GST investigation and GST adjudication are different stages. Investigation is the evidence-gathering phase: authorised officers may seek records, summon people, inspect premises, search, seize documents or goods, and, in specified cases, obtain arrest authorisation. Adjudication is the decision phase: after a statutory notice and an opportunity to respond, the proper officer determines tax and related consequences in a reasoned order. A summons, search, or payment made during an investigation is not itself an adjudication order.
This guide applies to India’s GST framework. The CBIC Act page used here contains older wording for sections 73 and 74, and it does not settle the current consolidated text or financial-year application of section 74A. Confirm the operative provision, limitation period, and amendments for the relevant tax period before relying on any deadline.

Investigation and adjudication at a glance
The two terms describe separate functions, even when the same dispute eventually moves from one to the other. The following comparison is a practical overview, not a complete procedure for every type of proceeding.
| Issue | GST investigation | GST adjudication |
|---|---|---|
| Purpose | Collect information, evidence, documents, or statements and examine possible non-compliance under statutory inquiry and enforcement powers. | Determine tax liability and related consequences through the statutory demand process. |
| Typical actions | Inspection, search, seizure, summons, and—in specified circumstances—arrest authorisation. | Show-cause notice, written response, hearing where applicable, consideration of evidence, and a reasoned order. |
| Main legal material | Sections 67, 69, and 70 of the Central Goods and Services Tax Act, 2017, together with CBIC instructions on summons and deposits. | Demand provisions in sections 73–75 as displayed on the retrieved CBIC page, section 107 for an appeal, and officer-assignment circulars. |
| Safeguards or remedy | Statutory conditions and authorisations, plus CBIC administrative safeguards for summons and enforcement deposits. | Notice and hearing protections and an appeal route, subject to the current limitation period and applicable statutory section. |
The CBIC Central GST Act page, Instruction 03/2022-23, and Instruction 01/2022-23 provide the statutory and administrative material behind this distinction.

What a GST investigation does
An investigation asks what happened and gathers material that may support, weaken, or clarify a tax allegation. It is not the final determination of liability. The CGST Act gives officers specific powers, each with its own statutory threshold; those powers are not a general licence to demand anything without reference to the Act.
Inspection, search, and seizure under section 67
Section 67 addresses inspection, search, and seizure in specified circumstances. The authority is linked to a proper officer not below the rank of Joint Commissioner who has reasons to believe that the statutory conditions exist. The wording matters: an investigation must be tied to the conditions in the provision and to the required authorisation, rather than described as an unrestricted power.
During an authorised action, officers may examine premises, records, goods, or other relevant material within the scope of the statutory order. Keep a contemporaneous inventory of documents and devices handed over, note what is copied or taken, and obtain the paperwork provided by the officers. Those practical steps preserve an accurate record; they do not replace the statutory safeguards or any remedy available under the Act.

Arrest authorisation under section 69
Section 69 concerns arrest authorisation by the Commissioner for specified offences. It is distinct from an ordinary information request or summons. The existence of an investigation does not by itself mean that arrest is authorised; the statutory conditions and the Commissioner’s role must be considered in the particular case.
Summons under section 70
Section 70 empowers a proper officer to summon a person whose attendance is considered necessary to give evidence or produce documents or other things. For the purposes specified in the section, the inquiry is treated as a judicial proceeding. A summons is therefore a formal statutory step, not merely an informal invitation, but it remains limited by the purpose and conditions of the provision.
Read the summons carefully. Identify the issuing officer, date, place, subject matter, and documents requested. Preserve the original notice and prepare a document index. If a request is unclear, seek clarification in writing and obtain professional advice promptly rather than ignoring it. Keep copies of everything supplied and a note of attendance and questions asked.
CBIC safeguards for issuing summons
CBIC Instruction 03/2022-23, issued by the GST-Investigation Wing on 17 August 2022, is an administrative instruction. It does not amend section 70, but it directs officers on how the power should be exercised and documented.

Judicious use and alternatives
The instruction encourages officers to consider a letter requisition where that would obtain the required information without compelling attendance. It states:
“While issuing of summons is one of the instruments with the Department to get/obtain information or documents or statement from any person to find out the evasion of the tax etc., however, it needs to be ensured that exercise of such power is done judiciously and with due consideration.”
The quotation is an institutional statement in the CBIC instruction; it is not attributed to a named individual. The full instruction is available at CBIC Instruction 03/2022-23.
Internal permission and recorded reasons
Under the instruction, Superintendents generally issue summons after obtaining prior written permission from an officer not below the rank of Deputy or Assistant Commissioner. Reasons for issuing the summons should be recorded. For operational reasons, oral or telephonic permission may be used, but it should be reduced to writing and reported promptly.

