How Illinois Payroll Taxes Work
Illinois uses a flat state income tax rate of 4.95%, applied to all taxable income equally regardless of how much you earn. Unlike progressive states, every dollar of income is taxed at the same rate - making paycheck calculations straightforward and predictable.
On top of the state flat tax, federal income tax applies using the standard 2026 marginal brackets (10% to 37%), plus Social Security at 6.2% on wages up to $184,500 and Medicare at 1.45% on all earnings.
Pre-tax deductions like 401(k) contributions and employer health insurance reduce your Illinois taxable income the same way they reduce your federal taxable income, giving you additional savings on both layers simultaneously.
