Filing a Detroit Fiduciary Income Tax Annual Return

Every partnership with business activity in the City of Detroit, whether or not an office or place of business was maintained in the city, is required to file an annual return using the City of Detroit Income Tax Partnership Return (Form 5458).

Syndicates, joint ventures, pools and like organizations along with LLCs electing to be taxed as partnerships at the federal level will also use Form 5458.

Report the 179 deduction on line 23 of Schedule C on the City of Detroit Income Tax Partnership Return (Form 5458) and include supporting documentation with your return.

Please do not staple return paperwork together before placing into an envelope. If necessary, attach paperwork with paper clips or binder clips before mailing.

If the partnership elects to pay tax for the partners by making estimated income tax payments then the partners may be required to make payments as individuals, if they have other income attributable to Detroit.

The annual City of Detroit Income Tax Partnership Return (Form 5458) filed by the partnership should be accompanied by a statement showing the names, addresses and social security numbers of the partners on whose behalf the payments are being made.

The partnership may pay the tax for partners only if it pays for all partners subject to the tax.  Partnerships electing to pay the tax on behalf of the partners assume the status of taxpayer to the following extent: 

• Timely payment(s) must be made 
• If the total estimated tax for the partnership is expected to exceed $100, estimated income tax payments are required using City of Detroit Income Tax Partnership Quarterly Estimated Payment Voucher (Form 5461)

To correct a return filed previously, use City of Detroit Income Tax Partnership Return (Form 5458).
