Cost Audit Under Section 148: Rules, CRA Forms & Fees (53 chars)

AEO Layer

Featured snippet (60 words): A cost audit is the examination of a company's cost records — what each product or service actually costs to make — by an independent cost accountant, mandated by Section 148 of the Companies Act 2013. It applies to companies in prescribed industries (pharma, cement, steel, telecom, electricity and others) above turnover thresholds of ₹50 crore or ₹100 crore. The cost auditor reports in Form CRA-3, which the company files with the Central Government in Form CRA-4.

PAA targets with answers: 1. *What is cost audit under Section 148?* It is the audit of cost records maintained under the Companies (Cost Records and Audit) Rules, 2014, conducted by a cost accountant in practice. Unlike a statutory audit, which checks whether financial statements give a true and fair view, a cost audit checks whether the company's records capture the true cost of each product or service — materials, labour, utilities, overheads — and whether those records follow the prescribed format. 2. *Which companies need cost audit in India?* Companies in prescribed regulated sectors (telecom, electricity, petroleum, drugs and pharmaceuticals, fertilizers, sugar) with overall turnover above ₹50 crore and individual product or service turnover above ₹25 crore; and companies in prescribed non-regulated sectors (cement, steel, chemicals, textiles, paper, glass, metals, construction and others) with overall turnover above ₹100 crore and individual product or service turnover above ₹35 crore. 3. *What is the difference between cost records and cost audit?* Cost records are the detailed books the company must maintain in Form CRA-1 showing how costs build up per product or service. A cost audit is the independent examination of those records by a cost auditor. Every company above the Rule 3 thresholds must maintain cost records; only companies above the Rule 4 audit thresholds need the audit itself. 4. *What is CRA-4 and when is it filed?* Form CRA-4 is the filing through which the company submits the cost audit report (CRA-3) to the Central Government, with full information and explanation on every reservation or qualification in the report. It must be furnished within 30 days of receiving the cost audit report. 5. *Who can conduct a cost audit?* Only a cost accountant in practice — a member of the Institute of Cost Accountants of India holding a certificate of practice — or a firm or LLP of cost accountants. The statutory auditor of the company cannot be appointed as its cost auditor.

Voice-search Q&As:

• *"Is cost audit mandatory for all companies?"* No. It applies only to companies engaged in the production of goods or provision of services in the prescribed industries, above the turnover thresholds in the Cost Records and Audit Rules. A software services company with ₹500 crore turnover, for example, is not covered; a pharma manufacturer with ₹60 crore turnover is.
• *"When should a cost auditor be appointed?"* Within 180 days of the commencement of the financial year. The appointment is made by the board, on the recommendation of the audit committee where one exists, and the shareholders ratify the auditor's remuneration. The company then files Form CRA-2 with the Central Government within 30 days of the board meeting or 180 days of the year's start, whichever is earlier.
• *"What happens if we don't maintain cost records?"* Under Section 148(8), the company and every officer in default face a fine of ₹25,000 to ₹5 lakh. The cost auditor in default faces the same fine range, plus imprisonment up to one year in serious cases.

Entity definition block: A cost audit (Companies Act 2013, Section 148; Companies (Cost Records and Audit) Rules, 2014) is the independent examination of a company's cost records — maintained in Form CRA-1 — by a cost accountant appointed under Rule 6. The cost auditor reports in Form CRA-3 within 180 days of the financial year's close, and the company files that report with the Central Government in Form CRA-4 within 30 days of receipt.

Quotable stats (sourced in register): 1. Cost records must be maintained by prescribed-industry companies with turnover above ₹50 crore (regulated sectors) or ₹100 crore (non-regulated sectors), with individual product or service turnover of ₹25 crore and ₹35 crore respectively (Rule 3). 2. The cost auditor must be appointed within 180 days of the financial year's commencement; Form CRA-2 is due within 30 days of the board meeting or 180 days of the year's start, whichever is earlier (Rule 6). 3. The cost audit report (CRA-3) must be submitted within 180 days of the close of the financial year (Rule 6(5)). 4. The company must file CRA-4 with the Central Government within 30 days of receiving the cost audit report (Rule 6(6)). 5. Penalties under Section 148(8): company and officers in default face fines of ₹25,000 to ₹5 lakh; a defaulting cost auditor faces the same fine plus possible imprisonment up to one year.

