Why do we need to know your postcode?
In Switzerland, the value of the taxes you pay depends on multiple factors:
Your income and assets
Higher income generally means higher tax rates
Your marital status
Married couples are taxed jointly with income splitting
Number of children
Children provide tax deductions
Denomination
Church tax varies by denomination and canton
Place of residence
Tax rates vary significantly between cantons and municipalities. Your postcode (PLZ) allows us to determine the exact tax rate for your location.
How it works
When you enter your postal code, we automatically look up your municipality and canton. Combined with your income and marital status, we can calculate the marginal tax rate that applies to your situation. This tax rate is crucial for accurately calculating your potential tax savings from pension optimisations.
Tax differences across Switzerland
Tax rates in Switzerland can vary dramatically depending on where you live. For example, the same income can be taxed at very different rates in Zug compared to Geneva. This is why your postcode is essential for an accurate pension calculation.
Your data is safe. We only use your postcode to calculate tax rates. We do not store your location data or share it with third parties. See our Privacy Policy for details.
