THE SENATE	S.B. NO.	2719
THIRTY-THIRD LEGISLATURE, 2026
STATE OF HAWAII

A BILL FOR AN ACT

RELATING TO TAXATION.

BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF HAWAII:

SECTION 1. The legislature finds that based on the carbon pricing study commissioned under Act 122, Session Laws of Hawaii 2019, and the findings and recommendations of the 2020-2022 tax review commission's final report, establishing a carbon cashback program that increases taxes on fossil fuels and distributes most of the new tax revenues back to taxpayers would be a cost‑effective and equitable way to reduce the State's greenhouse gas emissions, as well as to provide financial relief to most households in the State.

Accordingly, the purpose of this Act is to establish a carbon cashback program that:

(1) Gradually increases the environmental response, energy, carbon emissions, and food security tax to reduce fossil fuel imports and reduce greenhouse gas emissions and pollution in furtherance of the State's zero emissions clean economy target established in Act 15, Session Laws of Hawaii 2018; and

(2) Distributes most of the new tax revenues as refundable income tax credits to mitigate the effect of the increased tax on income taxpayers and provide net financial benefits to most of them.

SECTION 2. Chapter 231, Hawaii Revised Statutes, is amended by adding a new section to be appropriately designated and to read as follows:

"§231-   Carbon emissions tax and dividend special fund. (a) There is established the carbon emissions tax and dividend special fund, into which shall be deposited the amount specified by section 243-3.5.

(b) Moneys in the carbon emissions tax and dividend special fund shall be administered by the department of taxation and shall be expended for salaries, contracted services, supplies, and other administrative expenses to:

(1) Administer the environmental response, energy, carbon emissions, and food security tax;

(2) Administer the carbon cashback tax credit established by section 235-  ; and

(3) Increase public awareness and interest in the carbon cashback tax credit established by section 235-   and other refundable tax credits.

SECTION 3. Chapter 235, Hawaii Revised Statutes, is amended by adding a new section to part III to be appropriately designated and to read as follows:

"§235-   Carbon cashback tax credit. (a) There shall be allowed to each qualifying taxpayer subject to the tax imposed under this chapter, a carbon cashback tax credit that shall be applied against the taxpayer's net income tax liability, if any, imposed by this chapter for the subject taxable year in which the credit is properly claimed.

(b) The amount of the tax credit for the first taxable year beginning after December 31, 2025, shall be equal to the sum of the following:

(1) $52 for a taxpayer filing as single or married filing separately;

(2) $52 for a taxpayer filing as a head of household;

(3) $104 for a taxpayer filing a joint return or as a surviving spouse; and

(4) $26 per dependent claimed by the taxpayer.

(c) The amount of the tax credit for any taxable year beginning after December 31, 2026, shall be as specified in subsection (d), where the value of one share shall be the amount of revenue collected through the environmental response, energy, carbon emissions, and food security tax specified under section 243—3.5 and deposited into the general fund in the calendar year that ends with the end of the corresponding taxable year, divided by the number of whole shares, where the number of whole shares is 1,440,000.

(d) The amount of the credit for any taxable year beginning after December 31, 2026, shall be equal to the sum of the following:

(1) One share for a taxpayer filing as single or married filing separately;

(2) One share for a taxpayer filing as a head of household;

(3) Two shares for a taxpayer filing a joint return or as a surviving spouse; and

(4) 0.5 shares per dependent claimed by the taxpayer.

(e) If the tax credit allowed to the taxpayer under this section exceeds the amount of the income tax payments due from the taxpayer, the excess of credit over payments due shall be refunded to the taxpayer; provided that the tax credit properly allowed to a taxpayer who has no income tax liability shall be paid to the taxpayer; provided further that no refunds or payments on account of the tax credit allowed by this section shall be made for amounts less than $1.

To be allowed a tax credit under this section, the individual income tax return, including amended returns, shall be filed on or before the end of the twelfth month following the close of the taxable year for which the credit is allowed. Failure to comply with the foregoing provision shall constitute a waiver of the right to be issued the credit.

(f) Any carbon cashback tax credits not issued pursuant to this section for the most recent taxable year for which the return filing deadline has passed shall be allocated to the Med-QUEST division of the department of human services that administers the State's medicaid program. To determine the amount of credits not issued, the department of taxation shall calculate the product of the number of whole shares and the value of one share for the relevant taxable year, less the total amount of eligible allowances for carbon cashback tax credits issued for the relevant taxable year. The department of taxation may use a substantively similar calculation to determine the amount.

(g) The director of taxation:

(1) Shall prepare any forms that may be necessary to allow issuance of a tax credit under this section in a manner that does not require an explicit claim by the taxpayer;

(2) Shall alert eligible taxpayers of the tax credit using appropriate means; and

(3) May adopt rules under chapter 91 necessary to effectuate the purposes of this section.

(h) All of the provisions relating to assessments and refunds under this chapter and under section 231-23(c)(1) shall apply to the tax credit under this section.

(i) As used in this section, "qualifying taxpayer" means a person subject to the taxes imposed by this chapter. "Qualifying taxpayer" does not include any person who is claimed or is otherwise eligible to be claimed as a dependent by another taxpayer for federal or Hawaii state individual income tax purposes."

SECTION 4. Section 128D-2, Hawaii Revised Statutes, is amended by amending subsection (a) to read as follows:

"(a) There is created within the state treasury an environmental response revolving fund, which shall consist of moneys appropriated to the fund by the legislature, moneys paid to the fund as a result of departmental compliance proceedings, moneys paid to the fund pursuant to court-ordered awards or judgments, moneys paid to the fund in court-approved or out‑of‑court settlements, all interest attributable to investment of money deposited in the fund, moneys deposited in the fund from the environmental response, energy, carbon emissions, and food security tax pursuant to section 243-3.5, and moneys allotted to the fund from other sources."

SECTION 5. Section 201-12.8, Hawaii Revised Statutes, is amended by amending subsection (a) to read as follows:
