Frequently asked questions

Do foreign residents in Switzerland need to file a tax return?

Those taxed at source may be able — or required — to file an ordinary return to claim deductions the withholding rate does not capture, such as pillar 3a contributions and professional expenses. It depends on income level and canton.

Can changing canton reduce my tax bill?

Potentially, and significantly — the income and wealth tax burden varies widely between cantons. A properly executed change of domicile is entirely legal and can generate substantial savings.
