1. Why Section 99 matters
Section 98 deals with the original AAR process. Section 99 identifies the authority that handles the appellate stage.
An advance ruling can affect the GST treatment of a transaction, service, product, classification, exemption, valuation or tax liability. If an eligible party is aggrieved by the ruling, the law provides an appellate mechanism.
Section 99 is therefore the bridge between the original AAR ruling and the appellate stage governed by Sections 100 and 101.
2. What people actually search for
3. Section 99 in simple language
Suppose a company asks the Authority for Advance Ruling (AAR) whether a particular service is taxable. The AAR examines the application and gives an advance ruling under Section 98.
If the applicant or an eligible GST officer is aggrieved by that ruling, the GST law provides an appeal mechanism. Section 99 tells us which authority performs the appellate function for that State or Union territory.
The key point is that Section 99 is primarily an authority-identification provision. It does not itself contain the complete appeal procedure.
4. Statutory structure
Section 99 provides, in substance, that subject to the provisions of the advance-ruling chapter, the Appellate Authority for Advance Ruling constituted under the applicable State GST Act or Union Territory GST Act is deemed to be the Appellate Authority for the purposes of the CGST Act in that State or Union territory.
| Provision | Practical role |
|---|---|
| Section 95 | Definitions relating to advance ruling. |
| Section 96 | Authority for Advance Ruling. |
| Section 97 | Application for advance ruling and permitted questions. |
| Section 98 | Procedure followed by AAR and original advance ruling. |
| Section 99 | Identifies the Appellate Authority for Advance Ruling. |
| Section 100 | Appeal to the Appellate Authority. |
| Section 101 | Orders of the Appellate Authority. |
| Section 102 | Rectification of advance ruling. |
| Section 103 | Applicability/binding effect of advance ruling. |
5. Who is the Appellate Authority?
The Appellate Authority for Advance Ruling is the authority constituted under the applicable State Goods and Services Tax Act or Union Territory Goods and Services Tax Act.
For CGST purposes, Section 99 gives that authority the deemed status of the Appellate Authority for the relevant State or Union territory.
This is important because the GST system has a dual structure. Central GST and State/UT GST operate together, and the advance-ruling appellate mechanism is designed around that corresponding framework.
The AAAR constituted under the relevant State GST law performs the appellate function for that State.
The corresponding AAAR constituted under the applicable UT GST law performs the appellate function for that Union territory.
6. Why State/UT GST law matters
Section 99 deliberately refers to an Appellate Authority constituted under a State GST Act or Union Territory GST Act.
Therefore, when studying an actual AAAR proceeding, finance teams should identify the relevant State or UT and examine the corresponding constitution of the authority under that law.
This is also why AAAR orders commonly identify the State/UT authority and may refer to corresponding CGST and SGST/UTGST provisions.
7. AAR vs AAAR
| Point | AAR | AAAR |
|---|---|---|
| Stage | Original advance-ruling stage | Appellate stage |
| Main provision | Section 96/98 | Section 99/101 |
| Purpose | Pronounces the original advance ruling | Deals with appeal/reference arising from the AAR stage |
| Trigger | Application under Section 97 | Appeal under Section 100 or statutory reference |
| Typical question | What is the GST treatment? | Was the AAR ruling correct on the issue appealed? |
8. Section 99 and Section 100
These two provisions should be read together, but they do different jobs.
Identifies the Appellate Authority for Advance Ruling for the relevant State or Union territory.
Provides the statutory route for an eligible person or officer to appeal against an advance ruling.
Section 100 also contains the statutory filing period. Therefore, a taxpayer should not read the 30-day appeal period as if it were contained in Section 99 itself.
9. Who can appeal?
Under Section 100, the concerned officer, jurisdictional officer or applicant aggrieved by an advance ruling pronounced under Section 98(4) may appeal to the Appellate Authority.
| Person | Why an appeal may arise |
|---|---|
| Applicant | The AAR ruling may adversely affect the applicant's proposed or existing GST treatment. |
| Concerned officer | The officer may disagree with the AAR's conclusion. |
| Jurisdictional officer | The jurisdictional tax administration may consider the ruling incorrect and exercise the statutory appeal route. |
This means the appellate mechanism is not exclusively a taxpayer remedy.
10. Appeal timeline
Section 100 generally requires an appeal to be filed within 30 days from the date on which the ruling is communicated to the concerned officer, jurisdictional officer and applicant.
The Appellate Authority may allow a further period of up to 30 days where it is satisfied that sufficient cause prevented the appellant from filing within the original period.
11. What happens at AAAR?
The appellate authority considers the appeal or reference according to the statutory framework. The parties are given an opportunity of being heard before the order is passed.
Section 101 provides that the Appellate Authority may pass an order it thinks fit, including confirming or modifying the ruling appealed against or referred to.
| Stage | Practical activity |
|---|---|
| Appeal filed | Verify form, grounds, fee and supporting documents. |
| Records reviewed | AAAR considers the AAR ruling and relevant appeal material. |
| Hearing | Appellant and relevant parties present their submissions. |
| Decision | AAAR passes the statutory appellate order. |
12. What if AAAR members disagree?
The appellate authority has a specific statutory mechanism for a disagreement between its members.
