How to Get a Certificate of Exemption in Oklahoma

If you have recently launched or are planning to launch a business that will sell products or services in Oklahoma, you may want to get a certificate of exemption, or several of them, before you start doing business, as this can save you a lot of time and money. 

This document is known as a resale certificate in most other states, and attaining one’s a relatively simple process, as detailed in this step-by-step guide. 

What is a Certificate of Exemption?

If your business has a valid certificate of exemption you can buy goods from a wholesaler without paying Oklahoma sales tax, though you may pay a use tax. Depending on the size of your business, this can save you tens of thousands of dollars each year. 

The catch is that whenever you do use a certificate of exemption to purchase goods, you are legally bound to resell those items and collect sales tax when you do so. If you do not resell those items, or fail to collect sales tax, the punishment could be costly fines or potential jail time.

Keep in mind, each certificate of exemption, also known as a resale license, applies to a single vendor. This means you’ll need a certificate of exemption for each one of your vendors. 

You cannot use a certificate of exemption to buy items you do not intend to resell, such as a new computer for your business. This would be tax fraud, a felony offense. You are only able to buy items tax-exempt if you are going to collect sales tax on them later.

Not all wholesalers will accept certificates of exemption, nor do they have to. They may choose not to because of the risk of expired or false certificates, which would put the wholesaler on the hook for the sales tax.

How to Apply for a Certificate of Exemption in Oklahoma

In Oklahoma the resale certificate is known as the “certificate of exemption” and you’ll need to obtain the form from the Tax Commission. The certificate is not filed with the state of Oklahoma, it’s simply kept on file by the seller.

In a few states, a seller’s permit, or sales tax permit, also serves as a certificate of exemption that applies to all vendors. But in most states, including Oklahoma, you’ll need a seller’s permit as well as certificates of exemption for each of your vendors. 

The seller’s permit identifies you with your state as a collector of sales tax. If you sell tangible personal property or goods you are required to have a sales tax permit. In some states, even a service provider like a lawyer is required to have a sales tax permit and collect state sales tax.

The certificate of exemption applies to items that you buy for resale, or for parts that you buy to manufacture something for sale.
