Service Overview

About this Service

Overview of ADT-1 Filing (Auditor Appointment)

Form ADT-1 is filed with the MCA for appointing auditors under Section 139 of the Companies Act, 2013. Companies must appoint their first auditor within 30 days of incorporation (by board resolution) or within 90 days by shareholders if the board fails to appoint. Subsequent auditors are appointed for five-year terms at each AGM, with ratification at every AGM until the five-year term completes (though ratification requirement is optional under the Companies Amendment Act, 2017).

The filing must be done within 15 days of the appointment/reappointment at the AGM. Form ADT-1 requires details of the auditor (firm name, ICAI registration number, partner details), term of appointment, board resolution or AGM resolution details, and consent from the auditor. Individual auditors can serve two terms of five years each (total 10 years), while audit firms can serve two terms of five years each, followed by a cooling-off period of five years.

Casual vacancies due to resignation or removal require Form ADT-1 filing within 15 days of the board filling the vacancy. Non-filing attracts penalties and may render the appointment invalid, requiring reappointment. Auditor rotation is mandatory for listed and certain other classes of companies to ensure independence.

Who Should Opt for This Service?

Companies reappointing statutory auditors at AGMs
Entities filling casual vacancies due to auditor resignation

Note: ADT-1 must be filed within 15 days of auditor appointment; failure to file does not invalidate the appointment but attracts late fees and compliance defects.

Form ADT-1 is filed with the Registrar of Companies to intimate the appointment of statutory auditors after they are appointed in the Annual General Meeting (AGM). It is mandatory under Section 139 of the Companies Act, 2013.

ADT-1 must be filed within 15 days of the AGM in which auditors are appointed. For example, if the AGM is held on September 30, ADT-1 must be filed by October 15. Late filing attracts additional fees and penalties.

ADT-1 includes the company's CIN, details of the appointed auditor (name, firm registration number, address), the period of appointment, the resolution number and date of appointment, consent of the auditor, and details of the previous auditor if applicable.

First auditors appointed by the board within 30 days of incorporation (or by shareholders if board fails) do not require ADT-1 filing. ADT-1 is only required for auditors appointed in the first AGM and subsequent AGMs.

Late filing of ADT-1 attracts additional government fees based on the delay period. The company and officers in default may also face penalties under the Companies Act for non-compliance with statutory filing requirements.

If there are errors in the filed ADT-1, a revised form can be filed with corrected details. However, it is advisable to ensure accuracy in the first filing to avoid complications and multiple filings.

Documents include the consent letter from the auditor (Form ADT-1), copy of the board resolution or AGM resolution appointing the auditor, and the certificate of the auditor if applicable. These are uploaded as attachments to the e-form.

Non-filing results in the company being marked as non-compliant, penalties on the company and officers, inability to file certain other forms, and potential scrutiny by ROC. It also affects the company's compliance rating.

Yes, ADT-1 must be digitally signed by a director and certified by a practicing professional (Company Secretary, Chartered Accountant, or Cost Accountant). The auditor's consent must also be digitally signed where applicable.

Statutory auditors are typically appointed for 5 years subject to ratification at every AGM. However, individual auditors or audit firms have a maximum tenure of 5 years or 2 terms of 5 years each with a cooling-off period, as per rotation requirements for certain classes of companies.
