GST Department Audit: 2026 Why Does Your Business Get Selected and What Should You Do?

A GST Department Audit is conducted by the GST authorities to verify whether a registered taxpayer has correctly complied with GST law, paid the correct tax and claimed eligible Input Tax Credit (ITC). Selection for audit does not necessarily mean that fraud or tax evasion has occurred. In many cases, businesses are selected based on risk parameters or data analysis.

What is a GST Department Audit?

A departmental audit is conducted under Section 65 of the CGST Act. The department verifies turnover, tax payment, ITC claims and statutory compliance. The audit normally begins with Form GST ADT-01 and concludes with Form GST ADT-02.

Common Reasons for GST Department Audit

• Difference in turnover reported in GST returns and financial records.
• Sudden reduction in turnover.
• Excessive credit notes.
• Mismatch between GSTR-1 and GSTR-3B.
• Invoice mismatches or incorrect reporting.
• Wrong or excess Input Tax Credit (ITC) claimed.
• Selection under GST risk-based scrutiny.

What Should You Do After Receiving an Audit Notice?

Carefully read the notice and prepare all records requested by the department.

• GST Registration details

After Completion of Audit

After verification, the department issues Form GST ADT-02 containing the audit findings. If discrepancies are identified, further proceedings for tax, interest or penalty may be initiated as per law.
