France SAS vs SARL: Complete 2026 Comparison Guide

Choosing between an SAS (Société par Actions Simplifiée) and a SARL (Société À Responsabilité Limitée) is the single most consequential decision French founders make at incorporation. Both are limited-liability commercial companies registered through the Guichet Unique at INPI since 1 January 2023 (Décret n°2021-300). Both can be formed with €1 minimum capital under, respectively, Code de commerce art. L.227-1 and L.223-2. Yet the two regimes diverge sharply on statutory freedom, director social-security treatment, share-transfer rules, and investor appetite. This 2026 guide walks through every axis, citing the article numbers you would otherwise have to chase across 19 books of the Code de commerce.

1. The Statutory Architecture

The SAS framework sits at Code de commerce art. L.227-1 to L.227-20-1. It is a deliberately skeletal regime: art. L.227-9 hands governance design to the bylaws (“statuts”), specifying only a small list of decisions that must be reserved to collective approval (account approval, capital change, merger, dissolution).

The SARL framework sits at Code de commerce art. L.223-1 to L.223-43. Almost the opposite design philosophy: every major question — share transfers (L.223-14), gérant powers (L.223-18), majorities for collective decisions (L.223-29 and L.223-30) — is fixed by the Code itself. Bylaws fill in the blanks but cannot rewrite the structure.

Practical corollary: the SAS bylaws document is typically 30–60 pages because everything must be drafted explicitly. The SARL bylaws document is often 8–15 pages because the Code does most of the work. Source: https://www.legifrance.gouv.fr/codes/article_lc/LEGIARTI000038799575/

2. Capital and Contributions

Both forms accept €1 nominal capital. Both accept apports en numéraire (cash), apports en nature (in-kind), and apports en industrie (contribution in industry — skills/services, non-counted toward floor capital).

Two divergences that catch founders out:

• Cash paid-in at incorporation: SAS requires at least half of cash contributions paid in at signing (L.227-1 al. 4 referencing L.225-3); SARL requires at least one fifth (L.223-7). Both allow the balance within 5 years.
• In-kind valuation: Both forms require a commissaire aux apports if any single in-kind contribution exceeds €30,000 (Décret n°2010-1638) or total in-kind exceeds half the capital. Below both thresholds, unanimous waiver is permitted.

3. Directors and Their Social-Security Regime

The SAS is represented by a Président (L.227-6), a SARL by one or more Gérants (L.223-18). The two roles look superficially similar but trigger entirely different social-security regimes:

The arithmetic: a freelance founder paying themselves €40,000 net through a SASU pays roughly €30,000 in social charges; the same founder using a single-member SARL (EURL) as gérant majoritaire pays roughly €17,000. The €13,000 annual gap is the single biggest reason solo founders without external investors choose EURL/SARL over SASU/SAS. Source: https://www.urssaf.fr

The trade-off: TNS coverage is thinner. There is no chômage entitlement for either regime in respect of mandate-only remuneration; the régime général gives slightly better illness/maternity cover than the SSI.

4. Share Transfers — Free vs Approved

This is the second great divide.

SAS shares (actions) are freely transferable to third parties under Code de commerce art. L.228-23 (applied to SAS via L.227-1) — unless the bylaws contain restrictions. Bylaws may install pre-emption clauses, agrément (approval) clauses, exclusion clauses (L.227-16), and inalienability clauses up to 10 years (L.227-13).

SARL shares (parts sociales) face a statutory approval requirement for transfers to third parties under L.223-14: the transfer must be approved by partners representing at least half the capital (or higher if bylaws provide). Transfers between partners, ascendants, descendants, or spouses are free unless bylaws say otherwise (L.223-13, L.223-16).

For a startup planning to add investors and key employees, the SAS regime is decisively cleaner — investor counsel will not even open negotiations on a SARL.

5. Cumul des Mandats and Multiple Roles

SAS: No statutory cumul ban — a Président may simultaneously be Président of other SAS or gérant of SARL. SA-style restrictions in art. L.225-21 do not apply to SAS (Cass. com. 13 mars 2007).

SARL: No statutory cumul ban either, but each remunerated mandate triggers separate URSSAF/SSI cotisations.

