What are the tax specifics of R&D and tax credits (CIR/CII) for a French subsidiary funded by its US parent company?

France offers one of the world’s most generous systems for supporting innovation: the Research Tax Credit (CIR) and the Innovation Tax Credit (CII). For a French subsidiary funded by its American parent company, the main challenge isn’t eligibility, but the justification of expenses and the management of funding flows.

Here are the specific details required to secure these benefits:

1. The core eligibility principle of the CIR/CII

The CIR allows a large part of R&D expenditures (researchers’ salaries, depreciation, operating costs) incurred by the company to be deducted from its Corporate Income Tax (IS). The CII applies to specific innovation expenditures for SMEs.

Localization criteria

Only R&D expenses effectively carried out on French territory are eligible.

No outsourcing abroad

The R&D work must not be outsourced to a related entity abroad (including the US parent company) if it constitutes the core of the project.

2. Managing intercompany funding

The primary challenge arises when the French subsidiary performs the R&D but is entirely financed by its US parent company.

Dual requirement

For expenses to be eligible for the CIR, they must be borne by the company claiming them. If the subsidiary receives a payment from its parent company for this work (in the form of royalties or service fees), this can complicate the claim.

Solution

Funding should ideally take the form of an operating subsidy (subvention d’exploitation) or a capital contribution (capital increase) rather than a payment in exchange for the R&D results. If the subsidiary is characterized as a mere R&D service provider for the parent, the risk of the CIR being challenged increases significantly.

3. Documentation and transfer pricing

The CIR and Transfer Pricing are inseparable in this context.

Risk of dual audit

The French tax authority examines not only the technical CIR file (the R&D aspect) but also the Transfer Pricing documentation (the financial aspect of the exchange of services).

Justification

The documentation must demonstrate that the French subsidiary retains the economic ownership and risk related to the R&D work it performs. If all risk and Intellectual Property (IP) are immediately transferred to the US parent via a poorly structured cost sharing agreement, CIR eligibility is highly threatened.

Conclusion

For a subsidiary funded by the US headquarters, it is crucial to ensure that the flow of money from the parent is structured to maximize the CIR (e.g., via subsidies) and that the Transfer Pricing documentation confirms the economic substance of the work performed in France.
