You live abroad and run your French business through a local subsidiary: a SAS (société par actions simplifiée, the flexible French joint-stock company) that buys from, sells to, or pays service fees to your foreign parent company. One morning, your French accountant forwards a letter from the French tax administration (the FTA, direction générale des finances publiques): during a tax audit (vérification de comptabilité), the auditor wants details of every transaction between your French subsidiary and the rest of the group, the method used to set the prices, and the documents proving those prices are arm’s length. You have thirty days to answer, and every missing page can cost money. This article explains what the auditor is allowed to do, what paperwork you must be able to produce from abroad, which penalties apply, and how to challenge a reassessment step by step.

I. The French Tax Office Can Tax Your Subsidiary on Profits It Believes Were Moved Abroad

The starting point is a single provision of the French General Tax Code (the CGI, code général des impôts): its article 57. It provides that profits indirectly transferred to related companies located outside France, whether by increasing or reducing purchase or sale prices or by any other means, are added back to the taxable results shown in the French company’s accounts. The official wording, verified on Légifrance (article 57 of the French General Tax Code), states: “les bénéfices indirectement transférés à ces dernières, soit par voie de majoration ou de diminution des prix d’achat ou de vente, soit par tout autre moyen, sont incorporés aux résultats accusés par les comptabilités.”

In practice, this covers every intra-group flow a foreign founder typically sets up: the French subsidiary buys finished goods from the parent at a price the auditor finds too high, sells French-made products to a foreign distributor of the group at a price the auditor finds too low, pays management fees, royalties for the brand, or interest on a shareholder loan granted by the parent. The auditor does not have to prove that you intended to avoid French tax. It is enough for the auditor to show that the price differs from what independent companies would have agreed. If you have not yet structured the French presence of your group, read our guide on creating a French subsidiary from abroad, registering it and funding it before designing the intra-group flows described below.

A. How the Auditor Proves the Transfer: Comparison With Independent Companies

Article 57 itself gives the administration its method. When it has no precise elements to compute the adjustment, the statute says: “A défaut d’éléments précis pour opérer les rectifications prévues aux premier, deuxième et troisième alinéas, les produits imposables sont déterminés par comparaison avec ceux des entreprises similaires exploitées normalement.” That sentence, taken from article 57 of the French General Tax Code, is the legal engine of almost every transfer pricing reassessment in France: the auditor compares your subsidiary’s prices or margins with those of similar companies operating normally, meaning companies with no dependency link.

The Conseil d’État, France’s highest administrative court, confirmed exactly how this presumption works in a decision of 4 October 2021 (8th and 3rd chambers combined, no. 443133, published on Légifrance: Conseil d’État, 4 October 2021, no. 443133). The court held: “lorsqu’elle constate que les prix facturés par une entreprise établie en France à une entreprise étrangère qui lui est liée – ou ceux qui lui sont facturés par cette entreprise étrangère -, sont inférieurs – ou supérieurs – à ceux pratiqués par des entreprises similaires exploitées normalement, c’est-à-dire dépourvues de liens de dépendance, l’administration doit être regardée comme établissant l’existence d’un avantage qu’elle est en droit de réintégrer dans les résultats de l’entreprise française, sauf pour celle-ci à justifier que cet avantage a eu pour elle des contreparties au moins équivalentes.”

Three consequences follow for a founder living abroad. First, once the comparison reveals a gap, the advantage is presumed and the burden shifts to your subsidiary: it must demonstrate that the apparent advantage was matched by at least equivalent counterparty benefits, such as guaranteed volumes, risks assumed for the group, or services genuinely received. Second, the administration may use modern financial methods, not only invoice-by-invoice price comparisons. In that same 2021 decision, the Conseil d’État accepted that “se fonder sur la comparaison d’un ratio financier pertinent de l’une ou l’autre entreprise, tel que le taux de marge sur ces transactions, avec celui d’entreprises similaires exploitées normalement, c’est-à-dire dépourvues de lien de dépendance.” (Conseil d’État, 4 October 2021, no. 443133) In the case decided that day, the auditor had applied the transactional net margin method, comparing the French company’s net margin ratio on the disputed transactions (negative 10.46 percent in 2009 and negative 21.87 percent in 2010) with the average ratio of eight independent companies in neighbouring activities (positive 2.33 percent and 2.62 percent). The court of appeal had been entitled to hold that this comparison established a presumption of profit transfer measured by the difference between the recorded revenue and the revenue that would have resulted from applying the average net margin rate of the comparable panel.

