As an expat in Switzerland, your tax obligation depends on your permit type and income. C permit holders file an ordinary tax return every year. B permit holders pay withholding tax (Quellensteuer) monthly via their employer — but must file a Nachträgliche Ordentliche Veranlagung (NOV) if gross income exceeds CHF 120000/year, with NOV mandatory under the federal harmonization in force since 2021. G and L permit holders are typically taxed exclusively at source. Source: FTA — Taxes in Switzerland. This guide explains Swiss taxes clearly, in English, with practical steps you can take today.
It depends on your residency permit:
| Permit | Tax system | File a return? |
|---|---|---|
| C permit (settlement) | Ordinary assessment (ordentliche Veranlagung) | Yes — mandatory |
| B permit (residence) | Withholding tax (Quellensteuer) | Only in certain cases (see below) |
| G permit (cross-border) | Withholding tax | Usually no |
| L permit (short-term) | Withholding tax | Usually no |
If you hold a B permit and your gross annual salary exceeds CHF 120000, you are required to file a regular tax return (Nachträgliche Ordentliche Veranlagung — NOV) in addition to paying withholding tax.
You may also voluntarily request the NOV if you have significant deductions (mortgage interest, pillar 3a, professional expenses) that could reduce your tax burden.

Withholding tax (German: Quellensteuer) is deducted directly from your salary by your employer each month. The rate depends on:
Typical withholding tax rates (Canton Zurich, 2025):
| Gross salary | Single, no children | Married, 2 children |
|---|---|---|
| CHF 60,000 | approx. 13% | approx. 8% |
| CHF 80,000 | approx. 17% | approx. 11% |
| CHF 120000 | approx. 22% | approx. 15% |
| CHF 200,000 | approx. 28% | approx. 21% |
Note: Withholding tax rates are indicative. Actual rates depend on the specific tariff code applied by your employer.
Important: Withholding tax is not final for B permit holders earning over CHF 120000. You must file a NOV and settle the difference (positive or negative).

Even if you pay withholding tax, you may be entitled to deductions that reduce your overall tax burden — but only if you request the NOV (nachträgliche ordentliche Veranlagung).
| Deduction | Amount / Rules |
|---|---|
| Commuting costs | CHF 0.70/km (car) or actual cost (public transport) |
| Meals outside home | Up to CHF 3200/year |
| Professional training | Actual cost, up to CHF 12000 |
| Pillar 3a | Up to CHF 7258/year (fully deductible) |
| Health insurance premiums | Lump sum CHF 2800 (single) / CHF 5600 (married) |
| Professional expenses | Flat rate 3% of net salary (min. CHF 2,000, max. CHF 4,000) |
| Mortgage interest | 100% deductible (if you own Swiss property) |
| Childcare costs | Up to CHF 25500 per child per year |

Restricted Stock Units (RSUs) and employee stock options are common for expats in tech, finance, and multinational companies. Switzerland taxes them differently from cash income:
RSUs:
Stock Options:
Important for B permit holders: RSU income at vesting is subject to withholding tax. However, if total income exceeds CHF 120000, the NOV will also apply.

Switzerland is unusual in taxing net wealth annually — not just income. The wealth tax (Vermögenssteuer) applies to:
Rates: Low — typically 0.1–0.7% of net wealth depending on the canton. Switzerland has one of the lowest wealth taxes in the world. Zug and Nidwalden are particularly attractive.
Tax-free allowances: Most cantons exempt the first CHF 50,000–100,000 of wealth.

Inheritance tax: Switzerland has NO federal inheritance tax. Cantonal rules apply and vary significantly. Spouses and direct descendants are exempt in almost all cantons. More distant relatives pay higher rates.
Capital gains tax: Switzerland has NO general capital gains tax on investment portfolios for private individuals. Gains from selling stocks, ETFs, or bonds are generally tax-free — provided you are classified as a private investor, not a professional trader.
Exception: Gains from selling real estate are taxed (Grundstückgewinnsteuer — property gains tax), with rates varying by canton and holding period.
