State Overview
Property Taxes in Illinois
Illinois Taxes High Above National Norm
Illinois homeowners pay an average effective property tax rate of 1.831%, nearly 78% higher than the national median of 1.03%. This ranks Illinois in the top 10 highest-tax states in the nation, making property taxes a significant cost factor for residents across the state.
Massive Tax Variation Across 102 Counties
Illinois exhibits extreme county-to-county variation: Pulaski County's effective rate of 0.825% stands nearly one-third lower than Lake County's 2.677%, a difference of 1.852 percentage points. This wide spread reflects dramatic disparities in local tax bases, services, and assessment practices that directly impact where families choose to live.
Typical Illinois Homeowner Pays $2,782 Annually
The median statewide property tax bill stands at $2,782 on a median home value of $146,132—a steep burden compared to the national median home value of $281,900. Illinois homeowners pay roughly the national median in absolute dollars while living in homes worth significantly less, revealing a heavier per-dollar tax burden.
Wealthy Suburbs and Collar Counties Lead Taxes
Lake, DuPage, and Kendall counties—affluent Chicago-area suburbs—top the state with median bills of $8,743, $7,833, and $7,556 respectively, driven by high property valuations and strong local services. By contrast, rural southern counties like Pulaski, Alexander, and Hardin pay under $1,100 annually, creating a stark divide between thriving metros and struggling downstate regions.
Illinois: High-Tax State With Sharp Geographic Divides
Illinois ranks decisively high-tax nationally, with rates 78% above the U.S. median and significant variation driven by wealth concentration in Chicago's suburbs. Working- and middle-class homeowners in Lake County or DuPage County bear the heaviest burdens, while those seeking lower taxes gravitate to rural downstate counties—a pattern that reinforces regional economic inequality.
