Illinois uses a flat income tax. One rate, 4.95%, applies to your taxable income after the state's own deductions and exemptions. It does not step up as you earn more, the way the federal brackets do. You still pay federal income tax and FICA on top, so your total tax is more than the state rate alone. Illinois taxes income at a single 4.95% rate, with no standard deduction and only a per-person exemption allowance that phases out for high earners. No state disability, paid-leave, or local wage tax is withheld, so the 4.95% rate is the full state share.
