For companies in the oil and gas industry, Byrne & Clayton reviews client data in order to complete an analysis of the appropriate severance tax levels.  As appropriate, this review includes a calculation of the taxable value using state approved netback methodologies.  As necessary, we file appeals and prepare the necessary documentation for hearings in a timely manner.  Abatement claims are filed with the county assessor, and ammended severance tax returns and refund requests are also filed.
