After eight years of waiting, India’s GST Appellate Tribunal is finally operational. This guide explains what GSTAT is, who can appeal, how to file, pre-deposit rules, and what the June 2026 backlog deadline means for businesses in Bihar.
GSTAT stands for Goods and Services Tax Appellate Tribunal. It is the statutory second-tier appellate body for GST disputes in India, established under Section 109 of the Central Goods and Services Tax (CGST) Act, 2017. GSTAT sits between the First Appellate Authority (Appellate Commissioner) and the High Court in the GST appeal hierarchy.
In simple terms: if a taxpayer loses a GST dispute at the first appeal level — before the Appellate Commissioner — the next step is GSTAT. It is a specialised tribunal, staffed by Judicial Members (retired High Court judges or senior advocates) and Technical Members (experienced IRS officers), designed to deliver faster, more expert decisions on GST disputes than overloaded High Courts.
Each GSTAT bench comprises two Judicial Members and two Technical Members — one Technical Member from the Centre and one from the State — ensuring expertise on both legal and tax policy dimensions of every dispute.
| Stage | Forum | Governing Section | Pre-Deposit |
|---|---|---|---|
| Adjudication | Adjudicating Officer (GST Officer) | S.73 / S.74, CGST Act | — |
| First Appeal | First Appellate Authority (Appellate Commissioner) | S.107, CGST Act | 10% of disputed tax |
| Second Appeal | GSTAT (GST Appellate Tribunal) | S.112, CGST Act | 20% of remaining disputed tax (capped at ₹50 Cr) |
| Further Appeal | High Court (Patna HC for Bihar) | S.117, CGST Act | As directed by Court |
| Final Appeal | Supreme Court of India | S.118, CGST Act | As directed by Court |
When GST was introduced in July 2017, the law always envisaged GSTAT as the second tier of appeals. However, GSTAT remained non-functional for over eight years due to a series of legislative and judicial complications — including disputes over the eligibility criteria and selection process for Technical Members, which were challenged before various High Courts.
During this prolonged absence, taxpayers who lost at the first appeal level had no choice but to approach High Courts directly through writ petitions under Article 226 of the Constitution. This was never intended as the routine mechanism for second appeals. It was expensive, slow, and technically demanding — particularly for MSMEs, traders, and small businesses who lacked the resources to pursue High Court litigation.
The result was a massive accumulation of unresolved GST disputes across India, with thousands of cases pending before various High Courts on matters that GSTAT was always designed to handle.
Finance Minister Nirmala Sitharaman, at GSTAT’s inauguration on 24 September 2025, emphasised that the Tribunal aims to reduce legal friction, bring greater simplicity, address delays in litigation, and help businesses — particularly MSMEs and exporters — manage cash flows with greater confidence.
GSTAT is a creature of statute. Its constitution, powers, and procedure are governed by a set of specific legal provisions:
Section 109 mandates the constitution of the Goods and Services Tax Appellate Tribunal and its benches. The Principal Bench is located in New Delhi. Up to 31 State Benches have been notified at locations across India, including a dedicated Patna Bench for Bihar.
Section 110 prescribes qualifications for the President (a retired Supreme Court or Chief Justice of a High Court), Judicial Members (retired High Court judges or senior advocates of 10 years’ standing), and Technical Members from the Central and State services.
Justice (Retd.) Sanjaya Kumar Mishra, former Chief Justice of Jharkhand High Court, was appointed as the President of GSTAT in May 2024. In August 2025, the Government appointed 31 Technical Members and 52 Judicial Members, providing the full complement for GSTAT benches across India.
Section 112 is the primary provision under which second appeals are filed before GSTAT. It sets out the eligibility, limitation period, pre-deposit requirements, and the Tribunal’s authority to hear and decide appeals.
The complete procedural framework for GSTAT is governed by the Goods and Services Tax Appellate Tribunal (Procedure) Rules, 2025, notified on 24 April 2025 vide Gazette Notification No. GSR 256(E). These rules prescribe the format for appeals, hearing procedure, adjournment limits (maximum 3), the e-filing process, and cross-objection timelines.
Orders of GSTAT State Benches can be challenged before the respective High Court under Section 117 on substantial questions of law. Orders of the Principal Bench go to the Supreme Court under Section 118.
Under Section 112 of the CGST Act, the following persons can file an appeal before GSTAT:
Any registered or unregistered person who has received an order from the First Appellate Authority (Appellate Commissioner) and is aggrieved by that order — whether the appeal was dismissed, partially allowed, or the first authority enhanced the demand — can approach GSTAT.
The Commissioner of CGST or SGST can also file an appeal before GSTAT against a first appellate order that is considered erroneous or contrary to the interest of revenue. Departmental appeals are subject to the same procedural requirements.
