Internal Audit Differs From External Audit In Which Way?

Oct 29, 2023

Internal audit and external audit are two distinct processes that serve different purposes within an organization. While they share some similarities, they also differ in several key ways. 


Here, we'll explore these differences in detail.

Objective

  • Internal Audit: Internal audit is conducted by an organization's own employees, known as internal auditors. Their primary objective is to evaluate and improve the effectiveness of an organization's risk management, control, and governance processes. Internal auditors focus on helping the organization achieve its objectives by providing recommendations for improvement.
  • External Audit: External audit, on the other hand, is performed by independent, third-party audit firms. The primary objective of an external audit is to provide an opinion on the accuracy and fairness of an organization's financial statements. It ensures compliance with accounting standards and regulations.

Independence

  • Internal Audit: Internal auditors are employees of the organization. While they aim for objectivity, their independence can be influenced by their job security, organizational culture, and reporting structure.
  • External Audit: External auditors are independent of the organization. They have no vested interest in the company's operations or financial outcomes, which enhances their objectivity.

Reporting Line

  • Internal Audit: Internal auditors typically report to the organization's management or board of directors. Their reports are meant for internal use, focusing on improving internal controls and processes.
  • External Audit: External auditors report to shareholders or regulatory authorities. Their findings and opinions are shared in the form of an auditor's report attached to the company's financial statements.

Scope

  • Internal Audit: Internal audits can encompass a wide range of areas within the organization, including financial, operational, compliance, and strategic aspects. The scope is determined based on the organization's specific needs and objectives.
  • External Audit: External audits are primarily concerned with financial statement audits. They focus on verifying the accuracy of financial data, ensuring compliance with accounting principles, and providing assurance to external stakeholders.

Regulation

  • Internal Audit: While there are professional standards and guidelines for internal auditors (e.g., the Institute of Internal Auditors' International Professional Practices Framework), there is no universal regulation governing internal audits. These standards are more flexible and tailored to the organization's needs.
  • External Audit: External audits are subject to stringent regulations and standards, such as the Generally Accepted Auditing Standards (GAAS) in the United States. These regulations ensure a consistent and uniform approach to external audits.

Frequency

  • Internal Audit: Internal audits are typically conducted periodically throughout the year and can be continuous or scheduled at the discretion of the organization.
  • External Audit: External audits are typically annual events and are often a legal requirement for publicly traded companies.

In conclusion, internal audit and external audit differ in their objectives, independence, reporting lines, scope, regulation, and frequency. While internal audit is geared towards improving an organization's internal processes and controls, external audit focuses on providing assurance to external stakeholders about the accuracy and fairness of financial statements. Both types of audits play crucial roles in maintaining transparency, accountability, and good governance within organizations.
