Idaho Heat Pump Tax Credit 2025
How the federal 25C credit applied to Idaho homeowners, how it differs from Idaho Power Rebates rebates, and what expired at the end of 2025.
Is there a Idaho 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. Idaho Power 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 Idaho in 2026?
While the federal 25C credit expired December 31, 2025, Idaho homeowners can still access utility rebates through Idaho Power Rebates (Idaho Power, Rocky Mountain Power (Wattsmart Homes), Avista Utilities). The Idaho Power Rebates heat pump rebate is up to $800. These utility rebates are separate from federal tax credits and remain available for 2026 installations. Verify current amounts directly with Idaho Power, Rocky Mountain Power (Wattsmart Homes), Avista Utilities before purchasing.
Is there a Idaho-specific heat pump tax credit?
Consult a Idaho tax professional and the Idaho Office of Energy and Mineral Resources for current state income tax credit availability. Idaho Power Rebates rebates are separate programs — they are utility or agency rebates, not tax credits.
Can I combine Idaho utility rebates with other incentives in 2026?
Yes. Idaho utility rebates from Idaho Power Rebates can typically be combined with: any applicable state tax credits (check with a Idaho 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 Idaho Power Rebates rebate (up to $800) remains fully available.
