Rebates & incentives in Tennessee
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.
Tennessee's IRA Home Energy Rebates are administered by TDEC's Office of Energy Programs (the state energy office); the state's allocation was approved but the consumer-facing HOMES/HEAR programs had not launched as of mid-2026. Check TDEC for current status before promising rebates. See our Kingsport guide for the full program list.
