How to File Form CRA-2 and CRA-4 for Cost Audit Compliance

Filing Form CRA-2 and Form CRA-4 is how a company covered under Section 148 of the Companies Act, 2013 completes its cost audit compliance cycle with the Ministry of Corporate Affairs. Form CRA-2 intimates the appointment of the cost auditor within 30 days of the Board meeting approving it, or 180 days of the financial year's commencement, whichever is earlier. Form CRA-4 later files the signed cost audit report, with an XBRL annexure, within 30 days of the Board receiving it from the cost auditor. This guide covers who this applies to under Rule 3 and Rule 4 of the Companies (Cost Records and Audit) Rules, 2014, the full appointment-to-filing process on the MCA V3 portal, current government fees, and the edge cases, such as a cost auditor resigning mid-year, that most process overviews skip.

Scope of this guide: the sections below cover cost record maintenance and cost audit applicability under Rule 3 and Rule 4, cost auditor appointment, Form CRA-2 intimation, Form CRA-3 report preparation, and Form CRA-4 filing under the Companies (Cost Records and Audit) Rules, 2014. It does not cover income tax audit under Section 44AB of the Income-tax Act, statutory financial audit under Section 143, or secretarial compliance audits, each governed by separate statutes and covered in our related guides linked through this article.

What Is Cost Audit Under Section 148?

Cost audit is an independent verification of a company's cost records, conducted by a Cost Accountant in practice appointed by the Board, confirming that the costs of materials, labour, and other resources used in producing goods or delivering services have been recorded, classified, and reported according to the applicable cost accounting standards. Section 148 of the Companies Act, 2013 gives the Central Government the power to require specified classes of companies to maintain such records and, separately, to require a subset of those companies to have the records audited.

The provision exists because cost data, unlike the financial statements every company must prepare, matters most to a narrower set of sectors: those where pricing is regulated, where the government has a stake in production efficiency, or where the scale of operations makes cost transparency a matter of public interest. Rather than requiring every company to track detailed cost data, Section 148 lets the government target specific product and service categories through the Companies (Cost Records and Audit) Rules, 2014, made under Section 148 read with Section 469.

Cost Audit vs Statutory Audit vs Internal Audit: Key Differences

These three terms are frequently confused because all three involve an "audit" of a company's records, yet each answers a different question, is governed by a different section, and applies to a different set of companies. Confusing them is one of the most common reasons companies either over-comply, by treating a cost audit obligation as satisfied through their regular financial audit, or under-comply, by assuming cost audit does not apply simply because a statutory audit has already been completed.

Statutory audit, under Section 143, verifies whether a company's financial statements present a true and fair view, and applies to every registered company regardless of sector or size. Internal audit, under Section 138, is a management-commissioned review of internal controls, risk management, and operational processes, mandatory only for companies crossing specified paid-up capital, turnover, borrowing, or deposit thresholds. Cost audit, under Section 148, is narrower still: it verifies cost records, applies only to companies in sectors listed under Rule 3, and only once the Rule 4 turnover thresholds are also crossed. A pharmaceutical manufacturer, for instance, may undergo all three in the same financial year: a statutory audit of its financial statements, an internal audit of its procurement controls, and a cost audit of the cost records for the specific drug formulations it manufactures, each producing a separate report to a separate audience. Our statutory audit vs tax audit guide and statutory audit requirements guide cover the other two audit types in more depth.

Legal Framework: The Companies (Cost Records and Audit) Rules, 2014

The current framework traces to a notification dated 30 June 2014, which superseded eight separate sector-specific cost accounting rules that had operated under the Companies Act, 1956. That single consolidated rule set, later amended to simplify the sector categories into two tables, now governs which companies maintain cost records in Form CRA-1, which of those companies must additionally undergo a cost audit resulting in a Form CRA-3 report, and how appointment and filing are intimated to the Central Government through Form CRA-2 and Form CRA-4 respectively.

Illustrative Timeline: CRA-2 and CRA-4 Deadlines for FY 2025-26

As of the FY 2025-26 filing cycle, working through one concrete financial year makes the two deadlines easier to track than reading the rule text alone. Take a company with a financial year running from 1 April 2025 to 31 March 2026, the standard cycle for most Indian companies. The Board must appoint the cost auditor and file Form CRA-2 by whichever comes first of 30 days from the appointing Board meeting or 180 days from 1 April 2025, which falls on 28 September 2025. The financial year closes on 31 March 2026, and the cost auditor then has until 180 days later, around 27 September 2026, to submit the signed Form CRA-3 report to the Board. Form CRA-4 is due 30 days after the Board actually receives that report, so if the report arrives on 27 September 2026, the CRA-4 filing deadline falls around 27 October 2026.

