If you were counting on a federal tax credit to offset the cost of a new water heater in 2026, you need to know this upfront: the credit is gone. The Section 25C energy efficiency tax credit — which covered 30% of the cost of qualifying heat pump water heaters up to $2,000 — expired December 31, 2025. No federal water heater tax credit exists for installations made in 2026.
That said, you are not out of luck. State rebate programs, utility company incentives, and income-qualified assistance programs can still put hundreds — or even thousands — of dollars back in your pocket. This guide explains exactly what expired, why it happened, and what savings remain available for 2026 buyers.
What Was the Federal Water Heater Tax Credit?
The federal credit came from the Inflation Reduction Act (IRA) of 2022, specifically under Internal Revenue Code Section 25C. For qualifying heat pump water heaters, homeowners could claim 30% of the purchase and installation cost, up to a $2,000 annual cap per year. A homeowner who replaced a unit in 2023, 2024, or 2025 could claim up to $2,000 on each of those tax returns.
To qualify under 25C, heat pump water heaters had to meet the Consortium for Energy Efficiency (CEE) Tier 3 or higher standard — generally a Uniform Energy Factor (UEF) of 2.0 or higher. Standard tank water heaters, tankless gas heaters, and most conventional electric heaters did not qualify. The credit was non-refundable, meaning it reduced your tax liability dollar-for-dollar but did not generate a refund if it exceeded what you owed.

Why Did the Federal Credit Expire?
The Section 25C credit was part of a broader package of energy incentives tied to the Inflation Reduction Act. In 2025, Congress passed the One Big Beautiful Bill Act, which restructured federal energy spending priorities and allowed the residential energy efficiency credits — including 25C — to expire at the end of 2025 as originally scheduled under the IRA transition provisions.
The IRA had originally extended and expanded 25C credits from 2022 through the end of 2032, but subsequent budget reconciliation reduced the effective window. The result: December 31, 2025 became the hard cutoff. Installations completed on or after January 1, 2026 do not qualify for the federal credit, regardless of when the water heater was purchased.
The companion Section 30C residential clean energy credit for geothermal, solar, and other applications also ended its enhanced rate at the same time for most residential scenarios.
What Savings Are Still Available in 2026?
The federal credit ending does not mean all savings ended. Multiple programs continue to offer substantial rebates for energy-efficient water heater upgrades in 2026.
State Rebate Programs
Many states run their own energy efficiency rebate programs independent of federal incentives. These are funded through state utility commissions, energy offices, and ratepayer funds — not federal appropriations — so they continue regardless of what happens in Washington.
California statewide programs offer rebates up to $1,500 for qualifying heat pump water heaters. Massachusetts, New York, and Colorado all maintain active 2026 rebate programs for residential water heater upgrades. Some states tie rebates directly to Energy Star certification rather than CEE tiers, which expands the pool of qualifying equipment.
For a full breakdown by state, see our state water heater rebates and tax credits guide for 2026.
Utility Company Rebates ($500 to $3,000)
Utility rebates are often the most accessible and fastest-paying incentive. Your electric or gas utility may offer direct rebates for switching to a heat pump water heater, often paid as a bill credit or check within 60 to 90 days of installation. These programs are funded separately from federal energy policy and remain fully active in 2026.
Here is a snapshot of current 2026 utility rebate ranges:
| Utility / Region | Rebate Amount | Requirements |
|---|---|---|
| National Grid (NY/MA) | Up to $1,200 | Heat pump water heater, licensed install |
| PG&E (California) | Up to $1,500 | CEE Tier 3+, contractor enrolled |
| Xcel Energy (CO/MN) | Up to $1,000 | Energy Star certified |
| ComEd (Illinois) | $600 to $1,000 | Energy Star, replace existing electric |
| Puget Sound Energy (WA) | Up to $800 | Heat pump upgrade, licensed install |
| Georgia Power | Up to $750 | Heat pump water heater, residential |
Amounts vary by program year and may be subject to funding caps. For a full list of active 2026 utility programs, see our water heater utility rebates guide.
Income-Qualified Programs
If your household income falls below 80% of the area median income (AMI), you may qualify for deeper assistance programs that cover far more than a standard rebate.
- LIHEAP (Low Income Home Energy Assistance Program): Federal funding distributed through state agencies. Covers water heating costs and equipment upgrades for income-qualified households. Still funded in 2026.
- Utility Low-Income Programs: Most major utilities have separate income-qualified tiers offering free or heavily subsidized equipment. Some cover 100% of a heat pump water heater installation.
- Weatherization Assistance Program (WAP): Federal program providing home energy efficiency upgrades to qualifying households, including water heater replacement.
- State LIHEAP Supplements: States like New York (NYSERDA), California (CAA agencies), and Massachusetts (HEARTWAP) layer additional funding on top of federal LIHEAP.
