In every company, an auditor plays an important role in checking the accuracy of financial records and ensuring that all accounting statements are true and fair. Ideally, he/she is responsible for all the financial work in an organization.
The Companies Act, 2013 has clearly laid down the qualification, disqualification, and appointment procedure for company auditors in India.
Let’s understand these rules in simple terms.
An auditor is a qualified professional who checks and verifies the financial books, statements, and reports of a company. Their main duty is to ensure that all accounts show a true and fair view of the company’s financial position.
According to Section 141(1) of the Companies Act, 2013, only a Chartered Accountant (CA) holding a valid certificate of practice can be appointed as an auditor of a company.
|
Auditor Qualification under Companies Act, 2013 |
|
|
Eligibility Criteria |
Description |
|
Qualification |
Must be a Chartered Accountant (CA) in practice. |
|
Firm as Auditor |
A firm of chartered accountants can also be appointed, provided all partners practicing in India are qualified CAs. |
|
Only an Individual/Firm |
Only an individual or firm can act as auditor, not a company or any other body corporate. |
|
Joint Auditors |
Companies may appoint more than one auditor as joint auditors. |
This means only a professional with sound accounting knowledge and experience, recognized by the Institute of Chartered Accountants of India (ICAI), can perform an audit for companies registered under the Act.
When we say an auditor is “qualified,” it means:
The person must hold a CA degree and a Certificate of Practice (COP).
The auditor must have sufficient experience and knowledge in accounting and auditing. He/she should be very aware of what is happening in the marketplace.
The person or firm should be independent, meaning they are not influenced by the company’s management.
So, any person who meets the auditor qualification standards under the Companies Act is eligible to examine company accounts. And keep in mind, it is a huge responsibility for anyone, as the data is huge and needs to be managed properly.
Just like the law defines who can be an auditor, it also clearly defines who cannot be appointed as one.
Section 141(3) of the Companies Act, 2013 lists the disqualifications of an auditor.

If any of these conditions apply, the auditor cannot be appointed or must resign if already appointed.

If they fail, the members (shareholders) must appoint the auditor within the next 90 days at an Extraordinary General Meeting (EGM).

After the first auditor’s term ends, the company must appoint an auditor for the next term at the first Annual General Meeting (AGM).

Once appointed, the company must inform the Registrar of Companies (ROC) by filing Form ADT-1 within 15 days of the appointment.
To appoint an auditor officially, the company needs the following:
Board Resolution for appointment.
Consent letter from the auditor under Section 139(1).
Certificate from the auditor confirming eligibility under Section 141.
Form ADT-1 filed with the ROC.
Here’s a simple step-by-step view of how an auditor is appointed:

As per Section 140(1) of the Companies Act:
An auditor can be removed before the expiry of their term by passing a special resolution in the general meeting.
Before that, the company must take prior approval from the Central Government.
The auditor must be given a reasonable opportunity to explain their position.
Steps for removal:
Pass a board resolution proposing removal.
Apply to the Central Government (Form ADT-2).
After receiving approval, pass a special resolution in the general meeting.
File a copy of the resolution with the ROC.
If the auditor wants to resign, they must:
Submit a written notice to the company and the Registrar (Form ADT-3).
Mention the reason for resignation clearly.
This ensures transparency and accountability in the process.
To maintain independence, the law requires rotation of auditors after a specific period.

To access all books of accounts and documents.
