No. Unlike New York City or Detroit, Chicago does not tax wages. Workers pay federal tax, the Illinois flat 4.95% state tax and FICA only, the city's revenue comes mainly from property and sales taxes instead.
Illinois has a constitutionally mandated flat rate of 4.95% on all taxable income, with a personal exemption allowance ($2,925 for tax year 2026) subtracted first. Changing the flat rate to a graduated one requires a constitutional amendment, which voters rejected in 2020.
Actual withholding reflects your IL-W-4 elections, filing status (this estimate uses single), pre-tax benefits like health insurance and any additional withholding you requested. Expect differences of a few percent from your payslip.
Illinois taxes income at a constitutionally flat 4.95%, there are no brackets to manage, and the graduated-tax amendment that would have changed this was rejected by voters in 2020. On top of the flat rate, tax year 2026 gives each filer a $2,925 personal exemption (up from $2,850 in 2025 — the figure is inflation-adjusted annually by the Illinois Department of Revenue). Chicago itself levies no city income tax, so a Chicago payslip differs from a Peoria payslip only in local sales taxes paid when spending, not when earning.
The calculator uses single filing status, the 2026 federal standard deduction ($16,100) and 2026 brackets, Social Security at 6.2% up to the $184,500 wage base, and Medicare at 1.45%. Your real withholding adds whatever your W-4 and IL-W-4 request, pre-tax insurance premiums, and possibly the 0.9% additional Medicare tax above $200,000. Expect a few percent of drift, that is normal; if the gap is larger, the usual culprit is a pre-tax deduction this estimate does not know about.
