Auditor Rotation Services — Managing Mandatory Auditor Rotation Under Section 139(2).

Section 139(2) of the Companies Act, 2013 introduced mandatory auditor rotation for listed companies and prescribed classes of companies (including certain unlisted public companies), imposing a maximum tenure for which the same individual or audit firm can serve as a company's statutory auditor. An individual auditor can serve for a maximum of one term of five consecutive years; an audit firm can serve for a maximum of two consecutive terms of five years each (ten years in total). Once the maximum tenure is completed, the auditor must be mandatorily replaced, and cannot be re-appointed until a cooling-off period has elapsed.

The cooling-off period after completion of the maximum tenure is five years — during which neither the outgoing individual auditor nor any partner who was a part of the audit engagement can be re-appointed as the company's auditor, and neither an outgoing audit firm nor any firm in which any of its partners are partners can be re-appointed. The rotation requirement means companies must plan their auditor transition well in advance — ideally at least one year before the mandatory rotation date — to allow time to evaluate, select, and onboard a successor auditor without disruption to the financial reporting cycle.

Managing auditor rotation involves first computing the outgoing auditor's tenure from their original appointment date, confirming whether the rotation deadline falls in the current year or upcoming year, identifying and evaluating a successor auditor who is eligible under Section 141, obtaining the successor's consent and eligibility certificate, filing ADT-1 within 15 days of the AGM at which the successor is appointed, and issuing the Section 139 intimation letter. We audit the tenure records, plan the rotation timeline, support the successor selection process, and manage all required filings.
