What comes out of a Illinois paycheck
On $1,500 every two weeks, single, an Illinois worker keeps $1,220.42.
Illinois has no brackets. The state taxes wages at 4.95 percent, and the only thing that varies from worker to worker is the exemption. Each basic allowance on Form IL-W-4 is worth $2,925 a year. Your employer divides the total by the number of pay periods, subtracts that from your pay, and takes 4.95 percent of what is left. If the exemption is larger than your pay for the period, nothing is withheld.
The form has no filing status. A married worker claims one allowance for themselves and one for a spouse, and each dependent adds one more. Every dependent lowers your yearly taxable wages by $2,925, which is about $144.79 less Illinois tax a year. Extra allowances worth $1,000 each cover things like age 65 or blindness, and the calculator assumes none.
Two details may surprise you. A worker who files no IL-W-4 is taxed on all wages with no exemption at all. And Illinois does not subtract your federal tax before figuring its own.
County and local taxes
Illinois leaves the local income tax question to the legislature. The state constitution lets a home rule unit tax income or earnings only if the General Assembly provides for it by law, and our search found no law that does. The IL-700-T booklet and Form IL-W-4 describe state withholding only. No Illinois Department of Revenue page says "no local income tax" in those words, so this rests on the constitution plus the absence of any grant.
Nothing local is left out of the Illinois result.
Final pay and the minimum wage
Illinois sets the minimum wage at $15.00 an hour and the tipped cash wage at $9.00 an hour, before tips.
Final pay follows one rule, fired or not. Your employer owes it in full at the time you leave if possible, and no later than the next regularly scheduled payday. The amount includes earned vacation pay, earned bonuses, and earned commissions, so check that all three appear on your last stub.

Checked on Oct 29, 2026. Source: Illinois Department of Revenue, Booklet IL-700-T, Illinois Withholding Tax Tables, effective January 1, 2026 (R-12/25), page 3: "The income tax rate is 4.95 percent and the exemption allowance is $2,925" (tax.illinois.gov/content/dam/soi/en/web/tax/forms/withholding/documents/currentyear/il-700-t.pdf, saved as data/sources/illinois/IL-700-T.pdf, read Oct 29, 2026).
Local taxes: Illinois Constitution, Article VII, Section 6(e) (ilga.gov/commission/lrb/con7.htm, saved as data/sources/illinois/ilga-constitution-article-vii.html, read Oct 29, 2026): "A home rule unit shall have only the power that the General Assembly may provide by law ... to license for revenue or impose taxes upon or measured by income or earnings or upon occupations." Illinois cities and counties therefore cannot levy a local income or wage tax unless a state law grants that power, and none was found; IL-700-T (2026) and Form IL-W-4 describe Illinois Income Tax withholding only, with no local withholding.
Disability and paid leave: Illinois runs no state disability or paid-family-leave insurance program funded by an employee payroll deduction. Its Paid Leave for All Workers Act (820 ILCS 192) requires employers to let workers earn up to 40 hours of paid leave a year, paid by the employer at the worker's regular hourly rate (Illinois Department of Labor, "Paid Leave for All Workers Act" and its FAQ, labor.illinois.gov/laws-rules/paidleave.html and labor.illinois.gov/faqs/paidleavefaq.html, saved under data/sources/illinois/, read Oct 29, 2026: "employees should receive their regular hourly rate for their paid leave time").
Minimum wage: Illinois Department of Labor, "Minimum Wage Law" (labor.illinois.gov/laws-rules/fls/minimum-wage-law.html, saved as data/sources/illinois/idol-minimum-wage-law.html, read Oct 29, 2026): "Guarantees a minimum wage of $15.00 per hour for workers 18 years of age and older," tipped $9, youth under 18 working under 650 hours a year $13. Minimum Wage Law, 820 ILCS 105/4(a)(1) (saved as data/sources/illinois/ilga-820-ilcs-105-minimum-wage-law.html): "on and after January 1, 2025 ... not less than $15 per hour"; the statute schedules no later increase, so no change is set for 2027. Chicago and Cook County set their own higher local minimums, which this state figure does not cover.
Final paycheck: Illinois Wage Payment and Collection Act, 820 ILCS 115/5 (ilga.gov, saved as data/sources/illinois/ilga-820-ilcs-115-wage-payment-act.html, read Oct 29, 2026): "Every employer shall pay the final compensation of separated employees in full, at the time of separation, if possible, but in no case later than the next regularly scheduled payday for such employee." Illinois Department of Labor, Wage Payment and Collection Act FAQ, question 8 (labor.illinois.gov/faqs/wage-payment-faq.html, saved as data/sources/illinois/idol-wage-payment-faq.html): the rule applies whether the worker quit or was fired.
