GSTR-3B Autofill Facility

Updated on :  

08 min read.

The GSTN has introduced a facility for auto-population of details into GSTR-3B from GSTR-1 and GSTR-2B from 4th September 2020.

Applicability of GSTR-3B autofill facility

The GSTR-3B autofill facility is made available for normal taxpayers, SEZ units, SEZ developers, and the casual taxable persons filing monthly GSTR-1. The PDF of Form GSTR-3B will be available on the GSTR-3B dashboard once the taxpayer files GSTR-1. This facility will be available for quarterly filers at a later date. The same is available on the GSTR-3B dashboard on the GST portal.

Date of availability of the GSTR-3B autofill facility

This facility is available from the tax period of August 2020 onwards. It means the PDF statement of GSTR-3B for August 2020 will contain auto-generated figures from the respective GSTR-1 and GSTR-2B. 

Source of auto-population of details into GSTR-3B

  1. Output liability: Tables 3.1 & 3.2 of Form GSTR-3B other than Table-3.1(d) related to inward supplies liable to reverse charge are auto-generated by the system based on details updated in GSTR-1 for the tax period.
  2. Input Tax Credit (ITC): The details of ITC and inward supplies liable to reverse charge, which is to be reported in Tables 4 and 3.1(d) of GSTR-3B, are auto-generated the system from Form GSTR-2B for the tax period.

Note: The values generated in auto-generated GSTR-3B are not final. The taxpayer can verify the details before filing and make changes, if any.

Contents of the GSTR-3B autofill or the system generated GSTR-3B

The auto-filled GSTR-3B will contain values in Table 3 from the already filed GSTR-1. The following tables will be auto-populated:

  • Table 3.1(a): Outward supplies- other than zero-rated, nil rated and exempted
  • Table 3.1(b): Outward supplies- zero-rated
  • Table 3.1(c): Other outward supplies- nil rated, exempted
  • Table 3.1(e): Non-GST outward supplies
  • Table 3.2: Supplies made to unregistered persons
  • Table 3.2: Supplies made to composition taxable persons
  • Table 3.2: Supplies made to UIN holders
  • Table 3.1(d): Inward supplies liable to reverse charge from GSTR-2B
  • Table 4A: ITC available from GSTR-2B
  • Table 4B: ITC reversed from GSTR-2B

But if negative numbers are reported in GSTR-1, then such figures would be mentioned as zero in the PDF statement of GSTR-3B.
