The federal tax credit for energy-efficient windows and doors has ended. The credit, the Energy Efficient Home Improvement Credit (Section 25C of the tax code), is not allowed for any property placed in service after December 31, 2025. Windows and doors installed in 2026 or later get no federal credit.
What changed
Public Law 119-21, signed July 4, 2025, ended the credit. The IRS confirms the end date.
What if my windows were installed in 2025?
The IRS says you can claim the credit for improvements made through December 31, 2025. Ask your tax professional how that applies to your return.
Are there other incentives?
Your local utility may offer its own rebates. Check with them, because programs change. Energy Shield does not set or administer tax credits or rebates.
New windows can still cut the heat coming into your home. See how much solar heat our windows block and what they cost.
