Are There Property Tax Exemptions in Cook County?

Homeowners in Cook County may qualify for several property tax exemptions that can lower their tax bill. These are offered through the Cook County Treasurer’s Office, depending on your location. Common exemptions include:

Homeowner exemption: For homeowners occupying the property as their principal residence on January 1 of the tax year. This exemption reduces the equalized assessed value (EAV) by $10,000.
Over-65 exemption: Must be the owner-occupant of the residence and aged 65 or older in the year prior to the tax year. This is the same reduction as the homeowner exemption.
Disabled individual exemption: For disabled individuals who own and occupy their primary residence, there is an annual reduction of $2,000 in EAV.
Veteran with disabilities exemption: For qualified veterans with service-connected disability and property under $250,000 EAV.

If you’re buying a home in Cook County, note that property tax exemptions do not automatically transfer from the previous owner. After the home changes hands, you’ll need to reapply based on your own eligibility.
