Transition to New GST Returns

Introduction of new GST return forms

The GST Council decided in their 37th meeting to introduce the new return forms from April 2020 filing period.


The second aspect of transition concerns how to report old invoices, pay liability, or claim ITC on invoices issued prior to the introduction of the new return forms. The table below lists various scenarios where a tax payer could have missed reporting Invoices in their GSTR 1 or missed reporting liability in their GSTR 3B. The table explains how the tax payer shall remedy such instances.

Document Type Document reported in GSTR-1 Liability reported in GSTR-3B Action to be taken
Invoice or
Credit Note
No No Add Invoice to GST ANX-1.
GST RET-1 Table 3A will automatically include the liability.
GST RET-1 Table 6(1) will automatically include interest on the liability.
Invoice Yes No Report liability in Table 3 A(8) of GST RET-1.
Report interest in Table 6(4) of GST RET-1.
Invoice No Yes Add Invoice to GST ANX-1.
GST RET-1 Table 3A will automatically include the liability.
Reduce liability in Table 3 C(5) of GST RET-1.
GST RET-1 Table 6(1) will automatically include interest on the liability.
Forgo the interest since there is no way to reduce it.
Credit Note Yes No Reduce liability in Table 3 C(5) of GST RET-1.
Credit Note No Yes Add Credit Note to GST ANX-1.
GST RET-1 Table 3C will automatically reduce the liability.
Correspondingly increase liability in Table 3 A(8) of GST RET-1.

A similar issue arises when

  • A recipient has not claimed ITC for Invoices issued prior to the introduction of the new return forms
  • The supplier reports invoices pertaining to Tax Period prior to the introduction of the new returns format in their GST ANX 1.

The table below shows what action the tax payer can take in such instances.

Invoice Seen in GSTR-2A Not claimed in GSTR-3B Claim ITC in Table 4 A(4) of GST RET-1.
