How it works
Property taxes in Madison County are calculated using the assessed value of a property and the combined tax rates adopted by local taxing bodies. These typically include county, municipal, school district, and other special district levies. The calculator applies a single combined rate to the assessed value to estimate annual property tax.
Examples
In Illinois, equalized assessed value (EAV) is multiplied by the aggregate tax rate for the parcel’s taxing district. Entering both values produces an estimated annual tax amount.
Limitations and important notes
This calculator provides an estimate only. Madison County property tax rates vary by taxing district, voter-approved levies, and parcel location. Exemptions, reassessments, and special assessments are not fully reflected, and the actual tax bill may differ from the estimate.
