The federal energy tax credits have expired

Costs and payback figures on this page may still assume a federal credit that no longer exists. The 30% Residential Clean Energy Credit (25D) and the Energy Efficient Home Improvement Credit (25C) both ended for property placed in service after 31 December 2025, and the home EV charger credit (30C) ended after 30 June 2026. Assume no federal credit on work done today.
