How to Become an Internal Audit Manager

Begin with a bachelor’s degree in accounting, finance, business administration, economics, or a related field—approximately 60–65% of job postings require it, and it serves as the primary gateway into auditing roles. From there, build practical experience: begin in roles like internal auditor or external audit assistant, or even through internships or graduate trainee schemes, where you can rotate into audit teams.

Once you’re working in audit, pursue professional certifications such as Certified Internal Auditor (CIA), Certified Public Accountant (CPA), or Certified Information Systems Auditor (CISA)—these are widely regarded as key differentiators. An optional but beneficial step is earning a master’s degree (e.g., MAcc or MBA), particularly if you’re targeting regulated industries or leadership.

Next, progress from senior auditor to audit supervisor or team lead, gaining experience in planning and supervising internal audits. Typically, you’ll need 5–8 years of related experience—including several years as a leader—before stepping into the manager role.

Profile & Purpose

An internal audit manager serves as both custodian and champion of a company’s internal control environment. Reporting to the head of internal audit or, occasionally, the audit committee, this role combines assurance and advisory work, involving conducting risk-based reviews, enhancing internal controls, and guiding remediation efforts. You ensure compliance with regulations, champion ethical standards, and support business performance through objective, value-added audits.

Responsibilities

Internal audit managers oversee the end‑to‑end audit cycle. You’ll develop the annual audit plan, prioritising high-risk areas; manage audit teams through planning, fieldwork, and report writing; and present clear findings and remediation plans to senior management. A critical task is coordinating with external auditors to ensure alignment of audit objectives and avoid duplication of efforts. The role also involves mentoring staff, monitoring follow-up actions, and occasionally leading investigations or SOX compliance testing, depending on the organisation’s focus.

Skills & Expertise

In addition to strong technical capabilities—such as risk-based audit methodology, internal control evaluation, and familiarity with auditing standards—the ideal manager excels in communication, translating complex findings into actionable insights. You need sharp analytical thinking and problem-solving skills, with a keen eye for detail. Project management matters too: managing audit timelines, resources, and deliverables efficiently.

Equally vital are leadership and integrity. You must lead teams ethically, foster independence, and build trust across functions. Gaining respect often depends on demonstrating objectivity, resilience, and the ability to influence without direct authority.

Qualifications & Experience

Most internal audit manager roles demand:

• A bachelor’s degree in a relevant discipline – accounting or finance – is preferred.
• Professional credential(s): CIA, CPA, CISA, or CFE—these significantly boost credibility.
• A master’s degree (e.g., MAcc or MBA) is not mandatory but is highly beneficial for senior roles.
• Typically 5–8 years in auditing roles, with at least 2–3 years in supervisory or team leadership positions.
• Experience across financial, operational, IT, and compliance audits—including SOX or ESG reviews—helps you stand out.

Career Progression

The typical career path flows from internal auditor → senior auditor → audit supervisor → internal audit manager, and on to head of internal audit or chief audit executive (CAE). The CAE often reports directly to the board or audit committee, ensuring independence and strategic influence.

Final Thoughts

Becoming an internal audit manager requires a solid foundation of education, rigorous audit experience, respected certifications, and refined leadership skills. Your role blends technical excellence with strategic thinking, mentorship, and ethical guidance.

To excel, focus on acquiring broad audit exposure (financial, operational, and IT), gaining certifications like the CIA or CISA, demonstrating people leadership, and consistently translating audit findings into business value. That combination sets you on the path to senior roles—overseeing risk and controls at the highest level.
