10. Proposed Changes – linking of GSTR 1 and GSTR 3B

The government plans to scrap the  new returns format proposed last year and streamlining the existing GSTR-1 and GSTR-3B returns. The new return system was supposed to be launched on 1 October this year.

The existing GSTR 1 form, which captures sales-related information, will be more detailed. The Form GSTR 3B, which gives the tax computation, will be auto-populated. Auto-calculation of liability in GSTR 3B will be based on the data furnished in GSTR 1 . It will reduce the  chances of difference between GSTR 1 and GSTR 3B

The GSTN is also looking to reduce errors on part of taxpayers by improving the process of linking GSTR1 with GSTR3B and GSTR2A data with GSTR3B for the flow of ITC.
