What is Cost Audit?

Cost Audit is an independent review of a company's cost records and cost accounting systems to ensure accuracy, compliance with cost accounting standards, and efficient cost management. This audit helps in identifying cost inefficiencies, detecting misreporting, and improving overall cost control.

Objectives of Cost Audit

• Ensure cost records are maintained in compliance with Cost Accounting Standards (CAS).
• Identify cost inefficiencies and areas where cost control measures can be applied.
• Provide insights for better cost management and pricing strategies.
• Prevent cost manipulation and misreporting by companies.
• Ensure compliance with statutory requirements under the Companies Act, 2013.

Cost Audit is mandatory for certain industries under Section 148 of the Companies Act, 2013. It is applicable to:

• Companies engaged in regulated sectors such as petroleum, electricity, drugs, fertilizers, and telecommunications if their turnover exceeds ₹50 crore.
• Companies in non-regulated sectors like automobiles, cement, electronics, and IT hardware if their turnover exceeds ₹100 crore.

Who Conducts a Cost Audit?

Only a Cost Accountant (CMA) registered with the Institute of Cost Accountants of India (ICMAI) is authorized to conduct a Cost Audit. The auditor reviews cost records, verifies cost efficiency, and ensures that companies comply with cost reporting standards.
