Wisconsin uses a graduated income tax system. Depending on your income bracket, residents of Salem Lakes face a rate between 3.5% and 7.65% — making the headline 4.5% figure a useful benchmark but not the full story for higher earners.
Property taxes are applied to assessed value, not market value. Illinois assesses residential property at roughly 33% of market value, Indiana at 100%, and Wisconsin assessment practices vary by municipality — which changes the real effective tax burden even when stated rates look similar.
