When entrepreneurs plan a Swiss company, the first question is often deceptively simple: AG or GmbH? In practice, the answer is rarely about minimum capital alone. The legal form influences ownership, public visibility, governance, financing, succession and the future admission of investors. It should therefore be chosen as part of the overall structure rather than as an isolated administrative decision.
The legal form should follow the business model
A GmbH is often an excellent fit for owner-managed businesses, operational SMEs and structures with a limited number of shareholders. Its minimum share capital is CHF 20,000 and must be fully paid in. Shareholders are registered by name in the commercial register, which creates transparency but also makes the ownership structure publicly visible.
An AG requires share capital of at least CHF 100,000, of which at least CHF 50,000 must be paid in at incorporation. Shareholders are generally not publicly listed as shareholders in the commercial register. This can be relevant for international ownership structures, future investors, succession planning and the transfer of participations.
That does not make an AG automatically “better” or a GmbH automatically “simpler”. The decisive question is which structure fits the project and where the company is expected to be in two, five or ten years.
Capital is not the same as formation cost
One recurring misunderstanding is to treat company capital and incorporation costs as the same thing. Company capital is, in principle, an asset of the company. It is not a fee paid to authorities or advisers; after incorporation it can be used for the company’s business, subject to the legal rules on capital maintenance.
Actual formation and structuring costs sit alongside this capital: documentation, notary, commercial register, banking processes, translations, possible apostilles, domicile, accounting, VAT registration and, where required, Swiss representation. With international ownership structures, preparing KYC documentation can require more work than the notarial incorporation itself.
Looking only at the nominal capital requirement therefore gives an incomplete picture of the project.
Banking should be considered before the commercial register
One of the most practical lessons from international mandates is that a registered company is not automatically operational. A business bank account, appropriate payment channels and a documented source of funds can be just as important as the commercial register entry.
Banks review not only the company but also its beneficial owners, residence, business model, source of wealth and funds, expected transactions and countries involved. The more international the structure, the more important consistent documentation becomes. A business model that cannot be explained clearly in a few sentences will almost always generate additional questions.
It is therefore sensible to understand the required banking relationship and likely documentation before incorporation. This reduces delays and avoids a formally established company waiting weeks for its operating infrastructure.
Swiss representation is a governance issue
Both a GmbH and an AG must be capable of being represented by at least one authorised person resident in Switzerland. For a GmbH this may be a managing director or director; for an AG it may be a board member or director.
For international founders this requirement should be addressed early. It is not enough to satisfy the legal minimum on paper. Roles, signing authorities, actual responsibility and internal decision-making need to be coherent. A Swiss director or board member is not a decorative line in an organisational chart; the role forms part of the company’s governance.
Privacy, investors and future transferability
International entrepreneurs often ask about discretion. This should never mean opacity towards banks, authorities or contractual partners. The relevant question is which information is publicly accessible and how ownership and control are legally organised.
Where investors may later be admitted, participations transferred or different shareholder groups created, an AG often provides greater flexibility. For a closely held operating business, a GmbH may be the more direct and economical solution.
Conversions are possible later, but it is generally more efficient to consider the foreseeable development at incorporation rather than restructuring the company again a few months later.
Tax matters, but it is rarely the only criterion
Corporate taxation depends not only on legal form but also on canton, municipality, activity, ownership, financing and distributions. Both AGs and GmbHs are taxed as legal entities. Selecting a location based on one headline tax rate alone is therefore usually too simplistic.
For international owners, personal tax residence, double tax treaties, dividends, Swiss withholding tax and foreign tax rules may also be relevant. A Swiss company should be part of a sustainable overall structure rather than an isolated response to a tax rate.
What I recommend before choosing
Before deciding on the legal form, at least five questions should be answered: Who will own the company? Who will represent it? How will it be financed? Which banking and payment relationships will it require? And how should the structure be able to grow, take on investors, be sold or transferred later?
Once those points are clear, the choice between GmbH and AG becomes much easier. For me, the quality of an incorporation is not measured by how quickly a deed can be signed. It is measured by whether the company can operate afterwards without unnecessary friction.

For the legal fundamentals of AGs, GmbHs, the commercial register and Swiss representation, the Swiss Confederation’s SME Portal provides a useful official basis. The final structure should nevertheless always be reviewed in light of the specific owners, business model and countries involved.
