Form ADT-1 is the statutory MCA form through which every Indian company intimates the Registrar of Companies (RoC) of the appointment of its statutory auditor under Section 139 of the Companies Act 2013 read with Rule 4 of the Companies (Audit and Auditors) Rules 2014. Once shareholders appoint or re-appoint the statutory auditor at the AGM, the company must file Form ADT-1 with the RoC within 15 days of the AGM — capturing details of the auditor (firm name, FRN, partner-in-charge, ICAI membership, address), tenure of appointment, written consent under Sec 139, and certificate of eligibility under Sec 141. Non-filing or late filing of ADT-1 attracts additional fees per day and exposes the company and officers to penalties under Section 450 — and in serious cases, to scrutiny over the validity of the audit itself, with implications for the financial statements, AOC-4, MGT-7, and tax-audit framework.
