SB2525 reinstates Hawaii’s income tax credit for cesspool upgrade, conversion, or connection costs. The bill allows taxpayers to claim a credit equal to 35 percent of qualified expenses, subject to caps of $14,000 for conversion to a septic system, $17,500 for conversion to an aerobic treatment unit system, and $28,000 for elimination through connection to a sewerage system. It also extends the credit to residential large-capacity cesspools on a per-dwelling basis, carries forward unused credit amounts, and requires claims to be filed within 12 months after the close of the taxable year.
The measure is tied to the state’s broader effort to eliminate cesspools by 2050 and responds to the expiration of the prior credit that had been available under earlier law. The bill states that the new credit is intended to offset substantial private costs associated with compliance, especially for sewer connections, and it applies beginning with taxable years after December 31, 2026. It also coordinates administration between the Department of Health, which certifies qualified expenses, and the Department of Taxation, which issues forms and may adopt implementing rules.
SB2525 would add a new income tax credit provision to chapter 235, Hawaii Revised Statutes, and would amend section 23-95 to include the new cesspool credit among the tax provisions subject to that section. It would effectively revive and update the former cesspool tax credit, while excluding taxpayers who already received federal, state, county, or private grants for the same project. The bill would affect homeowners, property owners, partnerships, S corporations, estates, and trusts that incur eligible cesspool remediation costs, and it would require administrative coordination between the Department of Health and the Department of Taxation.
The bill appears generally supportive of cesspool remediation and water-quality protection, with the legislative findings emphasizing the environmental harm caused by untreated sewage and the need to help taxpayers meet mandated upgrade deadlines. The absence of recorded opposition, votes, or committee testimony in the provided materials suggests no documented controversy in the available record. The bill’s framing as part of the Hawaii Council of Mayors package also indicates policy support for wastewater infrastructure improvements.
The main policy tension is fiscal and administrative rather than ideological: the bill provides a tax expenditure to subsidize private compliance costs, which may raise concerns about state revenue impacts and whether the credit is the most efficient way to accelerate cesspool replacement. Another possible point of contention is equity, since taxpayers who already received grants are excluded, and the credit may be more accessible to property owners who can finance upfront costs before claiming reimbursement through the tax system. No specific objections, amendments, or opposing viewpoints are included in the provided committee or vote history.
