Welcome to the Cook County Board of Review online appeal form.

File An Appeal

In order to better serve all property owners, we are now accepting pre-registration requests for all townships. Pre-registration allows taxpayers to be notified by the Board of Review of the opening and closing filing periods for their respective townships.

The Pre-file period (Non-Attorneys) will begin Wednesday, June 25, 2025. The pre-file period allows all filers to submit their appeal before each township officially opens. Please be advised that the Pre-file period will end once the respective township is open. Please refer to this page for a list of dates and deadlines after the filing period has been determined for your respective township. All appeals must be submitted before the township closing dates listed on this form.
