Cost Audit and Cost Records under Section 148
Updated 11 October 2026 · Fact-checked
Cost records are books showing the cost of producing goods or services. A cost audit is an independent check of those records by a cost accountant in practice. Section 148 and the Cost Records and Audit Rules, 2014 say which companies must keep records, get an audit, appoint the auditor, and file reports in CRA forms.
Understand Cost Audit and Cost Records
A cost record is a set of books that tracks what it costs to make a product or provide a service: materials, labour, utilities, overheads and so on. A cost audit is a check that these records are kept properly and that the cost figures are fair. It is separate from the financial audit.
Section 148 of the Companies Act, 2013 has two levers. First, the Central Government can require specified classes of companies engaged in production of goods or providing services to maintain cost records. Second, it can direct an audit of those records for specified classes. The Companies (Cost Records and Audit) Rules, 2014 fill in the details: which industries, which turnover limits, what form, and what timelines.
The Rules split industries into two groups. Table A covers regulated sectors such as telecommunications, electricity, petroleum, fertilisers, sugar, tea and pharmaceuticals. Table B covers non-regulated sectors such as many industrial and manufacturing products. Rule 3 decides who must keep cost records. Rule 4 decides who must also get a cost audit. A company can keep cost records without needing an audit.
The cost auditor must be a cost accountant in practice (an individual or a firm holding a certificate of practice under the Cost and Works Accountants Act, 1959). The Board appoints the cost auditor. Where the company is required to have an audit committee under Section 177, the Board appoints on that committee's recommendation. A company that has no such committee does not need one for this purpose, and the Board appoints directly. The members ratify the remuneration. The company's statutory auditor cannot be appointed as cost auditor. The cost audit is in addition to the statutory audit, not a replacement.
The cost auditor reports to the Board. The company then files the report with the Central Government. Your answer in the exam should follow this flow: applicability, appointment, report, filing, penalty.
Key rules to remember
- Section 148(1): cost records
- Central Government specifies classes of companies engaged in production of goods or providing services that must maintain cost records
- Applies only to classes notified under the Rules, not to every company.
- Section 148(2): cost audit
- Central Government may direct audit of cost records for specified classes of companies
- Cost audit applies only to companies already covered for cost records and meeting the Rule 4 limits.
- Cost records threshold (Rule 3)
- Company in Table A or B with overall annual turnover ≥ ₹35 crore OR aggregate turnover of the individual products or services covered by the Tables ≥ ₹10 crore, in the immediately preceding financial year
- Either limit is enough. Remember the test is OR, not AND. Verify the limits against the current text of the Rules before the exam.
- Cost audit threshold, regulated sectors (Table A)
- Overall turnover ≥ ₹50 crore OR aggregate turnover of the individual products or services covered ≥ ₹25 crore
- Rule 4 applies only to a company already covered under Rule 3.
- Cost audit threshold, non-regulated sectors (Table B)
- Overall turnover ≥ ₹100 crore OR aggregate turnover of the individual products or services covered ≥ ₹35 crore
- Either limit is enough. Remember the test is OR, not AND. Rule 4 applies only to a company already covered under Rule 3.
- Exemptions
- Rule 3: a company that meets neither turnover test (₹35 crore overall or ₹10 crore covered products) has no cost records duty. Rule 4(3): the cost audit requirement does not apply to a company covered under Rule 3 whose export revenue in foreign exchange exceeds 75% of total revenue and which has no operations in a domestic non-SEZ area, to a company operating from a Special Economic Zone, or to a company generating electricity for captive consumption through a captive generation plant
- Rule 4(3) exempts from cost audit only, not from cost records. Do not assume any further exclusion, such as for small enterprises, unless you can point to the Rule that gives it.
- Cost record retention
- Cost records are kept in good order for at least 8 financial years immediately after the year to which they relate
- Records may be kept in physical or electronic form.
- Cost auditor appointment
- Board appoints within 180 days of the start of the financial year, on the recommendation of the audit committee where the company is required to have one under Section 177 (otherwise the Board appoints directly), after getting the auditor's written consent and eligibility certificate
- The auditor must be a cost accountant in practice. The statutory auditor cannot be appointed for cost audit.
- Form CRA-2
- Company informs the Central Government of the cost auditor's appointment within 30 days of the Board meeting date or within 180 days of the start of the financial year, whichever is earlier
- This is the appointment intimation form.
