Taxes and Incentives
Sales Tax Exemptions
(68 O.S. §§ 1359, 1359.2 and 1364)
Oklahoma has a comprehensive sales tax exemption for manufacturers who obtain a Manufacturer’s Sales Tax Exemption Permit from the Oklahoma Tax Commission. The permit must be renewed every three years. This permit must be presented to the vendor, and a claim for exemption made at or before the time of purchase, to relieve the vendor of the liability for collecting sales tax. The exemptions cover purchases of machinery and equipment, energy, and tangible personal property used in design, development, and manufacturing.
Sales to a manufacturer of exempt property must be used in the manufacturing operation at a manufacturing site. The exemption is not extended to purchases for administration, sales, distribution, transportation, site construction or site maintenance.
For more information and certification, contact the Oklahoma Tax Commission at 405-521-3133 or email@example.com.
Computer Services And Data Processing
(68 O.S. § 1357 )
Oklahoma recognizes the importance of companies engaged in computer services or data processing activities by offering exemptions from sales tax on:
Sales of machinery and equipment purchased and used by persons and establishments primarily engaged in computer services and data processing:
- As defined under Industrial Group Numbers 7372 and 7373 of the Standard Industrial Classification (SIC) Manual, latest version, which derive at least fifty percent (50%) of their annual gross revenues from the sale of a product or service to an out-of-state buyer or consumer; and
- As defined under Industrial Group Number 7374 of the SIC Manual, latest version, which derive at least eighty percent (80%) of their annual gross revenues from the sale of a product or service to an out-of-state buyer or consumer.
Eligibility for the exemption set out in this paragraph shall be established, subject to review by the Tax Commission, by annually filing an affidavit with the Tax Commission stating that the facility so qualifies and such information as required by the Tax Commission. For purposes of determining whether annual gross revenues are derived from sales to out-of-state buyers or consumers, all sales to the federal government shall be considered to be to an out-of-state buyer or consumer.

Excise Tax On Aircraft Sales
(68 O.S. § 6001)
HB 2253-Effective May 10, 2018
Oklahoma House Bill 2253 HB 2253 modifies the aircraft excise tax exemption afforded aircraft purchased or used by commercial airlines, specifically charter aircraft (aircraft operating under Part 135 of Title 14 of the Code of Federal Regulations). In order to qualify for this exemption, the aircraft owner cannot operate under Part 91 of Title 14 of the C.F.R. for more than fifty percent (50%) of its annual operations. If the operations of such aircraft are not at least fifty percent (50%) Part 135 charter operations annually, the aircraft excise tax levied shall be due and payable.
An aircraft owner must provide a report to the Oklahoma Tax Commission on an annual basis detailing the operations of the aircraft and any supporting flight, maintenance or charter log books required by the Commission. For the purpose of satisfying this requirement, such operations may not include those chartered by the aircraft owner as an individual or as a business entity in which the aircraft owner owns a majority interest.
(68 O.S. §§ 1354 and 1357  )
Sales tax exemptions apply to Interstate 1-800, WATS, and interstate private-line business telecommunication services, and to cell phones sold to a vendor who transfers the equipment as part of an inducement to a consumer to contract for wireless telecommunications.
(68 O.S. § 1356) [32 - 37]
Sales of any tangible property to a spaceport user as determined by the Oklahoma Space Industry Development Authority are exempt from sales tax. Launch vehicles, satellites and such related attached or used property may also be purchased free from sales and use tax.
Sales Tax Refunds
Oklahoma offers sales tax refunds for qualified companies. To qualify, a company must submit an Application/Intent to Qualify to the Oklahoma Tax Commission to establish an interest-bearing account. Upon receiving the application and documentation concerning the sales/use taxes to be paid by the applicant or their contractors, the Oklahoma Tax Commission will determine whether a company qualifies. If so, the Oklahoma Tax Commission will immediately set up an account to track sales taxes paid on sales as shown by the invoices submitted.
For purposes of the exemption at section 1359 (7) of Title 68 for qualified manufacturers, interest is determined according to the amount earned as invested by the State Treasurer's Office. For the remaining refunds at Sections 1357(17) and 54003 of Title 68, interest accrues at the rate of a 3-month Treasury bill from the date invoiced items are approved.
Sales taxes paid on construction materials incorporated in certain new manufacturing facilities by the manufacturer or by a contractor or subcontractor on behalf of a qualified manufacturer are refundable.
Sales taxes paid for machinery and equipment by certain service businesses (computer services, R & D, and aircraft repair) are refundable. Invoices of each vendor that distinguish the state and local sales taxes paid must be submitted with claims.
Affidavits from vendors or contractors that the sales taxes were charged, paid, and have not been refunded by the vendor must be submitted with claims. Eligible applicants must file for a refund within 36 months of the date of purchase. The Oklahoma Tax Commission requires certification from the Oklahoma Employment Security Commission regarding the number of jobs.
Note: Participation In The Quality Jobs Program Or Other Incentive Payment Programs Precludes Participation In These Refunds.
Computer Services / Data Processing / Telecommunications Equipment
(68 O.S. § 54003)
Oklahoma offers a sales tax refund on the purchase of computers, data processing equipment, related peripherals, telegraph or telecommunications services, and equipment.
- Applies to NAICS Nos. 51121, 336411, 541512, 518210 and 518111 (Computer services and data processing) and 541712, 541720, 541712 and 541380 (Research and Development).

- These new employees must be employed for at least 36 months.
- 50% of annual gross revenues must result from sales to out-of-state buyers but may include the federal government.
- 75% of annual gross income results from computer services, data processing activities, or research and development activities.
- If the company is in 518210, it must also purchase $100,000 worth of exempt items.
Note: This Refund Is Not As Favorable To Computer Services And Data Processing Companies As The Sales Tax Exemption Found At 68 0.S. § 1357 (21).
(68 O.S. § 1359 )
Oklahoma refunds sales taxes paid on construction materials for certain new or expanding manufacturing facilities including:
- Facilities with construction costs exceeding $5 million which create 100 new manufacturing jobs and are maintained for a minimum of 36 months. Construction costs include building and construction costs, and engineering and architectural fees, but not legal fees.
- Facilities with construction costs exceeding $10 million, and with combined total costs of material, construction, and machinery exceeding $50 million, which add 75 new employees who are retained for 36 months.
- Facilities with construction costs exceeding Three Hundred Million Dollars ($300,000,000) which maintain an employment level of a least 1,750 full time equivalent employees.
- Qualified new or expanding aircraft maintenance and overhaul facilities that create 250 or more jobs, with construction costs totaling at least $5 million. [68 O.S. 1357(17)].
These construction exemptions are unique not only because they are refunds, but also because they allow contractors or subcontractors that have previously entered into a written contractual relationship with the manufacturer, or a qualified aircraft maintenance facility operator, to make refundable purchases on behalf of manufacturers. The manufacturer may use invoices made out in the contractors’ names for proof when applying for sales tax refunds. Generally, refundable purchases do not include machinery and equipment. Warehousing/Distribution for manufacturers, structures, or land used for packaging, re-packaging, labeling, or assembly for distributing products that are at least 70% made in Oklahoma, but at an off-site, in-state manufacturing facility or facilities are also deemed manufacturing facilities for purposes of these sales tax refunds.
