A GST audit examines a registered business’s records; an assessment or tax-demand process determines liability under a particular provision. An audit finding may lead to further proceedings, but it is not automatically an assessment order. Return scrutiny, a tax-authority audit, a special audit and assessment are separate procedures. Annual return filing and GSTR-9C reconciliation are separate compliance requirements, not audit proceedings.
This guide concerns India’s GST system. If you have received a live notice, check its tax period, form, statutory section, issuing authority and response date. The exact procedure and applicable law depend on those details.

How the four GST procedures differ
The key distinction is what the tax authority is doing: checking a return, examining records, commissioning a specialist examination, or determining tax liability. The same matter can move from one procedure to another, but the steps are not interchangeable.
| Procedure | Who initiates it and why | What the business is asked to do | Notice and timing | Usual result and whether tax is determined |
|---|---|---|---|---|
| Return scrutiny (CGST Act section 61) | The proper officer checks a registered person’s return and related particulars for discrepancies. | Explain the discrepancy and provide supporting information. | The Rules prescribe ASMT-10 for the discrepancy notice and ASMT-11 for the response. The Rules state a response period of no more than 15 days; the Act describes further action for a missing or unsatisfactory explanation by reference to 30 days or a further period allowed. | If the explanation is accepted, no further action is taken on that discrepancy. Otherwise, the officer may take an appropriate further step. Scrutiny itself is not a tax-demand order. CGST Act, section 61; Assessment-Audit Rules. |
| Departmental audit (section 65) | The Commissioner or an officer authorized by general or specific order may audit a registered person. | Provide access, information and assistance so the officer can verify relevant records and matters such as returns, turnover, tax rates, exemptions, input tax credit and refunds. | At least 15 working days’ advance notice is required. The audit ordinarily must be completed within three months of commencement; the Commissioner may extend it by up to six months for recorded reasons. The Rules prescribe ADT-01 for notice and ADT-02 for findings. | The audit produces findings. The taxpayer is to be informed of the findings, rights and obligations, and reasons within 30 days after completion. Further proceedings may follow; the audit does not by itself determine a demand. CGST Act, section 65; Assessment-Audit Rules. |
| Special audit (section 66) | During another proceeding, an Assistant Commissioner or higher officer may invoke this route in the circumstances specified by the Act, with prior approval of the Commissioner. | A Commissioner-nominated chartered accountant or cost accountant examines the specified matter. The taxpayer must have an opportunity to be heard about special-audit material proposed for use against it. | The Rules prescribe ADT-03 for the direction and ADT-04 for findings. The professional’s report is due within 90 days, with a possible further 90-day extension for an application or sufficient reason. | The special-audit report may inform further action, but is not itself a tax-demand order. The Commissioner determines and pays the audit expenses. CGST Act, section 66; Assessment-Audit Rules. |
| Assessment or demand determination | The appropriate statutory route depends on the facts and the conditions in the Act. Routes include provisional assessment, specified best-judgment assessments, summary assessment in limited circumstances, and determination of unpaid or short-paid tax, erroneous refunds or wrongly availed or utilized input tax credit. | Depending on the route, the taxpayer may need to provide information, respond to a show-cause notice, make representations and attend a hearing. | There is no single form or deadline for all assessments. The notice and applicable provision control. Do not use an old general deadline chart to calculate a current response or limitation date. | This is the process that can determine liability and result in an order. The applicable section and procedural rights must be checked for the relevant tax period. CGST Act. |
For a departmental audit, section 65(3) says: “The registered person shall be informed by way of a notice not less than fifteen working days prior to the conduct of audit in such manner as may be prescribed.”

What “GST audit” means—and what it does not mean
Departmental audit
A departmental audit is an examination by an authorized tax officer, which may take place at the business premises or in a tax office. The officer can verify books, supporting documents, returns and other relevant matters. The taxpayer is required to provide access, information and assistance. The notice, scope and period stated in the communication matter: section 65 does not mean every GST-registered business is undergoing an audit.
Special audit
A special audit is a distinct mechanism used during another proceeding, not simply a longer departmental audit. It requires the statutory circumstances, an eligible officer’s opinion, prior Commissioner approval and an auditor nominated by the Commissioner. The taxpayer’s opportunity to address material proposed for use against it is an important procedural safeguard.
What follows an audit
The Rules provide for a response to discrepancies before audit findings are finalized. After the audit concludes, the taxpayer is to receive the findings, rights and obligations, and reasons within the statutory period. If discrepancies are detected, sections 65 and 66 allow further tax action; any demand determination, notice, representation, hearing and order are distinct procedural matters. An audit does not invariably result in tax being found payable.
Assessment is a family of procedures, not a synonym for audit
The CGST Act provides for different forms of assessment, including provisional assessment when a taxpayer cannot determine the value or rate, specified best-judgment assessments for non-filers and unregistered taxable persons, and summary assessment in defined circumstances where delay could adversely affect revenue. Separate demand provisions address matters such as tax not paid or short paid, erroneous refunds, and wrongly availed or utilized input tax credit. Which route applies depends on the facts and the law in force for the relevant period.
For demand proceedings, the Act’s show-cause, representation and hearing requirements are procedural protections, not a substitute for checking the exact notice. Section 75 addresses matters including hearings in specified circumstances and the requirement for an order to state relevant facts and the basis of decision; it also limits an order to the amount and grounds stated in the notice. The CBIC-hosted Act text linked here does not set out a complete current treatment of section 74A or transition rules. Do not rely on older section 73-versus-74 summaries or calculate a limitation period without verifying the operative amendment, commencement notification and rules for the tax period concerned.

GSTR-9 is the annual return; GSTR-9C is a reconciliation statement comparing supplies reported in the annual return with audited annual financial statements. CBIC Circular No. 246/03/2025-GST describes the requirement, effective from 1 August 2021, for registered persons whose aggregate turnover in a financial year exceeds ₹5 crore to furnish a self-certified GSTR-9C with the annual return. That threshold and description do not resolve every taxpayer’s eligibility: check the financial year, taxpayer category, exceptions and notifications that apply. The reconciliation filing is not, by itself, an order for a separate GST audit by a chartered accountant or cost accountant. CBIC Circular No. 246/03/2025-GST; CGST Rules, amended Part A (2022).
What to check when a GST notice arrives
Do not decide what a notice means from its subject line alone. Identify the procedure and the action requested before preparing a response.
- Confirm who issued it. Note the authority, document identification details and GSTIN named in the notice.
- Check the period and legal basis. Record the tax period, statutory section and form number. For example, ASMT-10 concerns return scrutiny; ADT-01 is the prescribed departmental-audit notice. They are not interchangeable.
- Identify what the communication does. Determine whether it seeks an explanation, opens an audit, directs a special audit, proposes a demand or communicates a decision.
- Calendar the response date and method. Follow the deadline and submission instructions in the communication, while checking the governing rule and statute if they appear inconsistent or unclear.
- Reconcile each issue to evidence. Gather the returns, books, invoices, workings and other records relevant to each discrepancy or question; make the response traceable to the figures in the notice.
- Get case-specific advice where needed. A qualified GST practitioner or lawyer can help where tax, interest, penalty, limitation or appeal rights may be involved.
Do not assume that paying an amount, submitting a reconciliation or replying to an audit notice automatically closes the matter. Its legal effect depends on the applicable provision and facts.
