GSTR-9
Also known as: annual GST return, GST annual return
GSTR-9 is the annual GST return that consolidates a financial year's monthly and quarterly filings. It is due by 31 December following the year and is mandatory for taxpayers with turnover above ₹2 crore. Above ₹5 crore, a GSTR-9C reconciliation statement is also required.
GSTR-9 is the annual GST return that pulls a taxpayer’s full year of activity into one consolidated filing. It reconciles outward and inward supplies, tax paid and input tax credit claimed across every monthly or quarterly return filed during the financial year.
Thresholds, due date and GSTR-9C
The key thresholds and dates:
- Due date: 31 December following the end of the financial year
- Mandatory for taxpayers with aggregate turnover above ₹2 crore
- GSTR-9C — a reconciliation statement — is additionally required where turnover exceeds ₹5 crore
(Always confirm near the deadline — government extensions are common.)
GSTR-9 is a reconciliation exercise, not fresh data entry. It draws on the year’s GSTR-1 and GSTR-3B filings, so the accuracy of the annual return depends entirely on how clean those monthly returns were. Mismatches between books, GSTR-1 and GSTR-3B surface here and have to be explained or corrected.
For CA firms, the annual return is a year-end push that rewards clean books kept through the year. Where the monthly cycle was tracked properly on a compliance calendar, GSTR-9 goes far more smoothly.
