Under India’s central GST framework, an audit examines records and compliance, an assessment determines tax payable, and a show-cause notice (SCN) asks you to answer a proposed action or liability. They are different legal steps, although an audit or assessment issue can lead to a later notice and order. An audit finding or SCN is not automatically a final demand.
This guide explains the distinctions under the Central Goods and Services Tax Act, 2017 (CGST Act). State and Union Territory GST laws form part of the wider framework, so check the law and officer identified in your actual communication. The section cited and the tax period matter, particularly when deciding which determination route applies.

What is the difference between a GST audit and assessment?
| Feature | Audit | Assessment | Show-cause notice |
|---|---|---|---|
| Main purpose | Examine records and test whether declared turnover, tax, refunds, input tax credit (ITC), and other requirements are in order. | Determine tax payable, through self-assessment or a statutory officer-led route. | Give the recipient an opportunity to answer proposed grounds or liability. |
| CGST Act provisions | Sections 65 (tax-authority audit) and 66 (special audit). | Sections 59–64 cover self-assessment and several assessment procedures. Other provisions govern tax determination in context. | Sections 73, 74, and 74A provide notice-based tax determination routes in relevant cases. |
| Typical result | Audit findings communicated to the registered person; further proceedings may follow if the law permits. | An assessment or determination order, or another procedural outcome depending on the route. | A communication setting out proposed grounds or amount and asking for a reply—not, by itself, the final order. |
| Who acts | A tax officer for a section 65 audit; a nominated chartered accountant or cost accountant for a section 66 special audit. | The registered person for self-assessment, or the proper officer under the applicable officer-led route. | The proper officer under the provision cited in the notice. |
| What to look for | Audit period, statutory authority, records requested, observations, and findings. | Section, tax period, calculation, and type of assessment. | Section, allegations, proposed computation, reply date, issuing officer, and service details. |
The table summarizes the CGST Act and its rules. A particular document’s wording and cited provision control how to understand that communication.

What does a GST audit mean?
The CGST Act defines an audit as an examination of records, returns, and other documents to verify declared turnover, taxes paid, refunds claimed, ITC availed, and compliance with the Act and its rules. Under section 65, an authorised tax officer can conduct an audit at the registered person’s place of business or at the officer’s office.
Section 65 audit: notice, timing, and findings
Section 65 provides for at least 15 working days’ advance notice. It provides for the audit to be completed within three months from commencement, with a reasoned extension of up to a further six months. Within 30 days of the audit’s conclusion, the proper officer must inform the registered person of the findings, rights and obligations, and reasons for the findings. These are statutory periods stated in section 65; check the current Act and the actual notice for the wording and how the period applies to a particular case.
The rules identify FORM GST ADT-01 for notice of a section 65 audit and FORM GST ADT-02 for communicating findings. The rules describe the audit period as a financial year or multiples of a financial year. During the audit, the officer may examine books and supporting documents, returns, turnover, exemptions and deductions, tax rates, ITC, refunds, and other relevant matters. The registered person may respond to discrepancies before the officer finalises findings.
Section 66 special audit
A special audit is distinct from the ordinary tax-authority audit under section 65. Under section 66, the relevant officer may direct a registered person to have specified records examined by a nominated chartered accountant or cost accountant in the circumstances set out in that provision. Check whether a communication invokes section 65 or section 66 rather than treating every request for an audit as the same procedure.

