Idaho Heat Pump Rebates & Tax Credits: Your Comprehensive Guide

Explore Idaho's heat pump rebates, federal tax credits, and local utility incentives. Learn how to save on energy-efficient upgrades for your home or business in Idaho. Updated for 2024.

Idaho homeowners and businesses can combine federal tax credits, state tax deductions, low-interest loans, and utility rebates to reduce heat pump installation costs. This guide details available incentives and how to apply for them.

Quick Answer: Idaho Heat Pump Savings at a Glance

Idaho residents and businesses can access several main incentive categories:

Federal tax credit (IRS §25C): 30% of installation cost, up to $2,000 annually for qualifying heat pumps. Claim on IRS Form 5695. No income limit.

Idaho state tax deduction: 40% of system cost in year one, then 20% per year for three more years. Maximum $5,000 annually, $20,000 total lifetime. Administered by the Idaho Tax Commission.

Idaho OEMR low-interest loan program: Currently closed. The Office of Energy and Mineral Resources (OEMR) expects to reopen the State Energy Loan Program in Summer 2025. Check oemr.idaho.gov/loan-program/ for updates.

Utility rebates: Kootenai Electric Cooperative, Idaho Power, and Idaho Falls Power each offer separate programs with unique eligibility rules and amounts.

Stackability: The federal §25C credit can be combined with the Idaho state deduction and utility rebates. A deduction lowers taxable income, while a credit directly reduces tax owed. Consult a tax professional to maximize your savings.

Federal Incentives for Idaho Heat Pump Installations

The primary federal incentive is the Energy Efficient Home Improvement Credit (IRS §25C).

What the Credit Covers

The credit equals 30% of a qualifying heat pump's installed cost, capped at $2,000 per tax year (IRS §25C). This $2,000 cap applies specifically to heat pumps and heat pump water heaters. Separate annual caps exist for other improvements: $600 for qualifying HVAC equipment not covered by the heat pump cap, $600 for exterior windows, and $150 for a home energy audit.

Qualifying Equipment

Your equipment must meet one of these standards:

Air-source heat pumps: Must meet the Consortium for Energy Efficiency (CEE) highest efficiency tier in effect when purchased, or qualify as ENERGY STAR Most Efficient.
Ground-source (geothermal) heat pumps: Must meet ENERGY STAR requirements.
Heat pump water heaters: Must meet the CEE highest efficiency tier or ENERGY STAR Most Efficient.

Your installer should provide an AHRI (Air-Conditioning, Heating, and Refrigeration Institute) certificate confirming the equipment meets the required efficiency rating. Keep this document with your tax records.

How to Claim It

File IRS Form 5695 (Residential Energy Credits) with your federal tax return for the year the installation is completed. The credit applies to the tax year the equipment is placed in service, not the year you paid a deposit or signed a contract.

Annual Limits and Carry-Forward

The $2,000 annual cap resets each tax year. There is no carry-forward provision; if the credit exceeds your tax liability for the year, the unused portion cannot be applied to future years. Consult a tax professional to see if splitting a project across two tax years could allow you to claim the credit twice.

Idaho State-Specific Heat Pump Tax Deductions & Loan Programs

Residential Alternative Energy Tax Deduction

Idaho offers a state income tax deduction for the cost of qualifying alternative energy systems, including geothermal, solar, wind, and certain biomass devices used for heating or electricity generation (Idaho Tax Commission, Residential Alternative Energy Tax Deduction).

The deduction schedule is:

Year	Deduction Rate	Annual Maximum
Year of installation	40% of system cost	$5,000
Year 2	20% of system cost	$5,000
Year 3	20% of system cost	$5,000
Year 4	20% of system cost	$5,000
Total	100%	$20,000

This is a deduction, not a credit, so your actual tax savings depend on your Idaho marginal income tax rate. The deduction applies to geothermal heat pump systems. Air-source heat pumps are not explicitly listed under the geothermal category. Confirm eligibility with the Idaho Tax Commission before assuming your specific equipment qualifies. Eligible biomass devices, like pellet stoves and EPA-certified wood stoves, are separate from heat pumps.

Low-Interest Energy Loan Programs (OEMR)

The Idaho Governor's Office of Energy and Mineral Resources (OEMR) State Energy Loan Program provides low-interest loans for energy efficiency improvements to single-family homes, including HVAC systems. Eligible projects include insulation, weatherization, windows, lighting, appliances, and renewable energy installations.

Current Status: The program is closed. OEMR expects to reopen it in Summer 2025. Monitor oemr.idaho.gov/loan-program/ for updates. When available, specific loan terms, interest rates, and maximum amounts will vary. Consult OEMR directly for current figures.

