  • The Arm’s Length Principle: Article 9, OECD Guidelines and the French Approach

    The arm’s length principle is the central international standard for transfer pricing. It does not ask for an abstract “market price”. It asks what conditions independent enterprises would have agreed in comparable circumstances, and what profits would have arisen under those conditions.

    Applying that principle in France requires three legal layers to remain distinct: Article 57 of the French Tax Code, the associated-enterprises article of the applicable tax treaty and the OECD Transfer Pricing Guidelines.

    At a glance

    • Article 9: the internationally accepted treaty statement of the arm’s length principle.
    • Article 57: the domestic French legal basis for adding back profits indirectly transferred outside France.
    • OECD Guidelines: an influential analytical framework expressly referenced by French administrative guidance, but not prescriptive rules of French domestic law.
    • Comparability: a comparison of conditions, not simply a search for companies with a similar industry code.
    • No necessary tax-avoidance intent: an adjustment may arise even where the parties acted in good faith.
    • Double taxation: a corresponding adjustment in the other state is not automatic and may require a mutual agreement procedure.

    1. What the arm’s length principle means

    Independent enterprises generally negotiate under market forces. Associated enterprises may face commercial, financial and organisational conditions that would not exist between unrelated parties. The arm’s length principle seeks to neutralise the tax effect of those special conditions by reconstructing the conditions that would have been agreed between independent enterprises in comparable circumstances.

    The standard is therefore broader than the invoiced price. It can address:

    • the nature and scope of the transaction;
    • the functions performed and assets used;
    • which party controls and has the capacity to bear economically significant risks;
    • payment terms, guarantees, duration, volume and market circumstances;
    • the commercial strategy and realistically available alternatives; and
    • the amount of profit that the transaction should generate for each party.

    The OECD expressly cautions against assuming that related parties necessarily intended to manipulate profits. Transfer pricing adjustments and findings of fraud or tax avoidance are different legal questions.

    2. Article 9 of the OECD Model Tax Convention

    Article 9 of the OECD Model applies where one enterprise participates directly or indirectly in the management, control or capital of an enterprise of the other state, or where the same persons participate in both enterprises.

    Paragraph 1 then identifies two linked questions:

    1. Were conditions made or imposed in the enterprises’ commercial or financial relations that differ from those independent enterprises would have agreed?
    2. Did those conditions prevent profits from accruing to one enterprise that would otherwise have accrued to it?

    If both questions are answered positively, the affected state may include those profits in the enterprise’s taxable results.

    Paragraph 2 addresses the resulting economic double taxation. The other state makes an appropriate corresponding adjustment where it accepts that the primary adjustment is justified. The competent authorities consult where necessary. This is a coordination mechanism, not an automatic obligation to mirror every foreign reassessment.

    3. The French domestic rule: Article 57

    Article 57 of the French Tax Code is regarded as the domestic equivalent of Article 9, but the two provisions should not be treated as interchangeable.

    • Article 57 supplies the domestic legal basis for the French reassessment.
    • The applicable tax treaty allocates and limits taxing rights between the states.
    • The OECD Guidelines assist with the economic analysis and interpretation of the arm’s length standard.

    A treaty does not ordinarily create a French tax charge that does not exist under domestic law. Conversely, a domestic adjustment must remain compatible with the applicable treaty.

    There is also a useful distinction between the statutory wording of Article 57 and the OECD analytical framework. OECD comparability is central to identifying and pricing the controlled transaction. Under Article 57, however, comparison with similar independent enterprises is expressly a subsidiary method for quantifying the transferred profit where precise evidence is unavailable.

    4. The legal status of the OECD Guidelines in France

    The OECD Transfer Pricing Guidelines 2022 describe the international consensus on applying the arm’s length principle. They cover the delineation of transactions, methods, comparability, intangibles, services, cost contribution arrangements, restructurings, financial transactions, documentation and dispute-resolution tools.

    The October 2025 OECD country profile for France records the French position precisely: the Guidelines are not prescriptive under French domestic law or regulation, but French administrative doctrine expressly refers to them for the arm’s length principle and for transfer pricing methods.

    The Guidelines are therefore highly influential, but they cannot replace the statute, the relevant treaty, French case law or the burden-of-proof rules applicable to a particular reassessment.

    5. Accurate delineation comes before pricing

    The first analytical task is to identify the actual controlled transaction. The written contract is the starting point, not necessarily the end of the enquiry.

    A robust delineation considers five comparability factors:

    1. Contractual terms governing rights, obligations, pricing, duration and termination.
    2. Functions, assets and risks, including who makes the decisions that control economically significant risks and who has the financial capacity to bear them.
    3. Characteristics of the property or services, including quality, volume, maturity and the nature of any intangible.
    4. Economic circumstances, including geography, competition, regulation, market level and timing.
    5. Business strategies, such as market entry, innovation, diversification or temporary penetration pricing.

    Where the parties’ conduct is inconsistent with the contract, the actual conduct may clarify, supplement or in appropriate cases displace the written allocation. A label such as “limited-risk distributor” does not determine the result if the local entity in fact controls material risks or owns valuable contributions.

    6. Comparability is a disciplined enquiry

    Two transactions need not be identical to be comparable. They are sufficiently comparable where no difference materially affects the tested condition, or where reasonably accurate adjustments can eliminate the material effect.