Overview

Most companies know what an audit of their financial statements looks like. Far fewer have heard of the audit that looks at what their products actually cost to make. That is the cost audit — and if your company manufactures drugs, cement, steel, chemicals, textiles, paper, or operates in electricity, telecom, petroleum or fertilizers, it may not be optional for you.

Section 148 of the Companies Act 2013 gives the Central Government the power to order the audit of cost records for specified classes of companies. The Companies (Cost Records and Audit) Rules, 2014 then name the industries and set the turnover thresholds. The logic is straightforward: in sectors where pricing matters to the public — medicines, power, fertilizers — or where cost discipline decides competitiveness — steel, cement, chemicals — the government wants an independent professional verifying that the company actually knows, records and reports what each unit of output costs.

The cost audit is not a second statutory audit. It does not re-check the profit and loss account or opine on the financial statements. It works one level deeper: into material consumption, labour, utilities, overheads, and the allocation of those costs across products. A company can have perfectly audited financial statements and still fail a cost audit if its product-level cost workings are guesswork. For management, though, this is the audit that pays for itself — the same workings that satisfy the cost auditor are the workings that reveal which product lines are profitable and which are quietly losing money.

This page covers the full framework: who must maintain cost records, who must get them audited, the CRA-1 to CRA-4 chain, appointment and filing deadlines, penalties, fees, and how ComplyKart manages the engagement for you.

Is a cost audit relevant to your company?

You need to look at this closely if your company:

• Manufactures, produces, processes or provides services in one of the prescribed industries — see the industry lists below — and
• Crosses the turnover thresholds in Rule 3: above ₹50 crore overall with ₹25 crore from individual prescribed products or services (regulated sectors), or above ₹100 crore overall with ₹35 crore from individual prescribed products or services (non-regulated sectors).

You are probably outside scope if:

• Your business is in services or industries not on the prescribed lists — IT services, trading, banking, hospitality, education, real estate and similar sectors are not covered.
• You are in a prescribed industry but below both thresholds — then neither cost records nor the audit apply to you.
• Your revenue from prescribed products is below the individual-product threshold even though overall turnover is high — the audit obligation is product-specific.

A trap worth flagging early: the turnover tests run on the preceding financial year's figures. A company that crossed ₹100 crore in FY 2024-25 falls into scope for FY 2025-26. Companies that grow fast in covered industries often discover this one year late — which is why the applicability check belongs in your year-end compliance review, not in a filing deadline scramble.

Cost records vs cost audit — know which obligation is yours

This is the distinction prospects most often get wrong, and getting it wrong is expensive in either direction. The Rules create two separate obligations with two separate thresholds.

Obligation 1: Maintain cost records (Rule 3). Every company engaged in the production of goods or provision of services in the prescribed industries, whose turnover from all products and services exceeds ₹35 crore in the preceding financial year, must maintain cost records in Form CRA-1. These are the detailed workings — per unit cost of production or operations, cost of sales, margin per product — maintained monthly, quarterly, half-yearly or annually. This is the wider net.

Obligation 2: Get the records audited (Rule 4). Among the companies maintaining cost records, those in regulated sectors with overall turnover above ₹50 crore (and ₹25 crore from individual prescribed products or services), and those in non-regulated sectors with overall turnover above ₹100 crore (and ₹35 crore from individual prescribed products or services), must additionally appoint a cost auditor and get the records audited. This is the narrower net.

In plain terms: records are the homework, the audit is the examiner. You can be required to do the homework without sitting the exam. But you cannot sit the exam without having done the homework — and the cost auditor will say so in the report if the records are inadequate.

