# IRA Heat Pump Tax Credit Explained: 2026 Guide
The Inflation Reduction Act (IRA) heat pump tax credit, officially known as the Energy Efficient Home Improvement Credit (25C), allows US homeowners to claim up to $2,000 annually for qualifying heat pump installations through 2032. In 2026, the credit covers 30% of the total cost, with a maximum of $2,000 per year, and applies to heat pumps that meet specific efficiency standards set by the Department of Energy. There are no income limits to claim this credit, and it can be combined with state and utility rebates for additional savings.
The IRA heat pump tax credit is a federal tax incentive created by the Inflation Reduction Act of 2022, which expanded and extended the existing Nonbusiness Energy Property Credit (25C). Starting January 1, 2023, the credit was increased from a lifetime cap of $500 to an annual limit of $2,000 per year for heat pumps specifically. This change made heat pumps one of the most generously incentivized home energy upgrades under the law.
The credit is non-refundable, meaning it can reduce your tax liability to zero but won't result in a refund if the credit exceeds what you owe. However, you can carry forward unused portions of the credit to future tax years, which is a significant advantage over many other non-refundable credits. According to the IRS, the credit applies to installations placed in service between January 1, 2023, and December 31, 2032.
For 2026, the heat pump tax credit remains at 30% of the total installed cost, capped at $2,000 per year. This is the same structure that took effect in 2023 and will continue through 2032. Here's the breakdown:
A 2024 analysis by the Department of Energy found that the average installed cost of a qualifying heat pump system in the US is approximately $5,800, which would yield a credit of $1,740—just under the $2,000 cap. For more expensive systems, such as cold-climate heat pumps that can cost $8,000–$12,000 installed, the $2,000 cap applies at $6,667 in qualifying costs.
Unlike some IRA provisions that phase down after 2032, the heat pump tax credit remains at 30% through the end of 2032. After that, the credit reverts to its pre-IRA structure unless Congress extends it. A 2023 report from the Bipartisan Policy Center noted that the credit's extension through 2032 was designed to give homeowners a predictable, long-term incentive to adopt heat pump technology.
Not all heat pumps qualify. To be eligible, the heat pump must meet specific efficiency standards set by the Department of Energy and the IRS. The requirements differ slightly depending on whether you're installing an air-source heat pump (which transfers heat between your home and the outside air) or a geothermal heat pump (which uses the ground's stable temperature).
For air-source heat pumps installed in 2026, the equipment must meet the following efficiency thresholds:
These standards are higher than the minimum federal efficiency standards. As of 2026, the federal minimum for SEER2 is 15.0 for the northern US and 16.0 for the southern US, so qualifying units must be at least one tier above the baseline. According to the Air-Conditioning, Heating, and Refrigeration Institute (AHRI), approximately 65% of residential heat pump models on the market in 2025 met the IRA's efficiency thresholds.
Geothermal (ground-source) heat pumps have separate, higher efficiency requirements:
Geothermal systems are typically more expensive ($15,000–$30,000 installed) but also qualify for a separate 30% federal tax credit under Section 25D, which has no dollar cap. This is a different credit from the heat pump tax credit (25C), and you cannot claim both for the same system.
The easiest way to confirm eligibility is to check the product's Energy Star certification. Most qualifying heat pumps will have the Energy Star Most Efficient label for 2026. You can also search the AHRI directory using the model number to find the efficiency ratings. The IRS requires that the manufacturer provide a certification statement with the product, and you should keep this documentation with your tax records.
There are no income limits for the IRA heat pump tax credit. This is a critical distinction from the IRA's point-of-sale rebate programs (such as the Home Efficiency Rebates and the Electrification Rebates), which are income-qualified and administered through state energy offices.
The heat pump tax credit is available to any US taxpayer who owns a home and installs qualifying equipment in that home. Renters cannot claim the credit unless they own the heat pump system themselves (which is rare). Landlords can claim the credit for qualifying installations in rental properties they own, provided the property is their primary residence or a rental unit they occupy part-time.
A 2024 survey by the National Association of Realtors found that 72% of homebuyers considered energy efficiency a "very important" factor in their purchase decision, and the lack of income caps on the tax credit makes it accessible to a broad range of homeowners.
Yes, you can combine the federal heat pump tax credit with state and utility rebates, as long as you don't claim the same expense under two federal programs. This stacking can significantly reduce your out-of-pocket costs.
The IRS allows you to claim the tax credit on the net cost after state and utility rebates, but only if those rebates are not treated as taxable income. Most state and utility rebates are not taxable, so you can subtract them from the total cost before calculating your 30% credit. However, if a rebate is treated as taxable income (which is rare for home energy rebates), you must include it in your gross income and claim the credit on the full cost.
Here's an example: You install a $6,000 heat pump system. Your state offers a $1,000 rebate, and your utility offers a $500 rebate. Your net cost is $4,500. You can claim 30% of $4,500 = $1,350 as your federal tax credit. Total savings: $2,850 off the original $6,000 cost.
