Cost Auditing Standards and Compliance Reporting

Updated 10 October 2026 · Fact-checked

Cost auditing standards are standards issued by the Institute of Cost Accountants of India, with Central Government approval, which a cost auditor must follow under Section 148(3). The cost auditor reports to the Board, and the company sends the report to the Central Government within thirty days of receiving it.

Understand Cost Auditing Standards and Compliance Reporting

A cost audit checks the cost records of a company, not its financial statements. The Central Government decides which classes of companies must keep cost records and which must get them audited. Section 148 is the legal base for this.

The cost auditor must follow cost auditing standards. Section 148(3) explains the term: standards issued by the Institute of Cost Accountants of India, constituted under the Cost and Works Accountants Act, 1959, with the approval of the Central Government. So the standards are not optional guidance. The second proviso to Section 148(3) makes compliance a duty of the cost auditor. ICMAI issues these as Cost Auditing and Assurance Standards (CAAS), for example CAAS 101 and CAAS 102. Learn what each number covers from your study material, and do not guess its title in the exam.

Reporting follows a clear chain. The cost auditor submits the report on the audit of cost records to the Board of Directors (proviso to Section 148(5)). The company then has thirty days from receiving a copy of the report to furnish it to the Central Government. It must attach full information and explanation on every reservation or qualification in it (Section 148(6)).

The Central Government may then ask for more information or explanation, and the company must give it within the time specified (Section 148(7)). If anyone defaults, penalties apply under Section 148(8). The company and its officers in default are punishable as provided in Section 147(1). The cost auditor in default is punishable as provided in Section 147(2) to (4).

Two more points matter. A cost audit is in addition to the audit under Section 143 (Section 148(4)). And a person appointed as the company's auditor under Section 139 cannot be appointed to conduct the cost audit (first proviso to Section 148(3)).

Key rules to remember

Cost auditing standards: Standards issued by ICMAI, with Central Government approval (Section 148(3), Explanation); The cost auditor must comply with them (second proviso to Section 148(3)).
Who appoints the cost auditor: Board appoints; remuneration determined by members in the prescribed manner (Section 148(3)); The Section 139 statutory auditor cannot be appointed as cost auditor.
Who receives the cost audit report first: Cost auditor → Board of Directors (proviso to Section 148(5)); The report goes to the Board, not directly to the Government.
Filing with Central Government: Company furnishes report within 30 days of receiving a copy, with full information and explanation on every reservation or qualification (Section 148(6)); The duty is on the company, and the clock runs from receipt of the copy.
Further information: Central Government may call for more; company furnishes within time specified (Section 148(7)); Arises after the Government considers the report and the company's explanation.
Penalty for default: Company and officers in default: Section 147(1). Cost auditor in default: Section 147(2) to (4). (Section 148(8)); Section 148(8) points to Section 147; the exact penalty amounts sit in Section 147, which is not reproduced here.
Relation to Section 143 audit: Cost audit is in addition to the Section 143 audit (Section 148(4)); One does not replace the other.

How to solve Cost Auditing Standards and Compliance Reporting questions

Use this method for any theory or case question on cost auditing standards, reporting or penalties.

1Identify what is asked: standards, appointment, reporting, or penalty. Each has its own sub-section of Section 148.
2Write the rule in plain words and cite the sub-section only if you are sure of it.
3For standards, state who issues them (ICMAI), that Central Government approval is needed, and that the cost auditor must comply.
4For reporting, trace the chain in order: cost auditor to Board, then company to Central Government within 30 days, then any further information called for.
5For defaults, name who is liable: the company and officers in default, and the cost auditor in default, with the Section 147 link.
6In case questions, test each fact against the rule: who was appointed, who got the report, how many days passed.
7Close with a one-line conclusion that answers the exact question.

Quickest way: Report chain check

When to use it: Use for MCQs and short case questions on who does what, and when.