Two things stand out from this illustration. First, the CRA-2 deadline and the CRA-4 deadline sit roughly a year apart even in a fully compliant filing cycle, since the auditor's own 180-day reporting window only starts after the financial year closes. Second, a company that appoints its cost auditor promptly, soon after the financial year begins, does not gain any corresponding acceleration of the CRA-4 deadline, because that deadline runs from the report's actual delivery date rather than from the appointment date.

Who Must Maintain Cost Records and Undergo Cost Audit? Applicability Thresholds

Rule 3 and Rule 4 of the Companies (Cost Records and Audit) Rules, 2014 set out two distinct tests that a company must run every financial year: whether it must maintain cost records at all, and, separately, whether those records must be audited. Both tests use the immediately preceding financial year's turnover figures, so a company's obligations can change from one year to the next as its turnover moves.

A company in Table A whose overall turnover sits between ₹35 crore and ₹50 crore, for example, must maintain cost records but does not yet cross into cost audit territory. Once overall turnover reaches ₹50 crore and the specific qualifying product or service also reaches ₹25 crore in turnover, the same company becomes subject to a full cost audit under Rule 4, with the associated Form CRA-2 and Form CRA-4 filing obligations that follow an appointment.

Exemptions From Cost Audit

Rule 4(3) carves out two exemptions even where a company would otherwise cross the audit threshold: a company whose export revenue in foreign exchange exceeds 75% of total revenue is exempt, as is a company operating from a Special Economic Zone. Separately, companies classified as a micro or small enterprise under the turnover criteria in the Micro, Small and Medium Enterprises Development Act, 2006 fall outside the Table B cost records requirement entirely, meaning the cost audit question does not arise for them at all.

Table B: The Breadth of Non-Regulated Sectors Covered

Table B is considerably broader than Table A and catches many manufacturers who do not think of themselves as operating in a "regulated" industry at all. Beyond the headline categories of steel, cement, and construction, Table B also lists milk powder, insecticides, plastics and polymers, tyres and tubes, paper, textiles, glass, electrical and electronic machinery, and a defined list of medical devices such as cardiac stents and orthopaedic implants. A mid-sized manufacturer of plastic packaging or electrical components, for example, can find itself within Rule 3 scope purely by virtue of its product classification, well before it would think to check a compliance calendar built around "regulated industries."

Reviewing Applicability Every Financial Year

Because both thresholds run off the immediately preceding financial year's turnover, applicability is not a one-time determination made at incorporation or at first crossing a threshold. A company should reassess its Rule 3 and Rule 4 position as part of its year-end compliance calendar, alongside its statutory audit and annual filing preparation, since a company that fell below the threshold last year but crosses it this year has no grace period before the appointment and filing obligations begin.

Form CRA-2 vs Form CRA-4: Key Differences

Form CRA-2 and Form CRA-4 sit at opposite ends of the cost audit compliance cycle. CRA-2 is filed near the start of the financial year, before any audit work has taken place, simply to tell the Central Government who has been appointed as cost auditor. CRA-4 is filed near, or sometimes after, the close of the financial year, once the cost auditor has completed the audit and the Board has reviewed the resulting report.

Appointment of the Cost Auditor

The compliance cycle begins with the Board of Directors recommending and appointing the cost auditor, a step that must be completed and communicated through Form CRA-2 before any audit work formally begins. The appointment is a Board-level decision, not a shareholder-level one at the outset, though the remuneration the Board proposes must later be ratified by the members.

Board Recommendation and Remuneration Ratification

Under Rule 6(1), the Board appoints an individual, or a firm or LLP of Cost Accountants, as cost auditor within 180 days of the commencement of the financial year, on the recommendation of the audit committee where one exists. The remuneration payable to the cost auditor is recommended by the audit committee, considered and approved by the Board, and then ratified by the shareholders through an ordinary resolution, the mechanism set out under Rule 14, which mirrors, without duplicating, the shareholder involvement seen in statutory auditor appointments.

Eligibility and Restrictions on Cost Auditor Appointment

A cost auditor must be a Cost Accountant in practice, holding a valid certificate of practice, and must not be disqualified under the eligibility criteria applied to auditors generally. The proviso to Section 148(3) adds one specific restriction relevant to this appointment: a person who is already the company's statutory auditor, appointed under Section 139, cannot simultaneously serve as its cost auditor. This separation keeps the cost audit function independent of the financial statement audit rather than concentrating both roles in one professional relationship.

