to the procedure provided by that article. In a company with an ordinary general meeting, the ordinary general meeting normally makes the appointment; in another structure, the equivalent competent body must act. “Ordinary general meeting” is the English description of the assemblée générale ordinaire, often abbreviated as AGO. The company should read its articles first, because the articles may identify the body, voting rules, quorum, majority and method for decisions by a one-person shareholder or a simplified joint-stock company.
The resolution should identify the CAC precisely. It should give the individual auditor’s full name, professional address and registration details, or the exact legal name and registered office of the audit company. If a substitute auditor is required, the resolution should identify that substitute in the same way. Article L. 821-40 requires a substitute in the circumstances stated by the Code when the appointed CAC is an individual or a one-person audit company. A foreign parent should not write only “the group auditor” or “the audit firm recommended by the parent”. The registry and the company’s records need an identifiable legal person.
The resolution should also state whether the appointment is mandatory, voluntary, an initial appointment, a renewal or a replacement. The reason is practical as well as legal. It allows the auditor, the registry and the shareholders to understand which duration rules apply. The board or shareholder decision should attach or refer to the written acceptance of the auditor, the calculation showing the legal trigger and, where relevant, the group analysis. The minutes should not describe an audit appointment as a simple accounting engagement.
The ordinary statutory term is six financial years. Article L. 821-44 of the Code de commerce provides that the CAC is appointed for a mandate of six financial years and that the functions end after the meeting deciding on the accounts for the sixth year. The minutes should therefore state the first and last financial years covered. If the company is replacing an auditor, the new appointment usually runs only until the predecessor’s mandate would have expired. A foreign founder should obtain the predecessor’s appointment date and end date before drafting the new resolution.
A shorter term may be available in the situations provided by law. Article L. 821-46 allows a company, in the categories it covers, to limit the mandate to three financial years. The choice must be made clearly in the corporate decision. A three-year engagement letter signed with an accountant does not, by itself, create a three-year statutory mandate. The corporate resolution and the statutory basis must match the intended duration.
The agenda is a separate risk. A foreign shareholder may have agreed the appointment informally with an auditor and expect the chair to add it to the meeting at the last moment. That approach is unsafe. In Cass. com., 14 February 2018, no. 15-16.525, the Court of Cassation held, in the context of a French SARL, that the question of appointing the CAC “doit être inscrite à l’ordre du jour”. In English, the question must be placed on the agenda. The notice, draft resolution and adopted minutes should name the same appointment.
The 2018 decision is especially useful for a foreign founder because cross-border corporate groups often prepare board materials in one jurisdiction and shareholder notices in another. A parent’s internal approval is not necessarily the French subsidiary’s shareholder resolution. The French entity should preserve the notice, proof of dispatch, agenda, attendance sheet or written-decision evidence, voting record and signed minutes. If a legal representative signs for a foreign corporate shareholder, the file should show that representative’s authority under the parent’s law and internal governance documents.
The legal trigger should also be recorded even when the filing concerns the appointment rather than the thresholds. The familiar two-out-of-three test compares balance-sheet total, turnover before value added tax and average employees. For a stand-alone company, the current ordinary thresholds are set out in Article D. 221-5 of the Code de commerce: €5 million of balance-sheet total, €10 million of turnover excluding VAT and 50 average employees. A company does not become subject to an audit merely because a foreign parent wants a prestigious auditor or because a bank requests comfort. The file should say whether the appointment is mandatory or voluntary.
Group rules may produce a different answer. Article L. 821-43 of the Code de commerce addresses a person or entity controlling one or more companies and the appointment obligations that can arise from the group. The implementing rule in Article D. 821-172 uses €2.5 million of balance-sheet total, €5 million of turnover before VAT and 25 average employees for the controlled-company situation described by the Code. A foreign-owned French SAS can therefore need a CAC even where its local accounts look small when read without the group chart.
The founder should retain two worksheets: one for the French company’s own figures and one for the group or controlled-company analysis. The second worksheet should identify direct and indirect control, voting rights, controlled entities, the relevant financial years, eliminations and the source of each figure. If consolidated accounts are involved, check Article L. 821-41, which contains the rule requiring two independent auditors in the consolidated-account situations covered by the Code. A simple threshold table is not enough when the group structure is international.
These calculations are not a substitute for legal advice on the company’s particular form. An SAS, Société par Actions Simplifiée or simplified joint-stock company, may organise shareholder decisions differently from an SARL, Société à Responsabilité Limitée or private limited company. An SASU, a one-person SAS, may use a sole shareholder decision. An EURL, a one-person SARL, may use a sole shareholder decision under its own rules. The filing must reproduce the company’s actual governance path, not a generic template prepared for another entity.
