Assessment Calendar and Deadlines

The 2021 assessment and appeal schedule has not been finalized. We will publish information on this page later this month. Our phone lines remain open to the public during normal business hours and assistance is available via our website and social media channels.

It's 2021, and our Office has been hard at work accomplishing the following:

Preparing for Chicago's 2021 reassessment.

Automatically renewing exemptions throughout Cook County.

  • Hundreds of thousands of seniors, Senior Freeze recipients, persons with disabilities, and veterans with disabilities were sent mail about their exemptions being automatically renewed.  Read more >> 
  • Homeowners who need to apply for exemptions can apply online.

Upgrading technology for better service and transparency.

  • In March 2020, we're launching the first phase of the County’s 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.

 

The 2021 assessment and appeal schedule is coming soon.
