Swiss AG vs GmbH: Which Legal Form Is Right for Your Swiss Business?

The right structure depends on your business. Neither structure is universally better: the right choice depends on how you plan to finance, own and grow your business. For most small businesses, consultants and early-stage companies, a Swiss GmbH is the more practical starting point, as it requires less initial capital. For businesses planning to raise external investment, issue shares to multiple parties, or where shareholder privacy matters, a Swiss AG is often the better choice. Both structures offer limited liability and are widely recognised internationally, but they differ significantly in capital requirements, governance, ownership flexibility, shareholder privacy and suitability for different stages of business growth.

In English, the AG is broadly comparable to a corporation or limited company (Ltd), while the GmbH is broadly comparable to a limited liability company (LLC). Across Switzerland, these legal forms are known by different names depending on the official language of the canton. An AG is referred to as a Société Anonyme (SA) in French-speaking cantons and a Società Anonima (SA) in Italian-speaking cantons, while a GmbH is referred to as a Société à responsabilité limitée (Sàrl) in French-speaking cantons and a Società a garanzia limitata (Sagl) in Italian-speaking cantons. Throughout this guide, the German abbreviations AG and GmbH are used because they are the most widely recognised in an international business context.

This guide explains the key differences between the two structures and helps founders identify which is the right choice for their specific situation. For many businesses, the key factors are the amount of capital available at incorporation, whether external investors are planned, and how the company is expected to develop over time.

In Short

Choose a GmbH if you want the lowest capital requirement and expect stable ownership. Choose an AG if you plan to raise investment, issue shares or prioritise shareholder privacy.

Swiss AG vs GmbH: The Key Differences at a Glance

While the table below provides a quick comparison, the sections that follow explain when each structure is likely to be the better choice in practice.

What Is a Swiss GmbH?

A Swiss GmbH is a limited liability company with a minimum share capital of CHF 20’000, which must be fully paid in at incorporation. It is the legal form most commonly chosen by small and medium-sized businesses, consultants, trading companies and foreign entrepreneurs establishing a Swiss presence for the first time. While the lower capital requirement makes it an attractive starting point, its ownership structure is generally less flexible than that of an AG where frequent ownership changes or external investors are expected.

Key characteristics of a Swiss GmbH:

• Share capital divided into quotas (Stammanteile), which are not freely transferable
• All shareholders (Gesellschafter) are listed by name in the Commercial Register and are publicly visible
• Transfer of quotas generally requires a written assignment agreement and shareholder approval, unless the Articles of Association provide otherwise
• The company must be represented by at least one person resident in Switzerland, who may be a managing director or another authorised signatory
• Shareholder resolutions are governed by the voting and majority requirements set out in the Swiss Code of Obligations and the Articles of Association

What Is a Swiss AG?

A Swiss AG is a joint-stock company with minimum share capital of CHF 100’000. At least 20% of the nominal value of each share must be paid in at incorporation, and the total paid-in amount must be at least CHF 50’000. For example, an AG with share capital of CHF 500’000 would require at least CHF 100’000 to be paid in before registration.

The AG is commonly chosen by businesses seeking external investment, planning long-term growth or operating within larger corporate groups. It offers greater flexibility in ownership, governance and capital structure than a GmbH, making it the preferred vehicle for many investor-backed and internationally focused businesses.

For international founders, the AG is the Swiss legal form most comparable to a limited company in the United Kingdom, a société anonyme in France or Belgium, or a corporation in the United States. As a result, it is often the most familiar structure for international investors and corporate groups.

Key characteristics of a Swiss AG:

• Share capital divided into shares (Aktien), which are generally easier to transfer, although restrictions may exist under the Articles of Association or shareholders’ agreements
• Shareholders are not publicly named in the Commercial Register; board members and other registered authorised signatories are publicly visible
• The company must be represented by at least one person resident in Switzerland, who may be a board member or another authorised signatory
• Greater flexibility in governance, including the possibility of creating different share classes with different voting or economic rights

Which Structure Is Right for Your Business?

