SB430 amends Hawaii’s tax refund statute to change how interest is paid on tax overpayments. Under current law, refunds of overpaid taxes can accrue interest at a statutory rate; this bill would instead tie the state’s refund interest rate to the federal rate under Internal Revenue Code section 6621(a)(1), using the rate in effect on January 1 of each year and compounding it daily after the 90-day refund period. The bill applies this same approach to overpayments shown on original returns, overpayments discovered through amended returns or by the director, and certain credit-related refunds.
The measure also preserves the existing 90-day refund window before interest begins to accrue, and it keeps the special rule for net operating loss carrybacks, under which certain overpayments are treated as made at the close of the loss year and related underpayment interest is not charged on amounts offset by the carryback. The bill is described as an income tax refund measure and is intended to align Hawaii’s refund interest treatment more closely with the federal government’s rate structure.
Impact
SB430 would amend section 231-23, Hawaii Revised Statutes, affecting the Department of Taxation’s administration of refund interest on overpayments. It would replace the current fixed statutory interest rate with a variable federal benchmark rate and require daily compounding after the 90-day period, which could increase or decrease the amount of interest paid depending on prevailing federal rates. The bill would directly affect taxpayers receiving refunds, the Department of Taxation’s refund processing, and the calculation of interest on amended returns, director-determined overpayments, credits, and net operating loss carrybacks.
Sentiment
The available voting history suggests broad support for the bill. The Senate Ways and Means Committee passed SB430 with amendments by a 13-0 vote, indicating unanimous support in that committee. No committee transcript is available, but the bill’s progress and the absence of recorded opposition in the provided materials suggest the measure was generally viewed favorably as a technical tax administration change.
Contention
The main policy issue appears to be the choice of interest rate and compounding method for tax refunds. By moving from a fixed state rate to the federal rate under IRC section 6621(a)(1), the bill could change the cost to the state and the amount taxpayers receive, depending on market conditions. Any concern would likely center on fiscal impact to the state treasury, administrative complexity in tracking a changing federal rate, and whether daily compounding is appropriate.
