Online Form ADT-1 Filing
Updated on October 14, 2025 05:27:40 PM
In order to notify the Ministry of Corporate Affairs (MCA) that a company has appointed an auditor, Form ADT‑1 must be submitted. All companies, except One Person Companies (OPCs), must designate an auditor at their first Annual General Meeting (AGM) and submit the information to the Registrar of Companies (ROC) using Form ADT‑1, as per Section 139(1) of the Companies Act, 2013.
Because it provides the ROC with the auditor's name, firm registration number, tenure, and consent to serve as the company's statutory auditor, the ADT‑1 filing is essential. Within 15 days of the end of the AGM where the auditor was appointed or reappointed, the ADT‑1 filing is due. There are ADT‑1 late fees if the business doesn't file by the deadline. Timely filing is crucial because the penalty includes additional fees that are calculated for each day of delay.
Form ADT‑1 is a requisite form to be submitted with the Ministry of Corporate Affairs (MCA) for intimating the appointment of an auditor by a company. As per Section 139(1) of the Companies Act, 2013, all companies except One Person Company (OPC) are required to appoint an auditor during their first Annual General Meeting (AGM) and submit the details to the Registrar of Companies (ROC) in Form ADT‑1.
Form ADT-1 is an intimation filed by every company with the registrar of companies at the MCA portal about the appointment of the Auditor of the company. Under section 139 of the Companies Act, 2013, all companies must file this form within 15 days of the annual general meeting where the new Auditor is appointed. It is required to be filed every year with ROC as a notice of appointment of the Auditor after the annual general meeting.

They've been very helpful in our registration with ICEGATE. It was a small thing with a small amount paid which somehow escalated to a very painful procedure. Never did they say "You've only paid so much. It's too much effort for us.".
Very pleased with their service. Prompt, professional and great communication. Definitely recommend. Special mention for Ms. Razia - she handled our case.
Professional Utilities is fully professional in their work, Rates are too low and genuine. Services and satisfaction are high so I highly recommended Professional Utilities.
They are one of the most genuine and reasonable people. I applied for lmpc certificate through them and they charged me a very nominal amount as compared to what other firms asked .
