Every NJ homeowner planning a window replacement project searches for the window replacement tax credit – and in 2026, most of what they find online is wrong. Dozens of contractor websites and national home improvement guides are still advertising a 30 percent federal tax credit that expired on December 31, 2025. Budgeting for a credit that no longer exists can add thousands of dollars of unexpected cost to your project.
This guide gives NJ homeowners the accurate, sourced 2026 picture. The federal program is gone. But NJ state programs, utility rebates, and income-qualified assistance remain active and can still meaningfully reduce your project cost – if you know how to access them.
| ⚠️ Important 2026 Update: The federal Section 25C window replacement tax credit expired on December 31, 2025. It cannot be claimed on windows installed in 2026. NJ state and utility programs remain active. The facts, the details, and the bottom line-all in one guide. |

The Federal Section 25C Credit: What It Was and Why It Is Gone
The Energy Efficient Home Improvement Credit (Section 25C) was the primary federal incentive for window replacement. It allowed homeowners to claim 30 percent of qualifying window product costs – not including labor – up to $600 per year for windows and skylights combined. Under the Inflation Reduction Act of 2022, it had been extended through December 31, 2032.
The One Big Beautiful Bill Act (P.L. 119-21), signed into law on July 4, 2025, repealed Section 25C early. The credit terminated for any property placed in service after December 31, 2025. The IRS confirmed the cutoff: the credit will not be allowed for any property placed in service after that date.
| ⚠️ Critical Distinction: “Placed in service” means the installation is complete and the windows are fully operational – not the date you signed a contract, paid a deposit, or placed an order. Windows ordered in December 2025 but installed in January 2026 do not qualify for the credit. |
What If My Windows Were Installed in 2025?
If your windows were fully installed and operational by December 31, 2025, you can still claim the Section 25C credit on your 2025 federal tax return filed in 2026. You will need IRS Form 5695, your contractor’s invoice, and a Qualified Manufacturer Identification Number (QMID) from the window manufacturer. Consult a tax professional to ensure accurate filing.
What Is Still Available: Active NJ Programs in 2026
1. NJ Whole Home Energy Efficiency Program (NJCEP)
Active in 2026 Available to all NJ residents in PSE&G, JCP&L, Atlantic City Electric, or Orange & Rockland service areas.
This is the most significant savings opportunity remaining for most NJ homeowners. The program provides tiered cash-back incentives based on total projected energy savings achieved across the home, plus zero-interest financing of up to $25,000 for qualifying projects.
The incentive structure is: $2,000 for achieving 5 percent whole-home energy savings, plus $200 for each additional percentage point, up to a maximum of $7,500.
Critical detail: Windows alone are unlikely to hit the 5 percent savings threshold required to trigger the rebate. The program is designed for comprehensive home upgrades. Windows bundled with insulation, air sealing, or HVAC improvements regularly reach the minimum threshold. A window-only project should be evaluated as a starting point for a broader energy plan, not as a standalone rebate-qualifying project.
| How to Start: Visit NJCleanEnergy.com and request a Home Performance with Energy Star assessment. The certified auditor identifies which improvements qualify and calculates your projected savings percentage before any work begins. |
To qualify for any NJ rebate program, windows must meet Energy Star Northern Zone specifications. In NJ, that means a U-factor of 0.22 or lower and an SHGC of 0.17 or higher. For a full breakdown of which glass packages and frame materials meet these specs, see our guide on energy-efficient windows in New Jersey.
2. PSE&G Energy Efficiency Rebate Program
Active – PSE&G customers only. Available to PSE&G electric or gas customers in NJ. Requires a home energy assessment through a PSE&G-approved auditor first.
PSE&G offers per-window rebates for Energy Star Most Efficient rated windows with a U-factor of 0.22 or lower and SHGC of 0.17 or higher for the Northern Zone. The rebate is capped at a fixed number of windows per household per year.
Rebate amounts and availability change as program funding is allocated throughout the year. Confirm the current per-window amount directly on the PSE&G Marketplace before signing any installation contract, as these numbers shift periodically.
3. JCP&L Energy Efficiency Rebate Program
Active – JCP&L customers only. Available to JCP&L (FirstEnergy) customers in western and central NJ. Rebates available up to $1,000 for qualifying whole-home projects.
JCP&L offers rebates for qualifying energy improvements, including windows as part of a comprehensive home energy project. The structure mirrors NJCEP – a home energy assessment is required before installation, and the rebate is based on total projected energy savings rather than windows alone. Check JCP&L’s energy efficiency portal for current rates.