The prescribed industries — regulated and non-regulated

Regulated sectors (Rule 3, Table A): 1. Telecommunication services 2. Generation, transmission, distribution and supply of electricity 3. Petroleum products 4. Drugs and pharmaceuticals 5. Fertilizers 6. Sugar industry

Non-regulated sectors (Rule 3, Table B) — the main ones: Cement; iron and steel; chemicals; tyres and tubes; textiles; paper; glass; aluminium; copper; zinc; coffee and tea; milk powder; insecticides; jute; edible oil; construction industry. The full Table B list in the Rules is longer — the entries above are the ones most companies encounter in practice.

Exemptions worth knowing: a company whose revenue from exports in foreign exchange exceeds 75% of total revenue from all products and services, or which operates from a Special Economic Zone, is outside the cost records requirement for the relevant period. These exemptions are product-specific and need care in application — they do not automatically exempt a multi-product company across all its lines. [NEEDS VERIFICATION: exact current text of the export/SEZ exemption conditions against the latest Rules at publish time.]

The CRA series — CRA-1 to CRA-4, what each form does

The four CRA forms are the entire compliance chain. Understand them in order and the whole framework falls into place.

CRA-1 — the cost records themselves. This is not a filing; it is the prescribed form in which cost records must be maintained. Rule 5 requires every covered company to maintain cost records for all its units and branches, for each financial year, in a manner that lets the company compute per-unit cost of production or operations, cost of sales and margin for each product and activity — on a monthly, quarterly, half-yearly or annual basis as suited to the business. The cost auditor examines these records; the government can call for them. Companies that keep only product-level estimates in spreadsheets, without the prescribed break-ups, are the ones that struggle at audit time.

CRA-2 — notice of appointment of the cost auditor. Filed electronically with the Central Government within 30 days of the board meeting at which the appointment is made, or within 180 days of the commencement of the financial year, whichever is earlier. It carries the prescribed fee and records who the cost auditor is. This is the form most commonly missed — companies appoint the auditor in July and forget the filing has its own 30-day clock running from the board meeting date.

CRA-3 — the cost audit report. The cost auditor's report itself, in the prescribed format, covering the cost records for the financial year. The auditor must submit it within 180 days from the close of the financial year. The report includes observations and suggestions, and the company must respond to every reservation or qualification.

CRA-4 — filing of the cost audit report with the Central Government. Within 30 days of receiving the cost audit report, the company furnishes the report to the Central Government in Form CRA-4, along with full information and explanation on every reservation or qualification the auditor made. This filing is in XBRL mode. A qualified report filed without explanations is an incomplete filing — and it invites scrutiny rather than closing the matter.

Advantages of a properly run cost audit

It tells you which products actually make money

Financial statements show aggregate profit. Cost records show per-product margins — which SKU, which plant, which service line is earning and which is being carried by the others. Companies that have never computed per-unit cost properly are routinely surprised by what the workings reveal.

It disciplines pricing decisions

In competitive tendering — government contracts, PSU procurement, large B2B bids — knowing your true floor cost is the difference between winning profitably and winning at a loss. Cost audit workings give management a defensible cost base for pricing.

It satisfies lenders and investors

Banks lending to manufacturing companies, and investors evaluating them, read cost audit reports for efficiency signals: material yields, capacity utilisation, overhead absorption. A clean cost audit record strengthens credit and valuation conversations.

It keeps the government relationship smooth

In regulated sectors — pharma pricing, power tariffs, fertilizer subsidies — cost data feeds directly into pricing and policy decisions. Companies with audit-ready records answer regulator queries in days; companies without them answer in months, under pressure.

It catches leakage early

Material consumption variances, abnormal wastage, utility overconsumption — the cost auditor's observations routinely surface operational issues that internal reporting has normalised. Several of these observations, addressed in time, pay for the audit many times over.

