Rank 1 is the lowest state income tax burden of the 51 jurisdictions modelled, rank 51 the highest, and states taking the same amount share a rank. The table shows the states immediately around Oklahoma plus its position against the two extremes; the full ranking of all 51 is on the comparison index.
Oklahoma's position at other salary levels, on the same ranking: $50,000: 52nd, $2,375 · $150,000: 15th, $7,125 · $200,000: 10th, $9,500. A state can be cheap at one income and ordinary at another, because graduated brackets bite only above their thresholds — which is why the ranking on this page is quoted at a stated salary rather than as a permanent verdict.

How Oklahoma taxes income
Oklahoma taxes wage income, so the numbers on this page carry a state layer on top of the federal one. The state layer depends on how the income is split across Oklahoma's own brackets, which is why the same salary costs a different amount here than in a flat-rate state: the effective state rate of 4.75% at $100,000 is an average across every slice of pay, while the next slice of income is charged at about 4.8%.
Two rates matter and they are not the same number. The effective rate of 4.75% is what the state layer costs across the whole salary; the marginal rate in Oklahoma is about 4.8% — always the higher of the two when a state levies tax, because the lower slices have already been taxed more cheaply. A raise is priced at the marginal rate, not the average one.
Figures on this page cover the 2026 and 2027 tax years and come from the same calculation engine as the calculator itself, so the comparison here and the take-home figure on Oklahoma's own pages cannot drift apart.
