SA Company in Switzerland: Société Anonyme Guide

An SA (Société Anonyme) in Switzerland is the French-language name for a joint-stock company — the exact same legal entity that German-speaking cantons call an AG (Aktiengesellschaft). Both are governed by Articles 620–763 of the Swiss Code of Obligations. The difference is purely linguistic. If you register a company in Geneva, Lausanne, or Neuchâtel, the Commercial Register will record it as an SA. Register the identical structure in Zurich or Bern, and it becomes an AG. Same capital requirements, same governance rules, same legal protections.

SA vs AG: Same Entity, Different Language

Switzerland has four national languages, and company names change accordingly. Federal law defines one entity type; each linguistic region uses its own term.

Swiss Company Names by Language

The legal framework is federal. Art. 620 CO defines the SA/AG as a company with a fixed capital divided into shares, where shareholders are not personally liable beyond their capital contribution. Whether the articles of association are drafted in French or German, the obligations are identical.

A practical consequence: if a Zurich-based lawyer sees “SA” on a contract, they know immediately it is a standard Swiss joint-stock company registered in a French-speaking canton. No further investigation is needed. The entity carries full legal weight across all 26 cantons.

Key Features of the SA (Identical to the AG)

• Minimum share capital: CHF 100’000 (at least CHF 50’000 paid in at formation)
• Shareholder privacy: names do not appear in the public Commercial Register
• Board requirement: minimum one member, at least one person with signatory authority must be Swiss-resident
• Audit obligation: required if the company exceeds two of three thresholds (CHF 20m total assets, CHF 40m revenue, 250 full-time employees)
• Freely transferable shares: bearer shares were abolished in 2020, but registered shares transfer without notarial involvement

Forming an SA in Romandie

The formation process for an SA follows the same federal procedure as an AG formation. The difference lies in language: documents are in French, the notary conducts proceedings in French, and the Commercial Register (Registre du Commerce) operates in French.

Formation Steps

1. Draft the statuts (articles of association) — equivalent to the German Statuten. Must include the company name with “SA” suffix, registered office, share capital, share structure, and purpose.

2. Open a compte de consignation (capital deposit account) — a Swiss bank holds the paid-in capital until the company is registered. Geneva and Vaud banks are accustomed to this process for SA formations.

3. Notarial deed (acte authentique) — a licensed notary in the canton of registration conducts the constituent assembly. The notary verifies the Déclaration Stampa (confirming no hidden contributions in kind) and prepares the procès-verbal (minutes).

4. File with the Registre du Commerce — the cantonal register processes the application. Geneva typically completes registration within 5–10 business days after submission. Vaud averages 7–12 business days.

5. Receive the extrait du registre du commerce — the official extract confirming the SA’s existence. Equivalent to the German Handelsregisterauszug.

Formation Costs (Romandie, 2026)

The share capital deposit (minimum CHF 50’000) is not an expense — it belongs to the company after registration.

Cantonal Differences: Geneva vs Vaud vs Zurich

Choosing a canton for your SA or AG is a business decision, not a legal one. The entity type is identical everywhere. What varies: tax rates, registration speed, and the local business ecosystem.

Geneva suits businesses connected to international organisations, commodity trading, or French-speaking markets. The canton hosts major trading houses (Trafigura, Mercuria, Gunvor) and offers proximity to France and the broader Francophone world.

Vaud offers a lower tax burden than Geneva while remaining French-speaking. The Lausanne–EPFL corridor attracts technology companies. Nestlé, Philip Morris International, and Logitech are headquartered here.

Zurich has the lowest tax rate of the three and the deepest talent pool. If your business does not specifically require a French-speaking environment, Zurich’s financial infrastructure and airport connectivity are hard to match.

SA for International Businesses

Foreign entrepreneurs searching for “SA Switzerland” often come from French-speaking jurisdictions — France, Belgium, Luxembourg, West Africa, or Quebec. The term Société Anonyme is familiar to them. Here is what matters when choosing between a Romandie SA and a German-speaking AG.

When Geneva (SA) Makes Sense

• Your clients or partners operate primarily in French
• You trade commodities, work with UN agencies, or interact with Geneva-based international bodies
• Your management team speaks French and will attend board meetings in French
• You want a registered office in a globally recognised city with direct flights to Paris, Brussels, and major African capitals

When Zurich (AG) Makes Sense

• Your priority is the lowest available tax rate among major Swiss cities
• You need access to Swiss-German banking relationships and the Zurich financial centre
• Your business is in technology, fintech, or asset management where the Zurich ecosystem dominates
• You plan to hire from the larger German-speaking talent pool (5.3 million vs 2 million French-speaking residents)

What Does Not Change

Regardless of canton or language, the following remain constant:

• Federal company law applies uniformly (Code of Obligations)
• The entity is recognised internationally as a Swiss corporation
• Tax treaties signed by Switzerland apply to all SA and AG entities equally
• The SA/AG can open bank accounts at any Swiss bank, in any canton
• Shareholders and board members may be of any nationality

Choosing Between SA and AG: A Summary

The decision is not SA versus AG — they are the same thing. The real decision is which canton best serves your business objectives.

If you operate primarily in French, deal with French-speaking clients, or want a Geneva address, register an SA in Romandie. If tax optimisation and the German-speaking business ecosystem matter more, register an AG in Zurich, Zug, or Lucerne. In either case, you hold the same legal entity under the same federal law.
