Rights of Expatriates and International Workers in Switzerland

Tax for Expats: Withholding Tax and NOV

Foreign employees without Permit C are subject to withholding tax (Quellensteuer): the employer deducts tax at source monthly. The rate depends on canton, salary level, family situation and (for cross-border workers) home country. Since 2021, residents with Permit B or G and Swiss domicile can request a subsequent ordinary assessment (NOV) to claim deductions not reflected in the withholding rate (e.g. commuting costs, pension contributions, professional expenses). Mandatory NOV applies if annual income exceeds CHF 120,000. Cross-border workers are taxed differently under each bilateral double-taxation treaty.

Social Insurance and Pension Portability

EU/EFTA employees are subject to Swiss social security (AHV, ALV, UVG, BVG) from the first day of work. Cross-border workers stay covered by their home country's health insurance (EU coordination). AHV contributions build Swiss pension rights, upon leaving Switzerland, EU/EFTA citizens can export AHV rights. BVG capital portability: EU/EFTA citizens may only withdraw the over-mandatory portion upon leaving Switzerland; the mandatory portion stays until retirement. Third-country nationals may withdraw their full BVG capital upon permanent departure.

Foreign Qualification Recognition and Language

For regulated professions (medicine, pharmacy, engineering, teaching), foreign qualifications must be officially recognised (SBFI, MedReg, EDK). For non-regulated professions, qualifications are assessed by employers. EU diplomas are recognised via the AFMP procedure (faster). Swiss employers in international environments accept English CVs, for German/French/Italian-speaking roles, language proficiency (minimum B2) is typically required. Cantonal integration services offer free language courses for residents.

Frequently Asked Questions

Do I pay more tax as an expat in Switzerland than Swiss citizens?

Not necessarily, withholding tax rates are designed to approximate the ordinary tax burden. However, you may miss out on deductions automatically available in ordinary assessment. Requesting a NOV allows you to claim these deductions. Permit C holders file ordinary tax returns like Swiss citizens.

Can I take my Swiss pension back to my home country when I leave?

AHV contributions: you can withdraw contributions if you leave Switzerland and your home country has no social security agreement with Switzerland. EU/EFTA citizens generally cannot withdraw AHV but retain future pension rights. BVG (pension fund): EU/EFTA citizens can only withdraw over-mandatory capital; non-EU/EFTA citizens can withdraw the full amount.

What is the Posted Workers Act (EntsG) and does it affect me?

If you are sent to work in Switzerland by a foreign employer (posted worker), the Swiss Posted Workers Act (EntsG) ensures you receive Swiss minimum wages, standard working conditions and social security while working in Switzerland. Your employer must register your assignment with the Swiss authorities.

What is the 13th month salary in Switzerland?

The 13th month salary in Switzerland refers to an additional monthly salary paid once a year, typically in December. It is included in annual salary benchmarks as standard: when a Swiss employer quotes CHF 120,000 per year, this normally means 13 monthly payments of approximately CHF 9,231 each, not 12 payments of CHF 10,000. The 13th month is governed by the employment contract or collective agreement (GAV), not by statute. It is subject to social contributions (AHV/ALV) and income tax. Always clarify with a prospective employer whether a quoted annual figure includes or excludes the 13th month.

How do Swiss notice periods work for employment contracts?

Under Swiss law (Code of Obligations, Art. 335c), notice periods during probation (default 1 month, up to 3 months by agreement) are 7 days. After probation, statutory notice periods are: 1 month during the first year, 2 months in years 2 to 9, and 3 months from year 10 onwards. Notice must be given in writing by end of calendar month (or end of the agreed notice period month). Contractual or GAV notice periods can be longer but cannot be shorter than statutory minimums. Protected periods exist (illness, accident, pregnancy) during which termination is suspended or prohibited.
