What is a Special Audit Under GST?

The Special Audit under GST happens under the supervision of Chartered Accountants (CA) or Cost Accountants (CMA), whom the Commissioner selects to lead the process.

The tax authorities can start a special audit under the provisions of Section 66 of the Central Goods and Services Tax (CGST) Act, 2017.

Key Reasons for Ordering a Special Audit

A special audit is generally triggered by the following red flags:

Discrepancies in input tax credit claims.

Complex financial transactions need deeper investigation.

Significant variation between turnover declared and actual business activity.

Repeated default or non-compliance with GST provisions.

The primary goal lies in attaining precision alongside preventing tax avoidance to safeguard governmental budgeted funds.

Who Can Order a Special Audit?

A special audit is not a routine procedure. Only Deputy Commissioners (DC) along with Assistant Commissioners (AC) and officers ranking above them can launch this investigation upon obtaining permission from the Commissioner.

The audit begins when an officer chosen by approval undertakes the responsibility of nominating either a Chartered Accountant or Cost Accountant to perform audits and prepare reports within a scheduled deadline.