Where the members differ on the relevant question, the statutory framework deals with the consequence rather than automatically treating one member's view as the final ruling.
For finance teams, the practical lesson is simple: an AAAR proceeding should always be reviewed through the final statutory order and not through an isolated observation or one member's view.
13. Binding effect after AAAR
The fact that a matter reaches AAAR does not mean the resulting ruling becomes a universally binding GST rule for every taxpayer.
Section 103 governs the applicability of an advance ruling and generally connects its binding effect to the applicant who sought it and the concerned or jurisdictional officer in respect of that applicant, subject to the statutory conditions.
14. Practical GST examples
Example 1 — Classification dispute
A manufacturer asks AAR to determine the classification of a specialised product. AAR gives a ruling that the manufacturer believes is incorrect. The applicant can evaluate the appeal route under Section 100, with the relevant AAAR identified under Section 99.
Example 2 — Taxability of a service
A company seeks a ruling on whether a service is taxable. The AAR holds that GST is payable. The company disagrees and considers an appeal within the statutory period.
Example 3 — ITC question
A business seeks an advance ruling on eligibility of ITC for a specific inward supply. If the AAR rejects the position, the applicant can examine the appellate remedy rather than treating the AAR ruling as the end of the process.
Example 4 — Notification benefit
A contractor seeks clarification on whether a particular exemption or concessional notification applies. An adverse AAR ruling can be taken through the prescribed appellate mechanism if the statutory requirements are met.
15. Construction and infrastructure examples
Government works contract
A contractor obtains an AAR ruling on the GST rate applicable to a government project and believes the conclusion is incorrect. The project team should immediately preserve the contract, tender, BOQ, work orders, invoices and the complete AAR order before evaluating an appeal.
HAM project
An infrastructure company asks an advance-ruling question involving a hybrid annuity structure. If the ruling affects valuation or taxability, the appeal team should analyse the exact contractual facts rather than relying on a general industry position.
Mining service
A mining contractor receives an adverse ruling on classification or taxability of a service. The appeal submission should map each activity to the exact question raised before AAR.
Subcontracting
A subcontractor receives a ruling concerning the GST treatment of its services. Before appealing, the finance team should reconcile the AAR facts with actual work orders, invoices and payment terms.
16. Detailed practical cases
Case 1 — Applicant disagrees
The applicant receives an adverse AAR ruling. The first action should be to record the communication date and calculate the Section 100 limitation period.
Case 2 — Officer disagrees
The concerned or jurisdictional officer may also exercise the statutory appeal route. The applicant should therefore monitor the complete appellate status.
Case 3 — Different State ruling
A taxpayer finds an AAAR ruling from another State supporting its position. That ruling may be useful for argument, but the taxpayer should not automatically assume that it is binding on its own State or facts.
Case 4 — Contract changed after ruling
If the commercial arrangement changes materially after an advance ruling, the original ruling should not automatically be assumed to cover the changed facts.
Case 5 — Appeal preparation
The appellant prepares grounds by identifying each finding in the AAR order, the factual assumption behind it and the statutory reason why that finding is disputed.
Case 6 — Hearing preparation
The finance/tax team prepares a concise written chronology, issue-wise arguments and supporting documents before the AAAR hearing.
Case 7 — Ruling implementation
After the final appellate order, the company updates tax configuration, invoice treatment, ITC controls and internal SOPs where the ruling is applicable.
Case 8 — Internal audit review
Internal audit checks whether the implemented GST treatment matches the actual facts and the final applicable ruling.

19. Common mistakes
- Thinking Section 99 itself is the appeal form or limitation provision.
- Confusing AAR with AAAR.
- Missing the Section 100 appeal period.
- Calculating limitation from an incorrect date.
- Appealing without checking the exact facts recorded in the AAR order.
- Using another State's ruling as if it were automatically binding.
- Ignoring the corresponding State/UT GST framework.
- Submitting generic grounds instead of challenging the specific findings.
- Failing to preserve communication/service evidence.
- Implementing an AAR/AAAR ruling beyond the applicant and circumstances to which the statutory binding provisions apply.
20. What Section 99 does not cover
Section 99 is not a general GST appellate provision for every dispute.
| Issue | Section 99? |
|---|---|
| Appeal against an advance ruling | Yes — Section 99 identifies the appellate authority. |
| General GST demand order | No — separate appellate provisions apply. |
| Refund rejection order | No — separate refund appeal framework applies. |
| Registration cancellation dispute | No — separate registration and appeal provisions apply. |
| Every order issued by a GST officer | No. |
21. Current practical relevance
Section 99 remains practically relevant because GST Council records continue to publish AAR and appellate orders. Current appellate records include AAAR matters from multiple States, demonstrating that the advance-ruling appeal mechanism continues to operate in practice.
Recent appellate matters also show why Section 99 should be understood together with Section 100: an AAR ruling is not necessarily the final stage where an eligible party is aggrieved.