The opposing party in an existing GSTAT appeal may file a cross-objection within 45 days of receiving the notice of the original appeal — even if they could not have independently filed an appeal due to limitation or
GSTAT has jurisdiction to hear appeals against orders passed by the First Appellate Authority under Section 107 of the CGST Act. The types of original disputes that can ultimately reach GSTAT include:
| Type of Dispute | Common Issues | Appealable to GSTAT? |
|---|---|---|
| GST Demand Orders (S.73 / S.74) | Tax demand, interest, penalty on assessment | Yes |
| Input Tax Credit Disallowance | ITC reversal, GSTR-2A mismatch, S.16 violations | Yes |
| GST Penalty Orders | E-way bill, late filing, fraud penalties | Yes |
| Refund Rejection Orders | Export refunds, inverted duty refunds | Yes |
| Classification / Rate Disputes | Incorrect tax rate applied, HSN classification | Yes |
| Registration Cancellation | Suo motu cancellation orders by department | Yes (after first appeal) |
| Place of Supply Disputes | IGST vs CGST+SGST characterisation | Principal Bench |
| Orders passed ex parte | Where assessee did not appear | Yes |
| Advance Ruling conflicts (NAAR) | Conflicting rulings from 2+ state AARs | Principal Bench (from Apr 2026) |
It is important to note that GSTAT can hear appeals on both questions of law and questions of fact — unlike High Court appeals under Section 117, which are limited to substantial questions of law. This makes GSTAT the more comprehensive forum for disputing incorrect factual findings made by lower authorities.
GSTAT is vested with wide powers to ensure effective resolution of GST disputes. These include:
GSTAT can confirm the order of the First Appellate Authority, modify it, set it aside entirely, or remand the matter back to the lower authority for fresh consideration. It has full authority to re-examine both the facts and the law applicable to a dispute.
On an application by the appellant, GSTAT has the power to stay the recovery of the demand pending disposal of the appeal. This is a significant relief for taxpayers facing aggressive recovery action by the department while their appeal is being heard.
GSTAT can consider cross-objections filed by the other party and grant appropriate relief — including in cases where the respondent seeks enhancement of the demand or order.
Under the GSTAT Procedure Rules, 2025, additional evidence can be admitted only in exceptional circumstances — such as where the evidence was not available at the time of the original proceedings, or where it was wrongly rejected by the lower authority. This power is exercised sparingly.
GSTAT has the powers of a civil court for the purposes of: summoning and enforcing attendance of witnesses, examining witnesses on oath, compelling production of documents, and receiving evidence on affidavit.
From April 2026, the Principal Bench of GSTAT acts as the National Appellate Authority for Advance Rulings (NAAR). This means that where two or more State Advance Ruling Authorities have given conflicting rulings on the same question, a taxpayer can approach the Principal Bench for a binding national ruling. This eliminates the problem of divergent GST classifications across states — a long-standing frustration for businesses operating across multiple states.
GSTAT appeals are filed electronically through the GSTAT e-filing portal at efiling.gstat.gov.in. The process under the GSTAT (Procedure) Rules, 2025, is as follows:
Obtain the First Appellate OrderThe appeal to GSTAT is filed against an order passed by the First Appellate Authority under Section 107. Ensure you have a certified copy of this order. Note the date of communication — the 3-month limitation clock starts from this date.
Assess Eligibility and LimitationConfirm that the appeal is filed within 3 months of receiving the order. For orders passed before 1 April 2026, the special backlog window closes on 30 June 2026. Compute the correct limitation date in calendar months — not 90 days.
Compute and Pay Pre-DepositCalculate 20% of the remaining disputed tax (the disputed amount minus what was already deposited at the first appeal stage). Ensure the pre-deposit does not exceed ₹50 crore. Pay through the GST portal and retain proof of payment.
Prepare the Grounds of AppealDraft the statement of facts, grounds of appeal, and supporting legal arguments. Identify the relevant provisions of the CGST Act, applicable circulars, and judicial precedents. This is the most critical document in the appeal — errors here are difficult to remedy later.
Compile Supporting DocumentsGather: the impugned first appellate order, the original adjudication order, GST returns (GSTR-1, GSTR-3B), ITC ledger, invoices and purchase records, pre-deposit payment evidence, and any other documents relied upon in the lower proceedings.
File in Form GST APL-05 on the GSTAT PortalLog in to efiling.gstat.gov.in and file the appeal in Form GST APL-05. Upload all documents, the grounds of appeal, and the pre-deposit proof. Regardless of the number of show-cause notices covered by the original order, a single appeal form is filed.
