Composite rate, as a percent of assessed value, from the published 2024 rates. Illinois taxes a home at a third of its market value: the bill is the assessed value times the composite rate, which adds up every taxing district on the property (county, township, municipality, school, park, library and others). The effective rate on market value is about a third of the composite rate. The State's equalization factor for Grundy County is 1; it adjusts assessed values to a common level.
