How to Apply for a Michigan Sales Tax Exemption Certificate

Michigan uses Form 3372 (Michigan Sales and Use Tax Certificate of Exemption) as the standard document for claiming tax-exempt purchases. Buyers must complete Form 3372 and provide it to the seller at the time of purchase to avoid paying the 6% sales tax. The form requires the buyer to specify the reason for exemption (resale, agricultural, industrial processing, nonprofit, government, etc.) and include their sales tax license number or federal EIN where applicable.

Purpose: Used for transactions exempt from sales tax, such as purchases by government agencies, nonprofit organizations, or for resale purposes.

Usage: The buyer provides the completed Form 3372 to the seller at the time of purchase to avoid paying sales tax.

Retention: Sellers must keep a copy of the certificate on file to validate tax-exempt transactions in case of an audit.

Expiration: A Michigan blanket certificate remains effective for four years unless a shorter period is indicated, and it does not need to be renewed while a recurring business relationship continues with no more than 12 months between sales.
