  • A new CI application must be submitted before September 30, 2025, and subsequently approved.
  • Without this submission and approval, no section 90 credit adjustment can be requested.
  • Applications must be accompanied by a verification report prepared by an accredited verification body.

December 31, 2025 – Section 88 Credit Adjustment

  • Applies to credit adjustments for all previous compliance periods (2022–2025).
