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 IRS Section 25C credit provides up to $3,200 per year in federal tax credits for qualifying home energy efficiency improvements. Credits include up to $2,000 for heat pumps and heat pump water heaters, $1,200 for insulation, windows, doors, and energy audits, and separate limits for each category. The credit is non-refundable but renewable annually for installations completed by December 31, 2025.
