Invoice correction in GSTR - 1

[Rajat Gupta]

IN JUNE GSTR 1, I WAS SUPPOSED TO SHOW ONLY 1 INVOICE DATED 30.06.2026. BY MISTAKE, I REPORTED 2 INVOICES IN THE CONTINUED SERIAL NO. AS 1 & 2, BOTH DATED 30.06.2026. I REALISED THIS AT THE TIME OF FILING RETURN ON 11.07. THE ISSUE IS THAT I HAVE ISSUED INVOICE WITH SERIAL NO. 2 FROM 01.07. AND SO ON. HOW CAN I CORRECT THIS ERROR SO THAT THERE IS NO HINDERANCE AT THE TIME OF FILING GSTR 1 OF JULY?

Dear Querist

You may change the no. of the invoice from 2 to 3 (or whatever number you wish to incorporate) and issue a credit note for the same in GSTR-1A. If the recipient is unregistered - nether further need be done. If the recipient is registered please coordinate to ensure that the revised invoice no. and related credit note is accepted by the recipient. GSTR-1A must be uploaded on or before filing of GSTR-3B.

The other option is to amend the invoice with an addendum credit note in GSTR-1 of July 2026.

Amend that particular invoice number to say 1A or so in GSTR-1.

Are you not required to issue e-invoice? if not then not much of an issue.

[Rajat Gupta]

Yes did the same. Thank you

AI Summary

GSTR-1 invoice-number correction can use invoice amendment or a corresponding credit note to maintain serial continuity.
GSTR-1 invoice-number correction may be made by amending an erroneously reported duplicate invoice number, including by using an alphabetic suffix, to address a serial-number mismatch in later reporting. An alternative is to revise the invoice number and report a corresponding credit note through GSTR-1A before filing GSTR-3B. Where the recipient is registered, acceptance of the revised invoice and related credit note should be coordinated; amendment in the subsequent month's GSTR-1 with an addendum credit note is also mentioned.
