Illinois paycheck FAQs

How do IL-W-4 allowances reduce my Illinois withholding?

Each Line 1 allowance (yourself, and one if you're not claimed as a dependent elsewhere) shelters $2,925 of annual wages from the 4.95% tax; each Line 2 allowance (claimed if you or your spouse is 65+ or blind) shelters $1,000. The total is divided by your number of pay periods and subtracted from each paycheck before the tax is applied.

Are there any city or county income taxes in Illinois?

No. Unlike neighboring states, Illinois has no local income taxes — Chicago and every other municipality rely on sales and property taxes instead. The 4.95% state rate is the only income tax withheld anywhere in Illinois.

Is the Illinois flat tax the same for everyone?

Yes — 4.95% applies to all wage income regardless of how much you earn or your filing status; only your allowances change your withholding, not your rate.
