What are Oklahoma's income tax brackets?

Oklahoma uses six graduated brackets for single filers from 0.25% up to a top rate of 4.75% on taxable income above about 7,200 dollars. Married-filing-jointly brackets are double the single thresholds.

What is the Oklahoma standard deduction?

Oklahoma's standard deduction is 6,350 dollars for single filers and 12,700 dollars for married filing jointly, mirroring older federal amounts. Head of household filers get 9,350 dollars.

Does Oklahoma have a personal exemption?

Yes. Oklahoma allows a personal exemption of 1,000 dollars per person, including yourself, your spouse, and dependents, which reduces your taxable income before the brackets are applied.

What is the effective tax rate?

The effective rate is total tax divided by gross income. Because of the standard deduction, exemptions, and graduated brackets, your effective rate is always lower than your top (marginal) bracket rate.

Does this calculate federal tax too?

Oklahoma’s income tax tops out at just 4.75%, but the exact amount you owe depends on your filing status, the standard deduction, and personal exemptions. This calculator applies Oklahoma’s graduated brackets to your taxable income and shows your total state tax, marginal bracket, and effective rate.

How it works

Oklahoma income tax is computed in three steps:

Subtract deductions. From gross income, subtract Oklahoma’s standard deduction ($6,350 single, $12,700 married) and $1,000 per personal exemption to get taxable income.
Apply the graduated brackets. Oklahoma taxes each band of taxable income at its own rate, from 0.25% up to a top rate of 4.75% above $7,200 (single; doubled for married filing jointly).
Sum the tax. Each band’s tax is added together — only the income within a higher band is taxed at the higher rate.

Tax = progressive(gross − std deduction − exemptions, OK brackets)

Tips and example

A single filer with $50,000 of gross income subtracts the $6,350 standard deduction and one $1,000 exemption, leaving $42,650 taxable. Almost all of that falls in the top 4.75% band, so the tax is roughly $1,900 — an effective rate under 4% thanks to the lower bands and deductions.

Adding dependents increases your exemptions and lowers taxable income. Because Oklahoma’s top bracket starts so low, most middle-income filers pay close to the 4.75% marginal rate on the bulk of their income.
