Hawaii cash rounding law

H.R. 10167 has passed congress. It is not yet law, and it does not by itself change Hawaii's enacted requirements below. Section 4 of the bill is a safe harbor for adherence to the federal rounding conduct it describes, not a blanket preemption of state law. See the Federal Cash-Rounding Standard for the pending federal framework and its current status.

Hawaii permits, but does not require, any person selling goods or services in a cash transaction, any party otherwise transacting in cash, or an employer paying cash wages, to round the total transaction amount to the nearest five cents using the standard up and down by final digit method, with totals under five cents rounded up to five cents. Codified in HRS chapter 481B by Act 159 (SB 3255), effective July 1, 2026.

Tax-inclusive rounding. The total transaction amount subject to rounding is defined to include fees, surcharges, and taxes. The statute does not separately state that tax is computed on the pre-rounded amount.

Expressly excluded. Rounding does not apply to any transaction paid by demand or negotiable instrument, electronic fund transfer, check, gift card, money order, credit card, or other like instrument.

Two express protections. Private actions under HRS 480-2 to enforce the section are barred, and a person engaging in compliant rounding is not subject to HRS 486-116, the weights-and-measures penalty provision.
