Property Tax Bills Across Downers Grove, Dupage County, Illinois
Property tax bills in Downers Grove are based on the assessed value of a home, not its market price alone. Local taxing bodies set tax rates, and the bill is calculated by applying those rates to the assessed value after exemptions and other adjustments are considered. Because the tax bill depends on both valuation and local levies, two homes with similar market values can still receive different bills.
For homeowners, this means property taxes can change when assessed values rise or when local taxing needs increase. In Downers Grove, the median home price is $390,930, while the median property tax bill is $7,211 in ZIP code 60515 and $7,172 in ZIP code 60516. That is well above the national median property tax bill of $2,400 and the national median property tax rate of 1.02%.
