Illinois Tax Overview — What Workers Need to Know

Illinois imposes a flat 4.95% income tax rate on all earned income, regardless of how much you make. Unlike progressive-rate states like California or New York, every dollar of Illinois taxable income — from the first dollar to the millionth — is taxed at exactly the same 4.95% rate. This simplicity makes paycheck calculations straightforward: on a $60,000 salary, Illinois state income tax is approximately $2,970 (the standard exemption reduces taxable income slightly). In 2020, Illinois voters rejected the "Fair Tax Amendment" (also called the graduated rate amendment) by a 53%–47% margin, preserving the flat tax structure. Illinois also levies a 6.25% state sales tax (with local additions reaching 10.25% in Chicago), and property taxes that are among the highest in the nation — averaging 2.07% statewide, the second-highest rate in the US behind New Jersey. Cook County (Chicago) property taxes are especially notorious, with effective rates often exceeding 2.5%. The combination of a flat income tax, extremely high property taxes, and elevated sales taxes in urban areas has contributed to significant outmigration: Illinois has lost population every year since 2014, with many residents relocating to Indiana (3.05% flat tax, lower property taxes), Tennessee (0% income tax), or Florida. Despite these challenges, Illinois has the 5th-largest state economy, driven by Chicago's role as a major financial, transportation, and professional services hub, with a median household income of $78,433.

Common Questions

Frequently Asked Questions.

Wage conversion, tax withholding, and paycheck calculation answers.

Does Illinois have state income tax on paycheck wages?
Illinois levies state income tax on earned wages (4.95% Flat Income Tax). PayCalcAI calculates your precise state tax withholding based on annual income.
How do I calculate net paycheck in Illinois?

Is Illinois income tax flat or progressive?
Illinois has a flat income tax rate of 4.95% on all taxable income. In November 2020, Illinois voters rejected the "Fair Tax Amendment" that would have replaced the flat rate with a graduated (progressive) system. Under the current system, a worker earning $40,000 and a worker earning $400,000 both pay exactly 4.95% on their state taxable income.
Why are Illinois property taxes so high?
Illinois property taxes average 2.07% — the 2nd highest in the nation — primarily because the state relies heavily on local property taxes to fund public schools, municipal services, and pensions. Illinois has over 6,900 local taxing districts (the most of any state), each with the authority to levy property taxes. Underfunded public pension obligations also contribute to the high rates.
How much state tax does a $60,000 salary pay in Illinois?
A single filer earning $60,000 in Illinois pays approximately $2,970 in state income tax. The calculation is straightforward due to the flat rate: ($60,000 - $2,625 personal exemption) × 4.95% = $2,840. The exact amount varies slightly based on allowable deductions and withholding adjustments.
Does Illinois tax retirement income?
No. Illinois does not tax most retirement income. Social Security benefits, pension payments, 401(k) and IRA withdrawals, and other qualified retirement income are exempt from Illinois state income tax. This makes Illinois surprisingly retirement-friendly despite its high overall tax burden on wage earners.
How does Illinois compare to Indiana for tax burden?
Indiana's flat income tax rate is 3.05% (vs Illinois at 4.95%), and Indiana's average property tax rate is 0.83% (vs Illinois at 2.07%). A worker earning $75,000 with a $300,000 home would pay approximately $3,720 less in combined state income + property taxes by living in Indiana rather than Illinois — a significant factor driving cross-border migration.
