Oklahoma's income tax is graduated: 6 brackets running from 0.25% to 4.75%, the 25th-highest top rate of the 51 jurisdictions. The top rate applies to a single filer's taxable income above $7,200. Because that top bracket starts so low, Oklahoma behaves like a flat 4.75% tax for most full-time earners — the graduated part only shapes the first few thousand dollars. Joint filers get exactly double the bracket widths at every rate, so a married couple pays what two single filers on half the income each would pay. Heads of household get a third schedule of their own, wider than the single one. A single filer subtracts a $6,350 standard deduction and a $1,000 personal exemption before the rates are applied.

Assumptions
- Ordinary-income rate schedules only; no credits, AMT, capital-gains rates, QBI deduction or the 2025–2028 senior deduction.
- Standard deduction (plus additional amounts for 65+/blind) or your itemized figure, whichever is larger; no dependent-filer limitation.
- Married filing separately uses half the joint federal thresholds, per the IRS schedule, and the state's single-filer schedule.
- State tax uses each state's published rate schedule, standard deduction and personal exemption for the tax year shown with the results; the source URL and year for the state you pick are printed above the results, along with the simplifications made for that state.
- State figures exclude county, municipal and city income taxes, itemized deductions, retirement and capital-gains exclusions, and credits that phase out. Unlisted states fall back to the flat rate you enter.
| Taxable income | Rate | Your income in this bracket | Tax |

| $0 – $12,400 | 10% | $12,400 | $1,240 |

How the neighbours compare
Oklahoma borders 6 other jurisdictions. Moving across a state line is the one way most people can actually change which of these schedules applies to them, so here is the same income run through each of them.
| State | Rate structure | $50,000 | $75,000 | $150,000 |
|---|---|---|---|---|
| Oklahoma | 0.25% – 4.75% | $1,837 | $3,025 | $6,587 |
| Arkansas | 0% – 3.9% | $1,405 | $2,380 | $5,305 |

State income tax on a single filer, after each state’s own deductions. Federal tax is identical wherever you live, so the difference between these rows is the whole difference.
What these Oklahoma figures leave out
Recorded against Oklahoma in the data rather than glossed over, because they change real bills.
- Oklahoma had not published a 2026 rate schedule when this was compiled. House Bill 2764 collapses these six brackets into three and cuts the top rate to 4.5% from 1 January 2026, so 2026 tax will be lower than shown — this state needs review before it is relied on for 2026.
- Heads of household use the same schedule as joint filers, which is applied here.
