Washington Heat Pump Tax Credit 2025
How the federal 25C credit applied to Washington homeowners, how it differs from Pacific Power Wattsmart rebates, and what expired at the end of 2025.
Is there a Washington 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. Pacific Power Wattsmart 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.
