Property owners in Cook County may have the opportunity to take advantage of a variety of property tax exemptions, resulting in savings on their property tax bill. Savings from these exemptions appear as deductions on the second installment property tax bills mailed in the summer.

​

Residents applying for the Homeowner Exemption, the Senior Citizen Exemption, the Senior Freeze Exemption, and the Home Improvement Exemption must apply annually to receive the deduction on their property tax bills.

​

The Cook County Assessor's Office has streamlined the application process by moving applications online into a single form. Homeowners can check the Cook County Portal website and review their Exemption History and Status to determine which expressions they received last year and if they will auto-renew thisyear.
