I have two invoices from the tax period of May 2025 that need to be amended in the July 2025 return.
-
For both invoices, I need to correct the invoice numbers.
-
Additionally, for one of the invoices:
-
The original invoice date was entered as 30 May 2025, but the supply actually pertains to 30 April 2025.
-
The GST rate was incorrectly reported as 18%, whereas it should have been 0%.
-
My questions are:
-
Is it sufficient to report these corrections under the B2B amendment table in the GSTR-1 for July 2025?
-
Since the GST rate is being changed, do I also need to issue and report a credit note for the same invoice?
