Setting up a Société par Actions Simplifiée (SAS) in France is a strategic choice for entrepreneurs seeking flexibility in managing their business while limiting their liability to their contributions. Whether you are a sole founder or have partners, the SAS provides a legal framework well-suited to innovative projects, startups, or growing businesses. But where do you begin? What are the key steps to register your SAS without complications? This guide walks you through the process, from initial considerations to final formalities, including drafting the articles of association and selecting a registered office. Follow these steps to launch your SAS smoothly and avoid common pitfalls.

Why Choose the SAS Structure for Your Business?

The SAS is increasingly popular among entrepreneurs in France, and for good reason. This legal structure offers several advantages that make it an attractive option for setting up a business.

Limited Liability to Contributions

As with any commercial company, the liability of SAS shareholders is limited to the amount of their contributions. This means your personal assets are protected in the event of financial difficulties. Only the contributions made to the share capital may be at risk.

High Flexibility in Organisation

Unlike other types of companies, the SAS offers almost complete freedom in drafting its articles of association. You can define the rules of operation, decision-making processes, and conditions for shareholders to join or leave. This flexibility allows you to tailor the company’s governance to your specific needs.

Favourable Social Security Regime for the President

The president of an SAS, whether a shareholder or not, is classified as an assimilated employee. They benefit from the general social security system, which provides comprehensive protection (pension, health insurance, unemployment benefits under certain conditions). This feature is often seen as a major advantage compared to other structures like the EURL or SARL.

Enhanced Credibility with Partners

The SAS is perceived as a serious and professional structure, which can facilitate relationships with banks, investors, or clients. Its structured legal framework reassures partners and may ease access to financing or markets.

Key Steps to Set Up an SAS in France

Setting up an SAS involves several steps, some administrative and others more strategic. Below is a detailed process to register your company legally.

Step 1: Validate the Idea and Project

Before starting the formalities, ensure your project is viable and that the SAS is the right structure. Ask yourself the following questions:

  • What is the company’s objet social (business purpose)? (commercial, artisanal, liberal activities, etc.)
  • Who will be the shareholders? (number, distribution of shares, roles of each)
  • What will be the amount of the share capital? (the SAS has no minimum requirement, but a very low capital may harm your credibility)
  • Where will the registered office be located? (personal address, commercial premises, business incubator, etc.)

This reflection phase is essential to avoid costly mistakes when drafting the articles of association or during registration.

Step 2: Draft the Articles of Association of the SAS

The articles of association form the legal foundation of your SAS. They define the company’s operating rules and must be drafted carefully. Here are the essential elements to include:

  • Company name: The name of your SAS, which must be unique and not cause confusion with another business.
  • Business purpose (objet social): A precise description of the activities your company will carry out. Avoid overly vague formulations but allow some flexibility for future changes.
  • Registered office: The official address of your SAS, which will determine the competent tribunal de commerce in case of disputes.
  • Share capital: The total amount of shareholders’ contributions, which can be fixed or variable. Contributions can be in cash or in kind (assets, patents, etc.).
  • Company duration: Typically set at 99 years, but you may choose a shorter period.
  • Shareholders: Their names, addresses, and the amount of their respective contributions.
  • Governance rules: Procedures for appointing and removing the president, shareholders’ powers, functioning of general meetings, etc.
  • Specific clauses: Conditions for transferring shares, pre-emption rights, approval clauses, etc.

To draft your articles of association, you can use online templates, but it is highly recommended to consult a professional (lawyer, chartered accountant) to avoid errors and tailor the document to your situation.

Step 3: Deposit the Share Capital

The share capital of your SAS must be deposited into a blocked account opened in the name of the company in formation. Here’s how to proceed:

  1. Open a business bank account: Choose a bank (traditional or online) and provide a draft of the articles of association, ID for shareholders, and proof of address.
  2. Deposit the funds: Cash contributions must be paid into this account. The bank will issue a certificate of deposit, which is essential for registration.
  3. Release the capital: In an SAS, at least 50% of cash contributions must be released at incorporation. The balance must be paid within 5 years of registration.

If your capital includes contributions in kind (assets, patents, etc.), these must be evaluated by a commissaire aux apports, unless their value is less than €30,000 and they do not represent more than half of the share capital.

Step 4: Publish a Notice of Incorporation in a Legal Gazette

The creation of an SAS must be published in a journal d’annonces légales (JAL) authorised in the department of the registered office. This formality informs third parties of your company’s creation. The notice must include the following information:

  • The company name of the SAS.
  • The legal form (SAS).
  • The amount of the share capital.
  • The address of the registered office.
  • The business purpose (summary).
  • The company’s duration.
  • The names and addresses of the president and shareholders.
  • The competent greffe du tribunal de commerce.

The cost of this publication varies by journal but expect to pay between €150 and €250. Once published, the journal will provide a certificate of publication, required for registration.

Step 5: Register the SAS in the Registre du Commerce et des Sociétés (RCS)

Registration of your SAS is done through the competent Centre de Formalités des Entreprises (CFE), usually the Chambre de Commerce et d’Industrie (CCI) in your department. Here are the documents to provide:

  • A copy of the articles of association dated and signed by all shareholders.
  • The certificate of deposit issued by the bank.
  • The certificate of publication in a legal gazette.
  • A completed M0 form (declaration of company creation).
  • A declaration of beneficial owners (Déclaration des Bénéficiaires Effectifs, DBE), identifying natural persons holding more than 25% of the capital or voting rights.
  • ID for the president and shareholders.
  • Proof of address for the registered office.
  • A cheque to cover registration fees (approximately €40).

