Form 3CD Clause 37 for AY 2026-27: Cost Audit Reporting & Reconciliation
Updated: Sep 28
Form 3CD Clause 37 for AY 2026-27 asks a focused but important tax-audit question: was any cost audit carried out for the assessee, and if yes, were there any qualifications, disqualifications or disagreements on matters, items, values or quantities identified by the cost auditor? For companies covered by cost-audit requirements under Section 148 of the Companies Act, 2013, Clause 37 is the bridge between the statutory cost-audit file and the income-tax audit report. It should therefore be completed only after reconciling the final cost-audit report, Board records and the tax-audit working papers.
Update — 28 September 2026: CBDT changed the specified ordinary AY 2026–27 tax-audit report deadline from 30 September to 21 October 2026 and the related audited return deadline from 31 October to 21 November 2026. The separate Form 3CEB timetable is unchanged. Official Income Tax Department announcement.
Form 3CD Clause 37 for AY 2026-27: What Exactly Must Be Reported?
The Income Tax Department’s current tax-audit guidance states that Clause 37 requires the tax auditor to state whether any cost audit was carried out. Where the answer is yes, the auditor must provide details of any disqualification or disagreement on a matter, item, value or quantity reported or identified by the cost auditor. The clause is therefore not a duplicate cost audit. Its purpose is to surface material issues already identified in that separate statutory process.
This matters because a company may have three different assurance streams running in parallel: statutory financial audit under the Companies Act, cost audit under Section 148 where applicable, and tax audit under Section 44AB. Clause 37 requires the tax auditor to connect those streams where the cost audit contains findings relevant to the tax-audit report.
Applicable Law: Section 148 of the Companies Act and Cost Audit
Section 148 of the Companies Act, 2013 authorises the Central Government to prescribe classes of companies that must maintain specified cost records and, for prescribed classes, have those records audited by a cost accountant. A cost audit under Section 148 is in addition to the statutory audit under Section 143. The cost auditor submits the report to the Board, and the company must furnish the prescribed report and explanations to the Central Government within the applicable statutory framework.
For FY 2025-26, companies should test cost-record and cost-audit applicability under the Companies (Cost Records and Audit) Rules, 2014 as amended, based on the company’s sector, products or services and the current threshold conditions. Clause 37 should not be used as a substitute for that applicability analysis. The tax-audit team should obtain the company’s documented conclusion on whether cost audit applied and, where it did, obtain the final cost-audit report.
Who Should Pay Special Attention to Clause 37?
Manufacturing and service companies falling within sectors covered by the Companies (Cost Records and Audit) Rules, 2014.
Companies that appointed a cost auditor and filed or are preparing CRA-related compliances for FY 2025-26.
Groups where the finance team, cost-accounting team and direct-tax team operate separately and may not automatically share audit findings.
Businesses with significant inventory, yield, consumption, production, capacity, overhead-allocation or product-costing issues that can create differences between cost records and financial/tax records.
Companies where the cost-audit report contains reservations, qualifications, observations or disagreements requiring management explanation.
What Counts as a Qualification or Disagreement for Clause 37?
Clause 37 is intentionally broad. The Income Tax Department’s guidance refers to disagreement or disqualification relating to any matter, item, value or quantity. In practice, the tax auditor should read the cost-audit report and supporting management responses rather than relying only on a yes/no certificate from the finance team.
Examples that may require attention include differences in production quantities, abnormal material consumption, inventory or scrap quantities, cost allocation bases, capacity utilisation, valuation of inputs or outputs, classification of costs, related-party cost records, reconciliation between cost records and financial accounts, or a reservation affecting a material cost component. Whether every observation belongs in Clause 37 depends on the wording and significance of the final cost-audit report; the tax auditor should report what the clause requires without converting the tax-audit report into a reproduction of the entire cost audit.
Clause 37 Reconciliation: A Practical 8-Step Workflow
Step 1 — Confirm applicability: document whether the company was subject to cost records and cost audit for FY 2025-26 under the current Companies Act framework.
Step 2 — Obtain the final cost-audit report: use the signed report and final annexures, not a draft circulated before management responses.
Step 3 — Read all qualifications and observations: identify every reservation, disagreement or exception concerning matter, item, value or quantity.
Step 4 — Map each issue to the financial statements: determine whether the point affects inventory, consumption, revenue, expenses, fixed assets, related parties, provisions or other tax-audit disclosures.
Step 5 — Map the issue to Form 3CD: cross-check whether the same matter affects another clause such as closing stock, quantitative details, related-party payments, statutory dues, GST expenditure or turnover ratios.
