Oklahoma has seven marginal tax brackets, ranging from 0.50% (the lowest Oklahoma tax bracket) to 5.25% (the highest Oklahoma tax bracket). Each marginal rate only applies to earnings within the applicable marginal tax bracket.

In Oklahoma, different tax brackets are applicable to different filing types. Married couples filing their Oklahoma income tax return jointly will usually have wider tax brackets than those filing separately or as an individual.

You can think of the bracketed income tax as a flat amount for all of the money you earned up to your highest tax bracket, plus a marginal percentage of any amount you earned over that.

What is my Oklahoma tax bracket?

Technically, you don't have just one "tax bracket" - you pay all of the Oklahoma marginal tax rates from the lowest tax bracket to the tax bracket in which you earned your last dollar. For comparison purposes, however, your Oklahoma tax bracket is the tax bracket in which your last earned dollar in any given tax period falls.

Oklahoma Tax Estimator

You can use the income tax estimator to the left to calculate your approximate Oklahoma and Federal income tax based on the most recent tax brackets.

Keep in mind that this estimator assumes all income is from wages, assumes the standard deduction, and does not account for tax credits.

For a more detailed estimate that takes these factors into account, click "View Detailed Estimate" (this will will redirect to an external website).


When calculating your Oklahoma income tax, keep in mind that the Oklahoma state income tax brackets are only applied to your adjusted gross income (AGI) after you have made any qualifying deductions.

Qualifying deductions might include an itemized deduction, the Oklahoma standard deduction, exemptions for dependants, business expenses, etc.

Remember that Oklahoma may have very different deduction laws from the Federal Income Tax, so you may have to write a whole new list of deductions for your Oklahoma income tax return.
