Oklahoma rules in plain English

Oklahoma does not have an official resale certificate form. The Oklahoma Tax Commission instead lists what a seller must keep. Give your supplier a copy of your Oklahoma sales tax permit. If you cannot, give your business name, address, permit number and the permit's expiration date. Add a signed statement that you are buying the items to resell them. You can also use the Multistate Tax Commission uniform certificate or the Streamlined Sales Tax certificate of exemption. The seller must have your documents within 90 days of the sale. If you buy regularly and state that all purchases are for resale, one certification covers later purchases until your permit expires. When you renew your permit, expect the seller to ask for the new one. Sellers can look up your permit in OkTAP, the Commission's online system. Contractors cannot buy building materials for resale. If you misuse resale documents or use the items yourself, you owe the tax and can be fined $500.

Oklahoma resale certificate FAQ

What form do I use for an Oklahoma resale certificate?

Oklahoma does not require one specific form. The Oklahoma Tax Commission accepts any certificate that includes the buyer's name, address, permit number, a description of the property, and a signed statement that it is purchased for resale. Our generator produces a signed certificate with every required element.

Does Oklahoma accept the MTC uniform resale certificate?

Yes. Oklahoma accepts the Multistate Tax Commission's Uniform Sales and Use Tax Certificate, which is convenient when you buy from vendors in several states. The Streamlined Sales Tax exemption certificate is accepted as well.

Can an out-of-state business use a resale certificate in Oklahoma?

Yes, with conditions. OAC 710:65-7-8 and 68 O.S. 1365(C) are written around a resale number issued by the Commission; a non-Oklahoma number is clearly accepted for drop shipments under the SST certificate. Acceptance outside drop shipments was not confirmed.

Can I give a vendor one blanket resale certificate in Oklahoma?

Yes. A blanket certificate in Oklahoma covers every qualifying purchase from that vendor going forward, typically described as "All tangible personal property for resale".

How long is an Oklahoma resale certificate valid?

Resale documentation is good until the buyer's sales tax permit expires. For continued sales the vendor must have a permit on file for each renewal interval; if no renewal interval is set by statute, the period is deemed three years.

What happens if I misuse an Oklahoma resale certificate?

If the OTC finds a buyer improperly presented exemption documents or used the property for a non-exempt purpose, the buyer owes the tax and can be fined $500, and the OTC may collect from the buyer instead of the vendor.

When can an Oklahoma seller rely on a resale certificate?

A vendor is relieved of the tax if it in good faith timely accepts properly completed documentation. Good faith requires strict compliance with the requirements, and timely means the vendor has the documents within 90 days after the sale. Without the buyer's Commission-issued resale number, a sale is presumed not to be for resale.

How do I verify an Oklahoma resale certificate?

Check the buyer's Sales tax permit number with the online lookup from the Oklahoma Tax Commission, linked under Sources on this page. Keep a record of the check with the certificate.
