Oklahoma imposes taxes at both the state and local levels, with a progressive individual income tax and a flat statewide sales tax that is supplemented by local rates.
Understanding how these taxes work can help residents plan more effectively and ensure accurate filing.
Oklahoma Individual Income Tax
Oklahoma uses a graduated (progressive) income tax system, meaning tax rates increase as taxable income rises. Individual income tax rates range from 0.25% to 4.75%.

Upcoming Tax Changes
Legislation enacted in May 2025 will reduce Oklahoma’s top marginal income tax rate to 4.5% and consolidate tax brackets beginning with the 2026 tax year (filed in 2027). Additional rate reductions may occur in future years if state revenue growth meets statutory triggers.
Oklahoma Sales Tax
Oklahoma applies a flat statewide sales tax rate of 4.5%. However, counties and municipalities may levy additional local sales taxes.
