The Institute of Chartered Accountants of India (ICAI), through its GST & Indirect Taxes Committee, has released a comprehensive publication titled “Practical Guide to GST Adjudication and Appeals including GSTAT”, updated up to March 31, 2026.
The guide is designed as a practical resource for Chartered Accountants and tax professionals handling disputes under the GST regime. The publication has been revised from the earlier “Practical Guide to GST Disputes” and now carries expanded coverage specifically relating to GST adjudication, appeals and Tribunal procedures. It also includes guidance on online filing processes before GSTAT.
According to ICAI, the publication addresses practical challenges arising in tax demands, investigations, appeals and litigation strategy and aims to equip professionals with tools required for effective representation before authorities and appellate forums.
The guide spans twelve chapters and covers diverse aspects of GST litigation including general legal principles, principles of evidence, scope of assessment and investigation, litigation strategy, show cause notices, appellate remedies, drafting and pleadings, revisionary proceedings, appearance before authorities and the GSTAT filing process.
One of the major observations in the guide is that Chartered Accountants have been recognised as authorized representatives under GST law and may represent taxpayers before tax authorities and the Tribunal. The publication emphasizes that GSTAT serves as the final fact-finding authority and therefore professional representation at that stage assumes substantial importance.
The publication extensively discusses the evolving role of Chartered Accountants in GST litigation. It notes that CAs may assist clients at multiple stages, including departmental audits, investigations, drafting replies to show cause notices, representation during adjudication proceedings, appellate proceedings and support functions before High Courts and the Supreme Court.
The guide distinguishes between different stages of representation and clarifies that during audits or investigations a CA generally acts as a communication channel rather than representing the taxpayer directly. However, during adjudication and post-adjudication proceedings, the CA can actively draft replies, file appeals and appear before authorities and tribunals.
Significant emphasis has also been placed on ethics and professional conduct. The guide states that CAs must avoid supporting unlawful tax positions, maintain independence and recuse themselves where conflicts of interest arise. It warns against plagiarism, unauthorized representation and unethical practices while stressing integrity as a central requirement of professional conduct.
The publication further provides an extensive discussion on principles of natural justice and procedural safeguards. It reiterates that taxpayers should receive proper notices, be granted opportunities of hearing and receive reasoned orders dealing with contentions raised during proceedings. The guide specifically discusses the principles of Audi Alteram Partem (hear the other side), Nemo Judex in Causa Sua (no person should be a judge in his own cause), and the requirement for reasoned decisions.
An important part of the publication is its treatment of evidentiary principles in tax litigation. Referring to the Bharatiya Sakshya Adhiniyam, 2023, the guide explains concepts relating to burden of proof, relevance of facts and evidentiary requirements in establishing exemptions, export claims and other tax positions.
The publication also incorporates references to Bharatiya Nyaya Sanhita, 2023 provisions concerning public servants and proceedings before authorities. It discusses offences such as avoidance of summons, non-production of documents, providing false information and obstruction of public servants.
Further, the guide provides practical “Do’s and Don’ts” for tax professionals, advising practitioners to maintain documented mandates, preserve reference materials, verify legal sources, maintain case records and continuously update themselves on legal developments. It simultaneously warns against relying merely on headnotes, supporting unsustainable tax positions and using unauthenticated legal texts.
The ICAI publication arrives at a critical stage of GST evolution where increasing litigation and the operationalisation of GSTAT are expected to reshape tax dispute resolution in India. By combining procedural guidance, legal principles and practical illustrations, the publication seeks to act as a roadmap for professionals navigating the expanding GST adjudication and appellate framework.
