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.
To verify or find out if
you live in a school district* or city with an income tax enter your address at:

You do not get a credit, on a School District Income Tax (SDIT) return, for tax withheld for City Income Tax (CIT). CIT & SDIT are two different taxes.
