GSTAT 2026: India's GST Appellate Tribunal Now Operational Across Multiple State Benches

The Goods and Services Tax Appellate Tribunal (GSTAT), constituted under Section 109 of the Central Goods and Services Tax Act, 2017, has commenced adjudicatory operations across India in 2026 after years of delay since the GST regime was introduced in July 2017. The Principal Bench in New Delhi began hearing cases on 16 February 2026, followed by the phased operationalisation of State Benches in Kolkata, Chennai, Hyderabad, Agra, and other locations. The GSTAT fills a critical gap in the GST dispute resolution architecture, providing taxpayers with an appellate forum between the first appellate authority (Commissioner of Appeals) and the High Courts. For nearly seven years, the absence of a functioning GSTAT meant that thousands of GST disputes remained unresolved, with taxpayers forced to either accept adverse first appellate orders or seek expensive and time-consuming writ remedies before High Courts.

Structure of the GSTAT: Principal Bench and State Benches

The GSTAT operates through a Principal Bench located in New Delhi and 31 State Benches spread across 45 locations throughout India. Each bench comprises four members: two Judicial Members, one Technical Member (Centre) nominated by the Central Government, and one Technical Member (State) nominated by the respective State Government. This four-member composition ensures that both the central and state perspectives on GST matters are represented in appellate proceedings, reflecting the dual nature of GST as a tax levied concurrently by the Centre and the States. The Principal Bench has exclusive jurisdiction over appeals where one of the issues involves the place of supply, a determination that affects the distribution of tax revenue between the Centre and the States. All other appeals lie before the State Bench of the state where the taxpayer is registered. The President of the GSTAT, who presides over the Principal Bench, also exercises administrative supervision over all State Benches, including the allocation of benches to specific locations and the transfer of members between benches.

Phased Operationalisation: Which Benches Are Now Functional

The GSTAT launched its first phase of operations on 16 February 2026 with the Principal Bench in New Delhi and the State Bench at Cuttack (covering Odisha). The Delhi State Bench began operations from temporary premises shortly thereafter, as notified under Public Notice No. 01/2026. The Kolkata Bench, covering West Bengal, Sikkim, and the Andaman and Nicobar Islands, commenced operations on 23 March 2026. The Chennai Bench became operational on 1 April 2026, handling appeals from Tamil Nadu and Puducherry. The Agra Bench, covering 15 districts of Uttar Pradesh, was notified as functional on 6 April 2026. The Hyderabad Bench, one of the most anticipated given the volume of GST disputes in Telangana, commenced operations on 20 April 2026 from temporary premises at GST Bhavan, Basheerbagh. Additional benches in other states are expected to become operational in phases during the remainder of 2026, with the government targeting full national coverage by the end of the calendar year.

Filing Appeals: Procedure, Timelines, and the E-Courts Portal

Appeals to the GSTAT must be filed within three months from the date of communication of the order of the first appellate authority. The government has the same three-month window to file appeals against orders favourable to the taxpayer. A condonation of delay of up to one month is available on sufficient cause being shown. The pre-deposit requirement for filing an appeal before the GSTAT is 20 per cent of the disputed tax amount (in addition to the amount already deposited during the first appeal), subject to a maximum cap. The GSTAT e-Courts Portal is a key feature of the new tribunal's infrastructure, enabling taxpayers and practitioners to file appeals online, track case progress, access hearing schedules, and participate in hearings through video conferencing. The portal supports electronic filing of documents, digital signatures, and online payment of fees. For practitioners accustomed to physical filing before other tax tribunals, the GSTAT's digital-first approach represents a significant modernisation of the appellate process.

Impact on Pending GST Disputes and the Backlog Problem

The operationalisation of the GSTAT addresses a massive backlog of GST disputes that have accumulated since 2017. During the nearly seven-year period when the GSTAT was not functional, taxpayers who received adverse orders from the Commissioner of Appeals had limited options. Some filed writ petitions before High Courts, which added to the already overburdened High Court dockets. Others deposited the disputed tax under protest and awaited the GSTAT's establishment. The government addressed this by extending the limitation period for filing appeals before the GSTAT, providing taxpayers with a fresh window to file appeals against orders that were passed during the period when no appellate forum was available. The Registrar Court at each bench handles preliminary matters including defect rectification in appeals, ensuring that cases are ready for substantive hearing when they come before the bench. Given the volume of pending disputes, the GSTAT is expected to prioritise cases involving significant revenue implications and those where taxpayers have been waiting the longest for resolution.

What Taxpayers and Practitioners Should Do Now

Taxpayers with pending GST disputes should review all adverse first appellate orders to determine which are eligible for appeal before the GSTAT. The extended limitation window means that many orders that were previously time-barred may now be appealable. Practitioners should register on the GSTAT e-Courts Portal and familiarise themselves with the online filing procedure, as physical filing may not be available at all bench locations. The pre-deposit requirement should be factored into cash flow planning, as the 20 per cent additional deposit can be substantial for high-value disputes. Taxpayers should also note that the GSTAT's jurisdiction is limited to questions of fact and law arising under the CGST Act, SGST Acts, IGST Act, and the Compensation Cess Act. Constitutional challenges to GST provisions remain within the exclusive domain of the High Courts. For disputes involving place of supply issues, the appeal must be filed before the Principal Bench in New Delhi, regardless of where the taxpayer is registered. The establishment of the GSTAT is a welcome development that strengthens the rule of law in indirect taxation and provides taxpayers with an accessible, specialised forum for the resolution of GST disputes.
