A resignation vacancy needs two different decisions
Section 139(8)(i) of the Companies Act, 2013 requires the covered non-CAG auditor vacancy to be filled by the Board within thirty days. Where caused by resignation, the appointment also needs company approval at a general meeting convened within three months of the Board recommendation. Checked on 28 October 2026, this guide focuses on those vacancy calendars. It does not treat retirement, removal or the first auditor's appointment as interchangeable with a casual vacancy. ICSI official Act text: Companies Act section 139(8) and (11).
Establish the actual vacancy date and cause
Retain the resignation or other event evidence and resolve its effective date before calculating a deadline. Receipt, a future effective resignation and a Board meeting can occur on different dates. The examples stipulate an already legally established vacancy date. A Board should not postpone the start merely by noting an earlier event later. Conversely, a planned retirement at the end of a normal term requires its own appointment analysis rather than an invented resignation event. ICSI official Act text: Companies Act section 139(8) and (11).
Run the Board and member calendars independently
For a non-CAG resignation case, record the Board's actual recommendation date and the general meeting date. Thirty days is a day-count period; three months is a calendar-month period. Waiting until the end of the member window to make the Board appointment can miss the earlier duty. A general meeting that is merely proposed in a draft calendar is not evidence of the required approval. Ensure the meeting and its notice/procedures satisfy their independently applicable rules; this article does not calculate a universal notice period. ICSI official Act text: Companies Act section 139(8) and (11).
Use the CAG branch only where the statutory population applies
Section 139(8)(ii) gives CAG thirty days for the covered vacancy. If CAG does not fill it in that period, the Board has the next thirty days. Do not run the Board's fallback period concurrently with the first CAG period. Determine whether the accounts are subject to an auditor appointed by CAG from the actual statutory position. Government involvement in a transaction alone should not replace that legal classification. ICSI official Act text: Companies Act section 139(8) and (11).
Retain eligibility and Audit Committee evidence
Where section 177 requires an Audit Committee, section 139(11) requires its recommendations to be taken into account for appointments including casual vacancies. Maintain the candidate's consent, eligibility and appointment records required under the independently applicable auditor provisions. A completed date spreadsheet cannot cure a disqualified auditor or missing approval. Related resignation and Registrar filings need their own current form and deadline review; they should not be presumed completed by an internal Board resolution. ICSI official Act text: Companies Act section 139(8) and (11).
Reconcile tenure and handover
For the covered non-CAG vacancy appointment, subsection (8)(i) states office continues until conclusion of the next AGM. Do not describe that vacancy filling as an automatic fresh five-year appointment. Track any later AGM action separately and organise predecessor communication, records and reporting-period responsibilities under applicable professional requirements. The calendar models exclude the stipulated trigger day when adding elapsed days and assume no special rule or order changes the dates; they are planning illustrations, not a conclusion about an actual disputed effective date. ICSI official Act text: Companies Act section 139(8) and (11).

Six worked illustrations
All facts and amounts below are fictional. Assumptions describe the model, not additional statutory rules.
Illustrative example 1: Board thirty-day period
Assume a non-CAG vacancy occurs on 1 June 2026. Thirty elapsed days give 1 July 2026. A Board action on 2 July is day 31, one day beyond this isolated model window.
Illustrative example 2: Resignation member approval calendar
Assume the Board recommends the replacement on 20 June 2026. Three calendar months lead to 20 September 2026. The separate thirty-day Board obligation still depends on the vacancy date.
Illustrative example 3: Calendar months are not ninety days
Assume recommendation on 1 July 2026. Three calendar months end on 1 October 2026, an elapsed 92 days. Substituting ninety days gives 29 September, two days earlier than this model calendar-month date.
Illustrative example 4: CAG fallback sequence
Assume a covered CAG vacancy on 1 August 2026 and no CAG appointment in the initial period. Thirty elapsed days give 31 August; the next thirty-day Board period then ends on 30 September. Running both periods from 1 August would wrongly compress the stated sequence.
Illustrative example 5: An early Board recommendation does not extend the first deadline
Assume vacancy on 1 May 2026 and Board recommendation on 15 May. The Board model deadline is 31 May, while the member-approval calendar is 15 August. These dates are 76 days apart; they govern separate acts.
Illustrative example 6: Measure time actually available
Assume vacancy on 1 September 2026 and Board appointment on 25 September, day 24. Six elapsed days remain to the model day-30 date, 1 October. A late internal discovery does not automatically restart the original period.

Sixteen practitioner FAQs
1. Does every auditor change create a casual vacancy?
No. Classify the actual event first.

The Board within the specified thirty days.
5. What additional step applies to resignation?
The stated company approval at a general meeting.
6. What date anchors that three-month window?
The Board recommendation date.

10. When does the Board fallback follow?
In the next thirty days if CAG has not filled it.

Section 139(11) requires its recommendations to be taken into account.
13. Can an ineligible candidate be appointed just because time is short?

The stated non-CAG tenure ends at conclusion of the next AGM.
16. What belongs in the final file?
Effective-date, authority, eligibility, resolutions, meeting and filing evidence.