Attendance or non-attendance and the statement made should be recorded in the investigation file. Summons should normally identify whether the person is being called as an accused, co-accused, or witness, unless disclosing that status could harm the investigation. These are internal safeguards and documentation requirements; the underlying statutory authority remains section 70.
If you receive a summons
- Verify that it identifies the issuing office, date, place, and the information or documents sought.
- Preserve the notice and set a written response and attendance plan before the stated date.
- Collect relevant ledgers, invoices, returns, contracts, correspondence, and electronic records without altering originals.
- Ask the issuing office in writing about an ambiguous or disproportionate request; keep proof of the communication.
- Attend or seek a formally recorded rescheduling where necessary. Do not simply disregard the summons.
- Maintain your own attendance note and retain copies of documents submitted and statements signed.
These steps are practical record-keeping precautions, not a substitute for advice on the facts of a particular investigation.
Searches, seizures, and payments during enforcement activity
What a search does—and does not—decide
A search or seizure helps officers obtain evidence. It does not by itself fix the amount of tax payable, establish intent, or replace the later notice-and-order process. Treat the search record, inventories, statements, and seized material as evidence that may be considered in a subsequent proceeding.
Deposits and DRC-03
CBIC Instruction 01/2022-23, dated 25 May 2022, addresses deposits made during search, inspection, or investigation. It records concerns raised by some taxpayers about force or coercion and describes the option of making a voluntary payment through Form DRC-03. The instruction is available at CBIC Instruction 01/2022-23.

Do not assume that every payment was coerced, and do not assume that every payment was freely made merely because DRC-03 was used. Most importantly, a deposit is not itself a final adjudication. Liability still depends on the applicable law, evidence, statutory notice, and order.
What GST adjudication does
Adjudication is the reasoned decision stage. The proper officer considers the department’s case, the taxpayer’s response, the evidence, and the statutory provisions before determining whether tax and related consequences are payable.
Notice before determination
The demand provisions contemplate service of a show-cause notice. The notice should identify the proposed liability and the basis on which the department seeks to recover it. A taxpayer should respond to each allegation, challenge unsupported calculations, identify documents already supplied during investigation, and provide any legal or factual explanation relevant to the proposed demand.
Response, hearing, and reasoned order
Adjudication is more than accepting an investigation report or converting a deposit into a demand. The authority must consider the material before it and issue a reasoned decision under the applicable provision. Keep proof of filing, request a hearing where the procedure provides for one, and check that the final order addresses the submissions and calculations actually made.
Sections 73, 74, and 74A: verify the operative law
The retrieved CBIC Act page displays legacy wording for sections 73 and 74. It does not resolve the current consolidated wording or the effective financial-year application of section 74A. Consequently, do not use an old explanation to decide whether a case falls under a particular demand section, what limitation applies, or which penalty formula is current. Confirm the amended Act, relevant notifications, and the tax period before filing a response or calculating exposure.
Section 75 contains general provisions connected with determination, but the exact effect of any subsection depends on the current text and the facts. A professional reviewing the notice should map each allegation to the provision in force for the relevant period rather than rely on a section number alone.
Rank #4
Who investigates and who adjudicates?
Organisational responsibility is not a universal rule that the officer who investigates must decide the demand. CBIC Circular 31/05/2018-GST assigned proper officers for sections 73 and 74, and Circular 169/01/2022-GST amended that assignment framework. The circulars show why the designation and jurisdiction in a notice matter. They should be read with the current assignment orders, not treated as a blanket statement about every case.
For show-cause notices issued by the Directorate General of GST Intelligence and assigned to a Common Adjudicating Authority, Circular 250/07/2025-GST discusses the related review, revision, and appeal structure. The circular, dated 24 June 2025, is available at Circular 250/07/2025-GST. The earlier assignment material is at Circular 31/05/2018-GST and Circular 169/01/2022-GST.
When reviewing a notice, check the issuing formation, the named adjudicating authority, the provision invoked, the tax period, and the document describing the authority’s assignment. If jurisdiction or assignment is disputed, raise it in the prescribed response and obtain advice on the appropriate procedural remedy.
How the two stages connect
- Information or suspected non-compliance arises. The department may begin an inquiry using the statutory powers available for that situation.
- Evidence is collected. Officers may seek records or statements by summons and, where statutory conditions and authorisation exist, inspect, search, or seize. Arrest authorisation is a separate power under section 69 for specified offences.
- The department evaluates the material. A deposit or statement may be part of the record, but neither automatically determines liability.
- A show-cause notice is issued if a demand is proposed. The notice should state the basis and amount claimed under the applicable provision.
- The taxpayer responds. Address facts, calculations, documents, limitation, jurisdiction, and the statutory section in force for the relevant period.
- The proper officer adjudicates. The authority considers the submissions and issues a reasoned order.
- Review or appeal may follow. The available route and time limit depend on the order, current law, and any applicable assignment arrangement.
An investigation can therefore lead to adjudication, but the phases have different purposes and safeguards. A summons is not a show-cause notice; a search report is not an adjudication order; and a DRC-03 deposit is not, by itself, a final determination.
Appealing an adjudication order
Section 107 provides an appeal to the Appellate Authority for a person aggrieved by a decision or order of an adjudicating authority. The CBIC Act page used for this explanation states a three-month period from communication of the order. Because that page may be stale and limitation can be affected by amendments, exclusions, extensions, and case-specific facts, verify the current operative period immediately after receiving an order.
Appeal preparation checklist
- Record the date and method of communication of the order.
- Obtain the complete order, annexures, relied-upon documents, and calculation sheets.
- Separate factual grounds from legal grounds and identify every finding challenged.
- Reconcile amounts already paid or deposited with the demand and explain the treatment sought.
- Check the current pre-deposit, form, filing location, limitation, and stay requirements before filing.
- Preserve proof of filing and monitor any request for additional information or hearing.
For orders involving a Common Adjudicating Authority in the DGGI context, read the review, revision, and appeal arrangements in CBIC Circular 250/07/2025-GST alongside the current statute and the order itself.

