Changing your company’s auditor is one of the most procedurally complex compliance tasks under the Companies Act, 2013. Unlike other compliance filings, it involves multiple parties (company, outgoing auditor, incoming auditor, Central Government), multiple forms (ADT-1, ADT-2, ADT-3, MGT-14), and strict timelines that cascade into each other.
The complexity is compounded by the fact that there are five completely different procedures depending on why the auditor is changing: resignation, removal, rotation, non-reappointment, or death/disqualification. Most businesses (and even some professionals) conflate these scenarios, leading to incorrect filings and penalties.
This blog maps all five scenarios with step-by-step processes, forms, timelines, documents, and penalties - providing the complete reference for any Indian business facing an auditor change.
What Does ‘Change of Auditor’ Mean Under the Companies Act?
Under the Companies Act, 2013, change of auditor means any event that results in a different person or firm serving as the statutory auditor of the company. This includes voluntary changes (company decides to change) and involuntary changes (auditor resigns, dies, or becomes disqualified).
The governing sections are: Section 139 (appointment, reappointment, rotation), Section 140 (removal, resignation), and Section 141 (eligibility, disqualification). The corresponding rules are in the Companies (Audit and Auditors) Rules, 2014 (as amended in 2025). Businesses using statutory audit services (know more) get auditor change management as part of the compliance lifecycle.
Key Terms You Should Know
ADT-1: Form filed by the company with ROC to notify the appointment of a new auditor. Due within 15 days of appointment.
ADT-2: Application filed by the company with the Central Government (Regional Director) seeking approval to remove the auditor before term expiry. Filed within 30 days of Board resolution.
ADT-3: Statement filed by the resigning auditor with the company and ROC within 30 days of resignation, stating reasons and relevant facts.
MGT-14: Form filed with ROC for any special resolution passed. Required when: auditor is removed (special resolution), or when a retiring auditor is not reappointed (special notice + resolution).
Casual Vacancy: Vacancy in the office of auditor before the expiry of their term. Arises from: resignation, death, or disqualification.
Section 140(1) - Removal: Company removes auditor before term end. Requires: Board resolution + ADT-2 to Central Government + approval + special resolution at general meeting within 60 days.
Section 140(2) - Resignation: Auditor voluntarily resigns. Files ADT-3. Company fills casual vacancy.
NOC - No Objection Certificate: Not legally mandatory, but recommended professional practice: outgoing auditor provides NOC to incoming auditor. Signals clean handover.
The Five Scenarios for Change of Auditor
| # | Scenario | Legal Basis | Who Acts First | Forms Required | Timeline | Central Govt? |
|---|---|---|---|---|---|---|
| 1 | Auditor resigns | Section 140(2) | Auditor (submits resignation) | ADT-3 (auditor) + ADT-1 (company, new auditor) | ADT-3: 30 days. Board fills vacancy: 30 days. EGM: 3 months. ADT-1: 15 days. | No |
| 2 | Company removes auditor (before term) | Section 140(1) | Company (Board resolution) | ADT-2 (Central Govt) + MGT-14 (special resolution) + ADT-1 (new auditor) | ADT-2: 30 days of Board res. General meeting: 60 days of approval. ADT-1: 15 days. | Yes - ADT-2 approval required |
| 3 | Mandatory rotation (term expires) | Section 139(2) | Company (Audit Committee recommends) | ADT-1 (new auditor) | At AGM where term expires. ADT-1: 15 days after AGM. | No |
| 4 | Non-reappointment at AGM (retiring auditor not reappointed) | Section 140(4) | Company (special notice by member) | ADT-1 (new auditor) + MGT-14 (if special resolution) | Special notice: 14 days before AGM. Resolution at AGM. ADT-1: 15 days. | No |
| 5 | Death or disqualification | Section 139(8) + 141(4) | Board (fills casual vacancy) | ADT-1 (new auditor) | Board: 30 days of vacancy. ADT-1: 15 days. | No |
Scenario 1: Auditor Resignation (Most Common)
Step 1: Auditor submits resignation letter to the company. The resignation letter states the effective date and reasons.
Step 2: Auditor files Form ADT-3 with the company and ROC within 30 days. ADT-3 is filed by the auditor (not the company). It states reasons for resignation and any relevant facts. On MCA V3 portal: web-based form, requires SRN of original ADT-1.
