The Cook County Treasurer said homeowners in the county may be owed money, and a simple check-in online is all they need to do. Maria Pappas said during this hard time, there are millions of dollars which could be refunded to county taxpayers, WLS/Channel 7 reports.

There are two pots of money to tap into: Millions in overpaid property taxes, or millions in possible unclaimed exemptions.

Pappas urged homeowners to visit cookcountytreasurer.com.

"You go there, you put in your address and it tells you if you have overpaid going back 20 years," Pappas said.
