Take-home pay in Illinois, 2026

Illinois has a flat 4.95% state income tax. Combined with 2026 federal brackets and FICA, here is what that means for a single filer taking the standard deduction.

Federal income tax

The 2026 brackets run from 10% to 37%, applied after the standard deduction ($16,100 single, $32,200 married filing jointly). Only income inside each bracket is taxed at that bracket's rate.

FICA

Social Security takes 6.2% of wages up to $184,500, and Medicare takes 1.45% of everything, plus 0.9% more above $200,000 ($250,000 married). Pre-tax 401(k) contributions do not reduce FICA.

Paychecks in Illinois, the honest answers

  • Illinois has a flat 4.95% state income tax. On top of that, federal income tax (10% to 37% after the standard deduction) and FICA (7.65% for most earners) apply everywhere. The calculator above shows the full breakdown for your exact salary.

  • Illinois has a flat 4.95% state income tax. Use the compare feature above to see the same salary side by side with another state; the difference is often smaller, or larger, than people assume.

  • Gross salary minus federal income tax (2026 brackets after the standard deduction), minus Social Security (6.2% up to $184,500) and Medicare (1.45%, plus 0.9% at high incomes), minus your state's income tax. What remains, divided by your pay periods, is each check.

  • Real payroll also withholds health and other benefit premiums, applies your W-4 elections, and may include local taxes, none of which a general calculator can know. Treat this as a close planning estimate, not a payroll stub.

  • No. It is a transparent estimate built from published 2026 IRS and Tax Foundation figures, and the assumptions are stated right under the result. For decisions with real money at stake, confirm with a tax professional.

  • No. The whole calculation runs in your browser. Nothing you enter is sent to a server or stored.
