Where do I register my business for Michigan taxes?
Michigan Treasury Online (MTO) at mto.treasury.michigan.gov is where you register for most state business taxes. This includes sales tax if you sell taxable goods or services, use tax, withholding tax if you have employees, and corporate income tax if you operate as a corporation.
Creating an MTO account is free and the registration process is straightforward. You can complete most registrations online in one session. The system will ask for your federal EIN, business formation details, owner information, and the physical address where your business operates. Have these ready before you start.
Sales tax registration is required if your business sells taxable products or certain services. Once registered, you receive a sales tax license that must be displayed at your business location. Michigan requires monthly, quarterly, or annual filing depending on how much you collect.
If you hire employees, you need to register for withholding tax through MTO so you can remit the state income tax withheld from employee wages. This is separate from federal withholding, which goes to the IRS.
Unemployment insurance is not handled through MTO. You register for that through the Michigan Unemployment Insurance Agency (UIA) at michigan.gov/uia. This is required once you have employees and covers your state unemployment tax obligations. Many new business owners miss this step because they assume everything goes through one portal.

Staying compliant is where most small businesses run into trouble.
