How Illinois taxes your paycheck in 2026
Illinois uses a flat tax: every dollar of taxable income is taxed at 4.95% in 2026, no matter how much you earn. Taxable income means your wages minus Illinois's deduction of $2,925 for single filers or $5,850 for married filing jointly.
On top of the state tax, your paycheck pays federal income tax (10%-37% marginal brackets) and FICA. See how the pieces interact in our marginal vs effective rate guide.
