Yes, you can legally form a French SAS with EUR 1 of share capital. But the total cost of forming and more importantly, running a French company is far more than that single euro.
This guide gives you the complete, unvarnished picture: one-time setup fees, the annonce légale you cannot avoid, RCS registration, ongoing accounting costs, and the single biggest cost that blindsides almost every foreign founder in France employer social charges of 40–45%.
We also compare France’s total cost structure against the UK so you can make a genuinely informed location decision for your European entity.
One-Time Formation Costs
Setting up a SAS (Société par Actions Simplifiée) the most popular structure for foreign investors involves these one-time costs:
| Cost Item | Typical Range (EUR) | Notes |
|---|---|---|
| Share capital deposit | EUR 1 minimum | Legally EUR 1, but see Section 4 below |
| Annonce légale | EUR 150 – 250 | Mandatory legal announcement publication |
| RCS registration (Infogreffe) | EUR 37 – 70 | Registre du Commerce et des Sociétés fee |
| Statuts drafting (lawyer/notary) | EUR 500 – 2,500 | DIY statuts possible but risky for foreign founders |
| Registered office address (1st year) | EUR 300 – 1,500 | Virtual office or domiciliation company in Paris |
| Bank account opening | EUR 0 – 300 | Neobanks (Qonto, Shine) are free or low-cost |
| Formation agent / fiduciary | EUR 800 – 3,000 | Recommended for non-EU founders |
| Realistic One-Time Total | EUR 2,000 – 8,000 | Excluding capital deposit |
Annonce Légale: What It Is and Why It Costs EUR 150–250
The annonce légale (legal announcement) is a mandatory publication required under French company law. When you form a new SAS or any other French company, you must publish a notice in a Journal d’Annonces Légales (JAL) an officially approved legal newspaper in the département where your company has its registered office.
What the Annonce Légale Must Contain
- Company name (dénomination sociale)
- Legal form (SAS, SARL, etc.)
- Amount of share capital
- Registered office address
- Corporate purpose (objet social)
- Name and details of the Président
- RCS registration number (once obtained)
Cost Breakdown
The cost is set by the government at a per-line tariff, updated annually. In Paris (Île-de-France), expect:
- SAS formation: approximately EUR 180–220
- SARL formation: approximately EUR 150–180
- SA formation: EUR 250+ (more complex)
You can publish through online JAL platforms (such as Infogreffe, LégaFrance, or Legalstart) which are cheaper and faster than print newspapers. Online publication is fully legally equivalent to print as of the 2019 reform.
Money-saving tip: Use an online JAL platform. The tariff is regulated but online platforms charge less in ancillary fees. You can expect to save EUR 30–60 versus traditional newspaper publication.
Additional annonces légales are required for subsequent events: modification of statuts, change of Président, share capital changes, dissolution, and liquidation. Budget EUR 150–200 per event.
RCS Registration & Infogreffe Fees
All French commercial companies must register with the Registre du Commerce et des Sociétés (RCS), administered by the greffe du tribunal de commerce (commercial court registry).
As of 2023, registration has been centralised through the Guichet Unique (single window) portal operated by INPI (Institut National de la Propriété Industrielle). The registration fee varies:
- SAS with commercial activity: approximately EUR 37.45 (2026 rate)
- With additional registrations (branch, secondary establishment): additional fees apply
Post-registration, you receive your company’s SIREN number (9-digit national identifier) and SIRET (14-digit site identifier). These are required for every subsequent administrative step VAT registration, social security registration, bank account opening, and supplier contracts.
The EUR 1 Minimum Capital Rule: What It Really Means
The EUR 1 minimum share capital for SAS is real it is not a marketing gimmick. French law genuinely permits it. However, operating a business on EUR 1 of capital has practical consequences that many foreign founders overlook.
