Under the Companies Act, 2013, every company must appoint a qualified auditor to review its financial statements and ensure compliance with applicable accounting and legal standards. The appointment process involves verifying eligibility, obtaining written consent, passing the necessary resolution and filing Form ADT-1 with the Registrar of Companies (ROC). Timelines and procedures vary depending on whether the company is a non-government company, a listed or specified company, or a government company.
Who Can Be Appointed as an Auditor
Only a practising Chartered Accountant (CA) or a firm of CAs registered under the Chartered Accountants Act, 1949 can be appointed as a statutory auditor in India. A CA firm or LLP is eligible where the majority of partners are practising CAs. The proposed auditor must also meet the eligibility requirements under Section 141 of the Companies Act, 2013 and must not be disqualified under any of the conditions specified therein.
Auditor appointment by company type
The timelines and procedures for auditor appointment differ based on the type of company.
Non-government companies
First auditor after incorporation
The Board of Directors must appoint the first auditor within 30 days of incorporation by passing a board resolution. If the Board fails to do so, the members must appoint the auditor within 90 days at an Extraordinary General Meeting (EGM).
Auditor appointment at the Annual General Meeting
Members appoint auditors at the Annual General Meeting (AGM) after receiving the auditor’s written consent and eligibility confirmation. For listed and certain specified companies, auditor rotation rules apply:
- Individual auditor: Maximum one term of 5 consecutive years
- Audit firm: Maximum two consecutive terms of 5 years each (10 years in total)
After completing the maximum term, a mandatory cooling-off period of 5 years is required before reappointment.
Casual vacancy
Resignation: The Board fills the vacancy within 30 days, and members must approve the appointment within three months at a general meeting.
Other reasons (death or disqualification): The Board may fill the vacancy within 30 days, and the appointed auditor holds office until the next AGM.
Listed or specified companies
First auditor after incorporation

Government companies
First auditor appointment
The first auditor of a government company is appointed by the Comptroller and Auditor General of India (CAG) within 60 days of incorporation.
If the CAG fails to appoint within this period:
- The Board of Directors must appoint the auditor within the next 30 days
- If the Board also fails, the members must appoint the auditor within 60 days at an EGM
Subsequent auditor appointment
For subsequent financial years, the CAG appoints the auditor within 180 days from the beginning of the financial year.

Board appointment: If the CAG is unable to do so, the Board of Directors must appoint the auditor within the next 30 days.
Steps to appoint an auditor
The general process for auditor appointment involves the following steps.
- Check eligibility: Confirm the proposed auditor is a practising CA, or CA firm or LLP where the majority of partners are practising CAs, and that the auditor meets the requirements under Section 141 of the Companies Act, 2013.
- Obtain consent and eligibility certificate: Get the auditor’s written consent and a certificate confirming the auditor is not disqualified and is eligible for appointment under Section 139 and Section 141 of the Companies Act, 2013.
- Pass the Board or member resolution: For a newly incorporated company, the Board passes a resolution within 30 days of incorporation. For subsequent appointments, members pass a resolution at the AGM.
- File Form ADT-1 with the ROC: File Form ADT-1 with the ROC within 15 days of the auditor’s appointment, including the appointment of the first auditor, as required under the current MCA filing framework.
- Confirm tenure: The auditor holds office from the conclusion of the AGM at which the appointment is made until the conclusion of the sixth AGM thereafter, unless removed earlier.
Auditor appointment by special notice

If a company proposes to replace the retiring auditor or not reappoint them, a special notice must be given under Section 115 of the Companies Act, 2013, before moving the resolution at the AGM.
A special notice is not required if the retiring auditor cannot be reappointed due to the completion of the maximum tenure under the auditor rotation provisions.
If the retiring auditor submits a written representation, the company must inform members in the meeting notice and circulate the representation. If circulation is not possible in time, the representation must be sent to the ROC and read out at the meeting.
