When does the solar tax credit expire?
The federal solar tax credit for customer-owned systems expires December 31, 2025—but solar's long-term value extends far beyond this incentive. Why trust EnergySage? The federal solar investment tax credit (ITC)—Section 25D of the U.S. Tax Code—expires for customer-owned residential solar systems installed after December 31, 2025.
Can I claim a solar system tax credit?
you to claim 30% of the cost of your solar system as a credit to your federal tax bill. For example, if it cost $10,000 to install your solar system, you'd receive a $3,000 credit, which would directly reduce your tax bill.
What does a solar installation tax credit cover?
The credit typically covers solar panels, inverters (including Enphase microinverters), battery storage, wiring, mounting hardware, and installation labor. It may also apply to permitting fees, inspection costs, and sales tax in some states. Always check with a tax advisor to confirm which costs are eligible for your specific installation.
What is the new solar tax credit?
This legislation brings significant changes to the federal tax credit for residential and commercial solar and battery systems. Under this new law, homeowners who purchase their systems with cash or a loan will no longer be eligible for the 30% federal tax credit after December 31, 2025. Previously, this solar tax credit was available through 2034.