Why EUR 1 Is Technically Legal But Practically Insufficient
- French banks will typically require a minimum of EUR 1,000–5,000 in paid-up capital before opening a business account (some neobanks are more flexible)
- French suppliers and landlords often check the bilan (balance sheet) EUR 1 of capital signals undercapitalisation and may affect commercial terms
- Bpifrance guarantee programmes typically require minimum capital levels relative to loan size
- If you need employees from day one, you will need enough cash to cover the first payroll + social charges capital needs to reflect that operational reality
What Capital Level Makes Sense?
| Business Stage | Recommended Capital | Rationale |
|---|---|---|
| Holding/shell entity | EUR 1,000 – 5,000 | Minimal operations, bank account opening |
| Services company, 1–2 staff | EUR 10,000 – 30,000 | Cover 3 months operating costs + social charges |
| Tech startup, seed stage | EUR 30,000 – 100,000 | VC-backable structure, Bpifrance-ready |
| Manufacturing / physical operations | EUR 50,000+ | Asset purchases, lease deposits, supplier terms |
Social Charges: The Hidden Cost That Can Destroy Your Budget
This is the section that matters most. If you read nothing else in this guide, read this.
France’s employer social charges (cotisations sociales patronales) add approximately 40–45% on top of every euro of gross salary. This is not a tax you can plan around or minimise it is a structural feature of French employment law that funds healthcare, unemployment insurance, retirement, and family benefits.
The Real Cost of a French Employee
Critical Budget Rule: When hiring in France, multiply the gross salary by 1.42 to get the total cost to the company. A EUR 60,000 gross salary costs you approximately EUR 85,200 per year.
| Annual Gross Salary | Employer Charges (~42%) | Total Annual Cost |
|---|---|---|
| EUR 25,000 (SMIC level) | EUR 10,500 | EUR 35,500 |
| EUR 40,000 | EUR 16,800 | EUR 56,800 |
| EUR 60,000 | EUR 25,200 | EUR 85,200 |
| EUR 80,000 | EUR 33,600 | EUR 113,600 |
| EUR 100,000 | EUR 42,000 | EUR 142,000 |
Employee-Side Social Charges
In addition to employer charges, employees pay their own social charges of approximately 20–23% of gross salary. This means the employee’s take-home (net) pay is also significantly lower than gross. For a EUR 60,000 gross salary, the employee takes home roughly EUR 46,000–48,000 net. This is important for salary negotiations French candidates will always discuss net salary, not gross.
The CIR Partial Offset
For R&D roles specifically, the gross salary + employer social charges are qualifying expenditure for the Crédit d’Impôt Recherche (CIR). The CIR at 30% means you recover EUR 30 for every EUR 100 of qualifying R&D labour cost including social charges. This significantly improves the economics of hiring researchers in France versus other EU countries.
Reductions Available
- Réduction générale de cotisations (Fillon reduction): Significant employer charge reduction for salaries up to 1.6x SMIC (approximately EUR 27,200 in 2026). Can reduce employer charges to near zero for minimum wage roles.
- JEI (Jeune Entreprise Innovante) status: 50% reduction on employer social charges for R&D employees for qualifying companies (less than 8 years old, R&D spend >15% of costs)
- ZFU / BER zone incentives: Geographic-specific reductions for companies in designated enterprise zones
Annual Accounting & Compliance Costs
French law requires rigorous annual accounts. Even a one-person SAS with minimal activity cannot skip its annual filings. Here is what to budget:
| Service | Annual Cost (EUR) | Notes |
|---|---|---|
| Expert-comptable (accountant) | EUR 2,400 – 8,000 | The biggest ongoing non-salary cost. Required by law. |
| Social declarations (DSN monthly) | EUR 600 – 1,800 | Often included in accountant fee |
| Annual accounts filing (greffe) | EUR 50 – 100 | Filing of comptes annuels at Infogreffe |
| Statutory auditor (commissaire aux comptes) | EUR 3,000 – 8,000 | Mandatory if revenue >EUR 8M OR >50 staff OR balance sheet >EUR 4M (2 of 3) |
| Registered office (ongoing) | EUR 300 – 2,400/yr | Virtual office / domiciliation |
| CIR claim preparation | EUR 1,500 – 5,000 | Specialist R&D tax advisor if claiming CIR |
| Typical Annual Compliance Total (no audit) | EUR 4,000 – 12,000/yr | For a small SAS with 1–5 staff |
Important: France’s expert-comptable system means that accounts must be prepared by a licensed accountant. Unlike in some countries where you can self-prepare accounts, French law de facto requires professional accounting support for any company with employees or meaningful turnover.
