French Business Legal Forms
The Legal Framework
French business legal forms are governed by the Code de commerce, the Code civil, and the Code général des impôts. The law distinguishes between entreprises individuelles (sole proprietorships) and sociétés (companies). The choice of legal form determines the entrepreneur’s liability, tax treatment, governance structure, and regulatory obligations.
The number of legal forms available to French entrepreneurs is extensive. The most commonly used forms are the EI (sole proprietorship), EURL (single-member limited liability company), SARL (limited liability company), SAS (simplified joint-stock company), SA (public limited company), SNC (general partnership), and SCA (limited partnership with shares). Each form reflects different trade-offs between liability protection, flexibility, and regulatory burden.
Entreprise Individuelle (EI)
The entreprise individuelle is the simplest form of business in France. The entrepreneur operates the business as a natural person without creating a separate legal entity. The entrepreneur is personally liable for all business debts without limitation, and the business assets are not legally distinct from personal assets.
The Loi n° 2022-172 of 14 February 2022 (the Loi en faveur de l’activité professionnelle indépendante) introduced the patrimoine professionnel (professional patrimony) regime, which permits the independent entrepreneur to separate personal and professional assets by registering a declaration of professional assets with the greffe du tribunal de commerce.
Despite the liability risk, the EI remains popular for micro-entrepreneurs and for businesses with low operating risk. The EI benefits from simplified accounting obligations (the micro-BIC and micro-BNC regimes) and the régime fiscal de la déclaration contrôlée for income tax purposes.
EURL (Entreprise Unipersonnelle à Responsabilité Limitée)
The EURL is the single-member variant of the SARL, governed by Articles L. 223-1 to L. 223-43 of the Code de commerce. The EURL has a single shareholder, who may be a natural or legal person. The shareholder’s liability is limited to the amount of their capital contribution.
The EURL provides limited liability while offering simplified governance (no requirement for a board of managers). The sole shareholder exercises the powers of both the general meeting and the manager. The EURL may elect to be taxed as a corporation (impôt sur les sociétés) or as a transparent entity (impôt sur le revenu).
The EURL is appropriate for solo entrepreneurs who require limited liability but do not need the flexibility of the SAS. In Cass. com., 12 janvier 2021, the Cour de cassation confirmed that the sole shareholder of an EURL may be held personally liable for the company’s debts only in cases of fraud, gross mismanagement, or commingling of assets.
SARL (Société à Responsabilité Limitée)
The SARL is the most common form of French company for small and medium enterprises. Governed by Articles L. 223-1 to L. 223-43 of the Code de commerce, the SARL requires a minimum capital of €1 (though a higher capital is typical for commercial credibility). The maximum of 100 shareholders.
The SARL is managed by one or more gérants (managers), who may be shareholders or third parties. The gérant is appointed by the shareholders and may be removed only by a vote representing more than half of the capital, unless the articles of association provide otherwise. The gérant’s powers are defined by law and the articles of association.
The SARL must hold an annual general meeting to approve the accounts and appoint the gérant. Decision-making is based on majority voting, with certain fundamental decisions (e.g., amendment of articles, increase of capital, merger) requiring a qualified majority of three-quarters of the shares.
The SARL is subject to the régime fiscal de l’impôt sur les sociétés, unless the company elects the transparency option available for small SARLs. The Cour de cassation in Cass. com., 5 février 2020 held that the gérant of a SARL owes a duty of loyalty to the company and may be held liable for breach of this duty in the same manner as a director of an SA.
SAS (Société par Actions Simplifiée)
The SAS is the most popular legal form for French companies requiring maximum flexibility. Introduced by Law No. 1994-1 of 3 January 1994 and substantially reformed by the Loi Pacte of 2019, the SAS has become the dominant choice for French growth companies, start-ups, and joint ventures.
The defining feature of the SAS is contractual freedom. The shareholders may organise the governance of the company as they see fit, subject to the mandatory provisions of Articles L. 227-1 to L. 227-20 of the Code de commerce. The SAS must have a président (president), who represents the company vis-à-vis third parties, but may designate other corporate officers (directeurs généraux) and create additional governance bodies (comités consultatifs, conseils de surveillance).
