If you've missed reporting a debit note from your supplier in your GSTR-3B and GSTR-1 filings, don't worry. You can still report these in your current month's returns. Ensure you reverse any previously availed Input Tax Credit (ITC) if applicable, especially if you haven't already claimed ITC for the debit note.

I got a debit note from my supplier but I missed to report it in GSTR-3B and GST-1. How can I rectify it. I am using Zoho accounting software.
