SAS or SARL: complete 2026 guide to choosing

Choosing between an SAS and an SARL is one of the most strategic decisions when setting up a company. These two legal forms dominate the French business landscape, but their distinct legal regimes directly affect the governance, taxation and development prospects of your business. Faced with this crucial "SAS or SARL" choice, understanding the nuances of each status is essential in order to make the right choice for your particular situation.

The fundamental characteristics of each status

The SARL: a structured legal framework

The private limited company (société à responsabilité limitée, SARL) appeals through its simplicity and its well-defined legal framework. This corporate form limits the members' liability to the amount of their contributions, while offering a clear governance structure laid down by the French Commercial Code.

An SARL may have between 2 and 100 members, called "associés" and not "shareholders". The minimum share capital is a symbolic €1, but banks generally require more substantial capital to open a business account. Management is exercised by one or more managers (gérants), who may be members or third parties to the company.

This legal form imposes strict rules on transfers of company shares. Any transfer to an outside third party requires the approval (agrément) of a majority of the members representing at least half of the shares, unless the articles of association provide otherwise.

The SAS: flexibility and contractual freedom

The simplified joint-stock company (société par actions simplifiée, SAS) stands out for its exceptional flexibility in its articles of association. This corporate form allows the members, called "shareholders", to organise the operation of their company freely, subject to compliance with a few mandatory rules.

An SAS may be formed with a single shareholder (SASU - single-shareholder simplified joint-stock company) or with several, with no limit on number. The minimum capital remains set at €1, but economic reality generally calls for a higher amount. Management is exercised by a mandatory chairman (président), who may be supplemented by other management bodies according to the articles. The governance, tax regime and social security status of the manager of the single-shareholder form are set out in our guide to the legal status of the SASU.

Freedom to transfer shares is one of the major advantages of the SAS. Shareholders may freely transfer their shares, unless the articles contain a restrictive clause, which makes it easier for investors to come in or for shareholders to leave.

Governance and decision-making: SARL or SAS?

The democratic operation of the SARL

The SARL imposes a democratic decision-making framework in which each member has a number of votes proportionate to its shares. Ordinary decisions require a majority of the shares present or represented, while extraordinary decisions (amendment of the articles, capital increase) require a qualified majority of three quarters.

An annual general meeting is mandatory to approve the accounts and decide on the allocation of profit. This structure is well suited to family companies or collective projects that need an equitable distribution of power.

The managers are supervised collectively by the members, who may dismiss a manager who is not a member at any time, and a manager who is a member on the conditions laid down for amending the articles.

The freedom of the SAS articles

The SAS offers almost total contractual freedom in organising powers. The articles may provide for tailored majority rules, multiple voting rights, preference shares or even sophisticated shareholders' agreements. The scope and regime of these agreements outside the articles are compared in our article on the shareholders' agreement and the members' agreement.

This flexibility makes it possible to adapt governance to the specific needs of the project: the entry of investors with particular rights, sophisticated exit mechanisms, or a distribution of power that is independent of the distribution of capital.

The chairman of an SAS has extensive powers in day-to-day management, under the control of the shareholders on the terms defined in the articles. This structure is particularly suited to innovative projects, start-ups or companies expected to change rapidly.

Tax regime: a decisive criterion

Taxation of profits in an SARL

The SARL is automatically subject to corporate income tax (impôt sur les sociétés, IS), with a reduced rate of 15% on the first €42,500 of profit for eligible companies, then 25% above that. This separate taxation makes it possible to distinguish clearly between the taxation of the company and that of its members.

The members are taxed personally only on dividends actually distributed, after corporate income tax has been deducted. These dividends are subject to the flat-rate withholding tax (prélèvement forfaitaire unique, PFU) of 30% or, by election, to the progressive scale with a 40% allowance.

A family SARL may opt for the partnership tax regime, allowing profits to be taxed directly in the hands of the members according to their share, thereby avoiding double taxation at company and member level.

Taxation of the SAS

The SAS follows the same tax regime as the SARL as regards corporate income tax. The major difference lies in the impossibility of opting for the partnership tax regime, even in a family set-up.

This constraint can be a tax disadvantage, particularly during the development phase where the company generates profits that the shareholders wish to reinvest without suffering double taxation.

However, the SAS offsets this disadvantage through its ability to issue different categories of shares, allowing tax planning through the creation of preference shares or share subscription warrants (bons de souscription d'actions, BSA).

Social protection of managers

The status of the SARL manager

The social security regime of the SARL manager depends on its shareholding in the share capital. A majority manager (holding more than 50% of the shares) falls within the self-employed (travailleurs non-salariés, TNS) regime and contributes to the URSSAF and the self-employed pension funds.

