Oklahoma Fill-In 2-D Form Instructions
Please print and read instructions before completing the 511 2-D Form.


    What is a 2-D barcode? The barcode is created as the fill-in fields of the form are completed. It contains all the information required to process your return. This allows the Oklahoma Tax Commission to scan the barcode and eliminates the need for manual data entry. This results in faster, more efficient processing of tax returns and quicker refunds to the taxpayer.

    This form has been enhanced to calculate mathematically and will create a 2-D barcode when printed.

    You may need to download the instruction packet for this form before you begin. (511 Packet)

    In order to ensure calculations work correctly, please observe the following:

  • Fields highlighted in yellow are calculated fields. Amounts cannot be entered into these fields. The amounts reflected in the yellow fields can only be changed by entering new amounts in a field which is part of the calculations.

  • Fields that are blank, or highlighted in blue, will allow you to enter an amount.

  • If a field requires computation from a schedule, you will not be able to enter an amount. You will have to complete the schedule and the total will automatically reflect in the correct line of the form. If you are not required to complete a schedule, the field will be open and you can enter an amount directly on that line.

  • Please be sure to check all your information prior to printing. Do not make any changes to the printed form. If changes are needed, please make them on the computer, then, print the form. Changes made to the form after printing will not be reflected in the 2-D barcode, and could result in a delay in processing your return.

    When mailing your return be sure to include any required documentation such as W2's, 1099's or other withholding statements, as well as any required Federal or Oklahoma forms or schedules. If your return is a tax due return, make your check payable to the Oklahoma Tax Commission. Returns should be mailed to:

Oklahoma Tax Commission
Post Office Box 269045
Oklahoma City, OK 73126-9045
