Methodology

Tax tables and multipliers are based on publicly available Swiss federal and canton data sets. Blog and guide pages are editorial content maintained in the repository.

Gross salary is annualized, social insurance is applied, then federal/cantonal/communal/church components are calculated with tariff and multiplier rules.

Employer-specific payroll rules, optional deductions, and personal tax rulings can change final results. Treat outputs as planning estimates.

We refresh tax data when official updates are available and document meaningful model changes in versioned project files.
