Section 106 CGST Act — Procedure of Authority and Appellate Authority

How the GST Authority for Advance Ruling and Appellate Authority regulate their procedure — and what finance, tax, legal and business teams should do to prepare for an effective advance-ruling proceeding.

Start here

1. Why Section 106 matters

Section 106 is short, but it is important because an advance-ruling proceeding cannot practically operate without a procedure for receiving documents, hearing parties, considering evidence and completing the matter.

The section gives the Authority for Advance Ruling and the Appellate Authority for Advance Ruling power, subject to the provisions of Chapter XVII, to regulate their own procedure. The power is therefore procedural rather than a licence to decide GST questions outside the jurisdiction or ignore statutory requirements.

Practical message: When your company approaches the AAR or AAAR, do not focus only on the legal question. Build a procedural file: application, facts, evidence, written submissions, hearing preparation, documents produced and final order.

2. Section 106 in simple language

In simple terms, Section 106 says that the Authority and Appellate Authority can manage the way their proceedings are conducted, as long as they remain within the CGST Act and the advance-ruling chapter.

QuestionPractical answer
Can the Authority manage its proceedings?Yes, subject to the Act and Chapter XVII.
Does it have unlimited procedural freedom?No. Its procedure must remain subject to the statutory framework.
Does Section 106 replace Section 105?No. Section 105 separately gives specified civil-court powers for evidence-related functions.
Does Section 106 decide who is bound by a ruling?No. Binding effect is dealt with principally by Section 103.
Does it deal with voiding an advance ruling obtained improperly?No. That is Section 104.

3. What does “regulate its own procedure” mean?

The phrase gives procedural flexibility to the AAR and AAAR. A practical proceeding may require the Authority to determine how submissions are received, how documents are organised, how hearing dates are handled and how parties present their factual and legal positions.

Examples of procedural matters

  • Receiving and arranging written submissions.
  • Considering documents and supporting evidence.
  • Fixing or managing hearing dates within the applicable framework.
  • Calling for clarification where the factual position needs to be understood.
  • Managing the sequence in which the parties present their submissions.
  • Recording and considering material placed before the Authority.
  • Handling procedural communications and directions necessary for the proceeding.
Business lesson: Keep one central procedural tracker for every notice, filing, document request, hearing date, submission and order. This prevents tax, legal and finance teams from working from different versions of the case file.

4. Limits on procedural discretion

Section 106 begins with an important qualification: the Authority or Appellate Authority has this procedural power subject to the provisions of Chapter XVII.

That means a procedural direction cannot be used to override a specific statutory requirement. For example, the Act contains specific provisions dealing with applications, appeals, hearings, binding effect, rectification, voiding of rulings and evidentiary powers.

Organising submissionsJurisdictional limits in the Act

Managing recordsSpecific statutory timelines and conditions

5. Hearings and presenting the case

An advance-ruling case should be prepared for a hearing as a combined fact + law + evidence exercise.

1. IssueState the exact GST question.
2. FactsExplain the transaction as it actually operates.
3. EvidenceSupport important facts with documents.
4. LawExplain why the statutory provisions produce the proposed answer.

Hearing preparation checklist

  • Read the original application from beginning to end.
  • Mark every factual assumption behind the legal conclusion.
  • Keep the executed contract and amendments available.
  • Prepare a one-page transaction flow.
  • Prepare answers to likely factual questions.
  • Identify the person who understands the operational process.
  • Ensure the authorised representative has the latest factual information.

6. Documents and written submissions

A good procedural file should allow the Authority to understand the transaction without repeatedly searching for missing context.

FilePurpose
Issue noteOne-page explanation of the precise GST question.
Factual matrixNeutral description of the transaction and parties.
Contract packAgreement, work order, BOQ, amendments and relevant annexures.
Transaction packRepresentative invoices, ledgers and supporting records.
Legal noteApplicable provisions and reasoning.
Evidence indexMaps each important factual assertion to a document.
Hearing fileQuestions expected, responses, documents and prior submissions.

7. Evidence and the factual matrix

Section 106 should be read alongside Section 105. Section 105 gives specified civil-court powers relating to discovery and inspection, attendance and examination on oath, commissions, and production of books and records. Section 106 then provides the broader procedural framework within which the Authority regulates its procedure.

This makes the factual matrix one of the most important parts of an advance-ruling file.

