How Oklahoma income tax works

Oklahoma’s 2026 schedule has four bands, but three of them are tiny. Nothing is taxed on the first $3,750, then 2.5% to $4,900 and 3.5% to $7,200 — and 4.5% on everything above $7,200.

Before any of that, a single filer subtracts a $6,350 standard deduction and a $1,000 personal exemption, so $7,350 is sheltered outright.

On $75,000 that leaves $67,650 of Oklahoma taxable income. The three lower bands together account for about $109 of tax; the 4.5% band accounts for the remaining $2,720. Total: roughly $2,830, an effective state rate of about 3.8%.

There is no local income tax anywhere in Oklahoma and no employee-side payroll levy, so these figures need nothing added.

What HB2764 changed

Oklahoma rewrote its income tax for 2026, and the change was structural rather than cosmetic.

The old schedule had six brackets running 0.25% / 0.75% / 1.75% / 2.75% / 3.75% / 4.75%. HB2764 collapsed those into the current four bands and cut the top rate to 4.5%, effective January 1, 2026.

More significant than the rate cut is what else the act did: it established a trigger mechanism that reduces the rate by a further 0.25 percentage point whenever specified revenue conditions are met, with the stated aim of eliminating the individual income tax entirely.

Oklahoma therefore joins Mississippi as a state with a legislated path to zero, though the two work differently. Mississippi’s reductions run on a fixed calendar — 3.75% in 2027, 3.5% in 2028 and so on. Oklahoma’s depend on revenue performance, so the timing is genuinely uncertain even though the direction is not.

Anything quoting Oklahoma’s top rate as 4.75%, or describing six brackets, is describing 2025.

After federal tax, Oklahoma state tax and FICA. With no local income tax and no state payroll levy, these figures hold anywhere in Oklahoma — Oklahoma City, Tulsa, Norman and Broken Arrow alike.

The thresholds do not move

There is a detail in HB2764 worth understanding, because it quietly works against the rate cut.

The new bracket thresholds are fixed dollar amounts and are not indexed for inflation. The top band begins at $7,200 of taxable income — a figure that almost every full-time worker in the state already clears several times over.

So Oklahoma’s four-band schedule is progressive only across a very narrow range. In practice it behaves as a flat 4.5% tax with a small fixed discount on the first $7,200, much as Virginia behaves as a flat 5.75% state because its top band starts at $17,000.

As wages rise with inflation, the untaxed $3,750 band and the two low bands shelter a steadily smaller share of income, so the effective rate creeps upward even with the headline rate falling. Unless the legislature indexes the thresholds or the revenue triggers keep firing, that drift offsets part of the cut over time.

The standard deduction of $6,350 is likewise fixed rather than indexed, and the same logic applies to it.

Dates that matter for the 2026 tax year

Oklahoma returns (Form 511) are due April 15, 2027, matching the federal deadline. Oklahoma grants an extension where a federal extension is in place, though tax owed remains due in April. Estimated payments, if required, fall quarterly in April, June, September and the following January.

Questions people ask

What is the Oklahoma income tax rate for 2026?

Four bands after HB2764: nothing on the first $3,750 of taxable income, 2.5% to $4,900, 3.5% to $7,200, and 4.5% above that. The top rate was cut from 4.75%.

What changed in Oklahoma tax for 2026?

HB2764 collapsed six brackets into the current schedule and reduced the top rate. It also created a trigger mechanism that cuts the rate a further 0.25 percentage point at a time when revenue conditions are met, aiming eventually at eliminating the individual income tax.

What can I deduct in Oklahoma?

A standard deduction of $6,350 for a single filer or $12,700 filing jointly, plus a personal exemption of $1,000 per filer. Those stack, so a single filer shelters $7,350 before the untaxed $3,750 band is even reached.

Are the Oklahoma brackets adjusted for inflation?

No. The thresholds set by HB2764 are fixed dollar amounts and are not indexed. Since the top band begins at just $7,200 of taxable income, almost every full-time worker already pays 4.5% on the bulk of their income, and that will only become more true as wages rise.

Does any Oklahoma city charge a local income tax?

No. No Oklahoma city or county levies an income tax, so where you live in the state does not change your income tax bill.

Are Oklahoma payroll deductions taken from my paycheck?

Not by the state. Oklahoma unemployment insurance is employer-funded and the state runs no disability or paid family leave program. Beyond the state income tax, the only deductions are federal.
