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 to qualify.

The Cook County Assessor's Office automatically detects which properties qualify based on assessment increases and will mail an application to those that may qualify in April 2024. 

Due Date: The filing period for tax year 2023 will open in early spring. 

📌 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
