You normally only have to
file a return in the city you live in. It is not necessary to file one in the
city you work in, if different. Your employer will remit withholding to the
city you work in, but you do not file a return unless you're claiming a refund or
your employer didn't withhold enough ( both highly unusual). The city you live
in will allow a credit or partial credit for the withheld tax you paid to the
work location city.
There are no county income taxes, in Ohio. But there is School District Income tax (SDIT). What you think is Stark county tax may be SDIT. Ask your employer. You only may SDIT to your residence SD. Not tax should be withheld for work location SD.

you live in a school district or city with an income tax enter your address at:
