Water Heater Tax Credits & Rebates (2025)
Updated February 25, 2026
The Inflation Reduction Act extended and expanded energy efficiency tax credits through 2032. Heat pump water heaters qualify for a 30% federal tax credit up to $2,000 per year. Solar water heaters get 30% with no cap. Even some high-efficiency gas models qualify for $150. These credits reduce the effective cost of an efficient water heater to the same level as -- or less than -- a standard model. Here is what qualifies, how much you save, and how to claim it.

Cost Breakdown
Heat Pump Water Heaters: 30% Credit, Up to $2,000
- The biggest incentive.
- Under Section 25C of the tax code, heat pump water heaters that meet Energy Star requirements qualify for a 30% tax credit on the total cost (unit + installation), up to $2,000 per year.
- A $2,500 installed heat pump qualifies for a $750 credit.
- A $3,500 installed heat pump qualifies for a $1,050 credit.
- The $2,000 cap is per year -- if you install a heat pump water heater and a heat pump HVAC system in the same year, each qualifies separately up to the $2,000 annual cap for water heaters.
- This is a tax credit, not a deduction -- it reduces your tax bill dollar for dollar.
Solar Water Heaters: 30% Credit, No Cap
- Solar water heaters qualify under Section 25D (Residential Clean Energy Credit) for 30% of the total installed cost with no dollar cap.
- A $5,000 solar system gets a $1,500 credit.
- A $7,000 system gets a $2,100 credit.
- The system must provide at least half of the home's hot water to qualify.
- The solar collectors must be certified by the Solar Rating and Certification Corporation (SRCC).
- This credit applies through 2032, then drops to 26% in 2033 and 22% in 2034.
Gas Water Heaters: $150 Credit (Limited)
- Natural gas and propane water heaters that meet the highest efficiency tier qualify for a $150 tax credit under Section 25C.
- The unit must have a Uniform Energy Factor (UEF) of 0.95 or higher for gas storage tanks.
- Gas tankless units with UEF of 0.95+ also qualify.
- Most condensing tankless models (Navien, Rinnai RU series, Noritz EZ series) meet this threshold.
- Standard non-condensing gas tanks and tankless units typically do not qualify.
- The $150 credit is modest but covers the cost difference between a standard and high-efficiency gas unit.
State and Utility Rebates (Stack on Top)
Many states and utilities offer additional rebates that stack on top of the federal credit. Examples: California TECH Clean program offers up to $3,600 for heat pump water heaters for low-income households. Massachusetts offers $750 for heat pump water heaters through Mass Save. Oregon offers $300-$500 through Energy Trust of Oregon. Many water utilities offer $50-$200 for WaterSense-certified models. Check dsireusa.org (Database of State Incentives for Renewables and Efficiency) for your specific state and utility rebates. These change annually.
How to Claim the Federal Credit
- File IRS Form 5695 (Residential Energy Credits) with your annual tax return.
- You need: the manufacturer's certification statement (available on the manufacturer's website), the receipt showing the total cost (unit + installation), and the model number to verify Energy Star qualification.
- The credit applies to the year the installation was completed.
- If you do not owe enough taxes to use the full credit in one year, the remaining amount can be carried forward to the next year for the Section 25D (solar) credit.
- The Section 25C (heat pump, gas) credit cannot be carried forward -- use it or lose it in the installation year.
Safety Warnings
- Assuming all heat pump or tankless water heaters automatically qualify. Only models that meet the specific Energy Star or UEF threshold qualify. Check the Energy Star product list before buying.
Pro Tips
- The heat pump credit alone can reduce a $2,500 installed cost to $1,750 -- making it cheaper than a standard electric tank over a 5-year period when you include operating cost savings.
- Stack federal + state + utility rebates. In some states, the combined incentives cover 50-70% of the heat pump water heater cost.
- Keep all receipts and the manufacturer's certification statement. The IRS requires documentation to support the credit on Form 5695.
- Time your purchase strategically. If you are replacing a water heater late in the year and do not have enough tax liability to use the credit, consider waiting until January to install in a year with higher expected taxes.
Mistakes to Avoid
- Assuming all heat pump or tankless water heaters automatically qualify. Only models that meet the specific Energy Star or UEF threshold qualify. Check the Energy Star product list before buying.
- Confusing tax credits with tax deductions. A $1,000 credit reduces your tax bill by $1,000. A $1,000 deduction reduces your taxable income by $1,000 (saving you $220-$370 depending on bracket). Credits are much more valuable.
- Not checking state and utility rebates in addition to the federal credit. Many people leave $200-$1,000 in additional savings on the table.
- Installing a qualifying unit in December but not filing Form 5695 with that year's tax return. The credit must be claimed for the year of installation.
Bottom Line
Heat pump water heaters qualify for a 30% federal tax credit up to $2,000. Solar gets 30% with no cap. High-efficiency gas gets $150. State and utility rebates stack on top. A $2,500 heat pump installation may net out to $1,200-$1,750 after all incentives. These credits make high-efficiency water heaters cost-competitive with standard models on day one -- and then save $200-$400/year in operating costs for the next 15+ years.
