How the Illinois salary calculator works
This Illinois paycheck calculator starts from your gross pay, subtracts pre-tax deductions such as 401(k) and HSA contributions, then applies the 2025 federal standard deduction and marginal brackets. Social Security is withheld at 6.2% up to the annual wage base and Medicare at 1.45% (plus 0.9% on wages above $200,000). Finally, Illinois state income tax is applied to your state taxable income.
Illinois state income tax
Illinois has a constitutionally flat 4.95% income tax with a personal exemption instead of a standard deduction.
Because the rate is flat at 4.95%, every additional dollar you earn in Illinois is taxed at the same state rate — only your federal bracket changes as income rises.
