GSTR-9C — GST Audit Reconciliation Statement Guide for India

GSTR-9C is the GST Reconciliation Statement — filed alongside the Annual Return (GSTR-9). It reconciles the figures reported in the annual GST returns with the audited financial statements. For businesses with turnover above the prescribed limit, GSTR-9C is mandatory and must be certified by a Chartered Accountant. Here is the complete guide.

Who Must File GSTR-9C?

GSTR-9C is required for registered taxpayers whose aggregate annual turnover exceeds ₹5 crore in the relevant financial year. Below ₹5 crore, GSTR-9C is optional (self-certification without CA required). Note: Previously, the threshold was ₹2 crore and required mandatory CA certification — this was relaxed to ₹5 crore (self-certifiable) from FY 2020-21 onwards.

What Does GSTR-9C Reconcile?

GSTR-9C reconciles the figures reported in GSTR-9 (the annual return based on GST system data) against the annual audited financial statements. Key reconciliations include:

• Turnover reconciliation: Gross turnover as per financial statements vs turnover reported in GSTR-9 — explaining differences (inter-state supplies, advances, debit/credit notes, etc.)
• Tax paid reconciliation: GST paid as per GSTR-9 vs tax paid per financial statements
• ITC reconciliation: ITC claimed in GSTR-9 vs ITC as per financial books — unexplained differences must be paid with interest
• Reason for unreported/under-reported supply: Any discrepancy in sales figures must be explained

Self-Certification vs CA Certification

From FY 2020-21, taxpayers with turnover below ₹5 crore can self-certify GSTR-9C — the taxpayer themselves submits the reconciliation statement without requiring a CA to certify it. For turnover above ₹5 crore, the reconciliation must still be prepared and submitted — though the requirement of mandatory CA audit sign-off has been relaxed. However, given the complexity and the consequences of errors, engaging a CA is strongly advisable even for those below ₹5 crore.

Due Date for GSTR-9C

GSTR-9C must be filed by the same due date as GSTR-9 — currently 31 December of the year following the financial year (e.g., 31 December 2026 for FY 2025-26). Late filing of GSTR-9C attracts a late fee under Section 47 and possible interest on any additional tax liability identified through reconciliation.

Consequences of GSTR-9C Mismatch

If the GSTR-9C reconciliation reveals that sales were under-reported or ITC was over-claimed in GSTR-9, the difference must be paid as additional tax in the annual return along with interest at 18% per annum from the due date of the relevant monthly return. Significant unexplained discrepancies can trigger GST audit or investigation under Section 65 or 66.
