Oklahoma charges 0.25-4.75% state income tax. Use the tax refund estimator pre-loaded with Oklahoma rates.
Open Tax Refund Estimator →In Oklahoma, you may receive refunds at both the federal and state level. Your state refund depends on how your employer's graduated withholding compared to your actual Oklahoma tax liability. Common reasons for a state refund include credits, deductions, or withholding calibrated for a higher income than you actually earned. Use this estimator to project both your federal and Oklahoma state refund amounts.
Oklahoma uses a graduated income tax with brackets ranging from 0.25-4.75%. Lower income is taxed at lower rates, with the 4.75% top rate applying only to income in the highest bracket. This progressive structure means your effective state tax rate is always lower than the top marginal rate. Oklahoma does not have local income taxes, so the state graduated rate is the total state-level income tax burden.
