GSTR-9 Annual Return Filing — Complete Guide for 2026
By Parul Singh, GST Practitioner · GST Returns
Table of Contents
I file 100+ GSTR-9 annual returns every year. Most Delhi businesses treat it as a formality, but mismatches between GSTR-1 and GSTR-3B data show up here and trigger scrutiny.
GSTR-9 is the annual return under GST that consolidates all the monthly/quarterly returns filed during the financial year. It helps in reconciling the data reported throughout the year.
Who Must File GSTR-9
All regular taxpayers with turnover above ₹2 crore must file GSTR-9. Taxpayers under the composition scheme file GSTR-9A. The due date is typically 31 December of the following financial year.
Key Tables in GSTR-9

Common Reconciliation Issues
- GSTR-1 turnover ≠ GSTR-3B turnover
- ITC claimed in GSTR-3B ≠ ITC available in GSTR-2A
- Exempt supply declarations inconsistent across returns
- Missing credit/debit notes
