Form ADT-4: Reporting Fraud of ₹1 Crore or More by Auditors
ADT-4 is used by auditors to report suspected fraud of ₹1 crore or more to the Central Government, after seeking the board's reply within 45 days.
Short answer
Form ADT-4 is the report a statutory auditor sends to the Central Government when, during the audit, they have reason to believe an offence of fraud of ₹1 crore or more is being or has been committed against the company by its officers or employees. The auditor first reports to the board or audit committee within two days, seeks a reply within 45 days, then files ADT-4 within 15 days.

When ADT-4 applies
Section 143(12) requires an auditor who, in the course of performing duties, has reason to believe that an offence of fraud involving the company is being or has been committed by its officers or employees, to report it. The route depends on the amount. Rule 13 of the Companies (Audit and Auditors) Rules, 2014 sets the threshold at ₹1 crore.
The duty also applies to cost auditors and secretarial auditors performing their duties under the Act. It does not apply to fraud committed by outsiders against the company, which is outside Section 143(12).
| Amount of suspected fraud | Reporting route |
|---|---|
| ₹1 crore or more | Report to Central Government in ADT-4 after board process |
| Below ₹1 crore | Report to audit committee or board within 2 days; disclosed in board's report |
Timeline under Rule 13
For fraud of ₹1 crore or more, the auditor follows a fixed sequence set out in Rule 13. The time limits are short, so auditors usually keep a dated working-paper trail of each step, including how and when the board or audit committee received the report.
- Within 2 days of knowledge, report to the board or audit committee and seek their reply or observations within 45 days
- On receiving the reply, or if none arrives within 45 days, forward the report with the reply and the auditor's comments to the Central Government within 15 days
- Send the report in ADT-4 to the Secretary, Ministry of Corporate Affairs, and file the e-form as prescribed
What goes into the report
ADT-4 asks for the nature of the fraud with description, approximate amount involved, the parties involved, whether the board or audit committee replied and their response, and the auditor's observations on that reply. The auditor signs with their DSC and states their membership number.
The report should be factual and limited to what the auditor has found in the course of the audit. Auditors take care to rely on documents and evidence collected during their work rather than speculation, and to record the basis for their belief, since the report may be examined by investigating agencies.
Penalty for not reporting
Section 143(15) provides that an auditor, cost accountant or company secretary in practice who fails to comply with Section 143(12) is liable to a penalty of ₹5 lakh in the case of a listed company and ₹1 lakh in the case of any other company. This is a personal liability of the professional, not the company.
Professional bodies such as ICAI can also treat failure to report as a matter for disciplinary action, and the National Financial Reporting Authority oversees auditors of certain classes of companies, including listed companies and large unlisted companies. Auditors therefore treat ADT-4 as a serious professional obligation.
What the company should do
For companies, the practical point is to respond to the auditor's report within 45 days with a considered reply. The board's report must disclose details of frauds reported by auditors that are not reportable to the Central Government. Companies facing a fraud report usually need legal and forensic advice quickly, and Refogo's partner advocates can provide legal advice on the company's response.
