And the current turnover limit required for e-invoice generation is Rs. 50+ crores. The chances are no less that it becomes compulsory for every business to file digital invoices.

What is E-invoicing in GST? 

E-invoicing under GST is exchanging the invoice bill between supplier & buyer in an authenticated & integrated “electronic format.” The introduction of the concept was to replace the conventional paper-based manual process and reduce tax evasions. Under the system, all the registered businesses in India have to generate their unique invoice reference number (IRN) on Invoice Registration Portal (IRP).  

Invoice Reference Number

Invoice reference number (IRN) is a unique 64 characters hash based on four parameters. It includes document number & type, supplier GSTIN, and financial year. Some notable features of IRN are:

  1. Firstly, The GST system’s Invoice Registry saves the Invoice Reference Number generated by the IRP portal;
  2. It is different from Invoice Number;
  3. Generation of e-invoice should be before the movement of goods or issuance of the invoice;
  4. And, the generated IRN remains on the portal for two days.

Applicability of E-invoice under GST

The amendment for making E-invoicing mandatory has been introduced in different phases, based majorly on the aggregate turnover value of the business. The first phase went live in October 2020, when the government made digital invoicing mandatory for all companies with an annual turnover of more than Rs. 500 crore. 

The second phase went live on 1st January 2021, when the government mandated the invoice filling for businesses having an AATO of INR 100+ crores.

Similarly, the third phase went live on 01st April 2021. Now, the organizations with an AATO of more than Rs. 50 crores are required to make digital invoices.

Note 1: The only seller can generate e-invoice and not the receivers, transporters, or customers. However, eCommerce platforms need to create invoices on behalf of their suppliers.  

Note 2: E-invoice under GST to be calculated from FY 2017-18, and respective aggregate annual turnover businesses need to comply. 

Note 3: E-invoice under GST needs to be generated only for B2B  & Export bills and not for B2C bills.

How to Generate E-Invoice GST?

Here are steps by step guide to generate E-invoice under GST :

Step 1: All the businesses need to create E-invoices on their accounting portals. However, they need to ensure that all the required fields are mentioned and in the proper format. If the case fails, then the invoice would be held invalid.

Step 2: Getting approved through the government E-invoice portal – IRP (Invoice Registration Portal), is a government portal, where every registrar registers and gets an IRN (Invoice Registering Number). IRN is a unique identification number for each invoice, generated by registered firms once an invoice is authorized. 

Step 3: Once a business registers for E-invoice under GST, the IRP portal would generate a digitally signed QR code with specific details from the invoice. The digitally signed QR code shall be printed on the invoice too. 

After this process, e-invoice would be authenticated, and all the related information gets mentioned on the government’s EWB portal.
