At a glance. The French tax analysis of an intra-group financing arrangement involves several successive tests. The legal nature and business purpose of the transaction must first be established. Its terms, risk allocation and pricing must then be analysed under the arm’s-length principle. The interest rate also faces specific statutory limitations, notably the reference rate in Article 39(1)(3°) and the related-party financing rules in Article 212. Finally, the remaining net borrowing costs are subject to Article 212 bis, including its thin-capitalisation provisions. Passing one test does not secure the others.
Intra-group financing therefore sits at the intersection of contract law, corporate interest, transfer pricing and interest deductibility. A reliable analysis starts with the actual transaction and its business rationale, continues with the delineation and pricing of the financial risks, and ends with the application of the successive French tax limitations.
1. Identify the amount, purpose and actual nature of the financing
The agreement should identify the amount made available, the currency, the date of availability, the maturity, the repayment schedule, the method used to calculate interest, the security and covenants, and the permitted use of the funds.
The financing must also pursue a lawful purpose and a legitimate business rationale for the borrower. An arm’s-length interest rate does not, by itself, make the corresponding expense deductible. If the loan primarily serves an interest other than that of the borrowing company, its tax treatment may be challenged independently of the level of the rate.
This question may arise, for example, where a subsidiary borrows from its parent company in order to distribute the borrowed funds back to that same parent. Such debt push-down arrangements are not automatically invalid, but they require particularly careful evidence of the borrower’s own corporate interest, financing needs, expected benefits, repayment capacity and realistic alternatives.
The review must also identify the actual nature of the financing. A term loan, revolving facility, shareholder current account, cash-pool debit balance, trade credit, guarantee, equity contribution and hybrid instrument do not create the same rights or expose the parties to the same risks.
Repeated drawings under a short-term facility or a cash-pooling agreement may, depending on the facts, amount economically to stable long-term financing. A persistent debit balance may therefore need to be delineated as a term loan rather than a succession of short-term advances. This change of character affects the assessment of liquidity, duration and credit risks and may consequently justify a different interest rate.
2. Accurately delineate the transaction and allocate the risks
The written contract is the starting point, but it is not conclusive. The parties’ actual conduct and the economically relevant characteristics of the transaction must be consistent with the agreement.
- the commercial purpose and actual use of the funds;
- the amount, currency, maturity and repayment schedule;
- the borrower’s capacity to service and repay the debt;
- the fixed or floating nature of the return;
- the reference rate, margin and reset dates;
- the ranking, security, guarantees and financial covenants;
- extension, cancellation, conversion and prepayment rights;
- the functions performed by each party;
- the risks assumed and controlled by each party;
- the lender’s financial capacity to bear those risks;
- market conditions and the realistic alternatives available at inception.
The allocation of risk is particularly important. The contract should identify which party bears credit risk, liquidity risk, market risk, currency risk and refinancing risk. The return cannot be determined solely by naming one group company as the lender. It must reflect the functions actually performed, the risks effectively controlled and the financial capacity available to bear those risks.
The borrower’s own creditworthiness remains central. The analysis may also need to determine whether an independent lender would have advanced the same amount on the same terms and whether the borrower could reasonably have serviced the proposed debt.
3. Apply the French tax rules in the correct order
The French tax analysis is not limited to asking whether the contractual rate appears commercially reasonable. Several provisions may apply to the same financing, and each addresses a different question.
| Provision | Main question | Practical consequence |
|---|---|---|
| Article 57 CGI | Do the conditions of a cross-border related-party transaction result in an indirect transfer of profits outside France? | The transaction must be accurately delineated and priced consistently with the arm’s-length principle. |
| Article 39(1)(3°) CGI | What reference rate applies to sums made available by a shareholder? | The statutory reference rate constitutes an initial deductibility threshold. |
| Article 212(I) CGI | Can a higher rate applied to related-party financing be deducted? | The borrower must establish the rate it could have obtained from independent financial institutions in analogous circumstances. |
| Article 212 bis CGI | How much of the remaining net borrowing costs may be deducted? | The ATAD-based limitation and, where applicable, the thin-capitalisation rules apply after the rate limitation. |
The reference rate in Article 39(1)(3°) should not be presented as the arm’s-length rate. It is a statutory reference and an initial tax obstacle. Where the contractual rate exceeds it, Article 212 may allow the borrower to justify a higher rate, but the evidential burden rests on the taxpayer.