Receive Acknowledgement and Attend HearingUpon filing, an acknowledgement is generated. GSTAT issues notice for hearing. The Rules allow a maximum of 3 adjournments — after which the appeal may be decided ex parte or dismissed. GSTAT operates in hybrid mode allowing both physical and video-conference hearings.
Pre-deposit is a mandatory condition for admission of a GSTAT appeal. Without the correct pre-deposit, the appeal will not be admitted. The rules are as follows:
| Appeal Stage | Pre-Deposit Required | Cap |
|---|---|---|
| First Appeal (Appellate Commissioner) | 10% of disputed tax under CGST + 10% under SGST | No statutory cap at this stage |
| Second Appeal — GSTAT (S.112) | 20% of remaining disputed tax (after first appeal deposit) | ₹50 crore (total, including first appeal deposit) |
| Appeal against State Bench order to Principal Bench | 20% of disputed amount not already deposited | ₹50 crore |
| NAAR Appeal (Principal Bench) | ₹10,000 filing fee only | No tax pre-deposit required |
The pre-deposit is not a penalty — it is a condition for admission of the appeal and is refundable with interest if the taxpayer succeeds. However, the cash flow impact of the pre-deposit must be factored into the decision to appeal, particularly for MSMEs and smaller businesses.
The Patna Bench of GSTAT has been constituted to serve as the appellate tribunal for all GST disputes arising in Bihar. It is the only bench for Bihar — all 38 districts fall within its jurisdiction, with no circuit bench arrangement. Taxpayers from Muzaffarpur, Gaya, Bhagalpur, Darbhanga, Purnia, and every other district in Bihar must file before the Patna Bench.
GSTAT benches across India are being operationalised in phases throughout 2026. The Principal Bench in New Delhi and the Delhi, Cuttack, and Kolkata benches were among the first to begin operations. The Patna Bench has been allocated its Judicial and Technical Members and is in the process of operationalisation as part of the ongoing national rollout.
Due to the prolonged absence of GSTAT, thousands of first appellate orders passed between 2017 and early 2026 could not be challenged before the Tribunal. The government has provided a special window for such backlog cases: taxpayers whose first appellate orders were passed before 1 April 2026 have until 30 June 2026 to file their GSTAT appeal.
This is a hard deadline. Missing it means the adverse order becomes final and enforceable, with no further remedy except a writ petition before the Patna High Court — which is a more limited and expensive route. Businesses in Bihar with pending adverse orders should act immediately.
Even after GSTAT’s operationalisation, the Patna High Court retains jurisdiction under Section 117 of the CGST Act to hear appeals from GSTAT State Bench orders on substantial questions of law. The High Court also retains its writ jurisdiction under Article 226 for cases involving violation of natural justice, jurisdictional error, or constitutional validity of GST provisions.
GSTAT represents a fundamental improvement in the GST dispute resolution framework for Indian taxpayers. The key benefits are:
Each GSTAT bench combines Judicial Members (retired judges / senior advocates) with Technical Members (senior IRS officers). This composition ensures that both the legal dimensions and the technical tax policy aspects of every dispute receive expert consideration — something a generalist High Court bench cannot always provide.
GSTAT hearings are subject to strict timelines. The Rules limit adjournments to a maximum of 3, reducing the indefinite delays that characterised High Court GST writ petitions. Faster resolution improves cash flow certainty for businesses.
Pursuing a GST dispute before the High Court requires expensive legal representation and follows the High Court’s own complex procedural rules. GSTAT proceedings are designed to be more accessible, particularly for MSMEs and smaller taxpayers.
Unlike the High Court (which reviews only substantial questions of law), GSTAT can re-examine the factual basis of a demand — whether the officer’s factual conclusions were correct, whether the evidence was properly assessed, and whether the computation of tax is accurate.
GSTAT has explicit power to stay recovery proceedings pending disposal of the appeal. This protects taxpayers from coercive recovery action while their case is being heard — a protection that was difficult to obtain without filing a writ petition before the High Court.
All GSTAT filings are electronic through the GSTAT portal. Hearings are conducted in hybrid mode — both physical and video conferencing — reducing travel time and costs for taxpayers from districts outside Patna, Bengaluru, Delhi or wherever their bench is located.
From April 2026, the Principal Bench of GSTAT acts as the National Appellate Authority for Advance Rulings. Conflicting rulings between state AAR authorities can now be resolved at a single national level, bringing consistency to GST classification and taxability determinations across all states.
Thousands of GST writ petitions were clogging High Courts across India. GSTAT absorbs these cases into a dedicated forum, freeing High Courts for cases that genuinely raise constitutional or jurisdictional questions, and reducing waiting times across the board.
