Why Is the Sole Proprietorship So Popular in Switzerland?

Switzerland offers ideal conditions for self-employment: low bureaucracy, a stable economy, and tax clarity. The sole proprietorship is the easiest path to independence – especially for founders who want to start alone, stay flexible, and get going quickly.

‍

What Do I Need to Start?

To establish a sole proprietorship, you need:

• A business activity (e.g., services, trade)
• A business name (e.g., “Müller Consulting”)
• Registration with the AHV compensation fund
• A business address in Switzerland

Registration in the commercial register is only mandatory if you earn more than CHF 100,000 per year – but it can be done voluntarily to boost credibility.
