Register With the Department of Revenue First
Form 149 only works if you already hold a Missouri sales tax license. Any business making retail sales of goods or taxable services in Missouri must register with the Department of Revenue.2Missouri Department of Revenue. Business Tax Registration – Requirements You can register online through the MyTax Missouri portal or submit a paper Missouri Tax Registration Application (Form 2643).3Missouri Department of Revenue. Form 2643 – Missouri Tax Registration Application There is no fee to file the application.

Security Bond for New Applicants
New retail sales tax license applicants must post a security bond set at three times the estimated average monthly tax liability.

Remote Sellers
If your business is based outside Missouri and sells into the state, you must register and collect vendor’s use tax once your gross receipts from taxable sales into Missouri exceed $100,000 in a calendar year.6Missouri Department of Revenue. Remote Seller and Marketplace Facilitator FAQs After that, you can use Form 149 or the Multistate Tax Commission’s uniform resale certificate for tax-free inventory purchases.
Filling Out Form 149
Form 149 is a one-page document you complete as the buyer.1Missouri Department of Revenue. 149 – Sales and Use Tax Exemption Certificate Each section asks for:
- Purchaser information: full legal business name, physical address, and either your Social Security Number or FEIN.
- Missouri Tax I.D. Number from your retail license, which links the certificate back to your registered business.
- Reason for exemption. Buyers stocking inventory to resell check the resale box. The form also lists manufacturing, ingredient or component parts, research and development, and other categories.
- Description of the property you are buying.
- Signature and date from an authorized representative. The signature line carries a perjury declaration, so you are certifying under penalty of law that the information is true.
Always download the current version straight from the Department of Revenue site so you are not working from an outdated revision.
Give It to Your Vendor, Not the State
You hand Form 149 to your supplier. The vendor keeps the completed form as proof that the sale to you was not a taxable retail sale.1Missouri Department of Revenue. 149 – Sales and Use Tax Exemption Certificate Most vendors accept a scanned or emailed PDF; some prefer a physical original.
Under Missouri law, the seller generally bears the burden of proving a sale was not taxable, which is why they need your signed certificate on file. But if the exemption you claimed turns out to be improper, the Director of Revenue can collect the unpaid tax, interest, and penalties directly from you.7Missouri Revisor of Statutes. RSMo Section 144.210
Using One Form 149 as a Blanket Certificate
You do not need a fresh Form 149 for every order from the same vendor. A single completed certificate can cover all future qualifying purchases from that supplier, as long as your business status and the nature of the purchases stay the same.1Missouri Department of Revenue. 149 – Sales and Use Tax Exemption Certificate
Sellers are expected to update the resale exemption certificates in their files every five years.8Missouri Department of Revenue. Form 149T – Exemption Certificate for Tire and Lead-Acid Battery Fee If your registration lapses or the mix of products you resell changes, send the vendor a new certificate promptly. Continuing to use an outdated or inaccurate one exposes both sides to back taxes and penalties.
Out-of-State Buyers Purchasing From Missouri Vendors
If your business is registered in another state but you are buying goods from a Missouri vendor for resale, you can still claim the exemption. On Form 149, put your home state’s retail sales tax registration number where the Missouri Tax I.D. Number goes and identify the state that issued it.1Missouri Department of Revenue. 149 – Sales and Use Tax Exemption Certificate
Missouri also accepts the Multistate Tax Commission Uniform Sales and Use Tax Resale Certificate as an alternative.9Multistate Tax Commission. Uniform Sales and Use Tax Resale Certificate – Multijurisdiction One MTC form covers many jurisdictions, which is useful if you regularly buy across state lines. Even when property is delivered outside Missouri, the state warns that certain facts and circumstances can still make the transaction subject to Missouri tax.
If You Take Resale Inventory for Personal Use
If you buy something tax-free with Form 149 and then pull it from inventory for personal use or business consumption instead of reselling it, you owe sales tax on that item. The tax is based on your original cost, not the retail price you would have charged a customer. Report and remit both the 4.225 percent state tax and any applicable local sales tax on your next sales tax return.10Missouri Secretary of State. 12 CSR 10-11.120 – Items Taken From Inventory
Take a furniture store owner who moves a showroom chair into their own office. They owe state and local sales tax on what the store paid for the chair, and the local rate is the one for the county where the chair was originally purchased, not where it ends up in use. Missed self-reporting of inventory withdrawals is a common audit trigger.
Penalties for Misusing the Certificate
Using Form 149 to buy items for personal use, or stretching the exemption beyond what your registration supports, carries real consequences. Missouri’s penalties escalate based on whether the misuse was a mistake or deliberate.
- Back taxes plus daily interest and a 5 percent failure-to-pay penalty. If you did not file the required return at all, the penalty is 5 percent of the tax due for each month late, capped at 25 percent.11Missouri Department of Revenue. Maintain Sales/Use Tax
- A fraud penalty equal to 25 percent of the underpayment if the Director of Revenue finds fraud or evasion, added on top of the tax itself.12Missouri Senate. Missouri Revised Statutes – Chapter 144 Sales and Use Tax
- Criminal prosecution for willfully filing a false return or willfully failing to pay with intent to defraud: a fine of up to $10,000, imprisonment for up to one year in county jail or two to five years in state prison, or both, plus costs of prosecution.12Missouri Senate. Missouri Revised Statutes – Chapter 144 Sales and Use Tax
- No statute of limitations on fraudulent returns. A legitimate mistake has a limited assessment window; fraud leaves you exposed indefinitely.12Missouri Senate. Missouri Revised Statutes – Chapter 144 Sales and Use Tax
The perjury declaration on Form 149 means signing the form with false information is itself a basis for prosecution. Treat every certificate you sign as a sworn statement that could be pulled and reviewed in an audit years later.