What does assessment mean under GST?
“Assessment” is broader than an audit. The Act includes both the registered person’s own calculation and several officer-led procedures; it does not mean that a tax officer has audited the business or that an SCN has already resulted in a demand.
- Self-assessment (section 59): A registered person assesses the tax payable and furnishes returns. Section 59 states that every registered person must self-assess taxes payable under the Act and furnish a return for each tax period as specified under section 39.
- Provisional assessment (section 60): A taxable person may seek a provisional assessment when unable to determine the value of a supply or the applicable tax rate.
- Scrutiny of returns (section 61): The proper officer scrutinises returns for discrepancies. The rules identify FORM GST ASMT-10 for communicating discrepancies and forms for the taxpayer’s explanation and the officer’s response. If the explanation resolves the issue, the officer informs the taxpayer; unresolved issues may lead to further action under the Act.
- Assessment of non-filers (section 62): The rules identify FORM GST ASMT-13 for an order concerning a registered person who has not furnished a return, subject to the conditions in the Act and rules.
- Assessment of unregistered persons (section 63): The rules identify FORM GST ASMT-14 for notice and FORM GST ASMT-15 for an order after the prescribed opportunity to reply.
- Summary assessment (section 64): This is for specified urgent circumstances; the rules identify FORM GST ASMT-16 for the order.
These form names are procedural signposts, not a substitute for checking the current rules or the communication you received. The form, provision, tax period, and facts determine what step is being taken.
Is a GST audit the same as a show-cause notice?
No. An audit is an examination; an SCN is a request to explain why a proposed action or liability should not follow. An audit can uncover an issue that leads to further proceedings, but not every audit results in an SCN, and an SCN does not necessarily follow an audit.
For example, if an audit identifies tax allegedly short paid or ITC allegedly wrongly availed or utilised, section 65(7) allows the proper officer to initiate action under the applicable tax-determination provision. That possibility does not turn the audit findings into a final demand: the findings, any later notice, and any resulting order are separate procedural steps.

An SCN tells the recipient what action or liability the officer proposes and gives an opportunity to respond before a decision is made. For tax determination, sections 73 and 74 direct the proper officer to serve a notice requiring the person to show cause why the specified tax, interest, and applicable penalty should not be paid. The notice and the order that may follow it are different documents.
Sections 73, 74, and 74A
- Section 73 concerns relevant cases other than those involving fraud, wilful misstatement, or suppression to evade tax.
- Section 74 concerns cases involving fraud, wilful misstatement, or suppression to evade tax.
- Section 74A provides another tax-determination route for tax not paid or short paid, erroneous refunds, or wrongly availed or utilised ITC, with consequences that differ according to the circumstances, including whether fraud or similar conduct is involved.
Do not assume every case falls under section 73 or 74. Which provision applies can depend on the tax period and amendments in force. The CBIC-hosted Act text includes section 74A; for a live matter, check the current Act and applicable notifications or circulars as well as the section printed on the notice. No universal reply deadline can be stated without identifying the applicable provision and facts.
What should I check first when I receive a GST notice?
Start by identifying exactly what the communication is and what response it calls for. Record the following before deciding what to do next:
- Document and provision: Is it an audit communication, a scrutiny discrepancy, an SCN, or an order? Note the form number and every section cited.
- Tax period: Record the period involved. It can affect which statutory route and amendments apply.
- Grounds and computation: Identify the alleged facts, proposed tax, interest or penalty, and the basis for the calculation.
- Response date and service: Note the stated reply date, how and when the communication was served, and any instructions for filing a response.
- Issuing authority and records requested: Identify the officer and the legal authority relied on; for an audit, note the period and documents requested.
These checks help distinguish an information or audit step from a proposed liability and a final order. They do not establish whether a particular communication is valid, within time, or correctly calculated; those questions depend on its facts, service, tax period, and the law applicable to that proceeding.
How do the steps fit together?
A scrutiny explanation may resolve a discrepancy, or unresolved issues may lead to further action. A section 65 audit ends with findings communicated to the registered person; if it detects specified tax or credit issues, the officer may initiate the applicable determination process. Where sections 73, 74, or 74A apply, an SCN invites a response before an order is made through the relevant route. The sequence is conditional: an audit, an assessment procedure, an SCN, and an order are not interchangeable names for one event.
The primary references for these distinctions are the CGST Act and the CBIC-published assessment and audit rules. The section 65 procedural wording is also reproduced in CBIC’s “Chapter XIII Audit — CGST Act Updated 1 August 2021”; because that PDF is dated, verify statutory wording against the current Act. The forms and rules can also change, so confirm them against the current rules before relying on a form or procedural detail.