Step-by-Step Process to File Form CRA-2

Filing Form CRA-2 correctly depends on tracking two dates from the outset: the date of the Board meeting approving the appointment, and the date marking 180 days from the financial year's commencement. Whichever comes first sets the actual deadline.

Step 1: Confirm Applicability Before the Appointment Process Starts

Before convening the Board meeting, confirm using the immediately preceding financial year's turnover figures whether the company falls under Rule 3 for cost records, and separately whether Rule 4's audit threshold is also met. Skipping this check is a common reason companies either appoint a cost auditor unnecessarily or discover the requirement too late in the financial year to meet the 180-day window comfortably. Document this applicability determination in writing, ideally as part of the same Board note that later records the appointment, since it becomes the reference point if the classification is questioned in a later financial year.

Step 2: Convene the Board Meeting and Approve the Appointment

Place the cost auditor's appointment, along with the audit committee's recommendation on remuneration where applicable, on the Board meeting agenda. The resolution should record the auditor's name, membership details, the financial year the appointment covers, and the proposed remuneration, since these details feed directly into the Form CRA-2 fields. Where the company is appointing the same cost auditor for a subsequent financial year, the Board should still pass a fresh resolution rather than treating the earlier appointment as automatically continuing.

Step 3: Obtain the Cost Auditor's Written Consent

Collect a signed consent letter and eligibility certificate from the appointed cost auditor confirming acceptance of the appointment, absence of disqualification, and confirmation that the auditor is not the company's statutory auditor for the same financial year, satisfying the Section 148(3) proviso. Retain this consent alongside the Board resolution, since both documents are typically requested if the Registrar raises a query on the CRA-2 filing.

Step 4: Prepare and File Form CRA-2

Complete Form CRA-2 on the MCA V3 portal with the company's CIN, the cost auditor's membership number, the financial year covered, and the appointment date, attaching the certified Board resolution. File within 30 days of the Board meeting or 180 days of the financial year's start, whichever is earlier. Cross-check every data field against the Board resolution before submission, since a mismatch between the resolution date and the date entered on the form is a frequent cause of a Registrar query.

Step 5: Pay the Fee and Retain Proof of Filing

Complete payment of the applicable government fee through the portal's payment gateway and retain the Service Request Number, challan, and acknowledgment, since these documents evidence timely intimation if the appointment date is ever questioned. Store a copy in the company's statutory records alongside the minutes of the appointing Board meeting.

Step 6: Notify the Cost Auditor of the Completed Filing

Once CRA-2 is accepted, formally notify the cost auditor that the intimation has been filed, so the auditor can begin planning the audit timeline against the Rule 6(5) deadline for submitting the completed report to the Board. Sharing the acknowledgment with the auditor at this stage also gives them a documented starting point for their own engagement records.

MCA V3 Portal Walkthrough for Form CRA-2

As of the FY 2025-26 filing cycle, Form CRA-2 is filed exclusively through the MCA21 Version 3 (V3) portal's web-form interface, which replaced the downloadable PDF eForm process used on the earlier MCA21 V2 system. The web-form format means data is entered directly in the browser rather than filled offline and uploaded, and the portal validates fields such as CIN and auditor membership number in real time before submission.

1. Log in to the MCA V3 portal using the company's registered business user credentials linked to its CIN.
2. Navigate to the MCA services menu and select company e-filing, then locate Form CRA-2 under the cost audit-related forms category.
3. Enter the company's CIN to auto-populate the registered name, registered office address, and other master data for verification before proceeding.
4. Select the type of intimation, distinguishing a fresh appointment from a casual vacancy appointment, since the form captures slightly different supporting details for each.
5. Enter the cost auditor's details, including membership number, firm registration number if applicable, and the financial year the appointment covers.
6. Upload the Board resolution and the cost auditor's consent letter as attachments in the portal's accepted file formats.
7. Affix the Digital Signature Certificate of the authorised director, CFO, or Compliance Professional to the completed web-form.
8. Proceed to payment, where the portal calculates the fee automatically based on the company's recorded nominal share capital slab.
9. Download the acknowledgment and note the Service Request Number for future reference and for the cost auditor's records.

