For properties owned by entities such as charitable organizations, hospitals, religious institutions, schools, and government agencies.

Every year, entities that own properties deemed exempt from taxation must file an Annual Exempt Affidavit. These properties are deemed exempt from taxation by the Illinois Department of Revenue, which has sole authority to grant or deny applications for exemption. Examples of such properties that may qualify for exemption are charitable organizations, government agencies (federal, state, and local), hospitals, religious institutions, schools, and others specifically identified in Article 15 of the Property Tax Code. 

The Assessor’s Office now has a NEW online application for submitting the affidavit for all properties exempt through the 2022 assessment year. Affidavits will be accepted as they come in; however, please return them as soon as possible so they may be processed. 

Instructions on how to file: 

Properties deemed exempt will receive either a letter by mail or email from the Assessor's Office with a specific "Agency Control Number" and password to access information specific to your property. 

1. Read through the User Guide before beginning the online application. Start on page 10 for specific filing information pertaining to the Annual Exempt Affidavit. 

2. Begin the online application by clicking the link below. 

3. Choose the option that reads, "Annual Exempt Affidavit or Change Filing (2023)."
