Common questions

FAQs.

What should an auditor resignation letter contain in 2026?
It should state the effective date of resignation, the reasons, and any other facts relevant to the resignation — those are the three things Section 140(2) of the Companies Act, 2013 requires the auditor to put in the statement filed in Form ADT-3, and the letter is the attachment to that form. A complete letter also records the last report issued, the status of work in progress, matters the incoming auditor should know, the fee position, and the auditor's undertaking to file ADT-3 within 30 days. For a listed entity, SEBI's circular on auditor resignations prescribes its own information format in addition.
Within how many days must ADT-3 be filed after an auditor resigns?
Within 30 days from the date of resignation. The statement is filed by the auditor — not the company — with the company and the Registrar of Companies, and also with the Comptroller and Auditor-General of India where the company is one whose auditor is appointed by the CAG under Section 139(5) or 139(7). The 30 days do not wait for the Board to accept the resignation.
What is the penalty for not filing ADT-3?
The auditor is liable to a penalty of ₹50,000 or an amount equal to the auditor's remuneration, whichever is less, plus ₹500 for each day of continuing failure, subject to a maximum of ₹2 lakh (Section 140(3)). The ₹2 lakh ceiling replaced the earlier ₹5 lakh ceiling through the Companies (Amendment) Act, 2020, effective 21 December 2020 — several online summaries still quote the old figure.
Can a statutory auditor resign before completing the five-year term?
Yes. The Act recognises the auditor's right to resign and does not require the company's acceptance or a notice period; the consequence is a casual vacancy that the Board must fill within 30 days under Section 139(8), with members' approval within three months of the Board's recommendation. What the Act does demand is transparency — the reasons and relevant facts on the public record through ADT-3. Auditors of listed entities and their material subsidiaries must also meet SEBI's conditions on completing the limited review or audit for the period before the resignation takes effect.
What reasons can be given for resignation of an auditor in ADT-3?
The actual ones, stated specifically. Section 140(2) asks for "the reasons and other facts as may be relevant with regard to his resignation", so a bare formula does not meet the second limb where there was, for example, a scope limitation, information withheld, a disagreement on accounting treatment, unpaid fees or an independence threat. The statement is available for public inspection on the MCA register and is read by the incoming auditor, lenders and regulators.
Does the company have to file anything when its auditor resigns?
ADT-3 is the auditor's filing, but the company has its own steps: the Board notes the resignation and fills the casual vacancy within 30 days, the members approve the appointment at a general meeting convened within three months of the Board's recommendation, and the company files Form ADT-1 for the incoming auditor. A listed entity additionally discloses the resignation and the auditor's detailed reasons to the stock exchanges.