France vs UK: Real Cost Comparison (2026)
| Cost Factor | France | UK | Winner |
|---|---|---|---|
| Minimum capital | EUR 1 (SAS) | GBP 1 (Ltd) | Tie |
| Formation cost (DIY) | EUR 400 – 700 | GBP 12–50 | 🇬🇧 UK |
| Employer social charges | 40–45% of gross salary | 13.8% NIC above GBP 9,100/yr | 🇬🇧 UK (significantly) |
| Corporate tax rate | 25% CIT | 25% (main rate, 19% for small) | Tie / slight UK edge for SMEs |
| R&D incentive | CIR: 30% credit | RDEC: ~16% net credit (post-2023) | 🇫🇷 France (significantly) |
| Annual accounting cost | EUR 4,000 – 12,000 | GBP 1,000 – 5,000 | 🇬🇧 UK |
| EU market access | Full EU single market | Post-Brexit: limited | 🇫🇷 France (significantly) |
| DTAA dividend rate (India) | 10% (uniform) | 10–15% (India-UK DTAA) | 🇫🇷 France (slightly better) |
Bottom line: France is more expensive to operate in than the UK, primarily due to social charges. However, if your business involves significant R&D, the CIR makes France potentially cheaper on a net cost basis. And if EU market access is a priority, France wins decisively post-Brexit.
Bpifrance Grants: Offsetting Setup and Operating Costs
Bpifrance (Banque Publique d’Investissement) is France’s national public investment bank for SMEs and startups. It offers several programmes relevant to foreign-owned French companies:
- Aide au développement (ADD): Subsidised loans and partial grants for innovative projects. Typically EUR 30,000 – 300,000.
- Concours i-Lab: EUR 600,000 grant for deep-tech startups (equity-free)
- French Tech Emergence: Support package for La French Tech-labelled startups
- Bpifrance Création: Business plan support and initial funding guidance
Important for Indian-owned companies: Bpifrance grants are available to any company registered in France, regardless of the nationality of shareholders, provided the company’s operations are in France. FEMA-wise, Bpifrance grants received by a French subsidiary are French-origin funds and do not constitute inward remittance to India or affect your ODI position.

Frequently Asked Questions
Can I start a French SAS with exactly EUR 1?
Yes, legally. However, plan to capitalise adequately for 3–6 months of operating expenses. A EUR 1 capital structure will limit your ability to open certain bank accounts and may affect supplier confidence.
Is the annonce légale fee tax-deductible?
Yes. All formation and registration costs, including the annonce légale fee, are deductible business expenses for French CIT purposes.
What is the SMIC in 2026?
The French minimum wage (SMIC) is updated each January 1 and may be adjusted mid-year if inflation exceeds 2%. As of early 2026, the SMIC is approximately EUR 1,760 gross per month (EUR 21,120/year). The total cost to the employer at SMIC level benefits significantly from the Fillon reduction, bringing employer charges close to zero on the minimum wage portion.
Do I need a French bank account to form a SAS?
Yes. You must deposit the share capital in a blocked bank account (compte bloqué) in France before the company is registered. Upon receiving the Kbis, the funds are released. Neobanks like Qonto and Shine facilitate this process for non-resident founders.
What’s the cheapest way to set up a French company?
Using an online legaltech platform (Legalstart, Captain Contrat) and a digital bank reduces formation costs to EUR 500–1,000. However, for non-EU founders without French language fluency, a formation agent is strongly recommended mistakes in the statuts or registration are expensive to correct.
