Haw. Rev. Stat. § 88-124: Payment of state contributions to the system.

(a) The State shall pay to the various funds of the system the amounts payable by the State under this part. Payments shall be made:

(1) On a monthly basis, within thirty days after the end of each month; or

(2) In advance, in an amount greater than the amount payable for the current fiscal quarter, taking into account amounts previously paid during the quarter and any offsets for any excess contributions in the previous quarter.

(b) The system shall determine the actual amount owed by the State under this part for each fiscal quarter, commencing with the first fiscal quarter of fiscal year 2005-2006. The actual amounts owed by the State for the fiscal quarter shall be compared against the amounts paid in the fiscal quarter and any excess contributions from the previous quarter. Any additional contributions owed by the State for a fiscal quarter shall be paid before the end of the next fiscal quarter. Any excess contributions by the State may be used to offset amounts owed by the State for the next fiscal quarter.
