GSTR-9C FY25: Table 12B Redundant and Table 12F Mismatch

The Silent Trap in GSTR-9C FY 2024-25: When Table 12B Becomes Redundant and Table 12F Explodes — The Cross-Year ITC Reporting Paradox 

Summary

GSTR-9C for FY 2024-25 has introduced a structural paradox that threatens to generate unexplained reconciliation differences for thousands of taxpayers: the insertion of new Table 6A1 in GSTR-9 — which captures prior-year (FY 2023-24) ITC claimed in FY 2024-25 — has rendered Table 12B of GSTR-9C functionally redundant while simultaneously causing Table 12F (unreconciled ITC differences) to produce inflated figures that do not reflect any genuine non-compliance. This article analyses the three distinct scenarios in which this paradox manifests, examines the legal risk arising from unexplained Table 12F balances under Sections 73 and 74 of the CGST Act, 2017, and explains the accounting methodology conflict that lies at the heart of this trap.

Introduction:-

GSTR-9C, the reconciliation statement under Section 35(5) read with Rule 80(3) of the CGST Rules, 2017, serves as the bridge between a registered person’s audited books of accounts and the data filed in GSTR-9. Part IV of GSTR-9C (Tables 12A to 12F) is specifically designed to reconcile ITC as per the taxpayer’s books of accounts with ITC as reported in GSTR-9. The reconciliation flows as follows: Table 12A captures ITC as per audited financial statements; Table 12E is auto-populated from Table 7J of GSTR-9 (net ITC availed as per annual return); and Table 12F represents the unreconciled difference between the two. Any positive balance in Table 12F is a red flag that typically signals under-claimed ITC or a dispute between the taxpayer’s books and the return data.

With effect from FY 2024-25, Notification No. 13/2025-CT dated 17th September 2025 introduced a fundamental structural change to GSTR-9: the insertion of Table 6A1, which specifically captures ITC pertaining to the preceding financial year (FY 2023-24) that was claimed in FY 2024-25 through GSTR-3B. Table 6A1 was designed to improve the year-wise segregation of ITC and align GSTR-9 disclosure with the static GSTR-2B framework. What was not anticipated in the design of GSTR-9C — which was not correspondingly amended — is that this laudable change creates a three-way structural collision in Tables 12A, 12B, 12E, and 12F that produces artificial reconciliation differences with real legal consequences.

The Structural Architecture: What Tables 12A–12F Were Designed to Do

To understand the paradox, it is necessary to first understand the intended flow of Tables 12A–12F in the reconciliation statement:

(i) Table 12A: ITC as per the audited accounts of the registered person for the financial year — i.e., ITC recorded in the books (both for the current year and, in many cases, for prior years if the entity follows accrual-based accounting).

(ii) Table 12B: ITC booked in the financial statements of an earlier year but claimed (availed) in the current financial year — intended as a deduction from the reconciliation to explain why Table 12A may be higher than GSTR-9 data.

(iii) Table 12C: ITC booked in the financial statements for the current year but claimed in a subsequent financial year — another reconciling item.

(iv) Table 12E: Auto-populated from Table 7J of GSTR-9 — net ITC availed for the financial year as per the annual return.

(v) Table 12F: The arithmetic residual — 12A minus 12B minus 12C minus 12E — representing ITC in the books that is neither explained by cross-year timing differences nor matched to the annual return. A non-zero Table 12F is meant to flag unexplained discrepancies requiring explanation in Table 13.

Under the pre-FY 2024-25 framework, this architecture worked coherently: Table 7J of GSTR-9 included all ITC claimed in the year through GSTR-3B — including prior-year ITC claimed in the current year. Table 12B therefore performed a useful reconciling function, and Table 12F reflected only genuine unexplained differences.

