The internal auditor and the external auditor are two distinct roles involved in the auditing process of an organization. While both roles contribute to ensuring financial accuracy and compliance, there are key differences between them:


Scope and Reporting Line:

Internal Auditor: The internal auditor is an employee of the organization and works within the company. They are responsible for evaluating internal controls, risk management processes, and financial operations. Internal auditors report to management or the audit committee within the organization.

External Auditor: The external auditor is an independent professional or an auditing firm hired by the organization to conduct an external audit. They provide an objective assessment of the organization’s financial statements and overall financial position. External auditors typically report their findings to shareholders or stakeholders outside of the organization.


Internal Auditor: While internal auditors maintain objectivity and independence in their work, they are still part of the organization’s internal structure. Their primary focus is on assessing internal controls, risk management, and operational efficiency.

External Auditor: External auditors are completely independent of the organization. They are unbiased and provide an objective evaluation of the financial statements, ensuring they are prepared in accordance with applicable accounting standards and regulations.

Regulatory Requirements:

Internal Auditor: Internal auditors are not required by law but are often recommended or required by corporate governance guidelines. The scope and activities of internal auditors are determined by the organization’s needs, policies, and objectives.

External Auditor: External auditors are typically required by law or regulatory bodies, depending on the jurisdiction and the type of organization. They must comply with specific auditing standards and regulations set by the relevant authorities.

Focus of Work:

Internal Auditor: Internal auditors focus on assessing internal controls, risk management processes, operational efficiency, and compliance with policies and procedures. They aim to improve internal processes, identify operational weaknesses, and provide recommendations for improvement.

External Auditor: External auditors primarily focus on conducting an independent and comprehensive examination of the organization’s financial statements. Their main objective is to express an opinion on the fairness and accuracy of the financial statements, ensuring compliance with applicable accounting principles and regulations.

Nature of Relationship:

Internal Auditor: Internal auditors work closely with the organization’s management and staff. They may collaborate on improving internal processes, implementing controls, and addressing operational issues. Their role is more advisory and aimed at improving internal operations.

External Auditor: External auditors maintain an arms-length relationship with the organization and its management. They have limited interaction with the organization on a day-to-day basis and maintain objectivity and independence in their assessment of the financial statements.

In summary, the internal auditor focuses on assessing internal controls and operational efficiency within the organization and reports to management or the audit committee. On the other hand, the external auditor is an independent professional or firm responsible for conducting an objective examination of the financial statements and reporting their findings to external stakeholders
