Starting a business in Switzerland, specifically in the canton of Basel-Landschaft, requires compliance with federal, cantonal, and municipal obligations ranging from registration in the commercial register to pension and tax requirements. Switzerland does not have a centralized business administration model: each canton manages its own commercial register according to common federal principles, but with modalities and deadlines that can vary slightly from territory to territory.

The first mandatory step is registration with the cantonal commercial register. This register is public and tracks all individual businesses, general partnerships, limited partnerships, limited liability companies, and corporations. Without registration, the activity is not legally recognized, and the owner risks administrative penalties. The Swiss tax system is structured in three levels: the federal direct tax (managed by the Federal Customs Administration), cantonal taxes, and municipal taxes (applied as a multiplier on the cantonal tax base). For those exercising an independent commercial or professional activity, taxes are calculated on the net income derived from accounting.

But taxation is only part of the obligations. Those who open a business with employees must immediately register themselves and their collaborators in the federal social security system. This means affiliation with AHV/AI with contributions of 5.3% for the employee and 5.3% for the employer (total 10.6% on gross salary). If the income from independent activity exceeds federal thresholds, the obligation to register with the BVG (professional pension fund) is triggered, with contributions ranging from 7% in the 25-34 age group to 18% for collaborators over 55 until the reference age.

Those who hire employees must also pay unemployment contributions (AL, 1.1% up to the annual maximum) and accident insurance (UVG, 0.7-1.5% depending on the sector of activity). Health insurance (KVG) is mandatory for all residents in Switzerland, regardless of professional status, and provides deductibles from CHF 300 to CHF 2500 for adults based on the customer's choice.

Choosing the legal form

The legal form significantly impacts personal liability, accounting obligations, and tax burden. An individual business entails unlimited liability of the owner to creditors but is the simplest form administratively and does not require a minimum paid-in capital. A limited liability company requires minimum capital and entails liability limited to the paid-in capital. A corporation is suitable for larger businesses and requires significant capital. The choice of legal form must also consider accounting obligations, the desired liability regime, and the expected tax burden. Each legal form has different implications on the three levels of taxation and registration with the cantonal office.

Operational details

The costs and tax levels

Anyone starting a business in Switzerland faces a tax structure with three levels, each managed by different authorities. At the federal level, the Federal Customs and Tax Administration collects the federal direct tax, calculated as a percentage of the net income of the business. Income is also subject to value-added tax (VAT), a federal tax on turnover, if the annual turnover exceeds certain federal registration thresholds.

At the cantonal level, the canton of Basel-Landschaft applies its own direct tax rate according to its tax legislation. At the municipal level, the municipalities of the canton apply a multiplier to the cantonal tax base, which means that two different municipalities in the same canton can have slightly different taxes. The exact amount of municipal tax therefore varies depending on whether the business is located in Liestal, Waldenburg, Buckten, or other municipalities of Basel-Landschaft. This system allows municipalities to have some fiscal autonomy but requires the taxpayer to check the specific rates in the chosen municipality.

Social security obligations for the owner and employees

If an entrepreneur works alone as a sole proprietor without employees, they are still obliged to pay AVS/AI contributions on a quarterly or annual basis. The rate is 10.6% of net income (the owner pays both the employee and employer portions), up to a federal coordinated income ceiling set and indexed annually.

If the business involves employees, the calculation becomes significantly more complex. For each employee, the employer pays monthly:

• 5.3% for AVS/AI
• 5.3% for IPG (loss of earnings compensation)
• 1.1% for unemployment insurance (AD) up to the annual ceiling
• 0.7-1.5% for accident insurance (LAA), depending on the sector of activity

Additionally, if an employee's coordinated salary exceeds the federal threshold for pension fund registration (an annually indexed figure), the employer is obliged to enroll the employee in the LPP/BVG (professional pension fund) system, paying contributions that vary according to the age bracket: 7% (25-34 years), 10% (35-44 years), 15% (45-54 years), 18% (55+ until the reference age). If the salary remains below the coordination threshold, enrollment in the LPP is not mandatory by law, although the employer can offer a voluntary pension solution.

Each employee must also subscribe to private health insurance (LAMal), with deductibles ranging from CHF 300 to CHF 2500 according to personal choice. This is a mandatory individual insurance by law, not a salary contribution deducted by the employer. Many employers negotiate collective rates with health insurance companies for their employees, reducing their premium.

How to register a business in Baselland: the step-by-step procedure

The procedure for opening a business follows a standard path throughout Switzerland, with minor variations depending on the canton and the chosen legal form. Here are the concrete steps:

Step 1 – Choose legal form and verify name

Before proceeding, it is essential to define the legal form (sole proprietorship, limited liability company, joint-stock company, cooperative, etc.). Once defined, verify the availability of the name with the cantonal commercial register office of Baselland. The name cannot be identical to already registered businesses in the same canton and must not violate naming regulations. If you choose a form that requires minimum capital (such as a limited liability company), ensure the capital is deposited with a banking institution within the federal deadlines.

Step 2 – Registration with the cantonal commercial register

Contact the commercial register office of the canton of Baselland. You will need to submit: the official registration form (available at the office or online on the cantonal website), identity documents of the owner or legal representative, articles of association and statutes for corporate forms, capital deposit certificate (if required by the legal form), documentation of the business premises (lease agreement, ownership or loan agreement). Once registered, you will receive a business identification number (IDI) assigned by the Federal Statistical Office, similar to a federal business tax code.

Step 3 – Registration with the AVS system and social security

Simultaneously or immediately after registering with the commercial register, register with the competent AVS compensation fund for the canton of Baselland. You will need to declare the estimated net income of the business for the correct payment of contributions. If the income exceeds the federal coordination threshold, you will need to simultaneously subscribe to the pension fund (LPP) with an authorized professional insurance. If you hire employees, register them with the same AVS fund and pay monthly contributions for both AVS/AI and unemployment and accident insurance.

Step 4 – VAT registration (if applicable)

If the estimated turnover exceeds the federal mandatory registration threshold, register for VAT with the federal tax administration (VAT Office). If you remain below the threshold, you can choose voluntary registration to recover VAT on business purchases. This decision has significant tax implications and it is advisable to evaluate it with a professional.

Step 5 – Annual tax obligations and payments

Each year, declare the net income of your business through the federal income tax return (with the Federal Customs Administration) and the cantonal return with the tax administration of Baselland. If you are subject to VAT, you will pay balances periodically based on quarterly or annual declarations according to the chosen regime. If you have employees, you will also need to declare the salaries paid and social contributions annually. Typical deadlines are: VAT declaration every quarter (or year according to the regime), federal and cantonal income tax return by March 31 of the following year, AVS contribution payment by the 5th of the month following the calculation period.

Essential documents to prepare

For each legal form, previously assemble: valid identity document of the owner, civil registry extract (for sole proprietorships), signed articles of association and statutes (for companies), capital deposit certificate with a Swiss bank (for forms that require it), lease agreement or ownership deed of the business premises. Having these documents ready significantly speeds up the registration process and avoids administrative delays.
