SAS or SARL: Which Business Structure Should You Choose in France in 2025?

Choosing the right legal form is one of the first and most important decisions entrepreneurs face when starting a business in France. Among the most popular options are the SARL (Société à Responsabilité Limitée) and the SAS(Société par Actions Simplifiée). Both offer limited liability and are suitable for small and medium-sized businesses, but they differ significantly in how they are managed, taxed, and regulated.

Here’s a detailed comparison to help you make an informed choice in 2025.

1. Governance and Flexibility

SARL: A Rigid, Well-Defined Structure

The SARL is a limited liability company best suited for small businesses or family-run operations. Its structure is clearly outlined in the French Commercial Code, offering less flexibility in management. The law strictly defines the roles and responsibilities of shareholders and managers (gérants), making it more formal and controlled.

SAS: A Modern, Flexible Company Form

The SAS, or simplified joint-stock company, is known for its high degree of flexibility. You can design the company’s internal rules and decision-making process as you see fit, provided they are written into the bylaws. This structure is favored by startups and growing companies, especially those seeking outside investors, due to its adaptable governance.

2. Social Protection for Company Directors

SARL: Stronger Social Coverage

In a SARL, if you’re the majority manager (gérant majoritaire), you’re affiliated with the self-employed workers’ social security scheme (SSI). This offers lower social charges but also limited coverage. Minority managers or non-partner managers are aligned with the general employee regime, offering better protection but higher contributions.

SAS: Directors Are Treated as Employees

SAS presidents and directors are covered by the general social security system, regardless of shareholding. This offers full protection (retirement, health, maternity, etc.) similar to salaried employees. However, it comes at a higher cost, as social contributions are more substantial than in the SARL.

3. Taxation

Corporate Taxation

Both SARL and SAS are taxed by default under the corporate income tax system (Impôt sur les Sociétés – IS). However, under certain conditions, small businesses can opt for personal income tax on profits for a limited period (up to 5 years).

Dividend Taxation

  • In SARL: Dividends paid to majority managers are partly subject to social charges beyond a certain threshold.

  • In SAS: Dividends are not subject to social charges, only taxed under the flat tax or optionally under the progressive income tax scale.

This difference can make the SAS more attractive for distributing profits in some cases.

4. Share Capital and Investment

SARL: Limited to 100 Partners

A SARL can have up to 100 associates, and transferring shares often requires the approval of other shareholders. This makes it more restrictive for external fundraising.

SAS: No Limit on Shareholders

SAS has no upper limit on the number of shareholders, and shares can be more easily transferred or sold. This makes it ideal for startups and companies looking to raise capital or bring in new partners or investors.

5. Accounting and Management Obligations

Both SARL and SAS are subject to standard accounting rules:

  • They must maintain proper books and financial statements.

  • Filing annual accounts with the commercial court registry is mandatory.

There are no significant differences in administrative or accounting workload between the two.

6. When to Choose SARL vs. SAS?

Criteria Choose SARL Choose SAS
Number of founders Small team or family business Any number, including one (SASU)
Governance structure Standard, controlled Custom and flexible
Director’s social protection Self-employed scheme (cheaper) General regime (better coverage)
Fundraising / investors Limited possibilities Easy entry for investors
Dividend strategy Less favorable tax treatment Better dividend tax efficiency

Final Thoughts

If you’re launching a small business or working with family, the SARL provides a clear legal framework with fewer surprises. But if you’re building a startup, planning to raise funds, or need a tailored governance model, the SAS offers the flexibility and modern approach you need.

Still unsure? It’s often wise to consult a legal or accounting advisor to weigh the pros and cons based on your specific project and long-term goals.
