Colorado vs. Illinois Property Taxes

Intro
Both Colorado and Illinois levy property taxes that fund local services such as schools, police, and road maintenance. According to the U.S. Census Bureau's 2023 American Community Survey (5‑year estimates), Colorado’s effective property‑tax rate is less than one‑quarter of Illinois’s rate. The disparity in rates leads to substantially different annual tax bills for comparable home values.
