Taxes in Illinois
Illinois makes payroll math easy by using a flat state income tax rate of 4.95%. This means every dollar of your taxable income is taxed at the same rate, regardless of how much you earn. For 2026, the personal exemption allowance has increased to $2,925 per person. This amount is subtracted from your gross wages before the state tax is calculated, effectively lowering your tax bill. Unlike some neighboring states, Illinois does not have local city or county income taxes, though it’s worth noting that property and sales taxes in the state are often higher to compensate.
All Illinois employees are also subject to Federal Income Tax and FICA (Social Security and Medicare) withholdings.
Federal and FICA Pillars in Illinois

Federal taxes usually take the biggest chunk of your check, following the progressive IRS brackets (10% to 37%). For 2026, the federal standard deduction is $16,100 for single filers, providing a large tax-free cushion before federal withholding even begins.