Step 6 — Obtain management explanations and evidence: preserve reconciliation statements, Board explanations, revised workings and supporting ledgers.
Step 7 — Draft Clause 37 reporting precisely: describe the relevant cost-audit disagreement without overstating the cost auditor’s conclusion or management’s response.
Step 8 — Final consistency check: ensure Clause 37, financial statements, tax computation and other Form 3CD clauses do not contradict each other.
Worked Example: Cost-Audit Quantity Difference
Assume a manufacturing company is subject to cost audit for FY 2025-26. The cost auditor identifies a material difference between the production quantity in the cost records and the quantity reflected in the company’s production register. Management explains that the difference arose from rework and process loss entries posted late in the ERP. The final cost-audit report records the disagreement and management explanation.
For Clause 37, the tax auditor should not simply write ‘cost audit conducted — no issue’ because management ultimately reconciled the ERP. The final cost-audit report itself contains a disagreement on quantity, so the tax auditor should evaluate the required disclosure. The same issue should also be cross-checked against Form 3CD quantitative reporting, closing stock, scrap and yield information where relevant. The audit file should preserve the reconciliation that explains why the difference does or does not affect taxable income.
Clause 37 vs Clause 38 and Clause 39
Clause 37 deals with cost audit. Clause 38 separately asks whether an audit was conducted under the Central Excise Act, 1944 and, if so, the details of relevant disagreements. Clause 39 deals with an audit under Section 72A of the Finance Act, 1994 in relation to valuation of taxable services. These are separate questions. A company should not answer Clause 37 by referring generically to ‘other statutory audits’ without identifying the specific audit actually conducted.
Common Mistakes in Form 3CD Clause 37
Treating Clause 37 as the same thing as Section 37(1) business-expenditure reporting. Clause 37 of Form 3CD concerns cost audit; Section 37 of the Income-tax Act is a different provision.
Answering ‘No’ merely because CRA-4 filing was pending, even though a cost audit had actually been carried out.
Using a draft cost-audit report instead of the signed final report.
Ignoring a cost-audit qualification because management believes the issue is immaterial for income tax. The tax auditor must first test whether Clause 37 itself requires disclosure.
Failing to reconcile cost-audit observations with Clause 35 quantitative details, inventory valuation, turnover or other related tax-audit disclosures.
Copying the entire cost-audit report into Form 3CD rather than reporting the relevant disagreement or disqualification in a concise and accurate manner.
AY 2026-27 Filing Context
For FY 2025-26 / AY 2026-27, the tax audit continues under the Income-tax Act, 1961 through Form 3CA or Form 3CB together with Form 3CD. The ordinary tax-audit report deadline is 21 October 2026, subject to any valid extension and the separate timeline applicable to specified transfer-pricing cases. Companies that also have a cost audit should build the Clause 37 reconciliation into the audit close rather than waiting until the final tax-audit upload.

FAQs on Form 3CD Clause 37 AY 2026-27
Is Clause 37 applicable to every tax-audit assessee?
The clause appears in Form 3CD for all tax audits, but a substantive disclosure arises only where a cost audit was carried out. Many non-company taxpayers and companies outside the prescribed cost-audit framework will simply have no cost audit to report.
Does Clause 37 require the tax auditor to decide whether the company should have undergone cost audit?
The tax auditor should understand and document the company’s cost-audit applicability, especially where the business falls within industries covered by the Cost Records and Audit Rules. However, Clause 37 itself asks whether a cost audit was carried out and then requires details of relevant disagreements or disqualifications.
If the cost auditor gave no qualification, is detailed reporting still needed?
Where a cost audit was conducted but no reportable disagreement or disqualification exists, the tax auditor should complete the clause consistently with the prescribed form and the final cost-audit report. The working papers should still contain evidence that the report was reviewed.
Can a cost-audit issue affect other Form 3CD clauses?
Yes. A cost-audit observation can point to issues in stock quantities, material consumption, valuation, related-party costs, turnover or other financial data. Clause 37 should therefore be read together with the relevant clause-level reconciliations rather than in isolation.

Practical Takeaway
Form 3CD Clause 37 is short, but it is not a box-ticking field. If a cost audit was conducted, the tax-audit team should review the final cost-audit report, identify any disagreement or disqualification, reconcile it with the financial and tax records, and ensure the same issue is handled consistently across Form 3CD. For companies with cost audit exposure, the best control is a single issue register shared by the finance, cost-accounting and tax-audit teams before the 21 October 2026 tax-audit deadline.
