Secretary of State
The Michigan Department of Treasury requests dealers contact their Sales, Use, and Withholding Taxes Division with any questions about the collection of sales tax. Treasury requests dealers not ask Secretary of State branch offices any sales tax questions, as final jurisdiction with all tax matters rests with the Department of Treasury.
Dealers with any questions about the proper collection of sales or use tax should contact the Michigan Department of Treasury customer service line at 517-636-4230.
