How to Become an Auditor

Most people have heard of accountants. But what is an auditor? And what does an auditor do differently from an accountant? Like accountants, auditors work closely with financial documents. Auditors review these documents to find errors and advise clients to correct them. Some specialize in fraud detection.

The career path requires a bachelor’s degree in accounting, business, or a related field. Auditors also need strong analytical skills and an attention to detail. Our guide explains how to become an auditor, including a step-by-step route to career advancement.

Sometimes called IRS auditors in the U.S., these professionals work in external auditing for a federal or state government.

A bachelor’s degree helps auditors launch their career. Some pursue specialized training with a graduate degree. Accountants and business professionals looking for a career change may find auditing a good fit.
