Transfer Pricing Documentation for SMEs: 2026 Practical Kit (France)

Are you a CFO or owner of a French SME with cross-border related-party flows — management fees, brand royalties, IT cost recharges, intercompany loans, R&D services? You are within the scope of transfer pricing rules, even below explicit reporting thresholds.

Our primer on transfer pricing principles gives you the conceptual framework. This guide is different: it delivers the documentation kit we actually deploy at the SMEs we support. We split duties into three tiers, with precise thresholds, decision trees and an actionable checklist.

Key point: transfer pricing documentation is not a topic reserved for large groups. A French SME with a Spanish, German or US subsidiary can be audited and reassessed if it cannot demonstrate the arm's length nature of its intercompany transactions.

If you tick none of these but regularly invoice management fees or royalties to a related foreign entity, you remain exposed to article 57 CGI: the tax authority can reassess any transaction it deems non arm's length. The initial burden of proof is on them, but the documentary substantiation is on you.

The core rule sits in article 57 of the French Tax Code (CGI): if a French company runs related-party cross-border transactions on terms different from those it would have accepted with an independent third party, the tax authority can reassess its taxable result. No revenue threshold, no exemption — article 57 applies to every cross-border intercompany transaction.

Article 223 quinquies B adds an annual reporting obligation (Form 2257-SD) for groups above thresholds. Article L13 AA of the Tax Procedures Code mandates full documentation (master + local file) during audit for groups above €50M revenue or gross assets. BOFiP BOI-BIC-BASE-80-10-10 details the tax authority's expectations.

Key point for SMEs: you do not have to produce a formal master/local file if you are below €50M AND no other group entity exceeds it. But you remain bound to substantiate your transfer prices on request, and we systematically recommend a proportionate documentation set.

The master file describes the group as a whole. Per BOFiP, it must include:

• A group description (legal and operational organisation chart, geography);
• A business overview (value chain, top-five revenue products/services, principal markets);
• The group's intangibles (IP policy, transfer/licensing agreements, key R&D contracts);
• The intercompany financial transactions (cash pooling, intercompany loans, guarantees);
• The consolidated financial and tax position (financial statements, ongoing APAs, rulings).

Real-world volume: 30 to 80 pages for an SME group. Not a marketing document, not a copy-paste of the annual report — a tax document that will be read line by line by an auditor.

Many SMEs come to us with a master file written once in 2022 and never updated. That is useless. The master file must reflect the audited financial year, so it must be refreshed annually.

The local file documents the French entity's transactions with related foreign entities. It must contain:

• A description of the local entity (internal structure, key competitors, KPIs);
• Detailed analysis of each material intercompany transaction: nature, amounts, counterparty, pricing method, comparables;
• A functional analysis of each flow (who does what, who bears which risks, who owns which assets);
• Annexed intercompany contracts;
• Detailed financial calculations (margin, application of CUP/TNMM/Cost +).

Accepted transfer pricing methods (refresher)#

Caution: TNMM is the most frequent, but it requires a serious comparability study, based on a sound economic database (Amadeus, Orbis). A "Google-based" study will not survive an audit.

Form 2257-SD is the annual transfer pricing return, required if you belong to a group with at least one entity above €400M revenue or gross assets.

Content (summary):

• Main transactions of the French entity with related foreign entities;
• Pricing method by transaction category;
• Material changes during the year (M&A, restructuring);
• Counterparty countries.

Deadline: within 6 months of the corporate tax filing deadline (in practice November Y+1 for a 31/12/Y year-end).

Penalties for non-filing: minimum €10,000 per year, with a possible uplift up to 5 % of the affected transactions (CGI article 1735 ter).

Country-by-Country Reporting (Form 2258-SD) only applies to groups above €750M consolidated revenue. The French parent (or designated entity) reports, by country, revenue, profit before tax, corporate income tax paid, capital, headcount, and nature of activities.

This filing has been public for the EU portion since 2024 (Directive 2021/2101). Out of scope for a typical SME.

Our conviction: transfer pricing documentation is mis-sold to SME owners. It is brought up too late (during an audit) or in too theoretical a way. Yet it is, above all, a management tool: formalising the pricing policy disconnects tax issues from inter-subsidiary friction, lets you cleanly arbitrate between royalty and management fee, and secures margin repatriation to the holding.

We recommend that any SME above €5M revenue with at least one foreign subsidiary should:

1. Map intercompany flows at least annually (who pays what to whom, for what actual service);
2. Document the method chosen per flow category, even without a formal duty;
3. Build a "tax-ready" file you can produce within 48 hours on request;
4. Refresh annually: a 2022 master file does not defend FY 2026.

The cost of proportionate documentation for an SME (5 to 15 intercompany transactions) is far below the cost of an undefended reassessment.

The most underestimated risk is not the direct reassessment on the transaction. It is the economic double taxation that follows. If the French tax authority reattributes €200k of margin to the French entity and the counterparty country (Germany, Spain, US) does not perform a corresponding adjustment, you pay tax twice on the same base.

The mutual agreement procedure (under each bilateral treaty) or EU arbitration (Directive 2017/1852) can resolve this, but the average timeline is 2 to 4 years, during which cash is locked in.

Documenting upfront avoids double taxation. Failing to document means negotiating downstream with no leverage.

• ☐ Applicable level of duty (article 57 only, master/local file, 2257-SD, CbCR);
• ☐ Priority transactions to document (top 5 by amount);
• ☐ Method chosen per flow category (CUP, TNMM, Cost +);
• ☐ Source of comparables (external database vs internal analysis);
• ☐ Update cadence (annual, biannual);
• ☐ Internal owner (CFO, controller, external CPA);
• ☐ Annual budget for production and refresh.

1. Increased scrutiny on "international SMEs": DGFiP now targets smaller groups, especially in digital services and B2B SaaS.
2. Pillar One (profit reallocation) and Pillar Two (15 %): few SMEs in scope, but to anticipate at scale.
3. DAC 7 and platform obligations: marketplaces face additional duties.
4. Strengthened automatic exchange of tax information between administrations (public CbCR, ruling exchange).
5. Digital documentation accepted: filings can be electronic, and the authority accepts links to internal repositories (with access control).
