Federal Heat Pump Tax Credit Expired: Why Massachusetts Homeowners Still Win in 2026
The $2,000 Section 25C heat pump tax credit ended December 31, 2025 under OBBBA. But Massachusetts has the strongest state-level heat pump incentive stack in the nation — Mass Save rebates up to $8,500, a 0% HEAT Loan, and seasonal electric rate discounts make heat pumps a smart investment even without federal help.
TL;DR — The Tax Credit Is Gone, But MA Incentives Are Strong
- Gone: $2,000/year federal 25C heat pump tax credit (expired Dec 31, 2025 under OBBBA)
- Gone: $600/year 25C insulation credit, $150 home energy audit credit
- Still active: Mass Save whole-home ASHP rebate: $2,650/ton (max $8,500)
- Still active: 0% HEAT Loan up to $25,000 (up to 10-year term)
- Still active: Seasonal heat pump electric rate discount (~$200-$250/winter)
- Market factor: MA natural gas rates up 13% since 2024, making heat pumps more competitive
What Happened: The 25C Credit Is Terminated
The Inflation Reduction Act (IRA) of 2022 expanded and extended the Section 25C Energy Efficient Home Improvement Credit, providing homeowners with annual tax credits for energy-efficient upgrades. The most valuable sub-category was the heat pump credit: up to $2,000 per year for qualifying air source heat pumps, ground source heat pumps, and heat pump water heaters. The credit also included $600/year for insulation and air sealing, $600/year for windows and doors, and $150 for home energy audits.
The One Big Beautiful Bill Act (OBBBA), signed into law in 2025, terminated the Section 25C credit as part of broader changes to the tax code. The credit expired for all expenditures incurred after December 31, 2025. There is no phase-out or reduced rate — the credit is simply gone.
What was lost — Section 25C credits terminated by OBBBA:
All amounts shown are the maximum annual credits that were available under Section 25C. The aggregate annual limit was $3,200.
For a Massachusetts homeowner installing a whole-home heat pump system, the practical impact is a $2,000 loss compared to 2025. A homeowner who installed a $15,000 heat pump system in December 2025 could claim $2,000 on their 2025 tax return. The same installation in January 2026 receives $0 in federal tax credits.
This is painful. But the story in Massachusetts is very different from most other states, because the Bay State has the most generous state-level heat pump incentive stack in the country. Let's look at what remains.
Massachusetts Incentives That Remain (and They're Strong)
Massachusetts homeowners benefit from a state-funded incentive ecosystem that operates independently of the federal tax code. These programs are funded through utility ratepayer surcharges and administered by Mass Save (the statewide efficiency program run by Eversource, National Grid, Unitil, Berkshire Gas, Liberty Utilities, and Cape Light Compact). None of these programs were affected by the OBBBA.

Eversource and National Grid offer a reduced electric supply rate during the winter heating season (November through March) for homes with qualifying heat pump systems. The discount applies to your entire home electric usage, not just the heat pump. This ongoing annual savings helps offset the loss of the one-time federal tax credit over time. Savings vary by usage but average approximately $40-$50/month during winter months for typical all-electric homes.
Why Heat Pumps Still Make Financial Sense in 2026
The loss of the $2,000 federal credit is a setback, but several market forces are actually improving heat pump economics in Massachusetts in 2026:
Natural gas rates are rising
Massachusetts residential natural gas rates have increased approximately 13% since 2024, driven by pipeline constraints, LNG export demand, and carbon pricing under the Transportation and Climate Initiative. The average residential gas rate in eastern MA is now approximately $2.10/therm (including delivery charges). Each 10% gas rate increase makes heat pumps more competitive, as the fuel cost savings grow larger.
Heat pump efficiency exceeds 300% COP
Modern cold-climate heat pumps (Mitsubishi Hyper-Heating, Fujitsu XLTH, Daikin Aurora) deliver 300-400% COP (Coefficient of Performance) even at temperatures below 5 degrees F. That means for every dollar of electricity consumed, the heat pump delivers $3-$4 worth of heating. A gas furnace at 95% AFUE delivers $0.95 of heat per dollar of gas. At current MA rates, the operating cost per BTU is comparable, and heat pumps also provide air conditioning — a dual benefit gas furnaces cannot match.
