Return discrepancies alone cannot establish GST liability without net ITC verification, primary-record reconciliation, and identification of common credit.
GST demands founded solely on discrepancies between Form GSTR-3B, GSTR-2A, GSTR-9 and GSTR-9C require verification of underlying records. Excess input tax credit must be assessed on the net position after giving effect to disclosed reversals; gross-credit comparisons alone do not establish revenue loss. Output-tax differences require reconciliation with sales ledgers, invoices and financial books. Under Rules 42 and 43, proportional reversal applies only after specific and actual common credit is identified and segregated. Unreconciled portal data and treating all credit as common cannot determine tax, interest or penalty liability; de novo verification is required.
Issues: (i) Whether an alleged excess input tax credit claim can be sustained merely by comparing Form GSTR-3B with Form GSTR-2A without verifying input tax credit reversals and the net credit position; (ii) Whether the difference between Table 9 of Form GSTR-9 and Table 9P of Form GSTR-9C establishes short-paid output tax without reconciliation of the underlying records; (iii) Whether a demand for short reversal of input tax credit under Rules 42 and 43 can be sustained without identifying and segregating actual common credit.
Issue (i): Whether an alleged excess input tax credit claim can be sustained merely by comparing Form GSTR-3B with Form GSTR-2A without verifying input tax credit reversals and the net credit position.
Analysis: A demand under Section 73 requires verification of the actual net input tax credit position. The return data showed that input tax credit reversals in Table 4(B) of Form GSTR-3B exceeded the credit availed. A comparison of gross credit figures with Form GSTR-2A, while disregarding those reversals, did not determine whether any excess credit remained or whether there was an actual revenue loss.
Conclusion: The alleged excess input tax credit demand was unsustainable without giving effect to reversals and determining the net input tax credit position.
Issue (ii): Whether the difference between Table 9 of Form GSTR-9 and Table 9P of Form GSTR-9C establishes short-paid output tax without reconciliation of the underlying records.
Analysis: The two return fields reflected different reporting parameters, including the effect of input tax credit reversals. The disclosed reconciliation explanation was not scrutinised, and the difference was treated as unpaid tax without verification of sales ledgers, tax invoices, and financial books. A portal-based comparison alone was insufficient to determine output-tax liability.
Conclusion: The return mismatch did not by itself establish short-paid tax and required a detailed factual reconciliation.
Issue (iii): Whether a demand for short reversal of input tax credit under Rules 42 and 43 can be sustained without identifying and segregating actual common credit.
Analysis: Rules 42 and 43 require identification of specific credit and common credit before applying the exempt-to-taxable turnover ratio to the actual common input tax pool. The demand proceeded by treating the entire input tax credit as common credit and without verifying the substantial reversals disclosed in the returns.
Conclusion: The proposed proportional reversal was invalid because the requisite segregation and verification of common credit had not been undertaken.
Final Conclusion: The demand determinations rested on unreconciled return discrepancies and omitted essential verification of primary records; fresh de novo verification is necessary before any tax, interest, or penalty liability can be determined.
Ratio Decidendi: A GST demand founded on return discrepancies cannot be sustained without verification of the net input tax credit position after accounting for reversals and, under Rules 42 and 43, identification of actual common credit before applying proportional reversal.
