How Illinois taxes wages

Illinois applies one flat rate to taxable wages on top of federal tax and FICA. The calculator applies the single-filer standard deduction, personal exemption or taxpayer credit where the state has one; dependents and other credits are not modelled, so treat it as an estimate. Details and sources are on the methodology page. Full sources and assumptions: US methodology.

Frequently asked questions

Is this Illinois calculator the same as my paycheck withholding?

No. This is the annual tax-liability view (2026 brackets and deductions). Per-paycheck withholding follows your W-4 and state withholding certificate and reconciles at filing time.

What is not included for Illinois?

Married and dependent allowances and other state credits beyond the single-filer standard deduction, exemption or taxpayer credit. Local taxes are not included. Federal figures are exact per IRS Rev. Proc. 2025-32.
