Rebates & incentives in South Carolina
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.
South Carolina's IRA Home Energy Rebates are administered by the South Carolina Energy Office (within the Office of Regulatory Staff); the HOMES and HEAR allocations are approved but, as of mid-2026, the consumer-facing programs had not launched, with the Energy Office still finalizing software and contractor enrollment after repeated delays. Windows generally qualify only through the whole-home HOMES modeled-savings track rather than as a standalone item. Confirm current status with the SC Energy Office before promising rebates. See our Hilton Head Island guide for the full program list.