Choose a GmbH if you are a startup with limited capital.
The CHF 20’000 minimum capital requirement is significantly lower than the CHF 100’000 required for an AG. Since both structures have broadly similar setup and running costs for standard structures, the main financial difference at incorporation is the capital amount itself. Once the company has been registered and the capital released, the funds belong to the company and may be used for legitimate business purposes.

Choose a GmbH if the owners will actively manage the business.
A GmbH is often well suited where a small number of owners will remain closely involved in the company’s day-to-day management. Its ownership and management structure is designed for businesses in which the relationship between the shareholders matters and ownership is not expected to change frequently. This makes it a natural choice for owner-managed consultancies, agencies, trading businesses and other privately held SMEs.

Choose a GmbH if you are starting a family business or want closed ownership.
The restrictions on transferring quotas help maintain control over ownership, making it less likely that interests pass to third parties without the consent of the existing shareholders. Similar protections can be designed for an AG through its Articles of Association and shareholders’ agreement, but the GmbH starts from a more ownership-restrictive statutory model.

Choose an AG if you want to raise external investment or plan multiple investment rounds.
Shares in an AG are generally more easily transferable, making it straightforward to issue new shares to investors or transfer ownership without requiring the consent of all existing shareholders. An AG can also issue different classes of shares with different voting rights or economic entitlements, for example preference shares with priority dividend rights or shares with enhanced voting power. Most professional investors are familiar with the AG structure; a GmbH, with its quota-based ownership model and transfer restrictions, is generally less flexible for institutional investors and may create complications in due diligence processes.

Choose an AG if shareholder privacy matters.
In a Swiss GmbH, all shareholders are listed by name in the Commercial Register, which is publicly accessible. In a Swiss AG, shareholders are not publicly named in the Commercial Register. Board members and other registered authorised signatories are publicly visible. Share ownership is recorded in the company’s internal share register, which is not accessible to the general public.

An AG therefore offers greater privacy from the general public, although it does not provide complete anonymity. The company must maintain the legally required ownership records, and shareholders and beneficial owners must be disclosed to banks, authorities and other entitled parties where applicable. In addition, Switzerland’s new federal beneficial-owner transparency regime is scheduled to enter into force on 1 October 2026. The transparency register will be accessible to specified authorities and persons subject to Swiss anti-money-laundering legislation, rather than to the general public.

Choose an AG if you plan to sell shares or exit.
The generally easier transferability of AG shares makes the sale of a stake, whether partial or complete, a more straightforward process. The share structure can also be designed to facilitate future transactions, for example through appropriate share classes or, where the statutory conditions are met, a capital band authorising the board to adjust the share capital within limits approved by the shareholders.

Transferring quotas in a GmbH generally requires a written assignment agreement, approval by the shareholders’ meeting unless otherwise provided in the Articles of Association, and an update to the Commercial Register. This creates more procedural friction than transferring AG shares.

Choose an AG if your business requires higher credibility or licensing.
Due to its higher minimum capital and more formal governance structure, an AG is often perceived as carrying greater institutional credibility. This can be relevant when dealing with larger corporate clients, financial institutions, regulated counterparties or international business partners. Certain regulated activities require a specific legal form. For example, some financial institutions and insurance businesses must be organised as an AG or another legally permitted form, depending on the applicable licence. Founders should confirm the exact structural requirements with the relevant regulator before incorporation.

Choose an AG if you are establishing a holding company.
Holding companies frequently adopt the AG structure because it provides greater flexibility for managing investments, issuing shares, admitting new shareholders and reorganising ownership within a corporate group. The AG is also the structure most commonly encountered in international group structures.

A privately owned holding company with stable ownership and no planned investors may nevertheless operate effectively as a GmbH. The appropriate form depends more on the ownership and financing strategy than on the fact that the company is a holding company.

Choose an AG if you plan to offer employee equity.
Shares are generally easier to issue, transfer and manage than GmbH quotas, making employee share participation plans and stock option arrangements generally simpler to implement in an AG. This is one of the reasons early-stage companies with ambitious hiring plans frequently choose an AG.
