Oklahoma Sales Tax FAQ

Oklahoma Sales Tax FAQ 


By now, you may have already contacted the Oklahoma Tax Commission and applied for an Oklahoma sales tax permit. 

Once you have a license to collect and remit sales taxes in Oklahoma, you will probably be asking yourself two questions: 

  • When do I charge a sales tax in Oklahoma?
  • What goods and services are subject to sales taxes in Oklahoma? 

We are going to go over some common questions that our clients have asked. We believe these questions will help you appreciate the nuances of taxable goods so you can be confident in fulfilling your tax obligations. 

Let’s start with the first question…



What goods and services are considered taxable in Oklahoma?

The following items are all taxable in the state of Oklahoma: 

  • Sales of tangible goods at retail.
  • Repairs or alterations of tangible personal property.
  • Property rentals, leases, or licenses [e.g. commercial, mini-warehouse]
  • Selling service warranty contracts.
  • Short-term rentals for living accommodations (e.g. motel/hotel, beach houses, condos, timeshares, vacation homes, or RV homes).
  • Rental/lease of personal goods (e.g.: machinery, vehicles, equipment, or other property).
  • Charges for admission to any place of amusement, sport, or recreation.
  • Manufacturing or producing goods for retail sales.
  • Operating vending machines or amusement rides.
  • Services are mostly exempted 



The bottom line is …

Your business must pay taxes on sales of any non-exempt goods, and some taxable services.




Let’s now review some of our clients’ frequently asked questions:

  • Is Oklahoma an Origin or Destination Sales Tax State?
  • What creates a sales tax nexus in Oklahoma?
  • What is the economic threshold in Oklahoma?
  • Does Amazon have fulfillment centers in Oklahoma?
  • Does Oklahoma have a Click-Through Nexus?

To best understand your tax obligations, new businesses need to consider how they are doing business and the type of relationships they have with buyers and any third parties to their transactions. 

 Let’s discuss some questions that will help you understand the nature of your small business and the subsequent tax implications.   



Is Oklahoma an origin or destination-based sales tax state?

Oklahoma is a Destination-based sales tax state, which simply means you charge sales tax based on the location of the purchaser rather than that of the seller. Local cities, counties, and unincorporated areas may choose to add an additional tax. Oklahoma’s Tax Commission offers a website to check the sales tax rate based on an address.



What creates sales tax nexus with the state of Oklahoma?  

Having nexus, also known as "sufficient business presence,” with Oklahoma means your business has established a taxing connection with a state. When this happens, you are required to collect and remit sales tax in Oklahoma because you created a sales tax Nexus.

Even if your business maintains its main headquarters in another state, you may still have to charge and pay sales tax to the Oklahoma Tax Commission even if you never step foot in Oklahoma.   

So, how do you create a sales tax Nexus in Oklahoma?


A business establishes a nexus in Oklahoma by:

  • having a business location in Oklahoma;
  • having property stored in Oklahoma;
  • employing any person in Oklahoma;
  • contracting with a salesperson or other agent in Oklahoma;
  • leasing equipment used in Oklahoma;
  • performing services in Oklahoma;
  • licensing the use of intangible property in Oklahoma, or transporting property in Oklahoma using the taxpayer’s vehicles.

Let’s talk a bit more specifically about where your goods are stored, such as in the instance of an Amazon warehouse. 



Does Amazon have fulfillment centers in Oklahoma?

No, Oklahoma has no distribution centers at this time.

This information is relevant for our customers who sell products on Amazon or are recognized as Amazon FBA (Fulfillment by Amazon) sellers. When Amazon stores products in one of its fulfillment centers in any state including, it triggers a sales tax requirement. 



Does Oklahoma have economic nexus?

Not yet, but coming soon! On May 16th, 2019, the governor of Oklahoma signed SB513 into law. This means that starting November 1st, 2019 certain remote sellers that otherwise lack Nexus in Oklahoma will be required to register. Any company with more than $100,000 in sales into Oklahoma is required to register for a sales tax permit.



Does Oklahoma have click-through nexus?

Yes! This means if you’re an affiliate sales or third party marketer, you may have a tax liability even if you don’t meet nexus another way. If revenue exceeds $10,000/quarter four quarters in a row, affiliate marketers will need to either register for and pay sales tax, OR send sales information to Oklahoma so they can assess use tax. For more information, OK COT offers this page for remote sellers..