- Cost audit report timeline
- Cost auditor submits report (Form CRA-3) to the Board within 180 days of the close of the financial year; company files it with the Central Government in Form CRA-4 within 30 days of receiving it
- The company's filing must include full information and explanation on every reservation or qualification.
- Forms in brief
- CRA-1: cost records | CRA-2: appointment intimation | CRA-3: cost audit report | CRA-4: filing of the report with Central Government
- Learn these four. Examiners often ask which form applies to which step.
How to solve Cost Audit and Cost Records questions
Use this order for any question on cost records or cost audit. It matches how the answer is marked: provision, facts, conclusion.
- 1Identify what is asked: applicability, appointment, reporting, penalty, or comparison with financial audit.
- 2Check the sector. Is the product or service in Table A (regulated) or Table B (non-regulated)? If it is in neither, there is no cost records duty.
- 3Check the turnover tests in order. First Rule 3 for cost records: overall turnover of ₹35 crore or more, or covered-product turnover of ₹10 crore or more. Then Rule 4 for cost audit, using the Table A or Table B limit. In each rule either the overall or the covered-product test is enough.
- 4Check exemptions from cost audit under Rule 4(3): exports above 75% of revenue in foreign exchange (with no domestic non-SEZ operations), SEZ operation, and captive power generation. These do not remove the cost records duty.
- 5If an audit applies, work through appointment: Board appoints (on the audit committee's recommendation where the company must have an audit committee under Section 177), consent and eligibility certificate, 180-day limit, CRA-2 within 30 days, members ratify remuneration.
- 6Then reporting: cost auditor to Board in CRA-3 within 180 days of year end, company to Central Government in CRA-4 within 30 days of receipt.
- 7State the conclusion clearly in one sentence and mention the consequence of default (Section 148(8): the company and its officers in default are punishable as provided in Section 147(2) and (3)).
- 8Compute dates from the facts given. State your counting convention and show the arithmetic so you earn method marks even if a date is off by a day.
Quickest way: Applicability checklist: sector, turnover, exemption, timeline
When to use it: Use this when a case gives you a sector and turnover figures and asks whether cost records or a cost audit is required.
- Write the sector and whether it is Table A or Table B.
- Write the overall turnover and the covered-product turnover.
- Test cost records under Rule 3: ₹35 crore overall OR ₹10 crore covered products.
- Test the cost audit limit under Rule 4: Table A ₹50 crore or ₹25 crore; Table B ₹100 crore or ₹35 crore.
- Strike out the cost audit (not the cost records) if exports exceed 75% with no domestic non-SEZ operations, or the unit is in an SEZ, or it is captive power generation.
- Write the conclusion, then the forms and dates: CRA-2 within 30 days, report within 180 days of year end, CRA-4 within 30 days of receipt.
Common mistakes in Cost Audit and Cost Records
Saying every company must get a cost audit.
Students read Section 148 as a general rule, like the statutory audit under Section 139.
Fix: Remember that Section 148 works through notified classes. Always check the sector table and the turnover tests before concluding.
Mixing up the cost records limit with the cost audit limit.
The Rules use several turnover figures and students merge them.
Fix: Keep two rows: cost records at ₹35 crore overall or ₹10 crore covered products (Rule 3), and cost audit at Rule 4 limits that differ for Table A and Table B.
Treating the turnover tests as AND.
Students assume both overall and product turnover must be met.
Fix: Write 'overall OR individual product' in your notes, for both Rule 3 and Rule 4. Meeting either test makes the company liable, and Rule 4 applies only if the company is covered under Rule 3.
Applying only the ₹35 crore overall limit to decide on cost records.
Students remember one headline figure and forget the covered-product test.
Fix: Always test the ₹10 crore covered-product turnover as well. A company with overall turnover below ₹35 crore can still need cost records.
Appointing the statutory auditor as cost auditor.
Students think one firm doing both saves cost and is allowed.
Fix: The Act bars a statutory auditor appointed under Section 139 from conducting the cost audit. The cost auditor must be a cost accountant in practice.
Confusing who files what.
Both CRA-3 and CRA-4 relate to the report.
Fix: CRA-3 is the report format that the cost auditor gives to the Board. CRA-4 is the company's filing of the report with the Central Government. CRA-2 only intimates the appointment.
Treating the cost audit as a replacement for the financial audit.
Both examine books, so students see them as duplicates.
