Form ADT-1 Appointment of Auditor
The appointment, resignation, or removal of an auditor is a highly regulated process, designed to ensure financial transparency, protect stakeholder interests, and maintain the independence of the auditing process.
Whether you operate a private limited company, a Limited Liability Partnership (LLP), or a sole proprietorship, the rules governing how you change auditor vary significantly. In this detailed guide, we will explore the statutory requirements, mandatory filings, fee structures, and the exact procedures you must follow to remain fully compliant with the law.
Understanding the Basics: What is Form ADT-1?
For companies registered under the Companies Act, 2013, notifying the Registrar of Companies (ROC) about your auditor is a strict statutory requirement. If you are wondering exactly what is form adt 1, it is the mandatory e-form used by a company to intimate the ROC about the appointment of an auditor.
To further clarify what is adt 1 form, you can think of it as the official auditor appointment form. It captures vital details such as the category of the auditor (whether an individual practitioner or a firm), the auditor’s Permanent Account Number (PAN), their Chartered Accountancy membership number, address, email ID, the period for which the appointment is made, and the date of the appointment. If the filing is due to a vacancy, the form also requires the membership number of the vacated auditor and the date and reason for the casual vacancy.
The First Auditor: Recent Legal Amendments
A very frequent question I receive from startup founders is: is adt 1 required for first auditor?
The answer is a resounding yes. Previously, companies enjoyed an exemption and were not required to file Form ADT-1 for the appointment of their very first auditor. However, a major MCA amendment that took effect on July 14, 2025, removed this exemption. Today, it is absolutely mandatory for all companies (both new and existing) to file Form ADT-1 within 15 days of appointing their first auditor.
For non-government companies, the Board of Directors is legally obligated to appoint the first auditor within 30 days of the company’s incorporation. If the Board fails to do so, the members (shareholders) must step in and appoint the auditor at an Extraordinary General Meeting (EGM) within 90 days. Regardless of whether the Board or the members make the appointment, the auditor appointment form (ADT-1) must be filed within 15 days of that appointment date.
The Process for Change of Auditor in Private Limited Company
When a business matures, a change of auditor in private limited company may occur due to mandatory rotation, voluntary resignation, or removal by the management. Here is how each scenario is governed:
- Mandatory Rotation of Auditors To preserve audit independence, the Companies Act mandates the rotation of auditors for prescribed classes of companies. An individual auditor cannot be appointed for more than one term of 5 consecutive years, while an audit firm cannot serve for more than two terms of 5 consecutive years. After this tenure, a 5-year cooling-off period applies before they can be reappointed. Notably, this strict rotation rule is not applicable to small companies and One Person Companies (OPCs).
- Resignation of an Auditor If an auditor decides to resign from your company, they are legally required to file Form ADT-3 with both the company and the ROC within 30 days from the date of their resignation. This creates a “casual vacancy.” The Board of Directors must fill this casual vacancy within 30 days. Furthermore, because the vacancy was caused by a resignation, the new appointment made by the Board must be formally approved by the shareholders at an EGM within 3 months. Following this appointment, the company must file Form ADT-1 within 15 days.
- Removal of an Auditor Before Expiry of Term Removing an auditor before their term expires is a stringent process to prevent management from dismissing auditors simply for raising financial red flags. To execute a change of auditor in private limited company via removal, the following steps must be strictly adhered to:
- A special notice must be received for the removal of the auditor.
- The Board of Directors must hold a meeting to discuss the removal and pass a board resolution.
- The company must file an application with the Central Government within 30 days of the board meeting.
- The concerned auditor must be given a reasonable opportunity to be heard before any final action is taken.
- Once the Central Government’s approval is received, the company must hold a general meeting within 60 days to pass a special resolution.
- Form ADT-2 must be filed to formalize the removal.
Auditor Changes in LLPs and Proprietorships
While the Companies Act strictly dictates the use of Form ADT-1, the rules differ significantly for other business structures. Clients often ask me, “What is the specific form for auditor appointment in llp?”