Is Oklahoma a streamlined sales tax state?

Yep! Since October, 2005 Oklahoma has been a full member of Streamlined Sales Tax.

If you are planning on taking advantage of the Streamlined Sales Tax as a business, it is recommended you use a Certified Service Provider though businesses may opt to register themselves without a CSP. Ultimately the aim of streamlined sales tax is to simplify payment to multiple different states of sales and use tax. It isn’t required that you utilize them, but it can significantly reduce complexity to do so, especially if your business sells in multiple states.

Collecting Sales Tax in Oklahoma

Collecting Sales Tax in Oklahoma

By now you know if you are a business that has established a nexus with Oklahoma. So you have an understanding about whether, or when, you are required to collect sales tax. Knowing this is just half the battle! Now, we are going to help you with the next half of the battle: how to navigate the process of collecting taxes.

Let’s review some common questions our clients have asked regarding their Oklahoma Sales Tax obligations. 

  • How do I collect Oklahoma Sales Tax?
  • Who is eligible for Oklahoma Sales Tax exemptions?
  • What should I do if my customer is exempt from sales tax in Oklahoma?
  • What happens if I lose an Oklahoma nontaxable transaction certificate? 

After reading this, you will be better equipped to determine when --and when not-- to collect sales tax in Oklahoma.



How do I collect Oklahoma Sales Tax?

As we mentioned above, Oklahoma is a Destination-based state. So at the time of the transaction, tax should be collected based on the location of the purchaser. Your point-of-sale software should make this relatively simple, including accounting for any local surtaxes



What are the current Oklahoma Sales Tax rates?   

Oklahoma’s state-wide sales tax rate is 4.5% (since 1990! wow) at the time of this article’s writing, with potential local surtaxes bringing it as high as 11%. Since sales tax rates may change and do vary by location, we shall refer you to check out the Oklahoma Tax Commission tax rate lookup page. Any change will be reflected on that page.

It always helps to be accurate and up-to-date with this type of information! :) 



What is exempt from sales tax in Oklahoma

What is exempt from Oklahoma Sales Tax?

Here is a sample list of exemptions: 

  • Purchases for resale
  • Everyday clothing items
  • Medical supplies
  • Groceries 

Oklahoma does not have many exemptions beyond the standard ones listed above, but for more specificity they provide this PDF.



Who are eligible for Oklahoma Sales Tax exemptions?

At this point, you should know what products are exempt from sales tax in Oklahoma. You also want to know who may be exempt. 

Under Oklahoma law, the type of buyer or the way the goods will be used can qualify can buyer for a sales tax exemption. A good example of this is a merchant purchasing goods for resale, aka a wholesaler.

Other common examples of an exempt buyer may include:

  • Government agencies
  • Non-profit organizations
  • Religious groups
  • Out-of-state buyers (should their business not have nexus in their home state).

Note that a non-profit or contractor status doesn’t necessarily immediately confer tax-exempt status. 



What should I do if my customer is exempt from sales tax in Oklahoma?

Purchasers who are tax-exempt must have completed resale certificate (PDF) and must present their completed exemption certificate at the time of purchase. It is then incumbent upon the seller to hold on to this exemption certificate. Failure to do so may leave you unable to justify tax exempt sales.

Remember, you always want to collect and file a copy of the exempt certificate. Such certificates must be produced upon request in the event of an audit to justify tax-exempt sales.



What happens if I lose an Oklahoma Sales Tax exemption certificate?

Hmm... Obviously, this issue is best to be avoided! Imagine finding out you’ll be audited and discovering you cannot produce an exemption certificate for a buyer! That nightmare scenario would mean you could be held liable to pay all taxes on behalf of the buyer, plus relevant penalties ($500 per lapse in Oklahoma). This is a bad scene and can be avoided by taking proper care with your paperwork… which happens to be one of our specialties! :) 



Does Oklahoma have a sales tax holiday?

Yes! Oklahoma has a Back to School Tax Holiday during which clothing items that cost $100 or less are exempt. In 2019, the holiday is from Friday the 2nd to Sunday the 4th.





We have now covered who you need to collect sales taxes from, how to determine whether goods for sale are deemed taxable, what goods and services fall under tax exemptions, who is eligible for tax exemption certificates, and, finally, the process of collecting sales tax in Oklahoma state. 

Now that we’re this far down the rabbit hole there’s only one thing we need to learn about next… how to pay the piper!
