Tax Credits for Workers and Their Families. Dec. 13, 2017. In Detroit, the mayor’s office spearheaded a 2017 EITC Initiative after a study showed that 26,000 eligible households do not claim the credit each year, leaving $80 million on the table. The effort sought to expand awareness and access to the EITC among Detroit residents through billboards, ads on mass transit, emails and public service announcements. The campaign led to approximately 18,150 more Detroit households filing for the credit in 2017, bringing an additional $74 million back into the city.
