Frequently asked questions about Internal Auditors


What is the difference between an Internal Auditor and an Accountant?

Internal Auditors and Accountants both work with financial data, but they serve distinct roles within a company. Accountants keep track of a company’s day-to-day financial transactions and help build systems to handle future budgeting needs. Internal Auditors review the accuracy of these transactions and make sure that existing and new procedures operate in the best interest of the company and its clients. Where Accountants are an active part of internal operations, Internal Auditors provide an external perspective on the impact of accounting behaviors. Accountants collaborate with Internal Auditors to provide them with access to relevant company records.


What are the daily duties of an Internal Auditor?

Internal Auditors start a project by creating checklists that describe the structures they will assess, allowing them to outline their expectations and compare them to actual occurrences within the company. They review financial statements, investment reports, employee feedback, inventory volumes and other data that gives them an idea of how a department accomplishes assignments. Internal Auditors attend meetings with clients and internal staff. They give reports and may serve a role in training new staff to ensure they understand how to stay compliant with legal rules and best practices.


What are the characteristics of a good Internal Auditor?

Good Internal Auditors have excellent judgment and work ethic, which allow them to identify potential risks or business violations. They are committed to ongoing learning and professional development so they can keep up with evolving industry guidelines and SEC regulations. Internal Auditors stay highly organized at all times and clearly communicate with others about how they can improve their department. Because many departments perform regular year-end audits, Internal Auditors are great at working under pressure and tracking simultaneous deadlines so that their clients can finalize business reports according to schedule.


Who does an Internal Auditor report to?

Internal Auditors have a different hierarchy than other employees because their responsibilities aren’t directly governed by their employer. Depending on the structure of the company, an Internal Auditor can report directly to the Chief Financial Officer, the Board of Directors or an external audit committee that their employer formed to limit bias. Some Internal Auditors working on large projects will report to an Internal Audit Supervisor who acts as an intermediary with senior management. Internal Auditors often report to multiple bodies in the event that they discover noncompliance or unethical information about company leadership practices.
