ADT-1 Filing Online

ADT-1 filing is the company's notice to the Registrar of Companies that an auditor has been appointed, filed on MCA21 under Section 139 of the Companies Act, 2013 within 15 days. StampMitra helps you prepare the resolution and the intimation to the auditor, checks the auditor's consent and certificate, and files the form for you.

What ADT-1 is and the law behind it

Form ADT-1 is the notice a company gives to the Registrar of Companies (ROC) when it appoints an auditor. The basis is Section 139 of the Companies Act, 2013 and Rule 4(2) of the Companies (Audit and Auditors) Rules, 2014, which says the notice goes in Form ADT-1 under the fourth proviso to sub-section (1) of section 139. The company files it on MCA21; the auditor does not.

Who files ADT-1

Any company that appoints an auditor, whatever its type.

  • Companies appointing at the AGM
  • Casual vacancy appointments
  • Section 8 companies
  • OPCs and small companies
  • Not ADT-1: LLPs
  • Not ADT-1: auditor resignation

ADT-1 for the first auditor of a new company

A new company's Board appoints the first auditor within 30 days of incorporation. Rule 4(2) refers to appointments under Section 139(1), so it does not expressly mention a first auditor appointed by the Board under Section 139(6).

The normal fee depends on the company's nominal share capital.

  • Below ₹1 lakh: ₹200
  • ₹1 lakh to under ₹5 lakh: ₹300
  • ₹5 lakh to under ₹25 lakh: ₹400
  • ₹25 lakh to under ₹1 crore: ₹500
  • ₹1 crore or more: ₹600
  • Company without share capital: ₹200

Frequently asked questions

Who files ADT-1?

The company files it, signed with a DSC by a director, manager, CS, CEO or CFO whom the Board has authorised. The auditor does not file it.

When must ADT-1 be filed?

Within 15 days of the meeting in which the auditor is appointed (Rule 4(2)). For appointments made other than at a meeting, we count 15 days from the appointment, which is practice and not the wording of the rule.

Is ADT-1 needed for the first auditor?

The Board must appoint the first auditor within 30 days of incorporation. Whether ADT-1 is expressly required for that appointment is not settled, because Rule 4(2) refers to Section 139(1). Filing it is widely done and we recommend it; confirm with your CA.

What is the government fee?

₹200 to ₹600 depending on nominal share capital, and ₹200 for a company without share capital, under the 2018 fee table. The same gazette says no fee is payable for some small companies incorporated on or after 26 January 2018; we confirm how it applies to yours. The professional fee is separate.

Is ADT-1 filed every year?

No. It is filed when an appointment, reappointment or casual-vacancy appointment is made. A 5-year term needs one filing, at the AGM that appoints the auditor.

Does an OPC file ADT-1?

Yes. An OPC appoints an auditor and files ADT-1, although it holds no AGM and is exempt from mandatory auditor rotation. With no meeting, we count the 15 days from the appointment date.

What if the auditor changes in the middle of the term?

A resignation or removal involves separate steps for the outgoing auditor and a fresh appointment, which is then reported in ADT-1. Talk to us before the change so the sequence is right.

What happens if I file late?

An additional fee applies, from 1 times the normal fee for up to 15 days of delay to 12 times beyond 180 days. A late ADT-1 can also hold up AOC-4.

Does a Section 8 company file ADT-1?

Yes. The same rule applies.

Does an LLP file ADT-1?

No. ADT-1 is a Companies Act form. LLP accounts follow the LLP Act and Form 8.
