Frequently Asked Questions (FAQs)
1. Is the GSTR-9 HSN summary mandatory for all taxpayers?
Table 17 is mandatory where HSN reporting applies. However, it may be skipped where nil liability is reported. The number of HSN digits depends on the taxpayer’s aggregate turnover in the preceding financial year.
2. What is the turnover-wise HSN requirement in GSTR-9?
Taxpayers with preceding-year turnover above ₹5 crore must report six-digit HSN codes. Taxpayers with preceding-year turnover up to ₹5 crore must report four-digit HSN codes for B2B outward supplies.
3. Are the HSN requirements in GSTR-9 and GSTR-1 the same?
The turnover-based HSN digit requirements broadly align, but the reporting formats differ. GSTR-1 reports periodic outward supplies through Table 12, whereas GSTR-9 provides the annual consolidated HSN summary in Table 17.
4. Is Table 18 mandatory in GSTR-9?
No. Table 18, which contains the HSN-wise summary of inward supplies, is optional for FY 2024-25. Check the applicable form instructions before using the same position for a later financial year.
5. What happens if I report the wrong HSN code?
An incorrect HSN code may create inconsistencies with GSTR-1, invoices and accounting records. It may also require an explanation during scrutiny because GSTR-9 cannot be revised after filing. A penalty is not automatic and depends on the nature of the contravention.
6. Where can I find the correct HSN code?
Use the HSN search facility available through the GST system and verify the code against the product description, chapter notes and applicable GST rate. For uncertain classifications, obtain advice from a qualified GST professional.
