Appeal to GST Tribunal (GSTAT) in India: Process, Grounds & Timeline (2026)

What Is GSTAT?

The GST Appellate Tribunal (GSTAT) is a quasi-judicial body established under Section 109 of the CGST Act, 2017. It hears appeals against orders passed by the Appellate Authority under Section 107 and the Revisional Authority under Section 108.

GSTAT consists of a National Bench at New Delhi for inter-state matters, and State Benches and Area Benches for intra-state matters. Each bench includes a Judicial Member and a Technical Member.

When Can You Appeal to GSTAT?

An appeal lies before GSTAT against orders passed by the First Appellate Authority under Section 107, and orders passed by the Revisional Authority under Section 108. You cannot directly approach GSTAT without first exhausting the remedy before the Appellate Authority.

Who Can File an Appeal?

Both the taxpayer and the GST Department can file an appeal. The taxpayer files under Section 112(1) of the CGST Act. The department files under Section 112(3) when it believes the order is erroneous and prejudicial to revenue.

Time Limit for Filing an Appeal

An appeal before GSTAT must be filed within 3 months from the date of communication of the order. The tribunal has discretionary power to condone delay if sufficient cause is shown, but this is not automatic.

Pre-Deposit Requirement

Before an appeal is admitted, the appellant must pay a pre-deposit of 20% of the disputed tax amount in addition to amounts already paid at the first appeal stage. The maximum pre-deposit cap is ₹50 crore each of CGST and SGST/UTGST. This is mandatory and is not waived except in exceptional circumstances.

Grounds for Appeal

• Errors of law — incorrect interpretation or application of GST provisions

• Errors of fact — findings not supported by evidence on record

• Procedural violations — non-observance of principles of natural justice

• Jurisdictional errors — orders passed without or in excess of jurisdiction

• Arbitrary or perverse findings — conclusions no reasonable authority could reach on the evidence

GSTAT does not entertain fresh grounds not raised before the lower authorities unless they are purely legal in nature.

Documents Required for Filing

• Copy of the order being appealed

• Copy of the order of the first Appellate Authority

• Certified copy of the demand notice

• Proof of pre-deposit payment

• Grounds of appeal with supporting legal submissions
