State of Hawaii Incentives
1) Hawaii Renewable Energy Technologies Income Tax Credit
Summary: The Hawaii Department of Taxation oversees the Hawaii Renewable Energy Technologies Income Tax Credit.
2) Database of Renewable Energy and Energy Efficiency Incentives Available in Hawaii
Summary: The North Carolina Clean Energy Technology Center currently provides a free and open resource summarizing the incentives available for clean energy technologies in each state.
3) Property Tax Incentives
Summary: Certain counties within the State of Hawaii offer property tax incentives related to renewable energy and energy efficiency property investments.
4) Hawaii Enterprise Zones
Summary: Currently, wind energy producers may be eligible for this incentive that provides a 100% general excise tax exemption as well as reductions in state income taxes in exchange for demonstrated job growth. This incentive is available statewide in designated geographic areas.
5) Hawaii Foreign Trade Zone
Summary: Hawaii’s Foreign Trade Zone Program supports manufacturing and small business activity in Hawaii by encouraging companies to compete in export markets and providing growth to new companies that import and export merchandise, including renewable energy and energy efficiency equipment.
6) Renewable Fuels Production Tax Credit
Per HRS 235-110.31, the Renewable Fuels Production Tax Credit will no longer be available after the 2021 tax year. Pre-qualified (i.e. have previously and timely submitted the required forms for 2021) renewable fuel producers seeking to claim the credit for the 2021 tax year must also completely fill out and submit to DBEDT the “RFPTC- Independent Third-Party Certified Statement” Forms by the designated deadline.

- Hawaii Revised Statutes, 235-110.31 as amended to date; and
- The Department of Taxation’s Tax Information Release (TIR) No. 2018-03.
Visit the Database of State Incentives for Renewables and Efficiency (DSIRE) website for information on the federal tax credits available for renewable energy and energy efficiency systems.
1) Business Energy Investment Tax Credit (ITC)
Summary: The federal Business Energy Investment Tax Credit (ITC) has been amended a number of times. The Taxpayer Certainty and Disaster Tax Relief Act of 2020, signed in December 2020, extended this tax credit for certain technologies. The table below shows the value of the investment tax credit for each technology by year. The expiration date for solar technologies and wind is based on when construction begins. For all other technologies, the expiration date is based on when the system is placed in service (fully installed and being used for its intended purpose).
|PV, Solar Water Heating, Solar Space Heating/Cooling, Solar Process Heat||26%||26%||26%||22%||22%||22%||10%|
|Hybrid Solar Lighting, Fuel Cells, Small Wind, Waste Energy Recovery||26%||26%||26%||22%||N/A||N/A||N/A|
|Geothermal Heat Pumps, Microtubines, Combine Heat and Power Systems||10%||10%||10%||10%||N/A||N/A||N/A|
2) Renewable Energy Production Tax Credit (PTC)
Summary: Wind facilities commencing construction by December 31, 2019 can qualify for this credit. The value of the credit steps down in 2017, 2018 and 2019. See below for more information. For all other technologies, the credit is not available for systems whose construction commenced after December 31, 2016.
3) Residential Renewable Energy Tax Credit
Summary: A taxpayer may claim a credit of 30% of qualified expenditures for a system that serves a dwelling unit located in the United States that is owned and used as a residence by the taxpayer.
4) Corporate Depreciation (Modified Accelerated Cost-Recovery System)
Summary: The Consolidated Appropriations Act, signed in December 2015, extended the “placed in service” deadline for bonus depreciation. Equipment placed in service before January 1, 2018 can qualify for 50% bonus depreciation. Equipment placed in service during 2018 can qualify for 40% bonus depreciation. And equipment placed in service during 2019 can qualify for 30% bonus depreciation. Under the federal Modified Accelerated Cost-Recovery System (MACRS), businesses may recover investments in certain property through depreciation deductions. The MACRS establishes a set of class lives for various types of property, ranging from three to 50 years, over which the property may be depreciated. A number of renewable energy technologies are classified as five-year property (26 USC § 168(e)(3)(B)(vi)) under the MACRS, which refers to 26 USC § 48(a)(3)(A), often known as the energy investment tax credit or ITC to define eligible property. Such property currently includes:
- a variety of solar-electric and solar-thermal technologies
- fuel cells and microturbines
- geothermal electric
- direct-use geothermal and geothermal heat pumps
- small wind (100 kW or less)
- combined heat and power (CHP)
- the provision which defines ITC technologies as eligible also adds the general term “wind” as an eligible technology, extending the five-year schedule to large wind facilities as well