Equipment costs are falling
Heat pump equipment costs have decreased approximately 8-12% since 2023 due to increased manufacturing capacity, competition from new market entrants, and economies of scale. A whole-home mini-split system that cost $18,000-$22,000 installed in 2023 now runs $15,000-$19,000 in 2026. This price reduction partially offsets the lost federal credit.
Dual function: heating AND cooling
A heat pump replaces both your furnace/boiler AND your air conditioner. If you would otherwise need a new central AC system ($4,000-$7,000), the effective incremental cost of the heat pump is much lower. Massachusetts summers are getting hotter — 2025 had the warmest July on record in Boston. The cooling value of a heat pump is increasingly important.
2025 vs. 2026 Heat Pump Incentive Stack
Here is a side-by-side comparison of the total incentive stack for a whole-home heat pump installation in Massachusetts — a typical 3-ton system installed in a single-family home replacing a gas furnace:
2025 Incentive Stack
2026 Incentive Stack
Bottom line: The net upfront cost increased by $1,500 ($7,550 vs $6,050) due to losing the federal credit. But annual operating savings are higher in 2026 ($900-$1,500/yr vs $800-$1,400/yr) because gas prices have risen and equipment costs have fallen. The payback period extends from approximately 4.3-7.6 years in 2025 to 5.0-8.4 years in 2026 — still well within the 15-20 year lifespan of a modern heat pump. And you get free air conditioning.
Remaining Federal Credits for Heat Pumps: None for Residential
We want to be completely transparent: there are no federal tax credits available for residential heat pump installations in 2026. Some contractors may incorrectly reference outdated information or confuse residential and commercial credits. Here is the complete picture:
Residential: No Federal Credits
- Section 25C: Terminated by OBBBA. No heat pump credit, no insulation credit, no energy audit credit.
- Section 25D: Also expired Dec 31, 2025. This was the residential clean energy credit (solar, battery, geothermal). It does not apply to air source heat pumps.
- HOMES/HEEHRA: IRA point-of-sale rebate funding was rescinded before Massachusetts could fully deploy the program.
Commercial: Limited Options May Apply
- Section 179D: The Energy Efficient Commercial Building Deduction may still be available for commercial buildings that install qualifying HVAC systems including heat pumps. Provides a tax deduction (not credit) of up to $5.00/sq ft. Consult a tax professional.
- Section 48/48E: Applies to geothermal heat pumps in commercial settings (not air source). Projects must begin construction before certain deadlines. Consult a tax professional.
Beware of contractors claiming federal credits are still available
If a contractor quotes you a price that includes a “federal tax credit” or “IRA rebate” for a residential heat pump installation in 2026, that is incorrect. Ask for an updated quote that reflects the actual incentive landscape. Mass Save rebates and the HEAT Loan are real and substantial — there is no need to inflate savings with nonexistent federal programs.
Heat Pump vs. Oil and Propane: Even Stronger Case in 2026
While the gas-to-heat-pump economics are favorable, the case for heat pumps is even stronger for Massachusetts homes heating with oil or propane. These fuel prices are substantially higher than natural gas and more volatile:
| Fuel Source | Avg Annual Cost (MA) | Heat Pump Savings | Payback (After Rebate) |
|---|---|---|---|
| Heating Oil | $2,800-$3,600/yr | $1,200-$2,000/yr | 3.8-6.3 years |
| Propane | $3,000-$4,200/yr | $1,400-$2,600/yr | 2.9-5.4 years |
| Natural Gas | $1,800-$2,600/yr | $600-$1,200/yr | 6.3-12.6 years |
| Electric Baseboard | $3,200-$4,800/yr | $1,800-$3,000/yr | 2.5-4.2 years |
Savings estimates assume a 2,000 sq ft home, 3-ton heat pump with 3.5 COP average seasonal efficiency, Eversource electric rates with seasonal discount, and 2026 fuel prices. Payback calculated on net cost of $7,550 after Mass Save whole-home rebate.