Two preparatory steps make this walkthrough go faster in practice. First, confirm the business user credentials used to log in have the correct authorisation level for cost audit-related forms before the Board meeting concludes, since a credential mismatch discovered on filing day can itself consume a working day of the 30-day window. Second, keep the Board resolution and the cost auditor's consent letter as separate, individually named attachments rather than a single combined scan, since the portal's attachment fields are typically configured for one document type per upload slot.

Government Fee and Additional Fee for Form CRA-2

The Cost Audit Report and the Path to CRA-4

Once the cost auditor is appointed and Form CRA-2 is filed, the compliance cycle shifts from an intimation obligation to a substantive audit obligation. The auditor examines the cost records maintained in Form CRA-1 against the applicable cost accounting standards, and the resulting report becomes the basis for Form CRA-4.

Rule 6(5): The 180-Day Reporting Window

The cost auditor must forward the signed cost audit report, in Form CRA-3, to the company's Board of Directors within 180 days from the closure of the financial year to which the report relates. For a financial year ending 31 March, this places the outer deadline for the auditor's submission to the Board around late September of the same calendar year, running in parallel with, but separate from, the statutory audit and annual filing timelines.

Cost Accounting Standards and the Content of the Cost Audit Report

The cost auditor's examination is not a freeform review; Rule 5 requires that cost records be maintained, and the audit conducted, with reference to the Cost Accounting Standards issued for the relevant industry, which set out the recognised basis for classifying, allocating, and reporting elements of cost such as material, employee, and overhead costs. Form CRA-3 itself follows a prescribed format that requires the auditor to report on whether the cost records have been maintained in the form and manner required, whether the company has complied with the applicable Cost Accounting Standards, and to record any observations, reservations, or qualifications distinctly, rather than folding them into a general narrative. This structured format is what allows the Board's explanatory note under Form CRA-4 to respond point by point to each qualification rather than issuing a single blanket comment.

Board's Report Disclosure and Audit Committee Role

Once the Board receives the cost audit report, its role is not limited to forwarding it to the Central Government. Where the company has an audit committee under Section 177, that committee typically reviews the cost audit report's findings, including any reservations or qualifications, alongside its review of the statutory audit, before the Board finalises its explanatory note. The Board's Report for the financial year, prepared under Section 134, must then disclose the fact that a cost audit was conducted and summarise any qualifications the cost auditor raised, giving shareholders visibility into the outcome even though the full CRA-3 report itself is filed separately with the Registrar.

Step-by-Step Process to File Form CRA-4

Filing Form CRA-4 depends on two things happening in sequence: the cost auditor delivering the signed report to the Board, and the Board completing its own review before the 30-day filing clock runs out.

Step 1: Receive and Log the Cost Audit Report

Record the exact date the Board receives the signed Form CRA-3 report from the cost auditor, since this date, not the financial year's closure, starts the 30-day countdown for filing Form CRA-4. Companies with a formal document management system typically log this date through the internal compliance office so that the deadline is tracked independently of when individual Board members personally review the report.

Step 2: Review Reservations and Qualifications

Circulate the report to the audit committee, where one exists, and prepare the Board's written explanation for every reservation, qualification, or adverse remark the cost auditor has recorded, since Form CRA-4 requires this explanatory note as a mandatory field, not an optional attachment. Draft this explanation in coordination with the cost auditor where practical, so the Board's response accurately reflects the auditor's underlying concern rather than a generic acknowledgment.

Step 3: Convert the Report Into an XBRL Instance Document

Map the finalised Form CRA-3 report, together with the Board's explanatory note, into the MCA-prescribed cost taxonomy using XBRL-compatible software, then run the instance document through the MCA validation tool to clear the mandatory tagging and calculation checks before it can be attached to the form. Reconcile every tagged figure back to the underlying CRA-3 report line by line, since a tagging mismatch discovered after CRA-4 has been submitted is considerably harder to correct than one caught during validation.

Step 4: File Form CRA-4 With Attachments

Submit the completed Form CRA-4 on the MCA V3 portal, attaching the validated XBRL instance document and the Board's explanatory note, within 30 days of the Board's receipt of the report, and affix the authorised signatory's Digital Signature Certificate. Where the cost auditor operates multiple product lines with separate reports, confirm that the XBRL instance document consolidates all product-line reports rather than treating each as a standalone filing, unless the applicable taxonomy version specifically calls for separate submissions.