It protects the board from penalties

Section 148(8) puts personal consequences on officers in default. A managed cost audit calendar — appointment, CRA-2, report, CRA-4 — is the board's evidence that the obligation was taken seriously.

It feeds every other compliance

The cost workings reconcile with the financial statements that feed the statutory audit, the tax audit and GST filings. Consistent numbers across all four reduce scrutiny risk everywhere.

Documents and records the cost auditor will ask for

Corporate and appointment records:

• Board resolution appointing the cost auditor, audit committee recommendation where applicable, shareholder resolution ratifying remuneration
• Form CRA-2 filing acknowledgement
• Prior year's cost audit report and CRA-4 filing

Cost and production records (CRA-1 workings):

• Material consumption records — quantities, rates, variances per product
• Labour records — direct and indirect, attendance and cost allocation
• Utilities consumed — power, fuel, water, with allocation workings
• Overheads — factory, administration, selling and distribution, with allocation bases
• Capacity utilisation, production quantities, wastage and rejections
• Work-in-progress and finished goods valuations

Reconciliation records:

• Reconciliation of cost records with financial books — the auditor checks that the two tie
• Related-party transactions affecting cost
• Royalty, technical know-how and R&D allocations

The cost audit process — step by step

Step 1: Applicability check

Review the preceding year's turnover against the Rule 3 and Rule 4 thresholds, product by product. This should happen in April, at the start of the financial year — not in December when the appointment deadline has already passed.

Step 2: Board appointment of the cost auditor

The board appoints a cost accountant in practice (or a firm or LLP of cost accountants) within 180 days of the financial year's commencement. Where the company has an audit committee, the appointment and remuneration are recommended by the committee. The shareholders ratify the remuneration.

Step 3: File Form CRA-2

Within 30 days of the board meeting, or 180 days of the year's start, whichever is earlier — file the notice of appointment electronically with the Central Government.

Step 4: Maintain cost records through the year

The company maintains CRA-1 records for all units and branches through the financial year. This is not a year-end exercise; records built retrospectively in March are visible as such to an experienced auditor.

Step 5: Cost audit fieldwork

After the year closes, the cost auditor examines the records — typically 4 to 8 weeks for a mid-size single-plant company, longer for multi-plant operations. The auditor raises queries, tests allocations, and verifies reconciliations with the financial books.

Step 6: Cost audit report (CRA-3)

The auditor submits the report within 180 days of the financial year's close. The report carries observations, suggestions, reservations and qualifications where applicable.

Step 7: Company response and CRA-4 filing

The company prepares full information and explanations on every reservation or qualification, and furnishes the report to the Central Government in Form CRA-4 within 30 days of receipt.

How long does it take?

| Stage | Timeline | |---|---| | Applicability check and auditor appointment | April–September (within 180 days of 1 April) | | CRA-2 filing | Within 30 days of the board meeting | | Cost records maintenance | Through the financial year | | Audit fieldwork | 4–8 weeks after year-end (longer for multi-plant) | | CRA-3 report | Within 180 days of 31 March (by ~27 September) | | CRA-4 filing | Within 30 days of receiving the report |

For a 31 March year-end, the practical rhythm is: appoint by September, maintain records all year, audit fieldwork in April–June, report by September, CRA-4 by October.

Fees

Cost auditor fees are not fixed by statute — they depend on the number of plants, product lines, and the state of the cost records when the auditor arrives. As a practice indication, single-plant mid-size engagements typically run from the low lakhs, rising with multi-plant and multi-product complexity. [NEEDS VERIFICATION: fee bands rest on practice indication, not a published schedule — confirm at engagement.] ComplyKart's service fee covers the applicability analysis, appointment documentation, CRA-2 and CRA-4 filings, and audit coordination; the cost auditor's professional fee is separate and ratified by your shareholders as the law requires.

