What if I cannot file by the due date?

You may request an extension of time to file your Oklahoma income tax return. If you have a valid extension of time to file your Federal return and no Oklahoma tax is owed, your Federal extension automatically extends the due date of your Oklahoma return. A copy of the Federal extension must be enclosed with your Oklahoma return. If your Federal return is not extended or an Oklahoma tax is owed, an extension of time to file your Oklahoma return can be granted on Form 504.

Keep in mind that an extension of time to file is not an extension of time to pay the tax. An extension is valid only when 90% of the tax is paid by the original due date of the tax return.
