Why do we need to know your postcode?
In Switzerland, how much tax you pay depends on several 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 give rise to tax deductions
Denomination
Church tax varies by denomination and canton
Place of residence
Tax rates vary significantly between cantons and municipalities. Your postcode lets us determine the exact rate for your location.
How it works
When you enter your postcode, we look up your municipality and canton automatically. Combined with your income and marital status, we can determine the marginal tax rate that applies to you. That rate is what makes the tax savings from pension optimisations accurate.
Tax differences across Switzerland
Swiss tax rates vary dramatically by place of residence — the same income can be taxed very differently in Zug than in Geneva. This is why your postcode matters for an accurate pension calculation.
Your data is safe. We use your postcode only to calculate tax rates. We do not store your location data or share it with third parties. For details see our Data Protection.
