We have solar credit carried over from 2024 and 2025. Can we still apply credit to 2026?

Best answer by DoninGA

Yes, you can carry forward unused portions of the residential solar tax credit to 2026 and future years, provided your solar energy system was installed and placed in service by the deadline of December 31, 2025.

The tax code allows you to carry forward any excess, unused credit to future tax years until you have claimed the full amount. The IRS has not announced an expiration date for carrying forward the credit, so it is generally considered to be indefinite for qualifying installations.

Yes, you may carry over into 2026. The Solar Credit for NEW residential solar installations officially expired on December 31, 2025, the rules for carrying forward credits you already earned remain in place in 2026.
