GSTAT Appeal Filing Deadline June 30, 2026: A Complete Guide to Notification S.O. 4220(E) for Pre-April 1 Backlog Orders

The GST Appellate Tribunal is finally operational, and the clock is ticking. If your business or your client has a first-appeal order passed before April 1, 2026 that still does not have a second appellate remedy exercised, the one-time window to file that appeal with the GST Appellate Tribunal (GSTAT) closes on June 30, 2026. That is 67 days away as of April 24, 2026. Miss it, and the appeal is barred. This article is a practical, step-by-step advisory for CAs, tax heads, and founders on how to use Notification S.O. 4220(E) dated September 17, 2025 to clear legacy GST disputes before the window shuts.

Key Takeaways

• Notification: Ministry of Finance S.O. 4220(E) dated September 17, 2025, issued under Section 112(1) of the Central Goods and Services Tax Act, 2017.
• Deadline: June 30, 2026 for any order communicated before April 1, 2026 by the First Appellate Authority (Section 107) or Revisional Authority (Section 108).
• Post-April 1, 2026 orders: Standard limitation of three months from the date of communication applies.
• Form: Electronic Form GST APL-05 on the GSTAT e-filing portal at efiling.gstat.gov.in. Manual filing is permitted only with express Registrar authorisation.
• Pre-deposit: 10% of the disputed tax, capped at Rs 20 crore each for CGST and SGST. For penalty-only disputes, 10% of the penalty with no cap. Payment only through the Electronic Cash Ledger.
• Action for CAs: Inventory every pre-April 1, 2026 first-appeal order in your client portfolio, assess merits, raise pre-deposit funds, and draft APL-05 grounds well before the June deadline to avoid the last-mile rush.

Why June 30, 2026 Matters

The GSTAT, constituted under Section 109 of the CGST Act, was legally mandated since July 2017 but remained non-operational for almost eight years. Over 4 lakh first-appeal orders accumulated during that period with no second appellate forum. Taxpayers aggrieved by First Appellate Authority orders had no option other than writ petitions before the High Courts, which added to litigation costs and clogged the constitutional courts.

With the Principal Bench in New Delhi and 31 State Benches now physically functional across 45 locations, the Government issued S.O. 4220(E) to provide a transitional runway. Orders communicated on or before March 31, 2026 benefit from a one-time extended window ending June 30, 2026. Orders communicated on or after April 1, 2026 are subject to the normal three-month limitation under Section 112(1).

This is a hard deadline. There is no mechanism in the notification for automatic condonation beyond June 30, 2026. While the Tribunal retains discretionary powers under Section 112(6) to condone delays of up to three additional months on sufficient cause, relying on discretion is a weak compliance strategy, especially when the same Tribunal is inundated with backlog filings from thousands of taxpayers.

Who Should File Before June 30, 2026

The deadline applies to any person aggrieved by:

• An order of the First Appellate Authority under Section 107 of the CGST Act or the corresponding SGST Act, communicated before April 1, 2026.
• An order of the Revisional Authority under Section 108 of the CGST Act or the corresponding SGST Act, communicated before April 1, 2026.

This covers taxpayers as well as the department. The Department may file departmental appeals in Form GST APL-07. For most CA practices, the primary focus will be taxpayer appeals in Form APL-05.

If your client received a Section 107 order in, say, October 2023 and chose to wait for the GSTAT to be constituted rather than approach the jurisdictional High Court under Article 226, June 30, 2026 is the final statutory opportunity to pursue that appeal. If your client filed a writ petition challenging the same order that is now pending before the High Court, you will need to make a strategic call: many High Courts have been disposing writ petitions with a direction to file before the GSTAT once it was operational.

Where to File: GSTAT Bench Jurisdiction

Benches are allocated by subject matter and territorial jurisdiction.

• Principal Bench, New Delhi: Exclusive jurisdiction over place-of-supply disputes irrespective of the State in which the order was passed.
• State Benches: 31 State Benches across 45 locations cover all other matters within their territorial jurisdiction. The appellant must file before the Bench that exercises jurisdiction over the State where the first-appeal order was passed.

Confirm the allocated Bench and location for your State before drafting the grounds of appeal. The GSTAT portal publishes the current list at efiling.gstat.gov.in and the official website of the Tribunal maintains the updated bench-wise jurisdiction schedule.

Pre-Deposit: The Biggest Compliance Trap

Pre-deposit under Section 112(8) is a jurisdictional condition. Without proof of deposit, the appeal is not maintainable.

Type of Demand	Pre-Deposit Percentage	Maximum Cap
Tax with interest, fees, penalty	10% of disputed tax	Rs 20 crore each for CGST and SGST
Penalty only (no tax component)	10% of penalty	No cap (effective April 1, 2025)

The pre-deposit made before the First Appellate Authority under Section 107 (10% of tax, capped at Rs 25 crore each for CGST and SGST) is in addition to the pre-deposit at the Tribunal stage. In other words, if your client is appealing a confirmed tax demand of Rs 10 crore, the cumulative pre-deposit at the appellate stage and the Tribunal stage is Rs 1 crore plus Rs 1 crore, that is Rs 2 crore, before the Tribunal can hear the matter.

Crucial rule: The Tribunal pre-deposit can only be made through the Electronic Cash Ledger. Input tax credit in the Electronic Credit Ledger cannot be utilised. Plan cash flow accordingly. Many MSME clients have been caught off guard by this working capital hit.