Manufacturer Rebates and Promotions
Rheem, A.O. Smith, Bradford White, and other major manufacturers run seasonal rebate promotions directly. These typically range from $50 to $300 and stack on top of utility and state rebates. Check the manufacturer website directly or ask your installer — contractors who are factory-authorized dealers often have access to rebate programs not listed publicly.
How to Stack Incentives for Maximum Savings in 2026
The absence of the federal credit does not mean you cannot achieve significant savings — it means you need to stack what remains. Here is how a California homeowner might approach a heat pump water heater purchase in 2026:
| Incentive Source | Potential Value | Status |
|---|---|---|
| Federal Section 25C Credit | Up to $2,000 | EXPIRED (Dec 31, 2025) |
| California State Rebate | Up to $1,500 | Active 2026 |
| PG&E Utility Rebate | Up to $1,500 | Active 2026 |
| Manufacturer Rebate | $100 to $300 | Active (seasonal) |
| Total Available (CA example) | Up to $3,300 | Active 2026 |
The federal $2,000 loss is real, but combined state and utility incentives in high-incentive states can offset a substantial portion of the total cost. In some markets, the combined value of remaining programs exceeds what the federal credit alone would have provided.
- Check your state program first — use our state rebates guide to confirm your state 2026 availability and amounts.
- Call your utility — ask specifically about heat pump water heater rebates for 2026. Many utilities also have an online rebate lookup tool.
- Get an enrolled contractor — many utility rebates require the installer to be enrolled in the rebate program. Ask contractors upfront if they participate.
- Stack manufacturer promotions — ask your installer about current manufacturer promotions before ordering equipment.
Will the Federal Water Heater Tax Credit Come Back?
Possibly, but not soon. As of May 2026, there is no active legislation to restore Section 25C residential water heater credits. Current congressional budget priorities focus on spending reduction rather than energy incentive expansion.
Historically, energy efficiency credits have been extended multiple times — the 25C credit itself was renewed and expanded several times between 2005 and 2022. A future administration or congressional session could revive it. But counting on a potential future credit is not a sound financial strategy for a purchase you need to make now.
Any budget reconciliation bill or energy omnibus package in 2026 or 2027 could include a credit restoration. If you are weighing a heat pump water heater upgrade, state and utility rebates available now are a more reliable incentive than speculative federal credits.

Frequently Asked Questions
Can I still claim the federal water heater tax credit on my 2025 tax return?
Yes — if you installed a qualifying heat pump water heater before December 31, 2025, you can claim the Section 25C credit on your 2025 federal tax return. The credit applies to the year the installation was completed. File IRS Form 5695 with your 2025 return.
Does the credit apply to equipment purchased in 2025 but installed in 2026?
No. The credit is based on when the installation is placed in service, not when the equipment was purchased. If you bought a heat pump water heater in December 2025 but it was not installed and operational until January 2026, it does not qualify for the federal credit.
Are there any federal water heater incentives left in 2026?
Not for standard residential installations. The Section 25C credit covered the most common residential scenario. LIHEAP and WAP are federally funded but are income-restricted assistance programs, not tax credits. There is no broad-based federal tax credit for water heaters purchased or installed in 2026.
Does a standard electric water heater qualify for rebates in 2026?
Standard resistance electric water heaters rarely qualify. Rebate programs are specifically designed to incentivize switching to more efficient technology. Heat pump water heaters are the primary qualifying technology. If you replace a gas heater with an electric heat pump model, you may qualify for additional fuel-switching incentives from your utility.
How do I find my utility water heater rebate program?
The ENERGY STAR rebate finder at energystar.gov/rebate-finder allows you to search by zip code and product type. You can also call the customer service number on your utility bill and ask specifically for the energy efficiency or demand-side management department. Our utility rebates guide covers the largest programs by region.
What heat pump water heater brands qualify for state and utility rebates?
Most major brands qualify as long as the specific model meets the Energy Star or CEE tier requirement specified by the program. Rheem ProTerra, A.O. Smith Voltex, Bradford White Aerotherm, and GE GeoSpring models are among the most widely certified. Always verify the specific model number against the program qualifying equipment list before purchasing.
Can I combine a state rebate with a utility rebate?
Yes, in most cases. State and utility rebates are funded and administered separately, and most programs explicitly allow stacking. Some programs require the combined rebate to not exceed the total cost of equipment and installation — which in practice rarely becomes a binding constraint for heat pump water heaters.
What is the best water heater to buy in 2026 for maximum rebates?
A heat pump water heater with a UEF of 3.0 or higher qualifies for the most rebate programs. Models like the Rheem ProTerra 50-gallon (UEF 3.75) and A.O. Smith Voltex 50-gallon (UEF 3.45) are consistently on state and utility approved lists. See our full breakdown in the best water heater guide.
