Cook County commissioners are set on Thursday to green-light a tax incentive for a celebrated new banking call center in Chicago’s Chatham neighborhood that was once the husk of a Target store that closed at the busy South Side intersection. The tax break — designed to give a boost to abandoned commercial properties — is set to save the property owner millions in potential real estate taxes as the call center ramps up during the next decade.

The class 7b tax incentive (22-2222) is one of seven local property tax breaks and dozens of other items set for final approval during the Board of Commissioners’ monthly meeting at 10 a.m. Thursday.
