Kentucky Heat Pump Tax Credit 2025
How the federal 25C credit applied to Kentucky homeowners, how it differs from LG&E / KU Energy Efficiency Rebates rebates, and what expired at the end of 2025.
Is there a Kentucky heat pump tax credit in 2025?
The federal 25C Energy Efficient Home Improvement Credit expired December 31, 2025. It is not available for new heat pump installations in 2026. If you installed a qualifying heat pump in 2025, you may still be able to claim it on your 2025 federal tax return. LG&E / KU Energy Efficiency Rebates rebates are a separate program and remain available regardless of the federal credit status.

Why contractor quotes can be misleading about tax credits
Is the federal 25C heat pump tax credit still available in 2026?
No. According to the IRS, the 25C Energy Efficient Home Improvement Credit applies to qualifying property placed in service before December 31, 2025. Equipment installed in 2026 does not qualify under current law. If Congress extends or reinstates the credit, the IRS will update its guidance.
Can I still claim the 25C credit if I installed a heat pump in 2025?
If your heat pump was placed in service before December 31, 2025, you may be eligible to claim the 25C credit on your 2025 federal tax return. The credit is non-refundable and capped at $2,000 for heat pumps. Beginning in 2025, the IRS also requires a Qualified Manufacturer Identification Number (QMID). Consult a tax professional.
What heat pump incentives are still available in Kentucky in 2026?
While the federal 25C credit expired December 31, 2025, Kentucky homeowners can still access utility rebates through LG&E / KU Energy Efficiency Rebates (LG&E (Louisville Gas and Electric), Kentucky Utilities (KU)). The LG&E / KU Energy Efficiency Rebates heat pump rebate is up to $400. These utility rebates are separate from federal tax credits and remain available for 2026 installations. Verify current amounts directly with LG&E (Louisville Gas and Electric), Kentucky Utilities (KU) before purchasing.
Is there a Kentucky-specific heat pump tax credit?
Consult a Kentucky tax professional and the Kentucky Energy and Environment Cabinet for current state income tax credit availability. LG&E / KU Energy Efficiency Rebates rebates are separate programs — they are utility or agency rebates, not tax credits.
Can I combine Kentucky utility rebates with other incentives in 2026?
Yes. Kentucky utility rebates from LG&E / KU Energy Efficiency Rebates can typically be combined with: any applicable state tax credits (check with a Kentucky tax professional), low-interest financing programs from your utility or state energy office, and any future federal incentives Congress may enact. The federal 25C credit expired for 2026 installations, but the LG&E / KU Energy Efficiency Rebates rebate (up to $400) remains fully available.
