Yes, ITC from a prior month invoice can be claimed in a later GSTR-3B, as long as the invoice shows up in your GSTR-2B and you claim it before the annual cutoff under Section 16(4). That cutoff is the earlier of: the September return filing of the next financial year, or the filing of your annual return. With IMS active, if the supplier files their GSTR-1 late, your GSTR-2B for that month will not reflect the invoice. It will appear in the next month GSTR-2B once the supplier has filed.
You can then accept it through IMS and it flows into your GSTR-3B table 4 for that period. Do not manually claim ITC not yet in GSTR-2B, as the portal now enforces a hard block on excess ITC beyond your GSTR-2B entitlement.
