Starting a business in Switzerland means working within a federal legal framework, but the steps vary depending on the canton where the business is based and the legal structure you choose. Before considering strategy or financing, two key decisions shape everything that follows: the company’s legal structure and the canton where it will be domiciled. These choices determine your tax treatment, accounting obligations and the capital you need to raise from the outset.
Digital compliance and AI: a blind spot for new entrepreneurs in Switzerland
Most business start-up guides stop at administrative formalities. Yet one topic is often overlooked: digital compliance, particularly the use of generative artificial intelligence tools in day-to-day operations.
The Federal Act on Data Protection (FADP) also applies to the processing of personal data by AI systems. Entering customer contact details, contracts or trade secrets into a consumer-grade tool raises questions about confidentiality and transparency. The National Cyber Security Centre recommends setting internal rules that specify which tools are permitted and what information must never be entered into them.
For a start-up SME, adopting these practices from day one avoids having to restructure processes once the business is up and running. In practical terms, this means drafting a digital tools usage policy before hiring the first employee. On Startup Café’s business website, you’ll find several resources to help structure this thinking alongside your business plan.
Legal structures in Switzerland: GmbH, AG or sole proprietorship
Choosing a legal structure is not just another administrative formality. It determines the amount of start-up capital required, the founder’s personal liability and the level of accounting requirements.
Sole proprietorship
The simplest structure. There is no minimum capital requirement, and registration in the commercial register is mandatory only once annual turnover exceeds a certain threshold. The downside: the founder is personally liable for the business’s debts. This structure is suitable for service businesses with low financial risk.
GmbH (limited liability company)
A GmbH requires minimum share capital and a visit to a notary to draw up the articles of association. The shareholders’ liability is limited to their contributions, protecting their personal assets. Most Swiss SMEs choose this structure.
AG (public limited company)
An AG requires more capital and a more complex governance structure (a board of directors and, in some cases, an auditor). It is suited to projects that require fundraising or may open up their share capital to investors in the future.
- Sole proprietorship: unlimited liability, no minimum capital, ideal for testing a concept on your own
- GmbH: liability limited to contributions, notarisation required, the most common structure for SMEs
- AG: higher capital requirement, formal governance, suited to high-growth projects or those with multiple investors
Commercial register and cantonal requirements
Registration in the commercial register formalises the company’s legal existence. For a GmbH or AG, registration is mandatory. For a sole proprietorship, it becomes mandatory once turnover exceeds a certain threshold.
The process is handled by the commercial register in the canton where the company is based. The EasyGov.swiss portal, supported by SECO, centralises some of the procedures and lets you submit documents online. Each canton has its own processing times and fees.
One point that is often underestimated: the choice of canton directly affects your tax burden. Corporate profit tax rates vary considerably from one canton to another. Domiciling your company in one canton rather than another can make a significant difference to your annual tax bill, even at the same level of profit.
Business survival rates: what the statistics reveal
Starting a business is relatively straightforward in Switzerland. Keeping it going is another matter. The Federal Statistical Office (FSO) publishes business demography data covering new business formations, survival rates and bankruptcies.
These statistics help you assess a project in its local economic context, not just at the national level. The FSO breaks down the data by business size, legal structure, industry and region. A service business in Zurich does not face the same prospects as a retail business in a rural canton.
Checking survival rates in your sector and canton before getting started is a step few entrepreneurs take. Yet this information can guide practical decisions, such as how much cash to set aside, how long it may realistically take to become profitable, and whether to choose a sole proprietorship or a GmbH to limit personal risk.
Accounting and compliance from the first financial year
Accounting is not something to deal with “later”. Requirements vary depending on the legal structure you choose.
- A sole proprietorship can keep simplified accounts (income and expenses) if its turnover stays below a certain threshold
- A GmbH or AG must prepare annual financial statements in accordance with the Swiss Code of Obligations, including a balance sheet, income statement and notes
- Some AGs that exceed certain size thresholds are subject to an ordinary audit by an external auditor
Setting up accounting software suited to Swiss law in the first month of business helps avoid costly catch-up work at year-end. Some cantons also offer free advice sessions for new entrepreneurs through their cantonal economic development services.
Switzerland’s framework offers genuine flexibility for starting a business, but that flexibility comes with clear responsibilities from day one. The legal structure, canton of domicile and sound accounting practices from the outset are the three factors that distinguish sustainable ventures from businesses that struggle in their first few years.
