Oklahoma Sales Tax in Plain Words

What gets taxed, and how to get the permit.

This page is general information, not tax or legal advice.

What gets taxed?

In Oklahoma, sales tax must be charged on all transfers of tangible personal property in the state. Tangible personal property means physical things you can touch — goods you sell, hand over, or rent out.

Sales tax is also charged on certain services that the law specifically names. The Oklahoma Tax Commission (OTC) Sales and Use Tax page is the place to check the current list of those named services.

Do services get taxed in Oklahoma?

Most services are NOT taxed in Oklahoma.

You may see tables from vendors that say "services are taxable" in Oklahoma, as if that were true for services in general. That is not right. Only some services — the ones the law specifically names — are taxed. Most services are not.

If you sell a service, check the OTC Sales and Use Tax page for the named list before you charge tax. Do not guess.

How much is the tax?

The state rate is 4.5% of gross receipts — that is, 4.5% of the sale price.

Counties and cities may add their own sales tax on top of the state rate. So the total rate depends on location. Two towns can have two different total rates.

Which location's rate do you use?

Where the customer gets the goods decides the rate:

• Sold at your place of business: use the rate for your place of business.
• Delivered to the customer: use the rate at the delivery location, where the customer receives the goods.

What is use tax?

Use tax is tax owed on tangible property bought somewhere else and brought into Oklahoma for storage, use, or consumption, when Oklahoma sales tax was not collected on it. If the place where the property is brought in also levies a use tax, that local use tax is owed too.

A note about pennies

The federal government stopped making pennies in November 2025. Pennies are still legal tender, but they are in short supply.

This does not change how you figure Oklahoma sales tax:

• Retailers must still calculate Oklahoma sales tax to the nearest cent, no matter how the customer pays.
• The exact tax shown on the receipt or invoice is the tax that must be remitted.
• For a cash sale, a retailer may round the change to the nearest nickel. That rounding never changes the tax owed — the tax due on a cash sale is the same as on a card sale.

How to get an Oklahoma sales tax permit

If you will sell as a vendor in Oklahoma, you need a sales tax permit from the Oklahoma Tax Commission. The rules are in Oklahoma statute 68 O.S. § 1364.

• Get the permit first. A permit is required before engaging in business as a vendor in Oklahoma. It is unlawful to do business as a vendor without one.
• Cost: the permit costs $20 and lasts 3 years.
• More than one location: each additional business location needs its own permit, at $10 more per location.
• How a new permit starts: a new permit may start with a 6-month probationary period. It then extends automatically for 30 more months, unless the Commission sends written notice that it refuses to renew it.
• The penalty: operating as a vendor without a permit is a misdemeanor, with a fine of up to $1,000.
• How to apply: apply online through OkTAP (the Oklahoma Taxpayer Access Point), or apply by mail with Packet A, the business registration packet.

Display your permit where it can be easily seen at your place of business — the statute requires it to be conspicuously displayed.
