The Finance Act 2022 inserted Section 16(2)(aa) into the CGST Act, 2017, making GSTN-matching mandatory for Input Tax Credit claims. ITC is only admissible when the supplier's invoice appears in your GSTR-2B — which only populates after the supplier files GSTR-1.
A supplier with even one month of GSTR-1 non-filing puts your ITC at risk of reversal under Rule 86A, with interest at 24% p.a. Regular filing checks before processing invoices protect your working capital.
