Tax on the missed invoices is payable in the month they are reported, with 18% interest under Sec 50(1) from the original due date. Under current rules you can also add them through GSTR-1A for the same period before filing that month's GSTR-3B, and no addition is allowed after 30 Nov following the FY end.