    The analysis should normally:

    • define the tested transaction and the economically relevant characteristics;
    • identify internal comparables before relying exclusively on databases;
    • set transparent geographical, industry, independence and financial criteria;
    • review the qualitative comparability of the retained companies or transactions;
    • make only adjustments that improve reliability and can be supported; and
    • explain the period, data sources, exclusions and final range.

    French law does not formally prefer domestic comparables. The French country profile nevertheless notes that domestic comparables may in practice better reflect local market conditions, while foreign comparables remain acceptable when reliable national evidence is unavailable.

    7. Selecting the most appropriate method

    French administrative guidance follows the OECD distinction between traditional transaction methods and transactional profit methods. There is no statutory hierarchy requiring the same method in every case. The selected method must be the most appropriate in light of the transaction, reliable information and the functions of the parties.

    MethodWhat it testsTypical relevance
    Comparable uncontrolled pricePrice of a comparable uncontrolled transactionCommodities, loans, royalties or goods where reliable price comparables exist
    Resale priceGross resale marginDistribution without unique contributions
    Cost plusGross mark-up on an appropriate cost baseManufacturing or services with comparable functions and cost structures
    Transactional net margin methodNet profit indicator relative to sales, costs or assetsOne-sided cases where reliable net-margin comparables are available
    Transactional profit splitCombined profit allocated by economically valid contribution factorsHighly integrated dealings or transactions involving unique and valuable contributions

    A reliable comparable uncontrolled price is particularly direct, but it is not automatically available. The OECD Guidelines do not require more than one method merely to validate a properly selected and reliably applied method.

    8. Ranges are evidence, not automatic safe harbours

    Imperfect comparability often produces a range rather than a single answer. The French country profile notes the common use of the interquartile range and of the median where the tested result lies outside that range.

    That practice should not become mechanical. The reliability of the initial sample, the degree of comparability, the reason for the tested party’s result and the legal basis for the proposed adjustment remain relevant. Statistical compression cannot cure a poorly delineated transaction or an unreliable search.

    9. Corresponding adjustments and double taxation

    A primary adjustment by France does not itself oblige the other state to grant relief. The other authority may test the principle and amount of the adjustment under the applicable treaty. If agreement is not immediate, the taxpayer may need to request a mutual agreement procedure within the treaty deadline.

    Three points should be checked promptly:

    • whether the treaty contains an Article 9(2)-type corresponding-adjustment provision;
    • the time limit and formal requirements for the mutual agreement request; and
    • whether domestic appeals and the mutual agreement procedure must be coordinated.

    The French administration discusses this interaction in its BOFiP guidance on treaties and transfer pricing.

    10. Why the principle is difficult in practice

    The arm’s length principle is widely accepted because it seeks parity between independent enterprises and members of multinational groups. Its practical limits must nevertheless be recognised.

    • Integrated groups may generate synergies that cannot be observed in stand-alone enterprises.
    • Unique intangibles and specialised services may have no close market comparable.
    • Associated enterprises may enter transactions that independent parties rarely undertake for legitimate commercial reasons.
    • Public databases contain limited contractual and functional information.
    • Tax audits frequently evaluate transactions years after the relevant decisions were made.

    The absence of a direct comparable does not make a transaction non-arm’s length. It requires a more careful examination of the available evidence and, where appropriate, a method such as profit split that better reflects integrated or unique contributions.

    11. A current development: Amount B

    In February 2024, the OECD added the Amount B report as an annex to Chapter IV of the Guidelines. It offers a simplified and streamlined approach for certain baseline wholesale distribution arrangements, using a transactional net margin method and a pricing matrix.

    The approach does not cover every distributor. Transactions involving services, commodities, intangibles, unique and valuable contributions or economically significant risks may fall outside its scope.

    France’s July 2025 administrative guidance does not make Amount B a general domestic pricing rule. France committed, for financial years opened from 1 January 2025, to respect qualifying Amount B outcomes applied by certain covered low-capacity jurisdictions where the stated conditions are met. The BOFiP recorded that no jurisdiction met all cumulative conditions as at 30 June 2025.

    12. A practical analytical sequence

    1. Identify the relevant entities, treaty and domestic legal basis.
    2. Map the commercial and financial relationships and the actual transactions.
    3. Reconcile written agreements with the parties’ conduct.
    4. Analyse functions, assets, risk control and financial capacity.
    5. Identify the economically relevant characteristics and available independent evidence.
    6. Select and apply the most appropriate method.
    7. Reconcile the result with invoices, accounts, tax returns and documentation.
    8. Assess corresponding relief, procedure and deadlines if an adjustment arises.

    13. Expert perspective: a universal principle, not a mechanical formula

    The strength of the arm’s length principle is also the source of its fragility. It is sufficiently flexible to address almost every form of cross-border dealing, but that flexibility can conceal the legal and factual choices on which the result depends.

    A database range should therefore never be allowed to replace the prior questions: What transaction occurred? What advantage is alleged? Who made the decisions? What did the contract require? What did the parties actually do? Which evidence is genuinely comparable?

    The soundest analysis keeps the legal test and the economic technique connected but distinct. Article 57 determines whether and how France may reassess. The treaty governs the international allocation of taxing rights. The OECD framework helps measure the conditions that independent parties would have agreed. None of those layers should silently substitute for another.
