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.

Key facts

What: Starting a commercial activity in Basel-Landschaft
Where: Canton of Basel-Landschaft, Switzerland
Who: Sole proprietors or companies
Legal forms: Sole proprietorship, SNC, SA, SARL, association, cooperative
Taxation: 3 levels (federal, cantonal, municipal) managed by AFC/ESTV and the cantonal administration

Starting a commercial activity in the canton of Basel-Landschaft requires knowledge of various regulatory aspects, from choosing the legal form to registration in the Commercial Register and tax and social security obligations. Switzerland has a tax system structured at three levels — federal, cantonal and municipal — each with specific rules and rates. For an entrepreneur wishing to start a business in Basel-Landschaft, the process begins with choosing the legal structure best suited to their objectives and the degree of risk they intend to assume.

The legal forms available are varied: from sole proprietorship, the simplest from an administrative standpoint, to various types of companies (general partnership, joint-stock company, limited liability company), as well as cooperatives and associations. Each choice entails different implications in terms of personal liability, minimum capital required, administrative burdens and tax treatment.

Registration in the Commercial Register is mandatory for all commercial activities and represents the first formal step. This register, managed at cantonal level, records the company’s details, its owners and any authorized representatives. The procedure is carried out through the competent cantonal office and generates a commercial registration number that identifies the business with the tax, customs and social security authorities.

The three-tier tax system

Taxation in Switzerland operates on three distinct and cumulative levels. At the federal level, personal income tax (direct federal tax) and value added tax (VAT) are administered by AFC (Federal Customs Administration). The canton and municipalities levy their own cantonal and municipal taxes, with rates and regulations specific to each territory. In the canton of Basel-Landschaft, as in all Swiss cantons, the cantonal administration defines its own taxation methods.

A crucial aspect for anyone starting a business is understanding that taxation is not a single tax, but is calculated cumulatively at all three levels. Furthermore, municipalities apply a multiplier based on the cantonal tax rate, meaning that two geographically close municipalities may have significantly different tax burdens. This multilevel structure allows each level of government to finance its own powers and responsibilities.

Operational details

Mandatory social security and insurance

Anyone who starts a business and hires employees must register with the Swiss social security and insurance institutions. The Federal Social Insurance Office (FSIO) oversees old-age and survivors’ insurance (OASI) and disability insurance (DI), which are supplemented by contributions for unemployment insurance (UI) and occupational accident insurance (UVG).

For employees, the OASI/DI/IC contribution is 5.3% of the payroll (the employer pays an additional combined contribution of 10.6%), UI is 1.1% up to an annual ceiling, while UVG ranges from 0.7% to 1.5% depending on the economic sector. The business owner must personally register with OASI as a self-employed person, while the mandatory pension fund (LPP) represents an additional obligation if the coordinated salaries exceed the federal minimum.

In addition to social insurance, every person residing in Switzerland is required to take out health insurance (KVG). This is not a tax or a payroll contribution, but private insurance with per-capita premiums set by each insurer and varying by canton and region. The canton of Basel-Landschaft, like every canton, provides a premium reduction (subsidy) for people with low incomes. The deductible for adults ranges from CHF 300 to CHF 2500 per year.

Practical implications of the legal form

The choice of legal form has far-reaching consequences for tax and insurance management. Anyone who starts a sole proprietorship remains personally liable for all debts and obligations toward creditors, tax authorities and insurance institutions. If the financial situation deteriorates, personal assets are exposed to seizures and attachments. If one opts for a company (SA or SARL), liability is limited to the capital paid in, reducing personal risk. However, companies require more documentation, annual formal obligations and higher administrative costs.

Another relevant aspect is the different tax treatment of the legal forms. A sole proprietorship is taxed on the entrepreneur’s personal income, while companies first pay corporate income tax, after which the owners pay personal tax on any profit distributions. This double taxation is nevertheless partially mitigated by deductions and special regimes provided for by cantonal and federal laws.

In the canton of Basel-Landschaft, the variability of municipal tax rates—which operate as a multiplier on the cantonal rate—means that choosing the location at municipal level is strategic for the company’s financial balance. Comparing the tax burden of different municipalities can make a tangible difference to the profitability of the business.

Key points

Step-by-step procedure

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

2. Verification of regulatory compatibility: Some activities are reserved (e.g. professional practices, pharmacies, regulated crafts) and require special authorizations or certifications. It is necessary to check with the competent cantonal office whether the planned activity is subject to restrictions or requirements.

3. Registration in the Commercial Register: Registration takes place at the cantonal office (in most cantons through the online portal). Constitutive documents for the chosen legal form, identification of the owners and representatives, and a summary declaration of expected income are required. Once registered, the company receives a commercial registration number required for all dealings with authorities and social institutions.

4. Assignment of the tax identification number: The FTA and cantonal administration automatically transmit the data from the Commercial Register to the competent authorities. The canton assigns a federal tax identification number (UID) and the commercial registration number with the cantonal administration and the municipalities concerned.

5. Affiliation with social insurance: The employer must register with the social security bodies (AVS, AD, LAINF, LPP if applicable) and communicate the start of the activity and employee data. The business owner must personally affiliate with AVS as a self-employed person.

6. Taking out health insurance (LAMal): Both the owner and employees must take out LAMal within three months of starting the activity or being hired (for employees). The choice of insurer, basic coverage and deductible model (from CHF 300 to CHF 2500 for adults) is free and has a direct impact on the company's operating costs.

Tools and support for tax management

Once registration has been completed, it is essential to keep track of federal, cantonal and municipal tax deadlines. The FTA publishes a federal calendar of VAT and IFD deadlines, while the canton of Basel-Landschaft communicates the deadlines for cantonal and municipal returns. The accounts must be kept in accordance with Swiss commercial law and made available to the tax authorities.

Many entrepreneurs rely on tax advisers, accountants or accounting management software to meet all deadlines and organize the accounts in compliance with regulations. Those wishing to explore the calculation of taxes and contributions based on expected income may find it useful to use [calculation tools (nav:calculator)] available online, which make it possible to simulate the federal, cantonal and municipal tax burden according to different income scenarios. This approach makes it possible to assess the economic feasibility of the activity and plan tax management from the outset.
