How Illinois take-home pay works
Every paycheck is reduced by three things: federal income tax (2026 brackets), FICA (6.2% Social Security + 1.45% Medicare, 7.65% combined), and a flat 4.95% state income tax. Because the state rate is flat, Illinois applies the same 4.95% to every dollar of taxable income, so the state share of your paycheck is easy to predict.
