GSTR-9 vs GSTR-9C: Who Files Which

Two different filings, often confused

GSTR-9 and GSTR-9C are both annual GST filings, but they serve different purposes and apply to different businesses depending on turnover.

GSTR-9: The Annual Return

GSTR-9 consolidates the year's monthly/quarterly return data into a single annual filing — a summary of outward and inward supplies, tax paid, and ITC claimed across the year. Most regular registered taxpayers above the applicable turnover threshold are required to file it; certain categories (like composition taxpayers, who file a separate simplified annual return) are excluded.

GSTR-9C: The Reconciliation Statement

GSTR-9C goes a step further — it reconciles the figures reported in GSTR-9 against the taxpayer's audited financial statements, and is required only above a higher turnover threshold than GSTR-9 itself. It highlights and explains any differences between the GST returns and the books of account.

Why the reconciliation matters

GSTR-9C isn't a formality — it's where mismatches between "what GST returns say" and "what the audited books say" get surfaced and explained. A business with clean, well-reconciled records throughout the year usually finds this a straightforward exercise; one that hasn't reconciled regularly often discovers discrepancies here that need real investigation.

A practical note on thresholds

Both the GSTR-9 and GSTR-9C applicability thresholds are turnover-based and have been revised over time, so it's worth confirming the current thresholds for your business rather than relying on what applied in a prior year.
