## Illinois Paycheck FAQ

Common questions about paychecks and taxes in Illinois

### What is the Illinois state income tax rate for 2026?

A flat 4.95% of Illinois net income, the rate in state law for tax years starting on or after July 1, 2017. It's the same for every filing status and every income level.

### What is the Illinois personal exemption?

$2,925 for 2026, up from $2,850 in 2025; Illinois adjusts it for inflation. Single filers, heads of household, widowed filers and married people filing separately claim one, and a married couple filing jointly claims two, $5,850. Illinois has no standard deduction. No exemption is allowed if your federal adjusted gross income is over $250,000 ($500,000 on a joint return), a cutoff the calculator doesn't apply.

### How much Illinois tax is withheld from a bonus?

Illinois lets an employer withhold on a bonus at the tax rate in effect when it's paid, 4.95%. Otherwise the bonus is withheld using the same method the employer uses for federal withholding.

### What does this calculator leave out for Illinois?

Illinois starts from federal adjusted gross income, so pre-tax deductions such as 401(k) and HSA contributions lower your Illinois tax; the calculator starts from gross wages. It applies the personal exemption at every income, so above $250,000 of federal AGI ($500,000 joint), where Illinois allows none, it shows $144.79 a year too little tax ($289.58 joint). It also leaves out dependent exemptions ($2,925 each for 2026), the extra $1,000 exemptions at 65 or older or blind, and credits such as the property tax, K-12 education expense and earned income credits. Illinois has no local income tax.
