What is GST Audit & Assessment?
GST Audit and Assessment are the legal procedures used to verify the accuracy of a taxpayer’s self-declared liabilities. Assessment is the initial process of determining tax liability, whereas an Audit involves a detailed examination of records, returns, and other documents maintained by the business. The goal is to ensure that the turnover declared is correct, taxes paid are accurate, and Input Tax Credit (ITC) claimed is legitimate. In 2026, the department utilizes advanced data analytics to compare your GST filings with income tax records and e-way bill data to identify potential revenue leakages.
Who Must Undergo Audit & Assessment?
Compliance requirements are divided into mandatory obligations and elective or department-driven procedures:
1. Mandatory Compliance (Statutory)
Threshold-Based Reconciliation: Any registered taxpayer whose aggregate turnover exceeds the prescribed limit in a financial year is mandated to file a self-certified reconciliation statement (GSTR-9C).
Specific Business Structures: Large-scale manufacturers, multi-state service providers, and entities with complex inter-branch transfers often fall under mandatory annual review due to their turnover volume.
2. Voluntary & Departmental Categories
Self-Assessment: This is the primary obligation for every registered business. It involves voluntarily calculating tax liability and filing monthly/quarterly returns.
Departmental Audit (Section 65): This is not based on turnover but on “Risk Parameters.” The Commissioner may order an audit of any business—large or small—if their data shows inconsistencies or high-risk ITC patterns.
Special Audit (Section 66): During any stage of scrutiny or investigation, if a tax officer believes the complexity of the case warrants it, they can mandate a Special Audit to be conducted by a nominated Chartered Accountant.
Best Judgment Assessment: This is a forced assessment triggered when a business fails to file returns or register despite being liable, allowing the officer to determine tax based on available data.
Steps in the process of GST Audit & Assessment
- Receipt of Form GST ADT-01, providing the taxpayer at least 15 days to prepare for a departmental audit.
- The audit team examines the trial balance, ledgers, and reconciliation statements to check for tax short-payments.
- The auditor shares a summary of discrepancies, allowing the business to provide clarifications or pay dues voluntarily.
- The process concludes with the issuance of Form GST ADT-02, detailing the final observations and any legal actions required.
Note
Consistency is your best defense. Ensure that your GST filings are perfectly synchronized with your Income Tax Audit reports. Discrepancies between these two platforms are the most common trigger for a deep-dive departmental audit.

Frequently Asked Questions
-
Is every business subject to a mandatory GST Audit by the department?
No. Departmental audits are selective and based on computerized risk assessment. However, threshold-based annual reconciliation is mandatory for eligible businesses.
-
What is a “Best Judgment Assessment”?
If a taxpayer fails to file returns, the officer assesses the tax liability based on the “best of their judgment” using available data.
-
How much notice is given before a GST Audit starts?
Taxpayers must be given at least 15 working days’ notice via Form GST ADT-01.
-
Can the department audit a business that has already cancelled its registration?
Yes. The department can audit any period during which the entity was registered, even if the GSTIN is now inactive.
-
What is the time limit for completing a departmental audit?
An audit must generally be completed within 3 months, though it can be extended by an additional 6 months for complex cases.
