Oklahoma has state income tax, so wage earners should account for Oklahoma tax along with federal income tax, Social Security, Medicare, deductions, benefits, credits, and withholding choices.
This page brings the Oklahoma tax picture together in one place: state tax data, Oklahoma deductions and adjustments, local tax treatment, and the combined federal, state, and FICA rate you actually face on your income.
Oklahoma state income tax brackets
| Tax Rate | Single | Married (Joint) | Married (Separate) | Head of Household |
|---|---|---|---|---|
| 2.5% | Up to $4,900 | Up to $9,800 | Up to $4,900 | Up to $9,800 |
| 3.5% | $4,900 – $7,200 | $9,800 – $12,200 | $4,900 – $7,200 | $9,800 – $12,200 |
| 4.5% | Over $7,200 | Over $12,200 | Over $7,200 | Over $12,200 |
Brackets apply to Oklahoma taxable income — income after deductions and exemptions, not your gross salary. The U.S. system is progressive: each rate applies only to the income inside its own bracket, never to your whole income.
The table above shows the current Oklahoma state income tax treatment for each filing status.
Oklahoma deductions and adjustments
| Filing Status | Standard Deduction | Personal Exemption |
|---|---|---|
| Single | $6,350 | $1,000 |
| Married Filing Jointly | $12,700 | $2,000 |
| Married Filing Separately | $6,350 | $1,000 |
| Head of Household | $9,350 | $1,000 |
These amounts are subtracted from income before Oklahoma's tax rates apply. They are separate from — and in addition to — the federal standard deduction.
The table above shows the Oklahoma deduction and adjustment rules stored in the PaycheckNet database.
Oklahoma local income taxes
Oklahoma does not generally have a broad local wage income tax system. Local sales, property, or other taxes may still apply separately.

Marginal rate = the tax on your NEXT dollar of gross income. Because the federal government and Oklahoma each subtract their own deductions before applying brackets, the ranges here are expressed in gross income — the two bracket tables cannot simply be added together.
FICA is the employee share of Social Security and Medicare. It applies from the first dollar, stops on wages above the Social Security cap, and rises again where the Additional Medicare surtax begins.
| Gross Income | Federal Tax | Oklahoma Tax | FICA | Total Tax | Take-Home Pay | Effective Rate |
|---|---|---|---|---|---|---|
| $30,000 | $1,420 | $898 | $2,295 | $4,613 | $25,387 | 15.4% |
| $50,000 | $3,820 | $1,798 | $3,825 | $9,443 | $40,557 | 18.9% |
| $75,000 | $7,670 | $2,923 | $5,738 | $16,331 | $58,669 | 21.8% |
| $100,000 | $13,170 | $4,048 | $7,650 | $24,868 | $75,132 | 24.9% |
| $150,000 | $24,734 | $6,298 | $11,475 | $42,507 | $107,493 | 28.3% |
| $200,000 | $36,734 | $8,548 | $14,339 | $59,621 | $140,379 | 29.8% |
| $300,000 | $68,134 | $13,048 | $16,689 | $97,872 | $202,129 | 32.6% |
| $500,000 | $138,134 | $22,048 | $21,389 | $181,572 | $318,429 | 36.3% |
Effective rate = total tax as a share of gross income. It is always lower than your top marginal rate, because only the last slice of income is taxed at the highest bracket.
The combined table shows what an Oklahoma resident pays once federal tax, Oklahoma state tax, and FICA are stacked together.
Social Security and Medicare
| Employee Rate | Wage Limit | |
|---|---|---|
| Social Security | 6.2% | First $184,500 of wages |
| Medicare | 1.45% | All wages (no cap) |
| Additional Medicare | 0.9% | Wages above $200,000 (single / head of household), $250,000 (married filing jointly), $125,000 (married filing separately) |
FICA comes out of every paycheck in every state and is separate from income tax. Employers pay a matching share on top of these employee rates; self-employed workers pay both halves through self-employment tax.
FICA applies the same way in Oklahoma as it does across the rest of the country.
