For businesses that have been navigating GST disputes since 2017 without a functional second appellate forum, the operationalisation of GSTAT on 24 September 2025 is a landmark opportunity-and an urgent deadline. Over 4 lakh orders from First Appellate Authorities have accumulated, and all backlog appeals must be filed by 30 June 2026. Missing this deadline means permanent loss of the right to challenge the order before the Tribunal.
This blog provides the complete timeline from receiving the first appellate order to the GSTAT’s final order-with every government portal step mapped to a calendar. Whether you’re a business filing your first GSTAT appeal or a professional advising clients on GSTAT appeal filing services (know more), this timeline ensures you don’t miss a single step or deadline.

Two Timelines: Backlog vs Normal Appeals
| Parameter | Backlog Appeals (Pre-1 April 2026 Orders) | Normal Appeals (Post-1 April 2026 Orders) |
|---|---|---|
| Order communication | Before 1 April 2026 | On or after 1 April 2026 |
| Filing deadline | 30 June 2026 (absolute outer limit) | 3 months from date of order communication |
| Delay condonation | Not applicable-30 June 2026 is the hard cut-off | Up to 3 additional months at Tribunal’s discretion (Section 112(6)) |
| Filing window | Open since 24 Sept 2025. Staggered restriction lifted 16 Dec 2025. All backlog appeals can be filed now. | Standard 3-month window from each order |
| Consequence of missing deadline | Permanent loss of right to GSTAT appeal. Only option: High Court writ petition (costlier, limited to questions of law) | Permanent loss unless condonation is granted within the 3-month extension |
CRITICAL DEADLINE: If you received an adverse first appellate order before 1 April 2026 and have not yet filed a GSTAT appeal, you have until 30 June 2026 to file. This deadline will not be extended. For detailed portal steps, see our step-by-step GSTAT appeal guide (know more).
Government Portal Steps: Tab-by-Tab on efiling.gstat.gov.in
Form GST APL-05 on the GSTAT e-filing portal has 6 tabs that must be completed sequentially. Here is the tab-by-tab breakdown:
Tab 1: Order Details
- Select the appellate/revisional order being challenged
- Enter ARN/CRN from the first appeal (APL-01/APL-03)
- If ARN/CRN is not in GSTN system: upload certified copy of order manually
- Verify the order date, authority name, and order number auto-populated from GSTN
Tab 2: Case Details
- Enter case information: type of appeal (assessee or departmental), nature of dispute
- Pro tip: Use the offline Excel template to prepare data, then copy-paste into the portal to avoid data loss from session timeouts
Tab 3: Appellant & Respondent Details
- Appellant details auto-populate from GSTIN registration
- Respondent: the jurisdictional GST officer or Commissioner (Appeals)
- Verify all details match the first appeal records
Tab 4: Add Representative
- Add your legal representative (CA, Advocate, or authorised person)
- Vakalatnama is mandatory if the representative is not the taxpayer
- The representative must be registered on the GSTAT portal first-their name will appear in the dropdown only after registration
Tab 5: Demand Details
- Fill the demand calculation sheet showing: total demand, admitted tax, disputed tax, pre-deposit paid
- If APL-04 is in the system, demand details auto-populate. If not, enter manually
- Ensure the pre-deposit amount under Section 112(8) is actually paid before proceeding
Tab 6: Upload Documents
- Upload all documents in PDF format: detailed appeal with grounds (consecutively numbered), affidavits, impugned order (if manual filing), vakalatnama, pre-deposit proof
- Documents must be paginated, indexed, and bookmarked per GSTAT Procedure Rules
- Translations required if original documents are in a language other than English or Hindi
After completing all 6 tabs, pay the court fee through the Bharatkosh portal (online or offline), digitally sign the form, and submit. You receive an instant provisional acknowledgment via SMS and email. For the complete portal registration walkthrough, see our GSTAT e-filing portal guide (know more).
Pre-Deposit: How to Compute and Pay
| Component | Amount |
|---|---|
| Full admitted tax | 100% of admitted (undisputed) tax must be paid before filing |
| Pre-deposit at First Appeal (Section 107) | 10% of disputed tax (already paid) |
| Additional pre-deposit at GSTAT (Section 112(8)) | 10% of disputed tax (additional) |
| Total effective pre-deposit | 20% of disputed tax (10% + 10%) |
| Cap per enactment | Rs 20 crore each for CGST and SGST (total Rs 40 crore combined) |
| Penalty-only demands | 10% of penalty amount (per 55th GST Council recommendation) |
Payment method: Pay through the GST portal using the Electronic Cash Ledger. Generate challan, make payment via net banking/NEFT/RTGS, and retain the challan reference number for attachment to Form APL-05. The portal validates pre-deposit payment before allowing form submission.
