Illinois has a flat 4.95% income tax. Before applying it, your employer subtracts $2,925 for each allowance on your IL-W-4 (2026 amount). There is no Illinois disability or family leave payroll deduction, and Illinois cities, including Chicago, do not withhold local income tax. On top of state deductions, every worker pays federal income tax (based on your W-4), Social Security at 6.2%, and Medicare at 1.45%. For a single worker earning $25 an hour full time, total deductions come to about 20% of gross pay.
Illinois' minimum wage is $15.00 per hour in 2026, unchanged since it reached that level on January 1, 2025. Chicago and Cook County set higher local minimums, and tipped workers can be paid 60% of the minimum wage ($9.00) if tips make up the difference.
Illinois requires 1.5× pay for hours over 40 in a workweek, matching the federal rule. Illinois has no daily overtime requirement. Enter your weekly overtime hours in the calculator to include them. Under the federal "no tax on overtime" rule for 2025–2028, you may be able to deduct up to $12,500 of the extra half of your overtime pay ($25,000 if married filing jointly) on your federal return. That deduction is claimed when you file, so it does not lower the withholding shown here unless you adjust your W-4.
No. Chicago does not withhold a city income tax from wages, so your Illinois paycheck is the same whether you work in Chicago or elsewhere in the state. The flat 4.95% state rate applies everywhere.
Each Line 1 allowance shields $2,925 of annual wages from the 4.95% tax, which is about $145 less tax withheld per year — roughly $5.57 per biweekly paycheck. Claiming fewer allowances than you are entitled to means a larger refund. Claiming more means a smaller paycheck deduction now but possibly a balance due when you file.
It uses the official 2026 withholding formulas, so for a standard W-4 and IL-W-4 allowances with no other deductions it should be within a few dollars of your actual paycheck. Your real check will be lower if you have pre-tax deductions like 401(k) contributions or health insurance premiums (those also reduce your income tax), or extra withholding on your W-4.
