Oklahoma Sales Tax on Services and What Is Taxable: The Enumerated List, Groceries and Software

If you sell something in Oklahoma, the first tax question is rarely whether the sale is a service. The better question is whether it appears on the state's list of taxable transactions. Oklahoma does not tax services as a category, and it does not exempt services as a category either. Under 68 O.S. 1354, the state taxes an enumerated list of sales, and a transaction that is not on that list is generally outside the sales tax. That distinction matters for anyone selling consulting, repairs, software, food or rentals, because two services that look alike can be treated very differently.

This guide explains how the list works, what it covers, and where the rules get less clear. It is a planning resource, not a ruling from the Oklahoma Tax Commission (OTC).

The short answer: Oklahoma taxes a list, not a category

Many states use broad rules such as 'all services are taxable' or 'all services are exempt.' Oklahoma uses neither. The OTC asks whether a transaction falls within one of the enumerated categories. If it does, the 4.5% state rate applies, plus any city and county sales tax collected with it. If it does not, the transaction is not taxed under the list, and you should not add sales tax to the invoice on the strength of the service label alone.

The enumerated list of taxable sales

The following categories are taxable at the 4.5% state rate, plus local tax:

• Tangible personal property (physical goods)
• Utilities other than water, sewage and refuse
• Common-carrier transportation
• Telecommunications
• Printing and copying
• Hotel and motel lodging
• Parking and storage
• Computer hardware and prewritten software, including licenses
• Restaurant food and drink (prepared food remains at the full state rate)
• Advertising
• Club and health-spa dues
• Admissions and recreation
• Vending sales
• Rentals and leases of tangible personal property
• Florist and nursery sales

Notice what is missing. Accounting, legal, consulting and most other professional and personal services are not on the list. A bookkeeper who charges a monthly fee, an attorney who bills for a contract review, or a consultant who bills for strategy work is not making a sale in one of the enumerated categories. Repair and labor charges are the exception to watch. The list does not settle them, so get a specific answer from the OTC before you invoice.

Groceries and food: what changed on August 29, 2024

Since August 29, 2024, the state sales tax does not apply to food and food ingredients, or to certain prepared food. Local sales taxes still apply to those items, so the combined rate on a grocery purchase drops by the state portion but does not disappear. Prepared food, alcoholic beverages and dietary supplements stay at the full state rate. The change came through HB 1955 and SB 1283.

The practical problem is the line between food and prepared food. A packaged grocery item is straightforward. Ready-to-eat items, food prepared on site, and products sold for immediate consumption are where most mistakes happen. If a product sits near that line, confirm its treatment with the OTC before you set your register, and keep sales records detailed enough to show which items were taxed at which rate.

Software and computer hardware

Computer hardware and prewritten software, including licenses, are on the list and are taxable at the state rate plus local tax. That covers a computer you sell and a license fee for an off-the-shelf application. The word that matters is prewritten. Whether custom software built for a single client receives the same treatment is not settled by the list, so confirm it with the OTC before you invoice. If you sell hosted or subscription access to software, also confirm with the OTC how your billing is treated.

Contractors: you are the consumer of your materials

Contractors are the consumers of the materials they install. They pay sales tax on lumber, fixtures, fasteners, wire, pipe and other materials, and they cannot use a sales tax permit to buy those materials tax-free. A sales tax permit lets you collect tax from your own customers on taxable sales. It does not make your purchases exempt.

If you perform work under a contract with an exempt entity, check with the OTC before buying materials. The treatment of contractor purchases under those contracts is not settled by the general list.

Exempt entities and exemption permits

Some organizations do not pay sales tax on their purchases. Churches, schools, universities, municipalities and farmers use an exemption permit to show that status. The federal government, the State of Oklahoma, municipal trust authorities and manufacturers do not qualify in the same way. Do not assume an exemption applies because the buyer is a government body or an industrial business. Confirm eligibility with the OTC before you accept an exemption claim.

Rates, rounding and local tax

The state sales tax rate is 4.5%. The OTC collects city and county sales taxes together with the state tax on one return, so the combined rate runs from about 8.25% to above 10%, depending on where the sale takes place. Confirm the exact rate for your location with the OTC before you set your prices. Tax is computed to the nearest cent.

To collect tax, you need a sales tax permit. The permit costs $20 for three years. Our guide on the Oklahoma sales tax permit walks through the application. You can register through OkTAP at https://oktap.tax.ok.gov/OkTAP/Web?link=BUSREG.

Remote sellers and use tax

Out-of-state sellers face a separate threshold. For remote sellers, the amount that triggers collection is $100,000. The marketplace election is tied to a $10,000 figure, so confirm how that applies to your sales with the OTC.

Use tax is owed on out-of-state purchases used in Oklahoma when Oklahoma sales tax was not charged at the time of purchase. If you buy equipment, supplies or other taxable items from an out-of-state vendor, track those purchases and confirm your filing obligation with the OTC.

Next steps

1. List every product and service you sell, and check each one against the enumerated list above.
2. Separate your sales by treatment: state-exempt food, prepared food at the full rate, other taxable items, and services not on the list.
3. Obtain your sales tax permit through OkTAP before your first taxable sale.
4. Keep copies of exemption certificates and records showing the rate you charged on each sale.
5. For any service, repair or labor charge, request a written answer from the OTC rather than relying on a general rule.
