Illinois levies a flat 4.95% state income tax on wages — no separate state payroll tax layered on top for most employees. Illinois is often discussed alongside relatively high property taxes statewide, which affects housing budgets more than your paystub line items. Together with federal withholding and FICA, a typical worker sees state tax as a steady slice of gross pay; use the calculator below for your filing status and pre-tax deductions.
Illinois local wage taxes are not modeled. Figures use the app’s flat 4.95% IL rate and simplified federal withholding.

Chicago residents do not pay a separate city income tax on wages like some municipalities elsewhere, but Cook County and the city layer other taxes (e.g. sales, fees) that do not appear on a standard state wage withholding stub. Nationally, Illinois is frequently cited for elevated property tax burdens — relevant for rent-vs-own decisions, separate from the income and FICA lines above.
Illinois uses a flat state income tax rate of 4.95% on taxable wages in this calculator’s 2026 model. There is no separate graduated state bracket system like California or New York. Your actual withholding can still vary with allowances, bonuses, and local add-ons not modeled here.
Employers generally withhold federal income tax (based on your W-4 and IRS tables), Illinois state income tax at the flat rate, Social Security (6.2% up to the wage base), and Medicare (1.45%, plus 0.9% additional Medicare above IRS thresholds). This tool estimates annual amounts using federal standard deduction and flat IL tax on gross after pre-tax 401(k)/health inputs only.
Illinois does not impose a statewide local income tax on wages in the same way Pennsylvania’s local earned income tax works. Chicago and some other jurisdictions have separate sales, utility, or business taxes, but employee wage withholding is dominated by state flat tax plus federal and FICA. Property taxes in Illinois are relatively high compared with many states — that affects housing cost, not this paycheck estimate.
Versus Wisconsin, Iowa, Missouri, Indiana, and Kentucky, take-home pay differs mainly by each state’s income tax structure. Indiana and Michigan use flat rates; Wisconsin is progressive. At similar gross pay, Illinois’s 4.95% flat rate often sits in the middle — higher than no-tax neighbors you do not border, but compare your exact offer in the calculator by switching states.
Typical employee deductions include federal income tax, Illinois state income tax (4.95% in the model), Social Security, Medicare, and any pre-tax items you elect (401(k), health insurance, FSA). Post-tax deductions like union dues or garnishments are not included in this tool.
Increase pre-tax retirement contributions only shifts tax timing but can lower taxable income. Adjusting your Form W-4 changes federal withholding; avoid over-withholding unless you prefer a large refund. Compare medical plan costs, use HSAs/FSAs where appropriate, and verify you are not duplicating Illinois withholding with outdated W-4 settings.
