## Swiss withholding tax: a simple calculation guide for 2026

By Michael Dusong · Updated 08.11.2026

**Swiss withholding tax** is deducted by the employer from affected employees' remuneration and paid to the tax authority. One percentage chosen at the start of the year is not enough: the correct canton, tariff, personal facts and period all matter.

References and examples: **2026**.

### Collect the right information

Establish tax liability from residence, permit status and, where relevant, cross-border circumstances. Record marital status, relevant children, the spouse's employment, other jobs and effective dates. The competent canton is not always the canton of the worksite or company headquarters. [FTA Circular 45](https://www.estv.admin.ch/dam/fr/sd-web/I3YyTvU3ThVA/dbst-ks-2019-1-045-d-fr.pdf) explains the framework and special cases.

Keep evidence supporting the tariff. Unknown information should not default to “no”.

### Monthly and annual models

| Model | Principle |
|---|---|
| Monthly | The month is the calculation period, with rules for determining the rate-setting income |
| Annual | The calculation considers the annual period and previous deductions, with adjustments |

**Fribourg, Geneva, Ticino, Vaud and Valais** use the annual model. Other cantons, including Neuchâtel, use the monthly model. See [FTA Annex III](https://www.estv.admin.ch/dam/fr/sd-web/GZkIZ1vnmJmI/dbst-ks-2019-1-045-d-anhang3-fr.pdf). Both can involve monthly deductions: “annual” does not mean waiting until December to withhold tax.

### Separate taxable pay from rate-setting income

The **taxable base** is the amount to which tax applies. **Rate-setting income** determines the percentage. They may differ, especially with multiple jobs or an incomplete period. Do not simply multiply net salary by a percentage.

Teaching example only: a **CHF 5,000** base at a properly determined **6%** rate gives **CHF 300** tax. This rate is fictional, not an official tariff. A 13th salary, bonus or additional job requires checking the applicable method again.

### Before approving the payslip

- Match the official tariff to the year, canton and personal circumstances.

- Review the taxable base, rate-setting income and cumulative figures.

- Check the deduction and its effect on net pay.

- Prepare the return and payment within the canton's deadlines. [Employer obligations: Vaud example](https://www.vd.ch/etat-droit-finances/impots/pour-les-employeurs/impot-a-la-source/retenue-dimpot-a-la-source).

### How BMT makes the work easier

BMT uses imported official tax tables and links dated circumstances to periods and cumulative amounts. Missing required information is flagged before approval. **A missing tax rate is not a known rate of 0%.** You can review the taxable base, rate-determining income and deduction together.

### FAQ

#### Is a 0% rate always an error?

No. A verified official rate may be zero. A missing verified rate must not be treated as evidence that no tax is due.

#### Do two employees with identical gross pay owe the same tax?

Not necessarily. Canton, personal circumstances, other employment and period can change the rate.

#### Does a collective agreement replace the tax tariff?

No. The agreement helps determine remuneration and working conditions. Tax follows the applicable fiscal rules.

Your accounting almost runs itself.
