How to Use This Calculator
Enter your income, filing status, and any deductions. The calculator computes your Oklahoma state income tax alongside your federal tax, showing exactly how much goes to each and what you take home.
The most useful thing to try? Compare different income levels to see how Oklahoma's brackets affect your tax bill, then look at how combined federal + state taxes shape your total take-home pay.
Here's what each field means:
Annual Income is your total earnings before any taxes. Include wages, freelance income, investment income, and any other sources.
Filing Status determines which set of tax brackets and deductions apply. Oklahoma uses filing statuses similar to the federal system — single, married filing jointly, married filing separately, and head of household.
Oklahoma Income Tax: What You Need to Know
Oklahoma uses a progressive income tax system with rates ranging from 0.25% to 4.75%. Like the federal system, this means your income is taxed in layers — each bracket only applies to the income within that range, not your entire income.

A Real Example
Let's say you're a single filer earning $60,000 in Oklahoma. After applying the standard deduction of $6,350, your income flows through each bracket:
Your approximate Oklahoma state income tax would be around $2,459, for an effective state tax rate of about 4.1%.
Remember, this is just the state portion. You'll also owe federal income tax and FICA taxes on top of this.
Deductions and Exemptions
Standard Deduction: Oklahoma offers a standard deduction of $6,350 for single filers and $12,700 for married couples filing jointly.
Oklahoma standard deduction, personal exemption of $1,000, retirement income exclusion up to $10,000, 529 plan deduction up to $20,000 per year.

What's Unique About Oklahoma
Oklahoma has six brackets, but you hit the top 4.75% rate at just $7,200 of taxable income (single), which means the brackets are largely cosmetic for most workers. Oklahoma uses its own standard deduction and personal exemption ($1,000 per person). The state does not tax Social Security benefits and offers a retirement income exclusion of up to $10,000 for those with qualifying income. Oklahoma also allows a deduction for contributions to Oklahoma 529 college savings plans.
Recent Changes
Oklahoma has been discussing further rate cuts. The 4.75% top rate has been stable, but there's legislative interest in moving to a flat tax or further reducing rates.
