I applied for an appeal already, when and how do I receive the results?

Appeal result letters for the first reassessed townships have been mailed. More result letters will follow as appeals are processed. Please note that no result letters will be available for in-person pickup at the Cook County Assessor’s Office. They will be mailed to either the property owner or the property tax practitioner who filed the appeal on behalf of the property owner.

In addition, property owners who did not receive a COVID-19 adjustment in their reassessment will receive an additional letter notifying them of any COVID-19 adjustments made to the assessed value of their property. This is separate from the appeal result letter. Both the results of appeals and COVID-19 adjustments will be made available on our website.
