The Federal Window Tax Credit Ended December 31, 2025
If a window company tells you your 2026 project qualifies for the $600 federal tax credit, they are reading last year’s brochure. The IRS states it plainly: the Energy Efficient Home Improvement Credit — the program that returned 30% of qualifying window costs up to $600 per year — can be claimed only for improvements made through December 31, 2025. Windows installed in 2026 do not qualify. The credit’s early sunset was enacted in 2025 federal tax legislation, years ahead of its original 2032 schedule.
What This Means for Your 2026 Project
- Budget on the real number. No federal rebate arrives at tax time to soften the invoice. The good news: in a cooling climate, efficient glass pays through the electric bill whether or not a credit exists — the case for solar-control Low-E in Wichita Falls never rested on the credit.
- Treat the credit as a freshness test. A bid or website still advertising the $600 credit for new 2026 installs tells you how current the rest of its claims are.
- 2025 installs still count at filing time. If your windows were placed in service on or before December 31, 2025, you claim the credit on the tax return for 2025 using IRS Form 5695 — keep manufacturer certification statements and your invoice.
What Savings Remain in 2026
The electric bill is the standing rebate. Replacing single-pane aluminum with solar-control Low-E double-pane units attacks the biggest window-driven cost in a Texas home — summer cooling. That saving arrives monthly, forever, and never required a form.
Utility programs come and go. Texas electric utilities periodically run residential efficiency programs. Offerings change year to year and by provider, so check your own electric provider’s current programs directly rather than trusting a contractor’s blanket promise — and remember Texas has no state income tax, so there is no state-level tax credit to replace the federal one.
Insurance-funded replacement is its own lane. When spring hail takes your windows, the claim — not a tax credit — funds the replacement, and the upgrade conversation happens inside it. See storm and hail damage windows.
Off-season scheduling is negotiable money. Fall and winter calendars leave local installers room to sharpen elective-work pricing. It is not a government program, but it is real and it is available every year.
