How much you owe depends on your taxable income, filing status, and eligibility for deductions or credits. Oklahoma residents pay income taxes on income earned statewide, while nonresidents are taxed on income sourced from Oklahoma. Part-year residents are taxed on income earned while a resident of the state and any state sourced income earned while a nonresident. Understanding these details is important for managing your state taxes efficiently for the 2024 tax year (the taxes you’ll file in 2025). *Note that you are still responsible for federal taxes if you meet the IRS income filing threshold.

Filing Oklahoma state income taxes depends on your residency status and source of income. Specific income thresholds determine your obligation to file, whether you’re a resident, part-year resident, or nonresident. Here’s a quick breakdown: Residents: If your gross income (from all sources) exceeds the Oklahoma standard deduction plus personal exemption, you’re required to file a state income tax return. Even if you’re not required to file a federal return, you must attach a completed federal return to your Oklahoma return if your gross income is more than your adjusted gross income (AGI). If you don’t meet the filing requirements but had Oklahoma tax withheld, made estimated tax payments, or qualify for refundable credits (e.g., Natural Disaster Tax Credit), you could file a return to claim your refund. Part-year residents: You must file as a resident for your period in Oklahoma. For the period you were a nonresident, filing is required if you have gross income of $1,000 or more from Oklahoma sources. Nonresidents: Nonresidents with gross income of $1,000 or more from Oklahoma sources must file a state income tax return, with some exceptions under the Pass-Through Entity Act of 2019. You must file an Oklahoma state income tax return if your Oklahoma-derived gross income exceeds the thresholds listed below for your filing status: Filing status Gross income threshold Single $7,350 Married Filing Jointly $14,700 Married Filing Separately $7,350 Head of Household $10,350 Qualifying Surviving Spouse with a Dependent Child $13,700 Other income tax considerations in Oklahoma Along with standard wages and salaries, Oklahoma taxes various types of income differently.
