To curb tax evasion and ensure transparency, the government is working to make all pillars of GST more interconnected. One such measure was generating e-way bills using e-invoicing details such as the Invoice Reference Number (IRN).

Read on to learn about the changes in the e-way bill, even though e-invoicing has been made mandatory for a different set of taxpayers.

What is the link between e-way bills and e-invoices?

An e-way bill has two parts:

  • Part A contains invoice details such as the supplier and recipient's GSTIN, invoice number, delivery address, HSN codes, etc. 
  • Part B has transporter details such as transporter ID, vehicle number, etc. 

The taxpayer generates both parts from the e-way bill portal by manually updating the invoice and transporter details.

With the implementation of e-invoicing, the process is partly automated. Details in e-way bills can be auto-populated from the e-invoicing portal, unlike the current system. Once the e-invoice is successfully validated, both parts A & B of the e-way are auto-populated, provided some optional details (transporter ID and mode of transport) in the e-invoice are updated. The motive behind these changes is to simplify creating e-way bills.

Note: The existing users of the e-way bill portal can use the same credentials to log in to the e-invoice portal instead of getting a new registration

There are facilities provided on the e-invoice portal for :

  • Generation of an e-way bill using IRN: A user has to enter the IRN to generate an e-way bill on the e-invoice portal.
  • Bulk generation of e-way bill: The government provides a bulk generation facility for businesses that conduct a large number of daily transactions.
  • Print e-way bill: Under the e-way bill option, a user can select the print EWB option and then enter the e-way bill number. After entering the EWB number, the e-way bill will be displayed with an option to print.

How will e-way bills be generated after the e-invoicing?

There is no change in the process of generating e-way bills. However, an additional facility to generate e-way bills from IRN is provided. A user can follow the steps below:

  • Upload the invoice to the invoice registration portal (IRP).
  • The GSTN verifies the mandatory details, and upon successful validation, the IRP issues a unique number called the invoice reference number and a QR code on the invoice.
  • This data is transferred to the e-way bill portal, where section 12 of the e-invoice schema (e-way bill details) is reported. The APIs are used to generate e-way bills from IRN.
  • A user should then log in to the e-way bill portal and enter the invoice IRN for which they need to generate an e-way bill.
  • Part A and B will auto-populate if the required details are updated in the e-invoice.
  • Click submit. If there are no errors, the e-way bill will be generated, and one can download it as a JSON or PDF file.

Impact of amendment or cancellation of e-invoice on the e-way bill

Currently, there is no provision to address the cancellation of e-way bills through the cancellation of e-invoices. In the case of incorrect invoices, the same errors will also flow in e-way bills. Recently, the NIC clarified that the e-way bills must be cancelled first, followed by the IRN. An e-way bill cannot be generated for a cancelled IRN.

Impact on businesses due to e-way bill integration with e-invoicing

The objective behind the integration of the e-invoicing system with the e-way bill system is to make the entire process easy and automated. Along with this, the government has also linked e-way bills to the GST return filing. The e-way bill generation will be blocked for taxpayers who have two or more consecutive GST returns pending to be filed. These integrations will have the following benefits for the businesses:

  • Easy compliance for the taxpayers.
  • Ensuring accuracy by automating the process.

It will also benefit the government in ensuring reduced tax evasion.

Frequently Asked Questions

Is e-invoicing mandatory and to whom?

e-Invoicing became mandatory for all taxpayers from 1st October 2020, whose aggregate turnover in a financial year exceeded Rs.500 crore. Thereafter, taxpayers with a turnover of more than Rs.100 crore must comply from 1st January 2021 whereas taxpayers with a turnover of more than Rs.50 crore must begin complying from 1st April 2021.

The government extended the e-invoicing applicability to businesses with more than Rs.20 crore turnover w.e.f 1st April 2022. As per the latest update, businesses with a turnover of more than Rs.10 crore must generate e-invoices from 1st October 2022.

Will regular e-way bill generation continue to be allowed instead of generating through IRP?

Yes, regular e-way bill generation will continue along with an additional facility for generating e-way bills with IRN.

How can I generate e-way bills using IRN?

It can be done with the help of API, which will be released shortly.

Will the EWB and IRN systems run independently as of now?

Yes, both the systems will run independently as of now. But, gradually direct EWB generation will be blocked for specified taxpayers.

Is re-generation of EWB and IRN on the same document possible?

Re-generation of EWB on the same document is possible but not for IRN as per policy.

Can an e-Way Bill be generated without an IRN?

Currently, an e-Way Bill can be generated without an Invoice Reference Number (IRN). Although the National Informatics Centre (NIC) had planned to block e-Way Bill generation without IRN from 1st March 2024, this advisory was withdrawn. Therefore, there is no current restriction on generating e-Way Bills without IRN. However, it is recommended to generate both together to maintain consistency.
