Swiss Annual Tax Return

Hard ~45 min TaxSwitzerlandCantonal

/ What is this form?

Switzerland levies income taxes at three levels: federal (Direkte Bundessteuer), cantonal, and municipal. Each canton has its own tax return system, rates, and deadlines. Swiss income tax is among the most complex in Europe due to this multi-level structure.

Foreigners with a B permit earning under CHF 120,000 are subject to Quellensteuer (withholding tax) and generally don't need to file a standard return. However, if you have deductions to claim (e.g., Säule 3a, mortgage) or earn above CHF 120,000, you should request a Quellensteuer correction or file a regular return.

Säule 3a private pension contributions are one of the most important deductions — up to CHF 7,056/year for employed persons is fully deductible.

/ Frequently asked questions

Do I file on Quellensteuer?

If you have a B permit and earn under CHF 120,000, you're usually taxed at source without needing to file. But if you own property, have a Säule 3a, or earn above CHF 120,000, request a Quellensteuer correction or file a regular return.
