Choosing a Legal Form in Switzerland: A Decision Guide

The legal form you choose affects liability, tax, capital requirements and how much administration you carry. The right answer depends on your situation.

The main options

Sole proprietorship (no capital, unlimited liability), GmbH (CHF 20,000 capital, limited liability), and AG (CHF 100,000 capital, limited liability, often chosen for scale or investor readiness).

Each form differs in setup cost, ongoing obligations and how profits are taxed. There is no single best choice, only the best fit for your plans.

The sole proprietorship is the default for solo founders, while the GmbH and AG are chosen for limited liability, investor readiness or credibility.

Beyond these three, specialised forms exist, such as partnerships and associations, but they suit specific cases rather than typical small businesses.

• Einzelfirma: simplest, personal liability.
• GmbH: CHF 20,000, limited liability.
• AG: CHF 100,000, limited liability, more prestige.

How to decide

Start from liability and capital: if you have little risk and little capital, a sole proprietorship works. If you want limited liability or plan to bring in investors, a GmbH or AG is the fit.

Think about growth and ownership next. If you plan to add partners or sell shares later, a GmbH or AG gives you a structure that supports that.

Tax is the third lens. Personal versus corporate taxation differs, and the better choice depends on your income level and canton.

Finally, consider admin appetite. A sole proprietorship runs with light formalities, while a GmbH or AG carries real reporting duties.

Get advice

An advisor can model the tax difference between personal and corporate taxation for your specific numbers and canton. The difference is often material.

They can also flag practical issues, such as the effect of the choice on your AHV status and social contributions as an owner.

A one-hour consultation is far cheaper than restructuring later. Treat the legal form decision as an investment decision, not an administrative box to tick.

Common scenarios

A solo freelancer with low risk and modest income is usually best served by a sole proprietorship. It is simple and cheap to maintain.

A founder expecting meaningful revenue, real liability exposure or future investors should lean toward a GmbH from the start.

A business planning rapid scaling, external funding or a board structure may go straight to an AG, accepting the higher capital and formalities.

Whichever you choose, document the reasoning. When circumstances change, you can revisit the decision with a clear picture of why you started where you did.
