Step-Wise Process for Auditor Resignation

The resignation process involves mandatory actions by both the resigning auditor and the company, with strict timelines under Sections 140(2) and 139(8) to avoid penalties.

1

Step 1: Submission of Formal Resignation Letter

The Statutory Auditor submits a detailed resignation letter to the Board of Directors, clearly stating specific reasons (health issues, fee disputes, independence concerns) and the effective resignation date. This triggers all statutory deadlines under Section 140(2). The letter becomes a mandatory attachment for Form ADT-3.

2

Step 2: Convening Board Meeting (Company Action)

The Company must convene a Board Meeting within 7-10 days of receiving the resignation letter. The Board passes a resolution accepting the resignation, noting the effective date, and initiating the search for a replacement auditor. Minutes must be documented appropriately as they are required for subsequent filings.

3

Step 3: Filing Form ADT-3 (Auditor's Critical Compliance)

The resigning auditor must file Form ADT-3 electronically with the ROC within 30 days from the resignation date stated in the letter. This is a personal obligation of the auditor under Section 140(2). Attachments Required: Resignation letter (mandatory). Penalty for Delay: ₹50,000 or remuneration amount (whichever is less) plus ₹500 per day up to ₹ two lakhs

4

Step 4: Filling the Casual Vacancy (Board Appointment)

Under Section 139(8)(i), the Board must appoint a new auditor within 30 days of the resignation to fill the casual vacancy. This appointment requires shareholders’ ratification at a General Meeting within three months. The company then files Form ADT-1 within 15 days of the appointment.

What is the ADT-3 Form, and who has to file it?

When an auditor resigns from their position, they must file a Form ADT-3 with the Registrar of Companies (RoC) within 30 days of the resignation. This statement must be digitally signed by the auditor using his DSC and, along with his resignation letter, submitted online at the MCA portal with the prescribed application fee. The table below details the contents of the ADT-3 Form and the government filing fee.

Auditor Resignation vs. Auditor Removal

While resignation is a voluntary act by the auditor, removal is the company’s action to dismiss the auditor before their term ends. The legal procedures differ significantly.

NoFeatureAuditor ResignationAuditor Removal
1InitiatorThe Auditor (Voluntary).The Company (Involuntary).
2Primary SectionSection 140(2).Section 140(1).
3Govt ApprovalNot Required.Required (Regional Director approval).
4Forms InvolvedADT-3 (Filed by Auditor).ADT-2 (Application to RD) & MGT-14.
5TimelineImmediate effect (subject to ADT-3 filing).Takes months (requires Board, RD, and Shareholder approval).
6Key RequirementFiling ADT-3 within 30 days.A reasonable opportunity to be heard is given to the auditor.

Quick Takeaway: Resignation is simpler and faster, but requires the auditor to be diligent with Form ADT-3. Removal is a complex, quasi-judicial process used only when there is a serious breach or dispute. If you are an auditor, ensure you file ADT-3; if you are a company, ensure you fill the vacancy immediately. ✅

Contravention and Penalty – Resignation of Auditor

Section 140 of the Companies Act, 2013, governs auditor resignation and requires a written notice at least 30 days before the resignation date. Violations such as failing to provide timely notice, neglecting to submit Form ADT-3, or failing to comply with the Act’s provisions can result in penalties, including fines or imprisonment. Auditors and the Board of Directors of the companies are therefore urged to abide by these regulations to avoid potential sanctions.

Suppose any of the provisions relating to an auditor resigns without giving the required notice. In that case, he or she will be liable to a penalty of ₹50,000 or an amount equal to the remuneration of the auditor, whichever is less. In case of continuing failure, a further penalty of ₹500 for each day after the first during which such failure continues, subject to a maximum of ₹2,00,000, may be imposed.

Amendment The Companies (Amendment) Act, 2020, increased the maximum penalties for auditor resignation and for non-filing of Form ADT-3 to ₹ 2 lakh from ₹ 50,000. The amendment came into force on 29 September 2020.

Frequently Asked Questions

What is the exact penalty if the auditor fails to file Form ADT-3 within 30 days?

As per Section 140(3) as amended by the Companies (Amendment) Act, 2020, the penalty is ₹50,000 or the auditor’s remuneration, whichever is less. For continuing default, an additional ₹500 per day applies, subject to a maximum of ₹2 lakhs for the auditor.

Is an auditor's resignation governed by any section other than Section 140?

While Section 140(2) primarily governs resignation procedures, Section 139(8) governs the filling of casual vacancies, and Rule 8 of the Companies (Audit and Auditors) Rules, 2014, prescribes the requirements for Form ADT-3.

Can an auditor withdraw their resignation after submitting it?

Legally, once the resignation letter is submitted and the Board accepts it, withdrawal requires Board consent through a fresh resolution. However, if Form ADT-3 has already been filed with the ROC, withdrawal becomes procedurally complex.

What happens if the company doesn't accept the auditor's resignation?

Resignation is a unilateral right under Section 140(2). It becomes effective from the date mentioned in the letter or receipt date, whichever is later. Company acceptance is procedural; they cannot force continuation.

Are there different rules for a Government Company auditor's resignation?

