Question

ITC for FY 2019-20 was claimed on 31.10.2022. Notice says it is time-barred under Section 16(4). Any solution?

Answer

Section 16(5) likely does not save this ITC because the claim was made after 30.11.2021. Check Section 16(6) only if cancellation/revocation facts exist. If the case is under Section 73, Section 128A waiver may be explored.
