Michigan Resale Certificates: How to Use and Accept Form 3372

A resale certificate is one of the most useful sales tax documents for Michigan businesses that buy products for resale. When used correctly, it allows a buyer to purchase eligible inventory without paying sales tax up front, so tax is collected only when the item reaches the final customer.

Michigan does not issue a separate “tax exempt number” as proof of exemption. Instead, buyers generally claim a resale exemption by giving the seller a completed Michigan Sales and Use Tax Certificate of Exemption, Form 3372, or another acceptable exemption certificate format recognized by the state. The key is simple: the purchase must truly be for resale, and the buyer must provide the right documentation.

For businesses forming or expanding in Michigan, understanding resale certificates is important for cash flow, recordkeeping, and sales tax compliance. If you sell taxable products, buy inventory from suppliers, or run an ecommerce operation, this guide explains how the process works and how to avoid the most common mistakes.

What a resale certificate does

A resale certificate tells a supplier that the buyer is purchasing goods for resale rather than for final use. Because the item is not being consumed by the buyer, sales tax is not charged at the time of purchase.

That does not mean the tax disappears. It is collected later when the reseller sells the product to the end customer, assuming the final sale is taxable. In other words, the resale certificate prevents tax from being charged twice on the same item.

In Michigan, resale purchases are handled through the broader sales and use tax exemption process. The seller must receive a valid claim of exemption, and the buyer should be prepared to support that claim if the transaction is reviewed later.

Who can use a resale certificate in Michigan

A business can typically use a resale exemption when all of the following are true:

• The business is buying tangible personal property.
• The property is being purchased for resale, not for internal use.
• The buyer can support the exemption with proper documentation.
• The seller has reason to believe the exemption is valid.

This matters most for:

• Retailers purchasing inventory from wholesalers or distributors
• Ecommerce sellers sourcing products for online resale
• Resellers using drop-shipping arrangements
• Wholesalers buying goods that will be sold again downstream

If the item is used in the business instead of being resold, the exemption does not apply.

Michigan’s official form and acceptable proof

Michigan’s main exemption document is Form 3372, Michigan Sales and Use Tax Certificate of Exemption. Michigan also accepts other permitted exemption formats in some situations, including the Multistate Tax Commission’s uniform certificate and the Streamlined Sales and Use Tax Agreement certificate.

For most businesses, Form 3372 is the clearest option because it is widely recognized by Michigan sellers and directly tied to the state’s exemption rules.

How to get ready to use a resale certificate

Before you hand a resale certificate to a supplier, make sure your business records are organized. A supplier may want the exemption form before completing the sale, and your own files should show why the purchase qualified.

A practical preparation checklist looks like this:

1. Confirm that the goods are being bought for resale.
2. Make sure the buyer name matches the legal business name.
3. Keep the business address and contact details current.
4. Identify the correct exemption basis on the form.
5. Keep a copy of every certificate you issue or receive.

If your business sells taxable goods at retail in Michigan, you should also confirm whether you need a sales tax license. Michigan’s Sales Tax License FAQ explains that retail sellers register for sales tax through Michigan Treasury Online.

How buyers should use a resale certificate

When you buy items for resale, the resale certificate should be given to the supplier before or at the time of purchase. The supplier uses the completed form to document why sales tax was not charged.

A proper buyer workflow usually includes:

• Filling out the purchaser section completely
• Describing the purchase as “for resale at retail” when that is the correct basis
• Providing any required license or registration information
• Giving the completed certificate to the supplier
• Keeping an internal copy for your records

Do not use a resale certificate for office supplies, equipment, packaging that is not resold as part of the taxable product, or any other purchase that is not actually for resale.

How sellers should accept a resale certificate

Sellers have the responsibility to collect tax unless the buyer provides a valid exemption claim. Michigan’s guidance makes clear that the seller should keep documentation showing why the sale was exempt.

