The appointment of the first auditor is an important statutory compliance for every newly incorporated non-Government company. However, one question continues to create confusion: Is Form ADT-1 mandatory for appointment of the first auditor by the Board?

The confusion increased after the MCA introduced a revised Form ADT-1 from 14 July 2025, containing an option specifically referring to the “First Auditor by Board/Members”. If you are looking for a tax consultant near me, company registration consultant near me, or professional compliance support in Ghaziabad, Noida, Delhi NCR and nearby areas, understanding the distinction between the statutory provision and the e-form requirement is important.

The key issue is that the existence of a filing option in an MCA e-form does not, by itself, create a substantive statutory obligation. The legal position therefore needs to be examined by reading Section 139, the Companies (Audit and Auditors) Rules, 2014 and the changes made to Form ADT-1 together.

Latest Update – 2026

The MCA notified the Companies (Audit and Auditors) Amendment Rules, 2025 through G.S.R. 359(E) dated 30 May 2025, with the revised forms becoming effective from 14 July 2025.

The revised Form ADT-1 now contains a field for reporting “First Auditor by Board/Members”. This has created an important practical distinction between what the electronic form permits and what the substantive provisions expressly require.

As of 2026, the professional position reflected in the verified material is that Section 139(6) does not expressly prescribe filing of ADT-1 for the first auditor appointed by the Board. ICSI has also represented to MCA seeking clarification on the applicability of ADT-1 to first auditor appointments and requesting that system validations remain aligned with the statutory provisions.

Therefore, while the legal mandate remains subject to clarification, filing ADT-1 for first auditor appointments made on or after 14 July 2025 is considered the safer and more prudent compliance approach.

Legal Position

Section 139(6) of the Companies Act, 2013 separately governs appointment of the first auditor of a non-Government company. Under this provision, the Board is required to appoint the first auditor within 30 days of incorporation. If the Board fails to appoint the auditor within that period, the members are required to take the necessary action in accordance with the statutory framework.

The express filing obligation for Form ADT-1 flows from the fourth proviso to Section 139(1) read with Rule 4(2) of the Companies (Audit and Auditors) Rules, 2014. Historically, this framework dealt with appointments of auditors by members at an AGM or EGM and did not contain a corresponding express filing requirement for the first auditor appointed by the Board under Section 139(6).

This distinction became important following the revised Form ADT-1 introduced from 14 July 2025.

The revised form now includes an option to report “First Auditor by Board/Members”. In practical terms, the MCA system now accommodates reporting of first auditor appointments through ADT-1. However, the substantive provisions themselves have not, on the verified position, expressly created a corresponding filing obligation under Section 139(6).

ICSI has represented to MCA regarding this issue. Its position is that statutory filing requirements should flow from the applicable legal provisions and that an electronic form or system validation should not independently impose an obligation beyond the statute.

Accordingly, the legal position as of 2026 contains an important nuance: the revised ADT-1 form can be used for first auditor appointments, but the form itself does not automatically establish a substantive statutory mandate where the underlying provision does not expressly prescribe such filing.

For appointments made before 14 July 2025, filing ADT-1 for the first auditor was not mandated under the then-existing substantive provisions. For appointments made on or after 14 July 2025, filing ADT-1 is considered the safer and expected compliance route in view of the revised form design and practical ROC expectations, pending formal clarification or amendment by MCA.

Practical Explanation: What Should a Company Do?

The easiest way to understand the issue is to distinguish law from practical compliance.

For example, suppose a private limited company was incorporated on 1 August 2026. The Board appoints the first auditor within the prescribed period. Even though Section 139(6) does not expressly state that ADT-1 must be filed for this appointment, the revised ADT-1 provides a specific reporting option for the first auditor.

In such a situation, avoiding the form merely because the statute does not expressly mandate it may create an unnecessary practical compliance question later. Therefore, filing the revised ADT-1 can be considered a prudent compliance measure.

