If an active e-way bill is linked, cancel it first.
What an IRN is—and where you generate one
An Invoice Reference Number (IRN) is assigned after an authorized IRP receives and validates reported invoice details. The IRP digitally signs the invoice and returns it with a signed QR code. The GST system and the IRP interface are related but not the same: taxpayers report invoice data through an IRP, which sends it into the GST system. The official IRIS IRP FAQ explains: “On reporting, IRP will generate a unique ‘Invoice Reference Number (IRN)’, digitally sign it and return the e-invoice with QR code.” Read the IRIS IRP FAQ.

| Route | Best fit | What to know |
|---|---|---|
| Invoice form on the IRP | An occasional single invoice | Enter the invoice details directly in the portal. Screen names and availability can differ by IRP. |
| Offline Excel utility or bulk upload | Preparing a batch of invoices | Use the utility and upload workflow supported by the chosen IRP. Taxpayers without their own ERP or invoicing software can use a portal’s offline utility where available. |
| ERP or accounting-system API integration | An established workflow or recurring invoice volume | Connect the existing system through an IRP’s supported API route; check that IRP’s onboarding and technical requirements. |
The official IRIS IRP resources describe portal and integration options. A taxpayer manual published as a draft on 27 January 2023 contains older interface details, so do not rely on its screenshots as current navigation.
How to cancel an IRN on IRIS IRP
- Sign in to your IRIS IRP account and have the relevant GSTIN available.
- Open Manage > View Invoices.
- Find and select the invoice with the active IRN you need to cancel.
- Choose Cancel IRN.
- Select a cancellation reason and enter a remark. Both are mandatory.
- Submit the cancellation while the IRN is still within 24 hours of generation.
The IRIS help page says the list shows invoices from the past two days by default, but that display range does not extend the cancellation deadline: only active IRNs generated within the preceding 24 hours are eligible. See IRIS IRP help. Other IRPs may use different menu labels.

The 24-hour window
The IRP allows cancellation only within 24 hours of IRN generation. If the deadline has passed, the IRP will not cancel the IRN. The 24-hour period is an operational rule, not a rolling extension based on when you view the invoice. Confirm the current official guidance if you are acting later than the guidance date.
An active linked e-way bill
If an active e-way bill is associated with the invoice, cancel that e-way bill before submitting the IRN cancellation. The official IRP FAQ describes this dependency.

An IRP does not provide an in-place amendment facility for invoice details already reported. While the cancellation window remains open, cancellation is the route for correcting an invoice that should not stand as reported; then report the correct invoice as applicable. Do not assume that the cancelled IRN can be reused.
What to do if the 24-hour window has passed
Once the 24 hours have elapsed, do not keep trying to cancel through the IRP: the IRN is no longer eligible for cancellation there. The official FAQ points taxpayers to make necessary changes in GSTR-1 as appropriate and cites a credit note for relevant cases. Which treatment applies depends on the facts and applicable GST rules; an IRP cancellation and a GST return or accounting correction are not interchangeable. Review the transaction with your tax adviser or refer to current GST guidance before choosing a correction.
Cancellation does not erase the fact that the e-invoice was generated. The cancelled IRN cannot be reused for another invoice, so keep the cancellation details with the related invoice and accounting records.
