Procedural Lapses in Appellate Filings: CESTAT Mumbai Mandates Strict Compliance with Form ST-4 in Service Tax Dispute

The intersection of substantive tax rights and procedural compliance forms the bedrock of indirect tax litigation in India. A recent judicial pronouncement by the Customs, Excise and Service Tax Appellate Tribunal (CESTAT), Mumbai, serves as a critical reminder of how administrative oversights—such as failing to properly fill out mandatory appellate forms—can derail an assessee's pursuit of justice. In the landmark matter of Salini NDT Services Pvt Ltd Vs Commissioner of CGST And Central Excise, the Tribunal navigated the delicate balance between enforcing strict procedural mandates and upholding the principles of natural justice.

This comprehensive analysis delves into the factual matrix, the statutory frameworks invoked, and the broader implications of the Tribunal's decision to remand the matter for fresh adjudication due to defective pleadings in Form ST-4.

The Genesis of the Dispute: Inter-Departmental Data Sharing

The origins of this protracted legal battle highlight a growing trend in Indian tax administration: the seamless exchange of intelligence between direct and indirect tax authorities. The dispute was ignited when the Central Board of Indirect Taxes and Customs (CBIC) received specific financial data from the Income Tax Department.

Triggering the Investigation

The Revenue department was alerted by the Income Tax Return (ITR) data filed by the assessee for the financial year FY 2016-17. Discrepancies between the income declared for direct tax purposes and the taxable value declared for indirect tax purposes often serve as a red flag for potential revenue leakage. Acting on this intelligence, the indirect tax authorities directed the assessee to produce comprehensive financial records.

The department specifically requisitioned critical documents, including Form 26AS, covering the period from FY 2016-17 to 2017-18 (upto June). Form 26AS, being a consolidated annual tax statement, is frequently utilized by indirect tax officers to cross-verify the quantum of services rendered and the corresponding receipts.

The Best Judgment Assessment

When the assessee failed to furnish the requested financial documentation, the department was left with no alternative but to initiate a best judgment assessment. Consequently, a comprehensive show cause notice was drafted and issued on 11.10.2021.

The authorities invoked the extended period of limitation under the proviso to Section 73(1) of the Finance Act, 1994. The notice alleged a significant short payment of service tax and proposed a total recovery demand of Rs. 25,42,189. This proposed demand was accompanied by the standard levies of applicable interest and statutory penalties under the provisions of the Finance Act, 1994.