6. Accounting and Audit Thresholds

Both forms are subject to identical statutory-auditor (CAC) thresholds since Loi PACTE (Loi n°2019-486) and Décret n°2019-514: a CAC is required if the company exceeds 2 of 3 thresholds (balance €5M / turnover €10M / 50 employees) at FY-end.

Both must file annual accounts at the greffe within 1 month of approval (2 months online) under Code de commerce art. L.232-21. Both may opt for confidentiality if they qualify as small (Code de commerce art. L.232-25).

7. Decision-Making Mechanics

SAS — collective decisions are handled exactly as the bylaws specify (L.227-9), provided the floor list (account approval, capital change, merger, dissolution, change of legal form, appointment of auditor) is reserved to the associés. Voting can be unanimous, majority, supermajority, electronic, or in writing — the bylaws decide.

SARL — collective decisions follow Code-fixed majorities: ordinary decisions (account approval, gérant remuneration) require partners representing more than half of parts sociales (L.223-29); statutory modifications require partners representing at least two-thirds of parts sociales (L.223-30, post Loi du 4 août 2008).

For founders contemplating future capital raises with anti-dilution clauses, supermajority blocks, drag-along/tag-along, and reserved-matters protection: SAS is the only credible vehicle.

8. Conjoint Collaborateur and Family Structures

If the spouse of a SARL gérant majoritaire works regularly and unpaid in the business, declaration of “conjoint collaborateur” status is mandatory under Code de la sécurité sociale art. L.121-4 (post-Loi PACTE 2019). The status grants social-security rights (retraite, maternité) at concessional cost.

The same status is theoretically available to SAS Président spouses, but is rare in practice.

9. Tax — Identical by Default, Optional Divergence

Both SAS and SARL fall under corporate income tax (impôt sur les sociétés — IS) by default under Code général des impôts art. 206. Standard rate 25% (since 2022); reduced rate 15% on the first €42,500 of profit for SMEs meeting CGI art. 219 I-b.

Both can opt for transparent taxation (impôt sur le revenu — IR) for up to 5 fiscal years if they meet conditions of CGI art. 239 bis AB (SAS) or art. 239 bis AA (family SARL).

VAT (TVA) and CFE rules are identical for both forms. There is no tax reason on its own to prefer one form.

10. Bylaws Drafting — Cost and Complexity

Because the SAS gives almost everything to the bylaws (L.227-9), the drafting must cover:

• Voting majorities for every category of decision;
• Pre-emption and agrément clauses;
• Anti-dilution and reserved-matters protection;
• Inaliénabilité (lock-up) periods;
• Exclusion/withdrawal mechanisms;
• Director appointment and revocation rules;
• Conventions règlementées disclosure (L.227-10).

A SARL can rely on the Code defaults for almost all of these. For a founder who genuinely intends to stay small and family-run, the SARL is faster, cheaper to draft, and harder to mis-design.

11. The 2026 Decision Tree

Use this if you are signing statuts in the next 30 days:

1. Will you raise external capital in the next 24 months? → SAS.
2. Are you the sole founder, want low social charges, no external investors, and remuneration ≥ €30,000? → SASU vs EURL — see our companion article on solo structures. EURL often wins on charges.
3. Two-to-five family co-founders running a small commercial business? → SARL — cheaper to operate, simpler bylaws, gérant majoritaire can be TNS.
4. You are a freelance professional consulting / dev / design with a single client base? → Compare SASU vs micro-entrepreneur and EURL — the right answer depends on revenue level (above ≈ €60,000 SASU/SAS becomes inefficient).
5. You are non-EU resident? → SAS / SASU only — SARL gérance abroad triggers carte de séjour passeport-talent issues; SAS Président can be remote until residence is required.

12. After the Decision — The First-Year Calendar

Whichever form you choose, the first-year compliance calendar is identical:

• Day 0–10: Sign statuts → bank deposit → JAL publication → Guichet Unique submission.
• Within 30 days of Kbis: Déclaration des Bénéficiaires Effectifs (DBE) — Code monétaire et financier art. L.561-46 (penalty: 6 months / €7,500 under L.574-5).
• Within 3 months of Kbis: Optional IR election if eligible (CGI art. 239 bis AB / AA).
• Before first hire: DPAE 8 days before start (Code du travail art. R.1221-1).
• Yearly: Approval of accounts within 6 months of FY-end; filing at greffe within 1 month.
