Heat Pump Tax Credit 2026: How to Claim the 25C Federal Credit
What Is the Heat Pump Tax Credit?
The federal heat pump tax credit is part of the Energy Efficient Home Improvement Credit under Section 25C of the Internal Revenue Code, extended and expanded by the Inflation Reduction Act (IRA). It provides a 30% tax credit on the cost of qualified heat pumps, including equipment and installation labor, up to a maximum of $2,000 per year.
This is a tax credit, not a deduction — it reduces your tax bill dollar for dollar. If you owe $5,000 in federal taxes and claim a $2,000 heat pump credit, you pay $3,000. However, it is nonrefundable: if you owe less than $2,000 in taxes, you cannot get the excess back as a refund.
Which Heat Pumps Qualify in 2026?
To qualify for the full $2,000 credit, your heat pump must meet the highest efficiency tier established by the Consortium for Energy Efficiency (CEE). For 2026, the requirements are:
| Heat Pump Type | Efficiency Requirement | Max Credit |
|---|---|---|
| Air-source heat pump (split system) | CEE Highest Tier (SEER2 16+, HSPF2 9.5+, EER2 12+) | $2,000 |
| Air-source heat pump (packaged) | CEE Highest Tier (SEER2 15+, HSPF2 8.5+) | $2,000 |
| Mini-split / ductless heat pump | CEE Highest Tier (SEER2 16+, HSPF2 9.5+) | $2,000 |
| Geothermal heat pump | ENERGY STAR certified | 30% (no cap)* |
| Heat pump water heater | UEF 2.2+ (ENERGY STAR Most Efficient) | $2,000 |
*Geothermal heat pumps qualify under Section 25D (Residential Clean Energy Credit), which has no annual dollar cap — you get 30% of total costs.
How to Claim the Credit: Step by Step
- Purchase and install a qualifying heat pump in your primary residence during tax year 2026
- Get the Manufacturer's Certification Statement — your installer or manufacturer provides this document confirming the equipment meets efficiency requirements
- Keep all receipts — equipment cost, labor cost, and any related electrical or ductwork modifications
- File IRS Form 5695 (Residential Energy Credits) with your 2026 tax return
- Enter the credit amount on Schedule 3 (Form 1040), line 5
You do not need to submit receipts with your return, but keep them for at least 3 years in case of an IRS audit. The manufacturer certification statement is the critical document — without it, the IRS can disallow the credit.
Stacking the Tax Credit with Rebates
The 25C tax credit stacks with both federal HEAR/HOMES rebates and state/utility incentives. Here is how a typical heat pump installation might pencil out:
| Incentive | Amount | Type |
|---|---|---|
| Heat pump installed cost | $12,000 | — |
| Federal 25C tax credit (30%) | -$2,000 | Tax credit (annual cap) |
| HEAR point-of-sale rebate | -$8,000* | Upfront rebate |
| Utility rebate | -$500 to -$2,000 | Varies by utility |
| Your net cost | $0 to $1,500 | — |
*HEAR rebate amount depends on household income. Low/moderate-income households (under 80% AMI) qualify for 100% of costs up to $8,000. Moderate-income households (80-150% AMI) get 50% up to $8,000. Above 150% AMI: not eligible for HEAR.

Common Mistakes That Cost You Money
- Buying a heat pump that does not meet CEE Highest Tier — many ENERGY STAR models qualify for utility rebates but not the full $2,000 25C credit. Check the AHRI directory before purchasing.
- Installing in a rental property — Section 25C only applies to your primary residence. Landlords should look at Section 179D (commercial energy deduction) instead.
- Missing the annual cap reset — the $2,000 cap resets every tax year. If you install a heat pump in December 2026 and a heat pump water heater in January 2027, you can claim $2,000 for each in separate tax years.
- Not claiming related improvements — the same 25C credit covers insulation ($1,200 cap), windows ($600 cap), and electrical panel upgrades ($600 cap) in addition to the $2,000 heat pump cap. These are separate annual limits.
Heat Pump Tax Credit vs Rebate: Key Differences
| Feature | 25C Tax Credit | HEAR Rebate |
|---|---|---|
| When you get money | When you file taxes (April 2027) | Point of sale (instant discount) |
| Income limits | None | Under 150% AMI |
| Amount | 30%, max $2,000/year | Up to $8,000 |
| Refundable? | No (reduces tax owed only) | Yes (direct payment) |
| Can you claim both? | Yes — they are designed to stack | |
Will the Heat Pump Tax Credit Continue After 2032?
The IRA extended the 25C credit through December 31, 2032. After that date, the credit expires unless Congress renews it. There is no phase-down schedule — the credit remains at 30% through 2032 and then drops to zero. If you are planning a heat pump installation, there is no advantage to waiting. Equipment prices are stable, and the credit amount will not increase.
