On Thursday, ABC7 is partnering with the Cook County Treasurer's Office for the Our Homes Matter Phone Bank.
Owners of residential properties may be eligible for six types of exemptions: homeowners, senior citizen, senior freeze, returning veteran, disabled person and disabled veteran.
Past phone banks have helped return $28 million in the form of tax refunds and exemptions.
The phone lines are open at 312-603-5105 from 11 a.m. until 4:30 p.m.
Before you call, you need to have your address and property index number.
