Longtime Homeowner Exemption

The Longtime Homeowner Exemption enables property owners to receive an expanded Homeowner Exemption with no maximum exemption amount. Of the 1.5 million residential properties in Cook County, fewer than 2% qualified for the Longtime Occupant Homeowner Exemption last year. This is due to the way the state legislature wrote the provision and the requirements they put in place in order to qualify.

The Cook County Assessor's Office automatically detects which properties qualify based on assessment increases and will mail those that may qualify an application to apply.

Due Date: Friday, August 4, 2023

📌 Reminder: Exemptions appear on your second installment tax bill issued later in the year. To learn more about how the property tax system works, click here.

Eligibility

Owned and occupied your residence from January 1, 2012, to January 1, 2022.
A total household income of $100,000 or less for income tax year 2021.
A property assessment increase that was significant enough to exceed the maximum amounts set by the state legislature.

Please Note: Approximately 11,000 properties in Cook County qualify for this exemption. This is fewer than 2% of homeowners. The Cook County Assessor's Office determines which properties qualify based on assessment increases. These properties will receive application forms in the mail in April 2023.

Documentation Required to Apply

The Cook County Assessor's Office wants all homeowners/occupants to receive the maximum exemption savings to which they are entitled. If we calculate that the Longtime Occupant Homeowner Exemption would provide the most savings for a home, we automatically mail an application. For the 2022 tax year, applications are scheduled to mail by early April of 2023.

If you would like to verify if an application should have been mailed to you, please call the Cook County Assessor's Office at 312-443-7550 and we will double-check your qualifications and apply the exemption(s) that will produce the largest property tax savings for you.

Please note: Properties not eligible to receive this exemption may be eligible to receive the full benefits of the standard Homeowner Exemption.
