Oklahoma taxes income through 4 graduated brackets in 2026, topping out at 4.5%. The first bracket covers taxable income up to $3,750, and the top rate does not bite until taxable income passes $7,200, which is why the worked example below matters more than the headline rate.

Oklahoma brackets for single filers, 2026
Rates apply to Oklahoma taxable income: gross pay minus the standard deduction and any personal exemption. In Oklahoma the schedule fills from the bottom up: the first $3,750 of taxable income pays 0%, and only the income above each threshold pays the next rate up.
| Taxable income (single) | Rate |
|---|---|
| $0 to $3,750 | 0% |
| $3,751 to $4,900 | 2.5% |
| $4,901 to $7,200 | 3.5% |
| $7,201 and up | 4.5% |
Oklahoma brackets for married filing jointly, 2026
| Taxable income (joint) | Rate |
|---|---|
| $0 to $7,500 | 0% |
| $7,501 to $9,800 | 2.5% |
| $9,801 to $14,400 | 3.5% |
| $14,401 and up | 4.5% |
Standard deduction and exemption in Oklahoma
The 2026 standard deduction is $6,350 for single filers and $12,700 for married filing jointly. Oklahoma also allows a personal exemption of $1,000 for single filers and $2,000 for joint filers, which comes off taxable income alongside the standard deduction. In Oklahoma, that means the first $7,350 of a single filer's pay is taxed at zero before the schedule even starts.
Worked example: the brackets on a $75,000 salary
A single filer earning $75,000 in Oklahoma first removes the standard deduction and personal exemption, leaving $67,650 of taxable income. Each bracket then takes its slice:
| Bracket range | Income in bracket | Rate | Tax |
|---|---|---|---|
| $0 to $3,750 | $3,750 | 0% | $0 |
| $3,751 to $4,900 | $1,150 | 2.5% | $29 |
| $4,901 to $7,200 | $2,300 | 3.5% | $81 |
| $7,201 and up | $60,450 | 4.5% | $2,720 |
Total Oklahoma income tax: $2,830, an effective rate of 3.77% of gross pay. The marginal rate, the rate on the next dollar Oklahoma taxes, is 4.5%; a raise that crosses into that bracket pays 4.5% only on the dollars above the line, never on the whole salary.
Oklahoma income tax on common salaries (single filer)
| Gross salary | Oklahoma income tax | Effective rate | Marginal rate |
|---|---|---|---|
| $40,000 | $1,255 | 3.14% | 4.5% |
| $50,000 | $1,705 | 3.41% | 4.5% |
| $75,000 | $2,830 | 3.77% | 4.5% |
| $100,000 | $3,955 | 3.95% | 4.5% |
| $150,000 | $6,205 | 4.14% | 4.5% |
How Oklahoma compares with other states
How Oklahoma compares: its top rate of 4.5% ranks 28th highest among the 42 taxing jurisdictions for 2026, and the $2,830 owed on a $75,000 salary ranks 21st highest, between Idaho ($2,867) and Arkansas ($2,741).
The shape of the schedule matters as much as the rates. Oklahoma's top rate only starts at taxable income above $7,200, so a $75,000 salary never sniffs it: the highest rate actually touched is 4.5%, and the top slice of the example above contributes $2,720, about 96% of the total bill. The other 4% is spread across the lower 3 brackets.
Joint filers in Oklahoma get thresholds that are exactly double the single ones, so two earners who marry face no bracket penalty on the same combined income. The joint standard deduction of $12,700 is likewise double the single $6,350.
