Section 7-15-4 - Interest; penaltiesA. If any trip tax is not paid when due, interest shall be paid to the state on such amount from the date on which the trip tax becomes due until it is paid. Interest shall be due to the state at the rate of fifteen percent a year, computed at the rate of one and one-quarter percent per month or any fraction thereof, except that, if the amount of interest due at the time payment is made is less than one dollar ($1.00), then no interest shall be due. Nothing in this subsection shall be construed to impose interest on interest or interest on penalty. B. In the case of failure, due to negligence or disregard of rules and regulations, but without intent to defraud, to pay when due any amount of trip tax required to be paid, there shall be added to the amount as penalty two percent per month, or any fraction thereof, from the date on which the trip tax becomes due until the time payment is made, provided that the total penalty shall not exceed ten percent of the amount nor shall it be less than a minimum of five dollars ($5.00). C. In the case of failure to pay when due any amount of trip tax required to be paid, with intent to defraud the state, there shall be added to the amount fifty percent thereof or a minimum of twenty-five dollars ($25.00), whichever is greater, as penalty. 1978 Comp., § 7-15-4, enacted by Laws 1988, ch. 73, § 25.
