A taxpayer asked how to report a missed FY 2025-26 tax invoice. The discussion clarified that missed invoices can be added in a later GSTR-1 using the original invoice date, with tax paid through GSTR-3B along with applicable interest, subject to the statutory correction deadline.

To upload a missed invoice from FY 2025-26, add the invoice details to the current month's GSTR-1 (using the original invoice date). Pay the corresponding tax liability in the current month's GSTR-3B, along with 18% p.a. interest calculated from the original due date to the actual date of payment. This is legally permitted as the November 30, 2026 deadline for FY 2025-26 rectifications has not yet passed.
