GST Audit and Assessment explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
The GST enforcement framework involves multiple levels: scrutiny of returns, audit of accounts, and formal assessment proceedings. Understanding each type helps businesses prepare adequately and respond effectively.
Types of GST Audits
Section 65 — Departmental Audit
- Conducted by Commissioner or authorized officer at the taxpayer's business premises
- 15 days advance notice to the registered person
- Duration: 3 months (extendable by 6 months with Commissioner's approval)
- Scope: verification of records, returns, ITC, classification, valuation, output tax
- On completion: audit report prepared; if discrepancies found, demand initiated under Section 73/74
Section 66 — Special Audit
- Ordered when transactions are complex, turnover has not been declared correctly, or ITC appears inflated
- CA or Cost Accountant nominated by Commissioner conducts the audit
- Must be completed within 90 days (extendable by 90 days)

Return Scrutiny (Section 61)
GST officers scrutinize returns and compare with other data (GSTR-1 vs GSTR-3B mismatch, ITC claim vs GSTR-2B, annual return vs monthly returns). If discrepancies found:
- Notice issued to taxpayer for explanation
- Taxpayer must respond within 30 days
- If explanation satisfactory: notice dropped
- If unsatisfactory: proceedings under Section 73/74 initiated
