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.
