GSTN Clarifies Table 12A Issue in GSTR-1 for B2C Transactions

Last updated: 14 July 2025


Quick Summary
Taxpayers solely dealing with Business-to-Consumer (B2C) supplies have encountered an error when filing their GSTR-1 if Table 12A (HSN Summary for B2B supplies) is left blank, especially when Table 8 contains entries. GSTN has provided a temporary solution: enter a dummy HSN code and UQC with all other fields as '0' in Table 12A. System enhancements are also in progress to permanently resolve this issue.

In a recent clarification concerning Table 12 of GSTR-1, particularly the HSN summary of outward supplies, taxpayers dealing exclusively in B2C supplies have reported issues with Table 12A when left blank. While Table 12B (pertaining to B2C transactions) is not mandatory and can be left blank or filled with any value, complications arise when there are no B2B supplies reported in Table 8 but at least one entry is made in Table 8.

GSTN Clarifies Table 12A Issue in GSTR-1 for B2C Transactions

The Issue

Several taxpayers with only B2C transactions are facing difficulties filing their GSTR-1 when Table 12A (HSN Summary for B2B supplies) is left empty, especially in cases where Table 8 (nil-rated, exempted, or non-GST supplies) has any entry. The system throws an error, creating confusion for filers and resulting in delays.

The Interim Solution

To address this issue, the authorities have advised a simple workaround:

  • Taxpayers must ensure that Table 12A is not left completely blank.
  • Even if there are no B2B supplies, they can enter any HSN code and UQC (unit quantity code) and fill all other fields with "0".
  • This dummy entry will allow the system to process the return without generating an error.

The Goods and Services Tax Network (GSTN) has also announced that system enhancements are underway to resolve this issue permanently. Once implemented, the GSTR-1 filing process for taxpayers dealing solely with B2C supplies will be simplified, eliminating the need for such workaround entries.

Key Takeaway

Taxpayers are urged to remain updated and use the advised workaround in the meantime to avoid disruptions in GSTR-1 filing. The CBIC and GSTN continue to monitor system behavior and are working towards a more intuitive and error-free experience for all users.