Draw the chain: Auditor → Board → Company → Central Government.
Attach the number 30 days to the company's step, counted from receipt of the copy.
Attach 'every reservation or qualification' to the explanation the company must give.
Check the auditor: must be a cost accountant, and not the Section 139 auditor.
For penalty, remember that Section 148(8) refers to Section 147 and gives two limbs: company and officers, and cost auditor.

Common mistakes in Cost Auditing Standards and Compliance Reporting

Saying the cost auditor sends the report directly to the Central Government.
Students merge the auditor's step with the company's step.
Fix: The auditor submits to the Board. The company furnishes it to the Central Government within thirty days of receiving a copy.
Counting the 30 days from the end of the financial year.
Other filing deadlines are tied to year-end.
Fix: Section 148(6) counts from the date the company receives a copy of the cost audit report.
Thinking the statutory auditor can also do the cost audit.
Both are audits of the same company.
Fix: The first proviso to Section 148(3) bars a person appointed as auditor under Section 139 from conducting the cost audit.
Treating cost auditing standards as mere ICMAI guidance.
The word 'standard' sounds advisory.
Fix: The second proviso to Section 148(3) says the cost auditor shall comply with them, and they are issued with Central Government approval.
Quoting exact penalty amounts for Section 148 default.
Students try to sound precise.
Fix: Say that Section 148(8) applies Section 147: sub-section (1) to the company and officers in default, and sub-sections (2) to (4) to the cost auditor. Give amounts only if your material states them and you are sure.
Believing the cost audit replaces the Section 143 audit.
Both examine records, so students see duplication.
Fix: Section 148(4) says the cost audit is in addition to the Section 143 audit.

Worked examples

Example 1

Sunrise Textiles Ltd is covered by a Central Government order for cost audit. Its cost auditor completed the audit and handed the cost audit report to the Board on 10 July. The company received a copy on 12 July. State the latest date by which the company must furnish it to the Central Government, and what must accompany it.

Show the solution

The report goes first to the Board, as the proviso to Section 148(5) says. This step is done on 10 July.
Section 148(6) gives thirty days from the date the company receives a copy of the report.
The copy was received on 12 July. Days left in July after 12 July: 31 − 12 = 19. Remaining days: 30 − 19 = 11.
So the thirtieth day is 11 August.
The company must send full information and explanation on every reservation or qualification in the report.

Answer: The company must furnish the report to the Central Government by 11 August, together with full information and explanation on every reservation or qualification in it.

Example 2

Explain the legal position if Meera & Co, the statutory auditors of Kaveri Pumps Ltd appointed under Section 139, are also appointed as its cost auditors, and if the company fails to furnish the cost audit report to the Central Government.

Show the solution

On the appointment: the first proviso to Section 148(3) says no person appointed under Section 139 as auditor can be appointed to conduct the audit of cost records.
So the appointment of Meera & Co as cost auditor is not permitted. The Board must appoint a separate cost accountant.
The cost audit is in addition to the Section 143 audit (Section 148(4)), so it cannot be merged into the statutory audit.
On the failure to furnish the report: Section 148(6) places the duty on the company to furnish it within thirty days of receiving a copy.
Under Section 148(8)(a), the company and every officer in default are punishable as provided in Section 147(1). If the cost auditor is in default, Section 148(8)(b) applies Section 147(2) to (4) to the cost auditor.

Answer: Meera & Co cannot be appointed cost auditor because they are the Section 139 auditors. The company's failure to furnish the report within thirty days makes the company and officers in default liable under Section 147(1), as Section 148(8)(a) provides.

Exam tips

In MCQs, watch the time limit and the recipient. The options usually swap Board and Central Government, or change 30 days.
In written answers, use the order: standards, appointment, report to Board, filing with Government, further information, penalty. It earns step marks.
Cite Section 148 sub-sections only where you are sure. A correct rule without a number still earns marks.
Do not list penalty amounts unless you are certain. State who is liable and under which part of Section 147.
Link to Cost Audit Programme and Cost Audit Report as well. Questions often mix reporting with the report's content.