Property Tax Exemption for Geothermal Energy Producers

Idaho changed how geothermal energy producers are taxed, moving from a property tax to a production-based tax (Idaho State Tax Commission). This exemption applies to commercial geothermal energy producers, not homeowners installing a geothermal heat pump for personal use. Commercial geothermal facility operators should consult the Idaho State Tax Commission for details.

Clean Energy Project Bond Program

The Idaho Energy Resources Authority (IERA) was created by H.B. 106 (2005) and authorized by S.B. 1192 to issue bonds for financing renewable energy construction projects. This program targets electric utilities and independent developers building generation and transmission infrastructure, not direct consumer rebates or loans. Residential and small commercial customers should explore other programs.

Recent Changes & Updates to Idaho Heat Pump Incentives

OEMR State Energy Loan Program: Currently Closed

The closure of the OEMR State Energy Loan Program is a significant recent change affecting Idaho heat pump financing. The Office of Energy and Mineral Resources announced the program is currently closed, with reopening anticipated in Summer 2025 (OEMR, oemr.idaho.gov/loan-program/). If you plan an installation and intend to use this loan, allow time to monitor its reopening or arrange alternative interim financing.

IRA Program Rollout

The federal HOMES Rebate Program (IRA §50122) and the High-Efficiency Electric Home Rebate Act (HEAR, IRA §50123) are state-administered programs that launched in most states between 2024 and 2025. Confirm with OEMR or the Idaho Department of Commerce whether Idaho has launched either program and if heat pump installations qualify under the state's implementation plan. These programs can provide up to $8,000 for qualifying heat pump HVAC installations (IRA §50123) for households at or below 150% of the area median income.

Stackability summary: IRS §25C stacks with the Idaho state deduction and utility rebates. HEAR (IRA §50123) stacks with §25C but cannot be combined with the HOMES rebate (IRA §50122) on the same measure.

Federal Tax Considerations

Heat pump rebates can provide significant federal tax benefits under specific provisions in the Internal Revenue Code (IRC). Notably, IRC § 25C and § 25D offer credits for energy-efficient heat pumps that can help offset costs for both individuals and businesses.

IRC § 25C: Provides a credit of 30% of the cost of qualifying heat pumps and heat pump water heaters, with an annual cap of $2,000, separate from the $1,200 general envelope cap.
IRC § 25D: Offers a 30% uncapped credit for geothermal heat pumps (ground-source), encouraging investment in renewable energy technologies.
Efficiency Standards: Equipment must meet the highest efficiency tier set by the Consortium for Energy Efficiency (CEE) or be recognized as ENERGY STAR Most Efficient to qualify for credits.
Form 5695: Taxpayers must claim these credits using IRS Form 5695 when filing their federal tax returns.
Idaho Considerations: While Idaho generally conforms to federal tax laws, it's essential to verify any state-specific implications with a local CPA.

Next Steps: Applying for Idaho Heat Pump Incentives

1. Start with Your Utility

Contact your electric utility before purchasing equipment. Rebate programs may require pre-approval or pre-inspection; installing equipment before applying can lead to disqualification. Confirm approved equipment models and required application documentation.

2. Get a Home Energy Audit

Idaho Power's $99 audit (or $149 for mixed-fuel homes) is a practical starting point for Idaho Power customers. An audit helps determine if a heat pump is the highest-value upgrade or if air sealing and insulation should be prioritized. The IRS §25C credit also covers $150 of a qualifying home energy audit's cost, partially offsetting the fee.

3. Confirm Equipment Eligibility Before Purchase

For the federal §25C credit, request the AHRI certificate from your contractor and confirm the unit meets CEE highest efficiency tier or ENERGY STAR Most Efficient requirements. For the Idaho state deduction, confirm with the Idaho Tax Commission that your specific system type qualifies. Do not assume air-source heat pumps automatically qualify for the geothermal-focused state deduction without direct verification.

4. Document Everything

Keep records for at least three years after filing:

Itemized contractor invoice detailing equipment model numbers and installation costs.
AHRI certificate from the manufacturer.
ENERGY STAR certification documentation.
Utility rebate approval letters and payment confirmations.
Receipts for any permit fees.

5. Consult a Tax Professional

The interaction of the federal §25C credit, the Idaho state deduction, and utility rebates that reduce your cost basis can be complex. A qualified tax professional familiar with Idaho returns can help sequence deductions, determine state deduction eligibility, and advise on splitting large projects across tax years.

6. Monitor the OEMR Loan Program

If you need financing and the OEMR State Energy Loan Program fits your project, check oemr.idaho.gov/loan-program/ regularly. The program is expected to reopen Summer 2025, but no specific date is confirmed. Regular monitoring can help you anticipate the application window.
