If you are searching for a window tax credit in 2026, you probably heard about the 30% federal credit and want to know if you still qualify. Straight answer: the credit ended December 31, 2025. There is also no PECO or PPL rebate for replacement windows. What does exist for Pennsylvania homeowners is low-rate financing, and this page shows exactly what is on the table.
What Was Available: The Federal 25C Tax Credit
The 25C Energy Efficient Home Improvement Credit was terminated by the One Big Beautiful Bill Act (Public Law 119-21), signed July 4, 2025. Here is what it covered:
- Amount: 30% of qualifying window costs, materials only
- Cap: $600 per year for windows and skylights combined
- Ended: December 31, 2025, for property placed in service after that date
Installed windows in 2025? If you installed qualifying ENERGY STAR windows in 2025, you may be able to claim the 25C credit on your 2025 tax return using IRS Form 5695. Consult your tax advisor. YBR can provide ENERGY STAR certification documentation for qualifying products we installed.
PECO and PPL Rebates Do Not Cover Windows
PECO and PPL run Act 129 energy efficiency programs, but replacement windows have never been part of them. PECO rebated items like insulation, air sealing, and heat pump equipment. PPL’s program covered the same kinds of measures. Act 129 Phase IV ended May 31, 2026, and Phase V began June 1, 2026. The utilities have not yet published their Phase V amounts or eligible measure lists, so check peco.com and pplelectricsavings.com for current details.
What Pennsylvania Homeowners Can Use in 2026
1. PHFA HEELP Loan
The Pennsylvania Housing Finance Agency Homeowners Energy Efficiency Loan Program (HEELP) is the main tool for income-qualified homeowners replacing windows this year.
- Loan amount: $1,000 to $10,000
- Rate: 1% APR, fixed, 10-year term, no prepayment penalty
- Income limit: about 80% of Area Median Income, roughly $81,600 for a 4-person household in Bucks County (confirm current limits at phfa.org)
- Contractor: HEELP requires a PHFA-approved contractor, so confirm before you start
2. PA KEEP Loan
The Keystone Energy Efficiency Plus Home Energy Loan (KEEP) has no income restriction. It covers $2,500 to $25,000 over 36 to 120 months at a below-market rate you confirm at application. It suits larger window projects or households above the HEELP income limit.

Will Congress Bring Back the 25C Credit?
As of this update there is no signed legislation restoring the 25C window credit. If that changes, YBR will update this page.
ENERGY STAR Specs That Still Matter
Even without a credit, ENERGY STAR specifications matter because HEELP sets minimum efficiency standards. Bucks County sits in the Northern climate zone (IECC Climate Zone 4A). Under ENERGY STAR V7.0:
| Specification | ENERGY STAR V7.0 Value | What It Means |
|---|---|---|
| U-factor | 0.22 or lower | Heat loss through the window; lower is better |
| SHGC | 0.17 or higher | Solar heat gain; higher captures winter sun |