The Cross-Year ITC Reporting Paradox: How Table 7J’s Exclusion Breaks the Reconciliation

The structural rupture arises from one critical design decision in the FY 2024-25 amendments: Table 7J of GSTR-9 now reflects net ITC pertaining exclusively to FY 2024-25. ITC of FY 2023-24 claimed in FY 2024-25, which was previously included in the GSTR-3B summary flowing into Table 7J, is now segregated into Table 6A1 and is specifically excluded from Table 7J.

This means: Table 12E (auto-populated from Table 7J) is now a current-year-only figure. Table 12B, by contrast, still asks for ITC booked in earlier financial years and claimed in the current year. But since Table 7J does not include the prior-year ITC any more (it has been moved to Table 6A1), the very ITC that Table 12B is intended to explain is no longer part of Table 12E’s denominator. Table 12B now purports to explain a figure that is not in Table 12E — making it functionally redundant while simultaneously generating an artificial inflated difference in Table 12F.

The GSTN’s Additional FAQ dated 4th December 2025 formally acknowledges this anomaly, stating that ‘Table 12B of GSTR-9C for FY 2024-25 becomes redundant as Table 7J of GSTR-9 of FY 2024-25 does not consider the ITC of FY 2023-24 claimed or reversed in FY 2024-25.’ However, the FAQ does not resolve the underlying design flaw — it merely advises taxpayers to explain any resulting difference in Table 12F through Table 13 of GSTR-9C.

Three Scenarios Where the Paradox Manifests

Scenario 1: Accrual-Based Accounting — ITC Booked in FY 2023-24, Claimed in GSTR-3B of FY 2024-25

A manufacturer received an invoice dated 28th March 2024 from a supplier. The supplier filed GSTR-1 late and the invoice appeared in the recipient’s GSTR-2B only in May 2024. The manufacturer’s accountant, following Ind AS 2/AS 2 on accrual accounting, recorded the ITC in the books of FY 2023-24. The ITC was claimed in GSTR-3B of May 2024 (FY 2024-25).

Under the new framework: The ITC appears in Table 6A1 of GSTR-9 for FY 2024-25 (preceding-year ITC claimed in current year). It is excluded from Table 7J. Table 12A of GSTR-9C for FY 2024-25 does not include this ITC (since it was booked in FY 2023-24 books). Table 12E (from Table 7J) is also lower by this amount. So far, no reconciliation problem. However, if the same entity also booked some other FY 2023-24 ITC in FY 2024-25 books (e.g., due to a different accounting methodology for certain supplies), Table 12A will be higher than Table 12E by the amount of such cross-year ITC — and Table 12B will not help because it is not adjusting Table 12E’s denominator.

Scenario 2: Current-Year ITC Booked in FY 2024-25 Books But Table 7J is Lower — The False Table 12F

A service company’s audited financial statements for FY 2024-25 include ITC on invoices that were received and booked in the year but whose suppliers filed GSTR-1 late — the invoices appeared in GSTR-2B only in April–October 2025. The ITC was claimed in GSTR-3B of April–June 2025 (FY 2025-26). In the GSTR-9C for FY 2024-25: Table 12A includes this ITC (it is in FY 2024-25 books). Table 12C should capture it (ITC booked in current year, claimed in subsequent year). Table 12E (Table 7J) does not include it (claimed in FY 2025-26). Result: If Table 12C is correctly populated, Table 12F should be nil. However, taxpayers frequently misclassify this as Table 12B rather than Table 12C — because the ITC was claimed in the ‘next’ financial year — inflating Table 12F with a figure that represents compliant behaviour.

Scenario 3: The Double-Adjustment Trap — When Prior-Year ITC is in Both Table 6A1 and GSTR-9C

This is the most dangerous scenario. A trading company with a large volume of cross-year transactions has ₹45 lakh of FY 2023-24 ITC claimed in FY 2024-25 GSTR-3B. The GSTR-9C preparer correctly reports this in Table 12B. However, since Table 7J (which feeds Table 12E) already excludes this ₹45 lakh (it is in Table 6A1 of GSTR-9), Table 12B’s deduction from Table 12A creates a net under-deduction of ₹45 lakh in Table 12F — because Table 12F = 12A − 12B − 12C − 12E, and both 12B and 12E have already ‘removed’ this ₹45 lakh from different directions. The taxpayer has effectively double-counted the exclusion, leaving Table 12F with a large unexplained negative balance.