Finally, check whether the selected auditor can accept the mandate under French independence and professional rules. A foreign parent’s home-country accountant may assist the group, but that does not automatically make the person a French CAC. The appointment document should identify the French statutory-auditor status relied on and the audit company’s relevant registration details. If the appointment is part of an international audit network, record which entity signs the French statutory report and which entities provide group-audit assistance.
B. Which identity, address and corporate documents belong in the RNE filing?
Once the corporate decision is validated, prepare the filing as a single evidence package. The RNE record must receive information that is consistent with the minutes, the acceptance letter and the auditor’s professional details. Article R. 123-54 of the Code de commerce is the key registration provision. The current text expressly addresses the information relating to a statutory auditor and provides: “Lorsque le commissaire aux comptes est une personne physique, son adresse professionnelle peut néanmoins être déclarée en lieu et place de son domicile.” The English meaning is that a natural-person CAC’s professional address may be filed instead of the home address.
The professional-address rule matters for privacy, but it does not permit an invented or incomplete address. Ask the auditor for the exact professional address to be used in the registry, including the street, postal code and town, and use the same version in the resolution, acceptance and Guichet unique form. If the auditor is an audit company, use its registered office and legal name. If a substitute auditor is part of the appointment, prepare the same information for the substitute rather than assuming that the registry will infer it.
There is a second privacy mechanism for personal addresses. Article R. 123-54-1 of the Code de commerce allows the legal representative of a registered legal person to request confidentiality for the personal address in the cases covered by that provision. The greffier, the court registry officer, has a period to process the request, and a redacted copy may be required where a document is filed in the RNE record. This mechanism concerns the personal data of the people covered by the article; it should not be confused with the company’s registered office or the CAC’s professional address.
The 2026 implementing rules also matter. Article 1 of Decree no. 2026-340 of 30 April 2026 inserted current wording on CAC information and the filing of documents containing limited identity and home-address data. It states, for example, that the formalities for depositing constitutive and amending acts may be satisfied by a copy in which natural-person identity and domicile information is limited to the information permitted by the Code. The practical result is that a foreign founder should prepare an unredacted working file for the company and the auditor, while uploading only the version required for public registration.
At a minimum, the document pack should contain the signed appointment resolution or sole-shareholder decision; the notice and proof that the appointment was placed on the agenda when a meeting was used; the CAC’s written acceptance; the CAC’s professional identification and registration information; the substitute’s information if applicable; the threshold and group analysis; and the company’s SIREN, the nine-digit French business identification number. Add the relevant power of attorney if a French lawyer, accountant or other mandataire submits the form.
If a foreign legal person is the shareholder, add evidence of its existence and the signatory’s authority in the form requested by the receiving registry. Depending on the jurisdiction and document, that may require a certified copy, a sworn French translation, legalisation or an apostille. Do not upload a random parent-company extract simply because it was used for incorporation. The filing should explain the chain of authority from the foreign shareholder to the person who signed the French appointment.
Do not amend the articles of association unless the appointment or the company’s governance actually requires it. Many CAC appointments do not change the articles. Uploading an unnecessary amended version creates another potential inconsistency, particularly where the English translation and the French version have different dates or signatories. If an amended article is necessary, identify the exact article changed and use the same effective date in the minutes, the legal notice and the Guichet unique form.
The company should also prepare the legal-notice evidence. Service-Public explains that a legal notice is required for the appointment or termination of a statutory auditor and provides a current reference price for the notice. See Service-Public’s page on legal notices for companies. The notice is not a replacement for the RNE filing. It is a separate publicity step whose wording should identify the company, the decision date and the appointed or departing auditor consistently with the corporate minutes.
A foreign founder should keep a short “consistency table” before submission. The first column should list the company name, SIREN, registered office and legal form. The second should list the CAC’s name or legal name, professional address, registration information and mandate dates. The third should show the same fields in the signed resolution, acceptance, legal notice and online form. A fourth column can record the uploaded file name. This simple table catches the most common defects: a missing substitute, an old registered office, a different spelling of a person’s name, or an end date copied from a group engagement letter.
The company should not treat the Kbis as the place where every audit detail will necessarily appear in the same format as the uploaded form. The Kbis is an extract of registry data, while the RNE and the company’s filing history contain the wider record. The objective is that the legal data is correctly registered and that the company can produce the underlying resolution, acceptance and receipt. If the auditor’s information is absent from a public extract, verify the RNE history and the registry’s response before assuming the appointment is not recorded.
