Rebates & incentives in Florida
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.
Florida declined IRA Home Energy Rebate funding entirely — there is no state-run HOMES/HEAR program. Window incentives in Florida come from utilities, insurance premium credits for wind mitigation, and hurricane-hardening value rather than rebates. See our Port St. Lucie guide for the full program list.
