Cost Audit Under Companies Act 2013: Who Needs It and How to Prepare

@cma_meera · 12 Feb 2026 · 2 min read
Cost audit is one of the most misunderstood compliance requirements under the Companies Act 2013. Many companies that need it do not know they need it. And many that do it treat it as a checkbox exercise. Both approaches are wrong.

WHO NEEDS COST AUDIT?
Companies engaged in production of goods or provision of services specified in the Companies (Cost Records and Audit) Rules, 2014 — provided they meet the threshold:
- Overall turnover from all products/services: Rs 100 crore or more in the preceding financial year, OR
- Overall turnover of individual product/service requiring cost records: Rs 35 crore or more

The specified industries include: pharmaceuticals, sugar, fertilisers, petroleum products, electricity, rubber products, paper, cement, textiles, glass, automobiles, engineering goods, and many more.

WHAT DOES COST AUDIT COVER?
Unlike statutory audit (which verifies financial statements), cost audit examines:
- Whether cost records are maintained as per CAS (Cost Accounting Standards)
- Whether the cost statements fairly represent the cost of production
- Whether there is proper allocation and absorption of overheads
- Material cost, labour cost, and manufacturing overhead analysis
- Capacity utilisation and its impact on per-unit cost
- Variance analysis between budgeted and actual costs

THE COMMON GAPS I FIND
1. Companies maintaining cost records in Excel but not following CAS — the format matters. CAS-4 (Cost of Production), CAS-6 (Material Cost), CAS-7 (Employee Cost) each have specific requirements.
2. Overhead allocation using arbitrary percentages rather than activity-based methods.
3. No reconciliation between cost records and financial accounts — this reconciliation statement is a mandatory part of the cost audit report.
4. Treatment of abnormal costs — these must be segregated and excluded from per-unit cost calculation.

PRACTICAL BENEFIT OF PROPER COST RECORDS
Beyond compliance, proper cost records help you identify which products are truly profitable after full cost allocation. I have seen manufacturing clients discover that their "best-selling" product was actually loss-making when overheads were properly allocated. That insight alone justified the entire cost of the cost audit.

TIMELINE
Cost auditor appointment: Within 180 days from the start of the financial year
Cost audit report filing (CRA-4): Within 30 days from receipt of cost audit report
CRA-3 (cost audit report by auditor): Within 180 days from the end of the financial year

The Section 148A ruling is from a Tribunal, not binding on other benches. Don't rely on it blindly.

Meera, the point about overhead allocation is critical. We switched from percentage-based allocation to activity-based costing last year and discovered two product lines were actually running at a loss.
