2027 How to Become an Internal Auditor: Education, Salary, and Job Outlook
Co-Founder and Chief Data Scientist
If you are considering internal auditing, the real question is not only whether you can review records or test controls. It is whether you want a career built around understanding how organizations work, identifying risk, improving processes, and communicating findings that leaders can act on. Internal auditors help companies, government agencies, nonprofits, healthcare systems, and other organizations protect assets, follow rules, strengthen operations, and make better decisions.
This career can suit people who like structured problem-solving, evidence-based analysis, ethical responsibility, and exposure to different parts of a business. It can also be a strong path for professionals who want options: internal auditors often move into risk management, compliance, IT audit, finance leadership, operations, or executive audit roles.
This guide explains the credentials, skills, career stages, salary expectations, internships, advancement strategies, work settings, challenges, and fit factors you should understand before pursuing internal auditing.
What are the benefits of becoming an internal auditor?
- Internal auditors enjoy a strong job outlook with a projected growth of 10% from 2023 to 2033, reflecting increased demand for risk management and compliance experts.
- Average salaries for internal auditors range from $65,000 to $85,000 annually, with potential for higher earnings as experience and certifications grow.
- Pursuing this career offers diverse opportunities across industries, fostering critical thinking and financial acumen, making it a valuable and stable profession.
What credentials do you need to become an internal auditor?
Most internal auditor roles require a bachelor’s degree, relevant business or audit knowledge, and the ability to document work clearly and ethically. Certification is not always required for entry-level jobs, but the Certified Internal Auditor credential can become important as you move into senior, manager, or leadership positions.
- Bachelor's degree: The most common starting point is a bachelor's degree from an accredited university. Accounting, finance, business, information systems, economics, and risk management are common choices, but internal audit teams also hire candidates from other disciplines when they can show strong analytical, writing, and business skills. If you are still choosing a field of study, compare majors based on the type of audit work you want to do, such as financial audit, operational audit, IT audit, compliance, or risk advisory.
- Alternative pathways: A bachelor's degree is the standard route, but it is not the only possible route. Candidates without a bachelor's degree may still qualify through at least five years of relevant internal audit experience or an internal audit practitioner designation. The Institute of Internal Auditors (IIA) also provides pathways for candidates with master's degrees or substantial professional experience. Because requirements can change, confirm the current eligibility rules directly with the certifying organization before you plan your timeline.
- CIA exam: The Certified Internal Auditor exam is a three-part exam covering internal audit fundamentals, internal audit practice, and business knowledge. Passing it shows employers that you understand audit planning, risk assessment, control testing, governance, fraud risk, communication, and professional ethics.
- Additional certifications: Internal auditors do not need a state-specific internal audit license. However, some employers may prefer or require credentials tied to their industry or audit specialty. A Certified Public Accountant (CPA) credential may help in accounting-heavy roles, while a Certified Information Systems Auditor (CISA) credential may be valuable for IT audit, cybersecurity, and systems-control work.
- Continuing education: Certification is not a one-time achievement. Maintaining the CIA credential requires continuing professional education (CPE). This matters because audit risks change quickly in areas such as cybersecurity, privacy, ESG reporting, artificial intelligence, third-party risk, and regulatory compliance.
A practical credential strategy is to start with the degree and internship experience needed for entry-level roles, then pursue the CIA once you have enough professional context to connect exam topics to real audit work.
What skills do you need to have as an internal auditor?
Internal auditors need a mix of technical judgment, business curiosity, and communication skill. The role has moved beyond checklist-style compliance work. Modern internal auditors are expected to understand risk, interpret data, evaluate controls, and explain what management should fix and why it matters.
- Data literacy: You should be comfortable working with spreadsheets, reports, transaction data, dashboards, and exceptions. Strong auditors know how to identify unusual patterns, test a sample, question incomplete data, and avoid drawing conclusions that the evidence does not support.
- Technology fluency: Audit teams increasingly use analytics platforms, workflow tools, artificial intelligence, and automated testing. You do not need to be a software engineer, but you should understand how systems process information, where errors can occur, and how technology changes the control environment.
- Cybersecurity knowledge: Even non-IT auditors need a basic understanding of access controls, segregation of duties, phishing risks, data privacy, incident response, and vendor security. For IT audit roles, deeper knowledge of system controls and security frameworks becomes more important.
- Critical thinking: Internal audit requires asking better questions, not just finding errors. You need to distinguish symptoms from root causes, recognize when a control is poorly designed, and recommend fixes that are realistic for the organization.
