Do you have sales tax nexus in Oklahoma?

Good news! You only have to begin thinking about Oklahoma sales tax if you have sales tax nexus in Oklahoma.

“Sales tax nexus” is just a fancy way of saying “significant presence” in a state.

Oklahoma considers a seller to have sales tax nexus in the state if you have any of the following in the state:

• An office or place of business
• A salesperson, contractor, installer or other representative of the business doing business in the state
• Goods in a warehouse, distribution center or other place of business
• Delivery of merchandise in Oklahoma in vehicles owned by the taxpayer

You can click here to read exactly what the Oklahoma Department of Revenue (Oklahoma’s taxing authority) has to say about what constitutes sales tax nexus in Oklahoma (page 8 - “Place of Business.”) In 2016, Oklahoma passed a law attempting to declare that some out-of-state sellers with no significant presence in the state also have Oklahoma sales tax nexus. You can read more about the Oklahoma Retail Protection Act of 2016 here.

Do you have economic nexus in Oklahoma?

Effective November 1, 2019, Oklahoma considers vendors who sell at least $100,000 in the previous 12 months in the state to have economic nexus. This means the state considers these vendors obligated to collect sales tax from buyers in the state. You can read Oklahoma’s economic nexus guidance for sellers here and you can read more about economic nexus in every state here.

Is what you’re selling even taxable?

You’ve probably read this far because you realized you have sales tax nexus in Oklahoma. Your next step is to determine if what you’re selling is even taxable.

Services in Oklahoma are generally not taxable. So if you’re a music teacher or an electrician, you’re in luck and you don’t have to worry about sales tax. But watch out – if the service you provide includes creating or manufacturing a product for sale, you may have to deal with the sales tax on products.

Tangible products are taxable in Oklahoma , with a few exceptions, such as certain prescription medications.

So if you sell toys, then charge sales tax to your Oklahoma customers.

But if you’re a freelance blogger, don’t charge sales tax to your Oklahoma customers.

If you have sales tax nexus in Oklahoma and your products are taxable, your next step is to register for a sales tax permit.

How to Register for a Sales Tax Permit in Oklahoma

Sellers with sales tax nexus in Oklahoma must apply for an Oklahoma sales tax permit.

Don’t skip this step! Many states consider it unlawful to collect sales tax in their name without a permit. Go here for more on how to register for a sales tax permit in Oklahoma.

How to Collect Sales Tax in Oklahoma

So you’ve determined that you have sales tax nexus in Oklahoma and what you’re selling is taxable. And you’re all set and registered for your Oklahoma sales tax permit.

The next step is to determine how much sales tax to collect.

If you are based in Oklahoma and selling to a buyer with a ship to address in Oklahoma, charge sales tax based on the sales tax rate at the ship to address.

Example: You live and run your business in Muskogee, OK in the 74401 zip code. The total sales tax rate in Muskogee is 9.15%. But you make a sale to a customer in Enid, and ship the package to the 73701 zip code, where the combined total sales tax rate is 8.85%. Charge your customers 8.85% sales tax rate.

If you are not based in Oklahoma, but have sales tax nexus in Oklahoma you are considered an Oklahoma “remote seller.” This is where things get tricker, since remote sellers are required to collect “use tax,” which is similar to sales tax, but can vary slightly from Oklahoma sales tax rates.

You can look up your local sales tax rate with TaxJar’s Sales Tax Calculator or by going to TaxJar.com/mobile on your mobile device.

Should you collect sales tax on shipping charges in Oklahoma?

As long as you separately state the shipping charges on your bill to your customer, you do not have to charge sales tax on shipping.

But if you include shipping in the price of the product you sell the customer, then shipping is considered part of the taxable transaction and Oklahoma declares that you must collect sales tax on shipping.
