The federal 25C credit is gone. Here's an honest look at what incentives remain for window and door replacements in 2026 — and where homeowners can still find meaningful savings.

Let's be direct: windows and doors are the hardest category to find significant financial incentives for in 2026. The 25C federal credit was the primary incentive driver, and it expired. The remaining programs are modest — utility rebates of $2–$10 per window don't move the needle on a $15,000 window replacement project.
That doesn't mean windows aren't worth doing — the energy savings and comfort improvements are real, and new windows add home value. But homeowners should go in with accurate expectations about available incentives and focus on the financial benefits that don't require a program: lower energy bills, reduced HVAC load, and increased home resale value.
1. Utility Rebates
Many electric and gas utilities still offer ENERGY STAR window rebates. They're small ($2–$10 per window) but legitimate and stackable with manufacturer rebates. Use the ENERGY STAR rebate finder at energystar.gov to see your utility's current program.
2. Manufacturer Seasonal Promotions
Andersen, Pella, Marvin, and Milgard run real seasonal rebate promotions — typically $50–$300 per window during spring and fall. Ask your contractor what's currently active. These aren't permanent programs, so timing matters.
3. Income-Qualifying Weatherization Programs
The DOE Weatherization Assistance Program provides free or subsidized window replacement for income-qualifying households. If you're at or below 200–250% of the federal poverty level, this can cover your entire project cost.
4. Mass Save (Massachusetts Only)
Massachusetts utilities continue to offer weatherization incentives that can apply to air sealing and insulation work alongside window replacement. Get a free Mass Save assessment first to understand what's covered.
Without a compelling incentive, the financial case for window replacement rests on:
No. The federal 25C Energy Efficient Home Improvement Credit expired December 31, 2025. It previously offered up to $600 per window/door category for ENERGY STAR certified products. Homeowners who installed qualifying windows and doors in 2025 can still claim the credit on their 2025 tax returns. No federal credit is available for 2026 window or door installations.
The primary remaining incentives are: utility rebates (typically $2–$10 per window from many electric and gas utilities), state weatherization programs for income-qualifying households, Mass Save rebates in Massachusetts, and seasonal manufacturer promotions from brands like Andersen, Pella, Marvin, and Milgard. Enter your ZIP to see what your specific utility offers.
Massachusetts utilities continue to offer weatherization incentives that can include air sealing and insulation work that pairs with window replacement projects. The rebates aren't specifically for windows, but the combination of air sealing and insulation upgrades that contractors typically do alongside window replacements often qualifies for Mass Save incentives.

Yes — major manufacturers like Andersen, Pella, Marvin, and Milgard regularly run seasonal promotional rebates, typically $50–$300 per window during spring and fall install seasons. These are real cash rebates sent directly from the manufacturer or processed through your contractor. Ask your window contractor what manufacturer programs are currently active — they change seasonally and aren't permanently available.
Income-qualifying homeowners may access free or heavily subsidized window replacement through the DOE Weatherization Assistance Program (WAP) and state equivalents. Eligibility is typically based on income being at or below 200–250% of the federal poverty level. Contact your state energy office or local community action agency to apply. Processing times vary by state but the program is nationwide.
