Illinois paycheck calculator
Illinois charges one rate rather than a graduated schedule, which puts it in a small group with Pennsylvania. What separates the two is the allowance: Illinois lets a fixed sum come off the income for each one claimed on the state's certificate before the rate is applied at all.

How Illinois withholding is worked out
A single rate makes Illinois look like a state where nothing on the form matters, and that reading is wrong. The allowance is worth a substantial sum against the income, so somebody claiming several sees a visibly smaller state line than somebody claiming none on the same wage. Because the rate does not climb, an allowance is worth exactly the same number of dollars to every employee in the state, however much they earn, which is not true anywhere the rate rises with pay.
These are withholding figures: what an employer takes out of one paycheck, which is not the same calculation as the one on an annual return.
Illinois reads one schedule whatever the filing status. Wages are annualised first, so the figures below are annual.
| Annual wages | Tax on the lower figure | Rate on the rest |
|---|---|---|
| $0.00 and up | $0.00 | 4.95% |
- Exemption per allowance
- $2,925.00
Taken off the income before the schedule.
Form IL-W-4's Line 2 allowance of $1,000 is not applied here, so an employee entitled to it has less Illinois tax withheld than this line shows.
Only the $2,925 Line 1 allowance is modelled; the separate $1,000 Line 2 allowance is not.
