General MTO FAQs

What is Michigan Treasury Online (MTO)?

MTO is an e-services portal that allows businesses secure, 24/7 online access to their Treasury business accounts. This e-service allows taxpayers or their representatives to electronically file and pay Sales, Use and Withholding (SUW) taxes, update account information and view Treasury issued correspondence.


How do I access MTO?

Michigan Business One Stop (MBOS) has been eliminated as a step to access MTO. Go to Michigan Treasury Online. View the step-by-step instruction guides including log-in instructions for new or returning users.


Which browsers are compatible with MTO?

MTO is supported by Internet Explorer versions 10 and higher, Google Chrome, Firefox, and Safari.


Why should I sign up for MTO?

Some of the benefits of MTO are:

  • Registering for business taxes
  • Free and secure 24/7 online access to your Treasury business account
  • Updating your business account information
  • E-filing tax returns and making e-payments for SUW taxes
  • Viewing Treasury issued correspondence.


  • MBOS has been removed
  • Simplified process via a single set of log-in credentials: customers need only one username and password to enter the site, file a return, and make an e-payment
  • Reduction in the number of steps to create a user profile and create a new business relationship
  • Authorized users have the ability to establish their own relationship (self-delegate) to a business

If I am a taxpayer who files SUW taxes by paper, uses commercial software, proprietary software, and/or a Payroll Service Provider (PSP), do I have to sign up for MTO?

MTO is an optional service for most SUW taxpayers. If you are a 4%/6% filer (providing heating sources to residential customers), you are required to file via MTO. If you are an accelerated filer or you remit credit schedules with your SUW return (gasoline/diesel or vehicle dealer supplemental reports), you are required to file via MTO or bulk e-file.

For the remaining SUW taxpayers, some of the benefits to signing up for MTO are:

  • Registering for business taxes
  • Secure 24/7 online access to your Treasury business account
  • Updating your business account information
  • Viewing Treasury issued correspondence.