The rate limitation under Articles 39 and 212 is applied before Article 212 bis. The latter operates on net borrowing costs remaining after the earlier limitations have been taken into account.
A complete review of an intra-group financing must therefore pass through several distinct stages:
- legal validity and business purpose;
- accurate delineation of the financial transaction;
- allocation and control of risks;
- application of the arm’s-length principle;
- Article 39 reference-rate limitation;
- Article 212 market-rate evidence;
- Article 212 bis net borrowing-cost limitation;
- thin-capitalisation analysis, where relevant.
4. Identify the related parties covered by each provision
The expression “related party” is the most accessible general term in a transfer-pricing context. It should nevertheless be distinguished from the specific statutory concepts used by the French Tax Code.
Article 39(1)(3°) historically applies to sums made available by shareholders. Article 39(12) defines a related-party relationship by reference to majority ownership, direct or indirect control, de facto decision-making power or common control by a third enterprise.
The applicable perimeter must consequently be checked lender by lender. A minority shareholder is not necessarily a related party within Article 39(12), while an entity that does not directly hold shares may nevertheless qualify because of indirect or common control.
For financial years ending on or after 31 December 2025, Article 212(I) was extended to cover financing provided by a corporate shareholder as well as financing provided by a related party within Article 39(12). This change reduces the previous asymmetry under which certain minority corporate shareholders were subject to the Article 39 ceiling without necessarily having access to the Article 212 market-rate rebuttal.
The ownership structure, voting rights and actual decision-making powers should therefore be documented rather than inferred from the group chart alone.
5. Apply Articles 39 and 212 to the interest rate
Interest paid on sums made available by a shareholder or covered related party is initially tested against the reference rate in Article 39(1)(3°).
Where the contractual rate exceeds that reference, the excess is not necessarily non-deductible. Article 212(I) permits the corporate borrower to establish the rate it could have obtained from independent financial institutions under analogous conditions.
The Article 39 reference rate therefore acts as a first threshold. Exceeding it effectively moves the taxpayer into an evidential regime in which it must substantiate the higher market rate.
The analysis must focus on the borrowing conditions available to the borrower. It is not sufficient to show:
- the return the lender could have earned elsewhere;
- the rate paid by another group company;
- a general rate observed in the borrower’s industry;
- or the group’s average cost of funding.
The evidence should instead address the borrower’s own characteristics and the actual financing:
- amount and currency;
- pricing date;
- maturity and repayment profile;
- security and ranking;
- fixed or floating return;
- covenants and contractual options;
- standalone credit profile;
- effect of group membership;
- realistic financing alternatives.
The supporting evidence should preferably be prepared when the transaction is concluded. Later evidence is not automatically inadmissible, but it should rely on information that was available or reasonably foreseeable at the pricing date.
6. Assess creditworthiness and the effect of group membership
Creditworthiness should be assessed using both quantitative and qualitative factors.
Quantitative indicators may include:
- leverage;
- interest coverage;
- cash-flow generation;
- liquidity;
- debt-service capacity;
- asset coverage;
- refinancing exposure;
- expected financial performance.
Qualitative considerations may include:
- the borrower’s business model;
- competitive position;
- market and industry conditions;
- country risk;
- management quality;
- purpose of the financing;
- strategic importance within the group.
Group membership may improve a borrower’s credit profile even without an explicit guarantee. The possible effect of implicit support depends on the borrower’s strategic importance, operational integration, the group’s support policy, its history of intervention, the consequences of a default and the group’s own financial capacity.
Implicit support should be evidenced rather than presumed. It also does not, in itself, justify charging a guarantee fee. A fee generally requires an explicit commitment that provides the borrower with an identifiable incremental benefit and exposes the guarantor to an economically significant obligation.
7. Select and document the pricing method
French administrative guidance and the OECD framework recognise several possible approaches, depending on the transaction and the available evidence.
Internal comparable uncontrolled price
An internal comparable may exist where the borrower has obtained similar financing from an independent lender or where the lender has provided comparable financing to an independent borrower. The transactions must nevertheless be sufficiently comparable in terms of amount, currency, maturity, ranking, security, repayment profile and market timing.
