Rebates & incentives in Texas
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.
Texas accepted IRA rebate funding but program rollout has lagged; check the State Energy Conservation Office for current status before counting on it. See our Brownsville guide for the full program list.
