Special Timeline for Backlog / Old GSTAT Appeals: Legal Position, Practical Impact & Filing Strategy

Special Timeline for Backlog / Old GSTAT Appeals: Legal Position, Practical Impact and Filing Strategy

1. Background

This article is intended for taxpayers and other persons who wish to file an appeal before the Goods and Services Tax Appellate Tribunal (“GSTAT”) but have not yet done so due to delay or any other reason. It specifically discusses the relaxation granted by the Government for filing delayed or pending GSTAT appeals, thereby enabling eligible persons to avail the appellate remedy before the Tribunal.

The Goods and Services Tax Appellate Tribunal, commonly known as GSTAT, is the second appellate forum under the GST law. An appeal before GSTAT is generally filed against an order passed by the Appellate Authority under Section 107 or by the Revisional Authority under Section 108 of the Central Goods and Services Tax Act, 2017 (“CGST Act”).

As per Section 112(1) of the CGST Act, 2017, any person aggrieved by such order may file an appeal before the Appellate Tribunal within the prescribed limitation period.

However, for several years after the implementation of GST, the Tribunal was not fully functional. Consequently, many taxpayers who had received adverse orders from the First Appellate Authority or Revisional Authority were unable to effectively pursue their second appellate remedy before GSTAT.

To address this transitional difficulty, the Government has notified a special timeline for filing old or backlog appeals before GSTAT. This relaxation allows eligible persons, whose appeals were delayed due to the non-functionality of the Tribunal or other relevant reasons, to file their appeals within the extended period prescribed by the Government.

I have tried to cover all relevant details in this article. However, if you still have any queries or require further clarification, you may contact me using the details mentioned at the end of this article.

2. Statutory basis: Section 112(1) of the CGST Act

Section 112(1) of the CGST Act, 2017 provides that an aggrieved person may file an appeal before GSTAT against an order passed under Section 107 or Section 108 within three months from the date of communication of the order. The provision also contains an important extension mechanism: the appeal may be filed by the date notified by the Government on the recommendations of the GST Council, whichever is later.

This phrase — “or the date, as may be notified by the Government… whichever is later” — is the statutory foundation for the special backlog timeline. It enables the Government to notify a later date for filing GSTAT appeals where ordinary limitation could not practically operate because the Tribunal was not available.

3. Notification S.O. 4220(E) dated 17.09.2025

The Government issued Gazette Notification S.O. 4220(E) dated 17.09.2025 under Section 112(1) of the CGST Act. The notification provides two separate limitation rules:

The notification specifically states that 30.06.2026 is the notified date up to which appeal may be filed before GSTAT in respect of all cases where the order sought to be appealed against was communicated before 01.04.2026. For orders communicated on or after 01.04.2026, the normal three-month period applies.

4. Why this special timeline was necessary

The special timeline is a transitional relief. GST appeals before the Tribunal remained practically pending because the GSTAT mechanism was not fully operational for a long period. In such circumstances, computing limitation strictly from the date of communication of old appellate orders would have led to serious prejudice to taxpayers, because the statutory appellate forum itself was not effectively available.

Therefore, instead of making every old assessee file condonation applications case-by-case, the Government notified a uniform outer date: 30.06.2026 for all orders communicated before 01.04.2026.

5. Meaning of “order communicated before 01.04.2026”

The cut-off is not based merely on the date of the order; it is based on the date on which the order was communicated to the person filing the appeal.

Therefore, the following distinction is important:

Thus, for deciding whether the special timeline applies, the most important document is the proof of communication / service of the Order-in-Appeal or revision order.

6. Normal limitation and condonation under Section 112

For regular GSTAT appeals, Section 112(1) prescribes a limitation of three months from the date of communication of the order. Section 112(6) empowers GSTAT to admit an appeal within a further period of three months after expiry of the normal limitation period, if sufficient cause is shown.

Accordingly, for orders communicated on or after 01.04.2026, the practical timeline is:

For old / backlog orders communicated before 01.04.2026, the notified date is 30.06.2026. From a conservative compliance perspective, taxpayers should treat 30.06.2026 as the critical statutory deadline and should not wait for any condonation issue to arise.

7. Whether delay after 30.06.2026 can be condoned?

This is an important practical issue. Section 112(6) gives GSTAT power to condone delay for a further period of three months after expiry of the period referred to in Section 112(1). Since the notified date of 30.06.2026 is introduced through Section 112(1), an argument may arise that Section 112(6) can apply even after the notified date.

