A statutory auditor is an independent chartered accountant (or a CA firm) appointed under Section 139 of the Companies Act, 2013, to examine a company's books and certify that its financial statements present a true and fair view. No company, regardless of size or turnover, can legally skip this.
Appointment of auditor refers to the formal process of engaging this CA or firm, whether that's the first auditor right after incorporation, a subsequent auditor at the annual general meeting, or someone filling a casual vacancy created by resignation or disqualification. Removal of auditor refers to ending an auditor's term before it naturally expires — because this touches on auditor independence, the law makes it deliberately harder than appointment, needing a special resolution and, in most cases, prior approval from the Central Government (delegated to the Regional Director).
Confusing removal with simple non-reappointment is one of the most common errors companies make, and it's covered separately below.
A key update businesses should know about: the Companies (Audit and Auditors) Amendment Rules, 2025 made e-Form ADT-1 mandatory for first auditor appointments too, with the revised web-based form effective from 14 June 2025. Before this, many companies treated first auditor appointment as an internal board matter with no separate ADT-1 filing requirement. That gap is now closed, and companies still relying on older guidance risk missing this filing entirely.
Under Section 141(1) and (2): the person must be a practising Chartered Accountant under the Chartered Accountants Act, 1949; a firm, including an LLP, can be appointed if the majority of its partners practising in India are qualified chartered accountants; and where a firm is appointed, only the partners who are CAs may act and sign audit reports on the firm's behalf — other partners cannot sign.
Section 141(3) rules out several categories of people and entities. A company that misses one of these during appointment risks the whole appointment being invalid.
If any of these disqualifications arises after appointment, Section 141(4) says the auditor must vacate office immediately, no notice required, and the vacancy is treated as a casual vacancy.
First Auditor — appointed by the Board of Directors within 30 days of incorporation. If the board fails to act, shareholders must appoint the first auditor at an extraordinary general meeting within 90 days. The first auditor holds office until the conclusion of the first AGM.
Subsequent Auditor — appointed at the first AGM (or any AGM thereafter) for a term running until the conclusion of the sixth AGM, roughly five years, subject to ratification and rotation rules.
Casual Vacancy — when an auditor resigns, dies, or becomes disqualified mid-term, the board fills the vacancy within 30 days. If the vacancy was caused by resignation, shareholder approval at a general meeting is also needed within three months of the board's recommendation.
Government Company Auditor — for government companies, the Comptroller and Auditor General of India (C&AG) appoints the auditor within 180 days from the start of the financial year, not the shareholders.
Reappointment — a retiring auditor can be reappointed at an AGM unless they're disqualified, have given written notice of unwillingness, or a resolution has been passed appointing someone else or expressly not reappointing them.
A private limited company follows the same Section 139 framework as any other company, with two practical differences worth knowing: auditor rotation isn't mandatory unless the company's paid-up share capital reaches the prescribed threshold, or its public borrowings cross ₹50 crore; and the 20-company audit cap under Section 141(3)(g) doesn't apply to private companies with paid-up capital below ₹100 crore, provided the company hasn't defaulted on filing financial statements under Section 137. For a brand-new private limited company, the sequence is: incorporate, hold the first board meeting within 30 days, appoint the first auditor by board resolution, and file ADT-1. That auditor then continues, subject to shareholder ratification at each AGM, until the sixth AGM, unless rotation rules apply.
Public companies carry a few additional obligations: companies crossing the paid-up capital or turnover thresholds under Rule 6 of the Companies (Meetings of Board and its Powers) Rules must constitute an Audit Committee, and auditor appointments (including filling casual vacancies) must factor in that committee's recommendation; mandatory rotation applies more broadly to public companies; and listed companies and specified classes must also follow SEBI's disclosure requirements around auditor changes, in addition to Companies Act filings.
This is the process that trips up most companies, largely because it's stricter than people expect.
Grounds companies typically cite include persistent delays in submitting the audit report, unresolved conflicts with management over accounting treatment, discovery of fraud or serious professional misconduct, or a fundamental breakdown in the working relationship. Note that dissatisfaction with fees alone is a weak ground, and Regional Directors have refused applications built solely on cost.
These two get confused constantly, and the compliance steps are completely different.
If an auditor resigns, the board fills the resulting casual vacancy within 30 days, subject to shareholder ratification within three months where the vacancy arose from resignation.
Rotation applies to listed companies and to the classes of companies prescribed under Rule 5 of the Companies (Audit and Auditors) Rules, 2014.
Tenure limits: an individual auditor can serve one term of five consecutive years; an audit firm can serve two terms of five consecutive years each (ten years total). After that, a five-year cooling-off period applies before the same auditor or firm can be reappointed in the same company.
Both ADT-1 and ADT-3 now run on the MCA V3 web-based filing system, and ADT-3 filings must reference the SRN of the original ADT-1.
Government fees for these filings are modest and depend on the company's authorised capital slab (typical range: ₹200 to ₹600 per form, plus additional fee for delayed filing). Professional service fees vary by firm and complexity of the case.
These figures are indicative only. Actual charges depend on company size, urgency, and whether the Regional Director requires an in-person or virtual hearing. Get in touch for an exact quote based on your company's situation.
Total time for a contested removal, from the first board resolution to the special resolution being passed, commonly runs three to five months once hearing delays are factored in.
Section 147 sets out separate penalty tiers for the company, its officers, and the auditor.
A convicted auditor also has to refund fees received for that engagement and compensate the company, its members, creditors, or regulators for losses caused by a misleading audit report. Beyond the direct fine, operating without a validly appointed auditor means the company cannot get its financial statements audited, cannot file Form AOC-4, and sits in default on its annual compliance from that point forward. Directors of companies in persistent default also risk disqualification.
Yes, but only by special resolution after obtaining prior approval from the Central Government (via the Regional Director), and only after giving the auditor a reasonable opportunity to be heard.
Removal is company-initiated and needs Central Government approval plus a special resolution. Resignation is auditor-initiated and only needs the auditor to file Form ADT-3 within 30 days.
Yes. Since the Companies (Audit and Auditors) Amendment Rules, 2025, ADT-1 is mandatory for first auditor appointments as well, not just subsequent ones.
Within 15 days from the date of the meeting at which the auditor was appointed.
Only if paid-up share capital reaches ₹50 crore or more, or public borrowings/deposits reach ₹50 crore or more. Smaller private companies are exempt.
Yes, this is mandatory under Section 140(1) and skipping it can invalidate the removal process.
It's a weak ground on its own. Regional Directors have declined applications where fee disagreement was the sole stated reason.
At least 75% of the votes cast by members present and voting, in addition to the notice requirements for special resolutions.
They face imprisonment up to one year and a fine between ₹50,000 and ₹25,00,000, or eight times their remuneration, whichever is lower, along with an obligation to refund fees and compensate affected parties.
It varies, commonly four to twelve weeks depending on the Regional Director's workload and whether a hearing is required.
Appointing or removing a company auditor isn't paperwork you want to improvise. Appointment is fairly routine once you know the 15-day ADT-1 clock and the Section 141 eligibility checks. Removal is genuinely stricter: a hearing for the auditor, Regional Director approval, and a special resolution, in that order, not skipped or reordered.
