GSTR-9: The GST Annual Return Explained
GSTR-9 is a once-a-year return that brings together everything a regular taxpayer reported in GSTR-1 and GSTR-3B during the financial year. It is the last chance to correct the year's picture, and it cannot be revised once filed.
Who must file
| Aggregate turnover in the year | GSTR-9 | GSTR-9C |
|---|---|---|
| Up to ₹2 crore | Exempt from 2024-25 onwards (optional for some earlier years) | No |
| Above ₹2 crore up to ₹5 crore | Yes | No |
| Above ₹5 crore | Yes | Yes, self-certified reconciliation statement |
Composition taxpayers file GSTR-4 instead. Casual taxable persons, non-residents, input service distributors and TDS/TCS filers do not file GSTR-9.
Due date
GSTR-9 is due by 31 December after the end of the financial year, so the return for 2025-26 is due on 31 December 2026. The late fee runs per day after that date; see our page on late fees and interest.
The same year has an earlier deadline that matters more: input credit for 2025-26 that you missed, and corrections to GSTR-1 and GSTR-3B for the year, must be made by 30 November 2026 or the date you file GSTR-9, whichever is earlier.
What is in it
| Part | Tables | Contents |
|---|---|---|
| I | 1–3 | Basic details |
| II | 4–5 | Outward supplies: taxable, exempt, nil-rated, non-GST, reverse charge |
| III | 6–8 | Input credit claimed, reversed and compared with GSTR-2B |
| IV | 9 | Tax payable and paid |
| V | 10–14 | Amendments for the year made in the next year's returns |
| VI | 15–19 | Demands and refunds, HSN summary of sales and purchases, late fee |
Worked example: finding a gap before filing
A hardware wholesaler in Hubballi with aggregate turnover of ₹3.2 crore in 2025-26 compares its GSTR-1 and GSTR-3B totals. GSTR-1 shows taxable outward supplies of ₹3,20,00,000; the twelve GSTR-3Bs add up to ₹3,18,50,000. The ₹1,50,000 difference is one March invoice that went into GSTR-1 but was left out of March's GSTR-3B.
Tax on it at 18% is ₹27,000. GSTR-9 cannot be used to pay tax, so the wholesaler pays ₹27,000 with interest through DRC-03 and shows it in table 9. In table 8, GSTR-2B shows input credit of ₹40,10,000 against ₹40,00,000 claimed; the ₹10,000 difference is a bill the supplier reported late, which can only be claimed up to the 30 November cut-off.
Common mistakes
- Treating GSTR-9 as a place to pay extra tax; it is a statement, and tax goes through DRC-03
- Filing before reconciling GSTR-1, GSTR-3B, GSTR-2B and the books
- Missing the 30 November cut-off for claiming the year's pending credit
- Copying auto-filled figures without checking them
- Forgetting that the return cannot be revised after filing
How it connects to your books
GSTR-9 should agree with your accounts: sales in the profit and loss statement, adjusted for credit notes, advances and non-GST income, should explain table 4; GST input credit in the ledger should explain table 6. Where turnover is above ₹5 crore, GSTR-9C sets out that reconciliation formally. A chartered accountant should review both before filing.
Checklist before you file
- GSTR-1 and GSTR-3B totals for all 12 months agree, or each difference is explained
- Tax short-paid has been paid through DRC-03 with interest
- Input credit claimed agrees with GSTR-2B and the books; ineligible credit is reversed
- Credit notes and amendments made after March are shown in Part V
- HSN summary of outward supplies is complete
- Late fees for any late monthly returns have been paid
- A chartered accountant has reviewed the draft
How TripleBill helps
TripleBill keeps GSTR-1 and GSTR-3B figures for every month from the same books, exports them to Excel, and reconciles GSTR-2B against your bills (Starter and Pro), which is most of the work behind GSTR-9. Filing is done on gst.gov.in.

Frequently asked questions
Is GSTR-9 mandatory for small businesses?
Not for regular taxpayers with aggregate turnover up to ₹2 crore, from 2024-25 onwards. Above ₹2 crore it is mandatory.
What is the due date for GSTR-9?
31 December after the financial year, unless extended by notification.
What is GSTR-9C?
A reconciliation statement between the annual return and the audited financial statements, self-certified by the taxpayer, required when turnover exceeds ₹5 crore.
Can I revise GSTR-9?
No. Once filed it cannot be revised, which is why reconciliation before filing matters.
Can I claim missed ITC in GSTR-9?
No. GSTR-9 only reports. Missed credit for a year must be claimed in a GSTR-3B filed by 30 November of the next year.
Do composition dealers file GSTR-9?
No, they file GSTR-4.
What happens if my GSTR-9 shows a difference from GSTR-3B?
Pay any tax short-paid through DRC-03 with interest before filing, and expect the officer to ask about unexplained differences during scrutiny. Differences in your favour cannot be claimed through GSTR-9.
