Oklahoma State Tax Forms for 2009, 2010
If you earned sufficient income in the State of Oklahoma and are an Oklahoma resident, you are required to file an Oklahoma state tax return. It doesn’t matter where the source of income came from. You will need to file Form 511.
If you had Oklahoma taxes withheld or have made estimated tax payments you will file Form 511. Even if you don’t have a filing requirement, there is a section in the name and address area where you can check the box to say that there is no filing requirement.
Part-Year and Nonresidents
If you happen to be a part-year resident, you have the same filing requirements as a resident. You will file for the period of time you were a resident. Now during the time of being a nonresident, an Oklahoma return still will need to be filed if during your part-year residency your gross income from Oklahoma sources was $1,000 or more. You will need to file Form 511NR.
Nonresidents who have made $1,000 or more from sources in the state of Oklahoma are required to file an income tax return. If you made less than $1,000 but, had Oklahoma taxes withheld will want to file Form 511NR for a possible refund.
Am I a Resident?
You are an Oklahoma resident if your main home is in Oklahoma and you live there for the entire year. Your main home or “Domicile” is your true, fixed, and permanent home. Whenever you go away as on vacation, business or schooling, it is the place you always return to.
When is my Return Due?
Usually your state return is due April 15th, the same exact date as your federal return. There are a few exceptions to the due date. If you have someone prepare your taxes for you or if you file them electronically then, your due date is extended to April 20th. Don’t think you can put a payment in the mail at that time because you can’t. Any taxes due must be paid and received by them by April 20th. If you don’t pay on time you will be struck with a penalty and you will pay interest. Other exceptions include the due date falling on a weekend or holiday then, it’s due on the next business day. The other exception would be disasters such as a tornado. You will want to search the state website to check on extensions due to disasters.
