Oklahoma combines low income taxes with high sales taxes. Corporations pay a flat 4%, the personal top rate falls to 4.5% in 2026 and the franchise tax is gone. The state sales tax is only 4.5%, but local add-ons push the average combined rate above 9%. Energy, aerospace and agriculture anchor the economy, and the state offers generous incentives to manufacturers and employers.
This guide covers Oklahoma's business taxes for 2026, with worked examples and comparisons with its six neighbors.
Oklahoma business taxes at a glance
An Oklahoma C corporation pays a flat 4% on profit and no longer pays franchise tax. Pass-through owners pay graduated rates that reach 4.5% above $7,200 of taxable income, so most business profit is taxed at 4.5%. Customers pay sales taxes that average more than 9%, among the highest in the country, because cities rely heavily on sales tax. LLCs pay $100 to form and $25 a year. Property taxes are low, and manufacturers can receive five-year property tax exemptions on new facilities.

How Oklahoma compares with its neighbors
Oklahoma's 4% corporate rate ties Missouri's for the lowest among its neighbors with a corporate income tax. Texas has no personal income tax, which matters for businesses near the Red River and in the Dallas-Fort Worth orbit. Oklahoma's combined sales tax rate is higher than most neighbors', however.
Choosing an entity in Oklahoma
- LLC: $100 to form, $25 a year and pass-through treatment at up to 4.5%.
- S corporation: Same personal rate, with federal payroll tax savings.
- C corporation: 4% state tax plus 21% federally, and no franchise tax since 2024.
Doing business across Oklahoma
Oklahoma City and Tulsa are the state's two main business centers. Oklahoma City is home to state government, Tinker Air Force Base and much of the energy industry, while Tulsa has a strong aerospace, manufacturing and energy services base and has attracted remote workers with incentive programs. Sales tax rates differ significantly between cities, so retailers selling into multiple jurisdictions need accurate rate tables. Tribal jurisdiction also affects taxes in parts of eastern Oklahoma: since the 2020 Supreme Court decision in McGirt v. Oklahoma, some tribal members living and working within reservation boundaries are exempt from state income tax, and businesses operating on tribal land may face different rules.
Tax planning tips for Oklahoma businesses
Apply for the Quality Jobs Program. Qualifying employers can receive quarterly cash payments of up to 5% of new payroll for up to ten years. Apply before creating the jobs.
Use the manufacturer's exemption permit. Manufacturers can buy machinery, equipment and raw materials without paying sales tax, a major saving given Oklahoma's high combined rates.
Seek the five-year property tax exemption. New or expanding manufacturing facilities can be exempt from property tax for five years if they meet investment and payroll thresholds.
Who pays the most in Oklahoma
Oklahoma's tax system relies heavily on sales tax and energy production taxes, so consumers, retailers and oil and gas producers carry much of the burden. Cities fund most of their services from sales tax, which is why combined rates in places like Tulsa and Oklahoma City exceed 8.5%. The gross production tax on oil and gas is 7% for established wells and 5% for new wells during their first three years. Pass-through owners pay a moderate 4.5%, and C corporations pay one of the lowest corporate rates in the country. Small businesses that don't sell taxable goods face relatively light state taxes.
Entity choice examples in Oklahoma
Consider a consulting firm with $200,000 of annual profit. As a single-member LLC, the owner pays about $8,785 of Oklahoma tax, plus federal income and self-employment tax. As an S corporation paying the owner a reasonable salary of $100,000, the state tax is about the same, but federal payroll taxes on the remaining $100,000 of distributions are avoided. As a C corporation, the business pays $8,000 of Oklahoma tax at 4%, but any dividends paid out are taxed again at the owner's personal rate. For most owner-operated businesses that distribute their profits, an LLC taxed as an S corporation is the most efficient choice.