II. How should a foreign founder file, verify and correct the appointment through INPI?
A. What is the practical INPI and Guichet unique filing sequence?
The filing normally begins as a modification formalité for an existing company, not as a new incorporation. The French word formalité means the administrative filing submitted to update the registered record. On the official portal, identify the company by its SIREN, check the prefilled identity and registered-office data, select the modification that corresponds to the appointment and enter the effective date and reason. The portal’s workflow is described on the official business-formalities page for entering a filing. A mandataire can submit for the company if the authority document is included.
Choose the role carefully. The official portal’s information on management and representation asks for the role “Commissaire aux comptes titulaire”, meaning statutory auditor in the holder position, together with the person or entity’s identity and address. If a substitute is appointed, do not place the substitute in the holder field or leave the role ambiguous. Use the exact role offered by the form and compare the final summary with the corporate resolution before signing.
Attach the documents in a logical order: resolution first, acceptance second, legal-notice evidence, auditor identification, power of attorney and supporting threshold or group documents if requested. Use clear file names in English or French, but preserve the original French legal document as the authoritative version. A foreign founder can provide an English working translation for the parent’s internal approval, yet the filing should make clear which French document was signed and which translation is explanatory.
Sign and submit using the method accepted for the formalité. The official portal explains that a modification may require FranceConnect+, a government identity service, or an advanced electronic-signature certificate depending on the route used. See the portal’s signing instructions. A non-resident director may not be able to use the same identity method as a French resident. That is not a reason to abandon the filing: appoint a French mandataire with a carefully drafted power of attorney, or arrange the approved certificate route before the statutory deadline.
Record the submission number, date, payment receipt, uploaded file list and status messages. The portal’s confirmation is evidence of submission, not proof that the registry has accepted the appointment. The INPI itself explains that the formalities platform receives and transmits information but does not guarantee that uploaded documents are legally valid. The company must therefore monitor the filing and answer a request for correction. The relevant INPI explanation is available on the page for modifying a company.
Use the one-month period as an operational deadline for a registrable modification that affects the company’s registration data, while checking the event-specific rule for the exact appointment. The filing should not be postponed until the annual accounts are approved. The legal notice and RNE submission should be coordinated with the decision date. If the company is already outside the period, submit the correction promptly and explain the chronology rather than changing the decision date to make the file appear on time.
The filing may be rejected for a technical reason or for a legal-document reason. A technical rejection may concern an unreadable PDF, an unsupported signature, a missing page or a field left blank. A legal-document rejection may concern an absent acceptance, an incorrect role, a mismatch between the auditor and the resolution, an incomplete foreign power of attorney or a missing legal notice. Read the rejection message literally. Do not upload a new resolution with a different date merely to satisfy a request that can be answered with the existing signed document.
For a foreign corporate shareholder, the most frequent practical obstacle is authority. The registry may ask who authorised the individual who signed the French minutes, how that authority is evidenced and whether the foreign document is translated or legalised. Prepare a short authority chain: foreign parent’s constitutional document, board or shareholder authorisation if required, signatory’s identity and the power of attorney to the French filer. If the foreign parent has several directors, the file should state whether one signature is sufficient under the parent’s governing law.
After submission, monitor the status until the formalité is validated, rejected, suspended for missing information or otherwise completed. Save the registry messages with the filing receipt. If the company has an urgent bank, financing or tender deadline, provide the bank with the signed resolution and submission receipt while explaining that the updated Kbis is pending. Do not represent that the CAC is visible on the Kbis until the public record has been checked.
The legal calendar should include the auditor’s information request and the first audit timetable. A newly appointed CAC should receive the accounting opening balances, bank reconciliations, tax position, payroll records, related-party contracts and group reporting package. If the company uses a foreign accounting system, prepare a French chart-of-accounts bridge and a schedule translating the parent’s reporting categories into French statutory accounts. The appointment filing does not make the accounts auditable; it starts a relationship that must be organised before closing.
B. How can the company verify the Kbis, protect the mandate and respond to a dispute?
Verification should take place at three levels. First, check the portal status and download the accepted filing or formalité receipt. Second, obtain the updated Kbis or equivalent registry extract and compare the CAC information, company identity, registered office and effective date. Third, retain the complete RNE filing history and the signed corporate file. A company that has only an email saying “submitted” cannot easily prove what was filed, when it was filed or whether the registry accepted the appointment.
If the Kbis does not show the expected information, do not immediately file a second appointment. Compare the RNE result with the original form and the registry message. Some information may appear in the RNE or filing history rather than in the short extract; some appointment details may have been omitted because the form selected the wrong role; and some records may be awaiting processing. A duplicate filing can create two apparently competing appointments and make a later correction harder.
If the registry asks for a correction, answer through the same formalité when possible. Identify the original submission number, quote the exact request, attach only the corrected or missing document and explain the correction in one short note. For example, if the CAC’s professional address was entered as a home address, submit the signed acceptance showing the professional address and explain that the declaration is being aligned with Article R. 123-54. If the role was misclassified, correct the field and confirm that the corporate resolution has not changed.
