Because Treasury has started issuing the expanded Michigan EITC supplemental check payments for tax year 2022, it is no longer necessary to view or manually update your address. If you moved between last year and now, please be sure your new address is on your 2023 individual income tax return filing.
3. What form should I use to amend my return?
If you lived inside the City of Detroit for the entire tax year in question (January 1st through December 31st), you should file as a resident of the City of Detroit. File your amended return using the City of Detroit Resident Income Tax Return (Form 5118).
If you lived outside the City of Detroit for the entire tax year in question (January 1st through December 31st), you should file as a nonresident of the City of Detroit. File your amended return using the City of Detroit Nonresident IncomeTax Return (Form 5119).
If you lived in the City of Detroit part of the year, but less than a full year (anytime between January 1st and December 31st), you should file as a part-year resident. File your amended return using the City of Detroit Part-Year Resident Income Tax Return (Form 5120).
If you initially filed using the incorrect form, file using the form which matches your residency in the City of Detroit for the tax year in question. If you are changing forms, you may be required to provide documentation to support your residency.
Note: Include form 5121 City of Detroit Withholding Tax Schedule if you are amending because of a corrected W-2 or additional W-2 forms received after you filed your original return. If you need to allocate your wages, or change an allocation, you must submit form 5121 and complete part 3.
Please see supporting documents which may be required for amending your return.
