Frequently Asked Questions
What is the Illinois income tax rate for 2026?
Illinois taxes wage income at a flat 4.95% in 2026. Everyone pays the same marginal rate regardless of how much they earn.
How accurate is this Illinois paycheck estimate?
It is an annualized estimate: your gross wages minus the 2026 standard deduction (and any state exemptions/credits shown), run through 2026 marginal brackets. It does not include pre-tax deductions like 401(k) contributions or health insurance premiums, itemized deductions, or local income taxes. Your employer's actual per-paycheck withholding can differ.
Are local or city income taxes included?
No. Several states — including Maryland, Ohio, Pennsylvania, New York, Michigan, Missouri, Indiana, Kentucky, and Oregon — have county, city, or school-district income taxes that this calculator does not model. If you work in one of those places, your real take-home pay will be lower than shown.

Estimate only — not tax advice. This calculator annualizes your gross wages, subtracts the 2026 standard deduction (and state personal exemptions/credits where shown), and applies 2026 marginal brackets. It does not model pre-tax deductions (401(k), health insurance), itemized deductions, credits you may qualify for, phaseouts, or local/city/county income taxes. Your employer's per-paycheck withholding may differ. Consult a tax professional for your situation.
