What is withholding tax – and who does it apply to?
If you work in Switzerland and hold a B residence permit, your salary is taxed at source – this is called withholding tax or tax at source.
Your employer deducts the tax directly from your salary and pays it to the cantonal tax authorities.

How do I file a tax return with a B permit?
Submit a request for ordinary taxation by March 31 of the following year. Without this request, voluntary filing isn’t possible.
How do I know if I meet the threshold to file?
Use our B Permit Tax Calculator to check your cantonal limits easily.
Can I reclaim already paid withholding tax?
Yes – if your municipal tax rate is lower than the flat rate deducted, a tax return can help you get money back.
I work in Switzerland but live abroad. What applies to me?
You’ll likely still pay Swiss withholding tax.Report changes like family status, children, or home office setup to your employer – it affects your tax.
What happens the year I move to Switzerland?
Your Swiss tax liability starts on your arrival date and applies pro rata until year-end.
Can I file voluntarily, even if I earn below the threshold?
Yes – and it can be beneficial. Especially if you qualify for deductions (3rd pillar, health insurance, education, etc.) or live in a low-tax municipality.
Once I file voluntarily – am I required to file every year?
Yes. Once you’ve opted in, you’re treated as a regular taxpayer in future years.
What’s the difference between withholding tax and ordinary taxation?
Withholding tax = automatically deducted, no personalization.
Ordinary taxation = personalized, with deductions and potential refunds
What if I move to another canton during the year?
The canton you reside in on December 31 is responsible for your full tax year.
What if I permanently leave Switzerland?
Your last canton of residence remains responsible for your final return. Notify the tax office early – a final assessment will be required.

Absolutely – FIN offers personal, transparent guidance. We’ll assess if filing makes sense and how to maximize your outcome.
