Moving to Switzerland means understanding a tax system that is unique in the world: three levels of taxation (federal, cantonal, and communal), mandatory self-assessment, and rules that vary considerably depending on your canton of residence.

Your first year in Switzerland is crucial from a tax perspective. Depending on your arrival date, you may be taxed on a pro rata temporis basis for the first period. If you hold a B permit, you will initially be taxed at source, with the option to switch to ordinary taxation via the TOU if your gross income exceeds CHF 120,000.

Key tax decisions upon arrival: canton of residence (tax rates can vary by a factor of two between cantons), pillar 3a (start contributing from the very first year), vested benefits account (transfer possible from the EU/EFTA), and lump-sum taxation (for wealthy foreign nationals who do not work in Switzerland).

What we do for you: a comprehensive audit of your tax situation, selection of the optimal taxation regime, first tax return with identification of all deductions, implementation of a pension strategy (pillar 3a, LPP buybacks), and assistance with your dealings with the cantonal tax authority.

Our experience with expatriates helps you avoid costly first-year mistakes and lays the foundation for long-term tax optimization.

Frequently asked questions

When do I need to file my first tax return in Switzerland?
Your first tax return covers the period from your date of arrival to of the same year. It must be filed within the cantonal deadline (generally or of the following year). If you are subject to withholding tax, you can apply for the TOU if it is advantageous.
How does pillar 3a work for a new arrival?
You can open a pillar 3a account as soon as you arrive and contribute up to CHF 7,258 (in 2025) if you are an employee affiliated with a 2nd pillar pension fund. The full amount is deductible from taxable income. This is one of the first optimizations to set up when you settle in Switzerland.
Why is Valais a tax-attractive canton?
Valais benefits from one of the lowest cantonal tax scales in French-speaking Switzerland, with a maximum marginal rate of approximately 36% across all levels combined. Mountain municipalities such as Lens, Bagnes, and Nendaz apply particularly advantageous municipal coefficients. This attractiveness, combined with a lower cost of living compared to Geneva or Lausanne, makes it a popular destination for families and self-employed individuals seeking to optimize their tax burden.
How do I declare a property in Valais?
Property owners in Valais must declare the tax value of their property as well as the imputed rental value set by the administration. The imputed rental value corresponds to approximately 70% of the market rental value. Maintenance costs can be deducted either as actual expenses or as a flat rate (10% for buildings less than 10 years old, 20% thereafter). Mortgage interest is fully deductible, up to the limit of gross asset returns plus CHF 50,000.

Tax Declarations (Individuals)

We prepare and optimize your tax return, whether you are an employee, self-employed, or a retiree. Our expertise covers all deductions allowed by the cantonal and federal tax authorities, in order to legally reduce your tax burden. Each declaration is reviewed by a specialist before submission.

Withholding Tax & TOU

Withholding tax is deducted directly from the salary of B permit, L permit, or cross-border workers. We analyze your situation to file a Subsequent Ordinary Assessment (TOU) request when it is advantageous, which often allows you to recover several thousand francs. Since 2021, the withholding tax reform has expanded TOU eligibility for many taxpayers.

Cross-Border Taxation

Cross-border workers are subject to complex tax rules arising from the double taxation agreements between Switzerland and France. Depending on your canton of employment, you may be taxed at source in Switzerland or only in France. We guide you to optimize your situation and avoid double taxation, taking into account the Franco-Swiss agreement of April 11, 1983 and its amendments.
