Section 16(5) is a retrospective relief provision inserted by Finance (No. 2) Act, 2024.

It protects taxpayers who claimed ITC for FY 2017-18 to FY 2020-21 that would otherwise be blocked by the Section 16(4) time limit (which requires ITC to be claimed by the earlier of: due date of September GSTR-3B or due date of annual return for that financial year).

Practical impact:
- If you received a notice demanding reversal of ITC under Section 16(4) for any of those 4 financial years, Section 16(5) is a specific defense
- The ITC must have been reflected in GSTR-2A for the relevant period and the return must have been filed
- CBIC clarifications have stated this does not reopen all past claims; it protects ITC that was blocked specifically by the Section 16(4) deadline, not for other reasons like non-payment by supplier or ineligibility

If you are dealing with a demand notice for these years, cite Section 16(5) explicitly in your reply.