Step 5: Pay the Fee and Update the Board's Report

Pay the applicable government fee, retain the acknowledgment, and ensure the fact of the CRA-4 filing, along with a summary of any qualifications, is reflected in the Board's Report for that financial year before it is placed at the Annual General Meeting. Keep the acknowledgment and the underlying CRA-3 report together in the statutory records, since both are typically requested together if a later inspection or inquiry examines the cost audit trail for that financial year.

MCA V3 Portal Walkthrough for Form CRA-4 and the XBRL Annexure

Form CRA-4 carries an extra preparatory step compared with Form CRA-2: the XBRL conversion must be completed and validated before the web-form submission can proceed, since the portal will not accept an unvalidated or incorrectly tagged instance document as an attachment.

1. Prepare the XBRL instance document offline using XBRL-compatible software mapped to the MCA's cost audit report taxonomy, tagging each line item of the Form CRA-3 report and the Board's explanatory note.
2. Validate the instance document using the MCA's XBRL validation tool, resolving any tagging errors or calculation mismatches the tool flags before attempting to upload it.
3. Log in to the MCA V3 portal and navigate to Form CRA-4 under the cost audit filing category.
4. Enter the company's CIN and confirm the auto-populated master data, including the cost auditor details already on record from the CRA-2 filing.
5. Enter the financial year the cost audit report relates to and the date the Board received the signed report.
6. Upload the validated XBRL instance document as the primary attachment, along with any additional annexures the form specifies.
7. Affix the Digital Signature Certificate of the authorised signatory and complete the declaration section confirming the attached document reflects the Board-reviewed report.
8. Proceed to payment of the applicable government fee and submit the form.
9. Download the acknowledgment and Service Request Number, and retain both alongside the cost auditor's original signed report for the company's records.

A technical detail worth flagging because general filing checklists rarely cover it: most Form CRA-4 rejections trace not to an error in the underlying Form CRA-3 report but to a mismatch between the XBRL instance document's declared taxonomy version and the version the MCA V3 portal's server-side validator currently enforces. Because the cost audit taxonomy is a narrower, more specialised schema than the mainstream financial-statement taxonomy, filing software vendors tend to update it less frequently, so an instance document that validates cleanly in a desktop tool last configured for an earlier filing cycle can still fail the portal's own check on upload. A second recurring cause surfaces when a company consolidates cost audit reports for more than one product line into a single instance document: each product line's figures must share a common reporting period context while remaining tagged as a distinct business segment, and a context reference copied across product lines without updating its segment tag is a frequent source of a calculation-check failure that only appears at the validation stage, not while the underlying CRA-3 report is being drafted.

Government Fee and Additional Fee for Form CRA-4

Form CRA-4 follows the same nominal-share-capital-based fee slab as Form CRA-2, ranging from ₹200 for companies with share capital below ₹1 lakh to ₹600 for companies with share capital of ₹1 crore or more, with the same additional fee multiplier structure applying where the 30-day filing window from receipt of the report is missed.

Consequences of Non-Filing Under Section 148(8)

Late filing is a fee problem before it becomes a penalty problem, but continued non-compliance escalates well beyond the additional fee multipliers described earlier. Section 148(8) of the Companies Act, 2013 imports the penalty structure that applies to statutory audit-related defaults under Section 147, applying it separately to the company and its officers, and to a defaulting cost auditor.

These penalties apply independently of the additional fee for late filing. A company that eventually files Form CRA-2 or Form CRA-4 after a long delay pays the additional fee to have the filing accepted, but that payment alone does not extinguish exposure under Section 148(8) if the delay reflects a genuine default in the underlying obligation rather than a short administrative lag.

In practice, most delayed filings are resolved through the additional-fee mechanism described earlier without escalating to prosecution, since Registrars generally treat a delayed-but-completed filing differently from a filing that never happens at all. Prosecution and the Section 148(8) penalty framework tend to come into play where the Registrar of Companies identifies a pattern of non-compliance during scrutiny, such as a company that meets the Rule 3 and Rule 4 thresholds but never appoints a cost auditor or files CRA-2 or CRA-4 at all for a given financial year, rather than a single late filing that is otherwise complete and accurate.

Common Mistakes When Filing CRA-2 and CRA-4

Most delays and rejections in cost audit filings trace back to a handful of avoidable errors, each rooted in treating the appointment and reporting timelines as more flexible than the Rules actually allow.

