Auditor Appointment Under Section 139 — Complete Guide 2026

VS Vikas Sharma 📅 March 25, 2026 ⏱️ 5 min read 👁️ 3 views Updated: Mar 27, 2026

Why Auditor Appointment Is Strictly Regulated

The statutory auditor is the shareholders' watchdog — they independently examine the company's financial statements and report whether they present a true and fair view. The Companies Act, 2013 significantly strengthened auditor appointment provisions compared to the 1956 Act: mandatory rotation (to prevent over-familiarity between auditor and management), stricter independence criteria (Section 141), and criminal liability for fraud (Section 143(12)). Getting the appointment process wrong can attract penalties on the company, invalidate the audit, and create complications in annual filing.

First Auditor — Section 139(6)

The first auditor must be appointed by the Board of Directors within 30 days of incorporation. The first auditor holds office from the date of appointment until the conclusion of the first Annual General Meeting. At the first AGM: the shareholders appoint the auditor for the regular term (5 years).

If the Board fails to appoint within 30 days: the members (shareholders) must appoint the first auditor within 90 days at an EGM. The default of 30 days attracts a penalty of Rs. 300 per day.

For Government companies: the first auditor is appointed by CAG (Comptroller and Auditor General) within 60 days of incorporation. If CAG does not appoint within 60 days: the Board appoints within the next 30 days.

Subsequent Auditor — Section 139(1)

At every AGM, the company appoints (or re-appoints) the statutory auditor. The appointment is for a term of 5 consecutive years — subject to ratification at every AGM (ratification requirement removed for companies other than those requiring auditor rotation, by Companies Amendment Act, 2017 — but many companies still ratify as best practice).

Appointment Process

Step 1: Board meeting before AGM — Board recommends the auditor for appointment/re-appointment. Consider: qualifications, independence, fees, capacity to handle the audit.

Step 2: Obtain written consent from the proposed auditor (consent letter) and certificate of eligibility under Section 141 (confirming: not disqualified, within the ceiling of audits, no conflict of interest).

Step 3: Place the appointment as item of ordinary business at AGM. Members approve by ordinary resolution.

Step 4: File ADT-1 with ROC within 15 days of AGM — intimating the appointment details.

Mandatory Rotation — Section 139(2)

Applicable to specified companies: listed companies, unlisted public companies with paid-up capital ≥ Rs. 10 crore, private companies with paid-up capital ≥ Rs. 50 crore, all companies with public borrowings from banks/FIs ≥ Rs. 50 crore.

Auditor TypeMaximum Consecutive TermCooling-Off Period
Individual auditor1 term of 5 consecutive years5 years before re-appointment
Audit firm2 terms of 5 consecutive years (10 years total)5 years before re-appointment

Private companies exempt from rotation: Unless the private company meets the Rs. 50 crore paid-up capital threshold, rotation does NOT apply. Most private companies can retain the same auditor indefinitely. However, as a governance best practice, rotation every 5-10 years is recommended.

Removal of Auditor Before Expiry of Term — Section 140(1)

Removing an auditor before completing their 5-year term is a complex process requiring:

(a) Special resolution at a general meeting (75% majority)

(b) Prior approval of the Central Government (application to Regional Director within 30 days of passing the Board resolution proposing removal — RD decides within 30 days)

(c) The auditor must be given a reasonable opportunity to be heard at the general meeting

(d) The auditor can make representations in writing to the company — which must be sent to all members

This high bar for removal protects auditor independence — management cannot easily fire an auditor who gives uncomfortable audit opinions.

Resignation of Auditor — Section 140(2)-(3)

An auditor who resigns must:

(a) File ADT-3 (notice of resignation) with the company AND with the ROC within 30 days of resignation

(b) State the reasons for resignation — this is filed with ROC and becomes a public document

(c) For companies specified under Section 139(2): the resigning auditor must also file a statement of concerns (if any) with the company and ROC

The resignation becomes effective from the date the company receives it — the company must appoint a replacement within 30 days.

Casual Vacancy — Section 139(8)

If a casual vacancy arises in the office of auditor (due to death, disqualification, or resignation):

(a) Vacancy NOT caused by resignation: the Board fills the vacancy within 30 days. The appointee holds office until the conclusion of the next AGM.

(b) Vacancy caused by resignation: the Board fills the vacancy within 30 days — BUT the appointee must be approved by the members at an EGM to be called within 3 months.

