Pre-filing Now Open for 2017 Session

The Cook County Board of Review is pleased to announce pre-filing for the 2017 Assessment Appeal Session begins July 5, 2017. Pre-filing is available online for ALL townships. You may pre-file by visiting the Board of Review website. Once you have submitted your appeal, you will receive an email confirmation with a complaint number.

If you filed online last year and created an account, simply login, include any new evidence you would like to have considered, and submit. Your property information is stored through your account. Please Note: When pre-filing an appeal based on lack of uniformity, only turn in evidence AFTER the Assessor certifies your township. For a schedule of the Cook County Assessor’s Dates and Deadlines please click here.