Once your file is complete, the CFE will forward it to the greffe du tribunal de commerce, which will register your SAS. You will then receive an extrait Kbis, the official document proving your company’s legal existence.

Step 6: Complete Post-Registration Formalities

After your SAS is registered, a few additional steps are necessary to finalise its creation:

  • Open a permanent bank account: With your extrait Kbis, you can unblock the funds deposited in the temporary account and open a current account in the company’s name.
  • Take out professional liability insurance: Mandatory for certain activities, it is strongly recommended in all cases.
  • Register your company with social security organisations: The president must be affiliated with the general social security system, and any employees must be declared to the URSSAF.
  • Choose a chartered accountant: While not mandatory, an accountant can help manage your SAS’s accounting, tax, and social security declarations.
  • Comply with accounting obligations: The SAS must keep full accounts, prepare annual financial statements, and file them with the greffe du tribunal de commerce.

Costs to Anticipate When Setting Up an SAS

Setting up an SAS incurs several costs, which it is important to anticipate to avoid surprises. Here is an estimate of average costs:

  • Drafting the articles of association: Between €500 and €2,000 if you use a professional (lawyer, chartered accountant).
  • Depositing the share capital: No specific fees, but at least 50% of cash contributions must be released.
  • Publication in a legal gazette: Between €150 and €250.
  • Registration fees: Approximately €40 for RCS registration.
  • Bank fees: Opening a business account (varies by bank).
  • Professional liability insurance: Between €200 and €1,000 per year, depending on the activity.

In total, expect to spend between €1,000 and €3,000 to set up your SAS, depending on the complexity of your project and the service providers chosen.

Mistakes to Avoid When Setting Up an SAS

Setting up an SAS may seem straightforward, but certain mistakes can delay your project or incur additional costs. Here are the pitfalls to avoid:

Neglecting the Drafting of the Articles of Association

The articles of association are the legal core of your SAS. Poor or overly standardised drafting can lead to conflicts between shareholders or governance difficulties. Take the time to tailor them to your project and have them reviewed by a professional.

Underestimating the Share Capital Amount

Although the SAS has no minimum capital requirement, a very low capital may harm your credibility with banks, investors, or clients. Plan a realistic amount aligned with your business needs.

Forgetting Post-Registration Formalities

Registering your SAS is not the end of the process. Do not forget to open a permanent bank account, take out insurance, and comply with accounting and tax obligations. Neglecting these steps can result in penalties.

Choosing an Inappropriate Registered Office

The registered office of your SAS must be a real and stable address. Avoid precarious domiciliations (e.g., at a shareholder’s home) if you plan to move quickly. A fixed address reassures partners and simplifies administrative procedures.

Failing to Anticipate Shareholder Conflicts

Disagreements between shareholders are a leading cause of SAS failures. Include clauses in the articles of association to manage conflicts (pre-emption rights, approval clauses, etc.) and consider a shareholders’ agreement to supplement the articles.

Frequently Asked Questions

What Are the Differences Between an SAS and an SARL?

The SAS and SARL are two popular company structures in France, but they have key differences:

  • Flexibility: The SAS offers great freedom in drafting the articles of association, while the SARL is more regulated by law.
  • Social security regime for the director: The president of an SAS is classified as an assimilated employee, whereas the majority manager of an SARL falls under the self-employed regime (travailleurs non-salariés, TNS), which is less protective.
  • Transfer of shares: Shares in an SAS are easier to transfer than shares in an SARL, which often require approval from other shareholders.
  • Share capital: The SAS has no minimum capital requirement, unlike the SARL (€1 symbolic).

The choice between an SAS and an SARL depends on your project, your need for flexibility, and your personal situation.

Can You Set Up an SAS Alone?

Yes, it is entirely possible to set up an SAS with a single shareholder. This is known as a Société par Actions Simplifiée Unipersonnelle (SASU). The operating rules are identical to those of a standard SAS, but decisions are made by the sole shareholder. The SASU is ideal for entrepreneurs who want the flexibility and social protection of an SAS without partners.

How Long Does It Take to Set Up an SAS?

The time required to set up an SAS depends on several factors, including how quickly the articles of association are drafted and the completeness of your file. On average, expect between 2 and 4 weeks to complete all steps, from drafting the articles to obtaining the extrait Kbis. Using a professional (lawyer, chartered accountant) can speed up the process.

Is an Auditor Required for an SAS?

Appointing an auditor (commissaire aux comptes) is not mandatory for all SASs. It becomes obligatory if the company exceeds two of the following three thresholds for two consecutive financial years:

  • A balance sheet total exceeding €4 million.
  • A turnover (excluding tax) exceeding €8 million.
  • An average workforce of more than 50 employees.

Even if your SAS does not exceed these thresholds, you may choose to appoint an auditor voluntarily, particularly to reassure partners.

What Are the Accounting Obligations of an SAS?

An SAS must comply with several accounting obligations:

  • Keep full accounts: Record all the company’s financial transactions.
  • Prepare annual financial statements: Balance sheet, profit and loss account, and notes.
  • File annual financial statements with the greffe du tribunal de commerce: Within 6 months of the end of the financial year.
  • Retain accounting documents: For 10 years.

These obligations can be complex to manage alone, which is why it is advisable to use a chartered accountant.
