If you installed a heat pump in 2025, you can claim the full heat pump tax credit 2026 on your federal return, up to $2,000, but only if your system hits the right efficiency numbers and your paperwork is ready.
The credit doesn’t come automatically. Your installer doesn’t file it. The IRS doesn’t notify you. You claim it on your 2025 return using Form 5695, and if your heat pump doesn’t meet the specific CEE efficiency threshold required, you get nothing — regardless of what the contractor told you. I’ve seen this catch homeowners off guard more than any other part of the process.
This guide covers exactly how the credit works, which systems qualify, and how to claim the full $2,000 without a rejected return. If you installed in 2026, there’s a section at the bottom for you. The credit situation changed, but you’re not necessarily out of options.
This article explains how the heat pump tax credit works based on IRS rules and IRA legislation. It is not tax advice. For your specific situation (especially if you have low tax liability, took other energy credits, or installed in a rental) talk to a CPA or enrolled agent before filing. Last reviewed: March 2026 — tax rules change, verify current guidance at IRS.gov before filing.

Is the Heat Pump Tax Credit Still Available in 2026?
Yes, for heat pumps installed in 2025. The heat pump tax credit 2026 is claimed on your 2025 return and is part of the Energy Efficient Home Improvement Credit (Section 25C) under the Inflation Reduction Act. For 2025 returns filed in 2026, the credit remains at its full amount.
The key boundary that trips people up: the credit applies to the year you had the system installed and placed in service, not the year you file. If your heat pump was installed in 2025, you claim it on your 2025 return, which you’re filing right now. If it was installed in 2024, you would have claimed it on your 2024 return.
How Much Can You Claim? (The $2,000 Breakdown)
The heat pump federal tax credit is 30% of the cost of a qualifying system, capped at $2,000 per year. That $2,000 cap is separate from the $1,200 annual cap that covers other Section 25C improvements — insulation, windows, doors, and heat pump water heaters.
To claim the full $2,000, your total installed project cost needs to be at least $6,667. Heat pump installations typically run $8,000–$15,000, so most homeowners hit the cap easily.
| Project cost (installed) | 30% of cost | Actual credit (capped at $2,000) |
|---|---|---|
| $4,000 | $1,200 | $1,200 |
| $6,000 | $1,800 | $1,800 |
| $6,667 | $2,000 | $2,000 |
| $10,000 | $3,000 | $2,000 (capped) |
| $15,000 | $4,500 | $2,000 (capped) |
The cost basis includes both equipment and labor. Keep your contractor invoice, as the IRS can ask you to substantiate the amount you claim.
The non-refundable catch — and why it matters
This credit is non-refundable. That’s not just a technicality. It’s the single most misunderstood thing about it.
Non-refundable means the credit can only reduce your federal tax liability to zero. It can’t produce a refund beyond what you already overpaid in withholding. If you owe $800 in federal income tax before the credit, you get $800 back, not $2,000.
Most homeowners with standard income will have enough federal tax liability to absorb the full $2,000. But if you had a low-income year, large deductions, or other credits already reducing your liability, run your numbers before assuming you’ll get the maximum. Use the estimator below to see what that means for your specific numbers.

Which Heat Pumps Qualify? (CEE Tiers, Mini-Splits, and the Efficiency Trap)
Not every heat pump qualifies. This is where a lot of homeowners get burned: they installed a system they assumed was eligible, and it isn’t.
The IRS requires qualifying systems to meet efficiency levels defined by the Consortium for Energy Efficiency (CEE). “ENERGY STAR certified” is necessary but not sufficient. The system must meet the CEE highest efficiency tier for its equipment type.
| Equipment type | Minimum efficiency for credit |
|---|---|
| Air-source split system (heating + cooling) | SEER2 ≥ 15.2, EER2 ≥ 10, HSPF2 ≥ 7.8 |
| Air-source packaged unit (heating + cooling) | SEER2 ≥ 15.2, EER2 ≥ 10, HSPF2 ≥ 6.4 |
| Ductless mini-split | SEER2 ≥ 16, HSPF2 ≥ 9.0 (matched system — both indoor + outdoor units) |
| Geothermal / ground-source heat pump | Covered under Section 25D (separate from 25C) — but Section 25D was also repealed for 2026+ installs. Verify current status at IRS.gov before filing. |
For mini-splits: both the indoor and outdoor units must meet the CEE tier together as a matched system. An outdoor unit that qualifies on its own doesn’t guarantee the combined system qualifies. Verify the specific model pair before claiming.
What about heat pump water heaters?
Heat pump water heaters qualify under Section 25C but under a different sub-limit — they fall under the $1,200 cap, not the $2,000 heat pump cap. If you installed both a heat pump and a heat pump water heater in 2025, you can potentially claim up to $3,200 total — subject to your tax liability.
Do You Qualify? (Eligibility Rules + Non-Refundable Check)
The eligibility rules for the heat pump tax credit 2026 filing are clear-cut for most homeowners:
- Primary residence only. The heat pump must be in a home you use as your primary residence. Rental properties and vacation homes don’t qualify. Note: you don’t have to own the home — renters can claim the credit for a qualifying heat pump installed in their primary residence, as long as they bear the cost of installation.
- Existing home only. New construction is excluded from Section 25C. If you built a new home in 2025 and installed a heat pump, that installation doesn’t qualify here.
- Installed and placed in service in 2025. The system must have been fully operational in 2025 — not just purchased or contracted.
- No income limit. Unlike some federal programs, Section 25C has no income ceiling. High earners qualify as long as they have federal tax liability.
- Must have federal tax liability. Because the credit is non-refundable, you need to owe federal income tax to benefit.
