Property Tax Bills Across Charleston, Coles County, Illinois
Property tax bills in Charleston are based on the assessed value of a home and the local tax rate set by taxing authorities. The assessed value reflects a portion of the home’s market value, and that figure is multiplied by the applicable tax rate to determine the bill. For homeowners, this means that changes in market conditions, home improvements, or reassessments can affect what they owe each year.
With a median home price of $99,892, property taxes can still vary widely across the city. The tax bill is not the same for every homeowner because it depends on the home’s assessed value and where it is located within the tax district. In Charleston, the median tax bill is $1,810 in ZIP code 61920, which is below the national median property tax bill of $2,400.
