The first payslip should therefore be treated as a compliance document, not just a bank-transfer receipt.
Withholding tax: who is commonly affected
Foreign employees who are tax resident in Switzerland and do not hold a C settlement permit are commonly subject to tax at source, with the employer deducting the amount from salary and remitting it to the canton.
For the surrounding context, see Swiss payroll.
There are also source-tax cases for people who are not Swiss tax resident but earn Swiss-source employment or other specified income. Cross-border cases require separate treaty analysis and are not reduced to one national Swiss rate.
Your payroll position also sits inside the wider Swiss tax system, especially where withholding is followed by an ordinary assessment.
Why there is no single Swiss withholding-tax percentage
The cantons administer source tax. The rate/code can depend on matters such as:
- canton of competence;
- gross salary and type of payment;
- marital status;
- children;
- spouse/partner earning status;
- church-tax status where relevant;
- changes during the year.
That is why a colleague’s percentage is not a reliable estimate of yours.
If this decision changes the viability or sequence of your move, a Swiss relocation strategy consultation can apply it to your own facts.
Social-insurance deductions are separate
For employees, AHV/IV/EO contributions are split between employer and employee under the statutory system. The source material uses a 10.6% combined AHV/IV/EO rate, i.e. 5.3% employee and 5.3% employer, before other payroll contributions.
For the surrounding context, see cantonal withholding tax.
Unemployment insurance is also charged under its own rules; the source material uses 2.2% combined up to CHF 148,200, split between employer and employee.
Accident insurance, occupational pension and other payroll items can add further deductions depending on age, salary, employer plan and coverage.

A source-tax deduction may not be the end of your tax return
Depending on income, assets, personal circumstances and canton, a person taxed at source can still enter a subsequent ordinary assessment process or have filing/adjustment rights and obligations.
For internationally mobile employees, foreign income, securities and property can make the year-end position much more complex than the monthly payslip suggests.
Treat payroll withholding as a collection mechanism, not as proof that your entire tax position is finished.
