Applicability of E-Invoice Framework for GST

All about the GST E-Invoice Framework with applicability from the portal

What is the E-Invoice Framework under GST?GST e-invoice is the adoption of the digital invoice for goods and services provided by the business created on the GST portal of the Government. Thought has been paid to the idea of a GST e-invoice generation framework for reducing GST evasion.

The GST officers have come to a conclusion by providing companies with a program that makes it mandatory for them to produce ‘e-invoice’ for each sale on the GST portal of government. This scheme will only apply to those whose turnover rate is above the defined threshold i.e. the government will set a threshold for them. The e-Invoicing (Electronic Invoicing) under GST primary objectives were:

Elimination of fake invoices & fake suppliers

  • Earlier, fake suppliers issued invoices without actual supply
  • Recipients availed fraudulent ITC
  • e-Invoicing ensures invoices are authenticated in real time

Prevention of back-dated invoices

  • Earlier, invoices were generated after audits to inflate turnover
  • e-Invoicing restricts back-dated reporting
  • IRP validations + time limits have curbed this malpractice

Improved GST compliance & data integrity

  • Auto-population of data in GSTR-1
  • Seamless e-Way Bill generation
  • Reduced manual intervention and error

Legal backing: Rule 48(4) of CGST Rules, 2017 (Effective from 1 October 2020), ). e-Invoicing is no longer a procedural formality, it determines invoice validity under GST. Strong ERP integration, internal controls, and reconciliation are essential in FY 2025-26.

IRPs’ position for e-invoicing under GST

After dozens of consultations, E-invoicing was eventually introduced on a voluntary basis for GST registered companies in India from 1 January. The developer of e-invoicing APIs is implemented essentially to submit B2B invoices organized to the GST framework. In fact, real-time transaction invoice monitoring would reduce the risk of last-minute problems due to pendency.

Invoice Registration Portal(IRP) – Apart from other modes, the first Invoice Registration Portal allows for invoice registration on the GST system. API mode

IRP aims to incorporate the e-invoicing program into the company invoicing framework for taxpayers.

  • “The roll-out of e-invoicing would be important for companies with a turnover of more than 500 crs from 1 October onwards.”
  • “Seek to exclude any class of registered persons capturing dynamic QR code and the date to be extended to 01.10.2020 for the introduction of QR code.”
  • “Aim to exclude a certain class of registered individuals from issuing e-invoices and extended to 01.10.2020 the date of e-invoicing.”
  • To the above-mentioned firms, GST e-invoicing is compulsory as of 1 October 2020. Those with turnover up to 100 Crore, voluntary, and trial basis start as per the sources from 1st October 2020.
dynamic qr code gst
  • with effect from 1st October 2020, a supplier whose aggregate turnover exceeds 500 crore rupees in the financial year shall have a Fast Response (QR) code to an unregistered individual (B2C Invoice).
  • The official also gave an example in which if Rs 1,000 is the minimum fixed invoice then there are high chances that the businesses would be able to divide the bills and they will escape the invoice that will be created due to the threshold.

System to produce e-invoice for under the GST E-invoice generation process

The GST e-invoice generation process will be the same as the e-way bill created on the https:/ewaybill.nic.in/portal or the GST payments made on the GSTN portal.

The GST e-invoice generation system will replace the e-way bill produced for the movement of goods as a centralized government platform would be used to generate invoices. The e-way bill is currently only produced for those moving goods which cost more than Rs 50,000.

The official also added that there will be no hassle for companies to file the GST returns after the e-tax invoice generation program kicks off, since the data will be auto-filled invoice wise in the return form.

“We’ll have to review global models led by countries like Latin America, South Korea, and Europe,” the official said. We should also look at ways of motivating businesses to follow the process of producing e-invoices.

Along with the officer’s committee, it is entirely the responsibility of the state, central tax officials, and GST Network Chief Executive to implement the e-invoice under the GST program to reduce the burden of producing invoices and enforcement. The committee is given a deadline by next month to finalize the preliminary report.

The main goal of the generation of e-invoices is to test the evasion of GST. After two years of GST implementation, the government is now pursuing anti-evasion initiatives to boost revenue and enforcement.

Only 20 lakhs fall under the composition scheme from the 1.21 Crore listed firms.

The GST e-invoice generation system would minimize the dual effort, as well as the manual involvement in filing and reviewing tax returns, according to a tax expert.

It said, “The tax department could limit the frequency of mandatory departmental audits in case e-invoice procurements are made to encourage businesses to follow the new framework.”

List of Invoice Registration Portal(IRPs) under GST E-invoicing

Following dozens of discussions, e-invoicing was eventually introduced on a voluntary basis for GST registered enterprises in India from 1 January. E-invoicing or electronic invoicing is implemented primarily for the structured recording of B2B invoices to the GST system. In fact, real-time transaction invoice monitoring would reduce the risk of last-minute problems due to pendency.

The target for Invoice Registration Portal(IRPs)

Invoice Registration Portal(IRP) – In addition to other modes, the first Invoice Registration Portal provides for invoice registration on the GST system via API mode.

IRP aims to incorporate the e-invoicing program into the company invoicing framework for taxpayers.

The portal also lets the taxpayer get credentials he can access APIs from. Registration for the connection to the API will be complete once the OTP is entered on the checked mobile number and email Id.

IRP provides descriptions of the integration of the business processes through APIs into their e-invoice processes.

Code extracts and master data are given to learn the logic and concepts properly.

By understanding and checking the API methods, developers can boost the performance of APIs with the help of the portal.

New e-invoicing update under GST framework

In addition to improving the GST structure, the board has now moved to legitimize a new GST e-invoicing or electronic invoicing in a channelized manner for reporting business to business ( B2B) supplies to the GST scheme. The rule will be voluntary in effect as from 1 January 2020.

As any new rule calls for the establishment of a clear norm to accomplish the target in effect. After consultations with trade/industry bodies and representatives of ICAI, the basic standard for e-invoicing is finalized to ensure the absolute applicability of the existing e-invoicing under the GST regime. There was no set norm for e-invoicing up to now.

The e-invoicing function is guided in such a way that e-invoices created by one software are controlled by software that removes the need to re-enter the digits for a fresh entry. Adoption of this specific standard would allow the seller, buyer, bank, or agent, or any other person concerned to read by a computer and thereby restrict the unnecessary data, minimizing errors. This is the main aim behind improving the e-invoicing GST structure.

For some time, the Department has been requesting reconciliations from businesses, and in such circumstances, this file becomes the most crucial file. It also aids us in gaining a better understanding of all business operations and reconciling data in order to be safe.

It was in the 37th meeting of the GST Council chaired by Union FM Nirmala Sitharaman, the design of the new e-invoice system was discussed and accepted, and the same is released on the GST portal along with the schemes.

E-invoice details are auto-populated in the respective GSTR-1
