Residential Solar Tax Credit Ends as One Big Beautiful Bill Becomes Law
The 30% federal residential solar Investment Tax Credit (ITC) officially ended on January 1, 2026, following the passage of the One Big Beautiful Bill. While residential homeowners can no longer claim the credit for new installations, commercial solar tax credits remain intact, continuing to support large-scale solar deployment and the broader clean energy industry. Homeowners who installed solar before the deadline locked in their credits under the previous law.
