Estimate take-home pay on a paycheck in Illinois after federal and state taxes.
A take-home pay estimate in Illinois: gross minus estimated federal income tax, FICA (Social Security + Medicare), and an approximate state component. Actual withholding depends on W-4 choices and city taxes.
Net
Net = gross − federal − FICA − state
Approximate estimate — not official payroll.
Your W-4, pre-tax benefits (health, 401k) and local taxes change withholding.
Rates are approximate reference values. Local rates, exemptions and rules can differ, so treat the output as a planning figure only.
