The Oklahoma Tax Commission took down the access to production records. Their site now says:
ATTENTION: This legacy Gross Production Registration System (GPRS) has been retired. Our new Gross Production System is now live on OkTAP (oktap.tax.ok.gov) and can be used for all filing and registration needs. For questions, contact the Oklahoma Tax Commission at firstname.lastname@example.org
Is there an easy way to access this information?
