When Does GST Audit Apply?

GST audit is mandatory for taxpayers whose turnover exceeds a specified threshold during a financial year. The audit is conducted by a Chartered Accountant (CA) or a Cost Accountant to verify the correctness of GST returns and records.

• Threshold Limit

The current turnover limit for GST audit is ₹2 crore for most states. If your aggregate turnover in a financial year exceeds this amount, you must get your accounts audited under GST.

• Aggregate Turnover

This includes all taxable supplies, exempt supplies, exports, and interstate supplies made by your business. It covers all branches and units registered under the same PAN.

• Voluntary Audit

Even if your turnover is below the threshold, you can opt for a GST audit voluntarily to ensure compliance and avoid future issues.

What Does the GST Audit Cover?

The GST audit examines various aspects of your business transactions and records to confirm compliance with GST laws:

• Accuracy of turnover declared in GST returns

• Correctness of input tax credit claimed

• Proper classification of goods and services

• Timely payment of GST dues

• Maintenance of prescribed records and documents

• Reconciliation of GST returns with financial statements

  
  

The auditor prepares a report in Form GSTR-9C, which is a reconciliation statement between your audited financials and GST returns.
