Income tax in Oklahoma
Oklahoma taxes wage income on a progressive schedule — 3 brackets running from 2.5% to 4.5% for single filers. This calculator applies Oklahoma's real 2026 brackets, its standard deduction ($7,350 single / $14,700 married) and its personal exemption, so the state-tax line follows the actual schedule rather than a flat-rate guess.
Oklahoma income tax brackets for 2026
Single filers. Each rate applies only to the income falling inside that band — these are marginal rates, not a flat rate on the whole salary.
| Taxable income over | Rate |
|---|---|
| $3,750 | 2.5% |
| $4,900 | 3.5% |
| $7,200 | 4.5% |
State taxable income is your pay after Oklahoma's standard deduction and personal exemption of $7,350 for a single filer ($14,700 married filing jointly).
How Oklahoma compares
A single filer earning $100,000 pays $3,954 in Oklahoma state income tax — 23rd of 51, in the upper-middle of the pack. Connecticut ($3,925), Wisconsin ($3,919) and Michigan ($3,999) land within a few hundred dollars either way. The headline 4.5% rate is a marginal rate, so it applies to your last dollar, not your whole salary.
Worked example: $100,000 in Oklahoma
Take a single filer on $100,000 in Oklahoma. After the $7,350 standard deduction and personal exemption, state taxable income is $92,650:
| Income band | Rate | Tax |
|---|---|---|
| $3,750 – $4,900 | 2.5% | $29 |
| $4,900 – $7,200 | 3.5% | $81 |
| $7,200 – $92,650 | 4.5% | $3,845 |
| Total state tax | — | $3,954 |
The effective rate works out to 4.0% of gross salary — far below the 4.5% top marginal rate, because only the last slice of income is taxed at that rate.
