Energy Efficient Home Improvement Credit (25C), Federal Tax Credit
IRS / U.S. Department of the Treasury
About This Program
Note: Congress ended this federal tax credit for installations after December 31, 2025. Projects placed in service by that date can still be claimed on your 2025 federal return (IRS Form 5695).
The Section 25C Energy Efficient Home Improvement Credit provides a 30% federal tax credit (up to $3,200/year) for qualifying upgrades including heat pumps ($2,000 sub-limit), insulation, windows ($600 sub-limit), doors ($500 sub-limit), and energy audits ($150). The credit resets each year, and 2025 is the final year to claim it before expiration.
Annual max $3,200; $2,000 for heat pumps/biomass; $1,200 for all other items
