Frequently Asked Questions


1. What details will be displayed for the auto-populated e-invoices?

    The item-level details in the document will be aggregated at rate-level for the purpose of auto-population into GSTR-1. For the auto-populated invoices, below additional details will also be displayed.
    1. – Source (e-Invoice)
      – Invoice Reference Number (IRN)
      – Invoice Reference Number Date (IRN Date)

2. What is the basis for auto-population?

The invoices are auto-populated on the basis of the invoice date as reported to the IRP. For example, if a document dated 31 Jan 2021 is reported to IRP on 2 Feb 2021, it will be auto-populated in GSTR 1 of January.  The transactions are reflected in an incremental manner on a T+2 days basis i.e. the e-invoice gets populated in GSTR 1 within two days of its generation.

Note: Auto population stops after GSTR 1 has been filed. Any invoices reported to IPR for a period for which GSTR 1 has already been filed will not get auto-populated anywhere.

3. Is it possible to edit the details of auto-populated e-invoices in GSTR 1?

Details of e-invoices auto-populated in GSTR-1 can be edited/deleted by the taxpayer. However, in such cases, the ‘Source’, ‘IRN’ and ‘IRN date’ fields will be reset to blank in respective tables of GSTR-1. The edited documents will be treated as if they were not auto-populated but uploaded separately by the taxpayer.

Note: If there are more than 500 invoices in a section, the details of a particular invoice cannot be edited or updated. The taxpayer will have to delete the entire section and upload the correct data for the entire section.

4. Is it possible to upload sales invoices with IRN to GST Portal?

    No, IRN will only be displayed against the invoices which have been auto-populated in GSTR 1.
