Three key points
- A SARL operates within a more detailed statutory framework; a SAS leaves more to the articles of association.
- The social security regime depends on the chosen structure, the director’s position and their remuneration.
- A future investor, a disagreement or a shareholder’s departure should be considered at the outset.
A société à responsabilité limitée (SARL) is a French limited liability company whose capital is divided into parts sociales. A société par actions simplifiée (SAS) is a French simplified joint-stock company whose capital is divided into actions. Both are forms of ownership interests, referred to here as shares. The articles of association (statuts) set out the company’s organisation. They must reflect the founders’ choices while complying with the applicable French rules. Neither structure should automatically be equated with a company form in another country.
A practical situation
Fictional example. You and another person are starting a service business. You own 60% of the capital and run the company; your co-founder owns 40%. You expect to start taking remuneration soon and may bring in an investor in two years. You need to compare remuneration costs, but also decide who will approve borrowing, how the investor will join and what happens if one founder wants to leave. These questions can point towards different trade-offs.
1. Who will run the company and how will decisions be made?
A SARL is managed by one or more gérants, who must be individuals. French law regulates a significant proportion of shareholder decisions. Within the permitted limits, the articles can define internal powers, provide for particular consultation procedures and strengthen certain protections. This framework makes the rules easier to identify, but you still need to check that it suits your project.
A SAS must have a président who represents the company. Other positions or bodies can be created, such as a directeur général, a committee approving particular transactions or a supervisory body. The articles largely determine how management and decision-making operate. This flexibility requires precise drafting: an unclear procedure may make a decision difficult to adopt or challenge.
You should distinguish everyday management from matters requiring specific approval: significant borrowing, investment, the director’s remuneration or the sale of an essential asset. A higher voting threshold can protect a shareholder, but can also produce deadlock. The appropriate balance depends on the decisions involved and how responsibilities are actually shared.
Owning a majority of the capital therefore does not mean being able to decide everything alone. Equally, minority ownership does not automatically carry a veto. French law, the articles and any shareholders’ agreement (pacte d’associés), which is a separate agreement binding its signatories, must be read together.
2. What will the director’s social security position be?
An individual serving as président of a SAS falls within the general French social security regime when remunerated for that corporate office, as an assimilé salarié. This means being treated similarly to an employee for social security purposes. It does not automatically create an employment contract or unemployment insurance cover for the office.
In a SARL, a majority manager (gérant majoritaire) falls within the self-employed regime. A remunerated minority or equal-share manager generally falls within the general regime as an assimilé salarié. Determining majority status requires care: certain family shareholdings and any joint management arrangement affect the analysis. The percentage held personally is not always sufficient.
For a meaningful comparison, start with the same budget available to the company and assess net income, contributions and the associated entitlements, including retirement, benefits and protection against particular risks. A headline contribution percentage without assumptions is not a sound basis for a decision. Additional insurance can also change the comparison.
The absence of remuneration has different consequences too. An unpaid SAS président does not acquire social security entitlements through that office. A majority SARL manager may still owe minimum contributions. Cover through another activity and your personal needs should therefore form part of the decision, particularly during the start-up phase.
3. How will shareholders join and leave?
In a SARL, transferring shares to an outside party requires agrément: shareholder approval under the statutory rules and the articles. This provides control over the arrival of a new shareholder. However, the procedure, its timetable and the consequences of refusing approval should be considered in advance.
In a SAS, the articles can require approval for share transfers and impose other permitted restrictions. A SAS is therefore not necessarily open to anyone wishing to acquire shares. Transferability depends on the documents adopted. A pre-emption right may, for example, give certain shareholders priority to buy shares offered for sale.
If investors are to receive different rights, a SAS offers suitable mechanisms, including preference shares (actions de préférence), subject to their own conditions. That does not make it compulsory for every company planning to grow. Identify the funding envisaged, the rights investors expect and the cost of putting the required arrangements in place.
Departure deserves as much attention as arrival: how the price will be established, when it will be paid, what happens to shareholder loans and the consequences of a director leaving office. Leaving a management position does not mean selling one’s shares. The two events must be coordinated if that is what the shareholders intend.
4. What should you compare on capital and taxation?
Capital is freely determined in both structures. On incorporation, at least one fifth of cash contributions must be paid into a SARL and at least half into a SAS; the remainder must be paid within five years. This is the payment-up of capital (libération du capital). Low capital reduces the initial contribution, but does not by itself fund the launch.
A SAS and a SARL are generally subject to French corporate income tax, impôt sur les sociétés (IS): the company pays tax on its profits. Under certain conditions, an election may instead allow profits to be taxed at shareholder level. A family SARL has a particular regime for specified activities and family relationships; a project being family-run is not enough to qualify.
You must then distinguish company tax, tax on your remuneration and tax on dividends, which are profits distributed to shareholders. Their social security treatment can differ, particularly for a majority SARL manager. Dividends require distributable amounts and a valid decision; they are not guaranteed monthly income.
| Question | SARL | SAS |
|---|---|---|
| Who manages it? | One or more individual gérants | A président; other bodies are possible |
| How are decisions organised? | More detailed statutory framework, with permitted adaptations | Organisation largely set by the articles, subject to mandatory rules |
| Which social security regime applies to the director? | Self-employed or assimilé salarié, depending on the circumstances | Remunerated président treated as an employee for social security purposes |
| How are share transfers controlled? | Statutory approval for outside parties; check the articles | Restrictions to be arranged in the articles and agreements |
| How are profits taxed? | IS generally; elections subject to conditions | IS generally; election subject to conditions |
5. What steps should you take before choosing?
Begin by describing the project without immediately choosing a structure: activity, participants, contributions, expected work and required income. Identify the decisions each person wants to control. Allocating capital is not a substitute for agreeing how you will work together.
Next, obtain remuneration comparisons using the same economic assumptions. Examine a start-up scenario and a growth scenario. Distinguish capital contributions from amounts lent through a shareholder current account (compte courant d’associé), which create a debt owed by the company and follow different rules.
Finally, test the organisation against three situations: an investor joining, a lasting disagreement and a founder leaving. Check that the articles and shareholders’ agreement are consistent before signing. Incorporation costs matter, but the cost of unsuitable arrangements can emerge years later, during negotiations or a sale.
Can you start on your own?
Yes. The single-shareholder versions are the SASU for a SAS and the EURL for a SARL. An EURL has specific tax and social security features requiring a separate comparison: the table above mainly concerns a project with several shareholders.
Can you change structure later?
A conversion is possible subject to conditions. It requires decisions, checks and sometimes a specific report. Its costs and consequences need to be assessed; it does not remove the need to choose a coherent organisation at the outset.