How ComplyKart helps

• Applicability analysis. Product-by-product turnover review against the Rule 3 and Rule 4 thresholds, with the export and SEZ exemptions tested before we conclude anything.
• Auditor appointment handled end-to-end. Board resolution drafting, audit committee recommendation where needed, shareholder ratification of remuneration, and CRA-2 filing inside the 30-day window.
• CRA-1 readiness. Gap analysis of your existing cost workings against the prescribed format — materials, labour, utilities, overheads, allocation bases — so the auditor arrives to records, not reconstruction.
• Audit coordination. Query management during fieldwork, reconciliation support between cost records and financial books, and drafting of the company's explanations on reservations and qualifications.
• CRA-4 filing. Preparation and XBRL filing within 30 days of the report, with the explanations that make a qualified report a closed matter rather than an open question.
• What we do not do. We do not sign cost audit reports — only a cost accountant in practice can. We do not invent cost workings or backdate records. The auditor's independence is the product; we manage the process around it, never the findings.

What happens after the cost audit

First 30 days: CRA-4 filed with the Central Government. Management reviews the auditor's observations — material variances, allocation suggestions, control points — and assigns owners for each.

First 6 months: Observation remediation: allocation bases corrected, wastage investigated, record-keeping gaps closed. The next year's CRA-1 maintenance starts on the improved template.

Year on year: Companies that treat the cost audit as a management tool rather than a filing obligation see the real return — per-product margins, pricing discipline, and tender competitiveness all improve on the back of the same workings.

Recurring compliance

• Annual: Applicability re-check each April, auditor appointment within 180 days, CRA-2 within 30 days of the board meeting, cost records maintained through the year, CRA-3 within 180 days of year-end, CRA-4 within 30 days of the report.
• Event-based: Change of cost auditor (fresh CRA-2), multi-plant additions (records extended to new units), new product lines (threshold re-testing).

Cost audit vs statutory audit vs tax audit — which is which

| | Cost audit | Statutory audit | Tax audit | |---|---|---|---| | Law | Sec 148, Companies Act | Sec 139–148, Companies Act | Sec 44AB, Income-tax Act | | Trigger | Prescribed industry + turnover thresholds | Every company | Turnover/gross receipts thresholds | | Examines | Product-level cost records | Financial statements | Books of account for tax computation | | Done by | Cost accountant | Chartered Accountant | Chartered Accountant | | Filed with | Central Government (CRA-4) | Shareholders / ROC via AOC-4 | Income-tax Department (Form 3CA/3CB + 3CD) |

A manufacturing company above the thresholds needs all three. They are not substitutes — each examines a different layer, and the numbers must reconcile across all three.

Common mistakes companies make

1. Missing the CRA-2 30-day window. The clock runs from the board meeting date, not from when someone remembers to file. A July appointment with an August filing is already late. 2. Treating cost records as a year-end exercise. CRA-1 records reconstructed in March from memory and estimates do not survive audit scrutiny — and the auditor is obliged to say so. 3. Assuming the statutory auditor covers this. The statutory auditor is expressly barred from being the cost auditor, and the statutory audit does not examine product-level cost workings. 4. Ignoring the individual-product threshold. Overall turnover above ₹100 crore does not trigger the audit if no single prescribed product or service crosses ₹35 crore. Test product by product. 5. Filing CRA-4 without explanations. A qualified report filed bare invites follow-up. The explanations are the filing's most important component. 6. Forgetting multi-plant coverage. Rule 5 requires records for all units and branches. A new plant added mid-year needs records from day one.

Penalties

Section 148(8) is blunt. If default is made in complying with the section:

• The company and every officer in default: fine of ₹25,000 to ₹5 lakh.
• The cost auditor in default: fine of ₹25,000 to ₹5 lakh, and in serious cases imprisonment up to one year, or both.

Beyond the statute, the practical penalties bite harder: MCA flagging on the company's public record, qualification in due-diligence searches, and in regulated sectors, awkward conversations with the pricing or tariff authority.