How to Claim It: Form 5695 Step-by-Step
How to complete Form 5695 (Part II)
File IRS Form 5695 (Residential Energy Credits) with your federal return. You’ll complete Part II for the Section 25C Energy Efficient Home Improvement Credit.
What to have ready before you file
- Manufacturer’s certification statement (confirming your model meets qualifying efficiency standards — your installer or manufacturer provides this)
- Installation invoice showing equipment and labor costs
- Qualified Manufacturer Identification Number (QMID) — see below
- Date installation was placed in service
- IRS Form 5695 (fillable PDF) — download and review before your tax software session
The QMID: what it is and why you need it
Starting with 2025 returns, the IRS requires a Qualified Manufacturer Identification Number (QMID) for most energy efficiency credits, including heat pumps. This is a unique number assigned by the manufacturer when a product is registered as qualifying for the credit.
You should have received it from your installer or directly from the manufacturer. If you didn’t, contact the manufacturer’s customer support with your model number — most respond within a few business days, though response times vary a lot by brand. Some manufacturers list QMIDs on their websites by model. A missing or wrong QMID is one of the most common reasons returns get flagged, so track it down before you file.
If you can’t locate a QMID, contact your installer or the manufacturer directly before filing — most respond within a few business days. Keep any manufacturer certification documents with your tax records as supporting documentation while you track down the QMID.
Form 5695 walkthrough (Part II)
- Line 19a: Check the box for “Heat pump” (or “Heat pump for space heating or cooling”)
- Line 19b: Enter qualifying cost — equipment plus labor
- Lines 20–25: Follow the form instructions to calculate 30% of costs. The form walks you through the $1,200 and $2,000 caps separately.
- QMID field: Enter the manufacturer’s QMID for your specific model
- Transfer to Schedule 3: The credit flows to Schedule 3, Line 5b, then to your Form 1040
Can You Stack a Tax Credit With a State Rebate?
Yes, and this is where the real savings stack up. Federal tax credits and state rebate programs are separate and can generally be combined. For the heat pump tax credit 2026, the key rule is: you must reduce your credit basis by any rebate received.
If you received a heat pump rebate from your state or utility and also installed a qualifying system, you can claim both — but the rebate comes off your cost basis first. If you installed a $10,000 heat pump and received a $1,500 state rebate, your basis for the federal credit calculation is $8,500. Your credit is 30% of $8,500 = $2,550, still capped at $2,000.
| Scenario | System cost | State rebate | Adjusted basis | Federal credit (30%, capped) | Total saved |
|---|---|---|---|---|---|
| No rebate | $10,000 | $0 | $10,000 | $2,000 | $2,000 |
| State rebate | $10,000 | $1,500 | $8,500 | $2,000 | $3,500 |
| Large rebate | $10,000 | $4,000 | $6,000 | $1,800 | $5,800 |
Many utilities in the Northeast, Pacific Northwest, and upper Midwest offer $500–$1,500 for qualifying heat pump installs. Check your utility’s website and your state energy office — most of these programs run independently of federal legislation.
Installed in 2026? Here’s What You Can Still Get
The Section 25C heat pump tax credit expired on December 31, 2025. The One Big Beautiful Bill Act, signed into law on July 4, 2025 (Public Law 119-21), repealed the credit as part of a broader restructuring of the tax code. Heat pump installations completed in 2026 or later are not eligible for the federal Section 25C tax credit.
Geothermal heat pumps are on a separate track (Section 25D), but that credit was also repealed for expenditures after December 31, 2025. See IRS Publication 5967 for confirmation.
There’s no longer a federal heat pump rebate program available to everyone, but state and utility programs fill part of that gap. What’s still available for 2026 air-source heat pump installs:
- State rebate programs. These run independently of federal legislation and are now the primary source of incentive savings. Massachusetts (Mass Save) offers up to $8,500 for whole-home conversions. New York offers state tax credits up to 25%, capped at $5,000. Colorado, Maine, Vermont, and others have active programs. Check your state rebate program or the DSIRE database for your state’s current programs.
- Utility rebates. Many utilities offer $300–$1,500 per qualifying heat pump installation as point-of-sale or post-install rebates that don’t require tax liability. Check your utility’s website.
- HOMES / HEEHRA rebate programs. Some states are still disbursing IRA-funded Home Efficiency Rebates Program (HEEHR) funds, a direct rebate program separate from the now-expired tax credit. Income limits apply (up to 150% of area median income). Not all states have launched this; check your state energy office for availability.
Mistakes That Cost Homeowners the Credit
These are the most common reasons the credit gets missed or rejected:
- System doesn’t meet the CEE tier. Assuming ENERGY STAR certification is enough. It isn’t — verify against the CEE database before filing.
- Missing QMID. The IRS will flag returns without a valid QMID for 2025 installations. Get it from your installer or manufacturer before filing.
- Claiming on a rental or second home. Section 25C applies only to your primary residence.
- New construction. If the home was newly built in 2025, the credit doesn’t apply under Section 25C.
- Not reducing basis for rebates. Claiming the credit on the full pre-rebate cost when you received a state or utility rebate is an error.
- Assuming the credit carries forward. Unused Section 25C credit does not carry forward. What you can’t use this year is gone.
- Confusing property ownership with eligibility. You don’t have to own the home to claim the credit — renters can claim it too, as long as the home is their primary residence and they paid for the installation. But landlords can’t claim it on behalf of their tenants.
Before filing, make sure you have your QMID, installation invoice, and manufacturer certification statement ready — those are the three things that determine whether your claim goes through cleanly.
