Michigan e-file - Sales, Use and Withholding (SUW) and City Income Tax Withholding (CTYW) Tax Preparer
The State of Michigan is working with tax preparers, payroll service providers and software developers to encourage taxpayers to e-file their SUW and CTYW tax returns. E-file is secure, fast, convenient, and helps save Michigan taxpayer dollars.
E-file. Good for you. Good for Michigan.
NEW! - Additional e-file Options Announced
Treasury now supports two e-file methods when using Treasury approved tax preparation software. SUW and CTYW tax returns may be submitted directly to Treasury by being uploaded through the Michigan Treasury Online (MTO) bulk e-file application (new), or by being transmitted by a Transmitter through a Web Service. For additional information, review the SUW or CTYW E-File Tax Preparer Handbooks below or contact your software provider.
SUW and CTYW e-filing
SUW and CTYW monthly/quarterly and annual tax returns may be e-filed directly to Treasury using approved software. Payments can also be submitted electronically with the tax return, when supported by the software.
Michigan does not have an e-file mandate for SUW or CTYW tax returns. However the SUW Fuel Supplier and Wholesaler Prepaid Sales Tax Schedule (Form 5083), Fuel Retailer Supplemental Schedule (Form 5085) and Vehicle Dealer Supplemental Schedule (Form 5086) are not eligible for paper filing; they must be e-filed.
