New Arrivals

You have just moved to Switzerland and need to understand the Swiss tax system?

We also explain how withholding tax works and the registration procedures with the cantonal tax authority.

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.
