Sales tax · Agency: Michigan Department of Treasury
- Resale certificate
- Michigan Sales and Use Tax Certificate of Exemption (3372)Get the official form →
- How long it's valid
- One-time or blanket. A blanket certificate needs no renewal while a 'recurring business relationship' exists (no more than 12 months between sales); otherwise a blanket certificate stays in effect up to four years (or a shorter agreed period stated on the form). Sellers retain exemption records at least four years.
- Seller's permit
- Sales Tax License — Free. Treasury FAQ: 'No, there is not a fee for a sales tax license.' Register online via Michigan Treasury Online (MTO) eRegistration (authenticated in 10–15 minutes) or mail Form 518 (4–6 weeks). Wholesalers are not issued sales tax licenses. Sellers at only one or two events a year may instead file Form 5089 (Concessionaire's return).Register with Michigan Department of Treasury →Renewal: Sales tax licenses are issued yearly and valid January–December of the tax year shown; current license is printed from MTO.
- Buyer registered in another state?
- Yes — a purchaser not required to be licensed in Michigan may present a valid sale-for-resale exemption certificate (Form 3372, SST or MTC); wholesalers claim 'For Resale at Wholesale' without a Michigan number. (RAB 2016-14; RAB 1988-34.)
- Multistate forms
- RAB 2016-14 lists acceptable formats: Form 3372; any certificate in a current Sales and Use Tax administrative rule; the MTC Uniform Sales and Use Tax Certificate; a compliant purchase order; the SST Certificate of Exemption; or the required statutory information in another format (e.g., signed letter on letterhead). For 'resale at retail' the seller must obtain the purchaser's sales tax license number (MCL 205.68(1)); 'resale at wholesale' requires no number (wholesalers are not licensed).
- Drop shipments
- RAB 1988-34 (drop shipments, MCL 205.54k/205.94i): if an out-of-state seller not required to be licensed in Michigan gives the Michigan shipper a valid sale-for-resale exemption certificate, the Michigan shipper may be relieved of tax if it retains the certificate and supplies Treasury an annual information list of the out-of-state sellers and Michigan ship-to customers; the Michigan purchaser then owes use tax. (Bulletin dates from 1988.)
- Good to know
- Michigan has no local sales taxes; state rate is 6%.
- Contractors are not licensed for sales tax and use Form 3520 (Contractor Eligibility Statement) for qualifying exemptions.
- MTC note: a seller with a properly completed certificate is generally not liable even if the purchaser improperly claims an exemption (limited exceptions such as fraud).
