Per the Cook County Assessor’s Office, “The 2021 assessment and appeal schedule coincides with the implementation of iasWorld, a new integrated property tax system. This upgrade moves us off an aging mainframe system onto a state-of-the-art platform that allows property owners to more easily access and update property data. Therefore, assessment mailing dates and appeal dates are subject to change.”
