1. Corporate Income Tax (Impôt sur les Sociétés — IS)
Corporate Income Tax is the starting point for understanding how France taxes business activity. Any subsidiary incorporated as a separate legal entity — most commonly a SAS (Société par Actions Simplifiée) — pays IS on its French-sourced profits.
Current rates and thresholds
The standard corporate tax rate is 25% across the board. A reduced rate of 15% applies to the first €42,500 of taxable profit for qualifying SMEs, but only when all three conditions are met:
- Annual turnover below €10 million (excluding VAT)
- The share capital is fully paid up
- At least 75% of the capital is held by individuals, or by companies that themselves satisfy these conditions
Reconciling US GAAP and French GAAP
One of the first operational challenges for any American parent company is the accounting transition. French tax law requires financial records to be maintained under French GAAP (Plan Comptable Général), which uses a fundamentally different chart of accounts than US GAAP. Errors here flow directly into your tax calculations and can trigger penalties during an audit.
2. Value Added Tax (VAT / TVA)
VAT is where many US executives hit their first major knowledge gap. Unlike US sales tax — collected once at the final point of sale — French VAT is assessed at every stage of the production and distribution chain. Every business in the chain charges VAT on its sales and recovers the VAT paid on its purchases.
Import VAT and the reverse charge mechanism
France now requires the use of autoliquidation — the reverse charge mechanism — for import VAT. Rather than paying the tax upfront to customs and waiting for a refund, VAT is reported and offset on your monthly VAT return. The cash flow impact is neutral by design.
3. Territorial Economic Contribution (CET)
The CET is a local business tax that funds French regions and municipalities. It comprises two distinct levies.
CFE (Cotisation Foncière des Entreprises)
Calculated on the rental value of any professional premises your company occupies. It is assessed in every municipality where your company holds a registered address or operates an office as of January 1 of the tax year.
CVAE (Cotisation sur la Valeur Ajoutée des Entreprises)
Assessed on the value added generated by your business. The French government has been phasing this tax out in stages, with full elimination currently delayed to 2030.
4. Payroll taxes and social contributions
France's employment cost structure is one of the most significant operational surprises for US executives entering the market. Social contributions add substantially to the cost of every hire.
Additional payroll-based levies
- Apprenticeship tax — finances initial vocational training programs nationally.
- Professional training contribution — funds ongoing employee training and development.
- Employer Housing Contribution (PEEC). Mandatory for companies with 50+ employees — a uniquely French obligation requiring employers to contribute to national social housing.
5. Incentives: the R&D tax credit (CIR)
France's tax environment is demanding — but it pairs that with one of the most competitive R&D incentive programs in the world: the Crédit d'Impôt Recherche (CIR). For any company with a meaningful research or development function, this credit deserves serious attention during your market entry planning. Identifying and documenting eligible expenditures correctly is where many companies leave money on the table.
6. International compliance and tax treaties
As soon as your French subsidiary begins transacting with the US parent, two areas of international tax law require immediate attention.
Dividend withholding tax
When your French subsidiary distributes profits to the US parent, French law imposes a withholding tax on those dividends. The France-USA Double Tax Treaty reduces that rate depending on ownership:
To claim a reduced rate, specific documentation must be filed — including Form 5000 (certificate of tax residency) and Form 5001 (dividend-specific treaty exemption claim).
Transfer pricing
Any transaction between the US parent and the French subsidiary — management fees, IP licensing, intercompany loans, shared service charges — must be priced as if the two entities were unrelated parties. The absence of contemporaneous transfer pricing documentation is itself grounds for a tax reassessment.
Conclusion
Getting your French tax position right is not a formality — it is a foundation. Done well, it turns the French system into a genuine asset: the R&D tax credit can materially change the economics of building a French team, and a properly structured holding arrangement can significantly reduce dividend leakage on repatriation.