Fact-to-document mapping

StatementEvidenceOwner
Supplier performs specified activity.Agreement + SOP + sample invoiceOperations
Customer receives specified service.Contract + completion certificateCommercial
Consideration is calculated in a particular manner.Contract + invoices + ledgerFinance
Goods/materials are supplied by a specified party.Purchase records + delivery documentsPurchase

8. Authorised representatives and internal coordination

The person representing the applicant may be a tax professional or legal professional, but the representative should not be expected to invent answers to operational questions.

Before a hearing, hold an internal “fact rehearsal” involving tax, finance, commercial and operations teams.

  • Tax team explains the legal issue.
  • Commercial team explains the contract.
  • Operations explains what happens on the ground.
  • Finance explains billing, accounting and tax treatment.
  • Legal team identifies wording or contractual risks.
The objective is consistency. A legal submission should never describe the transaction one way while the contract, invoice and operational team describe it materially differently.

9. Adjournments and procedural requests

Companies sometimes need additional time because a document is held at a project site, a technical expert is unavailable, or a large set of records needs to be compiled. Any procedural request should be made promptly and professionally, with a clear reason and the exact additional time or action required.

Better approach

  • Do not wait until the last moment to identify missing evidence.
  • Explain why the information is relevant.
  • Identify what has already been prepared.
  • State what remains pending.
  • Give a realistic completion date.
  • Maintain evidence that the request was submitted and tracked.

The Authority's procedural discretion does not mean that every requested extension will automatically be granted. The company should therefore prepare early.

10. Orders, records and communication

Every important procedural step should be recorded internally. This is especially useful when an advance ruling affects tax treatment for several financial periods.

EventInternal record
Application filedApplication copy + acknowledgement + complete annexures
Additional information requestedRequest + response + document index
HearingDate + attendees + hearing notes
Written submissionFinal signed/submitted version
Advance rulingCertified order + internal implementation note
Appeal/rectification/other proceedingSeparate procedural tracker

11. How finance and tax teams should implement Section 106

Section 106 is procedural, but it has a direct impact on internal controls because a successful advance ruling can influence invoicing, GST returns, ITC, accounting and contracts.

FunctionControl
TaxMaintain ruling register and procedural calendar.
FinanceMap ruling conclusions to ledger and invoice treatment.
CommercialNotify tax team of contract changes.
OperationsNotify tax team if actual execution differs from the documented scope.
IT/ERPImplement approved tax codes only after tax sign-off.
ManagementApprove significant tax positions and litigation/advance-ruling strategy.

12. Finance, ERP and GST records

A ruling should not live only in the tax department's email folder. If the ruling affects tax treatment, the conclusion should be translated into an implementation document.

Recommended implementation note

  1. Exact GST question ruled upon.
  2. Important facts on which the ruling depends.
  3. Applicable GST treatment.
  4. Invoice/tax-code configuration.
  5. GSTR-1 and GSTR-3B treatment.
  6. ITC implications, if any.
  7. Contract/project scope covered.
  8. Conditions and limitations.
  9. Events that require re-review.
Important: Section 103 says an advance ruling is binding subject to the statutory scope and continues unless the law, facts or circumstances supporting the original ruling change. Therefore, ERP implementation should contain a review trigger for material changes.

13. Practical examples

Example 1 — Missing technical information

A company applies for a ruling on classification of a specialised machine component. The application describes the product generally, but the Authority needs technical specifications to understand the product.

Practical solution: Prepare a technical evidence pack, identify the person who can explain the manufacturing process and ensure the written submission uses the same technical description as the supporting documents.

Example 2 — Contract changed during the proceeding

A taxpayer files an application based on an agreement. Before the hearing, the commercial team signs a substantial amendment.

Practical solution: Escalate the amendment to the tax/legal team immediately. Do not allow the proceeding to continue on an outdated factual matrix without assessing the effect of the amendment.

Example 3 — Multiple GST registrations

A group has several GST registrations and one registration is involved in an advance-ruling proceeding.

Practical solution: Maintain a GSTIN-wise ruling register. Do not copy the ruling into another GSTIN's tax policy without separately checking the legal and factual scope.

Example 4 — New project after the ruling

A contractor receives a favourable ruling for one project and wants to use the same tax treatment on a new project with different contractual terms.