When accepting a resale certificate, sellers should:

1. Obtain the completed exemption form before finalizing the tax-exempt sale.
2. Check that the buyer identified the reason for exemption clearly.
3. Confirm the goods match the claimed resale purpose.
4. Retain the certificate and related records.
5. Keep transaction details in case the sale is reviewed later.

Michigan guidance also warns sellers not to rely on a tax exempt number alone as proof of exemption. In general, a FEIN by itself is not enough. The seller needs a valid exemption claim, not just an identification number.

What sellers should keep on file

Recordkeeping is a major part of resale-certificate compliance. Michigan expects sellers to preserve enough information to support the exempt sale if it is questioned later.

Helpful records include:

• Buyer name and address
• Date of the sale
• Description of the goods sold
• Purchase amount
• Type of exemption claimed
• Buyer’s sales tax license or registration number, when applicable

Good records matter because the supplier is the party that initially decides whether to charge sales tax. If the exemption claim is unsupported, the seller may be responsible for the tax.

Resale certificate vs. sales tax license

A resale certificate and a sales tax license are related, but they are not the same thing.

A resale certificate is used to buy inventory tax-free from a supplier when the goods will be resold.

A sales tax license is used by a business that sells taxable goods to customers and must collect and remit Michigan sales tax.

Many retail businesses need both:

• The sales tax license lets the business collect tax on taxable sales.
• The resale certificate lets the business buy inventory without paying tax upfront.

That distinction is important for new founders. If you only sell wholesale, the documentation may look different than it does for a traditional retail seller. Michigan’s Exemptions FAQ explains that retailers may purchase tangible personal property exempt from sales and use tax if the purchase is for resale at retail.

Common mistakes to avoid

Resale certificate problems usually come from simple documentation errors rather than complex tax planning.

Avoid these mistakes:

• Using a resale certificate for personal purchases
• Claiming exemption on items that will be used by the business
• Leaving the exemption form incomplete
• Failing to keep copies of issued and received certificates
• Accepting a certificate without checking whether the goods really qualify
• Treating a FEIN or tax ID number as enough proof by itself

These mistakes can trigger tax assessments, penalties, or disputes with suppliers.

Special considerations for wholesalers and ecommerce sellers

Wholesalers and ecommerce sellers often use resale certificates frequently, so their systems need to be disciplined.

If you operate an online store, make sure your purchasing workflow clearly separates inventory purchases from operating expenses. Inventory bought for resale belongs in your exemption process. Assets, software, subscriptions, and office supplies usually do not.

If you drop-ship goods, your supplier may still need exemption documentation before shipping the item tax-free. The same core rule applies: the purchase must be made for resale, and the seller must have proper proof.

Compliance checklist for Michigan businesses

Use this checklist to keep resale certificate handling clean and consistent:

• Register for the correct Michigan tax accounts if you sell taxable products.
• Use Form 3372 or another valid exemption certificate format.
• Apply the resale exemption only to qualifying purchases.
• Keep copies of all exemption certificates.
• Maintain records for each exempt transaction.
• Review your purchasing process regularly.
• Update your business details if they change.

A simple process now can prevent a costly tax issue later.

Frequently asked questions

Do Michigan resale certificates expire?

The form itself is not the same thing as a retail sales tax license. The practical issue is not just the form date, but whether the exemption claim is still accurate and supported by current business information.

Can a seller refuse a resale certificate?

Yes. If the certificate is incomplete, inconsistent, or does not support the sale, the seller can charge sales tax and request better documentation.

Does every business need a resale certificate?

No. Only businesses that buy goods for resale need to use one. Service businesses that do not resell tangible products may not need it.

Is a resale certificate the same in every state?

No. States have different rules, forms, and documentation standards. A certificate that works in one state may not automatically satisfy another state’s requirements.

Final takeaway

Michigan resale certificates are straightforward once you understand the rule: buy for resale, document the exemption correctly, and keep good records. Buyers use Form 3372 or another approved certificate format, while sellers must verify and retain the exemption claim before treating the sale as tax-free.
