39-14-303(a) shall pay monthly tax payments to the department. The payment shall be determined by the taxpayer based on the value of the gross product produced and saved during the second preceding month, and tax computed on value at rates prescribed in this article. The monthly tax payments are due on or before the twenty-fifth day of the second month following the month of production. If the report the taxpayer is required to file shows tax due, the taxpayer shall pay the tax due when the report is filed. The department may allow extensions for paying taxes by regulation. The department may, if an extension is granted, request the payment of the reasonable estimate of ninety percent (90%) of the tax by the statutory due date, with the remaining tax remitted with the extended return;

(iv) If a taxpayer's liability for severance tax imposed under this article is less than thirty thousand dollars ($30,000.00) for the preceding calendar year, monthly payment requirements are waived and the taxpayer shall pay the tax annually. The annual payment is due on February 25 of the year following the year in which production occurred. If a taxpayer who pays annually accumulates an annual liability exceeding thirty thousand dollars ($30,000.00), that taxpayer shall commence remitting tax payments as provided in paragraph (iii) of this subsection during the production year following the year in which the accumulated tax liability exceeded thirty thousand dollars ($30,000.00). It is the taxpayer's responsibility to notify the department concerning the change from annual to monthly payment requirements or from monthly to annual payment.
