Residents in Rittman will head to the polls on May 2nd to vote on the future of the city’s income tax.  The voting comes just months after the city acknowledged that an administrative error led to residents getting overtaxed by $7 million over the course of 15 years.  If approved, the income tax issue would add half a percent to the city’s current base rate of 1%.  Rittman officials estimate the 1.5% income tax would generate roughly $750,000 annually for the city.  If the income tax increase fails next month, the city has already told residents that certain services could be cut.
