Transfer price: Inadaptation of the method is not sufficient to prove a transfer of profits
A questionable method does not in itself reveal a transferred profit: must we still establish a difference at arm's length price?
Commented decision: Council of State, 8th-3rd Chambers, 7 May 2026, No. 496874
Transfer pricing control is not limited to the choice of the most attractive economically attractive method. Article 57 of the General Tax Code authorizes the administration to reinstate in the results of a French company profits indirectly transferred to related undertakings outside France. But this text has an advantage actually granted, not a methodological imperfection considered in isolation. It is this distinction, essential to the distribution of the burden of proof, which the Council of State specifies in its decision of 7 May 2026, given by the 8th and 3rd chambers assembled and mentioned at the tables of the Lebon Reports.
In the present case, GDF Suez, now Engie, had organised with an American subsidiary and a Luxembourg subsidiary a joint venture to purchase, transport and sell liquefied natural gas. This device, referred to as « single voice », based on three service contracts: logistical tracking of cargoes (« Scheduling »), the management of the LNG fleet (« shipping ») and the intervention of the parent company as a single contact for purchases and sales made on the spot market. The benefits were paid on a cost method plus a 10% margin.
Following controls over the financial years 2011 to 2014, the Administration considered that this remuneration was lower than that which would have been provided by the arm's length principle. According to the auditor, the parent company's business involved an intangible asset of value: a portfolio of standardized framework agreements with many producers or customers. The administration has therefore replaced the « cost plus » a transactional method of sharing profits. In order to determine the distribution on equal shares, it relied on so-called « diversion », applicable to the diversion of a cargo to another geographical area. The corrections resulted in increases in corporate tax, business value added and withholding taxes, as well as changes in the deficits of the integrated tax group.
After two judgements of the administrative court of Montreuil, the Administrative Court of Appeal of Paris, by a judgment of 27 June 2024, largely granted Engie on this chief of reorganization. It found that the diversion clauses did not constitute a relevant comparison term for spot market transactions, that the framework agreements invoked were not single assets of value and that the administration had not compared the remuneration of 10% with that of an independent intermediary. The Minister lodged an appeal in cassation against the articles of the judgment which reduced the taxable bases and pronounced the corresponding discharges.
The question put to the Conseil d'Etat was thus: can the administration establish an indirect transfer of profits by only demonstrating that the transfer price method chosen by the undertaking was not the most appropriate, without determining an arm's length price based on relevant comparisons or parameters?
The Council of State replied in the negative. First, it recalls the two probative channels open to administration: a comparison with independent transactions, which makes the advantage presumed, or, in the absence of such comparison, evidence of an unjustified difference between the agreed price and the market value of the service. He then agreed with the Court's functional analysis that Engie did not perform a strategic function and had a role comparable to that of a broker. It also considers that transactions between related companies cannot provide a relevant comparable and that diverging transactions differed from transactions « spot » by their object, context and parts. Above all, he argues that the possible misadjustment of the taxpayer's method is not sufficient to prove a profit transfer if the administration does not itself determine the level of the arm's length price on the basis of relevant parameters. The appeal is dismissed; only a material error of amount in the appeal judgment is corrected.
The decision thus consolidates a requirement of proof centered on the economic result of the transaction and not on an abstract hierarchy between methods. First, it strictly enshrines the emergence of the presumption of transfer of profits (1), before subjecting the method of substitution of administration to a concrete check of relevance whose practical scope is important (2).
1. A presumption of transfer subject to proof of a real benefit
1.1. The reaffirmation of a demanding probationary scheme based on the arm's length price
Article 57 of the CGI is based on a two-step mechanism. The administration must first establish, in addition to the international non-arm's length relationship, the existence of a practice revealing an advantage granted to the related foreign business. Where it shows that the price charged is lower than that charged to independent customers or that observed between independent similar undertakings, it shall have a presumption of transfer. It is then up to the taxpayer to establish the existence of at least equivalent counterparties. Therefore, the relevant comparison is not merely a tool for assessing relief: it is a condition for shifting the burden of proof.
