How Illinois paycheck taxes work
Illinois keeps its income tax about as simple as a state this size gets: a single flat rate of 4.95% applies to every filer, regardless of income level or filing status. The only thing that reduces what's taxed is a personal exemption allowance of $2,925 per exemption for 2026 (doubled to $5,850 for married couples filing jointly); Illinois doesn't use a lump-sum standard deduction the way most states do, it's built entirely around this per-person exemption instead. This calculator applies the base personal exemption but doesn't add Illinois' extra $1,000-per-dependent exemption, since it doesn't collect a dependent count, so real take-home pay for someone with dependents will run a bit higher than this estimate. Illinois law doesn't let cities or counties levy their own income tax, so even Chicago residents pay only the flat state rate on top of federal tax and FICA: no local income-tax layer to account for, and no state disability insurance or paid-family-leave payroll deduction either.
Federal income tax is calculated using the 2026 IRS tax brackets after subtracting your standard deduction, based on your filing status. FICA is a flat 6.2% Social Security tax (up to the annual wage base) plus 1.45% Medicare tax, with an additional 0.9% Medicare tax on income above $200,000 (single) or $250,000 (married filing jointly).
