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.
When and Why You 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.
How to Correct an E-Invoice After 24 Hours?
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.
- 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.
