Appendix A : A Closer Look at Your Property Taxes
All About Your Property Tax Bill​
​
Your property tax bill includes taxes for many different government entities. Illinois has more units of government than any other state so it is not unusual to pay a dozen or more government entities through your property tax bill. Each government entity prepares its own budget and submits it to the Cook County Assessor’s office. This office then sends out the property tax bill which is based on the budget and on your home’s assessed value.
Calculating Your Property Tax Bills
The Cook County Assessor’s office does not set tax rates or levies or decide the dollar amount of your tax bill. The main job of the Cook County Assessor is to determine the Assessed Fair Market Value (MV) of your property.

The County Clerk is actually the person responsible for “backing into” the tax rate. A tax rate is set by taking the budget of all of the taxing entities such as a school district or a fire protection district and spreading that cost out over the EAV throughout the district. Each bill in Glenview will be different as it is based upon where you live.​
Appealing Your Property Taxes
If you believe your taxes are unfair, you may file an appeal. You’re not really appealing your property taxes but rather the assessed value of your home. You need to follow the instructions found on the Cook County Assessor’s website and present a solid argument as to why your home is assessed too high. Common arguments include:
-
Lack of uniformity (your home is not in line with the assessed value of other homes in the area)
-
Overvaluation (the assessed value is not in line with the market value of your home based on what similar homes have recently sold for)
-
Incorrect information (the county is incorrect in what they think you own – e.g. the house is much smaller than they think, damaged by fire, etc.
