How Swiss Income Tax Works — Bundessteuer + Kantonssteuer
Switzerland has a three-tier tax system: federal (Bundessteuer), cantonal (Kantonssteuer), and municipal (Gemeindesteuer). Federal rates are very low (max 11.5%). Cantonal + municipal rates dominate the total bill and vary enormously by location — from ~12% in Zug to ~27% in Vaud.
