25C Energy Efficient Home Improvement Credit — by the numbers
2023 IRS data, most recent full-year statistics available

Congress killed the Energy Efficient Home Improvement Credit after December 31, 2025 — but if you installed a heat pump, new insulation, efficient windows, or a high-efficiency HVAC system any time in 2025, you can still claim up to $3,200 on your 2025 return. This issue covers exactly who qualifies, which form to file (Form 5695 Part II), the deadline, and the average amount claimed.
