GST Annual Return Data Pack for SMEs

Finin2min GST Desk·June 2026·7 min readReviewed 20 June 2026GSTR-9

GST annual return preparation should not begin on the portal. It should begin with a year-wise data pack that reconciles books, returns, ITC, RCM, refunds and notices.

Quick answer: GSTR-9 is mandatory once aggregate turnover for the year exceeds ₹2 crore; GSTR-9C (the reconciliation statement) kicks in above ₹5 crore and has been self-certified by the taxpayer, not CA/CMA-certified, since FY 2020-21. Both are due by 31 December following the financial year, and a late GSTR-9 attracts ₹200/day (₹100 CGST + ₹100 SGST) capped at 0.25% of turnover.

For broader context, see the GST Law & Practice Hub.

Who actually has to file, and when

Turnover (FY)	GSTR-9	GSTR-9C
Up to ₹2 crore	Optional	Not applicable
Above ₹2 crore up to ₹5 crore	Mandatory	Not applicable
Above ₹5 crore	Mandatory	Mandatory (self-certified, no CA/CMA sign-off required since FY 2020-21)

Both forms are due by 31 December following the end of the financial year, unless a notification extends the date. Missing GSTR-9 attracts a late fee of ₹200/day (₹100 CGST + ₹100 SGST), capped at 0.25% of turnover in that state/UT — confirm the current cap and rate against the latest notification before relying on this figure for a specific filing.

Worked example

An SME with ₹3 crore annual turnover must file GSTR-9 but NOT GSTR-9C (under the ₹5 crore threshold). A second SME with ₹6 crore turnover must file both GSTR-9 AND a self-certified GSTR-9C reconciling its books to the returns filed — the extra reconciliation burden exists specifically because it crossed the ₹5 crore line, not because of any other factor.
