GSTAT Kolkata Bench: How to File a GST Appeal (2026)
GSTAT Kolkata Bench opened 23 March 2026 for West Bengal, Sikkim and Andaman & Nicobar. Filing process, pre-deposit rules, jurisdiction and timelines.
For eight years there was nowhere to go
The Goods and Services Tax Appellate Tribunal was written into the CGST Act in 2017. Section 109 provided for it. Then, for the better part of a decade, it did not exist.
The consequence was ugly. A taxpayer who lost before the first appellate authority under Section 107 had no forum for a second appeal on facts. The only route was a writ petition to the High Court — which will not re-examine findings of fact, only jurisdictional error or breach of natural justice. Genuine factual disputes had nowhere to land, and demands accumulated behind them.
That has now changed. Following the appointment of judicial and technical members, the tribunal began operating in phases through 2026. The Kolkata Bench commenced functioning on 23 March 2026.
What the Kolkata Bench covers
The Kolkata Bench exercises jurisdiction over:
- West Bengal
- Sikkim
- The Andaman & Nicobar Islands
It sits at 2/5 Judges Court Road, Alipore, Kolkata, in the building formerly known as Sanchar Bhawan. The 31 July 2024 establishment notification provided for two benches at Kolkata for West Bengal.
Your bench is determined by the state of your GST registration. The first two digits of your GSTIN tell you: 19 is West Bengal. If your GSTIN begins 19, your appeal is filed at Kolkata, not Delhi and not Cuttack.
The rollout, in order
| Phase | Date | Benches |
|---|---|---|
| Phase 1 | 16 February 2026 | Principal Bench (New Delhi), Delhi State Bench, Cuttack (Odisha) |
| Phase 2 | 23 March 2026 | Kolkata (West Bengal, Sikkim, A&N) |
| Subsequent | Through 2026 | Remaining state benches, progressively |
Each bench issues its own public notice on commencement, so "the GSTAT is operational" is not a single national fact — it is bench by bench.
Who can appeal
You may appeal to the Tribunal if you are aggrieved by an order passed by:
- the Appellate Authority under Section 107, or
- the Revisional Authority under Section 108.
Note what is not appealable here. You cannot leapfrog. An original order under Section 73 or 74 goes first to the Section 107 appellate authority; only that authority's order comes to the Tribunal.
The pre-deposit
This is where appeals stall, and it is worth being blunt about the cash requirement before you start drafting.
Under Section 112 of the CGST Act:
- Appeal to a State Bench requires a pre-deposit of 10% of the disputed tax, over and above amounts already admitted and paid
- That pre-deposit is capped at ₹50 crore
- A further appeal to the Principal Bench attracts an additional 20% of the remaining disputed tax
Three points that catch people out:
- The percentage runs on tax in dispute, not on interest or penalty. A demand that is mostly penalty is cheaper to appeal than its headline suggests.
- It is cumulative. You already paid 10% at the Section 107 stage. This is on top.
- It is a precondition to filing, not something you settle later.
Procedure
Filing is governed by the GST Appellate Tribunal (Procedure) Rules, 2025, notified in the Official Gazette. Appeals are filed electronically through the GSTAT portal, and the Tribunal has published an e-filing user manual along with a helpdesk for technical issues.
Broadly:
- Compute limitation. Because the Tribunal became available so late, transitional timelines have applied to older orders. Check your specific position rather than assuming.
- Pay the pre-deposit and retain proof.
- Draft the appeal — memorandum, grounds of appeal, statement of facts, and the certified copy of the impugned order.
- File electronically on the GSTAT portal.
- Cure defects. Benches have been issuing defect rectification notices as filings ramp up; respond promptly or the appeal is not taken on record.
- Appear at the hearing, personally or through an authorised representative.
What this means practically for eastern India
Two things.
If you are holding an adverse Section 107 order and have been waiting for a forum, the forum exists now — and the clock is running. Waiting was defensible while there was no tribunal. It is not defensible any more.
And if you are currently at the notice stage — an ASMT-10, a DRC-01, a Section 73 or 74 show cause notice — the reply you file today is the record the Tribunal will read in two years. Appeals are won and lost on what went into the original reply. A thin, hurried ASMT-11 is very hard to repair later.
If your matter is still at notice stage, read our companion guide on GST show cause notices under Section 73 vs Section 74 before you draft the reply — it is the document both the appellate authority and the Tribunal will read first.
