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.
You may end up owing your resident city nothing,
but you are still required to file a return.
