GENERAL QUESTIONS

Beginning with tax year 2013, the Form 511 is used to file an amended resident return.

The Form 511X is for tax year 2012 and prior. Part-year and nonresidents use Form 511NR.

 

How to complete an amended return using Form 511 or Form 511NR, place an “X” in the “Amended Return” checkbox at the top of the form, page 1. Complete the amended return. The return contains a line to enter any amount(s) paid with the original return plus any amount(s) paid after it was filed and a line to enter any refund previously received or overpayment applied. Complete the “Amended Return Information” schedule.


To claim a refund, your amended return must be filed within three years from the date tax, penalty and interest was paid. For most taxpayers, the three-year period begins on the original due date of the Oklahoma tax return. Estimated tax and withholding are deemed paid on the original due date, excluding extensions. For current Oklahoma tax forms, visit the Forms page.
