Anyone wishing to start a business in Switzerland — including in the Canton of Appenzell Ausserrhoden — must first understand the federal registration obligations, the legal form constraints, and the tax and contribution implications. The registration procedure in the commercial register is identical throughout Switzerland: it is a federal registration, although managed at the cantonal level through the official office of the canton of residence of the company.

Whatever legal form is chosen — sole proprietorship, simple company, collective name company (Snc), limited liability company (Sagl), public limited company (Sa) — the company cannot operate without registration in the commercial register (RDC). This is a federal legal obligation, not optional.

Operational details

Available legal forms

In Switzerland, there is no single "business model". The choice of legal form depends on the number of partners, available capital, desired personal liability, and acceptable administrative burden.

Sole proprietorship: A single natural person exercises the activity under their name. The responsible person is personally and unlimitedly liable for debts. No minimum capital is required. It is the simplest and least costly form, but it fully exposes personal assets to business risks.

General partnership (Snc): Two or more associated persons. Each partner is personally and jointly liable for the company's debts. Requires a conventional minimum capital. Rarely used for modern commercial enterprises.

Limited liability company (Sagl): One or more partners. Liability is limited to the paid-in capital, not personal assets. Requires CHF 20,000 minimum capital. It is the preferred form for SMEs in Switzerland for the balance between limited liability and administrative simplicity.

Corporation (Sa): One or more shareholders. Liability is limited to the paid-in capital. Requires CHF 100,000 minimum capital (CHF 50,000 if named shares). Heavier administrative structure, with shareholder meetings and boards of directors. Suitable for large enterprises or for institutional credibility needs.

Cooperatives: Association of persons with a mutualistic purpose. Limited liability. Rarely used in the context of business start-ups, more common in agriculture and collective services.

Key points

Social contributions and mandatory insurances

The employer who hires employees (or who is an employee of a company that is being founded) incurs federal contribution obligations. AVS/AI/IPG (old-age/invalidity/loss of earnings compensation): The employee pays 5.3% of the gross salary. The employer pays an additional 5.3%, for a total of 10.6%. This is one of the most significant burdens for an SME.

Unemployment insurance (AD) and Disaster insurance (AC): Payment of 1.1% up to an annual maximum, regardless of the canton.

Accident insurance (LAINF) and Occupational illness insurance (LAA): Vary by sector (0.7–1.5% of the coordinated salary). Construction, manufacturing, and agricultural companies have higher rates; offices and commerce have lower rates.

Professional pension (LPP/BVG): Mandatory if the coordinated salary exceeds the threshold (currently approximately CHF 22,050 per year; amount indexed annually). The employee pays from 7% to 18% of the coordinated salary, depending on age (7% at 25–34 years, 10% at 35–44, 15% at 45–54, 18% at 55 years until the reference age).

LAMal (mandatory health insurance): Every resident in Switzerland must take out health insurance within three months of arrival. It is not a tax, but a private insurance with per capita premiums, which vary by canton and deductible class. Consult the health insurance comparison tool to evaluate LAMal premiums in your canton of residence. Deductibles for adults range from CHF 300 to CHF 2,500 annually. The canton can provide premium reduction subsidies to low-income residents.
