Federal Solar Tax Credit Expired Dec 31, 2025

The federal 30% residential solar tax credit (Section 25D) expired December 31, 2025 under the One Big Beautiful Bill Act. Homeowner-owned systems installed in 2026 or later do not qualify for this federal credit. If your system was fully installed on or before December 31, 2025, you may still be able to claim it on your 2025 taxes — consult a tax professional. State and utility incentives are unaffected by this change. Use our Tax Credit calculator to check your eligibility.
