Replacement Windows in New Jersey

Rebates & incentives

The federal window tax credit (25C) ended for projects placed in service after December 31, 2025. If your windows were installed in 2025, you can still claim it on your 2025 return — but for new projects there is no federal window credit. State and utility programs are now the main source of window incentives.

New Jersey's IRA Home Energy Rebate programs are administered by the Board of Public Utilities (BPU) under New Jersey's Clean Energy Program framework. As of mid-2026 the state was preparing to launch federally funded HOMES (whole-home efficiency) and HEAR pathways — windows would generally qualify only inside a modeled whole-home savings project, not as a simple per-window check. Confirm current launch status and eligibility on njcleanenergy.com and nj.gov/bpu before counting on rebate dollars.

• New Jersey's Clean Energy Program (NJCEP). The statewide Clean Energy Program (BPU) and participating utilities fund residential efficiency through home energy assessments, weatherization, and equipment measures. Standalone replacement-window rebates are not a reliable headline offer — envelope work that includes windows is more often pursued through whole-home or income-qualified pathways. Confirm current residential offerings on njcleanenergy.com. (New Jersey Clean Energy Program (njcleanenergy.com); NJ BPU)
• Comfort Partners (income-eligible weatherization). Comfort Partners is New Jersey's income-eligible utility weatherization program, delivered through participating electric and gas utilities. It can include envelope measures for qualifying households, but eligibility and scope are income- and audit-driven rather than a retail per-window rebate. Confirm with your utility or NJCEP.

Energy code

New Jersey enforces the Uniform Construction Code (N.J.A.C. 5:23), IECC-based, through local construction code officials. Most of the state is IECC climate zone 4A (mixed-humid); ENERGY STAR North-Central targets for replacement windows are a U-factor of 0.25 or lower and an SHGC of 0.40 or lower under Version 7.0.
