How can we help?

New company registration in Michigan

Michigan tax agencies

  • Michigan Department of Treasury - income tax withholding
  • Michigan Unemployment Insurance Agency- unemployment tax

Register a new company

During the registration process you will be asked if you are using a payroll service and need a power of attorney form to be filled out. Once you enter in the MI information in your Gusto account, we will formulate this Power of Attorney (POA) form for you to electronically sign along with the other forms.

Income tax withholding and Unemployment tax

You can register for both income tax withholding and unemployment tax online. At the bottom of the page, select e-Registration to begin. If you have any questions regarding registration, please call the agency at (313) 456-2188.

You will receive your UIA Employer Account Number a few days after registering. For new employers in Michigan, your total unemployment rate will be 2.70% plus the variable OA rate. If you have any questions regarding your tax rate, please contact the agency at (313) 456-2010.

Local taxes

Multiple cities in Michigan levy an income tax on residents and nonresidents who work in these specific cities. These taxes are typically 1% income tax on residents and .5% on nonresidents. The cities of Detroit, Grand Rapids, Highland Park and Saginaw have rates that differ from the rest. 

Gusto will handle the payment of these taxes but as a business owner you will need to register with the city/cities that your employees are working in. Registration in each city is unique. By clicking on the respective city below you will be provided with the form that needs to be mailed to that city to register. 

Troubleshoot Unemployment Insurance Agency authorization issues

Some agencies require special authorization for Gusto to pay or file your taxes.

To ensure successful authorization, please verify that the following information you have entered into Gusto matches what is on file with the Michigan Unemployment Insurance Agency:

  • FEIN - Federal Employment Identification Number
  • Unemployment Account Number (UIA)

If Gusto is having trouble gaining access to your account, please verify that the above information matches exactly what the agency has on file by giving them a call at (313) 456-2010.
