Rebates & incentives in Arkansas
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.
Arkansas's IRA Home Energy Rebates are administered by the Arkansas Energy Office within the Department of Energy and Environment (E&E); DOE allocated roughly $105M, and the state targeted an early-2026 launch, but as of mid-2026 the rebates were not yet available to households. Windows generally qualify only through the whole-home HOMES modeled-savings track rather than as a standalone rebate. Confirm current status with the Arkansas Energy Office before relying on these rebates. See our Fort Smith guide for the full program list.
