Illinois taxes and cost of living, explained
Illinois charges a flat state income tax of 4.95% on wages, on top of federal tax and FICA. Combined with an average sales tax of 8.98% and an average effective property tax rate of 2.07%, these figures shape most household budgeting decisions in the state — from evaluating a job offer to estimating what home you can afford.
The six calculators below all use Illinois's own current rates rather than national averages: paycheck withholding, state income tax, sales tax, property tax, a full mortgage (PITI) payment, and home affordability based on the standard 28/36 lending rule. Illinois's minimum wage is $15.00/hour, and the data behind these numbers is sourced from the Tax Foundation, WalletHub, and state revenue departments.
