Figure Out Your Residency Status So You File the Right Forms
Make sure to determine your residency status before you file your state income taxes. Even if you don’t live in Oklahoma, you may have earned income there. See below to find out if you need to file a state income tax return with Oklahoma.
If your permanent residence was in Oklahoma for the entire year, you are considered an Oklahoma resident. If you filed a federal return as an Oklahoma resident or if you earned more than $12,500 (married, filing separately), $15,000 (single), $19,000 (head of household), or $25,000 (married, filing jointly), you are required to file an Oklahoma state income tax return. If you were older than 65 years of age or blind at the end of the tax year, you should check if you are eligible for a $1,000 exemption. If your income is lower than the limits stated above, you are not required to file an Oklahoma state income tax return. However, if any of your income was withheld, you will need to file a tax return in order to receive a refund for those withholdings. Oklahoma residents file Form-511 for state income taxes. For more information on how to fill out Form-511, you can download the 2016 Oklahoma Resident Individual Income Tax Forms and Instructions Booklet above.
If you only lived (permanent residence) in Oklahoma for part of the year or moved to or from Oklahoma within the tax year, you are a part-year Oklahoma resident. You follow the same steps when filing state income taxes as full-time residents for the period that you lived in Oklahoma. For the time you lived outside of Oklahoma, you will file as a nonresident, using Form-511NR to file a part-year return. If you need further information regarding Form-511NR, you can download the 2016 Oklahoma Individual Tax Forms and Instructions for Nonresidents and Part-Year Residents above.
Oklahoma Residents Working Out of State
If you worked outside of Oklahoma, while retaining your Oklahoma residency, Oklahoma will collect taxes on any earnings made out of state, regardless of which state. Since most states will also be taxing you on that income, you will be taxed twice on this income (dual taxation). In order to avoid dual taxation, file credit Form-511TX along with your Oklahoma state tax return. You will also need to attach your W-2, which your employer should have provided, to your Form-511 income tax return and report any income earned, regardless of in which state. For more information on how to fill out Form-511, you can download the 2016 Oklahoma Resident Individual Income Tax Forms and Instructions Booklet above.
Work in Oklahoma but Live in Another State
If your permanent residence was outside of Oklahoma for the entire year, then you are a nonresident. If you earned more than $1,000 in Oklahoma and are a nonresident, then you are required to file a nonresident return in Oklahoma. Even if you don’t have to file a nonresident return, you may have had income withheld that you want refunded and you will need to file a return for that refund.
Oklahoma considers taxable income to be income earned from Limited Liability Companies (LLC) distribution, partnerships doing business in Oklahoma (this includes income earned from shares, gains, losses or deductions), Subchapter S corporations, earnings from the sales or rental of property in Oklahoma and gambling winnings. Use Form-511NR to file an Oklahoma nonresident return and if you need any further information, you can download the 2016 Oklahoma Individual Tax Forms and Instructions for Nonresidents and Part-Year Residents above.
If you are a nonresident and you sold property in Oklahoma, you follow the same instructions as nonresidents who worked in Oklahoma. See “Work in Oklahoma but Live in Another State”.
