Illinois applies a flat 4.95% individual income tax. The model uses a personal exemption deduction rather than a standard deduction. Chicago and downstate W-2 employees comparing an Illinois check to Indiana or Wisconsin will see that flat rate on taxable wages after the exemption. The City of Chicago does not add a separate income tax in this engine; we omit local taxes generally. Takehome Cash is a browser estimate for US W-2 employees, not Form IL-1040. Federal brackets are tax year 2026 (Rev. Proc. 2025-32). Social Security is 6.2% up to $184,500. Who it is for includes Chicago and downstate W-2 employees lining up Indiana offers.
This is a W-2 style withholding approximation, not a full Illinois Form resident return. We annualize your pay, subtract pretax 401(k) and section 125 health premiums from federal wages (health premiums also reduce FICA wages), apply the 2026 IRS standard deduction, then apply Illinois’s published rate structure. We do not model local city or county income taxes, itemized deductions, or most credits.
Use the calculator to compare pay frequencies (hourly through annual), pretax 401(k) as a percent or a dollar amount per paycheck, and optional extra federal withholding. Last reviewed against IRS, SSA, and Tax Foundation 2026 publications on October 2, 2026.
Figures are for tax year 2026. If your employer uses a different state withholding method (percentage method vs. wage-bracket tables), your live paycheck can differ by a few dollars even when annual liability is similar.

Illinois paycheck FAQ
Does Illinois have a state income tax on wages?
Yes. Illinois has a flat 4.95% state income tax on taxable wage income in 2026. Local income taxes, if any, are not included in this estimate.
What Illinois income tax rate does this calculator use for 2026?
A single rate of 4.95% after the deductions and exemptions listed in our methodology.
Is this my actual take-home pay?
No. It is an estimate of typical W-2 withholding. It omits local taxes (except a note on New York City), most credits (including the federal Child Tax Credit), unemployment insurance, wage-garnishment, and employer-specific benefits. Use it to plan, not to file.
Does a 401(k) contribution reduce Social Security tax?
Usually no. Traditional 401(k) deferrals reduce federal (and often state) taxable wages, but they remain subject to Social Security and Medicare. Pre-tax health insurance premiums under a cafeteria plan generally reduce FICA wages as well.
