Statutory auditor is an independent professional — a chartered accountant or firm of chartered accountants — appointed by a company to examine its financial statements and express an opinion on whether they present a true and fair view of the company's financial position. Under Indian law, the appointment, qualifications, and duties of auditors are governed by Sections 139 to 147 of the Companies Act, 2013.
Legal definition
Section 139(1) of the Companies Act, 2013 provides:
Every company shall, at the first annual general meeting, appoint an individual or a firm as an auditor who shall hold office from the conclusion of that meeting till the conclusion of its sixth annual general meeting and thereafter till the conclusion of every sixth meeting.
Section 141(1) specifies the qualifications:
A person shall be eligible for appointment as an auditor of a company only if he is a chartered accountant:
Provided that a firm whereof majority of partners practising in India are qualified for appointment as aforesaid may be appointed by its firm name to be auditor of a company.
Section 141(3) enumerates disqualifications, including a person who is a body corporate, an officer or employee of the company, a person who is a partner or employee of an officer or employee of the company, a person whose relative is a director or in the employment of the company as a director or key managerial personnel, or a person who holds any security of or interest in the company exceeding the prescribed limits.
How courts have interpreted this term
Deloitte Haskins & Sells LLP — NFRA Order (2022)
The National Financial Reporting Authority (NFRA), in its first major enforcement action relating to the audit of IL&FS Financial Services Limited, held the engagement partner and the audit firm liable for professional misconduct and failure to comply with Standards on Auditing. NFRA imposed a five-year debarment on the engagement partner and a monetary penalty of Rs. 25 lakh on the firm, establishing the first precedent for disciplinary action by NFRA under Section 132 of the Companies Act, 2013.
P.K. Mukherjee v. Registrar of Companies (Calcutta High Court)
The High Court held that the statutory auditor occupies a position of trust and acts as a watchdog for the shareholders. The auditor owes a duty of care not only to the company but to the members and creditors who rely on the audited financial statements to make economic decisions. The Court clarified that the auditor must exercise reasonable professional skill and care in conducting the audit.
Why this matters
The statutory auditor serves as the primary external check on the accuracy and reliability of a company's financial statements. The audit function is essential for capital markets, banking, and corporate governance — investors, creditors, regulators, and the public rely on the auditor's report to assess the financial health of a company. The collapse of IL&FS in 2018 and the Satyam fraud in 2009 underscored the critical importance of auditor independence and competence.
For practitioners, the Companies Act, 2013 introduced mandatory auditor rotation for prescribed classes of companies under Section 139(2). An individual auditor cannot be appointed for more than one term of five consecutive years, and an audit firm cannot be appointed for more than two terms of five consecutive years. After completing the maximum tenure, a cooling-off period of five years applies before reappointment. This provision was designed to prevent the development of familiarity threats to auditor independence.
The establishment of the National Financial Reporting Authority (NFRA) under Section 132 represents a major governance advancement. NFRA has the power to investigate professional misconduct of auditors and impose sanctions including debarment and monetary penalties, providing an additional enforcement mechanism beyond the Institute of Chartered Accountants of India (ICAI).

Frequently asked questions
Who appoints the statutory auditor?
The statutory auditor is appointed by the shareholders at the annual general meeting on the recommendation of the board and the audit committee. The first auditor of a company is appointed by the board within 30 days of incorporation. For government companies, the auditor is appointed by the Comptroller and Auditor General of India under Section 139(5).
Can a company remove its statutory auditor before the term ends?
Yes, but the process is stringent. Under Section 140(1), the auditor may be removed before the expiry of the term only by a special resolution, after obtaining prior approval of the Central Government. This protection ensures that auditors cannot be removed merely for expressing unfavourable opinions.
What is the auditor's liability for professional misconduct?
Under Section 147, if an auditor contravenes any provision of the Act, they are punishable with a fine of Rs. 25,000 to Rs. 5 lakh. If the contravention is committed knowingly or with intent to deceive, the auditor faces imprisonment of up to one year and a fine of Rs. 1 lakh to Rs. 25 lakh. NFRA may additionally impose debarment for up to ten years.
Is auditor rotation mandatory for all companies?
No. Mandatory rotation under Section 139(2) applies only to listed companies and prescribed classes of companies (including all companies with paid-up share capital of Rs. 20 crore or more, all companies with public borrowings from financial institutions or banks of Rs. 50 crore or more, and other prescribed companies). Other companies may voluntarily adopt rotation.