Privacy corrections need special care. The company’s registered office is public corporate information. The CAC’s professional address may be used in place of a home address under Article R. 123-54 where the conditions apply. A request for confidentiality under Article R. 123-54-1 is a separate process. Keep a private copy of the full identity evidence and upload a redacted copy only when the rule and the portal require it. Do not redact the auditor’s name, professional identity or information necessary to identify the legal appointment.
The mandate itself should be placed in the company’s recurring governance calendar. Track the first financial year, sixth financial year, annual accounts meeting, auditor reports, substitute status, independence confirmations and any event that can require a replacement. Article L. 821-47 of the Code de commerce provides a court route when the competent corporate body fails to appoint a CAC in a situation where appointment is required: a member may ask the court to appoint one, and the mandate ends when the competent body makes the appointment. The official text is available at Article L. 821-47.
The company should also understand that a resignation does not automatically erase an existing mandate. In Cass. com., 10 May 2024, no. 22-16.158, the Court of Cassation held that “cette démission ne met pas fin au mandat”, meaning that the resignation did not itself end the mandate in the circumstances before the Court. The decision also addressed the application of changed thresholds to mandates already in progress. A foreign group should therefore obtain the predecessor’s formal resignation, the reason, the date and the replacement decision before treating a new filing as a clean start.
If the CAC moves office, changes legal form, merges into another audit company or becomes unavailable, the company should not wait for the next annual meeting to ask what must be done. Review the appointment term, the statutory replacement rules and the registry update. The current Code provisions on statutory-auditor implementation include rules concerning the auditor’s professional information and notifications. The practical file should record whether the change is a simple address update, a replacement for the remaining term or a new appointment requiring a corporate vote.
For a foreign parent, the audit file should be connected to the group’s legal calendar. A change in ultimate ownership, a new holding company, a merger, a change in voting rights or the creation of a new controlled subsidiary may change who must appoint and which thresholds apply. Refresh the group worksheet after each event. A CAC appointment that was correctly filed in January may still require a new analysis in June after an acquisition or restructuring.
There is also a banking and investor dimension. Banks often ask for a recent Kbis, the articles, the beneficial-owner information and proof of the authority of the person signing for the company. Investors may ask for the CAC’s acceptance and the latest audit report. Keep the signed resolution, filing receipt and Kbis together in a data room, with a short English explanation of the French terms. That explanation should define CAC, RNE, INPI, Kbis, greffe, AGO and SIREN rather than assuming that an overseas investor knows the French system.
Do not confuse the RNE update with the tax administration’s account formalities. The company may have to manage corporate income tax, VAT, payroll and social-contribution accounts separately. The French tax administration, the Direction générale des finances publiques or DGFiP, may request the auditor’s reports or financial information, but an update to the RNE does not automatically update every tax account. The director should use a separate checklist for the DGFiP, VAT and payroll portals, while keeping the CAC appointment evidence in the corporate file.
If a registry refusal appears legally wrong, preserve the full record before escalating: the original decision, notices, acceptance, legal notice, filing data, rejection message, document metadata and the company’s extract before and after the filing. Ask the registry to identify the missing legal basis. If the issue cannot be resolved administratively, the company can obtain advice on a correction, a new properly authorised decision or a court application. The correct response depends on whether the defect concerns the vote, the auditor’s eligibility, privacy, the online form or the registry’s processing.
The safest foreign-founder workflow is therefore sequential. Validate the appointment; prepare the identity and address data; obtain the legal notice; submit the modification through the Guichet unique; preserve the receipt; answer any request for correction; obtain the updated Kbis or RNE record; and schedule the audit work. Each step should refer to the same company name, SIREN, auditor, professional address, substitute and mandate dates. That consistency is more valuable than a rushed upload followed by a second filing that contradicts the first.
Conclusion
A French statutory-auditor appointment for a foreign-owned company is a corporate decision, a publicity step and a registry formalité at the same time. The foreign founder should first prove that the competent body voted on the appointment with the correct agenda, auditor identity, substitute and mandate. The file should then distinguish the CAC’s professional address from a personal home address, use the privacy rules carefully, document the foreign shareholder’s authority and include a coherent French-language evidence package.
The INPI and Guichet unique portal make submission easier, but they do not decide whether the resolution is valid or whether the group calculation is correct. The company should verify the RNE status, the Kbis, the filing history and the auditor’s mandate after submission. If the record is wrong, correct the original formalité with a precise explanation instead of creating a duplicate appointment. That discipline gives foreign founders a file that can be understood by the registry, the bank, the investor, the tax administration and the auditor.