Step-by-Step GSTAT Appeal Filing Checklist

1. Identify the universe of pending orders. Run a portfolio sweep: list every first-appeal order received by each GSTIN you advise that was communicated before April 1, 2026 and that has not yet been appealed or abandoned. Flag the dates of communication to prioritise those closest to June 30, 2026.
2. Assess merits and quantum. For each order, prepare a one-page appeal memo: issue, amount confirmed, pre-deposit required, merits grade (strong, medium, weak), and business decision (appeal or accept). Weak-merits appeals with high pre-deposit may not be worth the working capital hit.
3. Raise the pre-deposit. Fund the Electronic Cash Ledger for each GSTIN. Recall that 10% of tax must be deposited via cash, not credit. Cash ledger credit is state-specific.
4. Prepare Form GST APL-05. Grounds must be consecutively numbered, concise, and must clearly refer to the impugned order, the first appellate order, and the revisional order (if any). Avoid copy-pasting grounds from the Section 107 appeal. The Tribunal looks for fresh legal formulations.
5. Assemble the documents. Certified copy of the impugned order (the order sought to be challenged), certified copy of the order-in-original if needed, proof of pre-deposit challan, document index, and translations of any non-English annexures.
6. Register on the portal. Register at efiling.gstat.gov.in with the appellant PAN, authorised representative e-signature, and contact details. The portal then issues a system-generated acknowledgment with an appeal serial number.
7. File electronically. Upload the signed APL-05, the documents, and the pre-deposit challan. Manual filing is available only on Registrar permission, so electronic filing is the default path.
8. Track the case. Maintain a portfolio tracker with appeal serial number, GSTIN, issue, stage, and next date of hearing. GSTAT hearings are expected to follow a staggered bench schedule.

Strategic Considerations

Should a Writ Petition be Withdrawn?

If a writ petition challenging the same first-appeal order is pending before the High Court, the High Court will typically direct the petitioner to avail the Tribunal remedy. Rather than wait for such a direction, consider filing the GSTAT appeal well in advance of June 30, 2026 and seeking permission to withdraw the writ. This avoids the risk of a High Court disposal order beyond the June deadline, which could leave the appeal timeline already exhausted.

Departmental Appeals and Cross-Objections

The department can file departmental appeals in APL-07 for orders where it is aggrieved. If the department has filed or is likely to file an appeal on a particular matter, your client can file cross-objections. The deadline for cross-objections is 45 days from the date of communication of the departmental appeal.

Multiple Orders for the Same GSTIN

Where the same GSTIN has multiple first-appeal orders for different tax periods, each order requires a separate APL-05 with its own pre-deposit. Do not club.

Stay of Recovery

Filing the APL-05 with the statutory pre-deposit operates as an automatic stay on recovery of the balance tax, interest, and penalty under Section 112(9). Ensure that the State GST officer is informed of the appeal filing, especially if recovery proceedings under Section 79 are underway.

Common Drafting Mistakes in APL-05

• Copying grounds verbatim from the Section 107 appeal without re-framing for the Tribunal level.
• Raising grounds that were not argued before the First Appellate Authority (the Tribunal may admit fresh legal grounds but not fresh factual grounds).
• Failing to state the amount in dispute accurately, which causes a mismatch with the pre-deposit and leads to an objection on maintainability.
• Not enclosing the certified copy of the first-appeal order. A photocopy is not sufficient.
• Missing the challan number and CIN of the pre-deposit in the APL-05 form.

FAQ: GSTAT Appeal Filing Under S.O. 4220(E)

What if my first-appeal order was communicated on March 31, 2026?

It falls within the scope of S.O. 4220(E) because it was communicated before April 1, 2026. You have until June 30, 2026 to file the APL-05.

What if my first-appeal order is communicated on April 2, 2026?

The standard three-month period under Section 112(1) applies. The last date is July 2, 2026. The June 30, 2026 transitional window does not apply.

Can the June 30, 2026 deadline be extended?

S.O. 4220(E) itself is a one-time transitional measure. The Tribunal retains discretionary power under Section 112(6) to condone a further delay of up to three months on sufficient cause. Do not treat that discretion as a default entitlement. Plan to file before June 30.

Can I pay the pre-deposit using Input Tax Credit?

No. The pre-deposit at the Tribunal stage must be paid through the Electronic Cash Ledger. ITC in the Electronic Credit Ledger cannot be adjusted.

What happens if I miss the June 30, 2026 deadline?

The Tribunal may refuse to admit the appeal on the ground of limitation. Your remedy then narrows to a writ petition before the High Court, and High Courts are unlikely to entertain writs where the statutory Tribunal remedy was available and not availed.

Does the pre-deposit earn interest if the appeal succeeds?

Yes. Upon a successful appeal, the department refunds the pre-deposit with interest at the prescribed rate under Section 115 of the CGST Act.

Is physical filing available?

Electronic filing through efiling.gstat.gov.in is mandatory. Physical filing is permitted only on explicit written permission from the Tribunal Registrar, typically in exceptional circumstances such as portal outages.

What CAs and Founders Should Do This Week

1. Today or tomorrow, ask every client with a GST presence for a list of all first-appeal orders received since July 2017 that are still live in the system.
2. Classify each order as appeal or no-appeal based on merits and quantum. Book a call with the client to confirm the decision.
3. Estimate the aggregate pre-deposit requirement across the portfolio. Share the funding timeline with client CFOs so the cash flow is arranged in May.
4. Begin drafting APL-05 grounds of appeal in May so the filing queue in June is manageable. Last-minute filings increase the risk of data entry mistakes and portal congestion.
5. Mark June 15, 2026 as an internal deadline. Reserve the final two weeks for queries, corrections, and contingencies.

Bottom Line

Notification S.O. 4220(E) is a transitional lifeline, not an indefinite invitation. Every CA who has clients with pre-April 1, 2026 GST appeal orders should be running a portfolio audit this week. The GSTAT will see peak filings in the final ten days of June 2026. The practices that move first will get clean filings in, and the practices that wait will spend the last week firefighting portal timeouts and cash-flow crunches.