External comparable uncontrolled price
Market loans or bonds may be used where the issuer, credit profile and financial instrument are sufficiently comparable. Adjustments may be required for differences in currency, duration, ranking, guarantees, security, contractual options and market conditions.
Cost-of-funds approach
A cost-of-funds method may be appropriate in certain circumstances. It generally starts with the lender’s funding cost and adds operating expenses, a risk premium and an arm’s-length return. Its use must remain consistent with the delineated transaction and with the functions and risks actually controlled by the lender.
Economic models
Expected-loss models, capital-allocation approaches and other financial models may also be relevant. Their assumptions, data sources and calculation steps must be sufficiently transparent to be reproduced and tested.
The base rate and credit spread should normally be examined separately. Other contractual features—including commitment fees, arrangement fees, undrawn facilities, prepayment options and subordination—may require separate pricing.
8. Use the Bercy practical sheets as an evidential framework
The French tax authorities have published eight practical sheets on interest rates for loans from related parties. They are not a substitute for the Tax Code, case law or a transaction-specific analysis. They nevertheless provide a useful indication of the methodology and evidence the authorities are likely to examine during an audit.
The sheets address, among other matters:
- internal and external comparables;
- the borrower’s credit rating;
- the effect of group membership;
- the characteristics of the financial instrument;
- the date at which the rate should be tested;
- the reliability and reproducibility of the data;
- the possible use of evidence prepared after the transaction;
- the need for comparability between the tested loan and the proposed references.
They therefore provide a practical checklist for preparing or reviewing a financial benchmarking study. A robust file should explain not only the final rate or interval but also the successive reasoning that leads to it: delineation, credit assessment, selection of the pricing method, search strategy, comparability criteria, adjustments and conclusion.
9. Article 212 bis and the post-ATAD limitation
The former general limitation commonly known as the financial rabot is no longer the current regime. For financial years beginning on or after 1 January 2019, it was replaced by the ATAD-based limitation in Article 212 bis.
Under the ordinary regime, net borrowing costs are deductible up to the higher of:
- €3 million; or
- 30% of the tax-adjusted EBITDA defined by Article 212 bis.
These thresholds apply to net borrowing costs generally and not only to interest on intra-group loans. The statutory calculation may therefore include other costs and income economically equivalent to interest.
An arm’s-length interest rate may consequently pass the tests in Articles 39 and 212 while remaining partly non-deductible under Article 212 bis. Conversely, unused capacity under Article 212 bis does not demonstrate that the contractual rate is arm’s length.
Carry-forward mechanisms
Net borrowing costs that are not deductible under the ordinary Article 212 bis ceiling may, in principle, be carried forward without time limit and deducted in a later year to the extent that sufficient statutory capacity becomes available.
Unused deduction capacity may be carried forward for five financial years. However, the statute distinguishes this unused annual capacity from the stock of previously disallowed borrowing costs, and the mechanisms are not interchangeable in every situation.
The treatment is more restrictive where the company is thinly capitalised. In particular, the portion disallowed under the second thin-capitalisation ceiling may be carried forward only up to one third of its amount.
The company should therefore maintain a year-by-year schedule distinguishing:
- current net borrowing costs;
- amounts deductible under the ordinary ceiling;
- disallowed costs carried forward without time limit;
- unused annual capacity carried forward for five years;
- amounts subject to the specific thin-capitalisation treatment.
10. Thin capitalisation remains in force
Thin capitalisation was not abolished by the ATAD reform. Since 2019, it has operated within Article 212 bis.
A company is presumed to be thinly capitalised where the average amounts made available during the financial year by related parties within Article 39(12) exceed 1.5 times its equity.
Where this ratio is exceeded, the net borrowing costs are divided between two categories. The ordinary portion is tested against a proportionate fraction of the higher of €3 million or 30% of tax EBITDA. The portion attributable to related-party debt exceeding 1.5 times equity is tested against a proportionate fraction of the higher of €1 million or 10% of tax EBITDA.
A statutory safeguard may disapply this treatment where the company demonstrates, using the required consolidated-account methodology, that its debt-to-equity ratio does not exceed that of its consolidated group.
Specific rules also apply to qualifying central treasury companies and to amounts made available under a centralised cash-management agreement.