Compliance Process for First Auditor Appointment

A company should follow a properly documented process rather than focusing only on the e-form.

Step 1 – Check the statutory timeline:
For a non-Government company, the Board should appoint the first auditor within 30 days of incorporation.

Step 2 – Obtain the auditor's consent and eligibility confirmation:
The proposed auditor should provide the necessary consent and confirmation of eligibility before appointment.

Step 3 – Pass the Board resolution:
The company's Board should formally record the appointment through an appropriate Board resolution.

Step 4 – Inform the auditor:
The appointed auditor should be formally informed about the appointment and relevant engagement details.

Step 5 – Maintain statutory records:
Keep the Board resolution, auditor consent, eligibility documents, appointment records and related correspondence in the company's records.

Step 6 – Consider ADT-1 filing:
For first auditor appointments made on or after 14 July 2025, filing the revised ADT-1 is the prudent course in view of the revised form and practical ROC expectations, even though the substantive statutory mandate remains unclear.

Step 7 – Monitor MCA clarification:
Companies and professionals should remain alert for any future MCA clarification, circular, notification or amendment that settles the issue.

Common Compliance Mistake

A common mistake is to assume that because MCA's portal accepts a particular form, the underlying legislation must necessarily make that filing compulsory.

An e-form is a mechanism for submitting information. The substantive obligation should be traced back to the Companies Act and applicable Rules.

At the same time, companies should not ignore practical compliance merely because a strict statutory mandate is debatable. Where an available filing can reduce future questions regarding auditor appointment records, prudent compliance may be commercially sensible.

This is particularly relevant for newly incorporated businesses that are also completing company registration, GST registration and other post-incorporation compliances.

FAQ

1. Is ADT-1 mandatory for the first auditor appointed by the Board?

Section 139(6) does not expressly mandate ADT-1 filing for the first auditor appointed by the Board. However, after 14 July 2025, the revised form specifically accommodates first auditor reporting, making filing the safer and prudent approach pending MCA clarification.

2. What changed in ADT-1 from 14 July 2025?

The revised ADT-1 introduced from 14 July 2025 contains a field for “First Auditor by Board/Members”. This allows first auditor appointments to be reported through the form.

3. Does the revised form itself create a legal obligation?

No. The presence of a field or filing option in an electronic form does not, by itself, create a substantive statutory obligation. The underlying requirement must be traced to the Companies Act and applicable Rules.

4. What about first auditor appointments made before 14 July 2025?

For appointments made before 14 July 2025, ADT-1 was not mandated under the then-existing substantive provisions for first auditor appointments under Section 139(6). Historical cases should nevertheless be examined based on the law and compliance requirements applicable at that time.

5. Should a company file ADT-1 after 14 July 2025?

As a practical matter, filing ADT-1 is recommended for first auditor appointments made on or after 14 July 2025 because the revised form specifically provides for such reporting and filing is the safer route while the legal position awaits clarification.

6. What documents should be maintained?

The company should maintain the Board resolution, auditor's consent, eligibility confirmation, appointment communication and relevant internal records. Where ADT-1 is filed, the filing acknowledgement should also be preserved.

7. Has ICSI sought clarification from MCA?

Yes. ICSI has represented to MCA regarding the applicability of ADT-1 to first auditor appointments and has highlighted the difference between the statutory provisions and the revised e-form design.

Conclusion

The answer to whether Form ADT-1 is mandatory for the first auditor is not simply yes or no.

Legally, Section 139(6) separately governs the appointment of the first auditor by the Board, and there is no express statutory mandate identified in the verified position requiring ADT-1 for such an appointment. The express ADT-1 filing framework is associated with the fourth proviso to Section 139(1) read with Rule 4(2).

However, the position changed from a practical perspective after 14 July 2025, when the revised ADT-1 introduced a specific option for reporting the first auditor by the Board/Members. Until MCA provides a definitive clarification or makes an appropriate amendment, companies should consider filing ADT-1 for first auditor appointments made on or after that date as a matter of prudence.
