What comes out
What a Illinois paycheck actually loses
- Illinois has a single flat rate of 4.95% — there are no brackets, so a raise never pushes you into a higher state rate.
- Each allowance claimed on Form IL-W-4 Line 1 shelters $2,925 of annual wages; Line 2 allowances shelter $1,000 each. This calculator assumes one Line 1 allowance.
- Illinois has no local wage income tax, so a Chicago paycheck and a Springfield paycheck are withheld the same way.
- Federal income tax and FICA still come out of every paycheck — see the breakdown above.

Common questions
Illinois, in plain terms
Does Illinois have a state income tax?
Yes. Illinois taxes wages at a flat 4.95%, applied after an allowance or standard deduction is subtracted from your annualised pay.
How much is taken out of a $60,000 salary in Illinois?
On a $60,000 salary paid every two weeks, roughly $12,435 a year is withheld — federal income tax, Social Security, Medicare and state income tax — leaving about $47,565 in take-home pay. Your own figure depends on your W-4, pre-tax deductions and filing status.
How do I change how much is withheld in Illinois?
Federal withholding is set by your Form W-4. Illinois withholding is set separately by Form IL-W-4, which you give to your employer. Updating either one changes your next paycheck, not past ones.
Why is my real paycheck different from this estimate?
Employers can use several IRS-approved withholding methods, and your pay stub may include deductions this calculator does not know about — union dues, garnishments, employer benefit splits, local taxes or a mid-year pay change. Treat this as an estimate and check it against your stub.
