Undo IRN/e-Invoice Cancellation in TallyPrime: 4 Steps + Example

Once you cancel an IRN in TallyPrime, you may sometimes realize that the cancellation was done by mistake.

Can you undo the cancellation?
No, you cannot undo an IRN cancellation on the IRP (Invoice Registration Portal) after the 24-hour window is closed.

However, if you mistakenly cancelled the IRN within TallyPrime only (and not on the IRP), you can undo the cancellation locally in TallyPrime and regenerate the IRN.

Let’s understand both scenarios.

1. Scenario 1: IRN Cancelled on IRP (Portal)

If you already sent the cancel request to IRP and got the success message, then the IRN is permanently cancelled.

1. In this case:

You cannot undo the cancellation.
You must create a new invoice and generate a new IRN.

2. Example:

You generated an e-Invoice on 15th July.
You cancelled the IRN the same day on the portal via Tally.
You realize later that it was correct and shouldn’t have been cancelled.

In this case, you need to:

Create a new invoice (with same or corrected details)
Generate a fresh IRN from TallyPrime

2. Scenario 2: IRN Cancellation Done Only in TallyPrime (Not Sent to IRP)

Sometimes, you might cancel the IRN only inside TallyPrime, and the request never went to the IRP.

In this case, you can undo the cancellation locally and reattempt IRN generation.

1. Steps to Undo IRN Cancellation in TallyPrime (Local Undo)

Let’s go step-by-step:

1. Step 1: Open e-Invoice Report

Go to:

Gateway of Tally > Display More Reports > Statutory Reports > GST > e-Invoice > e-Invoice Report

2. Step 2: Check ‘Pending’ or ‘Rejected’ Tab

If the IRN was not cancelled on IRP, it may show under these tabs.

If it’s in “Rejected by IRP” or “Pending” tab, the cancel request hasn’t gone through
This means it’s still valid and can be used to generate IRN

3. Step 3: Mark IRN as ‘Not Cancelled’

If you manually marked the voucher as cancelled in Tally but didn’t send the request to IRP, then:

Open the voucher
Remove the cancellation flag or cancel remark (if used)
Press Ctrl + I > More Details > check for any IRN status changes

4. Step 4: Generate IRN Again

Now go to:

Gateway of Tally > Transactions > e-Invoice > Pending for IRN Generation

Select the invoice and press:

Alt + Z > Generate IRN

2. Example: Undoing Local Cancellation in TallyPrime

Let’s say:

Invoice No: INV/1002
IRN not yet sent to IRP
You pressed “Cancel IRN” by mistake in Tally

Then you can:

Open the voucher
Make it active again (remove any “Cancelled” tag)
Regenerate the IRN

If the invoice was altered in between, correct it before regenerating.
