The Central Board of Indirect Taxes & Customs (CBIC) has facilitated the auto-population of e-invoice details into the GSTR-1 return on the GST portal. All taxpayers who issue e-invoices after obtaining the IRN (Invoice Reference Number) from the IRP (Invoice Registration Portal) will get the details of such e-invoices auto-populated in the respective tables of the GSTR-1.

As per advisory dated 30th November 2020, transactions will be reflected in an incremental manner on T+2 day basis, such that within two days, the e-invoice transaction gets autopopulated into the GSTR-1. These e-invoice details can also be downloaded as an excel file.If the GSTR-1 for the respective period was already filed by the taxpayer, then the details from the e-invoices can be downloaded only as an excel file.

Changing details in the GSTR-1: In case e-invoice details are edited by the taxpayer directly in the GSTR-1, then the source, IRN and IRN date fields will be reset to blank in the respective tables of GSTR-1. Such edited documents are considered as separately uploaded by the taxpayer rather than auto-populated.

Review of auto-populated details by taxpayers: Taxpayers can review the auto-populated details of e-invoices by:

Viewing them online on the GST portal
Downloading the JSON from the GST portal
Using APIs via a GSP (GST Suvidha Provider)

Updation of additional details: Taxpayers need to update additional details other than those auto-populated from the e-invoices.

Additional facility: An additional facility of downloading the auto-populated documents is made available to taxpayers on the GSTR-1 dashboard. Taxpayers can click on the ‘Download details from e-invoice (Excel)’ button on the GSTR-1 return form. However, if there are subsequent modifications made to the documents, which were auto-populated in the GSTR-1 tables, then these modifications will not be reflected in the excel file. Taxpayers can also use the link ‘e-invoice download history’ to view the list of the last five downloaded files.

The downloaded file will contain details of e-invoices from the IRP along with following additional information:

Invoice Reference Number (IRN) – 64 string hash
