Property tax exemptions are savings that contribute to lowering a homeowner’s property tax bill. The most common is the Homeowner Exemption, which saves a Cook County property owner an average of approximately $950 dollars each year. Read about each exemption below.
To determine which exemptions are currently being applied to a residence, homeowners can review their Property Details, and then review the Exemption History and Status section to determine which exemptions they received.
New homeowners and returning applicants can apply online.
If a homeowner believes they are entitled to exemptions in previous tax years, a Certificate of Error application can be filed to redeem past savings. Click on the individual exemption below to learn how to file.
The exemption application for tax year 2024 is now available. Apply by Monday, April 21, 2025 for savings on your Second Installment Property Tax Bill.