Third, comparability is fought on functions, assets and risks, not on labels. The leading illustration is the ST Dupont case decided by the Conseil d’État on 5 July 2023 (8th and 3rd chambers combined, no. 464928: Conseil d’État, 5 July 2023, no. 464928). The French manufacturer sold finished luxury products to its Hong Kong distribution subsidiary, and the auditor compared those prices with sales of the same products to an independent South Korean company and to a network of duty-free shops in South-East Asia. The company argued that its Hong Kong subsidiary acted as both wholesaler and retailer while the Korean company was only a wholesaler. The court of appeal rejected the objection because the company produced no element allowing the nature and cost of the alleged functional differences, considering the assets used and the risks borne, to be measured, and therefore no way to assess whether those differences deprived the comparison of relevance for lack of appropriate correction. The Conseil d’État found no error of law in that reasoning. For a foreign founder, the lesson is concrete: if your French subsidiary performs different functions from the comparables chosen by the auditor, say so early, quantify the difference in costs and risks, and file the adjustment computation yourself. A bare assertion that the companies are different does not move the court.

B. A Small Subsidiary Is Exposed Too: Information Requests, Privileged Regimes and Neighbouring Risks

Many founders assume that transfer pricing only concerns large groups. The documentation duties described in part II below do have turnover thresholds, but the core weapon, article 57, has none. Whatever the size of your French subsidiary, once the auditor has gathered elements suggesting an indirect transfer of profits within the meaning of article 57, it may demand, during the audit, information and documents specifying the nature of the relations with the foreign related companies, the method used to set the prices of industrial, commercial or financial transactions and the elements justifying it, including any counterparty benefits. The Conseil d’État recalled this power in the ST Dupont decision by quoting the Tax Procedures Code (the LPF, livre des procédures fiscales): the administration may require “La méthode de détermination des prix des opérations de nature industrielle, commerciale ou financière qu’elle effectue avec des entreprises, sociétés ou groupements visés au 1° et les éléments qui la justifient ainsi que, le cas échéant, les contreparties consenties” (Conseil d’État, 5 July 2023, no. 464928, point 7). If the answer is insufficient, the auditor sends a formal notice (mise en demeure) giving thirty days to complete it, and the sanctions described below start running.

The procedural balance then depends on the quality of your file. When the company has supplied, during the audit and where applicable after the formal information request, sufficient elements documenting the method by which the prices of transactions with related companies were determined, the administration keeps the burden of proving the existence of an advantage granted to the foreign related companies, and it must establish, in the exercise of its audit power, that the prices depart from arm’s length, if necessary by restating the elements produced by the company whose accuracy it may challenge. When the file is empty or too thin, the auditor is instead entitled to discard the method claimed by the company and to compute the taxable base from the elements at its disposal, and the company can no longer rely on its own undocumented method before the judge to contest the amount of the advantage assessed. That is what happened to ST Dupont: the court found that the company had not sufficiently documented the resale-price method it invoked, not even through a study produced after the audit, so the administration had lawfully set it aside.

Two neighbouring risks deserve a paragraph because foreign founders meet them in the same audits. If your subsidiary pays royalties, interest or service fees to a company located in a State with a privileged tax regime, the deduction itself can be refused under article 238 A of the French General Tax Code, which targets payments to persons established abroad and subject there to a privileged regime. If your French company holds, directly or indirectly, more than half of a foreign entity in a low-tax jurisdiction, the profits of that entity can be taxed in France even without distribution under the controlled-foreign-company rules of article 209 B of the French General Tax Code. And the financial stakes are straightforward: French companies, including the SAS and SARL (société à responsabilité limitée, the French limited liability company) most founders use, are liable to French corporate income tax (impôt sur les sociétés) under article 206 of the French General Tax Code, at a standard rate now fixed by statute: “Le taux normal de l’impôt est fixé à 25 %.” (article 219 of the French General Tax Code). Every euro of margin added back by the auditor is therefore taxed at 25 percent, before penalties and interest.

