Energy Star Information for Window Tax Credits in 2026
Replacement Windows & New Construction Window Incentives Explained
If you’re planning to install replacement windows or new construction windows in 2026, it’s important to understand how federal energy tax credits apply — and where they no longer do.
At Vinyl Windows Co, we believe informed homeowners make better decisions. Below is a clear breakdown of what tax incentives are (and are not) available for windows installed in 2026.
Energy Star Information
Are There Federal Tax Credits for Replacement Windows in 2026?
❌ No Federal Window Tax Credit for 2026 Installations
As of 2026, there is no federal Energy Star or IRS tax credit available for replacement windows installed in 2026.
The Energy Efficient Home Improvement Credit (IRC Section 25C) — which previously allowed homeowners to claim 30% of the cost of qualifying windows (up to $600 annually) — expired on December 31, 2025.
Important Clarification
- Windows installed in 2026 do not qualify for the federal 25C tax credit
- Windows installed in 2025 may still be claimed on a 2025 tax return (filed in 2026)
- ENERGY STAR® certification alone does not create a tax credit in 2026
What About Tax Credits for New Construction Windows?
❌ No Direct Federal Tax Credit for Homeowners
There is no federal tax credit for homeowners installing windows in new construction homes in 2026.
Historically, window-related tax incentives applied only to existing homes, not new construction.
Why ENERGY STAR® Windows Still Matter in 2026
Even without a federal tax credit, ENERGY STAR®–certified windows remain a smart investment due to:
- Lower heating and cooling costs
- Improved indoor comfort year-round
- Reduced UV damage to flooring and furniture
- Better resale appeal for energy-conscious buyers
ENERGY-efficient windows continue to deliver long-term savings, even when tax incentives are unavailable.
Are State or Utility Rebates Available?
✅ Possibly — and They Vary by Location
While federal credits for windows ended after 2025, state, local, and utility rebate programs may still exist in 2026, depending on where you live.
These programs can include:
- Utility company rebates for energy-efficient upgrades
- State-level energy efficiency incentives
- Local sustainability or green-home programs
Availability, eligibility, and rebate amounts vary by region and program.

Builder & Developer Incentives (Not Homeowner Credits)
While homeowners cannot claim window tax credits in 2026, builders and developers may still benefit from separate federal programs, such as:
Energy-Efficient Home Builder Credits (IRC Section 45L)
Incentives tied to whole-home energy performance, not individual windows
These programs apply to builders — not retail homeowners — and are not claimed on a homeowner’s personal tax return.