Step 3: Company convenes Board meeting within 30 days of resignation. Board: takes note of resignation, identifies and appoints a new auditor to fill casual vacancy, obtains consent + Section 141 certificate from new auditor.
Step 4: Company files ADT-1 for the new auditor within 15 days of Board appointment.
Step 5: Company convenes EGM within 3 months of Board appointment. Shareholders approve the appointment of the new auditor. The new auditor holds office till the conclusion of the next AGM.
Penalty: Auditor who fails to file ADT-3 within 30 days: Rs 50,000 or remuneration of the auditor (whichever is less). Company: Section 147 penalties if ADT-1 not filed. For our auditor appointment guide (know more), see the detailed appointment process.
Scenario 2: Company Removes Auditor Before Term Expiry
This is the most procedurally complex scenario. The company wants to remove the auditor, but the auditor has not resigned.
Step 1: Board meeting - pass resolution to consider removal. Resolution authorises a designated person to file ADT-2 with the Central Government.
Step 2: File Form ADT-2 within 30 days of Board resolution. ADT-2 is an application to the Central Government (delegated to the jurisdictional Regional Director) seeking approval for removal. Includes: grounds for removal, auditor’s details, and details of other services provided by auditor.
Step 3: Give the auditor a reasonable opportunity of being heard. The auditor can submit a representation. Central Government considers both sides.
Step 4: Central Government grants or denies approval. If approved: proceed to Step 5. If denied: removal cannot proceed.
Step 5: Hold general meeting within 60 days of Central Government approval. Pass special resolution for removal of the auditor. File MGT-14 with ROC within 30 days.
Step 6: Intimate the removed auditor. Provide certified copy of resolution + Central Government approval.
Step 7: Appoint new auditor. Board or general meeting appoints new auditor. File ADT-1 within 15 days. For ROC compliance services (know more) covering the complete removal and replacement process, we handle all filings.
Scenario 3: Mandatory Rotation (Term Expires)
Applicable to: Listed companies + prescribed companies (unlisted public with paid-up capital > Rs 10 crore, private limited with paid-up capital > Rs 50 crore, companies with public borrowings > Rs 50 crore).
Step 1: Audit Committee (if applicable) recommends a new auditor 1 year before term expiry.
Step 2: Board approves the recommendation.
Step 3: At the AGM where the current auditor’s term expires, shareholders appoint the new auditor. Ordinary resolution. 5-year term.
Step 4: File ADT-1 within 15 days of AGM.
Step 5: Outgoing auditor completes handover. Working papers, correspondence, and pending matters transferred to the incoming auditor.
Note: Individual auditor = max 1 consecutive term of 5 years. Audit firm = max 2 consecutive terms of 5 years each (10 years). Cooling-off period: 5 years before reappointment in the same company.
Scenario 4: Non-Reappointment at AGM
The company decides not to reappoint the retiring auditor at the AGM. This is different from removal (no Central Government approval needed).
Step 1: A member of the company gives special notice (14 days before AGM) proposing that the retiring auditor shall not be reappointed.
Step 2: Company sends the notice to the retiring auditor. The auditor can make a representation in writing.
Step 3: At AGM, resolution is passed not to reappoint the retiring auditor and to appoint a new auditor.
Step 4: File ADT-1 for the new auditor within 15 days.
Step 5: File MGT-14 if special resolution was passed.
Scenario 5: Death or Disqualification (Casual Vacancy)
Step 1: Vacancy arises upon death or disqualification of the auditor. Disqualification under Section 141 (e.g., auditor becomes related to the company, convicted of fraud, indebted to the company).
Step 2: Board fills the casual vacancy within 30 days. Obtain consent + Section 141 certificate from new auditor.
Step 3: File ADT-1 for the new auditor within 15 days of Board appointment.
Step 4: New auditor holds office till the conclusion of the next AGM.
Note: ADT-3 is NOT required in case of death. The company simply proceeds with casual vacancy filling.

LLP Auditor Change: How It Differs
LLPs are governed by the LLP Act, 2008, not the Companies Act. The change process is significantly simpler:
- No ADT-1, ADT-2, or ADT-3 required.
- Auditor change: partners pass a resolution (in the LLP agreement or by mutual consent).
- New auditor: consent letter + engagement letter executed.
- No ROC filing specifically for auditor change (the change is reflected in Form 8 when the next annual financial statement is filed with the audited report by the new auditor).
