On or before June 15 of each year, the department of revenue shall notify each public utility subject to this article of the amount of its fee for the ensuing fiscal year beginning July 1, computed by multiplying its gross intrastate utility operating revenues for the preceding calendar year, as set forth in its return filed for that purpose, by the percentage determined in accordance with section 40-2-112; but the department of revenue shall not require a public utility that is a telephone corporation to pay a fee in excess of one-fifth of one percent of its gross intrastate utility operating revenues for the preceding calendar year and shall not require any other public utility to pay a fee in excess of one-quarter of one percent of its gross intrastate utility operating revenues for the preceding calendar year. Each public utility shall pay the fee assessed against it to the department of revenue in equal quarterly installments on or before July 15, October 15, January 15, and April 15 in each fiscal year. If a public utility does not make a payment by one of the quarterly deadlines, the department of revenue shall charge the public utility a penalty of ten percent of the installment due, together with interest at the rate of one percent per month on the amount of the unpaid installment until the full amount of the installment, penalty, and interest has been paid. Upon failure, refusal, or neglect of any public utility to pay the fee, or any penalty or interest, the attorney general shall bring suit in the name of the state to collect the amount due.