II. The Paperwork That Protects You and the Remedies When the Reassessment Arrives

French transfer pricing compliance has three layers, and a founder living abroad must organise all three through the French accountant and the group’s finance team. The first layer is ordinary bookkeeping: every trader, individual or company, must record the movements affecting the assets of the business, since “Toute personne physique ou morale ayant la qualité de commerçant doit procéder à l’enregistrement comptable des mouvements affectant le patrimoine de son entreprise.” (article L123-12 of the French Commercial Code). Without clean intercompany accounts, no transfer pricing defence is possible. The second layer is the full transfer pricing documentation, and the third is an annual disclosure form. Both have thresholds measured at group level, which is why even a small French subsidiary of a large foreign group is caught.

A. Full Documentation, Annual Form 2257 and the Thirty-Day Notice

The full documentation duty (master file describing the group, local file describing the French entity, with functional analysis, method selection and comparable studies) applies to French entities that meet at least one of four alternative conditions, including being held for more than half of capital or voting rights by an entity meeting the size threshold. The official tax bulletin (the BOFiP, bulletin officiel des finances publiques, the binding published doctrine of the FTA) sets the size test at 150 million euros of annual turnover excluding tax or gross balance-sheet assets (BOFiP, transfer pricing documentation duties). The same bulletin recalls that the Finance Act for 2024 lowered this threshold from 400 million euros for financial years opened on or after 1 January 2024. In other words, since financial years opened on or after 1 January 2024, the threshold is 150 million euros of annual turnover excluding tax or gross balance-sheet assets, and a French subsidiary counts as covered when its foreign parent meets that threshold and holds more than half of its capital or voting rights.

The annual disclosure is wider and catches medium-sized groups. Under article 223 quinquies B of the French General Tax Code, French legal entities must file a transfer pricing disclosure when they meet one of four mirror conditions, the first being: “Dont le chiffre d’affaires annuel hors taxe ou l’actif brut figurant au bilan est supérieur ou égal à 50 millions d’euros”. The BOFiP confirms the test in identical terms for the disclosure form (BOFiP, transfer pricing disclosure form 2257). Form 2257-SD is filed electronically, describes the group and aggregates, per nature of transaction above 100,000 euros, the amounts of intra-group transactions and the main pricing method used, and the bulletin sets the filing clock at six months after the corporate tax return deadline.

Missing either layer triggers the same sanction chain. When the audited company does not produce the required documentation, or produces only partial documentation, the auditor issues a formal notice to produce or complete it within thirty days, specifying the documents expected and the applicable penalties. The BOFiP confirms that a company which fails to produce the required documentation within thirty days of the auditor’s formal notice, or within a duly extended period, faces the fine provided for by article 1735 ter of the CGI (BOFiP, transfer pricing penalties). The statute behind the notice provides: “Le défaut de réponse ou la réponse partielle à la mise en demeure mentionnée au III de l’article L. 13 AA et au second alinéa de l’article L. 13 AB du livre des procédures fiscales entraîne l’application, pour chaque exercice vérifié, d’une amende pouvant atteindre, compte tenu de la gravité des manquements, le plus élevé des deux montants suivants : 1° 0,5 % du montant des transactions concernées par les documents ou compléments qui n’ont pas été mis à disposition de l’administration après mise en demeure ; 2° 5 % des rectifications du résultat fondées sur l’ article 57 du présent code et afférentes aux transactions mentionnées au 1° du présent article. Le montant de l’amende ne peut être inférieur à 50 000 €.” (article 1735 ter of the French General Tax Code). For each audited year, the fine is therefore the higher of 0.5 percent of the undocumented transaction amounts and 5 percent of the article 57 adjustments on those transactions, with a 50,000 euro floor, on top of the corporate tax, penalties and late interest on the adjustment itself.

From abroad, five practical measures make the difference. First, sign written intra-group agreements before the transactions start: distribution, services, licence, loan, with price formula, review clause and allocation of risks. Second, keep a functional analysis updated every year: what the French subsidiary does, which assets it uses, which risks it bears. Third, commission or update the benchmarking study supporting the chosen method (comparable uncontrolled price, resale-price, cost-plus, net margin or profit split) and file it where the accountant can produce it within days. Fourth, reconcile form 2257 with the accounts every year so the auditor cannot exploit a gap between the declared amounts and the ledger. Fifth, calendar the thirty-day notice: designate who receives registered mail at the French registered office (siège social), who alerts you, and who sends the file to the auditor, because an expired notice converts a defensible file into a minimum 50,000 euro fine per year.

