GST Portal - Auto-population of e-invoice details into GSTR-1/2A/2B/4A/6A



Quick Summary
Taxpayers issuing e-invoices can now benefit from auto-population of their invoice details directly into the relevant tables of GSTR-1. This feature, which began for some from December 2020, operates on a T+3 day basis, meaning data uploaded on one day appears in GSTR-1 three days later. While most e-invoices are processed, certain common issues or data structure errors may prevent auto-population, with these details being available in a downloadable Excel file for correction.

1. Certain notified taxpayers have been issuing invoices after obtaining Invoice Reference Number (IRN) from Invoice Registration Portal (IRP) (commonly referred as ‘e-invoices’). Details from such e-invoices shall be auto-populated in respective tables of GSTR-1. Update on the status of such auto-population was last published on 30/11/2020.

2. For those taxpayers who had started e-invoicing from 1-10-2020, the auto-population of e-invoice data into GSTR-1 (of December 2020) had started from December 3rd, 2020.

In this regard, following is to be noted by those taxpayers:

GST E-Invoice Auto-population into GSTR-1/2A/2B/4A/6A

• The data in GSTR-1 is now available on T+3 day basis, i.e. for example, the data from e-invoices uploaded on 18-12-2020 would be visible in GSTR-1 on 21-12-2020.
• The corresponding reflection of such e-invoice details in GSTR-2A/2B/4A/6A has also started.
• The auto-population of e-invoice data into GSTR-1 is based on date of document (as reported to IRP).

For example, a document dated December, 30th, 2020 is reported to IRP on 3rd January, 2021 and where GSTR-1 for December, 2020 is not filed, then the details of that document will be available in the tables of GSTR-1 pertaining to December, 2020.

However, if the GSTR-1 for December was already filed by that date, then, the details of such document will be made available in the consolidated excel file downloadable from GSTR-1 dashboard (with error description as ‘Return already filed’). The taxpayer may thereupon take necessary action.

3. Owing to existing validations in GSTR-1, e-invoices reported with below commonly observed issues are not auto-populated in the tables of GSTR-1 but are made available in the consolidated excel file downloadable from GSTR-1 dashboard (with corresponding error description):

  • • Supplier is found to be of type ISD/NRTP/TCS/TDS;
    • Supplier is found to be composition taxpayer for that tax period;
    • Document date is prior to Supplier’s/Recipient’s effective date of registration;
    • Document date is after Supplier’s/Recipient’s effective date of cancellation of registration;
    • Invoices reported as attracting “IGST on Intra-state supply” but without reverse charge;

4. Further, in certain cases, e-invoice details could not be processed (and hence were not auto-populated) due to data structure issues. These errors may be taken note of and shall be avoided while reporting the data to IRP.

  1. • Serial number of item shall not be reported as ‘0’
    • White space found in POS (Place of Supply State Code), e.g. “8 ” . Expected values were 08 and 8.

5. The detailed advisory with methodology of auto-population etc. is already made available on the GSTR-1 dashboard (‘e-invoice advisory’) and also e-mailed to relevant taxpayers.

6. It is once again reiterated that the auto-population of details from e-invoices into GSTR-1 is only a facility for the taxpayers. After viewing the auto-populated data, the taxpayer shall verify the propriety and accuracy of the amounts and all other data in each field, especially from the perspective of GSTR-1 and file the same, in the light of relevant legal provisions.

7. The taxpayers are once again requested to verify the documents auto-populated in GSTR-1 tables and consolidated excel and may share feedback on GST Self Service Portal, on below aspects:

  1. 1.All documents reported to IRP are present in excel
    2.Status of each e-invoice/IRN is correct
    3.All the details of document are populated correctly

Thanking you,

Team GSTN

FAQ :

The auto-population feature allows details from e-invoices, issued with an Invoice Reference Number (IRN), to be automatically filled into the respective tables of GSTR-1 and other GST returns like GSTR-2A, 2B, 4A, and 6A.

For taxpayers who started e-invoicing from 1st October 2020, the auto-population of e-invoice data into GSTR-1 began from December 3rd, 2020.

The data in GSTR-1 is available on a T+3 day basis. For example, e-invoice data uploaded on the 18th of a month will be visible in GSTR-1 on the 21st of that month.

If your GSTR-1 for a particular month has already been filed, details of newly processed e-invoices for that period will be available in a consolidated Excel file downloadable from the GSTR-1 dashboard, marked with an error description like 'Return already filed'.

Common reasons include the supplier being an ISD, NRTP, TCS, or TDS entity; the supplier being a composition taxpayer; document dates being inconsistent with registration or cancellation dates; or invoices incorrectly showing 'IGST on Intra-state supply' without reverse charge.

After viewing the auto-populated data, taxpayers must verify its propriety and accuracy in each field, especially concerning GSTR-1 requirements, before filing the return.