You cannot claim both the heat pump tax credit (25C) and the Residential Clean Energy Credit (25D) for the same heat pump system. The 25D credit applies to solar panels, solar water heaters, geothermal heat pumps, and battery storage. If you install a geothermal heat pump, you must choose between the 25C credit (30% up to $2,000) and the 25D credit (30% with no dollar cap). For geothermal systems, the 25D credit is almost always more valuable because it has no cap.
You also cannot claim the heat pump tax credit for a system that was financed through a federal grant or subsidized loan that covers the entire cost, as the IRS considers that a double benefit.
Claiming the credit requires filing IRS Form 5695 (Residential Energy Credits) with your annual tax return. Here's the step-by-step process:
Before filing, collect the following:
Part II of Form 5695 is where you calculate the Energy Efficient Home Improvement Credit. You'll enter:
The form also asks for the total cost of all qualifying improvements (windows, doors, insulation, etc.), which are subject to different caps. For 2026, the overall cap for all improvements combined is $1,200 per year, except for heat pumps, heat pump water heaters, and biomass stoves, which have separate $2,000 caps.
Attach Form 5695 to your Form 1040. The credit is non-refundable, so it will reduce your tax liability but not below zero. If your tax liability is less than the credit amount, you can carry the unused portion forward to the next tax year.
To make this concrete, here are three real-world scenarios based on typical installations:
A homeowner in Ohio replaces their 20-year-old central AC and furnace with a qualifying 3-ton air-source heat pump. Total installed cost: $7,200. The state offers a $500 rebate. Net cost: $6,700. The 30% credit is $2,010, but capped at $2,000. Total savings: $2,500 ($500 rebate + $2,000 tax credit). The homeowner's effective cost: $4,700.
A homeowner in California adds a 3-zone ductless mini-split system to heat and cool an addition. Total installed cost: $5,400. No state rebate available, but the utility offers $300. Net cost: $5,100. The 30% credit is $1,530. Total savings: $1,830. Effective cost: $3,570.
A homeowner in Minnesota installs a geothermal heat pump system for $22,000. They choose the 25D credit (30% with no cap) instead of the 25C credit (30% capped at $2,000). Their credit is $6,600. They also receive a $2,000 state rebate. Total savings: $8,600. Effective cost: $13,400.
The IRA created two main types of incentives: tax credits (which you claim on your tax return) and rebates (which are administered by states and typically applied at the point of sale). The heat pump tax credit is the tax credit side. The rebate side includes:
These rebate programs are still rolling out. As of early 2026, approximately 35 states have launched their HEEHRA programs, according to the Department of Energy's Office of State and Community Energy Programs. The key difference: rebates are income-qualified (typically up to 150% of area median income), while the tax credit has no income limit.
Yes, but with a caveat. If you receive a federal rebate (from HOMES or HEEHRA), you must subtract that amount from the cost before calculating the tax credit. However, most state and utility rebates are not considered federal income, so they don't reduce the credit basis. The IRS clarified in Notice 2023-59 that rebates from state or local governments, utilities, or manufacturers are generally not included in income and do not reduce the credit basis, as long as they are not specifically designated as federal financial assistance.
The heat pump tax credit is stable through 2032, but there are a few things to watch:
No. The heat pump tax credit is a non-refundable credit, not a deduction. You can claim it even if you take the standard deduction. You simply need to file Form 5695 with your tax return.
No. The credit is only available for existing homes that are your primary residence. New construction does not qualify. The IRS defines "existing home" as one that has been occupied for at least one year prior to the installation.
You can still claim the credit, but only for the cost of the equipment, not for the value of your own labor. If you hire a contractor, both equipment and installation labor qualify. If you do it yourself, only the equipment cost counts.
No. The credit applies to any qualifying heat pump installation, including supplemental systems like ductless mini-splits. However, the system must be used for both heating and cooling to qualify—a heat pump used only for cooling (essentially an air conditioner) does not qualify.
Yes, but heat pump water heaters fall under a separate category with a different cap. They qualify for the same 30% credit, but the annual cap is $2,000 for heat pump water heaters specifically. This is separate from the $2,000 cap for heat pumps used for space heating and cooling.
You can carry forward the unused portion of the credit to the next tax year. However, you cannot carry it forward beyond one year. If you cannot use the full credit in the year of installation and the following year, the remainder is forfeited.
Before you buy a heat pump, get a written estimate from at least two licensed HVAC contractors that includes the model numbers and efficiency ratings. Confirm the equipment meets the IRA's SEER2, EER2, and HSPF2 thresholds. Then, check your state's energy office website for available rebates—many states offer $500–$2,000 in additional incentives. Keep all documentation, including the manufacturer's certification and your contractor's invoice, in a dedicated folder. When you file your 2026 taxes, use Form 5695 to claim your credit. The entire process, from installation to tax filing, can save you $2,000 or more on a single heat pump upgrade.