Eligibility and Disqualification — Section 141

Who CAN be appointed:

(a) Chartered Accountant holding certificate of practice (for individual appointment)

(b) Firm of Chartered Accountants (where majority of partners are CAs holding COP)

(c) LLP of Chartered Accountants

Who CANNOT be appointed (disqualified):

(a) Body corporate (company/LLP — only CA firm/LLP of CAs allowed)

(b) Officer or employee of the company

(c) Person who is a partner of, or in employment of, an officer/employee of the company

(d) Person who, or their relative, holds any security or interest in the company (de minimis: can hold up to Rs. 1 lakh face value)

(e) Person indebted to the company for more than Rs. 5 lakh

(f) Person who has given guarantee for indebtedness of third party to the company for more than Rs. 1 lakh

(g) Person holding appointment as auditor in more than 20 companies (for individual) or 20 companies per partner (for firm)

(h) Person convicted of fraud and 10 years have not elapsed from conviction

(i) Person who has directly or indirectly rendered any non-audit service (management consultancy, actuarial, investment advisory, etc.) prohibited under Section 144

Ceiling on Number of Audits
An individual CA cannot be auditor of more than 20 companies (excluding OPC, dormant, small companies, and private companies with paid-up capital < Rs. 100 crore). For a CA firm: 20 companies per partner. Example: firm with 4 partners can audit up to 80 companies (20 × 4). Before accepting appointment: the CA must issue an eligibility certificate (Section 139(1) proviso) confirming they are within the ceiling.

Penalty for Non-Appointment

If the company does not appoint an auditor within 30 days of incorporation (first auditor) or at the AGM (subsequent auditor):

(a) Company: penalty of Rs. 25,000, and Rs. 5,000 per day of continuing default

(b) Every director in default: penalty of Rs. 10,000 to Rs. 1 lakh

Additionally, the company cannot file AOC-4 (financial statements) without an audited report — creating a cascading compliance failure. The ROC can also direct the company to appoint an auditor through intervention.

❓ Frequently Asked Questions
When must the first auditor be appointed after incorporation?
Within 30 days of incorporation — by the Board of Directors. The first auditor holds office until the conclusion of the first AGM. If the Board fails to appoint within 30 days: the members must appoint at an EGM within 90 days. Penalty for default: Rs. 300 per day. The first auditor is typically a CA firm recommended by the promoters. File ADT-1 with ROC: NOT required for first auditor appointment (ADT-1 is required only for appointments made at AGMs).
What is the maximum term for a statutory auditor?
5 consecutive years per term. For companies subject to mandatory rotation: individual auditor = maximum 1 term (5 years), audit firm = maximum 2 terms (10 years). After completing maximum term: cooling-off period of 5 years before re-appointment. For private companies NOT subject to rotation (paid-up capital below Rs. 50 crore): the same auditor can be appointed indefinitely — there is no maximum term limit. However, governance best practice recommends rotation every 5-10 years.
Can the company remove its auditor before the term expires?
Yes — but it requires a very high threshold: (1) special resolution at general meeting (75% majority), (2) prior approval of Central Government (application to Regional Director), (3) the auditor must be given opportunity to be heard at the general meeting, (4) the auditor can make written representations which must be circulated to all members. This deliberately high bar protects auditor independence — preventing management from removing auditors who give adverse opinions or report fraud.
Is auditor rotation mandatory for private companies?
Not for most private companies. Mandatory rotation under Section 139(2) applies only to: listed companies, unlisted public companies with paid-up capital ≥ Rs. 10 crore, ALL companies with public borrowings ≥ Rs. 50 crore, and private companies with paid-up capital ≥ Rs. 50 crore. Most private companies have paid-up capital well below Rs. 50 crore — they are exempt from rotation and can retain the same auditor for any number of terms.
What services can the statutory auditor NOT provide to the company?
Section 144 prohibits the statutory auditor from providing these services (directly or indirectly) to the company or its holding/subsidiary: (1) accounting and bookkeeping, (2) internal audit, (3) design and implementation of financial information system, (4) actuarial services, (5) investment advisory, (6) investment banking, (7) management services, (8) any other service as prescribed. The auditor's network (associated firms/entities) is also covered by this prohibition. Violation: penalty on auditor (Rs. 25,000 to Rs. 5 lakh) and potential disqualification.
