Illinois applies a flat state income tax of 4.95% to all taxable income, with no graduated brackets. Illinois has no standard deduction; instead it reduces income by a personal exemption allowance for each filer and dependent, an allowance that disappears entirely for high earners above set income limits. There are no employee-paid state disability or paid-leave premiums in Illinois, and no local wage income taxes, so the 4.95% rate is the state's whole claim on your pay. This page serves Illinois workers comparing take-home and anyone confirming how the flat rate and exemption apply to their salary; the tables below show pay across salary levels for 2026 after federal tax, FICA and Illinois tax.

Frequently asked questions
How is take-home pay calculated in Illinois?
We start with your gross salary and subtract the 2026 federal standard deduction for your filing status, then apply the federal tax brackets to what is left. FICA, the Social Security and Medicare tax, is added on the gross. On top of that comes the Illinois state layer, using Illinois's own brackets or flat rate and its deductions. The result is your estimated annual tax liability, which we divide across your pay periods to show weekly, biweekly, and monthly figures.
Does Illinois tax bonuses differently?
A bonus is withheld using supplemental wage rules, which can differ from your regular paycheck. See the Illinois bonus tax page for how the federal flat rate and the state layer apply.
Are these numbers withholding or final tax?
These are an annual tax-liability estimate, not the exact withholding from any one paycheck. The per-paycheck columns are the annual figure divided by the number of pay periods. Your employer's real withholding uses IRS payroll tables and can differ slightly, then reconciles when you file your return.