- No Central Government approval needed for auditor removal in LLPs.

Step-by-Step: Outgoing-to-Incoming Auditor Handover Checklist
1. Resignation/removal formalities completed (ADT-3/ADT-2/resolution).
2. Outgoing auditor issues NOC (No Objection Certificate) to incoming auditor.
3. Working papers for the current and prior years transferred.
4. Pending observations, qualifications, and management letter points shared.
5. Tax and regulatory filings status briefed (audit report linked to AOC-4, ITR-6).
6. Incoming auditor reviews prior year financials and audit report before accepting appointment.
7. Incoming auditor issues consent letter + Section 141 certificate.
8. Company files ADT-1 for incoming auditor.
9. Engagement letter executed between company and incoming auditor.
10. Incoming auditor sends ‘communication letter’ to outgoing auditor as per SA 300/510 (Auditing Standards). For our statutory audit 2026 analysis (know more), see how the 2026 audit landscape affects handovers.
Common Mistakes in Auditor Change
Mistake 1: Confusing removal with non-reappointment. Removal (Section 140(1)) requires Central Government approval + special resolution. Non-reappointment at AGM (Section 140(4)) requires only special notice + ordinary resolution. Using the wrong process invalidates the change.
Mistake 2: Company filing ADT-3 instead of the auditor. ADT-3 must be filed by the auditor, not the company. The company cannot file ADT-3 on the auditor’s behalf.
Mistake 3: Not holding EGM within 3 months for resignation-based casual vacancy. When an auditor resigns, the Board appoints a replacement. But this appointment must be ratified by shareholders at an EGM within 3 months. Missing the EGM deadline is a compliance violation.
Mistake 4: Not obtaining NOC from outgoing auditor. While not legally mandatory, ICAI standards recommend that the incoming auditor communicate with the outgoing auditor. Not doing so raises professional conduct questions.
Mistake 5: Appointing a disqualified auditor as replacement. Section 141 disqualifications must be verified for the incoming auditor. Common disqualifications: related party, indebted to company, holding securities, convicted of fraud. For our Pvt Ltd compliance audit (know more), we verify auditor eligibility as part of the 10-point framework.
2026 Context: What’s New
| 2026 Change | Impact on Auditor Change | What to Do |
|---|---|---|
| ADT-3 updated: web-based + SRN linking (from 14 July 2025) | ADT-3 is now filed as a web-based form on MCA V3. Must include the SRN of the original ADT-1 that recorded the auditor’s appointment. Links resignation to original appointment record. | Ensure original ADT-1 SRN is available before filing ADT-3. If ADT-1 was not filed: file it first (with penalty). |
| ADT-1 mandatory for first auditor (from 14 July 2025) | If a first auditor resigns, the casual vacancy replacement also requires ADT-1. No ambiguity anymore. | File ADT-1 for every auditor appointment, including casual vacancy filling. |
| CCFS 2026 (Companies Compliance Facilitation Scheme) | One-time window to file overdue ADT-1, ADT-2, ADT-3, and MGT-14 at reduced penalties. | If you have pending auditor-change filings from prior years: use CCFS 2026 to regularise. |
| SEBI LODR for listed companies | Listed companies must disclose auditor resignation/removal to stock exchanges within 24 hours. Detailed reasons required. | Prepare disclosure before the change is effected. Coordinate with company secretary and compliance officer. |

Key Takeaways
There are five distinct scenarios for change of auditor: resignation, removal, mandatory rotation, non-reappointment, and death/disqualification. Each has a different procedure, different forms, and different timelines.
The most common scenario is resignation (ADT-3 by auditor + Board fills casual vacancy + EGM within 3 months + ADT-1 for new auditor). The most complex is removal before term (ADT-2 + Central Government approval + special resolution + ADT-1).
Four MCA forms may be involved: ADT-1 (new auditor appointment), ADT-2 (removal application), ADT-3 (resignation statement by auditor), and MGT-14 (special resolution). Each has strict timelines: 15 days (ADT-1), 30 days (ADT-2, ADT-3, MGT-14).
LLPs follow a simpler process: partner resolution + new engagement letter. No ADT forms. No ROC filing specifically for auditor change.
2026 updates: ADT-3 web-based with SRN linking, ADT-1 mandatory for all appointments (including first auditor), CCFS 2026 for overdue filings, and SEBI LODR disclosure for listed companies.
