How to Use the Missouri Sales and Use Tax Exemption Certificate
The short answer. The Missouri Sales and Use Tax Exemption Certificate (Form 149) lets a business buy goods for resale without paying Missouri sales tax. The buyer fills in and signs the Missouri Sales and Use Tax Exemption Certificate and gives it to the seller. Missouri publishes a form, but any document that carries the information the state requires is accepted.

Who May Give a Resale Certificate in Missouri
Whether a buyer must hold a Missouri retail license to buy for resale depends on the circumstances. To buy goods for resale, give your sales tax ID number and home state; a Missouri retailer must give a Missouri Tax I.D. Number, and a buyer registered elsewhere may give its home state's number. To buy taxable services for resale you must be registered in Missouri. A manufacturer or wholesaler buying for wholesale may not need a Missouri Tax I.D. Number.
The buyer fills in and signs the Missouri Sales and Use Tax Exemption Certificate and gives it to the seller.
Which Documents Are Accepted
Missouri publishes a form, but any document that carries the information the state requires is accepted.
The Multistate Tax Commission lists Missouri among the states that accept its uniform resale certificate.
We have not confirmed whether Missouri accepts the Streamlined Sales Tax Certificate of Exemption; check with the Missouri Department of Revenue.
What the certificate must contain is set by Missouri law, cited in the sources.
How Long It Lasts
The Missouri Sales and Use Tax Exemption Certificate does not expire. The seller may rely on it for your future purchases unless it does not cover the purchase or the seller can no longer rely on it in good faith.
One blanket certificate may cover repeat purchases from the same seller.
For Sellers Who Accept One
Under Missouri's law, a seller that takes a resale certificate in good faith is relieved of liability for the tax on that sale.
The state's general sales tax records period is at least 3 years.
Worth Knowing in Missouri
The seller must write the name of the purchaser claiming the exemption on each invoice or bill of sale. An unsigned exemption certificate is not valid.

Frequently Asked Questions
This guide is general information, not legal or tax advice, and reading it does not create an attorney-client relationship. It reports what each state's tax agency, or the multistate bodies' published notes, say about the certificate a buyer gives a supplier when it buys goods for resale, with the sources this page cites. It cannot tell you whether your own purchase qualifies: that turns on what you buy, whether you resell it, and where you are registered, and a certificate given for a purchase that does not qualify can leave the buyer owing the tax. Confirm your own position with the tax agency named on this page before you give or accept one.
