Form ADT-1


Form ADT-1

Form ADT-1 is filed by every company to intimate the Registrar of Companies regarding the appointment of an auditor.

Filing of Form ADT-1

Before the establishment of the Companies Act 2013, a company auditor was required to file Form 23B, immediately after receiving the appointment letter from the concerned company. E-form 23B has to be filed within 30 days from the date of receiving the appointment letter. With the introduction of Companies Act 2013, the procedure and responsibility of filing auditor appointment with the registrar of companies are changed.

According to Section 139(1) of the new companies act 2013, a company informs the auditor of appointment and simultaneously a notice of such appointment has to be filed with the registrar of companies in 15 days of the meeting in which the auditor is appointed. As mentioned in the rules, such notice of the auditor appointment has to be filled in form ADT-1.

Under the companies act 1956, an auditor was required to file Form 23B with Rs. 300 as filing fee with ROC. Now the responsibility of filing new form ADT-1 has been shifted from the auditor to the company.

From the financial year 2014-15, a company has to file form ADT-1 after appointing the auditor in the meeting. The previous time limit allowed was 30 days for filing form 23B, has been changed in the new companies act 2013 to 15 days from the date of the meeting in which the auditor has been appointed.
