Illinois Take-Home Pay Calculator
Calculate your Illinois take-home pay after the state’s 4.95% flat income tax plus federal income tax (2026 brackets) and FICA. Shows monthly and annual net pay and the combined effective tax rate. Enter your gross salary, pay frequency and filing status to see exactly what lands in your Illinois bank account each pay period in 2026, with a line-by-line breakdown of every withholding.
How it works
Illinois levies a flat 4.95% state income tax. The tool first removes the 2026 federal standard deduction ($15,750 single, $31,500 married filing jointly) and applies the progressive 2026 federal brackets slice by slice (10%, 12%, 22%, 24%, 32%, 35%, 37%). It then charges Illinois’s flat 4.95% on your taxable income, and FICA on gross: Social Security at 6.2% up to the $176,100 wage base, plus Medicare at 1.45% on all wages. Net pay is gross minus pre-tax 401(k), federal tax, 4.95% state tax and FICA.
Example
A single filer earning $60,000 in Illinois subtracts the $15,750 standard deduction, leaving $44,250 taxable. Federal tax is 10% of the first $12,400 ($1,240.00) plus 12% of the remaining $31,850 ($3,822.00) = $5,062.00. Illinois adds 4.95% of $44,250 = $2,190.38. FICA is Social Security $3,720.00 + Medicare $870.00. Take-home is $60,000 − $5,062.00 − $2,190.38 − $3,720.00 − $870.00 = $48,157.63 a year, about $4,013.14 per month.
Notes
This is an estimate for guidance only and not tax or financial advice. It uses 2026 federal income-tax brackets and the IRS standard deduction, FICA (Social Security 6.2% to the $176,100 wage base and Medicare 1.45%), and Illinois’s flat 4.95% state income tax. It approximates Illinois taxable income using the federal standard deduction and does not model state-specific exemptions, credits, local taxes, the additional Medicare surtax above $200,000, or other pre-tax benefits. For exact figures consult the IRS, the Illinois Department of Revenue and a tax professional.
