What is a GST E-Invoice?

A GST e-invoice is a digitally reported tax invoice generated via the Invoice Registration Portal (IRP) and assigned a unique Invoice Reference Number (IRN). It is mandatory for  GST -registered businesses exceeding a certain turnover threshold for B2B transactions.

E-invoicing ensures seamless flow of invoice data into returns,  e-way bills , and other government systems.

Why You Might Need to Cancel or Amend an E-Invoice

  • Incorrect buyer GSTIN or invoice details
  • Duplicate invoices for the same transaction
  • Wrong taxable amount or GST rate selected
  • Order cancellation after invoice generation

Since IRP does not support direct editing of invoices, errors must be resolved via cancellation,  credit notes , or amendments in  GSTR-1 .

Steps to Cancel a GST E-Invoice (Within 24 Hours)

  • Login to IRP or your  GST billing software
  • Navigate to “Cancel E-Invoice”
  • Enter the IRN or acknowledgment number
  • Select the reason for cancellation
  • Submit and download the confirmation

Note: After 24 hours, IRP does not allow cancellation. You must handle corrections via credit notes or return amendments.

What If the 24-Hour Window Expires?

In such cases, follow one of these alternatives:

  • Cancel in Your Books: Mark the invoice as cancelled in your internal records.
  • Issue a Credit Note: Create a credit note referencing the incorrect invoice to nullify its impact.

This maintains your tax compliance and allows you to issue a corrected invoice with a new number.

How to Amend Invoices Using GSTR-1

  • Login to GST portal
  • Navigate to GSTR-1 → Amendment section
  • Select the invoice to be updated
  • Edit the relevant fields (GSTIN, amount, date, item details)
  • Save and submit your amended return

This process ensures your buyer sees the correction in GSTR-2A or GSTR-2B.
