GST Audit in India: Complete Guide to Process, Types & Compliance

Introduction to GST Audit in India

Goods and Services Tax (GST) has transformed India's indirect tax landscape by unifying multiple taxes into a single system. However, ensuring compliance with GST regulations requires businesses to undertake periodic GST audits. A GST audit is a systematic examination of records, returns, and financial statements to verify the accuracy of GST filings and detect any discrepancies.

For businesses operating in India, understanding the intricacies of GST audit requirements, processes, and compliance strategies is critical to avoid penalties and maintain regulatory alignment.

What is GST Audit?

A GST Audit is the verification and examination of a taxpayer’s GST returns, records, and financial data to confirm that GST obligations are accurately fulfilled under the Central Goods and Services Tax Act, 2017 (CGST Act) and corresponding State Acts.

The primary objective of the GST audit is to:

• Ensure the correctness of turnover declared
• Confirm taxes paid and refunds claimed
• Detect input tax credit (ITC) utilization
• Identify compliance gaps or underreporting

Applicability of GST Audit in India

GST audit applicability depends on turnover thresholds and specific conditions:

Note: The mandatory GST audit by Chartered Accountants/Cost Accountants under Section 35(5) has been withdrawn effective from FY 2020-21. However, departmental and special audits continue to apply.
