E-Invoicing under GST is notified vide notification no. 68/2019 - Central Tax. It is a concept of submission of already generated invoice on a common e-invoice portal where authentication of invoices is checked in Invoice Registration Portal (IRP) resulting in generation of identification number against every invoice.

E-invoice is not applicable to every business; the applicability of the same is based on turnover of business.

By using this concept tax authorities will have to access transactions and it was implemented from 1st Oct 2020.

Let’s understand in detail the e-invoicing system and its limit under GST.


    What is the E-Invoicing System under GST?

    E-invoicing (Electronic invoicing) is a system in which your invoices will be electronically authenticated by GSTN.

    E-Invoicing under GST (Applicability from 1st April, 2021)

    It covers B2B invoices (i.e. supplies mode to registered person). For this process electronically authentication invoices registration portal (IRP) is developed.

    Under this IRP portal, invoices are electronically authenticating and an identification number will be issued against each invoice.

    The benefit of e-invoicing is that once the IRP authenticates the invoices then it will transfer all the invoice information to GST portal as well as e-way bill portal.

    So as a result you do not need to enter the data in GSTR-1 manually it will be filled automatically.

    In this way Invoice Registration Portal (IRP) will share information with GST Portal as well as E-way bill portal.

    What is the applicability of e-invoicing under GST?

    Applicability of e-invoicing is decided by aggregate turnover. E-invoicing made applicable from 1st Oct 2020 to businesses having aggregate turnover exceeds Rs.500 Crore in any of the preceding financial years from 2017-18 to 2019-20.

    Later on this limit of Rs. 500 crore is decreased to Rs.100 crore.

    On 8th March 2021, Notification No. 5/2021-Central Tax, CBIC notified that e-invoicing will be applicable from 1 April 2021 for businesses whose aggregate turnover is any financial year from 2017-18 onwards, exceeds Rs.50 crore. Now this turnover limit is Rs.20 crore which is applicable with effect from 1st April 2022. The limit decreased from Rs.50 crore to Rs.20 crore by notification number 1/2022-Central Tax.

    So, now for the applicability of e-invoicing turnover limit is Rs. 20 crore.


    What is the current turnover limit for issuing e-invoicing under GST?

    Current turnover limit for issuing e-invoicing is Rs. 20 crore (w.e.f. 1st April, 2022). So, turnover limit will be applicable exceeding the limit Rs. 20 crore for issuing e-invoice.

    • Insurer or Banking Company or a Financial Institution (including NBFC)
    • GTA (Goods Transport Agency)
    • Registered person who is involved in supplying passenger transportation services.
    • Registered person who is involved in supplying services by way of admission to the exhibition of cinematographic films in multiplex services.


    What is the process of e-invoice under GST?

    The process of e-invoice is similar to already issuing invoices. In normal scenarios, we generate invoices through software (Like. Tally) and then upload the details in GSTR 1.

    And if there is a consignor or transporters then he must generate e-way bills by importing the invoices in excel or JSON manually.

    But with the e-invoices this generating and uploading invoice will remain the same. This will be done by importing from excel or JSON or via API integration.
