Federal Home Energy Tax Credits in 2026: What Expired and What Still Helps
Federal home energy tax credits like the Energy Efficient Home Improvement Credit (25C) and Residential Clean Energy Credit (25D) expired on December 31, 2025, due to the One Big Beautiful Bill Act. Homeowners planning energy-efficient upgrades in 2026 should instead focus on state programs, local utility rebates, and manufacturer incentives.
The End of Federal Home Energy Tax Credits: What Changed for 2026
For homeowners planning energy-efficient upgrades in 2026, it's crucial to understand a significant shift in federal incentives. The landscape of federal home energy tax credits has changed dramatically, with the two major programs terminating at the end of 2025. This means that for property placed in service on or after January 1, 2026, the federal tax credits you might have heard about are no longer available.
Specifically, the One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025, effectively ended both the Section 25C (Energy Efficient Home Improvement Credit) and Section 25D (Residential Clean Energy Credit) programs. These credits, which previously offered substantial savings for improvements like heat pumps, solar panels, and insulation, ceased for any equipment or systems installed and operational after December 31, 2025. The key date here is the “placed in service” date—when the equipment is fully installed and working—not when you purchased it or signed a contract.
This change means that while federal incentives were a powerful motivator for energy-efficient upgrades in previous years, homeowners must now look to other avenues for financial assistance in 2026 and beyond. Understanding this transition is the first step in planning your next home improvement project intelligently.
What Federal Credits Are No Longer Available for 2026?
To be clear, if you are undertaking an energy-efficient home improvement project in 2026, you will generally not be able to claim the following federal tax credits:
Section 25C: The Energy Efficient Home Improvement Credit
This credit previously covered a broad range of home energy improvements. In its final form, it offered a credit for 30% of the cost of eligible improvements, up to a maximum of $1,200 annually. There were also specific caps for certain types of equipment:
- Heat Pumps and Heat Pump Water Heaters: A separate annual credit of up to $2,000 was available for these high-efficiency systems. This significantly helped offset heat pump installation costs and heat pump water heater costs.
- Insulation and Air Sealing: Improvements like attic insulation costs, wall insulation, and air sealing materials were eligible.
- Energy-Efficient Windows and Doors: Certain qualified exterior windows, skylights, and exterior doors also fell under this credit, helping with window replacement costs.
- Energy Audits: The cost of a home energy audit was also eligible for a credit.
- Furnaces and Boilers: High-efficiency natural gas, propane, or oil furnaces and boilers could qualify.
Status for 2026: TERMINATED. If your qualifying property was placed in service on or after January 1, 2026, it does not qualify for this credit.
Section 25D: The Residential Clean Energy Credit
This was another popular credit, particularly for homeowners looking to generate their own renewable energy. It offered a credit for 30% of the cost of eligible renewable energy systems, with no annual or lifetime cap. Covered items included:
- Solar Electric Property: Photovoltaic (PV) panels that generate electricity for your home.
- Solar Water Heating Property: Systems that heat water for your home using solar energy.
- Wind Energy Property: Small wind turbines that generate electricity.
- Geothermal Heat Pump Property: Geothermal systems that use the earth's stable temperature to heat and cool your home.
- Battery Storage Technology: Battery storage systems with a capacity of at least 3 kilowatt hours (kWh).
Status for 2026: TERMINATED. Similar to 25C, if your qualifying property was placed in service on or after January 1, 2026, it does not qualify for this credit.
Why Did These Federal Credits End Early?
The early termination of these federal energy tax credits stems from the passage of the One Big Beautiful Bill Act (OBBBA), Public Law 119-21, which was signed into law on July 4, 2025. This legislation included provisions that specifically set the expiration date for both Section 25C and Section 25D as December 31, 2025. While these credits had varying planned lifespans under previous legislation, the OBBBA superseded those timelines, bringing an earlier end to these federal incentives for energy-efficient home improvements.
For homeowners, this underscores the importance of staying informed about legislative changes, as they can directly impact the financial viability of home improvement projects. The unexpected nature of such legislative shifts means that relying solely on federal incentives for long-term planning can be risky.
What Still Helps Homeowners in 2026?
While the federal tax credit landscape has shifted, there are still significant opportunities for homeowners to save money on energy-efficient upgrades. You'll need to pivot your focus from federal tax forms to state programs, local utilities, and manufacturer offers.
State Energy-Efficiency Programs
Many states across the U.S. have robust programs designed to encourage energy efficiency and renewable energy adoption. These programs vary widely by state but can include:
- Grants: Direct financial assistance that does not need to be repaid.
- Rebates: Money back on the purchase and installation of qualifying energy-efficient equipment.
- Low-Interest Loans: Financing options specifically for energy upgrades, often with favorable terms.
- Property Tax Incentives: Reductions or exemptions on property taxes for homes with certain energy-efficient features.
To find out what's available in your area, you should consult your state's energy office or visit the DSIRE (Database of State Incentives for Renewables & Efficiency) website. DSIRE is an excellent resource for a comprehensive, up-to-date list of state-specific programs.
