To appoint an auditor in Kolkata, the board appoints a practising CA within 30 days of incorporation (later auditors are appointed at the AGM for five years), and the company files Form ADT-1 within 15 days of that meeting with ROC Kolkata-I for a Kolkata-district office or ROC Kolkata-II for the rest of West Bengal. The MCA fee is Rs 200 to Rs 600 by share capital. Appoint your statutory auditor and file Form ADT-1 with ROC Kolkata-I or ROC Kolkata-II, depending on district. Every company registered under the Companies Act, 2013 must have an auditor in place, and the appointment is notified to the registrar that holds your file. Professional fee from Rs 2,699, excluding GST.
| Item | Position for Kolkata |
|---|---|
| Filing authority | ROC Kolkata-I / Kolkata-II |
| Form | ADT-1 |
| Governing provision | Section 139, Companies Act, 2013 |
| First auditor deadline | Board appoints within 30 days of incorporation |
| If the board fails | Members appoint within 90 days at an extraordinary general meeting |
| Subsequent auditor | Appointed at AGM for five consecutive years |
| ADT-1 deadline | Within 15 days of the meeting making the appointment |
Under Section 139 of the Companies Act, 2013, every company must appoint a statutory auditor and notify the Registrar of Companies in Form ADT-1. For a company with its registered office in Kolkata, that notification goes to ROC Kolkata-I or ROC Kolkata-II, depending on district. The registrar is not a formality here - it is the office that holds your statutory file, raises any objection on the appointment, and against which any subsequent removal or resignation is recorded.
Recent change: ROC Kolkata was split into two offices on 16 February 2026. Kolkata-I covers the district of Kolkata and the State of Sikkim. Kolkata-II covers the rest of West Bengal. Both sit in Kolkata, but they are separate registrars with separate files.
Registered office location determines the registrar. For Kolkata:
| Registered office | Registrar | Regional Director |
|---|---|---|
| Kolkata district | ROC Kolkata-I, Kolkata | RD Eastern Region, Kolkata |
| West Bengal outside Kolkata district, including Salt Lake, Rajarhat, Howrah and the 24 Parganas | ROC Kolkata-II, Kolkata | RD Eastern Region, Kolkata |
| Sikkim | ROC Kolkata-I, Kolkata | RD Eastern Region, Kolkata |
LLPs do not file ADT-1. An LLP needs its accounts audited only where turnover exceeds Rs 40 lakh and contribution also exceeds Rs 25 lakh, and the appointment is not notified in ADT-1. See LLP registration in Kolkata for the LLP side.
The proposed auditor must be a practising chartered accountant or firm, and must not attract any disqualification under Section 141.
Written consent and the Section 141 certificate are obtained before the board meets. Filing without these is a common cause of objection.
The board passes a resolution appointing the auditor. For a first auditor this must happen within 30 days of incorporation.
The company formally intimates the appointment to the auditor.
ADT-1 is filed within 15 days of the appointing meeting and routed to ROC Kolkata-I / Kolkata-II. The filing is made by the company, not the auditor.
ROC Kolkata-I / Kolkata-II records the appointment against your file. Any deficiency is raised as a resubmission against this office.

A Kolkata company incorporated in the current financial year appointed its auditor at day 34, four days past the board window under Section 139(6). The appointment then had to move to the members through an extraordinary general meeting within 90 days rather than sitting with the board. The ADT-1 was ultimately filed with ROC Kolkata-I / Kolkata-II, but the company carried an avoidable EGM and a delayed first-year audit start.
Illustrative scenario based on typical file patterns. Not a named client engagement.

ROC Kolkata-I or ROC Kolkata-II, depending on district. ROC Kolkata was split into two offices on 16 February 2026. Kolkata-I covers the district of Kolkata and the State of Sikkim. Kolkata-II covers the rest of West Bengal. Both sit in Kolkata, but they are separate registrars with separate files.
The company files it. The auditor supplies written consent and the Section 141 eligibility certificate, but the filing obligation sits with the company.
The board must appoint within 30 days of incorporation. If it does not, the members must appoint within 90 days at an extraordinary general meeting.
No. ADT-1 is a Companies Act form. An LLP needs an audit only where turnover exceeds Rs 40 lakh and contribution also exceeds Rs 25 lakh, and even then the appointment is not notified in ADT-1.
An additional fee of 2 times the normal fee applies for a delay of up to 30 days, rising in steps to 12 times beyond 180 days. Continued default also exposes the company and its officers under Section 147, so a late form should be filed as soon as the delay is noticed rather than left for the annual filing.
No. Any practising chartered accountant or CA firm in India can be appointed, as long as they give written consent and a Section 141 certificate confirming they are eligible and not disqualified. Location only decides which registrar receives the ADT-1: the company's registered office address picks ROC Kolkata-I or Kolkata-II, not the auditor's office.
It depends on the company's nominal share capital: Rs 200 below Rs 1 lakh, Rs 300 from Rs 1 lakh to Rs 4,99,999, Rs 400 from Rs 5 lakh to Rs 24,99,999, Rs 500 from Rs 25 lakh to Rs 99,99,999 and Rs 600 at Rs 1 crore or more. A late ADT-1 adds 2 to 12 times that fee depending on the delay. There is no West Bengal stamp duty on ADT-1.
No. ADT-1 is filed when an auditor is appointed or reappointed: the first auditor, the auditor appointed at an AGM for a five-year term, a second term, or a casual vacancy filled by the board or members. A company whose auditor is part-way through a five-year term has no ADT-1 to file for that year, though the auditor still audits every year's accounts.
For a typical company with Rs 1 lakh nominal capital filing on time, the MCA fee is Rs 300 and our professional fee starts at Rs 2,699 plus GST, covering the consent, the Section 141 certificate format, the board resolution, the intimation letter and the filing. If the form is 45 days late, the additional fee is 4 times the normal fee, Rs 1,200 more.