Fix: State that cost audit is in addition to the statutory audit. It checks cost records and cost efficiency; the financial audit gives an opinion on the financial statements.
Worked examples
Example 1
Medico Pharma Ltd manufactures drugs (a Table A sector). Its overall turnover in the previous year was ₹60 crore and the turnover of the covered product was ₹30 crore. It does not export and has no SEZ unit. Is it required to maintain cost records and get a cost audit?
Show the solution
- Provision: Section 148 with Rules 3 and 4 of the Cost Records and Audit Rules, 2014.
- Sector: pharmaceuticals fall in Table A (regulated sector).
- Cost records (Rule 3): the limits are overall turnover of ₹35 crore or covered-product turnover of ₹10 crore. Overall turnover of ₹60 crore is above ₹35 crore, and covered-product turnover of ₹30 crore is above ₹10 crore. Either test is enough, so the company must maintain cost records.
- Cost audit (Rule 4): for Table A the limits are overall turnover of ₹50 crore or covered-product turnover of ₹25 crore. Overall turnover of ₹60 crore exceeds ₹50 crore. The covered-product turnover of ₹30 crore also exceeds ₹25 crore. Either test is enough.
- Exemptions under Rule 4(3): no export above 75% of revenue and no SEZ operation, so none applies.
Answer: Medico Pharma Ltd must maintain cost records and get its cost records audited by a cost accountant in practice.
Example 2
Nirmal Chemicals Ltd (financial year starting 1 April 2027) is required to get a cost audit. Its Board appoints a cost auditor on 10 August 2027 on the audit committee's recommendation. The cost auditor's report for the year ended 31 March 2028 reaches the company on 20 September 2028. State the deadlines for CRA-2 and CRA-4 and the key compliance steps.
Show the solution
- Counting convention: for the 180-day limits, 1 April is counted as day 1 (for the appointment, the first day of the year; for the report, the day after the year end on 31 March 2028). For the 30-day limits, the day after the event is day 1.
- Before appointment, the company must get the cost auditor's written consent and certificate that the appointment meets eligibility and independence conditions. The auditor must be a cost accountant in practice, and cannot be the company's statutory auditor.
- Appointment timing: the Board must appoint within 180 days of the start of the year. April 30 + May 31 + June 30 + July 31 + August 31 = 153 days to 31 August, and 27 more days gives 180 days on 27 September 2027. So 10 August 2027 is within time.
- CRA-2: due within 30 days of the Board meeting or within 180 days of the start of the year, whichever is earlier. 30 days from 10 August 2027 is 9 September 2027. This is earlier than 27 September 2027, so CRA-2 is due by 9 September 2027.
- Remuneration: the members must ratify it by ordinary resolution.
- Report: the cost auditor must submit the report in the CRA-3 format to the Board within 180 days of the year end. Counting 1 April 2028 as day 1, the same arithmetic gives 27 September 2028, so receipt on 20 September 2028 is in time.
- CRA-4: the company must file the report with the Central Government within 30 days of receiving it. 30 days from 20 September 2028 is 20 October 2028. It must include full information and explanation on every reservation or qualification.
Answer: CRA-2 is due by 9 September 2027. CRA-4 is due by 20 October 2028. The auditor must be a cost accountant in practice other than the statutory auditor, and the members must ratify the remuneration.
Exam tips
- Open every applicability answer with the sector table, then the turnover test. This shows the examiner your method straight away.
- Memorise the four forms in one line: CRA-1 records, CRA-2 appointment, CRA-3 report, CRA-4 filing. Questions often test only this.
- For a difference between cost audit and financial audit, give 5 to 6 points: purpose, auditor, appointment, report recipient, focus and legal basis. Present them as bullet pairs.
- Compute dates in case-based answers and show the arithmetic. Always check whether 'whichever is earlier' changes the due date.
- Since the paper is descriptive, end with a one-line conclusion and the default consequence (Section 148(8): the company and its officers in default are punishable as provided in Section 147(2) and (3)).

Cost Audit and Cost Records: frequently asked questions
Who must get a cost audit under Section 148?
Only companies in the classes notified under the Cost Records and Audit Rules, 2014. These are companies in Table A or Table B sectors that meet the turnover limits and are not exempt. Always check the sector, the turnover and the exemptions together.
Who can be appointed as cost auditor?
A cost accountant in practice, either an individual or a firm. The Board appoints the cost auditor, on the audit committee's recommendation where the company must have an audit committee under Section 177.
