You work in Switzerland but don't have a Swiss passport or a settlement permit (C permit)? Then withholding tax is deducted directly from your salary - before the money even reaches your account. For many foreigners, this is their first encounter with the Swiss tax system.
In this guide, we explain everything you need to know about withholding tax 2026: who pays, how much is deducted, which tariff codes exist, how cantons differ - and when you can get money back through a subsequent ordinary assessment (NOV).
What Is Withholding Tax?
Unlike Swiss nationals who file annual tax returns and receive a tax bill, withholding tax is collected "at the source." Your employer deducts the tax amount monthly from your gross salary and transfers it to the relevant cantonal tax authority. You receive a net salary with taxes already deducted.
Withholding tax is not an additional tax. It replaces the regular income tax. You don't pay double - just through a different channel.
Who Pays Withholding Tax?
Foreign Employees Residing in Switzerland
You're subject to withholding tax if you live and work in Switzerland but don't hold a settlement permit (C permit):
- Permit B (residence permit) - the most common category
- Permit L (short-term permit) - fixed-term employment
- Permit F (provisionally admitted) - if employed
Cross-Border Commuters
- Permit G - special flat-rate tariffs (e.g., 4.5% for German cross-border commuters)
Tariff Codes: A, B, C, H and G
| Code | Meaning | Applies To |
|---|---|---|
| A | Single, no children | Unmarried, divorced, widowed without dependents |
| B | Married, sole earner | Couples where only one partner works in Switzerland |
| C | Married, dual earner | Couples where both partners are employed |
| H | Single parent | Single parents with minor children in same household |
| G | Cross-border commuter | Special flat-rate tariffs for cross-border workers |
Check your tariff code on your very first payslip. Errors happen regularly - a wrong code can cost you hundreds of francs per month.
How Much Is Withholding Tax? Examples
Example: Single in Zurich (Tariff A0), CHF 6,000/month
Plus social security deductions (AHV/IV/EO, ALV, BVG) which are deducted separately.
Example: Cross-border commuter from Germany (Tariff G), CHF 7,000/month
German cross-border commuters pay a flat 4.5%. Main taxation occurs in Germany.
Subsequent Ordinary Assessment (NOV): Getting Money Back
Withholding tax is based on flat rates. Your actual deductions (Pillar 3a, training, commute, insurance premiums) are not automatically considered. The NOV allows you to file a regular tax return and reclaim overpaid taxes.
When Is NOV Mandatory?
From a gross annual salary of CHF 120,000, you're automatically required to file. Also mandatory if you have additional income or assets subject to wealth tax.
When Does Voluntary NOV Pay Off?
- You contribute to Pillar 3a (max CHF 7,258)
- You have high professional expenses (training, long commute)
- You made a BVG pension fund buy-in
- You pay alimony
- You had high medical or dental costs
The NOV application is irrevocable. If the ordinary tax calculation is higher than the withholding tax, you must pay the difference. Calculate beforehand whether the NOV benefits you.