Yes, under Section 140(2), Government Company auditors must also file the resignation statement with the Comptroller and Auditor-General of India (CAG) within the same 30-day timeline.

What constitutes "continuing failure" for penalty purposes?

Continuing failure begins from day 31 after resignation if Form ADT-3 isn’t filed. Each day attracts a penalty of ₹500 until filing or reaching the ₹2 lakh cap, as per Section 140(3).

Who is responsible for filing Form ADT-3 - the auditor or the company?

The resigning auditor is solely responsible for filing Form ADT-3. The company cannot file on the auditor’s behalf. This is a personal statutory obligation under Section 140(2).

What documents must be attached to Form ADT-3?

The resignation letter is a mandatory attachment. Additional optional attachments may include correspondence explaining the reasons for resignation, though this is not statutorily required.

Can Form ADT-3 be filed in paper format, or is e-filing mandatory?

Form ADT-3 is an e-form that requires a digital signature and online filing through the MCA portal. Physical filing has not been permitted since September 2014.

What is the fee structure for filing Form ADT-3?

Fees vary by share capital: companies with share capital pay based on authorised capital slabs (₹200-₹600), companies without share capital pay ₹200, and foreign companies pay ₹6,000.

Is Form ADT-3 required if the auditor completes their full term?

No, Form ADT-3 is only for mid-term resignations creating casual vacancies. Natural completion of 5-year tenure or retirement at AGM doesn’t require ADT-3.

Can multiple auditors file a single Form ADT-3 for joint resignation?

Each resigning auditor must file a separate Form ADT-3 even in joint audit scenarios. Individual responsibility cannot be consolidated into a single filing.

How is a casual vacancy different from a regular vacancy?

A casual vacancy arises unexpectedly during tenure (death, resignation, disqualification), while a regular vacancy occurs at the natural term’s completion. Different appointment procedures apply under Section 139(8).

Can the Board permanently appoint a new auditor after resignation?

No, Board appointment under Section 139(8) is temporary. Shareholders must ratify within three months, and the appointee holds office only till the next AGM.

What if the Board doesn't appoint within 30 days?

Failure to fill a casual vacancy within 30 days may constitute non-compliance under Section 139(8), potentially attracting penalties under Section 450 for officers in default.

Does a casual vacancy appointment count towards the 5-year tenure limit?

This is debated, but the predominant view is that casual vacancy appointments till AGM don’t constitute a “term” under Section 139(2) rotation requirements.

Can the resigning auditor be reappointed to fill their own vacancy?

Technically possible if the auditor withdraws resignation with Board consent before filing ADT-3, but once filed, reappointment would be a fresh appointment.

Is shareholder approval always required for casual vacancy appointments?

Yes, for resignations. A board appointment requires shareholders’ ratification within 3 months. However, for other casual vacancies (e.g., death, disqualification), Board appointment suffices until the AGM.

What if an audit firm dissolves - is it treated as a resignation?

Dissolution creates an automatic casual vacancy without requiring Form ADT-3, as it’s not a voluntary resignation. The Board directly appoints under Section 139(8).

Can an auditor resign during an ongoing statutory audit?

While legally permissible, professional ethics under ICAI guidelines discourage mid-audit resignations unless exceptional circumstances exist and require detailed documentation of the reasons for the resignation.

Does a branch auditor's resignation require Form ADT-3?

No, Form ADT-3 applies only to statutory auditors appointed under Section 139. Branch auditors appointed under Section 143(8) follow different procedures.

What if the auditor resigns after discovering company fraud?

The auditor must still follow Section 140(2) procedures, but also has an obligation under Section 143(12) to report fraud to the Central Government.

Is resignation valid if given verbally in a Board meeting?

No, Section 140(2) requires a written resignation. Verbal intimation doesn’t trigger statutory timelines or filing obligations until a formal written submission is made.

Can a removed auditor claim compensation?

If removed without a valid cause before term completion, the auditor may have contractual claims for compensation, though the Companies Act doesn’t specifically provide for this.

Should the reasons in Form ADT-3 match the resignation letter exactly?

Yes, consistency is crucial. Any discrepancy between the reasons for resignation stated in the resignation letter and those disclosed in the Form ADT-3 may raise regulatory questions and professional conduct issues.

What constitutes "professional preoccupation" as a resignation reason?

ICAI recognises health issues, excessive workload preventing quality audit, relocation, or other professional commitments as valid professional preoccupation grounds.

Can fee disputes alone justify an auditor's resignation?

Yes, persistent non-payment despite reminders is a valid ground. However, resignation shouldn’t be threatened as a fee-recovery pressure tactic, per professional ethics.

How should companies handle auditor resignations during AGM season?

If a resignation occurs close to the AGM, the Board may immediately appoint, with ratification at the upcoming AGM, rather than calling a separate EGM.

What if ROC rejects Form ADT-3?

Common rejection reasons include incorrect attachments, fee issues, or data mismatches. Resubmission must occur immediately as the 30-day deadline doesn’t extend.

Should the resignation letter specify the Section 140(2) reference?

While not mandatory, referencing Section 140(2) and stating the intention to file Form ADT-3 demonstrates professional awareness and a commitment to statutory compliance.