Practical solution: Compare the two factual matrices before applying the ruling. If the facts or circumstances materially differ, obtain a fresh legal assessment.

14. Construction & infrastructure example

Construction and infrastructure businesses often have complex contracts involving principal contractors, subcontractors, material supply, equipment, site services, mobilisation, design and engineering, escalation, variation orders and recoveries.

For such businesses, procedural preparation should include a project-level evidence pack.

Project evidenceWhy it matters
Letter of awardEstablishes the original commercial scope.
Signed agreementDefines contractual obligations.
BOQ/specificationsExplains the actual work and deliverables.
Variation ordersShows later changes to the factual matrix.
Subcontract agreementsExplains the supply chain and responsibilities.
Measurement/certification recordsSupports actual execution.
Invoices and ledgersConnects the project facts to GST treatment.

15. Section 105 and Section 106 — how they work together

SectionMain focusPractical meaning
Section 105Specified civil-court powers.How the Authority can obtain, inspect and examine evidence.
Section 106Procedure.How the Authority regulates the conduct of its proceedings, subject to Chapter XVII.

For a business, the two can be remembered as:

Section 105 = evidentiary powers.
Section 106 = procedural framework.

They should not be treated as isolated provisions. A company responding to a proceeding should be prepared for both the substantive GST question and the procedural/evidentiary requirements.

16. Common mistakes

  1. Treating the application as a legal-only document. The factual matrix is equally important.
  2. Not updating the tax team about contract changes. This can make the original factual description outdated.
  3. Using different descriptions in different documents. Keep product/service descriptions consistent.
  4. Sending a representative who does not know the transaction. Prepare the right people in advance.
  5. Keeping evidence across disconnected folders. Create a central case file.
  6. Failing to record procedural communications. Maintain a chronology and responsibility tracker.
  7. Implementing the ruling without documenting its assumptions. The business needs to know when the ruling must be re-reviewed.

17. Practical Section 106 workflow

1. DefineWrite the exact GST question.
2. Map factsDescribe the actual transaction.
3. Build evidenceConnect facts to documents.
4. Prepare submissionAlign facts and legal reasoning.
5. Track procedureMaintain dates, requests and filings.
6. Prepare hearingCoordinate tax, legal, finance and operations.
7. Record orderPreserve the complete certified ruling.
8. ImplementUpdate ERP, invoices, returns and SOPs.

20. Frequently Asked Questions

What is the main purpose of Section 106?

It allows the Authority or Appellate Authority, subject to Chapter XVII, to regulate its own procedure. The provision provides procedural flexibility for conducting advance-ruling proceedings.

Does Section 106 give unlimited powers to the AAR?

No. The power is expressly subject to the provisions of the chapter. Specific statutory requirements and limitations continue to apply.

Is Section 106 the same as Section 105?

No. Section 105 deals with specified civil-court powers for discovery, inspection, attendance, examination on oath, commissions and production of books and records. Section 106 deals with regulation of procedure.

Can the Authority ignore the CGST Act while regulating its procedure?

No. Section 106 itself makes the procedural power subject to the provisions of Chapter XVII.

Why should finance teams care about a procedural section?

Because advance-ruling cases depend heavily on facts and records. Finance teams often control ledgers, invoices, reconciliations and GST return evidence that can support or contradict the factual position presented to the Authority.

Should every new project be checked against an old advance ruling?

Yes, where the business proposes to rely on the ruling. Section 103 makes the binding effect dependent on the statutory scope and says the ruling remains binding unless the law, facts or circumstances supporting it change. A new project with materially different facts should therefore be reviewed before the old treatment is adopted.

What is the best internal control for an advance ruling?

Maintain a GST ruling register containing the GSTIN, issue, factual assumptions, covered transactions, ruling date, implementation treatment, supporting documents and triggers requiring re-review.

22. Key takeaways

  • Section 106 gives the AAR and AAAR power to regulate their own procedure, subject to Chapter XVII.
  • It is a procedural provision; it does not itself determine the substantive GST liability.
  • Section 105 and Section 106 work together: Section 105 deals with specified evidentiary powers, while Section 106 provides procedural flexibility.
  • Businesses should maintain a central procedural tracker and a complete evidence file.
  • Finance, tax, legal, commercial and operations teams should agree on one factual matrix.
  • The final advance ruling should be converted into a controlled implementation note covering invoices, returns, ERP and re-review triggers.