Local Utility Rebates
Your local electric and gas utility companies are often a prime source of incentives for energy-efficient upgrades. Utilities frequently offer rebates for equipment that reduces energy consumption, as it helps them manage demand and comply with energy conservation mandates. Common utility rebates include:
- Heat Pump Rebates: Incentives for installing high-efficiency heat pumps for heating and cooling.
- Insulation Rebates: Financial assistance for improving your home's insulation, such as attic or wall insulation.
- Smart Thermostat Rebates: Discounts or rebates for installing programmable or smart thermostats.
- Water Heater Rebates: Incentives for upgrading to more efficient water heaters, particularly heat pump water heaters.
It's crucial to check with your specific utility provider, as programs can differ even within the same state. Many utility websites have dedicated sections for energy-saving programs and rebates, or you can call their customer service line for details.
ENERGY STAR Certified Equipment
While not a direct financial incentive in the form of a tax credit, choosing ENERGY STAR certified products is a smart financial move for long-term savings. ENERGY STAR is a U.S. Environmental Protection Agency (EPA) program that helps consumers identify products with superior energy efficiency. Equipment with the ENERGY STAR label:
- Uses Less Energy: Leading to lower utility bills over the lifetime of the product.
- Reduces Carbon Footprint: Contributing to environmental sustainability.
- Often Qualifies for Other Incentives: Many state and utility programs specifically require ENERGY STAR certification for rebate eligibility.
When shopping for appliances, HVAC systems, windows, or other home products, always look for the ENERGY STAR label to ensure you're investing in energy efficiency.
Manufacturer and Seasonal Promotions
Don't overlook direct promotions from manufacturers or seasonal sales from retailers and contractors. These can include:
- Cash Back Offers: Direct rebates from the manufacturer after purchasing certain models.
- Instant Discounts: Price reductions offered at the point of sale.
- Special Financing: Low or no-interest financing options for a limited time.
It's always worth asking your contractor or retailer about any current promotions that might apply to your planned upgrades.
Property Assessed Clean Energy (PACE) Financing
In some states and local jurisdictions, PACE financing is available. PACE programs allow property owners to finance energy efficiency, renewable energy, and water conservation improvements through a voluntary assessment on their property tax bill. Key features of PACE include:
- No Upfront Costs: Projects can be financed with no money down.
- Long Repayment Terms: Repayment periods can extend up to 20 or 30 years, aligning with the useful life of the improvements.
- Secured by Property: The assessment is tied to the property, not the individual, and transfers with ownership if the property is sold.
PACE availability varies significantly by location, so check if it's an option in your community. It's important to understand the terms and implications of PACE financing thoroughly, as it places a lien on your property.

Navigating Your Energy-Efficient Project in 2026
Planning an energy-efficient home improvement project in 2026 requires a proactive approach to identifying available financial assistance. Here's a recommended strategy:
- Identify Your Project: Determine what energy-efficient upgrades you want to make (e.g., new heat pump, better insulation, efficient windows).
- Research State Programs: Visit your state's energy office website or the DSIRE database to find statewide grants, rebates, or loan programs.
- Contact Your Utility: Check your local electric and gas utility websites or call their customer service to inquire about current rebates for your planned improvements.
- Look for ENERGY STAR: Prioritize equipment and products that are ENERGY STAR certified to maximize long-term savings and often qualify for other incentives.
- Inquire with Contractors/Retailers: Ask about any manufacturer promotions, seasonal sales, or special financing options they might be offering.
- Consider PACE (if available): If you are in an eligible area, explore PACE financing as an option for larger projects with no upfront cost.
- Consult a Tax Professional: Even though federal credits are gone, it's always wise to confirm current tax laws and any potential state tax implications with a qualified tax advisor. Programs and rules can change, and a professional can provide the most accurate, personalized advice for your situation.
By taking these steps, you can still significantly reduce the cost of your energy-efficient home improvements and enjoy the long-term benefits of lower utility bills and a more comfortable home, even without the federal tax credits of years past.

Frequently asked questions
Can I still claim federal energy tax credits for a project completed in early 2026 if I signed the contract in 2025?
No. The IRS uses the "placed in service" date, meaning the date the equipment was fully installed and operational. If your project was completed and placed in service on or after January 1, 2026, it does not qualify for the federal 25C or 25D credits, regardless of when you signed the contract or purchased the equipment.
Where is the best place to start looking for energy efficiency incentives in 2026?
Begin by checking your state's energy office website or the DSIRE database for statewide programs. Simultaneously, contact your local electric and gas utility companies, as they often offer specific rebates for energy-efficient equipment like heat pumps and insulation in your service area.
Are there any federal programs at all that can help with home energy costs in 2026?
While the direct tax credits (25C and 25D) are gone, some broader federal programs, such as those that support low-income weatherization or specific rural development, might still exist through other agencies. However, these are not universal homeowner tax credits and typically have strict eligibility requirements. Your primary focus for general home improvements should be on state and local incentives.
