Frequently asked questions

Does Illinois have a state income tax?

Yes. Illinois has a flat state income tax of 4.95% on taxable income for 2026.

Is this calculator up to date for 2026?

Yes. It uses the 2026 federal tax brackets, the 2026 Social Security wage base, and each state's latest official rates. It estimates the tax you'll actually owe, and an optional withholding mode estimates what your employer takes out of each paycheck.
