What legal forms require minimum capital to open a business in Basel Countryside?

The sole proprietorship does not require minimum capital, while partnerships, SA and SARL require paid-in capital (specific amounts not yet declared by the canton of Basel Countryside). Cooperatives have their own requirements. The choice depends on the personal risk you want to take and the administrative burden you want to bear.

What happens if I don't register with the Trade Register?

Registration is mandatory for all business activities in Switzerland. Operating without registration exposes you to administrative sanctions, legal non-recognition of the business, absence of limited liability protection (if you choose a company) and difficulties in dealing with suppliers, customers and banks.

When do I need to take out health insurance (LAMal)?

LAMal is mandatory for all residents in Switzerland. Anyone who opens a business as an owner or hires employees must stipulate it within three months of the start of the business, under penalty of administrative sanctions. The canton of Basel-Country offers premium reductions for low-income earners.

What are the social security contributions that I have to pay as an employer?

If you hire employees, you must pay AVS/AI/IPG contributions equal to 10.6% cumulative paycheck, AD at 1.1% up to the annual ceiling, LAINF between 0.7% and 1.5% depending on the economic sector. You must affiliate employees with the pension fund (LPP) if the coordinated salary exceeds the federal minimum. As the owner, you are personally affiliated with the AVS.

Does Basel-Country have a different tax system than other cantons?

Yes, although the system on 3 levels (federal, cantonal, municipal) is the same throughout Switzerland, the rates vary by canton and by municipality. Basel Countryside has its own cantonal rates, and each municipality applies a multiplier on a cantonal basis, creating significant differences between neighbouring municipalities.

Operational details

Pension and compulsory insurance

Those who open a business and hire employees must register with the Swiss social security and social insurance institutions. The Federal Office of Social Insurance (UFAS) oversees old-age and survivors' insurance (AVS) and disability insurance (AI), to which are added contributions for unemployment insurance (AD) and against occupational accidents (LAINF).

For employees, the AVS/AI/IPG contribution is 5.3% on the payroll (the employer pays an additional cumulative contribution of 10.6%), the AD is 1.1% up to an annual ceiling, while the LAINF varies between 0.7% and 1.5% depending on the economic sector. The business owner must personally affiliate with the AVS as an independent, while the compulsory pension fund (LPP) represents an additional obligation if the coordinated wages exceed the federal minimum.

In addition to social insurance, every person residing in Switzerland is obliged to take out health insurance (LAMal). It is not a tax or a wage contribution, but a private insurance with per capita premiums set by each insurer and variables by canton and region. The canton of Basel-Country, like every canton, provides for a reduction in premiums (subsidy) for those with low incomes. The allowance for adults varies between CHF 300 and CHF 2500 per year.

Key points

# Step-by-step procedure

1. Choice of legal form : Before any other action, it is necessary to decide whether to operate as a sole proprietorship, partnership (SNC), joint stock company (SA), limited liability company (SARL), cooperative or association. This choice determines the minimum capital required, personal liability, administrative charges and tax treatment.

2. Regulatory compatibility check: Some activities are confidential (e.g. professional studios, pharmacies, regulated crafts) and require special authorisations or certifications. It is necessary to check with the competent cantonal office whether the planned activity is subject to restrictions or constraints.

3. Registration in the Trade Register: Registration takes place at the cantonal office (in most cantons through the online portal). Documents establishing the chosen legal form, identification of the owners and representatives, and a summary declaration of the expected income are required. Once registered, the company receives a business number necessary for all relations with authorities and social bodies.

4. Assignment of the tax identification number: The AFC and the cantonal administration automatically transmit data from the Trade Register to the competent authorities. The canton assigns a federal tax identification number (UID) and business number to the cantonal administration and municipalities
