Frequently Asked Questions
What is the Illinois state income tax rate in 2026?
Illinois uses a flat income tax rate of 4.95% on all taxable income. Unlike many states, Illinois does not use brackets — every dollar of taxable income is taxed at the same rate.
Does Illinois tax Social Security income?
No. Illinois exempts Social Security benefits, most pension income, and retirement plan distributions from state income tax, making it relatively retirement-friendly despite its flat income tax rate.
Are there local income taxes in Illinois?
Illinois municipalities generally do not impose a separate local income tax on wages. Your primary state-level deduction is the flat 4.95% plus any applicable Chicago or Cook County specific fees.