For Limited Liability Partnerships (LLPs): Unlike private limited companies, there is no specific MCA e-form like ADT-1 designated as the form for auditor appointment in llp. First, it is important to note that an audit of books is not automatically mandatory for all LLPs. An audit is only legally required for an LLP if, in any financial year, its turnover exceeds Rs. 40 Lakhs or its capital contribution exceeds Rs. 25 Lakhs.
If your LLP crosses these thresholds, you must appoint a qualified auditor. While you do not file an ADT-1 to announce this appointment, the auditor’s presence is validated during your annual compliance filings. Specifically, when filing Form 8 (Statement of Accounts and Solvency), if an audit is applicable to your LLP, the form must be digitally signed by your appointed auditor in addition to the designated partners. Therefore, a change in your LLP’s auditor is simply reflected internally via partner resolutions and externally when the new auditor digitally signs your annual Form 8.
For Sole Proprietorships: Sole proprietorships are not governed by the Ministry of Corporate Affairs, and therefore, no ROC forms (like ADT-1) apply to them. A proprietorship only requires an audit if it crosses the turnover thresholds prescribed under Section 44AB of the Income Tax Act (Tax Audit). To change auditor in a proprietorship, the proprietor simply issues a formal letter of appointment to the new Chartered Accountant and an NOC (No Objection Certificate) is communicated between the incoming and outgoing auditors as per the professional ethics guidelines of the ICAI.
Step-by-Step Procedure to File Form ADT-1
For companies, ensuring that the auditor appointment form is filed correctly is essential to avoid compliance flags. Here is the step-by-step process:
- Obtain Written Consent and Eligibility Certificate: Before filing, the company must obtain a formal written consent from the proposed auditor. The auditor must also provide a certificate confirming that they are eligible for appointment, that the appointment is within the limits laid down by the Act, and that they are not disqualified under the Companies Act or the Chartered Accountants Act.
- Hold a Board/General Meeting: Depending on whether it is a first auditor or a subsequent auditor, pass the necessary Board Resolution or Ordinary Shareholder Resolution.
- Access the MCA V3 Portal: Log in to the MCA portal and navigate to the e-forms section to download or fill Form ADT-1.
- Fill in the Details: Provide the company’s CIN, and the auditor’s details (PAN, firm registration number, address, email), and specify the period of appointment. Since the 2025 amendment, you must carefully select the nature of the appointment from the dropdown menu (e.g., First Auditor by Board of Directors, First Auditor by Members, etc.).
- Attach Documents: Upload scanned, certified PDF copies of the Board/Ordinary Resolution, the auditor’s written consent, and the eligibility certificate.
- Apply Digital Signatures (DSC): The form must be digitally signed by an authorized director of the company. It must also be certified by a practicing professional (a CA, CS, or CMA in whole-time practice) who will affix their own DSC.
- Submit and Pay Fees: Submit the form and pay the required ROC fees. Upon successful submission, an SRN (Service Request Number) will be generated for your records.
Government Fees and Penalties for Form ADT-1
The statutory fee for filing Form ADT-1 is calculated based on the authorized share capital of your company.
- Share Capital up to Rs. 1,00,000: Rs. 200.
- Rs. 1,00,001 to Rs. 4,99,999: Rs. 300.
- Rs. 5,00,000 to Rs. 24,99,999: Rs. 400.
- Rs. 25,00,000 to Rs. 99,99,999: Rs. 500.
- Rs. 1,00,00,000 or more: Rs. 600.
- Companies without share capital: Rs. 200.
Beware of Late Filing Penalties: Failing to file ADT-1 within the strict 15-day deadline results in escalating late fees based on the period of delay:
- Up to 30 days delay: 2 times the normal fees.
- 30 to 60 days delay: 4 times the normal fees.
- 60 to 90 days delay: 6 times the normal fees.
- 90 to 180 days delay: 10 times the normal fees.
- More than 180 days delay: 12 times the normal fees.
In addition to late fees, the company and every officer in default can face severe penalties under Section 147 of the Companies Act, with fines ranging from Rs. 25,000 to Rs. 5 Lakhs for the company, and Rs. 10,000 to Rs. 1 Lakh for the defaulting officers.