- Communication skills: Auditors interview employees, document evidence, write reports, and present findings to managers or executives. The best audit communication is clear, specific, and balanced: it explains the risk, the evidence, the impact, and the recommended action without exaggeration.
- Adaptability: Regulations, systems, business models, and risks change. Effective auditors adjust their approach, learn new subject matter quickly, and stay calm when an audit uncovers sensitive or unexpected issues.
- Professional skepticism and ethics: Internal auditors must be independent-minded without becoming adversarial. You need to verify information, protect confidential data, and raise concerns even when the message is uncomfortable.
If you are early in your career, focus first on Excel or spreadsheet analysis, audit documentation, interviewing, report writing, and basic risk assessment. These skills transfer across nearly every internal audit specialty.
What is the typical career progression for an internal auditor?
Internal audit has a relatively clear promotion path, but advancement depends on more than years of experience. Employers look for sound judgment, high-quality documentation, the ability to lead audits, and the confidence to communicate with management.
- Entry-Level (0-2 years): Most professionals begin as Staff Internal Auditors, Junior Internal Auditors, or Internal Audit Associates. Work typically includes assisting with audit planning, gathering evidence, testing controls, documenting results, and helping prepare reports. A bachelor's degree in accounting, finance, or a related field is essential at this stage for many employers.
- Mid-Level (3-5 years): Senior Internal Auditors usually run smaller audits or sections of larger audits with less supervision. They may design test plans, review junior staff work, identify root causes, draft findings, and interact directly with business process owners. Earning the Certified Internal Auditor (CIA) credential can improve credibility and promotion prospects.
- Advanced (6-10 years): Audit Managers or Supervisors plan audit projects, assign staff, review workpapers, manage timelines, and ensure findings are supported by evidence. They also help build the annual audit plan and coordinate with risk, compliance, finance, IT, and external auditors. Certifications such as CIA, CPA, or CISA often support advancement.
- Leadership (10+ years): Directors of Internal Audit and Chief Audit Executives set audit strategy, oversee budgets, report to executive leadership or audit committees, and align audit work with major organizational risks. At this level, technical audit knowledge must be matched with leadership, business judgment, and board-level communication skills.
Lateral moves are common and can strengthen long-term career options. Internal auditors often move into risk management, compliance, IT audit, fraud investigation, enterprise risk management, finance, operations, or CFO-track roles. The best lateral move is one that builds a specialty while preserving your broader understanding of governance, risk, and controls.
Internal auditor pay varies by experience, location, industry, employer size, certification, and audit specialty. Financial services, technology, healthcare, government contracting, and IT audit roles may pay differently from general operational audit roles, and senior positions usually require stronger leadership and reporting skills.
The internal auditor average salary in the United States ranges from about $67,000 to $93,000 annually, depending on the source. Indeed reports a higher average near $93,149, while PayScale and Salary.com place it closer to $67,000-$80,000. Entry-level roles often start between $53,000 and $57,000. Pay typically rises with experience, especially for senior auditors, audit managers, and professionals who can lead complex projects.
Certification can also affect earning potential. Internal auditors who hold Certified Internal Auditor (CIA) credentials tend to earn around $76,000 or more, reflecting the market value of specialized audit knowledge. A CIA is not a guaranteed raise, but it can strengthen your case for promotion, improve mobility, and help you compete for roles that require formal audit expertise.
When comparing internal auditor salary by experience level, consider these factors:
- Experience level: Entry-level roles pay less because they focus on testing and documentation. Senior and manager roles pay more because they require project ownership, judgment, and stakeholder management.
- Specialization: IT audit, cybersecurity, financial services, risk management, and regulatory compliance can offer stronger compensation when demand is high.
- Credentials: CIA, CPA, or CISA credentials may improve competitiveness, especially for specialized or leadership roles.
- Location: Major metropolitan areas often offer higher salaries, though cost of living can reduce the practical advantage.
- Industry: Highly regulated sectors may pay more because audit failures can carry significant financial, legal, or reputational risk.
For professionals considering advanced academic paths alongside audit or risk leadership, resources on easiest PhD programs can help compare study options, though a PhD is not typically required for internal audit practice.
Internships are one of the best ways to test whether internal audit fits your work style. A good internship exposes you to audit planning, control testing, documentation, interviews, and report preparation. It also helps you understand the difference between internal audit, external audit, compliance, accounting, and risk management.
- Large Corporations: Corporate internal audit internships often involve financial records, SOX (Sarbanes-Oxley) compliance, walkthroughs, control testing, and risk assessment. These roles are useful if you want experience with structured audit programs and large-scale business processes.
