GSTR-9
GST annual return
GSTR-9 is the annual GST return. It brings together a regular taxpayer's sales, purchases, input tax credit and tax paid for the whole financial year, as reported in GSTR-1 and GSTR-3B, and is due by 31 December after the year ends. It is optional if your turnover is up to ₹2 crore.
Why it matters to your business
GSTR-9 is your last look at the year. It is where sales you missed, credit you claimed twice or never claimed, and tax you still owe come to light. It cannot be revised after filing, and 30 November and the annual return are also the cut-off for claiming the year’s input tax credit and for credit notes, so the work before filing matters more than the form itself.
How it works
As of October 2026:
- It has tables for outward supplies, input tax credit claimed and reversed, tax paid, changes made after the year, and an HSN summary of sales and purchases.
- Most figures are drawn by the portal from your GSTR-1 and GSTR-3B, with your credit compared against the year’s GSTR-2B. You confirm or correct them against your books.
- Extra tax found while preparing it is paid through form DRC-03. Extra credit cannot be claimed through GSTR-9.
- It is filed for each GSTIN separately.
- A late fee is charged for each day of delay, with lower rates for smaller turnovers.
An example
A Nagpur distributor with a turnover of ₹8 crore prepares GSTR-9 for 2025-26. Its books show sales of ₹8.02 crore, but GSTR-1 for the year adds up to ₹7.98 crore: one invoice of ₹4 lakh was never reported. The distributor reports it and pays the tax with interest through DRC-03, then files GSTR-9 and GSTR-9C before 31 December 2026.
Common mistakes
- Filing straight from the portal’s figures without comparing them with the books.
- Leaving reconciliation until the last week of December.
- Trying to claim missed credit in GSTR-9.
- Forgetting the HSN summary of purchases.
Questions about GSTR-9
Who must file GSTR-9?
Every regular GST-registered business with a turnover of more than ₹2 crore in the financial year. Below that it is optional. Composition dealers file GSTR-4 instead, and casual and non-resident taxpayers are not covered.
What is the due date of GSTR-9?
31 December after the end of the financial year. For 2025-26 that is 31 December 2026, unless the government extends it.
What is GSTR-9C?
A reconciliation statement between your annual return and your audited accounts. It is filed with GSTR-9, self-certified, when your turnover is more than ₹5 crore.
Can GSTR-9 be revised?
No. Once filed it cannot be changed, so reconcile your books with GSTR-1, GSTR-3B and GSTR-2B before you file.
