ITC with Pre-Construction

The OBBBA Changes Everything

The One Big Beautiful Bill Act (OBBBA) and IRS Notice 2025-42 have reshaped the ITC landscape:

For projects over 1.5 MW, the 5% Financial Safe Harbor no longer applies.

Only the Physical Work Test (= Pre-Construction)  can establish “beginning of construction.”

Each deadline removes key advantages:

  • Sept 2, 2025 → 5% Safe Harbor eliminated for >1.5 MW.
  • Dec 31, 2025 → Last chance to secure 4-year window & FEOC immunity.
  • July 4, 2026 → Lose the 4-year window; projects must be completed by Dec 31, 2027.
  • Dec 31, 2027 → Final cut-off; no ITC for unfinished projects.