For homes heating with oil or propane — which includes roughly 30% of Massachusetts single-family homes — the heat pump investment pays back in under 6 years in most cases, even without the federal credit. For homes with electric baseboard heat, the payback can be under 3 years. These are strong returns that any homeowner would accept.
Frequently Asked Questions
Is the federal $2,000 heat pump tax credit really gone?
Yes. The Section 25C Energy Efficient Home Improvement Credit, which provided up to $2,000/year for qualifying heat pump installations, was terminated by the One Big Beautiful Bill Act (OBBBA) signed into law in 2025. The credit expired for all expenditures after December 31, 2025. There is no federal tax credit available for residential heat pump installations in 2026. This also affects the $600 credit for insulation, the $150 credit for home energy audits, and other 25C sub-categories.
What Mass Save heat pump rebates are still available in 2026?
Mass Save rebates remain fully funded and substantial. For whole-home air source heat pumps (replacing your primary heating system), the rebate is $2,650 per ton of installed capacity, up to $8,500 maximum. For partial-home heat pumps (supplementing existing heating), the rebate is $1,125 per ton, up to $8,500. Income-eligible households can receive enhanced rebates and additional support. These rebates are funded by ratepayers through Eversource, National Grid, and Unitil — they are not federal programs and are unaffected by the OBBBA.
Is the 0% HEAT Loan still available?
Yes. The Mass Save HEAT Loan program continues to offer 0% interest financing up to $25,000 for qualifying heat pump installations (and other eligible energy efficiency improvements). The loan term is up to 7 years for standard improvements and up to 10 years for heat pump installations. This is a state program administered through participating local lenders and is not affected by the federal tax credit expiration. You can combine the HEAT Loan with Mass Save rebates.
Does the seasonal heat pump electric rate still apply in 2026?
Yes. The Massachusetts seasonal heat pump electric rate discount remains in effect. Eversource and National Grid offer reduced electric rates during the heating season (November-March) for homes with qualifying heat pump systems. This discount typically saves $40-$50 per month during winter months, or approximately $200-$250 per heating season. The rate applies to your entire home electric usage, not just the heat pump, making it especially valuable for homes that have already electrified other appliances.
Are heat pumps still worth it in Massachusetts without the federal tax credit?
Yes, for most Massachusetts homeowners. Even without the $2,000 federal credit, the combination of Mass Save rebates ($2,650-$8,500), the 0% HEAT Loan ($25,000), the seasonal electric rate discount (~$200-$250/year), and rising natural gas rates (up 13% since 2024) makes heat pumps financially competitive with gas furnaces over a 10-15 year period. Heat pumps also provide air conditioning — eliminating the need for a separate AC system. For homes currently heating with oil or propane, the economics are even stronger due to higher fuel costs.
Are there any remaining federal credits for heat pumps in 2026?
For residential homeowners, no. The Section 25C credit is completely terminated. For commercial buildings, the Section 179D Energy Efficient Commercial Building Deduction may still apply in some cases for qualifying HVAC improvements, including commercial-scale heat pump installations. The 179D deduction allows a tax deduction (not a credit) of up to $5.00 per square foot for qualifying energy-efficient building improvements. Consult a tax professional for commercial applicability.
What about the Inflation Reduction Act rebates (HOMES and HEEHRA)?
The HOMES (Home Efficiency Rebates) and HEEHRA (Home Electrification and Appliance Rebates) programs, which were part of the IRA, were also affected by the OBBBA. Massachusetts had not fully launched its HEEHRA point-of-sale rebate program before the federal funding was rescinded. Mass Save rebates, which are state-funded and were already more generous than the proposed HEEHRA amounts for heat pumps, continue to serve as the primary rebate mechanism for Massachusetts homeowners.
Should I wait for a new federal heat pump incentive?
We do not recommend waiting. There is no pending legislation to restore heat pump tax credits, and the political landscape makes reinstatement unlikely in the near term. Meanwhile, Mass Save rebates could be adjusted in future program years, natural gas prices continue to rise, and your old heating system continues to cost you money. The current Massachusetts incentive stack — Mass Save rebates + HEAT Loan + seasonal electric rate — provides a strong economic case for installing a heat pump in 2026.
