Audit of Government Companies under the Companies Act (CA Final Audit)

Updated 5 October 2026 · Fact-checked

A government company is one where the Central or State Governments hold at least 51% of paid-up capital. Its statutory auditor is appointed by the CAG, not by members. The auditor follows CAG directions under Section 143(5), and the CAG may conduct supplementary audit and comment on the auditor's report within 60 days of receiving it.

Understand Audit of Government Companies under Companies Act

A government company is defined in Section 2(45) of the Companies Act, 2013. It is a company in which at least 51% of the paid-up share capital is held by the Central Government, or by one or more State Governments, or partly by the Central Government and partly by State Governments. A subsidiary of a government company is also a government company.

For an ordinary company, members appoint the auditor at the AGM. A government company is different because public money is involved. So the Comptroller and Auditor General of India (CAG) appoints the statutory auditor. Section 139(5) applies this to government companies and to any other company owned or controlled, directly or indirectly, by the Central or State Governments. Section 139(7) covers the first auditor of a government company.

The CAG does not stop at the appointment. Under Section 143(5), the CAG directs the auditor on the manner in which the accounts are to be audited. The auditor must report on these directions and send a copy of the audit report to the CAG.

The CAG then has a second layer of control under Section 143(6). Within 60 days from receipt of the audit report, he may order a supplementary audit by persons he authorises. Within the same 60 days he may also comment upon, or supplement, the auditor's report. The company must send these comments to every person entitled to copies of the financial statements and place them before the AGM at the same time and in the same manner as the audit report. Section 143(7) adds a power to order a test audit.

Think of it as two audits. The chartered accountant does the statutory audit. The CAG then reviews it and adds comments. Exam questions test who appoints, in what time, and what the CAG can do afterwards.

Key rules to remember

Government company (Section 2(45))
Government holding ≥ 51% of paid-up share capital (Central, State, or both together); subsidiary of a government company is also a government company
The test is not less than 51%; a holding of exactly 50% does not qualify. Holdings of Central and State Governments can be added together.
Subsequent auditor (Section 139(5))
Appointed by the CAG within 180 days from the commencement of the financial year; holds office till the conclusion of the AGM
Applies to government companies and other companies owned or controlled by Central or State Governments. Members do not appoint.
First auditor of a government company (Section 139(7))
CAG within 60 days from the date of registration → if CAG fails, Board within the next 30 days → if Board fails, members at an EGM within 60 days
The Board and members act only as fallbacks. The CAG has the first right.
CAG directions (Section 143(5))
CAG directs the manner of audit → auditor complies and reports on the directions → copy of audit report goes to the CAG
The auditor reports on these directions in the report on other legal and regulatory requirements.
Supplementary audit and comments (Section 143(6))
Within 60 days from receipt of the audit report, the CAG may conduct a supplementary audit and comment upon or supplement the audit report
The Act gives the CAG this right within 60 days from receipt of the audit report. The company sends the comments to every person entitled to the financial statements and places them before the AGM at the same time and in the same manner as the audit report. The Act does not state a consequence for comments made after the 60 days, so do not invent one.
Test audit (Section 143(7))
CAG may, if he considers it necessary, order a test audit of the company's accounts by order
Section 19A of the CAG's (Duties, Powers and Conditions of Service) Act, 1971 applies to the report of such test audit.

How to solve Audit of Government Companies under Companies Act questions

Use this method for any question on audit of government companies. Write the answer in provision, facts, conclusion form.

  1. 1Check whether the company is a government company. Add Central and State holdings. Check for 51% or more, or whether it is a subsidiary of a government company.
  2. 2Identify the stage: first auditor or subsequent auditor. First auditor falls under Section 139(7). Subsequent auditor falls under Section 139(5).
  3. 3State who appoints and the time limit. For subsequent auditors it is the CAG within 180 days from the start of the financial year. For the first auditor, apply the 60-day, 30-day and 60-day chain.
  4. 4If the question is about the audit itself, state that the CAG may give directions under Section 143(5). The auditor must comply and report on them and send a copy of the report to the CAG.
  5. 5If the question is about CAG's review, state Section 143(6): within 60 days from receipt of the audit report, the CAG may order a supplementary audit and comment upon or supplement the report. Add that the company sends the comments to every person entitled to the financial statements and places them before the AGM.
  6. 6Mention test audit under Section 143(7) if the CAG orders a test audit.
  7. 7Apply the facts of the case to the rule. Say who acted correctly or wrongly. If comments come after 60 days, say they fall outside the 60-day period in Section 143(6). Do not state a consequence that the Act does not give.
  8. 8Close with a one-line conclusion that answers the exact question asked.

Quickest way: Who, when, what after: the three-question check

When to use it: Use this for case-scenario MCQs and short written parts where you have only a few minutes.

  1. Who appoints? If it is a government company, the CAG appoints, not members or the Board (except as fallback for the first auditor).
  2. When? 180 days from the start of the financial year for subsequent auditors. 60 days from registration for the first auditor.
  3. What after? The CAG can direct the audit under Section 143(5). Within 60 days of receiving the audit report, he can order a supplementary audit and comment under Section 143(6). He can order a test audit under Section 143(7).
  4. Pick the option that matches all three. Reject any option that gives members the first right of appointment.

