Government audit examines public money for the legislature, and covers regularity, propriety and value for money as well as the accounts. Private sector audit examines a company's financial statements for its owners and gives an opinion on whether they are true and fair. The auditor, the audience and the questions are all different.
Last reviewed: 17 October 2026. Facts checked. We opened the cag.gov.in pages on Articles 148 to 151, the cag.gov.in page on the audit provisions of the 1971 Act (Sections 13 to 21, 23 and 24), and the page for CAG's Auditing Standards, 2017. We also ran a search on Companies Act section 143. We did not open ICAI's Standards on Auditing for this post, so the private-sector column rests on the general structure of a statutory audit as described in our own earlier posts.
The short comparison
| Government audit (CAG) | Private sector audit (statutory) | |
|---|---|---|
| Who audits | The CAG and the Indian Audit and Accounts Department | A chartered accountant or firm |
| Who appoints | The CAG's office is created by Article 148 and the President appoints the CAG | Members (shareholders) appoint the auditor, with the board; for government companies the CAG appoints |
| Who receives the report | The legislature, through the President or Governor (Article 151) | Members of the company, and the ROC and others by filing |
| Main legal source | Constitution, 1971 Act, CAG's Auditing Standards | Companies Act, 2013 and ICAI Standards on Auditing |
| Core question | Was public money spent lawfully, properly and with value? | Do the financial statements give a true and fair view? |
| Output | Reports with findings and recommendations | An auditor's report with an opinion |
Who is the audit for
A private audit serves shareholders and others who rely on the financial statements. The client is the company.
A government audit serves the legislature, which approved the spending. The CAG's reports are laid before Parliament or the State Legislature. Background on how this works is in the CAG's role and powers.
What is tested
A private statutory audit centres on financial statements. The auditor gathers evidence on misstatement and gives an opinion. See statutory audit explained.
Government audit goes wider. A CAG page lists tests under Section 13: audit against provision of funds, regularity, propriety, efficiency-cum-performance (value for money), and systems. Propriety asks about wisdom, faithfulness and economy, which an opinion on financial statements does not.
Independence works differently
In the private sector, independence rests on the Companies Act and the ICAI Code of Ethics, with rules on rotation and disqualification. See auditor appointment, tenure and rotation.
In government audit, it is built into Article 148: removal on the grounds and by the procedure for a Supreme Court judge, protected pay, and a bar on later government office.
Sampling and selection
A private audit usually covers every company it is engaged for, each year. The CAG's coverage is chosen differently. A CAG FAQ page says audit offices prepare an annual plan from a risk analysis using factors like expenditure, internal controls, past findings and schemes. Not every unit is audited each year to the same depth.
What happens with findings
A private auditor reports to members and may qualify the opinion. Management may adjust the statements before signing.
In government audit, findings go through inspection reports and draft paragraphs. The department has six weeks to reply, and the final report is laid before the legislature. Committees then examine it. See how CAG reports are prepared.
Where the two meet
Government companies sit in both worlds. The CAG appoints the statutory auditor and can supplement the audit report. For government companies, the Companies Act routes the audit through the CAG, which we cover in a later post in this series.
Skills that carry across
An auditor who moves between the two will find the basics the same: understand the entity, assess risk, gather evidence, form a view. What changes is the benchmark. In government audit it is often a rule, sanction or scheme guideline. In private audit it is the reporting framework.
Reporting style
A private audit report is short and standard. It states an opinion, the basis for it, and key audit matters where they apply. A government audit report reads more like a narrative. It sets out scope, criteria, findings, causes and recommendations, and gives space to the department's reply. The audience is a legislative committee, so the report is written to be questioned in a hearing.
Remedies and consequences
A private auditor's main lever is the opinion. A qualified or adverse opinion tells members and others that the statements cannot be fully relied on. In government audit, the report itself does not order action. The legislature's committees examine it, and the government replies with action taken notes. The consequences, if any, follow from that process and from the governing law.
A quick test
Ask who the report is addressed to. If the answer is shareholders and lenders, you are in private sector territory. If the answer is the legislature, you are in government audit.
Frequently Asked Questions
Is government audit the same as statutory audit?
No. A statutory audit is an audit of a company's financial statements under the Companies Act. Government audit is carried out for the legislature and covers wider questions like propriety and value for money.
Who audits government departments?
The CAG, through the Indian Audit and Accounts Department, under the Constitution and the 1971 Act.
Do private companies face a CAG audit?
Not by default. Government companies do, through the CAG's role in appointing auditors and supplementary audit.
Which is wider in scope?
Government audit. The CAG's tests include propriety and value for money, not only fair presentation.
Do the same auditing skills apply?
Largely yes, including risk assessment and evidence gathering. The criteria differ.
