Oklahoma simplified its income tax for 2026: three rates, 2.5%, 3.5%, 4.5%, replacing six brackets that topped out at 4.75%. Withholding is based on your Oklahoma OK-W-4, where each allowance is worth $1,000 a year, and is rounded to the nearest dollar.

2026 tax year, rules last verified November 12, 2026. An estimate, not tax advice. How we calculate
Each extra dollar you earn loses about 24¢ to taxes, but across all your pay the average is 20¢. A raise never lowers your take-home: only the dollars above a bracket line pay the higher rate.
| Annual pay | Effective | Marginal |
|---|---|---|
| $15,000 | 8.5% | 12.2% |
| $30,000 | 15.1% | 24.1% |
| $45,000 | 18.1% | 24.1% |
| $60,000 | 19.6% | 24.1% |
| $75,000 | 21.6% | 34.2% |
| $90,000 | 23.7% | 34.2% |
| $105,000 | 25.2% | 34.2% |
| $120,000 | 26.3% | 34.2% |
| $135,000 | 27.4% | 36.1% |
| $150,000 | 28.3% | 36.1% |
Same pay, W-4 and benefits; each state’s default withholding answers, no local taxes. Take-home per week:
Oklahoma’s OW-2 percentage formula subtracts your allowances (count × the per-period value) from this paycheck’s wages, then applies the single or married table for your pay period. The result is rounded to the nearest dollar.
On the annual single table, the first $10,100 after allowances is tax-free, the next $1,150 is withheld at 2.5%, the next $2,300 at 3.5%, and everything above $13,550 at 4.5%. In practice most full-time workers are in the 4.5% bracket.
Oklahoma follows federal taxable wages, so 401(k) deferrals and pre-tax health premiums reduce it.
| Rate | Single (incl. head of household) | Married |
|---|---|---|
| 0% | up to $10,100 | up to $20,200 |
| 2.5% | $10,100–$11,250 | $20,200–$22,500 |
| 3.5% | $11,250–$13,550 | $22,500–$27,100 |
| 4.5% | over $13,550 | over $27,100 |
Subtract $1,000 per allowance first. Per-paycheck tables use the same rates with thresholds per pay period.

Married filing jointly with two children on $100,000: $1,649.67 a week ($85,783 a year).
None. No Oklahoma city or county taxes wages, including Oklahoma City and Tulsa.
Oklahoma has no state disability, paid family leave or employee unemployment deduction. Unemployment insurance is paid by employers.
Oklahoma has no reciprocal agreements. Residents working in another state claim a credit on their Oklahoma return for tax paid there.
Single with 1 allowance: $34. Married with 2 allowances: $24.
The rates fell to 2.5%, 3.5%, 4.5% with a larger tax-free band, so most paychecks have a little less Oklahoma tax withheld than in 2025.
Your employer can withhold at the year’s top rate, 4.5%, on a bonus paid separately, or add the bonus to your regular wages and use the normal tables.
If only one spouse works, yes. If both work, “Married, but withhold at higher Single rate” on the OK-W-4 usually gets closer to what you will owe.