- Nonprofit Organizations and Educational Institutions: These internships may focus on grant compliance, purchasing controls, payroll processes, resource management, and operational audits. They can be a strong fit if you are interested in mission-driven organizations or public accountability.
- Government Agencies: City or state offices may hire interns to assist with regulatory audits, performance reviews, compliance testing, or process improvement. These roles can introduce you to public sector controls and governmental accounting standards.
- Healthcare Providers: Healthcare audit internships may involve patient billing, privacy compliance, claims processes, vendor controls, and operational efficiency. This is a valuable environment for learning how regulation, data, and service delivery intersect.
- Structured Programs such as the Schwab Intern Academy or Summer Analyst Roles at Financial Firms: These programs may place interns on audit teams, risk teams, or control functions. They can offer formal training, networking, mentorship, and exposure to multiple audit phases.
If you are searching for internal audit internships in New York or another competitive market, apply early and tailor your resume to audit-relevant skills: coursework in accounting or information systems, spreadsheet ability, writing, data analysis, compliance exposure, and any project where you evaluated a process or solved a business problem.
Students who need a lower-cost academic starting point can also compare cheap associate programs online before transferring or continuing into a bachelor’s degree path related to accounting, business, or information systems.
Career advancement in internal audit comes from becoming more useful to decision-makers. That means improving your technical audit work, understanding the business, communicating risk clearly, and building trust without sacrificing independence.
- Continuous learning: Use CPE courses, workshops, conferences, webinars, and employer training to strengthen skills in data analytics, cybersecurity, risk assessment, privacy, fraud, ESG reporting, and emerging regulations. Choose training that matches the audits your organization actually performs.
- Professional certifications: The Certified Internal Auditor (CIA) credential can support advancement into senior auditor, audit manager, or audit leadership roles. CPA or CISA credentials may also help depending on whether your work is accounting-heavy, systems-focused, or technology-driven.
- Building a network: Join internal audit groups, professional associations, alumni networks, and industry events. Networking helps you learn how other audit teams operate, identify job openings, and understand which skills employers are prioritizing.
- Seeking mentorship: A strong mentor can help you interpret difficult feedback, prepare for promotions, handle sensitive findings, and decide when to specialize. Look for mentors who are respected for both technical judgment and professionalism.
- Learning the business: Auditors who understand operations, revenue drivers, technology systems, and regulatory pressures make better recommendations. Volunteer for audits outside your comfort zone to build a broader view of the organization.
- Improving report quality: Clear audit reports are promotion tools. Managers notice auditors who can write concise findings, support conclusions with evidence, and recommend practical corrective actions.
One common mistake is pursuing credentials without building the judgment to use them. Certifications can open doors, but advancement depends on whether leaders trust your analysis and act on your recommendations.
Internal auditors work anywhere organizations need to manage risk, comply with rules, protect assets, and improve processes. If you are researching the best places to work as an internal auditor in Louisiana or looking at internal auditor job opportunities in Baton Rouge LA 2025, consider both local employers and larger organizations with regional, remote, or hybrid audit teams.
- Aerospace and defense: Companies like Lockheed Martin and Northrop Grumman employ auditors to support compliance with government regulations, contract requirements, procurement controls, and risk management in sensitive international contracts.
- Life sciences and pharmaceuticals: Firms such as Pfizer and Johnson & Johnson need auditors who can evaluate clinical, regulatory, manufacturing, privacy, and environmental, social, and governance (ESG) risks.
- Manufacturing and industrial: Organizations including General Electric and Ford Motor Company rely on internal auditors for supply chain controls, inventory processes, ethical sourcing oversight, operational efficiency, and cyber/IT control measures.
- Retail and consumer goods: Companies like Walmart and Amazon use internal audit teams to review payment systems, inventory controls, vendor processes, fraud risks, logistics, and secure digital infrastructure.
- Technology: Companies such as Google and Microsoft hire internal auditors to support governance, regulatory compliance, data protection, third-party risk, and technology control environments.
- Nonprofit organizations and government agencies: Organizations such as the US Department of Defense offer audit roles focused on public funds, policy compliance, program performance, procurement, and accountability.
- Healthcare systems, educational institutions, and major corporations: These employers need auditors to monitor compliance, billing, purchasing, privacy, grants, payroll, financial reporting, and operational risk.
When comparing employers, look beyond the job title. Review the audit department’s size, reporting structure, travel expectations, technology tools, promotion history, and whether the role focuses on financial controls, operational audits, IT audit, compliance, or enterprise risk. For students or career changers, accredited online universities offering free applications may help reduce upfront application costs while you build qualifications for audit-related roles.
