An Enrolled Agent (EA) is a federally licensed tax specialist with unlimited rights to represent taxpayers before the IRS, while a Certified Public Accountant (CPA) holds a state-issued license covering a much broader range of accounting work, including audits and financial reporting. The practical question in EA vs. CPA comes down to what you need done: for tax preparation and IRS disputes, an EA is usually the tighter fit; for audited financial statements or wider business advisory work, only a CPA will do.
What Each Professional Is Authorized to Do
The Enrolled Agent
An EA’s practice begins and ends with taxation. They prepare individual, corporate, partnership, estate, and gift tax returns, and their defining authority is unlimited representation before the IRS. “Unlimited” here means any taxpayer, any type of tax matter, and any IRS office, from examination and collection through appeals.1Internal Revenue Service. Enrolled Agent Information That covers negotiating audit settlements, requesting penalty abatement, and submitting an Offer in Compromise.
This authority comes from Treasury Department Circular 230, the same rulebook that governs attorneys and CPAs when they practice before the IRS.2Internal Revenue Service. Office of Professional Responsibility and Circular 230 Under Circular 230, an enrolled agent in good standing may practice before the IRS to the same extent as an attorney or CPA.3eCFR. 31 CFR 10.3 – Who May Practice
What the EA credential does not authorize is non-tax accounting work. An EA cannot perform a financial statement audit, issue a review report for a company seeking bank financing, or sign off on an attestation engagement. The scope is narrow, but within taxation it runs as deep as any credential available.
The CPA
A CPA can do everything an EA can do on the tax side, and much more beyond it. The defining advantage is the exclusive right to perform attestation services: audits, reviews, and related engagements that provide independent assurance on a company’s financial statements. If your business needs audited financials for a bank loan, a merger, or a securities offering, only a licensed CPA can sign that opinion.
Audits provide the highest level of assurance, expressing an opinion on whether financial statements are fairly presented. Reviews provide limited assurance through analytical procedures and inquiries. Both require a CPA license. Beyond attestation, CPAs work in management consulting, forensic accounting, internal controls, and business valuation. That breadth is why many businesses retain a CPA firm as a one-stop financial advisor.
One caveat worth keeping in mind: a CPA whose career centers on auditing or consulting may not have the same day-to-day immersion in tax law as an EA who does nothing else. The letters after someone’s name tell you what they’re authorized to do, not necessarily what they specialize in.
Federal License vs. State License
The EA credential is granted by the IRS and is the highest credential the IRS awards.1Internal Revenue Service. Enrolled Agent Information Because the authority is federal, an EA can practice in all 50 states and U.S. territories without any additional state licensing. A client in Florida and a client in Oregon can use the same EA with no extra paperwork.
A CPA license is issued by a state Board of Accountancy, and each state sets its own education, examination, and experience requirements.4National Association of State Boards of Accountancy. Boards of Accountancy Most states have adopted mobility legislation that lets a CPA licensed in one state serve clients in another under certain conditions.5National Association of State Boards of Accountancy. CPAMobility.org Helps CPAs Work Seamlessly Across State Lines Even so, the underlying authority is state-based, and a CPA who lets a license lapse or faces discipline in one state may not be able to lean on mobility rules elsewhere.
What It Takes to Earn Each Credential
Becoming an EA
The EA path is built around demonstrated tax knowledge rather than formal education. The IRS does not require a college degree or prior work experience. The core requirement is passing the Special Enrollment Examination, a three-part test covering Individuals, Businesses, and Representation, Practices and Procedures. Passing scores are valid for three years, and all three parts must be passed within that window.6Internal Revenue Service. Publication 5279 – Enrolled Agent Requirements
After passing, the applicant obtains a Preparer Tax Identification Number, applies for enrollment, and pays a $140 fee.7eCFR. 26 CFR 300.5 – Enrollment of Enrolled Agent Fee The IRS also runs a suitability check that includes tax compliance and a criminal background review. Outstanding tax liabilities without an acceptable payment arrangement, unfiled returns, or a felony conviction involving federal tax law or dishonesty within the past ten years can disqualify an applicant.8Internal Revenue Service.

