Heat pump tax credit 2026 — IRC §25C, who qualifies, how to claim

The federal heat pump tax credit under IRC §25C (Inflation Reduction Act) covers 30% of the project cost, up to $2,000, for qualifying heat pump installations placed in service in your primary residence. The credit is nonrefundable but rolls forward; many homeowners stack it with state utility rebates for $3,000-$10,000 in combined incentives.

Who qualifies

All four must be true:

1. You own the home (renters can't claim — landlord claims).
2. Primary residence in the US. Vacation homes get a different, smaller credit.
3. Heat pump meets CEE-tier efficiency standards — most ENERGY STAR Cold Climate units qualify automatically.
4. Installed by a qualified contractor OR you have the AHRI certificate showing the matched indoor/outdoor pair.

What "CEE-tier efficiency" means in practice for 2026:

• Split-system air-source heat pump: SEER2 ≥ 16, EER2 ≥ 12, HSPF2 ≥ 9.
• Packaged air-source: SEER2 ≥ 15.2, EER2 ≥ 11.5, HSPF2 ≥ 8.1.
• Ductless mini-split: SEER2 ≥ 16, HSPF2 ≥ 9.
• Geothermal (ground-source): ENERGY STAR certified.

Most mid-tier installs from Mitsubishi (Hyper-Heat), Daikin (Aurora, Atmosphera), Bosch (IDS Premium), Carrier (Infinity), and Trane (XV20i) qualify out of the box.

How to claim

1. Save the AHRI certificate the contractor provides at install.
2. Save the itemized invoice (separate equipment vs labor lines).
3. On your federal return, file Form 5695 ("Residential Energy Credits") with the amount in the "Energy Efficient Home Improvement Credit" section.
4. The credit is nonrefundable but unused amount rolls forward to next year's return.

Stacking with state rebates

This is where the real value is. The federal credit is on top of state-level utility rebates, which average $500-$1,500 but go much higher in some states:

| State | Best stacked incentive | Source | | --- | --- | --- | | Massachusetts | $625-$10,000 via MassSave | MassSave | | New York | $1,000-$10,000 via NYSERDA Clean Heat | NYSERDA | | Maine | $1,200-$10,000 via Efficiency Maine | EM | | Connecticut | $625-$7,500 via Energize CT | Energize CT | | Vermont | $700-$10,000 via Efficiency Vermont | EV | | Rhode Island | $625-$10,000 via RI Energy | RI Energy | | New Hampshire | $750-$10,000 via NH Saves | NH Saves | | Minnesota | $400-$4,000 via Xcel + state program | Xcel MN | | Illinois | $250-$1,800 via ComEd / Ameren | Utility | | California | $1,000-$3,000 via TECH Clean California | TECH CA |

For a $14,000 air-source heat pump install in Massachusetts: $2,000 federal + $625-$10,000 state = $2,625-$12,000 in combined incentives, net cost as low as $2,000-$11,000.

Income limits

There are no income limits on the federal §25C credit through 2032. Separate HEEHRA point-of-sale rebates (the other Inflation Reduction Act program) do have income limits (≤150% AMI), but that's a different program from this credit.

What does NOT qualify

• Replacement of a working heat pump with a slightly newer model — only "new HVAC system" installs.
• Repair work or part replacement.
• DIY installs without contractor-provided AHRI certificate.
• Equipment-only purchases at retail (must be installed in your home, not "ready to install").

Watch out for

• Contractors marking up equipment to capture more credit. The credit is 30% of project cost capped at $2,000. If they raise labor to inflate the percentage, the IRS audit risk falls on you.
• Vacation home installs. Different, smaller credit applies.
• State rebate timing. Some states require pre-approval before install; others let you claim after. Check before signing.

The federal credit alone is rarely the deciding factor — it's the stacked utility + state rebates that move the math. Check your state program first; if it's generous, the federal $2k becomes the bonus rather than the headline.
