When the Goods and Services Tax Appellate Tribunal (GSTAT) was launched on 24 September 2025 by the Hon'ble Finance Minister, it was hailed as a watershed moment for India's indirect tax ecosystem. GSTAT President Justice (Retd.) Sanjay Kumar Mishra acknowledged the scale of the challenge ahead: the tribunal would have more than 4 lakh cases pending from day one, with approximately 4.83 lakh appeals expected to be filed against orders of the first appellate authority.
The staggered filing schedule, designed to prevent system congestion, was meant to ensure an orderly flow of appeals through to the final deadline of 30 June 2026. The staggering mandate has since been withdrawn with an open invitation to all to file at will.
The Numbers Tell a Different Story
As of --, the GSTAT e-filing portal's own statistics dashboard tells a sobering tale:
Even accounting for the staggered schedule and the fact that many appellants may file closer to the June 2026 deadline, this number is remarkably low. With barely four months remaining, the gap between expectation and reality is too wide to be explained by strategic timing alone.
The question is not whether taxpayers want to appeal -- years of pent-up demand since 2017 confirm they do. The question is: what is preventing them from filing?
Having studied the GSTAT e-Filing Portal User Manual (Version 2.8) and the portal's filing workflow in some detail, the answer lies in a combination of process design, digital accessibility barriers, and a structural gap that particularly affects MSMEs and small taxpayers.
The AR Filing Gap: A Structural Barrier
Perhaps the most significant, and least discussed, issue is that an Authorized Representative (lawyer, CA, or tax practitioner) cannot independently initiate and file an appeal on behalf of a client.
Under the current portal architecture, the appeal filing workflow is anchored to the taxpayer's GSTIN. The login ID is the GSTIN itself. The OTP for authentication is sent to the taxpayer's registered mobile and email. The Authorized Representative can only be added as a representative within an appeal already initiated by the taxpayer.
This stands in stark contrast to the practice before other appellate forums:
For a corporate with a dedicated compliance team, this is a minor inconvenience. For an MSME proprietor in a tier-2 or tier-3 city, who has engaged a professional precisely because they cannot navigate the process themselves, this is a genuine barrier to accessing justice.
The portal does recognise four distinct user types: Taxpayers, Tax Officers, Authorized Representatives, and Legal Practitioners. Advocates get their own registration and credentials. Yet the "Appellant Corner" where appeal filing is initiated is accessible only from the taxpayer login. The AR login has no equivalent independent filing functionality. If the 4,280 registered advocates could file appeals on behalf of their clients, the filing numbers might look very different.
Practical Pain Points for MSMEs and Small Taxpayers
Pre-Deposit Computation
Filing a GSTAT appeal requires a pre-deposit of 20% of the remaining disputed tax under Section 112(8), over and above the 10% already deposited at the first appellate stage under Section 107(6). Computing this correctly requires an understanding of the interplay between these provisions, the demand confirmed in APL-04, and any amounts already admitted or paid. The portal's demand details section has multiple fields for disputed amounts, exemption percentages, and self-calculation corrections. This is not intuitive for a non-professional.
Drafting Grounds of Appeal
The portal recommends downloading an offline Excel utility and pre-filling the grounds of appeal, statement of facts, and relief sought before logging in. While this is sensible advice to avoid session timeouts, it presupposes that the taxpayer can draft legally sound grounds of appeal -- which is substantive legal drafting, not data entry. An MSME owner running a manufacturing unit is unlikely to articulate why the Appellate Authority's interpretation of Section 74 versus Section 73 is erroneous.
Dual-Portal Payment
The appeal filing fee and pre-deposit are paid through Bharatkosh, a separate government payments portal, not within the GSTAT portal itself. For online payment, the user is redirected to Bharatkosh; for offline payment (RTGS/NEFT), the user must independently visit Bharatkosh, make payment, and then upload the challan back on the GSTAT portal. This two-portal navigation adds unnecessary friction.
DSC Requirement
Final submission requires authentication via Digital Signature Certificate (DSC) or Aadhaar-based e-signature. Companies and LLPs must use DSC -- there is no Aadhaar option for non-individual entities. For small businesses that do not already possess a DSC, this represents an additional procurement cost, time delay, and compliance step before they can even file.
Document Digitization
All supporting documents -- the impugned order, APL-04, pre-deposit challans, vakalatnama, affidavits, appeal memo -- must be uploaded as PDFs, with files recommended at under 50 MB and 300 dpi. Many small businesses, particularly in semi-urban and rural areas, lack ready access to scanning infrastructure or the digital literacy to optimize PDF file sizes.
Constructive Suggestions
The GSTAT portal's fundamentals are sound. The GSTIN-based auto-population, offline Excel preparation utility, re-filing mechanism for defect cure, and the structured checklist at the final stage are all well-conceived. The following enhancements could meaningfully close the gap between expectation and reality:
- Enable AR-Initiated Filing: Allow registered Authorised Representatives to initiate appeals on behalf of clients, with taxpayer consent verified via OTP or digital authorisation. This single change, aligning the GSTAT portal with the established practice at CESTAT, ITAT, and the High Courts, could be the most impactful reform in terms of filing volumes.
- Integrate Payment Within the Portal: Bringing Bharatkosh payment fully within the GSTAT filing workflow would reduce drop-offs and simplify the process for less digitally savvy users.
- Build an In-Portal Pre-Deposit Calculator: An automated tool that computes the Section 112(8) pre-deposit based on the demand details and APL-04 data entered would reduce computational errors and eliminate one of the key areas where professional assistance is currently indispensable.
- Expedite Federated Login: The portal's FAQ section mentions a planned federated login with the GSTN portal. Prioritizing this would allow taxpayers to use their existing GST common portal credentials -- a far more familiar authentication environment.
- Consider Simplified Filing for Low-Value Appeals: For appeals below a certain monetary threshold (say, Rs. 10 lakh in disputed tax), a simplified form with fewer mandatory fields and guided prompts could make self-filing genuinely feasible for small taxpayers.
The Bigger Picture
The GSTAT represents a critical milestone in India's GST journey -- the "second floor" of the dispute resolution architecture that has been missing since 2017. The portal's digital-first approach is commendable and aligns with the broader e-governance agenda.
"Digital" is not synonymous with "accessible." The current filing figures suggest that the process, as designed, is working well for professionals and large taxpayers, but not yet for the vast majority of the 4.83 lakh appellants who are waiting in the wings.
With barely four months remaining until the 30 June 2026 deadline, the gap between 4,709 and 4,83,000 deserves serious attention -- not as a criticism of the portal's intent, but as a call to make its promise more fully realizable.
The true measure of GSTAT's success will not be the sophistication of its technology, but whether a small taxpayer in Nashik or Coimbatore can effectively exercise their statutory right of second appeal without being defeated by the process itself.
