What is ADT-1?
Form ADT-1 is used by a company to inform the Registrar of Companies(RoC) about the appointment or reappointment of its auditor, which is mandatory according to Section 139(1) of the Companies Act,2013. This form must be filed within 15 days from the conclusion of Annual General meeting( AGM) in which the appointment or reappointment is made.
Differences In V2 Portal Vs. V3 Portal
1.From PDF to Web based
In V2 portal companies had to download a PDF version of Form ADT-1, fill it online, attach the Digital Signature Certificate (DSC) and then upload the signed file to the MCA portal which often involved multiple steps,software issues and formatting challenges.
In the V3 portal the process is much more simple. This is completely web based, where the details can be entered directly on the portal, if needed save the form midway and submit when it's complete. There is no need to download or upload any PDF or attach a DSC manually where the digital authentication will be handled through the OTP based verification linked to email.
2.More Disclosure of Details
In the V2 portal the companies had to provide only the basic information about the auditor such as name, PAN and address.
In the V3 portal along with the basic information the companies must provide information about the audit firm’s individual members,need to mention the SRN of Form INC-28, wherever applicable, especially in cases involving tribunal orders. If an audit committee has been constituted, any remarks or observation from the committee must be included. A new declaration by the company regarding the auditor’s appointment has been made mandatory, in line with a rule notified on May 30, 2025.
