Filing Requirements FAQs
1. Who should file a City of Detroit Individual tax return?

File a return if you owe tax, are due a refund or your Adjusted Gross Income (AGI) exceeds your exemption allowance. You should also file a City return if you file a federal return, even if you do not owe City Tax. This will eliminate unnecessary correspondence from Treasury.

Note: The filing due date is April 18, 2016 for the 2015 tax return. Choose to e-file instead of filing a paper return and get your refund fast!

2. If you cannot e-file your return and need to file a paper return, follow the information below to determine which form to use:
  1. Form 5118 – City Resident Income Tax Return – Complete this form if you were a resident of the City of Detroit for the entire calendar year.
  2. Form 5119 – City Nonresident Income Tax Return – Complete this form if you were not a resident of the City of Detroit for any part of the calendar year, but had taxable income earned in the City of Detroit.
  3. Form 5120 – Part Year Income Tax Return – Complete this form if you were a resident of the City of Detroit for any portion of the calendar year, but were not a resident for the entire year.

See the E-File Section for additional information regarding e-filing your City of Detroit return

3. What should I do if I received another W-2, or have discovered an error on my return after I filed?

If there is a change to your federal adjusted gross income or the allowable exemptions, City Tax law requires the filing of an amended return.

Note for e-filed returns: If you made an error on an electronically filed return for the tax year 2015 or later, you must file a paper amended income tax return. An amended return cannot be e-filed.

File the same form you originally filed with the amended box checked in the upper right corner and submit by mail. Amended returns received using the incorrect form or missing pages will not be processed.

You must provide an explanation of the changes on page 2 of the amended return under Part 6. Failure to include an explanation may result in a denial of the return.

Include an amended Schedule W form if you are amending because of a corrected W-2 or additional W-2 forms received after you filed your original return.
