Property Tax Bills Across Clinton County, Illinois
Property tax bills in Clinton County are based on the assessed value of a home, not its market price alone. Local taxing authorities apply their tax rates to that assessed value, and the final bill reflects the combination of county, municipal, school, and other local levies. Homeowners with similar homes can still see different bills if their assessments or taxing districts differ.
With a median home price of $152,625, property taxes can vary widely across the county. The median tax bill reaches $4,558.00 in Aviston, while Huey has a much lower median bill of $1,024.00. Across the county, the 25th percentile tax bill is $1,654, the 75th percentile is $4,569, and the 90th percentile is $6,227.
These differences matter because property taxes directly affect monthly housing costs and long-term affordability. When assessments rise or local tax rates increase, homeowners may see their bills climb even if they have not made changes to the property.
