As many as 31,000 senior citizens could have saved hundreds of dollars on their property tax bills due August 1, 2018, by applying for exemptions they previously received.

Those homeowners received the Senior Citizen Homestead Exemption for Tax Year 2016 but did not reapply for Tax Year 2017 (due in 2018). Of those seniors, roughly 21,000 previously received the Senior Freeze Exemption but also did not reapply.

Applications for tax exemptions are available from the Cook County Assessor’s Office. If the Assessor’s Office grants the application, it will issue a Certificate of Error.

To check the status of exemptions for a particular property, you may search by address or Property Index Number (PIN).
