The following 10 reconciliations are non-negotiable and must be completed, documented, and signed-off before the filing deadline.
| SL No | Name of the reconciliation | What to reconcile | Ideal outcome | Root cause for difference |
| 1. | Annual turnover | Audited Financial Statements (AFS) vs. GSTR-9 (Table 5A) | Zero difference | Variance greater than ₹5 Lakh. |
| 2. | Outward tax liability | Books liability vs. GSTR-3B tax paid | Liability = Tax paid | Unaccounted payments or short payment interest risk. |
| 3. | Outward supplies | GSTR-1 turnover vs. GSTR-3B turnover | Equal match | Invoices filed but liability under-reported. |
| 4. | Rate-wise tax | Separate calculations for 5%, 12%, 18%, 28% supplies | Balanced by rate | Missed Reverse Charge Mechanism (RCM) or misclassified supplies. |
| 5. | HSN-wise summary | GSTR-9 (Table 5N) vs. GSTR-9 (Table 17) | Equal match | Mismatch in HSN codes, leading to audit query on classification. |
| 6. | Inward ITC claimed | Books vs. GSTR-3B ITC claimed | Equal match | Excess or missed ITC in monthly returns. |
| 7. | ITC eligibility (GSTR-2B) | Eligible books ITC vs. GSTR-2B ITC | Full match for eligible ITC | Discrepancy means vendor non-filing (Rule 37A risk) or blocked credit claim. |
| 8. | ITC segregation | Prior FY ITC vs. current FY ITC (via Table 6A1) | Full disclosure | Large unexplained difference in the prior FY ITC category. |
| 9. | Closing balances | GST cash ledger + ITC ledger in books vs. GST portal | Exact reconciliation | Portal sync issues or unreconciled Electronic Credit/Cash Ledger (ECL). |
| 10. | Spillover & amendments | FY 23-24 claims/adjustments reported in GSTR-3B of FY 24-25 | Correctly tagged | Double-counting in GSTR-9 Table 4/5 or late amendments after 30th Nov deadline. |
The timeline for annual compliance is fast approaching. CFOs must ensure the team operates on a strict schedule, focusing efforts around the Section 16(4) and Section 37/39 deadline of 30th November.
| Deadline | Critical action steps | Risk mitigation focus |
| By 30th November 2025 (Absolute cut-off) | Claim all missed ITC for FY 24-25 via GSTR-3B (or forfeit it forever). Complete all GSTR-1 & GSTR-3B amendments. Document all Rule 37/37A ITC reversals with reasons. Segregate prior-year ITC (prepare data for the new Table 6A1). | ITC loss & penalty avoidance |
| By 1st December 2025 | Download the final GSTR-2B statement to verify Table 8A auto-population (which excludes prior-year invoices). | Data integrity check |
| By 20th December 2025 | Complete the 10 critical reconciliations (turnover, ITC, HSN, tax rate). Resolve all Table 6J, 8D, and 9 mismatches. Prepare Form DRC-03 for any additional tax liability identified. | Pre-audit readiness |
| By 31st December 2025 (Due date) | File GSTR-9. File GSTR-9C (mandatory if turnover > ₹5 Cr). Pay any additional tax via DRC-03 (if any). | Compliance closure |
