What Does an Auditor Do?

An auditor examines financial information and related controls to determine whether records are reliable and follow applicable standards. The auditor plans the review around areas where errors or omissions could matter, then gathers and evaluates evidence. The auditor documents findings and reports conclusions to the people who need them, such as organizational leaders or users of financial statements. This work helps organizations and stakeholders understand the quality of reported information and identify weaknesses that may need attention.

What Is a Auditor?

An auditor is a professional who independently examines records, processes, or programs against defined criteria. The work may focus on financial statements, internal controls, compliance, or operational performance. External auditors assess financial statements for outside users, while internal auditors examine risks and processes within their organization. Government auditors may review public entities or programs, including whether public funds are used appropriately. For government engagements, the Government Auditing Standards provide standards for financial audits, attestation engagements, and performance audits.

An audit is based on evidence collected for a specific purpose. In a financial statement audit, the auditor gives an opinion on whether the statements are presented fairly in all material respects under the relevant reporting framework. That opinion is not a guarantee that every transaction is correct or that all fraud has been detected.

What Are the Main Responsibilities of a Auditor?

Auditors first learn how the organization operates and how it creates the information under review. They use that understanding to identify areas where a material error, omission, or failure to follow a requirement could occur. That assessment shapes the audit plan, including which records to examine and what evidence would address the identified risks.

During testing, auditors compare recorded information with supporting evidence. For example, an auditor checking a recorded payment might trace it to an invoice and approval record. Auditors generally select transactions for testing rather than review every entry. When evidence conflicts or a result is unexpected, they investigate the discrepancy instead of relying on an explanation alone.

Auditors also evaluate relevant controls, such as approval procedures intended to prevent unauthorized payments. They assess whether a control is designed to address a risk and whether it appears to operate as intended. A weakness may lead to additional testing or a recommendation for corrective action, but the weakness by itself does not establish that the financial statements are wrong.

As the work concludes, auditors assess whether the evidence supports their findings and conclusions. They document the procedures performed and communicate issues to the appropriate recipients. O*NET describes examining financial records, analyzing data, identifying control deficiencies or noncompliance, and reporting findings among the work associated with accountants and auditors.

What Does a Auditor Do on a Daily Basis?

A typical day often begins with reviewing the audit plan and checking what evidence has arrived from the organization. The auditor may then examine selected transactions or compare financial data with supporting records. If an amount does not agree, the auditor follows the trail through source documents and accounting entries to understand where the difference arose.

Later, the auditor may meet with staff who handle the process being reviewed to clarify how it works in practice. The auditor records the explanation, compares it with available evidence, and decides whether additional testing is needed. Before finishing, the auditor updates working papers so another reviewer can understand the work and its basis. The sequence varies with the audit’s purpose and deadlines, and some assignments include visits to client or agency locations.

What Skills Does a Auditor Need?

Analytical thinking helps auditors identify patterns that may need further examination. For example, a sharp change in a balance from one period to the next can prompt questions about the underlying transactions. The change is a lead for follow-up, not proof of an error.

Attention to detail matters when matching recorded amounts to supporting evidence. Auditors need to distinguish a small discrepancy from one that could affect a significant conclusion. Clear writing is also important because working papers and reports must explain what was tested, what the evidence showed, and why a finding matters.

Communication helps auditors obtain information without losing sight of the audit objective. They may need to ask focused questions about a process and then explain a concern in a way that the responsible team can act on. O*NET identifies critical thinking as an important skill for accountants and auditors because the work involves interpreting information and reaching conclusions.

How Much Does a Auditor Earn?

The U.S. Bureau of Labor Statistics reports a median annual wage of $81,680 for accountants and auditors in May 2024. This figure covers the combined occupational group rather than auditors alone, so it should not be treated as a pay figure specific to every auditor role. The median means half of workers in that group earned more and half earned less. See the Bureau of Labor Statistics occupational profile for the wage figure and occupational details.

What Is the Career Progression for a Auditor?

Auditors commonly begin by carrying out assigned testing and documenting the evidence they review. With experience, they may handle more complex areas, help plan engagements, or review the work of less experienced colleagues. In public accounting, a potential path can lead to supervising engagements and managing client relationships. Within an organization, an internal auditor may develop deeper expertise in a particular risk area or move into audit leadership.

Education and credential expectations depend on the position and the kind of audit work. A bachelor’s degree in accounting or a related field is common preparation, but the title “auditor” does not establish one universal requirement. Some external audit responsibilities require a CPA license, while other auditor positions may not. Candidates should check the requirements for the specific role and jurisdiction.

How Contingent Workforce Management Helps Businesses Hire Auditors

Contingent workforce management services help companies arrange and administer temporary or project-based workers. A business facing a reporting deadline may need an auditor for a defined period to test selected transactions and document evidence. If the company has identified a worker directly, hiring that worker through an appropriate arrangement and using third-party payrolling can be a lower-cost alternative to a staffing agency.

TCWGlobal helps companies manage contingent auditors through payrolling and workforce support for the assignment. For a time-limited audit project, this can reduce the company’s recruiting expense when it has already found the worker. It can also reduce administrative work associated with onboarding, time tracking, and payroll while the audit team focuses on its review.
