Extentions
No extensions, no exceptions, no do-overs. The safe harbor window that could have stretched the timeline closed on July 4, 2026.
July 4, 2026 - Safe Harbor Deadline
The window to lock in extended timelines has closed. What's left is the final placed-in-service deadline.
Today (You Are Here!)
The final window is open. Projects that start now finish comfortably inside it.
Late 2026
The last comfortable window to start a project and still leave room for permitting and interconnection.
Mid 2027
Starting now means racing permits, installer schedules, and equipment supply — with no margin for delays.
December 31, 2027
Systems not running by midnight lose the 30% credit. Permanently.
Psst — battery storage runs on a different clock.
The 2027 deadline applies to solar and wind only. Battery energy storage keeps its full 30% federal tax credit through 2033. Get solar in under the wire — and know your storage options stay open longer.
