What is Internal Audit?

An independent evaluation conducted within a company to assess and improve the effectiveness of risk management, internal controls, and governance processes.

How It Works

Internal audit is performed by the company's own audit team or outsourced professionals to evaluate operational efficiency, financial reporting accuracy, compliance with laws and policies, and risk management effectiveness. Unlike external audit (statutory, by independent auditors for shareholders), internal audit serves management's needs. In India, companies with turnover exceeding ₹200 crore or paid-up capital above ₹50 crore must have an internal audit function under Section 138 of the Companies Act 2013. Internal auditors report to the Audit Committee.

Real-World Example

An internal audit of the procurement department reveals: 12% of purchase orders bypass the approval workflow, 3 vendors have no signed contracts, and 2 employees have both PO creation and payment approval rights (segregation of duties violation).
