Frequently Asked Questions: E-invoice Cancellation
1. How to modify or change e-invoice?
Once an e-invoice is generated, the values cannot be amended or edited. As per GST Rules, an Invoice once prepared cannot be modified.
2. Can I cancel an e-invoice?
Within 24 hours of e-invoice generation, an e-invoice can be canceled.
3. Can the e-invoice be deleted?
No. Once an e-invoice is generated, it cannot be deleted.
Note – Deleting the e-invoice from the GSTZen Sales register will not cancel the e-invoice.
5. Can I use the same e-invoice number when I create the new invoice after cancellation?
No. IRN is unique to each e-invoice. It isn’t possible to generate multiple IRNs for the same Doc No. in a particular Financial Year. Once the IRN is generated, a subsequent request to generate an IRN with the same request will throw an error saying duplicate IRN. A new IRN will be generated for the new e-invoice created.
6. Can I revoke a canceled e-invoice?
No. Once an e-invoice is canceled, it cannot be undone. A new e-invoice has to be created in its place with a different document number.
7. What can I do after 24 hours of generating an e-invoice?
E-invoice cannot be canceled after 24 hours. You can issue a credit note and report it in GSTR-1 along with the E-invoice details.
8. I found a mistake in the e-invoice after 24 hours and cannot cancel it now, what should I do?
There are 2 options
Option 1 – Generate a credit note against the invoice and create a new invoice with the correct information.
Option 2 – Cancel the invoice in your books and do not report it in GSTR 1 while filing. Create a new invoice with the correct information.