However, where the administration does not have comparable transactions, the presumption cannot arise automatically. It retains the possibility of demonstrating a liberality, but must then establish an unjustified difference between the agreed price and the market value of the good or service. This second route is more difficult: it requires the reconstruction of an arm's length remuneration with sufficiently objective economic elements. The absence of a perfect comparable therefore does not amount to the impossibility of correcting or to a reduction of the evidence; it requires that the value of the transaction be otherwise stated.
Engie follows on from SA ST Dupont decision of 5 July 2023. The Commission stated that, when the company sufficiently documents its method, the administration bears the burden of establishing that intra-group prices differ from arm's length prices. It also admitted that an insufficient response to an application based on article L. 13 B of the Tax Procedure Book would enable the service to exclude the declared method and use the elements available to it. The Engie case complements this framework: where the administration intends to make use of the presumption of Article 57, the elements it adopts must in fact reveal an independent price or, failing that, enable the value of the service to be established.
As such, the Council of State sets out a net limit: the price of transactions between related companies, or between companies that are themselves dependent, cannot be a relevant comparable. This clarification protects the consistency of the arm's length principle. A controlled transaction can inform the internal functioning of the group or the logic of its allocation keys; However, it cannot prove what would have been agreed upon by independent companies without additional work of justification. Admitting otherwise would make the circular demonstration: the group would itself serve as a standard to establish that one of its prices deviates from that standard.
1.2. The refusal to confuse imperfection of the method with the existence of a transferred profit
The major contribution of the decision lies in point 7. The Council of State distinguishes criticism from method and evidence from result. Even if the method chosen by the company is not the most suitable for the functions performed, this circumstance is not sufficient to demonstrate that the price obtained is lower than the arm's length price. An imperfect method may, in a given case, lead to an acceptable result; Conversely, a recognized method can be misdefined and produce an erroneous price. Article 57 therefore does not establish a policy of transfer pricing: it allows the correction of an objectively established shift of profits.
This dissociation prevents the administration from overturning the burden of proof too early. It is not enough to identify more complex functions than those described by the taxpayer, to prefer a bilateral rather than a unilateral method or to note that contractual remuneration appears to be low. The service must take an additional step: determine an arm's length level or range from « relevant parameters », then highlight the difference with the price charged. Without this objection, the alleged advantage remains hypothetical.
The solution is particularly protective in sectors where transactions are unique and market data scarce. It prohibits the absence of direct comparability from being turned into a presumption against the taxpayer. But it does not grant any immunity to the method of « cost plus », or at the 10% margin retained by Engie. The Council of State does not establish their intrinsic conformity; It only notes that the administration has not established another credible price. A correction could have been made if the service had valued functions, assets and risks on a relevant basis or had produced adjusted independent remuneration.
The scope of the principle also remains linked to the documentary behaviour of the company. The SA ST Dupont case law shows that a lack of documentation may allow the administration to rule out the declared method and to work on the basis of available evidence. The Engie decision does not remove this procedural consequence; It recalls, however, that the administrative evaluation must always be linked to an arm's length price and remain questionable in principle as well as in its amount.
2. A concrete check of the economic relevance of the administrative method
2.1. The adequacy of the profit-sharing method to the functions and transactions involved
The rejection of the appeal results first of all from the functional analysis of the device « single voice ». The court examined Engie's duties, assets mobilized and risks incurred. It concluded that the parent company did not perform a strategic function based primarily on a single valuable asset and that its role did not exceed that of a LNG broker. The Council of State calls this assessment sovereign and only checks the absence of denaturation. The judge of cassation therefore does not substitute his own economic analysis for that of the judges of the merits; it shall monitor the legal regularity of the reasoning and the fidelity to the documents in the file.