Common mistakes in Audit of Government Companies under Companies Act

  • Saying the members appoint the auditor of a government company at the AGM.

    Students carry over the rule for ordinary companies under Section 139(1).

    Fix: For government companies, the CAG appoints under Section 139(5). Members or the Board come in only as fallbacks for the first auditor under Section 139(7).

  • Treating a company with exactly 50% government holding as a government company.

    Students remember 'half' instead of the actual threshold.

    Fix: The threshold is not less than 51% of paid-up capital. Add Central and State holdings before testing.

  • Missing that a subsidiary of a government company is also a government company.

    Students look only at the direct shareholding by the government.

    Fix: Section 2(45) includes subsidiaries of government companies. The CAG appoints the auditor for them too.

  • Mixing up the 180-day, 60-day and 30-day periods.

    Several time limits appear in Sections 139 and 143 and they look similar.

    Fix: Learn them by stage. Subsequent auditor: 180 days from start of the year. First auditor: 60 days from registration, then 30 days for the Board, then 60 days for members. CAG supplementary audit and comments: 60 days from receipt of the audit report.

  • Writing that CAG comments change or replace the statutory auditor's report.

    The words 'comment upon or supplement' are read as 'override'.

    Fix: The CAG comments on or supplements the report. The auditor's report stays the auditor's own. The comments are placed before the AGM along with it.

  • Confusing supplementary audit with test audit.

    Both are CAG powers and both come after the statutory audit.

    Fix: Supplementary audit is under Section 143(6) and ties to commenting on the audit report. Test audit is under Section 143(7) and is ordered by the CAG when he considers it necessary.

  • Writing that CAG comments received after 60 days are invalid or can simply be ignored.

    Students treat the 60-day period as a hard bar that wipes out the comments.

    Fix: Say that the comments fall outside the 60-day period in Section 143(6). Do not claim they are void, open to challenge or ignorable, because the Act does not state a consequence.

Worked examples

Example 1

Alpha Ltd has paid-up capital held 30% by the Central Government and 22% by a State Government. Its subsidiary, Beta Ltd, has its AGM coming up. The members of Beta Ltd propose to reappoint a CA firm as the statutory auditor for the new year. Is this proper?

Show the solution
  1. Test Alpha Ltd. Central 30% + State 22% = 52%, which is at least 51%. So Alpha Ltd is a government company under Section 2(45).
  2. Beta Ltd is a subsidiary of a government company. Under Section 2(45), a subsidiary of a government company is also a government company.
  3. Because Beta Ltd is a government company, Section 139(5) applies. The CAG appoints the auditor, within 180 days from the commencement of the financial year.
  4. The members therefore have no power to appoint or reappoint the auditor at the AGM.
  5. Conclusion: the proposal is not proper. The CA firm can act as auditor only if the CAG appoints it.

Answer: Not proper. Alpha Ltd is a government company (52%), and Beta Ltd, as its subsidiary, is also one. The CAG appoints the auditor under Section 139(5), so the members cannot reappoint the firm.

Example 2

Gamma Ltd, a government company, received the statutory auditor's report on 1 August 2026. The CAG's office sent comments on the report to the company on 15 October 2026. The directors say the comments are late and can be ignored. Also, the auditor says his report cannot be touched by the CAG. Advise.

Show the solution
  1. Recall Section 143(6): within 60 days from receipt of the audit report, the CAG may conduct a supplementary audit and comment upon or supplement the report.
  2. Count 60 days from 1 August 2026. It ends on 30 September 2026.
  3. The comments are dated 15 October 2026, which is after the 60-day period. So the directors are right that the comments fall outside the 60-day period in Section 143(6).
  4. However, the directors cannot conclude that the comments can be ignored. The Act does not state what follows when comments come after the 60 days, so you should not claim that they are void or ignorable.
  5. The auditor's argument is wrong. The CAG has the power to comment upon or supplement the audit report. This does not change the auditor's own report, but the power exists.
  6. Where comments are issued, the company must send them to every person entitled to the financial statements and place them before the AGM at the same time and in the same manner as the audit report.
  7. Conclusion: the comments of 15 October 2026 fall outside the 60-day period, but the Act is silent on the consequence. The directors should not simply treat them as ignorable, and the auditor cannot claim that the CAG lacks power to comment.

Answer: The 60-day period ended on 30 September 2026, so comments sent on 15 October 2026 fall outside the period in Section 143(6). The Act is silent on the consequence, so the directors cannot safely treat the comments as ignorable. The auditor is wrong that the CAG cannot comment, because the CAG has the power to supplement or comment on the report.

Exam tips

  • Write the section numbers with the rule: 139(5), 139(7), 143(5), 143(6), 143(7). Examiners reward a correct section tied to the right power.
  • In case scenarios, always start by testing the 51% threshold or the subsidiary link. Most MCQs hide the trap there.
  • Keep the three time limits in a small table in your memory: 180 days, 60 days, 60 days for CAG comments. Write the number with its stage.
  • If CAG comments come after 60 days, write that they fall outside the 60-day period in Section 143(6). Do not add a consequence the Act does not state, and do not write that they can be ignored.
  • For a written answer, structure as provision, facts, conclusion. Do not leave out the final one-line conclusion.
  • Link this topic to the CAG's role in the related topics on PSU audit. A short reference to the constitutional role of the CAG adds depth.
