The Goods and Services Tax Network (GSTN) has recently issued an advisory regarding significant changes to Table-12 of GSTR-1 and GSTR-1A, effective from the tax period of April 2025. These updates are part of the Phase-III rollout aimed at streamlining GST return filings and enhancing data accuracy. Here's a detailed breakdown of the changes and their implications for taxpayers.

What is Table -12 of GSTR-1 and GSTR-1A?
Table-12 is a section in the GST return forms where taxpayers report the summary of their supplies based on Harmonized System of Nomenclature (HSN) codes. This table plays a crucial role in ensuring uniformity and transparency in tax reporting.
Key Changes in Table -12
1. Split reporting for B2B and B2C Transaction:
Table-12 has been bifurcated into two separate sections:
* Business to Business (B2B) Transactions
* Business to Consumer (B2C) Transactions
Taxpayers must now report the summary of their supplies HSN wise in the respective sections.
2. Mandatory HSN Code Section Transaction:
- Manual entry of HSN codes is no longer permitted.
- Taxpayers are required to select the appropriate HSN code from a pre-defined dropdown list provided within the GSTR-1 or GSTR-1A forms.
Benefits of the Changes
- Improved Accuracy: The dropdown-based HSN selection minimizes the risk of errors in reporting.
- Enhanced Compliance: Clear segregation of B2B and B2C transactions simplifies compliance for taxpayers.
- Streamlined Audits: Accurate HSN data facilitates smoother audits and analytics.
Steps to Ensure Compliance

- Review the detailed advisory issued by GSTN on January 22, 2025, available on the GST Portal.
