Every surety, other than a self-insurer shall, under oath of the person or officers making the report, within thirty (30) days after February 1 and July 1 of each year, report to the commission the net amount of premium written on worker’s compensation insurance in this state during the preceding six (6) months’ period, and every self-insurer shall, within thirty (30) days after February 1 and July 1 of each year, report in the same manner to the commission the total payroll for the preceding six (6) months’ period. The commission shall have the right, at any time and as often as it requires, to verify the worker’s compensation premiums written by any surety, and to inspect or cause to be inspected the records of any surety underwriting or authorized to underwrite worker’s compensation liability in the state of Idaho for premiums written verification purposes.
