If your PAN-India turnover exceeded ₹5 crore in FY 2024-25, GSTR-9C is your mandatory self-certified reconciliation statement, bridging GSTR-9 data with audited financials to flag mismatches in turnover, tax, and ITC. With recent updates like new ITC tables and late fee tracking, it’s more critical than ever to avoid notices.
This guide covers GSTR-9C applicability for FY 2024-25, the turnover threshold, due date, late fees, key changes, and a complete documentation checklist. We’ve also added an ITC flowchart, GSTR-9 vs. GSTR-9C comparison, and a filing timeline to streamline your process.
What is GSTR-9C (FY 2024-25)
GSTR-9C, under Section 35(5) read with CGST Rule 80(3) reconciles:
- GSTR-9 (annual return) disclosures
- Audited financial statements (P&L, Balance Sheet, Form 3CD)
It’s self-certified by the taxpayer, no mandatory CA/CMA audit (unless state-specific rules apply). But with Central Tax Notification No. 13/2025 (September 17, 2025), expect granular ITC tracking and a new late fee table to enhance transparency and reduce litigation.
Key Changes in GSTR-9C for FY 2024-25
Major updates focus on ITC precision and cross-year adjustments (aligned with GSTR-9 changes):
| Change | Description | Impact on GSTR-9C |
| New Table 12B/12C | ITC as per books vs. reconciled with GSTR-9 Table 13 (cross-year availed ITC) | Mandatory; flags book-return mismatches |
| Table 6A1 Linkage | Prior-year ITC (FY 2023-24) claimed in current FY (excludes Rule 37/37A reclaims) | Reconciled in Part IV; use for non-reversal claims |
| ITC Reclaim under Rule 37/37A | Treated as ITC of reclaim year (e.g., FY 2025-26), reported in GSTR-9 Table 6H | Part IV reconciliation; avoids double-counting in prior-year tables |
| New Table 17 (Late Fee) | Payable and paid late fees (per Circular No. 246/03/2025-GST) | Auto-calculated; reconciles with Part III tax payments |
| Table 7D1 | E-commerce supplies (TCS) reversals | Integrated in Part IV for better outward supply alignment |
Pro Tip: Reconciliations now pull from updated GSTR-9 tables, prepare after December 1, 2025, for full auto-population.
GSTR-9 vs. GSTR-9C: Quick Comparison
| Aspect | GSTR-9 | GSTR-9C |
| Applicability | > ₹2 crore (mandatory); ≤ ₹2 crore exempt/optional | > ₹5 crore (mandatory, self-certified) |
| Purpose | Consolidate supplies, ITC, tax from monthly returns | Reconcile GSTR-9 with audited books |
| Key Tables | 4–5 (outward), 6–8 (ITC), 9 (tax payable) | Parts I–V: Turnover, tax, ITC, expenses, liability |
| Certification | Self | Self (no CA unless state-mandated) |
| Due Date | Dec 31, 2025 | Same, but post-GSTR-9 filing |
Who Must File GSTR-9C for FY 2024-25?
| Aggregate Turnover (PAN-India, incl. exempt/ export/ nil-rated) | Required? | Notes |
| > ₹5 crore | Yes (Mandatory) | Self-certified; reconciles full FY |
| ≤ ₹5 crore | No | Exempt, even if GSTR-9 mandatory |
| Composition/ ISD/ Casual/ NRTP | No | Separate forms (e.g., GSTR-9A) |
Legal Basis: Threshold per Notification No. 30/2021-Central Tax; turnover per Section 2(6) CGST Act.
Due Date & Late Fee for GSTR-9C (FY 2024-25)
- Due Date: 31st December 2025 (post-GSTR-9 filing; no extension yet).
- Late Fee: ₹200/day (₹100 CGST + ₹100 SGST), capped at 0.50% of turnover (0.25% per Act).
- Key Update: Separate calculation for GSTR-9C, from the later of GSTR-9 filing/original due date to GSTR-9C filing date.
- Example: GSTR-9 filed Jan 5, 2026; GSTR-9C Jan 7 → 7 days fee (5 for GSTR-9 + 2 for GSTR-9C).
GSTR-9C Self-Certification FY 2024-25: ITC Reconciliation Flowchart
Follow this sequence for Part IV (ITC) to handle Rule 37/37A correctly:
- Claim ITC (Table 12A): Total per books (current + prior year).
- Reverse if Ineligible (Link to GSTR-9 Table 7): Rule 37 (non-payment) or 37A (supplier non-filing), temporary reversals.
- Reconcile with Returns (Table 12B): Match GSTR-9 Tables 6–8 + GSTR-2B; explain variances.
- Reclaim (Table 12C): Post-reversal reclaims treated as current-year ITC (e.g., in GSTR-9 Table 6H).
- Cross-Year Adjustments: Report in GSTR-9 Tables 12/13; reconcile here if availed/reversed next FY.
Visual Note: Linear flow: Books ITC → Reversals (Rule-specific) → GSTR-9 Match → Reclaim as Current → Cross-Year Flag. Use Excel for variance tracking.

- Rule 37/37A reclaims in wrong table (use 6H, not 6A1).
GSTR-9C Self-Certification FY 2024-25: Quick FAQs
Is CA certification required for GSTR-9C in FY 2024-25?
No, self-certification by authorized signatory suffices (since FY 2020-21; state exceptions rare).
What if GSTR-9C is filed after GSTR-9?
Allowed, but late fee accrues separately from the later of GSTR-9 filing or Dec 31 to GSTR-9C date.
Filing Timeline: Start Early to Avoid Rush
| Month/Period | Action |
| November 2025 | Start reconciliations (books vs. returns); build Excel workings. |
| December 1–25, 2025 | Finalize draft GSTR-9C; verify new tables (12B/17). |
| December 26–31, 2025 | File GSTR-9 then GSTR-9C; self-certify and submit. |
Final Thoughts
GSTR-9C self-certification FY 2024-25 demands precise ITC handling under Rule 37/37A and cross-year tracking, but early prep saves audits. Use the timeline above for a notice-free close. Happy compliant filing!
