CPA vs. accountant vs. enrolled agent

A Certified Public Accountant (CPA) has passed the Uniform CPA Exam and holds an active state license, and can perform audits, attest work, and complex tax planning. A general accountant may handle bookkeeping and returns without that license. An Enrolled Agent (EA) is federally licensed by the IRS and specializes in tax and IRS representation. For audited financials or attest services you need a CPA; for most tax filing, a CPA or EA both qualify.