Legal Risk: When Table 12F Becomes a Notice-Trigger

The legal significance of Table 12F must not be understated. Under the GST audit and scrutiny framework, GSTR-9C is one of the primary data points used by the Department to identify potentially under-paid tax and under-claimed reversals. An unexplained positive balance in Table 12F — representing ITC in the taxpayer’s books that has not been claimed in GSTR-9 — can be construed by the Department as evidence of: (a) excess ITC availed in the books but not reversed; or (b) under-declaration of taxable turnover. Either interpretation can trigger proceedings under Section 61 (scrutiny of returns), Section 65 (GST audit), or, in cases of alleged fraud, Section 74 of the CGST Act, 2017.

The GSTN FAQ’s advice to ‘explain the reason in Table 13 of GSTR-9C’ is procedurally sound but legally insufficient. Table 13 is a free-text field — it has no binding legal status and does not constitute a statutory clarification or admission. A taxpayer who reports ₹50 lakh in Table 12F and writes ‘cross-year ITC timing difference per Table 6A1 — refer GSTN FAQ dated 04-12-2025’ in Table 13 is, in the current framework, relying on non-binding CBIC administrative guidance to protect against a potentially adversarial assessment. This is a fragile compliance position that the CBIC should remedy through a formal Circular.

The Accounting Methodology Conflict: Ind AS vs. GST Reporting Year

A deeper structural issue underlies this paradox: the conflict between Indian accounting standards (Ind AS / AS under Companies Act, 2013) and the GST law’s concept of ‘financial year’ for ITC reporting. Under Ind AS 2 / AS 2 and the accrual principle, ITC is recognised in the financial statements of the year to which the supply pertains — i.e., FY 2023-24 for invoices dated in FY 2023-24, regardless of when the GSTR-2B entry appears. Under GST law, as clarified by the GSTN FAQ, ITC is ‘of the year in which it is claimed in GSTR-3B’ for the purposes of Table 6A1 and GSTR-9 reporting.

This divergence means that for any taxpayer following Ind AS, Table 12A of GSTR-9C (which is based on audited financial statements) will always reflect ITC on an accrual basis, while Table 12E (from Table 7J) reflects ITC on a claimed/paid basis. The only mechanism to bridge this gap — Table 12B — is now functionally neutralised for FY 2024-25, as explained above. The GSTN FAQ acknowledges this by stating that the value in Tables 12A to 12C ‘may be reported as per the accounting methodology adopted by the taxpayer’ — but this flexibility, while welcome, does not resolve the structural mismatch in Table 12F.

Summary of the Paradox — Scenario-wise Impact

What CBIC Has Said — and What It Has Not

The GSTN’s consolidated FAQ dated 17th December 2025 and additional FAQ dated 4th December 2025 provide the following official position on Table 12B and Table 12F:

– Table 12B of GSTR-9C ‘continues to be relevant’ — but the ITC values captured therein ‘will not appear in Table 12A (ITC as per books) or 12E (ITC as per GSTR-9)’ when the prior-year ITC was booked in the earlier year’s books but claimed in the current year’s GSTR-3B.

– The values in Tables 12A to 12C ‘may be reported as per the accounting methodology adopted by the taxpayer.’

– Any ‘differences in Table 12F of GSTR-9C, taxpayer may provide the reason for un-reconciled differences in ITC in Table 13 of GSTR 9C.’

What the FAQs do not address is: (i) the legal effect of a Table 12F balance supported only by Table 13 free-text explanation in the context of a Section 73/74 notice; (ii) whether a formal Circular will be issued to provide statutory shelter to taxpayers affected by this structural anomaly; (iii) the position of taxpayers under departmental audit where the auditors may not accept Table 13 explanations as conclusive; and (iv) whether GSTR-9C will be prospectively amended to introduce a dedicated row for ‘ITC of preceding FY reported in Table 6A1 of GSTR-9’ as a reconciling item in Part IV.