The SAS has no minimum capital requirement (€1 is legally sufficient, though practice suggests a minimum of €1,000 for commercial credibility). The SAS may have a single shareholder (SASU — Société par Actions Simplifiée Unipersonnelle), offering the flexibility of the SAS with the simplicity of single ownership.
The SAS is subject to impôt sur les sociétés and is required to appoint a commissaire aux comptes (statutory auditor) where specified thresholds (balance sheet €4 million, turnover €6 million, employees 50) are exceeded. The Cour de cassation in Cass. com., 18 mars 2021 confirmed that the président of an SAS may be held liable for corporate torts on the same basis as the gérant of an SARL.
SA (Société Anonyme)
The SA is the traditional form for large French companies with a public or institutional shareholder base. Governed by Articles L. 225-1 to L. 225-253 of the Code de commerce, the SA requires a minimum capital of €37,000 (for public offerings) or €225,000 (for non-public companies).
The SA may adopt either the structure moniste (single board) or the structure dualiste (dual board). The moniste structure comprises a conseil d’administration (board of directors) led by a président-directeur général. The dualiste structure separates the directoire (management board) from the conseil de surveillance (supervisory board).
The SA is subject to strict governance and disclosure requirements, including the appointment of a commissaire aux comptes regardless of size, the preparation of detailed annual reports, and the publication of regulated information. The SA must hold annual and extraordinary general meetings according to the procedures of Articles L. 225-96 to L. 225-104.
The SA is the preferred form for companies seeking a stock exchange listing. In Cass. com., 11 septembre 2020, the Cour de cassation confirmed that the directors of an SA owe a duty of care to the company and may be held liable for imprudent management (faute de gestion) resulting in corporate loss.
SNC (Société en Nom Collectif)
The SNC is a general partnership in which all partners are jointly and severally liable for the partnership’s debts without limitation. Governed by Articles L. 221-1 to L. 221-17 of the Code de commerce, the SNC is used primarily for family businesses and professional collaborations where personal liability is accepted.
All partners have the status of commerçant (merchant) and must be registered in the Registre du Commerce et des Sociétés. The SNC is managed by one or more gérants appointed by the partners. Fundamental decisions require unanimous consent unless the articles of association provide for majority voting.
The SNC is tax transparent: profits and losses are attributed directly to the partners for income tax purposes, avoiding the double taxation applicable to corporations.
SCA (Société en Commandite par Actions)
The SCA is a limited partnership with shares, combining the features of a partnership and a joint-stock company. Governed by Articles L. 226-1 to L. 226-14 of the Code de commerce, the SCA distinguishes between commandités (general partners with unlimited liability) and commanditaires (limited partners whose liability is limited to their capital contribution).
The SCA is managed by the general partners, while the limited partners are passive investors. The SCA is listed on Euronext Paris and is used by certain French holding companies and family-controlled groups.
Choice Criteria
The choice of legal form depends on several factors. Liability is the primary consideration: entrepreneurs seeking limited liability will choose EURL, SARL, SAS, SA, or SCA, while those prepared to accept personal liability may choose EI or SNC.
Taxation is a critical factor. Transparent entities (EI, EURL with IR election, SNC) avoid the corporate tax rate (25% in 2026) and are taxed at the shareholder’s marginal income tax rate. Corporate entities (SARL, SAS, SA) are subject to the impôt sur les sociétés at 15% for the first €42,500 of profit and 25% for profit above this threshold.
Governance flexibility is another important consideration. The SAS offers the greatest flexibility for venture capital investment, including the ability to issue different classes of shares, create veto rights, and structure bespoke governance arrangements.
Registration (RCS)
All commercial companies must be registered in the Registre du Commerce et des Sociétés maintained by the greffe du tribunal de commerce. Registration is a constitutive requirement: the company acquires legal personality only upon registration.
The registration application must include the company’s statutes, the identity of the managers, the registered office address, and a declaration of beneficial ownership. The registration fee varies by legal form and registered capital.
The guichet unique (single window), introduced by the Loi Pacte of 2019, centralises the registration process and permits online filing through the formalites.entreprises.gouv.fr portal.
Conclusion
French business law offers a diverse range of legal forms, from the simple EI to the complex SA and SCA. The SAS has become the dominant form for its flexibility and suitability for growth and investment. The SARL remains the standard choice for small and medium enterprises, while the SA is preferred for large companies and listed entities. The choice of form requires careful consideration of liability, governance, and tax implications.
