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.
SUW and CTYW e-filing
SUW and CTYW monthly/quarterly and annual tax returns (with or without payment) may be e-filed directly to Treasury using approved tax preparation software. Treasury accepts returns uploaded through the Michigan Treasury Online (MTO) bulk e-file application, or transmitted by a Transmitter through a Web Service. For additional information, review the E-File Tax Preparer Handbooks below or contact your software provider.
Beginning with tax year 2018, employers with more than 250 employees are required to e-file the Sales, Use and Withholding Taxes Annual Return (Form 5081) and the Sales, Use and Withholding Taxes Amended Monthly/Quarterly Return (Form 5082), if amending.
Michigan does not have an e-file mandate for CTYW tax returns.