Internal audit can be rewarding, but it is not always comfortable. Auditors often work under deadlines, review sensitive issues, and deliver findings that managers may not want to hear. The challenge is to stay objective, accurate, and constructive.
- Expansive knowledge requirements: Internal auditors must keep up with changing regulations, business processes, cybersecurity, privacy, ESG reporting, artificial intelligence, fraud risks, and industry-specific rules. No auditor knows everything, so knowing when to bring in subject-matter expertise is important.
- Adapting to AI impact: Automation can reduce repetitive testing and improve data analysis, but it also changes the risks auditors must evaluate. Auditors need to understand what AI tools do, where bias or errors may appear, and how to verify automated outputs.
- Managing heavy workloads with limited resources: Audit teams often face tight timelines, budget limits, competing priorities, and talent shortages. Strong prioritization matters because not every risk can receive the same level of testing.
- Handling organizational dynamics: Auditors may need to interview defensive employees, challenge long-standing practices, or report weaknesses involving influential managers. Professionalism, preparation, and evidence-based communication help reduce conflict.
- Building trust and influence: Internal audit is most effective when business leaders see auditors as objective advisors, not just rule enforcers. Trust grows when findings are fair, recommendations are practical, and auditors understand business realities.
- Maintaining independence: Internal auditors work inside the organization but must still assess issues objectively. This can be difficult when relationships, politics, or pressure to soften findings affect the audit environment.
The most successful auditors learn to be firm on evidence and flexible on solutions. They do not ignore risk, but they also avoid impractical recommendations that the organization cannot implement.
To excel as an internal auditor, build habits that make your work reliable, useful, and respected. Technical knowledge matters, but consistency, judgment, and communication often separate average auditors from high-performing ones.
- Prioritize ongoing education because nearly 40% of core auditing skills will change by 2030. Focus on data analytics, AI applications, cybersecurity, risk assessment, and control design.
- Write better audit reports. A strong finding clearly states the condition, criteria, cause, risk, and recommended action. Avoid vague language and unsupported conclusions.
- Prepare carefully for interviews. Know what process you are testing, what evidence you need, and which questions will help confirm how the process actually works.
- Seek mentorship from experienced auditors who can review your work, explain audit politics, and help you understand how to move from testing tasks to audit leadership.
- Expand your professional network by connecting with colleagues in finance, IT, operations, compliance, and risk. Internal audit depends on understanding how different functions operate.
- Volunteer for diverse projects. Rotating through operational, financial, compliance, and IT audits can make you more versatile and help you choose a specialty.
- Build critical thinking, adaptability, and resilience. You will encounter incomplete data, changing priorities, and difficult conversations. A calm, evidence-driven approach protects your credibility.
- Learn from every audit closeout. Ask what caused delays, which tests worked, which findings were strongest, and how the next audit can be more efficient.
A useful rule is to make every audit deliver more than a list of problems. The best auditors help leaders understand risk, prioritize fixes, and strengthen the organization.
Internal auditing may be a good fit if you enjoy investigating how systems work, asking careful questions, and using evidence to improve decisions. It may be less satisfying if you dislike documentation, uncomfortable conversations, or work that requires patience with details.
- Curiosity: Internal auditors need to look beyond surface-level explanations. If you naturally ask “How do we know this is working?” or “What could go wrong here?” the role may fit your mindset.
- Communication skills: The job requires clear writing, careful listening, and the confidence to explain findings to employees, managers, and executives. You must be able to challenge assumptions without becoming hostile.
- Work style preferences: Approximately 70% of internal auditors have detail-focused, sensing personalities, notably ESTJ and ISTJ types. Personality type should not be treated as a requirement, but people who enjoy systematic, logical, and disciplined work often find the role more comfortable.
- Lifelong learning: Internal audit changes as regulations, technology, business models, and risks change. If you prefer a career where you can master one fixed body of knowledge and stop learning, this field may feel demanding.
- Integrity and trustworthiness: Auditors handle confidential information and may identify problems that affect reputations, budgets, or leadership decisions. Ethical judgment is central to the profession.
- Tolerance for ambiguity: Not every audit produces a simple answer. You may need to make reasonable conclusions from incomplete evidence while documenting your reasoning carefully.
If you are asking, is internal auditing the right career for me, consider shadowing an auditor, applying for an internship, taking an accounting or information systems course, or trying a process-improvement project. Direct exposure will tell you more than a job description.
Career suitability for internal auditors also depends on your credential goals and earning expectations. If you are comparing short-term credentials in related fields, resources on what certifications pay well can help you evaluate options, though you should choose credentials based on your target role rather than salary alone.
