Most directors assume the appointed Chartered Accountant will handle ADT-1 automatically once the AGM is done, the way an auditor handles their own engagement letter. That assumption is wrong, and it is the single biggest reason ADT-1 gets missed. The filing obligation sits with the company, specifically its directors, not with the auditor, and the auditor's only job here is to hand over a signed consent letter.
Knowing that distinction upfront changes how a Chennai company should plan the 15 days after its AGM. LegalX India takes the filing itself off your plate for ₹999, covering companies from the Ambattur Industrial Estate to those registered under Tambaram's own municipal corporation.
This is a Tamil Nadu wide obligation, not a Chennai specific quirk, but the practical difference for a Chennai company is which registrar receives the form. A company with its registered office anywhere from Guindy to the OMR corridor still routes its ADT-1 to ROC Chennai, and Tamil Nadu carries no local relaxation on the 15 day count regardless of the entity's size.
Is ADT-1 actually your company's responsibility, not your CA's?
If your company held an AGM where a statutory auditor was appointed or reappointed, ADT-1 applies, full stop. Private limited, public limited, OPC, Section 8 and Nidhi companies all carry this obligation whenever an auditor appointment happens at the AGM, regardless of the company's size or turnover.
There is no threshold below which a Chennai company is exempt. A dormant entity that appointed an auditor purely to satisfy the statutory audit requirement still owes ADT-1 within the same 15 days as an active trading company.
What should be sitting ready before we draft your ADT-1 paperwork?
Before ADT-1 can be prepared correctly, gather these:
- The board resolution appointing or reappointing the auditor
- A signed consent letter from the auditor confirming eligibility under the Companies Act
- The auditor's firm registration number and the period of appointment
- The company's CIN and the exact AGM date
- A valid Digital Signature Certificate for the filing director
A board resolution dated after the AGM is invalid for this purpose, so the resolution has to be passed on or before the AGM date itself, not drafted afterward to match it.
When does the 15 day clock start, and how do we track it?
ADT-1 is due within 15 days from the date of the AGM where the auditor was appointed. If your AGM is held on September 30, the last date for filing falls on October 15, and there is no extension available under normal circumstances.
The count starts from the AGM date itself, not from when the board resolution was signed or when the auditor's consent letter arrived. That makes the AGM date the only number that matters here, and it is worth writing down the moment the meeting concludes.
What does missing that 15 day window cost your company?
| Event | Timing |
|---|---|
| AGM where auditor is appointed | Day 0 |
| Deadline for ADT-1 filing | Within 15 days of AGM |
| Penalty starts | Day 16 onward |
| Maximum penalty | ₹12,000 per default |
The penalty runs at ₹300 a day until it hits the ₹12,000 ceiling, and it applies to the company as well as to officers in default, including the directors who signed off on the appointment. A month of delay already costs more than nine times what the filing itself would have cost through LegalX India.
Walk me through what happens after you contact LegalX India
- You share your CIN, AGM date and the auditor's registration details with us.
- We draft the board resolution and appointment letter, and check the consent letter's wording.
- Your director's Digital Signature Certificate gets attached to the completed ADT-1 form.
- We file on MCA V3, routed to ROC Chennai based on your company's registered address.
- You receive the SRN and a copy of the acknowledged form.
The whole cycle typically finishes in 3 to 5 working days, which leaves a comfortable margin inside the 15 day statutory window when you start early. Companies that share their AGM date and auditor details the same day the meeting concludes routinely see their SRN back well before the halfway point of the window. That leaves room to fix any document issue without risking the deadline itself.
Which Chennai companies tend to miss this filing?
An auto ancillary manufacturer in the Ambattur Industrial Estate is a repeat case. Production schedules take priority right after the AGM, and by the time anyone remembers the appointment needed a separate filing, several days of the 15 day window are already gone.
Companies registered under Tambaram's own municipal corporation show a different pattern. Founders there sometimes assume that because their trade licence and local registrations route through a separate civic body from Greater Chennai Corporation, their MCA filings work differently too. They do not. ADT-1 for a Tambaram registered company still goes to ROC Chennai on the same 15 day clock as anywhere else in Tamil Nadu. A commercial establishment owner in a similar position, running a shop or office out of Anna Nagar, tends to make the opposite mistake. They assume ADT-1 is somehow bundled into their Tamil Nadu Shops and Establishments filing, when the two have nothing to do with each other and run on completely separate calendars.
What does LegalX India do differently on a Chennai ADT-1 filing?
We have seen ADT-1 filings slip for one repeated reason: everyone in the room assumes someone else is handling it. The auditor assumes the company secretary has it. The director assumes the CA will file it as part of the audit engagement, and the 15 days disappear while that assumption sits unchallenged.
Our team takes direct ownership the moment you share your AGM date, drafts every supporting document to the standard ROC Chennai expects, and files through MCA V3 with an SRN you can check yourself.