Becoming a CPA
CPA licensure has three parts: education, examination, and experience. Each is more demanding than the EA equivalent.
The traditional education requirement is 150 semester hours of college credit, which is 30 hours beyond a standard bachelor’s degree and typically means a fifth year of school or a master’s program. NASBA now recognizes three model pathways, including a newer 120-hour pathway that substitutes an additional year of professional experience for the extra coursework, and multiple states have adopted or are considering that alternative.9National Association of State Boards of Accountancy. New CPA Licensure Pathways and CPA Mobility
The Uniform CPA Examination, administered by the AICPA, was restructured in 2024 under the CPA Evolution model. Candidates now take three core sections and one discipline section of their choice.10AICPA & CIMA. Navigating CPA Evolutions New Model for the CPA Exam Candidates also complete supervised work experience, typically one to two years depending on the state and the pathway chosen, verified by a currently licensed CPA. Only after all three components are satisfied does the state board issue the license.
Keeping Each Credential Active
Enrolled Agents must complete 72 hours of continuing education every three-year enrollment cycle, including at least 6 hours of ethics, with a minimum of 16 hours per year and at least 2 ethics hours annually.11Internal Revenue Service. Maintain Your Enrolled Agent Status CPA continuing education requirements vary by state. Most states require between 80 and 120 hours over a two- or three-year cycle, often with specific ethics and technical rules, and a CPA practicing across multiple jurisdictions has to track each state board’s requirements.
Confidentiality and Discipline
Under 26 U.S.C. ยง 7525, communications between a taxpayer and a federally authorized tax practitioner get the same confidentiality protection that would apply if the practitioner were an attorney, but only for tax advice and only in two contexts: noncriminal tax matters before the IRS and noncriminal tax proceedings in federal court.12Office of the Law Revision Counsel. 26 USC 7525 – Confidentiality Privileges Relating to Taxpayer Communications
This privilege applies equally to EAs and CPAs when they’re giving tax advice, but it has real gaps. It does not apply in criminal tax investigations, state proceedings, or communications related to tax shelter promotion.12Office of the Law Revision Counsel. 26 USC 7525 – Confidentiality Privileges Relating to Taxpayer Communications If you face potential criminal exposure, the stronger attorney-client privilege that comes with hiring a tax attorney may be worth the added cost. An EA or CPA providing non-tax services such as bookkeeping or business consulting has no statutory privilege protecting those communications at all.
Both credentials answer to the IRS Office of Professional Responsibility (OPR), which enforces Circular 230 and can censure, suspend, or disbar practitioners from IRS practice. The IRS maintains a public database of disciplinary actions going back 25 years, so you can check whether a practitioner has been sanctioned before hiring them.13Internal Revenue Service. Search for Disciplined Tax Professionals CPAs face an additional layer through their state board, which can suspend or revoke a license for reasons that go beyond tax practice, including gross negligence in audit work, breach of client confidentiality, fraud, or felony convictions.
Which One Should You Hire
For straightforward tax preparation and IRS representation, an EA is often the better fit. Their entire practice revolves around taxation, so the person handling your return likely spends all day, every day, working with the tax code. An EA who focuses on small business returns, for instance, may have more hands-on experience with Schedule C issues than a CPA whose firm primarily does auditing.
Hire a CPA when you need services beyond tax: audited financial statements for a bank loan, financial reporting for investors, forensic accounting during a dispute, or broader business advisory work. The CPA is also the right call if you want a single firm handling your tax compliance, bookkeeping, and financial statement preparation under one roof.
Cost matters too. EAs tend to charge lower hourly rates than CPAs, reflecting the difference in credentialing requirements and the wider service menu CPAs offer. The gap narrows when you compare an EA to a CPA who specializes exclusively in tax, since both bring deep tax expertise. For complex IRS disputes such as audits, collections, or appeals, both carry the same unlimited representation rights, and the quality of the individual practitioner matters more than the letters after their name.1Internal Revenue Service.
