Rebates & incentives in Alabama
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.
Alabama's IRA Home Energy Rebates are administered by ADECA (Alabama Department of Economic and Community Affairs), which as of mid-2026 still lists the HOMES and HEAR programs as under development with no confirmed date for when households can access rebates. If and when they open, windows would generally qualify only through the whole-home HOMES modeled-savings pathway rather than as a direct rebate. Confirm current status with ADECA before relying on it. See our Decatur guide for the full program list.
