Sec. 1. (a) Contributions unpaid on the date on which they are due and payable, as prescribed by the commissioner, shall bear interest at the rate of one percent (1%) per month or fraction thereof from and after such date until payment, plus accrued interest, is received by the department. The department may prescribe fair and reasonable regulations pursuant to which such interest shall not accrue.
(b) If the failure to pay any part or all of the delinquent contributions is due to negligence or intentional disregard of authorized rules, regulations, or notices, but without intent to defraud, there shall be added, as a penalty, ten percent (10%) of the total amount of contributions unpaid, which penalty shall become due and payable upon notice and demand by the commissioner.
(c) If the commissioner finds that the failure to pay any part or all of delinquent contributions is due to fraud with intent to evade the payment of contributions, there shall be added, as a penalty, fifty percent (50%) of the total amount of delinquent contributions, which penalty shall become due and payable upon notice and demand by the commissioner.
(d) Interest and penalties collected pursuant to this section shall be paid into the special employment and training services fund.