During investigation
- Ask which statutory power is being used and keep the written authorisation or summons.
- Preserve originals and create a disclosure log for every document, device, or statement supplied.
- Read statements carefully before signing and request correction of factual errors.
- Record amounts paid, the stated purpose, and the acknowledgement received.
- Escalate concerns about coercion, unclear requests, or missing records promptly through the appropriate legal channel.
During adjudication
- Check that the notice names the correct taxpayer, period, provision, and authority.
- Answer the notice within the stated period and retain filing proof.
- Challenge calculations with a reconciliation that can be checked invoice by invoice or return by return.
- Address evidence obtained during investigation rather than assuming the adjudicator will infer your position.
- Read the final order for reasons, findings on submissions, and the stated appeal route.
These safeguards improve the record. They do not guarantee a particular outcome and should be adapted to the facts and the current procedural rules.

Common misunderstandings
“A summons means the tax has already been decided.”
No. A summons seeks attendance, evidence, or documents under section 70. A tax decision belongs to the adjudication stage after notice and consideration of the response.
“If I pay during a search, the case is over.”
No. CBIC’s deposit instruction recognises DRC-03 payments during enforcement activity, but a deposit does not itself constitute a final adjudication. The legal basis and treatment of the amount must still be examined.
“Every investigation officer can issue the final order.”
No universal rule says that. Officer assignments have been set and amended through CBIC circulars, and particular DGGI notices may be assigned to a Common Adjudicating Authority.
Recommended Free Tools
“The three-month appeal period printed on an old webpage is always current.”
Not necessarily. The retrieved Act page states three months, but the page contains legacy wording and current amendments or case-specific rules may affect limitation. Verify the operative law when the order is communicated.
“Section 73 or 74 can be selected without checking the tax year.”
No. The current consolidated provisions, including the effective application of section 74A, must be checked for the relevant financial year before assessing demand, penalty, or limitation.
What to do when a notice or order arrives
- Calendar every date. Note receipt, response, hearing, payment, and appeal dates separately.
- Build the record. Assemble returns, ledgers, invoices, contracts, correspondence, investigation statements, inventories, payment acknowledgements, and prior submissions.
- Map the allegations. Create a table matching each proposed demand to the tax period, transaction, document, statutory provision, and amount.
- Check the law in force. Verify amendments and financial-year application, especially where sections 73, 74, or 74A are involved.
- Respond in a traceable way. File through the prescribed channel, retain the acknowledgement, and keep an indexed copy of the complete submission.
- Decide on review or appeal promptly. Do not wait for informal assurances if an order has been communicated; obtain advice on limitation and any required pre-deposit.
Because GST procedure and assignments can change, a tax professional should review a live summons, search record, show-cause notice, or adjudication order before you choose a response strategy.
Bottom line
Investigation is the statutory evidence-gathering phase; adjudication is the notice-and-decision phase. Sections 67, 69, and 70 give conditional investigation powers, while the demand provisions require a separate determination process. CBIC’s summons and deposit instructions add administrative safeguards, but they do not convert an investigation action into a final tax order. When an order arrives, verify the current section, tax period, authority assignment, and appeal limitation before acting.