B. Challenging the Reassessment From Abroad: Procedure, Commission and Treaty Remedies

A transfer pricing reassessment follows the standard contradictory (adversarial) audit procedure, which you can fully operate from abroad through your adviser. After the audit, the administration must send a reasoned adjustment notice (proposition de rectification): “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.” (article L57 of the French Tax Procedures Code). You have thirty days to file written observations, with a possible thirty-day extension on request, and the auditor must reply. Silence or a rejection leads to the formal recovery notice (avis de mise en recouvrement), which opens the claim phase (réclamation contentieuse) before the administration and then, if needed, the appeal before the administrative court (tribunal administratif), with further appeal to the administrative court of appeal (CAA, cour administrative d’appel) and cassation before the Conseil d’État.

Use every rung of that ladder, because transfer pricing cases are often won on method, not on principle. In ST Dupont, the adjustment had already been reduced twice before reaching the judge: once by the auditor in reply to the taxpayer’s observations through a discount on the arm’s length prices, and again following the opinion of the departmental commission on direct taxes and turnover taxes (commission départementale des impôts directs et des taxes sur le chiffre d’affaires), which cut the reintegrated amounts by a further 50 percent (Conseil d’État, 5 July 2023, no. 464928, point 15). Requesting the commission’s opinion is therefore a concrete early lever: it forces a collegial review of the auditor’s comparables and can halve the bill years before a court rules. Before the judge, attack the comparables on functions, assets, risks and geographic markets with quantified corrections, propose your own panel, and defend the method documented in your file, because an undocumented method can simply be discarded, as ST Dupont learned.

Two additional remedies matter specifically for cross-border groups. First, where the same profit is taxed in France by the adjustment and abroad in the hands of the related company, the applicable tax treaty usually provides a mutual agreement procedure (MAP) under which the two States’ competent authorities negotiate the elimination of double taxation, and within the European Union the EU Arbitration Directive of 2017 offers a binding dispute-resolution track when the MAP stalls. File the MAP request within the treaty deadline, which is independent of the domestic claim deadline, and run both tracks in parallel. Second, consider the future: an advance pricing agreement (APA, accord préalable de prix) lets the group submit its transfer pricing policy to the FTA in advance, unilaterally or bilaterally with the other State, so that an agreed method cannot later be challenged as long as the facts match the agreement. The published FTA practice even allows, under conditions, a retroactive application (roll-back) of up to three years. For founders planning new flows, such as shifting the French subsidiary from distributor to service provider or licensing the brand held by the foreign parent, securing the method first is cheaper than litigating it later. Note finally that neighbouring extractions of profit face their own withholding rules: dividends and similar distributions to non-residents fall under the withholding tax of article 119 bis of the CGI, whose rates for corporate beneficiaries are set by article 187 of the French General Tax Code, with treaty reductions and, inside the European Union, the parent-subsidiary exemption available on conditions. Re-labelling a dividend as a service fee does not escape the auditor; it only changes the article under which the adjustment is made.

Conclusion

A French subsidiary that trades with its foreign parent lives under a simple rule: its prices must match what independent companies would agree, and it must be able to prove it within thirty days of the auditor’s formal notice. Article 57 of the CGI creates the presumption through comparison with similar independent companies, the Conseil d’État enforces it strictly on comparables and documentation, as the ST Dupont and 2021 margin-ratio decisions show, and article 1735 ter punishes an empty file with at least 50,000 euros per audited year. The protection is equally simple: written agreements, yearly functional analysis, a benchmarking study supporting the method, a form 2257 reconciled with the accounts, and a designated recipient for the auditor’s mail at the French registered office. If the reassessment still arrives, answer the adjustment notice within thirty days, seek the departmental commission’s opinion, litigate the method with quantified corrections, and open the treaty mutual agreement procedure before its own deadline expires. Organised this way from abroad, a transfer pricing audit becomes a manageable dispute about margins rather than an existential threat to the French subsidiary.