The absence of a formal CBIC Circular on this point — relying instead on non-binding administrative FAQs — leaves taxpayers in a legally precarious position, particularly larger enterprises with multi-crore cross-year ITC adjustments.

Key Takeaways for Practitioners

First, Table 12B is not entirely irrelevant — but its utility has been fundamentally altered. For taxpayers whose prior-year ITC is booked in prior-year accounts and claimed in FY 2024-25 (via GSTR-3B), Table 12B performs no reconciling function in the GSTR-9C framework for this year. Practitioners should identify the accounting treatment of each cross-year ITC item before populating Table 12B.

Second, the distinction between Table 12B and Table 12C is critical. Table 12B is for ITC booked in earlier financial year accounts but claimed in the current year. Table 12C is for ITC booked in current year accounts but claimed in the subsequent year. Mis-classification between these two tables directly inflates Table 12F and creates audit risk. Every cross-year ITC item must be traced to the year it was booked in the audited accounts — not the year of claim.

Third, Table 12F balances must be documented, not just explained in Table 13. For every rupee of unexplained difference in Table 12F, practitioners should prepare a working paper trail linking the difference to: (a) the specific invoices involved; (b) the accounting year in which they were booked; (c) the GSTR-9 table where the corresponding ITC appears (Table 6A1, Table 6B, Table 8C, etc.); and (d) the GSTN FAQ or CBIC Circular relied upon to justify the treatment.

Fourth, file GSTR-9C after filing GSTR-9 — and verify Table 7J carefully. Before populating GSTR-9C, practitioners must confirm that Table 7J of the filed GSTR-9 correctly excludes Table 6A1 ITC and includes only current-year net ITC. An erroneous Table 7J creates a cascading error in Table 12E and consequently in Table 12F. Since GSTR-9 and GSTR-9C cannot be revised once filed, this verification is irreversible.

Fifth, the CBIC should issue a formal Circular providing statutory clarity on the treatment of Table 12B and Table 12F for FY 2024-25 and prospective years. Mere FAQs do not constitute binding legal authority and cannot protect taxpayers against departmental proceedings initiated on the basis of a Table 12F balance.

Conclusion:-

The cross-year ITC reporting paradox in GSTR-9C for FY 2024-25 is a genuine structural anomaly — not a theoretical concern. It arises from the well-intentioned insertion of Table 6A1 in GSTR-9 without a corresponding amendment to the reconciliation architecture of GSTR-9C. The result is a Form where Table 12B has lost its mathematical utility, Table 12F generates artificial differences, and thousands of taxpayers face the risk of assessment proceedings for reconciliation gaps that reflect compliant cross-year timing adjustments rather than genuine suppression of ITC or turnover.

So, my recommendation that CBIC issue a formal Circular:

(i) Confirming that Table 12F differences arising solely from the exclusion of Table 6A1 ITC from Table 7J of GSTR-9 shall not be construed as evidence of ITC misuse or suppression for the purposes of Sections 61, 65, 73, or 74 of the CGST Act, 2017;

(ii) Clarifying the correct treatment of prior-year ITC under each accounting methodology (accrual vs. cash) for the purposes of Tables 12A, 12B, and 12C;

(iii) Directing the GSTN to introduce a dedicated reconciling row in GSTR-9C (Table 12B1 or equivalent) specifically for ITC reported in Table 6A1 of GSTR-9, to eliminate the current structural mismatch; and

(iv) Providing that Table 13 explanations corroborated by the GSTN FAQ guidance shall constitute valid justification for Table 12F differences in departmental proceedings until the structural amendment is made.

Until such guidance is issued, the silent trap in Table 12F will continue to wound taxpayers who have done nothing wrong — which is precisely the outcome that the GST reconciliation framework was designed to prevent.