However, for professional and litigation-risk management, the safer view is that all backlog appeals should be filed on or before 30.06.2026. Any attempt to file after 30.06.2026 may require a separate condonation application and may become a contestable issue before the Tribunal. Therefore, taxpayers should not assume that filing after 30.06.2026 will be automatically accepted.

8. Staggered filing mechanism and its revocation

Initially, GSTAT had introduced a staggered filing mechanism to regulate filing of old appeals in phases. This was done to manage portal load and ensure orderly processing of pending appeals.

However, by Order No. 315/2025 dated 16.12.2025, the President of GSTAT revoked the earlier staggered filing order with effect from 18.12.2025. The order records that, in view of the portal’s capabilities, the staggered filing protocol was dispensed with to promote unhindered access while preserving system efficiency. It also clarified that appeals filed under the earlier staggered mechanism before 18.12.2025 would remain valid.

Therefore, the current practical position is that taxpayers need not wait for any staggered phase. If the case is otherwise eligible, the appeal can be filed on the GSTAT portal, subject to the statutory deadline.

9. Form and manner of filing

Appeal before GSTAT is filed electronically in FORM GST APL-05 under Rule 110 of the CGST Rules, 2017. Rule 110 provides that the appeal must be filed along with relevant documents electronically, and a provisional acknowledgement is issued first. Final acknowledgement with appeal number is issued after removal of defects, if any. The rule also states that the appeal is treated as filed only when final acknowledgement indicating appeal number is issued.

Therefore, merely preparing the appeal or uploading incomplete documents is not enough. The taxpayer should ensure that the appeal reaches the stage of proper acknowledgement and that defects, if any, are removed promptly.

10. Documents to be kept ready for backlog GSTAT appeals

For old GSTAT appeals, the following documents should be compiled immediately:

• Order-in-Appeal passed under Section 107 or revision order under Section 108;
• Original adjudication order / order-in-original;
• Show cause notice and statement / summary of demand;
• Reply filed before adjudicating authority;
• Appeal memo filed before Commissioner (Appeals);
• Written submissions filed before appellate authority;
• Proof of communication of Order-in-Appeal;
• Statement of facts for GSTAT;
• Grounds of appeal before GSTAT;
• Prayer clause;
• Pre-deposit challan / proof;
• Court fee / filing fee proof;
• Authorisation / vakalatnama / letter of authority;
• Reconciliation statements and evidence relied upon;
• Case laws, circulars and notifications relied upon.
• Pre-deposit requirement

Before filing GSTAT appeal, the appellant must comply with Section 112(8). The appellant is required to pay:

• the full admitted amount of tax, interest, fine, fee and penalty; and
• 10% of the remaining disputed tax, in addition to the amount paid at the first appeal stage under Section 107(6), subject to the statutory maximum limit.

In penalty-only matters, where penalty is demanded without demand of tax, the appellant is required to pay 10% of the penalty, in addition to the amount payable at the first appellate stage. Once the pre-deposit under Section 112(8) is made, recovery of the balance amount is deemed to be stayed till disposal of the appeal under Section 112(9).

11. Professional Redraft

In brief, a total pre-deposit of 20% is required for filing an appeal before GSTAT. In case you have any doubt regarding the requirement, calculation, or applicability of pre-deposit, I have already written a detailed article on this subject. You may refer to that article for a comprehensive explanation. The article can be accessed through my author profile, available at the end of this article.

12. Practical importance of filing before 30.06.2026

The date 30.06.2026 should be treated as a strict internal deadline for all old GSTAT matters. Delay may result in serious consequences, including:

• objection on limitation;
• requirement to file condonation application;
• risk of rejection at scrutiny/admission stage;
• continuation of recovery proceedings;
• finality of the adverse appellate order;
• loss of statutory second appellate remedy.

For professional handling, firms should prepare a separate GSTAT backlog tracker containing:

13. Conclusion

Notification S.O. 4220(E) dated 17.09.2025 is a significant transitional measure for GST litigation. It provides a one-time special filing window for old GSTAT appeals where the order sought to be appealed against was communicated before 01.04.2026. Such appeals may be filed up to 30.06.2026. For orders communicated on or after 01.04.2026, the normal limitation of three months from the date of communication applies.

The key takeaway is simple: all backlog GSTAT appeals relating to orders communicated before 01.04.2026 should be identified, documented, drafted and filed before 30.06.2026 without waiting for the last date. This will protect the assessee’s statutory appellate remedy and avoid unnecessary litigation on limitation.
