Dear all,

Due to some error, we forgot to upload credit note issue by us in GST return of Januaryy filed in February. We got to know only when our client informed us.

Please tell us if we can upload this in this month's return with back dated credit notes ? If yes..how ?

Quick Summary

If you've forgotten to upload a GST credit note in a previous return, don't worry. You can include it in your next GSTR-1 filing, provided you are within the statutory time limits. Ensure you correctly enter the original invoice details on the credit note and inform your buyer that their Input Tax Credit (ITC) will reflect in the period you upload it, not the original issue month.

Yes, you may add the missing credit note in the next return that is due to be filed.

Credit notes do not have to match the same GSTR-1 period as the original invoice. You can upload a credit note issued in an earlier month in any subsequent GSTR-1, as long as you stay within the time limit.

The deadline for FY 2025-26 credit notes is November 30, 2026 (or before GSTR-9 filing, whichever comes first). So you can include the missed credit note in your September 2026 GSTR-1, due October 11.

Two things to keep in mind: (1) enter the original invoice date and number correctly in the credit note, and (2) your buyer GSTR-2B will show it only in the period when you upload it (not the original month), so let them know to reverse ITC from that period.
