Oklahoma Paycheck Calculator & Income Tax Rates (2026)

Oklahoma applies 6 rates to taxable income — that is, income after the state standard deduction or exemption. Only the slice of income inside each band is taxed at that band's rate.

Oklahoma's effective state rate climbs with income as more of your salary lands in higher bands. The last column shows the state rate on your next dollar at each level.

Oklahoma's joint brackets widen the bands for couples, so the same household income is taxed more lightly. On $100,000 a joint return keeps $81,106 versus $75,081 for a single filer.

Oklahoma's individual income tax tops out at 4.5% for 2026, down from 4.75%, under HB 2764, signed in May 2025. The law also compressed the six-bracket schedule into three and wrote a path to zero: whenever state revenue growth clears a set threshold, the top rate drops another quarter point, a trigger that can repeat until the tax disappears. The cut continues a run that took the top rate from 5.25% in 2021 to 4.75% in 2022. In practice Oklahoma has long been a flat tax wearing graduated clothes—the top bracket begins at only a few thousand dollars of taxable income, so a full-time worker pays 4.5% on nearly everything above the standard deduction. The tax starts from federal adjusted gross income with Oklahoma adjustments. Where Oklahoma diverges from its neighbors is the mix: a low income tax and low property taxes paired with combined sales taxes near 9% that still fall on groceries at the local level.

The standard deduction is $6,350 for single filers and $12,700 for joint filers, fixed since 2017, plus a $1,000 personal exemption per person. Itemizing requires itemizing federally, and itemized deductions other than charity and medical are capped at $17,000. Credits include an earned income credit at 5% of the federal amount, a child credit at 5% of the federal credit below $100,000 of income, and the Parental Choice Tax Credit of $5,000 to $7,500 per child for private school tuition.

No Oklahoma city, county or school district levies an income or wage tax. Because the constitution bars municipalities from using property tax for day-to-day operations, Oklahoma City and Tulsa run almost entirely on sales tax, which is why local sales tax rates here are among the nation's highest instead.

The state sales tax is 4.5%, but Oklahoma cities cannot levy property tax for general operations under the state constitution, so they lean on sales tax instead: Oklahoma City's local rate is 4.125% for a combined 8.625%, Tulsa's total is 8.517%, and the statewide average of about 8.9% is among the highest in the country. The state stopped taxing groceries on August 29, 2024, but city and county rates still apply to food. Prescription drugs are exempt.

Oklahoma's property taxes are low, with effective rates around 0.85% to 0.9% of market value and a median bill near $1,500. Homes are assessed at 11% to 13.5% of market value depending on the county, a homestead exemption removes $1,000 of assessed value, and a constitutional cap keeps a homestead's taxable value from rising more than 3% a year. Homeowners 65 and older with household income below their county's median can freeze taxable value permanently, one of the region's more generous senior freezes.

Social Security is fully exempt, and so is military retirement pay, which Oklahoma stopped taxing entirely in 2022 after years of a 75% exclusion. Other retirement income gets the $10,000 retirement income exclusion: each taxpayer can exclude up to $10,000 of pension, annuity, 401(k) and IRA distributions—$20,000 for a couple—whether the source is a private employer, the federal civil service or an Oklahoma public retirement system. Everything above that is taxed at the regular rates, which means 4.5% on almost all of it. The exclusion is not indexed and has sat at $10,000 since 2007, so it shelters a smaller share of retirement income each year. Railroad Retirement benefits are exempt.

Oklahoma is effectively a 4.5% flat tax, and the winners pair that with cheap housing: a $200,000 family pays about 4% effective, nothing local, and roughly $2,000 in property tax on a $250,000 home. Retirees do well—Social Security and military pensions exempt, $10,000 per person sheltered, a senior valuation freeze—though large IRA withdrawals pay 4.5% past the exclusion. Married couples pay no penalty; joint brackets are double. The losers are low-income households facing nearly 9% combined sales tax on groceries at the local level, which a small standard deduction and 5% earned income credit barely offset.

The median household income in Oklahoma is $51,000, which is $41,320 a year ($3,443 a month) after all taxes. That is close to the national median. After adjusting for cost of living, the purchasing power of that take-home is equivalent to $47,494 in an average-cost area.

Oklahoma ranks #27 of 50 for raw take-home pay and #5 for cost-adjusted purchasing power at $100,000. The 22-place gap between the two reflects a below-average cost of living that boosts real purchasing power. The best state (Alaska) leaves $79,125; the worst (Oregon) leaves $70,932. Oklahoma is $4,044 behind the leader.
