Oklahoma's 2026 state standard deduction is an estimated $6,350 for single filers, $12,700 for married couples filing jointly, and $9,350 for heads of household. The standard deduction lowers the income Oklahoma taxes, so you only pay state tax on income above these amounts unless itemizing produces a larger deduction.
| Filing status | Standard deduction |
|---|---|
| Single | $6,350 |
| Married filing jointly | $12,700 |
| Head of household | $9,350 |
Your Oklahoma standard deduction is subtracted from your state taxable income before the tax rate is applied. You take either the standard deduction or your total itemized deductions — whichever is larger. Most households take the standard deduction because it exceeds their itemizable expenses.