11. Analyse cash pooling as a complete arrangement
A cash pool should not be analysed as a collection of isolated daily balances. The agreement and operational evidence should identify:
- whether the arrangement is physical or notional;
- the legal character of debit and credit positions;
- the functions performed by the pool leader;
- the entity controlling liquidity and credit risks;
- the origin and allocation of synergy benefits;
- the participants’ realistic alternatives;
- the method used to set debit and credit rates;
- the remuneration of the treasury entity.
Persistent balances require particular attention. A stable debit position may amount economically to a term loan, while a stable credit balance may resemble a deposit or longer-term financing. Recharacterisation changes the duration and liquidity assumptions and may therefore change the appropriate rate.
The pool leader should not automatically retain the whole internal spread. Its remuneration depends on whether it acts as a routine coordinator, an agent, a service provider or a risk-bearing treasury entity.
Benefits such as access to liquidity, lower external banking costs, reduced idle cash, operational flexibility and improved security should be identified and, where material, quantified.
12. Four decisions that structure the evidential analysis
WB Ambassador — CAA Paris, 29 June 2022, no. 20PA03996
The court confirmed that the taxpayer may establish the market rate by any appropriate means. Bond yields may be considered where issuing bonds constitutes a realistic alternative to the intra-group loan.
The decision also illustrates the need to take account of the borrower’s own risk profile and the specific characteristics of the financing. In that case, the evidence was sufficient to substantiate the 7% rate.
Studialis — CAA Paris, 22 October 2020, no. 18PA01026
Studialis concerned subordinated PIK-type bonds bearing interest at 10%. The taxpayer relied on a financing offer, bank evidence and a benchmarking study based on comparable bond issues.
The court accepted that bond financing could constitute a realistic alternative and concluded that the taxpayer had sufficiently substantiated the higher rate. The decision highlights the value of combining contemporaneous financing evidence with a documented market analysis.
Willink — CAA Paris, 17 May 2024, no. 22PA05494
Willink confirms that an automated credit-rating tool may be used where it compares the borrower with a sufficiently broad population of independent companies operating in a comparable sector.
The decision also shows that identifying a credit rating is only one stage of the analysis. The taxpayer must still document the comparable instruments and the market data used to derive the proposed rate. In Willink, the court ultimately accepted the evidence supporting the rates applied to the relevant convertible bonds.
SAP France — Conseil d’État, 20 September 2022, no. 461639
SAP France concerned the absence of remuneration on credit balances in a cash-pooling arrangement.
The Conseil d’État held that it was insufficient to compare the zero rate solely with the return the company might have obtained by depositing its surplus cash with a bank. The analysis also had to examine whether the company had acted in its own interest when entering into the cash-pooling agreement and what rights and obligations arose from the arrangement.
The decision is important for cash pools because it requires the complete agreement and its economic benefits to be considered rather than isolating the remuneration of a single balance.
13. Build the evidence in the correct sequence
- Identify the legal instrument, parties and enforceable terms.
- Establish the purpose and actual use of the funds.
- Demonstrate the borrower’s own corporate interest.
- Determine whether repeated or persistent balances require a different characterisation.
- Map the relevant shareholder and related-party relationships.
- Analyse the functions performed and risks controlled by each party.
- Assess the borrower’s debt capacity and creditworthiness.
- Examine implicit support and any explicit guarantees.
- Prepare the pricing analysis using contemporaneous data where possible.
- Apply the Article 39 reference-rate test.
- Apply the Article 212 market-rate evidential test.
- Calculate the Article 212 bis net borrowing-cost limitation.
- Apply the thin-capitalisation provisions and carry-forward rules.
- Review cash-pool balances, treasury remuneration and guarantee fees.
- Reconcile the contracts, calculations, invoices and accounting records.
- Update the analysis when a material amendment, renewal or refinancing occurs.
Expert perspective
The interest rate is only one part of the analysis. Many disputes arise because the parties start with a benchmark and attempt to fit the transaction to the result.
The more reliable sequence is the opposite. It begins with the commercial purpose, the company’s own interest and the actual use of the funds. It then identifies the legal and economic nature of the financing, allocates the relevant risks and examines the borrower’s financial capacity. Only after these stages should the rate be determined and tested against the successive French tax limitations.
Cash pooling requires particular discipline. Advantages that appear obvious when the arrangement is created may be difficult to demonstrate several years later. The rights, obligations and expected benefits of each participant should therefore be documented when the arrangement is implemented, rather than reconstructed during an audit.
