Introduction (What Is HSN Summary in GSTR-9?)

Every registered taxpayer filing GSTR-9 must provide a consolidated summary of all goods and services supplied or received—classified by their HSN (Harmonised System of Nomenclature) codes.
This section helps the GST Department understand the nature of supplies, tax liability distribution, and overall business activity.

From FY 2021-22 onward, the HSN Summary is mandatory, and the taxpayer must report outward and inward supplies separately based on applicable turnover slabs.

In this article, you’ll learn:
✔ What the HSN Summary includes
✔ Turnover-based reporting requirements
✔ How values must be filled
✔ Common mistakes to avoid
✔ How TallyPrime automatically prepares HSN data for easy GSTR-9 filing

1. Why HSN Summary Is Required in GSTR-9

The GST Council mandates HSN-wise reporting for:

• Improving tax classification accuracy
• Standardizing supply reporting across industries
• Tracking product-wise tax contribution
• Preventing misclassification and tax evasion

The HSN Summary provides the government with a national-level dataset of what goods/services are being supplied, in which quantities, and at what tax rates.

2. HSN Summary Sections in GSTR-9

There are two major tables inside the Annual Return:

A. Table 17 – HSN-Wise Summary of Outward Supplies

Here, you must report:

• HSN code
• Description of goods/services
• UQC (Unit Quantity Code)
• Total quantity
• Total value
• Taxable value
• Integrated / Central / State / Cess tax amounts

B. Table 18 – HSN-Wise Summary of Inward Supplies

Here, you report inward supplies where:

• Total inward supply value per HSN exceeds 10% of total purchases, or
• The value exceeds limits notified by GST law

Most businesses report inward supplies on a best-estimate basis based on their purchase registers.

3. Turnover-Based Requirements for HSN Summary

The HSN Summary requirement depends on your aggregate turnover:

For services, Service Accounting Codes (SAC) apply.

4. What Data Must Be Filled in the HSN Summary?

You must summarize all outward and inward supplies under each HSN.

For every HSN, report:

• ✔ HSN Code
• ✔ Description
• ✔ UQC (KG, NOS, LTR, etc.)
• ✔ Total Quantity
• ✔ Total Value of Supplies
• ✔ Taxable Value
• ✔ IGST/CGST/SGST/Cess amounts

Important Note:

The values you fill in GSTR-9 should match (or reasonably align with) Books of Accounts, not necessarily GSTR-1 or GSTR-3B.

5. Common Mistakes Taxpayers Make

❌ Using incorrect HSN code

❌ Reporting 2-digit HSN instead of 4/6 digits

❌ Not mentioning UQC correctly

❌ Mismatch between taxable value and total value

❌ Wrongly mapping purchase and sales HSNs

❌ Missing inward supplies above threshold

These errors often cause return mismatches during audits.