The framework agreement portfolio alone could not justify a residual sharing of profits. The Court noted that these documents set out standardised general conditions, models of which were accessible to market operators. Their possession was not confused with a private clientele or a rare intangible asset. This finding undermined the presupposition of administration: if Engie did not make a single and decisive contribution to value creation, a half-distribution of the overall benefit might over-remunerate an intermediation function.
The solution joins the logic of OECD principles on the transactional method of profit-sharing as a methodological insight. This method is best suited when several parties make unique and valuable contributions, when operations are highly integrated or when economic significant risks are assumed jointly. Conversely, it is in principle less appropriate when a party performs simple functions without any particular contribution. These principles are not, in the decision commented on, the value of an autonomous rule; They nevertheless show why functional analysis is decisive in choosing a method.
Above all, the diversion clauses could not support the 50% sharing rate. On the one hand, some came from intra-group agreements and therefore did not reveal the behaviour of independent parties. On the other hand, the transactions compared differed substantially. A diversion modifies the performance of an initial supply contract and implies the agreement of the parties to that contract; a cash market transaction involves the purchase or sale of volumes and involves a separate intermediary. The Council of State thus approves the court of having retained differences of object, context and parties large enough to deprive the comparison of relevance.
The administration had finally proposed no convincing alternative measures. It had not determined the share of profit corresponding directly to the transactions « spot »does not compare the 10% margin to a commission paid to an independent broker, nor does it justify the split key by the relative value of each entity's contributions. By replacing a 50% key from a different operation, she had claimed a distribution more than she had demonstrated. The failure of the correction is therefore due both to an incorrect delineation of the transaction and to the absence of any probative parameterization of the chosen method.
2.2. A strong practical scope, without sanctification of the taxpayer's policy
For the administration, the decision imposes a discipline in three stages. It must first define precisely the controlled transaction in terms of functions, assets and risks. It must then choose a method consistent with this delimitation, without automatically absorbing a centralized organization into a strategic contribution. Finally, it must quantify the arm's length price: adjusted independent comparables, remuneration of an independent provider, economically justified allocation keys or other robust valuation. Profit sharing is not prohibited, but its application cannot be based on a key imported from a different or controlled transaction.
For groups, the judgment points out symmetrically the importance of contemporary and coherent documentation. The description of functions must not be purely contractual: it must be corroborated by the means actually mobilised, the decisions actually taken and the risks incurred. The taxpayer has an interest in explaining why a function remains routine, why a single asset is actually standardized, and how the margin is tied to market data. The Engie case was won not because the 10% margin would be assumed to be fair, but because the factual analysis allowed to challenge the economic foundations of the administrative method.
The decision is also of litigation interest. The Council of State carefully separates control levels. The identification of functions, assets and risks is the sovereign discretion of the trial judges, subject to denature. The relevance of comparables is validated in the light of the concrete differences noted by the court. On the other hand, the conclusion that simply an inappropriate method is not sufficient to prove a transfer is a fully controlled rule of law in cassation. This architecture gives the trial judges a central role in examining complex economic cases while ensuring a uniform standard of probation.
However, there is still a difficulty. Profit-sharing methods are used precisely when direct comparables are scarce; require « relevant parameters » without defining their degree of precision leaves a margin of uncertainty. However, the interpretation of the judgment should be avoided. The Council of State does not necessarily require a perfect comparison. It requires that the chosen price or allocation be linked to elements that reflect the economic contributions of the parties. A key based on relevant costs, assets actually committed, control of sufficiently adjusted risk or independent transactions could satisfy this requirement if its choice and implementation are demonstrated.
Ultimately, the decision of 7 May 2026 strengthens legal certainty without weakening the principle of arm's length. It recalls that the administration may correct an intra-group price, but cannot deduct the existence of an advantage from its sole preference for another method. Between the method and the adjustment must take place a demonstration: that of an independent price or an arm's length value built from relevant parameters. It is this requirement that turns an economic intuition into tax evidence.
