What your salary leaves after taxes in Illinois (2026)
Illinois levies a constitutionally mandated flat income tax of 4.95%. The state subtracts a modest personal exemption of $2,850 (single) before applying the rate, but there is no standard deduction. Illinois also charges no local income tax, so the 4.95% is the full state-level bite. Here is how three salary levels shake out.
| Gross salary | Federal tax | FICA | IL 4.95% | Take-home | Eff. rate |
|---|---|---|---|---|---|
| $50,000 | $3,820 | $3,825 | $2,334 | $40,021 | 20.0% |
| $75,000 | $7,670 | $5,738 | $3,571 | $58,021 | 22.6% |
| $100,000 | $13,170 | $7,650 | $4,809 | $74,371 | 25.6% |
Single filer, 2026 federal brackets, $2,850 IL personal exemption. No local income tax in Illinois.
The property-tax offset most people overlook
Illinois has no local income tax, but it makes up the difference through property taxes averaging about 2.07% of assessed value — roughly double the national average. A homeowner with a $300,000 property pays around $6,200 per year in property taxes. This does not hit your paycheck directly, but it is a major factor when comparing total cost of living against states like Indiana (property taxes about 0.84%) or Michigan (about 1.38%).

Illinois versus neighboring flat-tax states
At 4.95%, Illinois takes the most in state income tax of any flat-tax state in the Midwest. On $100,000, the gap is clear: you keep $74,371 in Illinois versus $76,230 in Indiana, $75,176 in Michigan, and $77,082 in no-income-tax states across the border in Wisconsin (which uses brackets but has lower effective rates below $100K). The constitutional flat-rate requirement means Illinois cannot shift to progressive brackets without an amendment — a proposal that was rejected by voters in 2020.
