Why choose a subsidiary in France rather than a branch?
1. Separate legal entity
A French subsidiary is its own legal person, typically incorporated as a SAS (Société par Actions Simplifiée). The US parent's liability is generally limited to its capital contributions — a crucial layer of protection that branches do not provide.
2. Local credibility and access to incentives
A French entity signals long-term commitment and lets you:
- Recruit local talent under French employment contracts.
- Sign commercial agreements with European partners.
- Access the Crédit d'Impôt Recherche (CIR) — France's R&D tax credit, available only to French entities.
3. Strategic and HR agility
The SAS structure allows for custom bylaws that mirror US corporate governance. It is also the only structure (with the SA) qualifying for BSPCE, France's tax-efficient stock-option scheme — vital for competing for top engineering talent.
Step 1: structure and formal authorization
The process begins at the US headquarters. Your board must pass a formal resolution authorizing the creation of the French subsidiary, approving its name, and appointing its first officers.
Pro tip: the SAS is the structure of choice for US scale-ups due to contractual freedom, allowing bylaws to be drafted to mirror US governance practices.
Step 2: legal and financial foundations
Bylaws (statuts)
These define the corporate purpose (objet social), the registered office (siège social), and the rules for appointing officers. The office must be a physical address in France; PO boxes are prohibited, but registered domiciliation services are permitted.
Capital deposit
You must open a "company in formation" bank account in France.
- Legal minimum. €1 (though €1,000–€5,000 is recommended to clear KYC).
- Timeline. Opening a business bank account is often the longest part of the process — 4 to 8 weeks. US-owned entities face additional FATCA-related scrutiny.
Step 3: registration via the "Guichet Unique"
Since 2023, all French business registrations are processed through a centralized digital portal. Your filing must include:
- Signed bylaws and the Certificate of Fund Deposit.
- Affidavit of publication in a French legal journal (JAL).
- Apostilled US documents. Certificate of Incorporation with a sworn translation by a Traducteur Assermenté.
- RBE declaration. Identification of ultimate beneficial owners (UBOs).
Once approved, you receive your K-bis extract — the official ID of your French company.
Step 4: immediate compliance obligations
Tax and VAT
The subsidiary is subject to French Corporate Income Tax (IS) and must obtain an intra-Community VAT number to invoice clients and recover VAT.
Accounting (French GAAP)
French law requires books kept under the Plan Comptable Général (PCG). You must be able to produce the FEC for tax audits — US accounting software typically does not generate this natively.
HR and payroll
French labor law does not recognize "at-will" employment.
- Contracts. Every hire requires a written contract (CDI or CDD).
- Costs. Employer-side social contributions add roughly 45% on top of the base salary.
- Registration. You must register with URSSAF before an employee's first day.
Common pitfalls for US companies
- Using US offer letters. They are legally unenforceable and create significant litigation exposure.
- Hiring exclusive contractors. Can be reclassified as "hidden employment" (travail dissimulé), leading to back-tax liabilities.
- Foreign investment screening. Sensitive sectors (AI, biotech, energy) may require prior approval from the French Ministry of Economy.
- Underestimating timelines. While registration is digital, banking and translations take weeks. Plan for a 2 to 3-month runway.
Conclusion
Setting up a French subsidiary is a manageable process when sequenced correctly. By treating the setup as critical infrastructure rather than a simple checklist, you create a solid foundation for long-term European growth.
