Bill Overview

Analyzed Economic Effects

5 provisions identified: 0 benefits, 4 costs, 1 mixed.

Higher top tax rates for high earners

Hawaii changes income tax brackets for joint filers, surviving spouses, and other individual filers. New schedules apply to tax years beginning after December 31, 2026, and change again for years beginning after December 31, 2028. The top marginal rate reaches 13% for high-income taxpayers. Your tax bill depends on your filing status, income, and the schedule for that year.

Household renewable energy credits face limits

For tax years beginning after December 31, 2025, individuals can claim the credit for eligible systems installed in Hawaii only if adjusted gross income is $175,000 or less, or $350,000 or less for joint filers. Married people filing separately qualify only to the extent they could qualify by filing jointly. Solar credits are generally 35% and wind credits 20%; single-family system caps include $2,250 for solar water heating, $5,000 for other solar, and $1,500 for wind. The annual pool is $40 million for 2027 through 2030; when claims exceed it, credits are divided in proportion to claimed costs. Claimants file a certified statement by March 1, and the Energy Office sends certified amounts by May 31 when the cap is reached. The law also says the credit ends for tax years starting after December 31, 2029, though it lists a cap for 2030.

Businesses lose capital goods tax credit

Businesses can claim a refundable credit generally equal to 4% of eligible depreciable property costs for property placed in service in Hawaii. The credit does not apply to tax years beginning after December 31, 2027. The amount a business loses depends on the cost of its eligible property.

Renewable fuel producers get capped tax credit

Qualifying renewable fuel producers can claim 20 cents per 76,000 British thermal units of fuel sold for distribution in Hawaii. Fuel must have lower lifecycle emissions than fossil fuels, and a producer must make at least 2.5 billion British thermal units a year. The credit is capped at $3.5 million per taxpayer each year and $20 million statewide per calendar year. Related taxpayers share a maximum 10-year credit period, starting when the production threshold is first met. Producers must submit a third-party-certified report to the Energy Office within 30 days after year-end. The credit applies to tax years beginning before January 1, 2029.

Technology businesses lose two tax credits

Hawaii repeals tax credits for high-technology business investment and technology infrastructure renovation starting January 1, 2029. The supplied provisions do not state the credits' amounts or full eligibility rules, so the value and specific affected taxpayers are not clear.
