IRN Cancellation

IRN Cancellation

E-Invoice Cancellation Steps

1. Purpose

The purpose of this procedure is to outline the steps and guidelines for cancelling an issued Electronic Invoice (E-Invoice) in cases where errors are identified or a transaction is voided. This ensures compliance with regulatory requirements and maintains accuracy in financial documentation.

2. Scope

This SOP applies to all users responsible for generating and managing E-Invoices within the organization using the Cygnet Portal.

3. Overview

E-Invoice cancellation refers to the process of revoking or voiding an issued electronic invoice. It is essential for rectifying errors or addressing cancelled transactions. This process helps maintain data integrity and supports accurate reporting to the government portal.

4. Key Benefits

  • Efficient correction process: Reduces time and effort required to fix invoicing errors.

  • System integration: Seamlessly integrates with financial and ERP systems to automate the cancellation process.

  • Regulatory compliance: Ensures timely cancellation within government-mandated timelines.

5. Key Guidelines

  1. Cancellation Time Limit:

    • The Invoice Reference Number (IRN) can only be cancelled within 24 hours of generation.

  2. E-Way Bill Condition:

    • IRN cancellation is not permitted if an active E-Way Bill (EWB) is linked to the invoice.

  3. Partial Cancellation:

    • Partial cancellations are not allowed; the entire IRN must be cancelled if required.

  4. Beyond 24 Hours:

    • If more than 24 hours have passed, consult your business or compliance team for the next course of action.
      Ideally, issuing a credit note is a workaround.
