Accountants measure and report financial information for individuals and businesses. Although most accountants work in public practices servicing many clients, many larger companies also have their own internal accounting departments. Individuals and small businesses often use accountants to prepare their annual tax returns and bookkeeping. Certified public accountants (CPAs) can also provide financial advice and assist with tax audits. Enrolled Agents (EAs) are recognized by the U.S. government to represent clients in dealings with the Internal Revenue Service (IRS).
