Diesel (Motor) RepairAgency: Department of State
Required State License(s):
The Michigan Department of State's Bureau of Regulatory Services (BRS) licenses and regulates Michigan's motor vehicle repair facilities and mechanics. For more information visit our website www.michigan.gov/sos or call 1-888-SOS-MICH (888-767-6424).
There is NO state license required for small engine repair (lawn mower engines, etc.) However, if parts are sold to an individual who will be repairing their own mowers, a sales tax license is required with the Department of Treasury. You may call the Michigan Department of Treasury at (517) 636-4660 and request a 518 form.
Personalized sales tax returns and a payment schedule will be mailed within four to six weeks after the registration has been processed. If you have questions about this process, please call the Michigan Department of Treasury at (517) 636-4730.
