Oklahoma charges 0.25-4.75% state income tax. Use the quarterly tax estimator pre-loaded with Oklahoma rates.
Open Quarterly Tax Estimator →Quarterly estimated payments in Oklahoma must cover both your federal and state obligations. Oklahoma uses graduated rates (0.25-4.75%), and most states require their own quarterly payment schedule that may differ from the IRS dates. This estimator pre-loads Oklahoma's tax rates so you can calculate both federal and state quarterly amounts in one place, avoiding underpayment penalties at both levels.
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.
