Gross Production: Registration System (Form 320-A/C)
The Oklahoma Tax Commission's Gross Production System is now available for your use. This system allows operators the ability to electronically file OTC lease registration forms, 320-A and 320-C.
The system will allow users to register new wells; request assignment of the lease production unit number (PUN); make changes to existing lease record information; and, make all other changes currently found on the Form 320-C.
It is important to download the Instructional Packet (available below) before accessing the system for the first time. This packet will walk you through the registration process and initial filings. Once you have downloaded the instructions, you may access the Gross Production System through the link below.
Please note that registering for the system does not register you to file Gross Production Tax. Registration forms and information to remit Gross Production taxes may be found in the Forms and Publications area of this website.
If at any time during the registration process you should need assistance, please contact the OTC Webfile Support Group. Once registered, if assistance is needed, please call the OTC’s Taxpayer Assistance Division at (405) 521-3674.