What links most of these errors is a shared assumption that the cost audit compliance calendar can be inferred from the more familiar statutory audit and annual filing calendar. It cannot: the appointment deadline, the reporting deadline, and the filing deadline for cost audit each run on their own trigger dates, set independently in the Rules rather than mirrored from Section 143 or Section 137. Building a separate tracking entry for Form CRA-2 and Form CRA-4, rather than folding them into a generic "audit compliance" checklist item, is the simplest way to avoid most of the mistakes above.

Edge Cases and Complex Filing Scenarios

The straightforward appointment-to-filing cycle described above covers most companies, but three recurring scenarios need separate handling.

Cost Auditor Resignation Mid-Year: Casual Vacancy and Fresh CRA-2

Where a cost auditor resigns, dies, or is removed partway through the financial year, Rule 6(3A) requires the Board to fill the resulting casual vacancy within 30 days of it arising. The company must then file a fresh Form CRA-2 within 30 days of that replacement appointment, treated as a distinct filing event from the original appointment, with its own 30-day clock rather than any leftover time from the earlier filing.

Companies With Multiple Product Lines Requiring Multiple Cost Auditors

A company producing goods or services across more than one Rule 3 category, for example both a regulated Table A product and a separate Table B product, may need the Board to appoint different cost auditors for different products, services, or plants, particularly where the scale or technical nature of each line warrants separate expertise. Each such appointment is a distinct event under Rule 6, and each is intimated through its own Form CRA-2 filing rather than a single combined intimation covering multiple auditors.

Sector Reclassification and Threshold Changes Affecting Applicability

Because Rule 3 and Rule 4 are periodically amended, and because a company's own product mix and turnover shift year to year, a company should not assume today's applicability position is permanent. A product line reclassified into a regulated sector, or a non-qualifying product whose turnover crosses the Rule 4 threshold after a strong sales year, brings the company within cost audit scope starting from the financial year following the one in which the threshold was actually crossed, based on audited figures rather than in-year projections.

When the Cost Audit Report Carries a Qualified Opinion

Where the cost auditor's Form CRA-3 report includes a reservation, qualification, or adverse remark rather than an unqualified opinion, the filing obligation does not change, but the content of the Board's explanatory note does. Form CRA-4 requires the Board to record its response to each qualification distinctly, rather than filing a single generic acknowledgment, and the Board's Report under Section 134 must summarise the qualification for shareholders in similarly specific terms. Where a qualification points to a genuine gap in the company's cost record maintenance, such as an allocation basis inconsistent with the applicable Cost Accounting Standard, addressing that gap before the following financial year's audit begins is generally more useful than treating the qualification as a one-off item to note and move past.

Post-Filing Compliance Obligations and Cross-References

Filing Form CRA-4 is not the final step in the compliance chain. The Board's Report for the financial year, prepared under Section 134, must disclose that a cost audit was conducted and summarise any qualifications the cost auditor raised, giving members visibility at the Annual General Meeting into findings that are otherwise filed only with the Registrar. Where the company has an audit committee under Section 177, that committee's oversight of the cost audit findings is typically referenced in the same section of the Board's Report that addresses the statutory auditor's observations, giving shareholders a single, consolidated view of both audits rather than two disconnected disclosures. The signed Form CRA-3 report, the Board resolution approving the explanatory note, and the CRA-4 acknowledgment together form the documentary trail that a company should be able to produce in full if the cost audit compliance for a given financial year is later examined.

Companies that also maintain a statutory auditor relationship should track the two filing calendars separately: our ADT-1 auditor appointment guide covers the parallel process for statutory auditor appointment, and our tax audit report filing guide addresses the separate Income-tax Act obligation that runs on its own timeline. Companies coordinating multiple ROC filings around the same financial year-end may also find it useful to review event-based filing requirements more broadly through our ROC annual filing coordination assistance.

Summary

Cost audit compliance under Section 148 of the Companies Act, 2013 runs on two connected but separately timed filings: Form CRA-2, intimating the cost auditor's appointment within 30 days of the Board meeting or 180 days of the financial year's start, whichever is earlier, and Form CRA-4, filing the completed cost audit report with an XBRL annexure within 30 days of the Board receiving it. Applicability itself depends on two distinct thresholds under Rule 3 and Rule 4, tested afresh every financial year against the immediately preceding year's turnover, and companies should track both the appointment clock and the reporting clock separately rather than assuming the two run on the same calendar. Getting the sequence right, from applicability check through Board appointment, CRA-2 filing, the cost auditor's 180-day reporting window, and the final CRA-4 submission, avoids both the escalating additional fee for delay and the Section 148(8) penalty exposure that follows genuine non-compliance.
