So I work construction and worked in 2 different cities last year (Columbus and Ashley). My wife works in another city, Westerville. We filed married filing jointly. We do not live in any of the cities above. What city do we file for local tax? All Ohio cities.
We have no city tax where we live as I confirmed with our city we are outside the city limits. We do live in a township in which their is no income tax collected from the township. Just another wrinkle.
Based on looking at the following website (Ohio Municipal Sites), it appears that you may be required to file a local return with Columbus and Westerville because you or your spouse worked in those locations. These local returns are not supported by TurboTax, but the website link above will take you to each city's website for further information and instructions.
Depending on the employer, you may not be required to file a return if the local taxes were withheld and reported on your W-2s. Take a closer look at each locality's website for more details.
