About Us

The Cook County Property Tax Portal is a collaborative effort that combines property tax information from the Cook County Assessor’s Office, the Board of Review, the Clerk’s Office, the Recorder of Deeds, and the Treasurer’s Office into one unified site. This site will allow residents to have online access to comprehensive information about their properties such as appeal or exemption opportunities or liens, saving time and promoting efficiency for taxpayers.
On this website, a property owner will enter a PIN or address and get five years of history, in linear form and on a single screen, without having to visit various websites to determine what is owed, paid and what refunds might be available. Owners can also get information to begin the process of appealing their property taxes or apply for a missed exemption.
This portal compiles information that will hopefully be more sensitive to your needs, more convenient for use and more efficient for residents of Cook County.
