The Goods and Services Tax (GST) regime in India requires businesses to maintain transparency and accuracy in their tax filings. One of the key annual compliance requirements is GSTR-9C, often referred to as the GST audit and reconciliation statement.
What is GSTR-9C?
GSTR-9C is a reconciliation statement that compares the figures declared in your annual return (GSTR-9) with your audited financial statements. It is essentially a certification that the details filed in GST returns match the books of accounts.

This form is certified by either:
- A Chartered Accountant (CA), or
- A Cost Accountant.
Who Must File GSTR-9C for FY 2024-25?
As per the GST rules for FY 2024-25:
Every registered taxpayer with an aggregate turnover exceeding ₹5 crore during the financial year must file GSTR-9C.
In simple terms:
- If the turnover is above ₹5 crore, GSTR-9C is mandatory.
- If the turnover is up to ₹5 crore, you are exempt. You only need to file GSTR-9 (annual return), not GSTR-9C.
Format of GSTR 9C
Part-A: Reconciliation Statement
- Table 5 - Reconciliation of gross turnover
Map audited financials (entity or GST-registered segment) to "turnover under GST" after removing non-GST items/other branches, unbilled revenue, credit notes, etc.
- Table 6 - Reasons for differences in gross turnover (explain unreconciled items).
- Table 7 - Reconciliation of taxable turnover (from gross to taxable; exclusions such as exempt/zero-rated/RCM).
- Table 8 - Reasons for differences in taxable turnover.
- Table 9 - Reconciliation of tax liability & tax paid (rate-wise).
- Table 10 - Reasons for differences in tax payment.
- Table 11 - Additional liability payable (if any)-usually paid through DRC-03.
- Table 12 - Reconciliation of Net ITC.
- Table 13 - Reasons for differences in ITC.
- Table 14 - ITC as per expense-wise mapping (A-Q heads) vs ITC in GSTR-9 (e.g., purchases, freight, advertising, capital goods, etc.).
- Table 15 - Additional liability due to non-reconciliation (if any).
Verification (Self-certification)
- Registered person declares correctness & responsibility for differences; CA/CMA certification is not required for FY 2024-25.
Documents Needed
- Audited financial statements (entity & branch/unit breakup if applicable).
- GSTR-1 & GSTR-3B for all months of FY 2024-25; GSTR-9 draft/working.

- DRC-03 payment details if any extra liability arises.
Step-by-step: Filing GSTR-9C on the GST Portal
Prerequisites
- Ensure all monthly/quarterly returns (GSTR-1, 3B) are filed. Prepare and (preferably) finalise GSTR-9 first-9C pulls numbers from 9 and audited books.
- Login → Services ▸ Returns ▸ Annual Return → Select FY 2024-25 → Prepare Online for GSTR-9, complete and Submit (or keep saved) before moving to 9C.
- Open GSTR-9C (same Annual Return page): click Prepare Online (or Initiate Filing). The system will show Part-A tables.
Fill Part-A
- T5-T8 (Turnover): start with audited turnover, adjust per the on-screen guidance to reach GST turnover/taxable turnover; explain differences in T6 & T8.
- T9-T11 (Tax): enter rate-wise outward/RCM liability, tax paid; if any shortfall, create DRC-03 and record reference in T11.
- T12-T13 (ITC): reconcile Net ITC from books vs GSTR-9; give reasons for differences.
- T14 (Expense mapping): report eligible ITC against expense heads; the total should match ITC in GSTR-9 (net of reversals)
Compute liabilities (if any) → Pay via DRC-03 → capture CIN/ARN in the relevant fields.
Verification (self-declaration) → Proceed to File.
- Companies/LLPs: file with DSC.
- Others: EVC (OTP) allowed.
Download & keep the filed PDF/JSON and ARN for records. (It's often requested during scrutiny).
Due date to file GSTR 9C
The due date for filing GSTR-9C (reconciliation statement) is 31st December of the year following the relevant financial year, or such extended date as notified by the Government.
Penalty / late-fee for non filing or late filing
Late fee (for the complete annual return): Section 47(2) of the CGST Act levies a late fee for delay in furnishing the annual return under section 44. Practically this is ₹100/day under CGST + ₹100/day under SGST = ₹200/day total (until the cap), subject to the statutory maximum (quarter-percent cap under each Act - effectively 0.5% of turnover (state/UT) as the ceiling). CBIC clarified that late fee is levied until the complete annual return (GSTR-9 + GSTR-9C where applicable) is filed.
General penalty for non-filing (where no specific penalty exists): Since there's no separate penalty expressly for failing to furnish GSTR-9C, authorities may rely on Section 125 (general penalty) - maximum ₹25,000 - for contraventions where no other penalty is prescribed. Courts have sometimes limited application of Section 125 where a specific late fee is available, but the risk of notices/penalties (and subsequent litigation) exists.Show-cause / assessment risk and notices: non-filing can trigger departmental notices, GST assessments or audits - which can lead to demands, interest, and penalties depending on findings.
Important historical relief (time-bound): The Government (Notification 08/2025-Central Tax, 23-Jan-2025) and CBIC circular gave a limited waiver of excess late fees for pending GSTR-9C for FY 2017-18 to FY 2022-23 if filed on or before 31-Mar-2025 (no refund of fees already paid). That window has passed (current date is Oct 3, 2025), so that relief isn't available now - file asap to avoid present/ongoing late fees and penalties.
