Get your taxes done using TurboTax

Although most Michigan cities require the mailing of separate tax returns, I believe Detroit returns are usually included with the state return.  So, TurboTax probably did file city returns. 

 

You may need a tax professional.  But, you may only need to contact the city to straighten this out.   It sounds like they think you are subject to city tax because you have been filing a city return every year. Your employer probably mistakenly withheld city tax