FAQs

1. What is a cost audit? An independent examination of a company's cost records — what each product or service costs to make — by a cost accountant, mandated by Section 148 of the Companies Act 2013 for companies in prescribed industries above turnover thresholds.

2. Which companies must maintain cost records? Companies in the prescribed regulated and non-regulated industries whose turnover from all products and services exceeds ₹35 crore in the preceding financial year (Rule 3). Records are maintained in Form CRA-1.

3. Which companies must get a cost audit done? Regulated-sector companies with overall turnover above ₹50 crore and individual product or service turnover above ₹25 crore; non-regulated-sector companies with overall turnover above ₹100 crore and individual product or service turnover above ₹35 crore (Rule 4).

4. What are the regulated sectors for cost audit? Telecommunication services; generation, transmission, distribution and supply of electricity; petroleum products; drugs and pharmaceuticals; fertilizers; and the sugar industry.

5. What are the non-regulated sectors? Cement, iron and steel, chemicals, tyres and tubes, textiles, paper, glass, aluminium, copper, zinc, coffee and tea, milk powder, insecticides, jute, edible oil and construction, among others listed in Table B of the Rules.

6. What is Form CRA-1? The prescribed form in which cost records must be maintained — per-unit cost of production or operations, cost of sales and margin per product, maintained monthly, quarterly, half-yearly or annually.

7. What is Form CRA-2? The electronic notice of appointment of the cost auditor, filed with the Central Government within 30 days of the board meeting or 180 days of the financial year's commencement, whichever is earlier.

8. What is Form CRA-3? The cost audit report itself, submitted by the cost auditor within 180 days of the close of the financial year.

9. What is Form CRA-4? The filing through which the company submits the cost audit report to the Central Government within 30 days of receipt, with explanations on every reservation or qualification — filed in XBRL mode.

10. Who can be appointed as cost auditor? A cost accountant in practice, or a firm or LLP of cost accountants. The company's statutory auditor cannot be appointed as its cost auditor.

11. When must the cost auditor be appointed? Within 180 days of the commencement of every financial year, by the board — on the audit committee's recommendation where one exists — with the remuneration ratified by shareholders.

12. Is cost audit the same as statutory audit? No. The statutory audit examines financial statements for a true-and-fair view; the cost audit examines product-level cost records. Different law (both under the Companies Act, but different sections), different professionals, different reports, different filings.

13. Are export-oriented companies exempt? Companies whose export revenue in foreign exchange exceeds 75% of total revenue, or which operate from a Special Economic Zone, have exemptions for the relevant products — but the conditions are product-specific and need careful application.

14. What if our cost records are inadequate? The cost auditor reports the inadequacy in CRA-3, and the company must explain it in CRA-4. Inadequate records are themselves a compliance failure — which is why the records should be built through the year, not reconstructed at year-end.

15. What are the penalties for non-compliance? Under Section 148(8): the company and every officer in default face fines of ₹25,000 to ₹5 lakh; a defaulting cost auditor faces the same fine and possible imprisonment up to one year.

16. How long does a cost audit take? Fieldwork typically runs 4 to 8 weeks for a single-plant mid-size company after year-end, longer for multi-plant operations. The report is due within 180 days of the financial year's close.

17. Does cost audit apply to service companies? Only if the services fall in the prescribed industries — telecommunication services and electricity supply are the main service-sector entries. General IT, consulting or trading services are not covered.

18. Can the same firm do our statutory and cost audit? No. The statute expressly provides that the statutory auditor cannot be appointed as the cost auditor of the company.

19. What does the cost auditor actually check? Material consumption, labour, utilities, overhead allocation, capacity utilisation, wastage, work-in-progress valuation, and the reconciliation of cost records with the financial books — product by product, unit by unit.

20. Why would management want a cost audit beyond compliance? Because the workings reveal per-product profitability, discipline pricing, surface operational leakage, and strengthen the company's hand with lenders, investors and government tender authorities. It is the rare compliance exercise that directly improves business decisions.