This status offers lower social security contributions (around 45% of net salary) but lower social protection, in particular as regards unemployment insurance and supplementary pension. The majority manager cannot claim unemployment benefit on ceasing office.

A minority or equal-share manager has the status of assimilated employee (salarié assimilé), with full social protection but higher contributions (around 80% of net salary). This protection includes unemployment insurance under certain conditions.

The chairman of the SAS

The chairman of an SAS systematically has the status of assimilated employee, whatever its shareholding in the capital. This uniformity simplifies social security management and offers optimal social protection: social security, supplementary pension, and the possibility of unemployment insurance subject to conditions.

Social security contributions amount to around 80% of net salary, a higher cost than for a majority SARL manager, but this difference is justified by more complete social cover. The chairman may also enter into an employment contract for technical functions that are distinct from its corporate office.

Transfer and sale of the business

Constraints on transfers in an SARL

The transfer of SARL shares follows a strict formal procedure intended to protect the intuitus personae of the company. Transfers between members, ascendants, descendants or spouses remain free, but any transfer to a third party requires the approval of the members.

This approval procedure can slow down or block the entry of new members, complicating fundraising or a partial sale of the business. Registration duties are 3% of the sale price, which is a not insignificant cost.

The valuation of the shares generally follows traditional accounting methods, which limits the scope for tax planning on a transfer.

The fluidity of SAS shares

The SAS greatly facilitates sale and transfer transactions thanks to the free transferability of shares, unless the articles provide otherwise. This flexibility attracts investors and facilitates external growth transactions.

Registration duties remain the same as for the SARL (3%), but valuation mechanisms can be more sophisticated thanks to preference shares or subscription warrants.

The SAS also allows the issue of free shares to employees and managers, which is a particularly effective motivation and retention tool in growing companies.

Costs of formation and operation

Formation costs

Forming an SARL requires standardised administrative formalities: drafting the articles, publishing a notice of formation and registration with the trade and companies register (registre du commerce et des sociétés). Formation costs range between €200 and €300 for statutory fees, to which are added any fees of a professional. The mandatory structure and the clauses to be tailored in the constitutive deed are discussed in our guide to SARL articles of association.

The SAS follows identical formalities at similar cost. The main difference lies in the potential complexity of SAS articles, which may require the involvement of a company law lawyer, increasing the cost of drafting the articles.

Accounting and administrative obligations

Both corporate forms share identical accounting obligations: keeping regular accounts, preparing annual accounts and filing them with the registry of the commercial court. These obligations generate similar recurring costs, generally between €1,500 and €3,000 a year for a medium-sized company.

The SAS may require more complex general meetings because of the potential diversity of shareholders and their rights, generating additional administrative costs.

Selection criteria according to your situation

Favouring the SARL in certain situations

The SARL is particularly suitable for family projects or medium-sized companies that favour stability and simplicity of management. The status of majority manager is of interest to managers wishing to optimise their social security charges, provided they accept reduced social protection.

Businesses that are not contemplating a fundraising or a rapid opening of their capital find in the SARL a secure and economical legal framework. The possibility of opting for the partnership tax regime is a decisive advantage for some family SARLs.

Opting for the SAS in other cases

The SAS is the natural choice for innovative projects, start-ups or businesses contemplating rapid growth that requires successive fundraisings. Flexibility in the articles makes it possible to adapt governance to the requirements of professional investors.

Managers who favour optimal social protection naturally choose the status of SAS chairman. This corporate form is also suited to international projects or complex legal structures requiring maximum contractual flexibility.

Possible development and conversion

Conversion of an SARL into an SAS

Converting an SARL into an SAS remains possible but requires a unanimous decision of the members and follows a strict formal procedure. This operation generates costs (around €500 to €1,000) and may have tax consequences depending on the circumstances.

This conversion is appropriate when the company wishes to open up to new investors or adapt its governance to rapid growth. The change in the managers' social security regime is often the main motivation for this change.

Other possible developments

Both corporate forms may develop towards more complex statuses: conversion into a public limited company (société anonyme, SA) for large-scale projects, merger by absorption, or demerger according to development needs.

The question "SAS or SARL" is therefore not a final choice, even though any later conversion generates costs and constraints that should be anticipated from the outset.

Choosing between SAS and SARL requires an in-depth analysis of your business project, your development objectives and your personal situation. The SARL favours simplicity and social security optimisation for the majority manager, while the SAS favours flexibility and opening up the capital. This structuring decision deserves professional support in order to assess all the legal, tax and social implications of your choice.
