Property Tax Bills Across Zion, Lake County, Illinois
How are property tax bills calculated in Zion, Lake County, Illinois?
Property tax bills in Zion are based on the assessed value of a home, not its market price alone. Local taxing authorities apply tax rates to that assessed value, and the final bill reflects the combined cost of schools, county services, municipal services, and other local levies. Because these rates and assessments can change, two homes with similar market values may still receive different bills.
What factors affect a homeowner’s bill?
A home’s assessed value, the local tax rate, and any exemptions all play a role in the amount owed. In Zion, the median home price is $185,748, while property tax bills are much higher than the national median property tax bill of $2,400. The 25th percentile tax bill is $4,890, the 75th percentile is $8,018, and the 90th percentile is $9,652.
