IP Box in France: Recent court rulings
What does the IP Box involve?
The "IP Box" is a tax mechanism provided for in Article 238 of the General Tax Code (CGI) that allows a reduced tax rate of 10% to be applied to income derived from the exploitation of certain intellectual property rights, particularly in the context of licensing agreements.
In the case of software, the company must demonstrate that the asset is protected by copyright and calculate the eligible income. The option is exercised on a per-fiscal-year basis (whether to opt in or maintain the election) and is formalised by filing a specific schedule.
Judgment of the Administrative Court of Cergy-Pontoise, 5th Chamber, 29 January 2026, No. 2308638
In this case, the taxpayer—a company specialising in the development of telecommunications products and services—filed amended tax returns serving as formal claims to benefit from the special reduced tax rate of 10% provided for under Article 238 (the so-called "IP Box" regime). The tax authorities rejected the request on the grounds that the option had to be exercised in the initial tax return and could not be claimed retroactively via an amendment.
The judges held that Article 238 of the General Tax Code (CGI) specifies no deadline for electing this regime and that no law requires the submission of the supporting schedule at the same time as the initial return. Consequently, the court upheld the right to make such a claim, provided it was filed within the general time limit set out in Article R. 196-1 of the Book of Tax Procedures. Noting that the company had provided sufficiently detailed documentation and that the tax authorities did not dispute the calculation of net income, the court authorised the application of the reduced rate and granted the discharge of the tax liability.
This decision confirms earlier rulings handed down on this matter during 2025.
Key takeaway
Retroactive option: The IP Box regime may generally be elected retroactively by filing an amended tax return or a tax claim, provided that the statutory deadlines under Article R. 196-1 of the French Tax Procedure Code are met.
As a general rule, the amendment must be submitted no later than 31 December of the second year following the year in which the relevant corporate income tax was paid. The decisive date is therefore not only the financial year concerned, but also the year of the tax payment.
For example, if the corporate income tax for the 2023 financial year was paid in 2024, the deadline for filing the amendment would generally be 31 December 2026.
Judgment of the Administrative Court of Poitiers, 1st Chamber, 17 March 2026, No. 2301859
The publisher of the accounting software Macompta.fr simultaneously applied for the IP Box regime and the innovation tax credit (CII) for the 2020 and 2021 financial years. The tax authorities rejected both claims. The courts examined each claim separately and ruled in favour of MACOMPTA regarding the IP Box aspect.
Below are the key takeaways from the ruling by the Administrative Court of Poitiers concerning the IP Box regime.
Key takeaways
Proof of prior existence: Depositing source code with a trusted third party (such as the APP, a judicial officer, or a certification authority) serves as useful evidence to demonstrate prior existence and ownership of rights. While such a deposit is not sufficient on its own to establish the software's originality, it helps substantiate the claim that the asset is an original creation of the company and qualifies for copyright protection;
Revenue allocation: Where subscription revenue comprises both a software licensing component and service elements (hosting, maintenance, support, etc.), an allocation method based on costs incurred during the financial year is acceptable. This methodology involves distinguishing between costs associated with non-eligible services and costs directly linked to the development and operation of the eligible software. The resulting ratio allows revenue to be apportioned between the share eligible for the IP Box regime and the share corresponding to non-eligible services;
Option to elect by asset family: If multiple intangible assets (software modules) generate inseparable revenue (e.g., a global subscription) and the specific contribution of each cannot be reliably determined, the company may elect to apply the IP Box regime at the level of an asset family (e.g., a software suite). Eligible income is then calculated on an aggregate basis for the grouped assets, provided the company can justify their complementarity and the impossibility of meaningful individual tracking.
