Mandatory HSN in Table 12 and Document Reporting in Table 13 of GSTR‑1 Is Now Live — Seamless Support in TaxPower GST

As part of its phased reforms, GSTN has enforced significant changes to GSTR-1 filing — particularly in HSN Table 12 GSTR-1 and Table 13. Taxpayers must now report HSN codes more systematically and provide a comprehensive document list. These updates, implemented via GSTN Advisory No. 597 (dated May 1, 2025), are already active on the GST portal and fully operational within the TaxPower GST Software.

🔍 What GSTN Advisory No. 597 Introduced

The GSTN, via GSTN Advisory  597, mandated improvements to the way taxpayers report their outward supplies:

  • Table 12: HSN can be added only through drop down list. — separate fields for B2B and B2C.
  • Table 13: Mandatory entry of document types and counts, including invoices, credit/debit notes, and other transactional documents.

Before this advisory, HSN Table 12 GSTR-1 was filled manually, and Table 13 was optional. Now, validations and warnings ensure the required fields are completed correctly. GSTN clearly indicated that while the current system shows warnings, stricter controls may be implemented in the near future.

📈 Impact on Tax Professionals and Businesses

These changes improve data standardization and reconciliation, especially for matching ITC claims between suppliers and buyers. However, for tax professionals and filers, it increases the compliance burden, particularly for B2C-heavy entities and high-turnover businesses.

As per CBIC’s clarification via CBIC Post on X platform, B2B HSN reporting is mandatory while B2C remains optional for taxpayers with turnover under ₹5 crore. However, GSTN’s filing system now alerts users when B2C HSN is missing — potentially creating confusion and filing errors if not addressed properly.

🧠 Challenges for Filers for both HSN Table 12 GSTR-1 and Table 13

  • Incorrect or incomplete HSN entries may result in mismatch errors and GSTR-1 rejections.
  • Taxpayers must accurately distinguish B2B vs B2C transactions and match the respective HSN codes.
  • Omitting Table 13 even unintentionally may lead to warning messages or errors during submission.