4. NJCEP Comfort Partners Program – Expanded Eligibility in 2026
Active – Income-qualified households. Income limit expanded to 400% of the federal poverty level in 2026. For a family of four in NJ, that is roughly $124,800 in annual household income.
The Comfort Partners program provides qualifying households with free home energy audits, free direct-install measures including LEDs and smart thermostats, and substantially higher rebates on Energy Star windows and insulation. The 2026 expansion of the income threshold from 200 percent to 400 percent of the federal poverty level makes this program accessible to a much larger segment of NJ homeowners than most guides describe.
5. Weatherization Assistance Program (WAP)
Active – Lowest-income households. Covers window replacement at no cost for households below 200% FPL, veterans with 100% disability benefits, and SNAP or TANF recipients.
The Weatherization Assistance Program is administered locally through community action agencies across NJ. It provides free window replacement as part of a comprehensive home weatherization package for qualifying households. Contact NJ Clean Energy at 1-866-NJSMART to be connected with your local administering agency.
6. NJ Historic Property Reinvestment Act Tax Credit
Active – Historic properties only: 25% state income tax credit on qualifying rehabilitation costs, capped at $25,000 per property. Applies to NJ Register of Historic Places owner-occupied primary residences.
For NJ homeowners in registered historic districts, this state tax credit applies to window replacement when it is part of a board-approved rehabilitation plan. Properties in towns like Princeton, Red Bank, and Rumson with significant historic stock may qualify. Contact the NJ Historic Preservation Office to confirm your property’s eligibility before planning the project.
How to Maximize NJ Window Rebates in 2026
The single most important strategy for maximizing NJ window savings in 2026 is bundling. No current NJ program pays meaningful rebates for window replacement alone. Every active program is designed for comprehensive home energy improvement. Here is how to approach it.
- Start with a home energy assessment through NJCleanEnergy.com before signing any window contract. The assessment is free and identifies which improvements qualify for rebates and at what savings percentage.
- Bundle windows with insulation and air sealing. This combination is the most reliable way to reach the 5 percent energy savings threshold that triggers NJCEP Whole Home rebates.
- Confirm your utility. The rebate programs available to you depend on whether you are a PSE&G, JCP&L, ACE, or RECO customer. Each utility has its own rebate structure and current funding availability.
- Specify correctly: Specify Energy Star Northern Zone-certified windows. U-factor of 0.22 or lower is the standard requirement across all active NJ programs. Confirm this before ordering.
- Never budget federal credits for a 2026 installation. The Section 25C credit is gone. Treat any NJ rebates as a bonus after confirming current program funding, not as guaranteed project income.

Frequently Asked Questions
How do I know if windows qualify for a tax credit?
For windows installed in 2025 and claimed on your 2025 tax return, they must have been Energy Star Most Efficient certified for the Northern Climate Zone (U-factor 0.22 or lower, SHGC 0.17 or higher) and fully installed and operational by December 31, 2025. You also need a Qualified Manufacturer ID Number (QMID) from the manufacturer and must file IRS Form 5695. For windows installed in 2026, there is no federal tax credit to qualify for. NJ state programs require Energy Star Northern Zone certification regardless of what federal credits may or may not exist.
Can you claim a tax credit for new windows in 2026?
No federal tax credit is available for windows installed in 2026. The Section 25C Energy Efficient Home Improvement Credit was repealed by the One Big Beautiful Bill Act (P.L. 119-21), signed July 4, 2025, and terminated for any property placed in service after December 31, 2025. The IRS confirmed this deadline. If you installed qualifying windows in 2025, you can still claim the credit on your 2025 tax return filed in 2026. For new 2026 installations, NJ state and utility rebate programs are the only available financial incentives.
Do you get a tax credit for installing new windows?
Not for windows purchased and installed in 2026. The federal Section 25C credit that previously covered 30 percent of qualifying window product costs up to $600 per year expired December 31, 2025. Note that the credit never covered labor, delivery, or installation – only the cost of the windows themselves. For 2026 purchases, NJ Clean Energy program rebates and utility rebates from PSE&G and JCP&L are the available savings options, though these require a home energy assessment and Energy Star Northern Zone certified windows to qualify.
What is the 30% federal tax credit, and how does it work?
The 30 percent federal tax credit under Section 25C applied to qualifying window product costs only – not labor or installation – up to an annual cap of $600 for windows and skylights combined. It was a dollar-for-dollar reduction on your federal tax bill, not a rebate or refund. This credit applied to windows installed between January 1, 2023, and December 31, 2025. The One Big Beautiful Bill Act, signed July 4, 2025, repealed it, and it cannot be claimed for any windows installed after December 31, 2025.