Filing Fee Structure
| Disputed Amount | Fee |
|---|---|
| Up to Rs 5 lakh | Rs 5,000 (minimum) |
| Rs 5 lakh to Rs 25 lakh | Rs 1,000 per Rs 1,00,000 of disputed tax/ITC |
| Above Rs 25 lakh | Rs 25,000 (maximum cap) |
| Appeals without tax/penalty demand | Flat Rs 5,000 |
Fees are paid through the Bharatkosh payment gateway integrated into the GSTAT portal. Both online (net banking, UPI, card) and offline (challan at designated bank) modes are available.
After Filing: What Happens Next
- Registry scrutiny (7-15 days). The GSTAT registry reviews the filed appeal for completeness. If defects are found (missing documents, incorrect demand details, unsigned vakalatnama), a deficiency memo is issued. You have 7 days to cure defects.
- Final acknowledgment. Once scrutiny is cleared, the appeal number is assigned in Part B of Form GST APL-02A. This is the official filing date for limitation purposes.
- Admission and cause list. The Tribunal admits the appeal and assigns it to a Bench. Hearing dates are published on the GSTAT portal’s daily cause list. For businesses managing income tax return filing (know more) alongside GST disputes, tracking both IT and GST appellate timelines is critical.
- Hearing process. Under Rules 41-52 of the GSTAT Procedure Rules: appellant is heard first, respondent next, rejoinder allowed. The Tribunal may admit additional evidence (Rule 46) if not produced before the first appellate authority for sufficient cause. Adjournments are granted at the Tribunal’s discretion.
- Order within 30 days. The Tribunal must pronounce its order within 30 days from the date of the final hearing. A summary is uploaded on the GSTAT portal, and certified copies are provided to both parties.
- Rectification. The Tribunal may rectify any error apparent on the face of the record within 3 months of the order, after hearing both parties.
- Implementation. The jurisdictional officer must implement the order: adjust tax, ITC, or penalty in the taxpayer’s electronic liability register. If the order is in the taxpayer’s favour, the pre-deposit is refundable with interest.
Common Mistakes That Lead to Rejection
Mistake 1: Missing the 30 June 2026 deadline for backlog appeals. This is the most consequential mistake. Once this deadline passes, there is no remedy-no condonation, no restoration. The only option is a High Court writ petition, which is limited to questions of law and significantly more expensive.
Mistake 2: Underpaying the pre-deposit. The total pre-deposit is 20% of disputed tax (10% at first appeal + 10% at GSTAT). Many appellants compute only 10% and forget the cumulative requirement. The portal validates payment-underpayment blocks filing.
Mistake 3: Filing a combined appeal for multiple orders. If the first appellate order covers multiple orders-in-original, each requires a separate Form GST APL-05. Combined filing is rejected at scrutiny.
Mistake 4: Not registering the representative on the GSTAT portal before filing. If your CA or Advocate is not registered on efiling.gstat.gov.in, their name will not appear in the Add Representative dropdown. Register them first, then file the appeal.
Mistake 5: Uploading documents without pagination, indexing, or bookmarking. The GSTAT Procedure Rules require documents to be paginated, indexed, and bookmarked. Uploading a single unstructured PDF leads to a deficiency memo and delays.
Key Takeaways
The GSTAT appeal filing process is a structured, end-to-end digital workflow governed by Section 112 of the CGST Act and the GSTAT (Procedure) Rules, 2025. The timeline from receiving the first appellate order to the Tribunal’s final order spans 6-18 months, depending on case complexity and Bench workload.
For backlog appeals (orders before 1 April 2026), the absolute outer deadline is 30 June 2026-missing this date means permanent loss of the right to appeal. Normal appeals (post-1 April 2026) have a standard 3-month limitation with discretionary condonation of up to 3 additional months. The pre-deposit is 20% of disputed tax (capped at Rs 20 crore per enactment), and the filing fee is Rs 1,000 per Rs 1 lakh (capped at Rs 25,000).
All filing is through efiling.gstat.gov.in using Form GST APL-05 with 6 tabs (Order, Case, Parties, Representative, Demand, Documents). Fee payment is through Bharatkosh. Registry scrutiny, defect cure, admission, hearing, and order follow a prescribed sequence. For businesses with GST disputes pending since 2017, this is the most critical compliance window-and professional assistance ensures no deadline is missed and no filing defect blocks admission.
Don’t Miss the 30 June 2026 Deadline
If you have received adverse orders from GST First Appellate Authorities and have not yet filed your GSTAT appeal, time is running out. The 30 June 2026 deadline for backlog appeals is absolute-no extensions, no condonation. Every day of delay is a day closer to permanent loss of your appeal rights.
