The short version of EA vs CPA: an Enrolled Agent is a federally licensed tax specialist with unlimited rights to represent taxpayers before the IRS, and a Certified Public Accountant holds a state-issued license that covers tax work plus audits, financial reporting, and consulting. Both can prepare returns and fight an IRS dispute on your behalf. The practical difference is scope. If your need is purely tax, an EA is often the better match and usually costs less. If you need audited financials, assurance work, or broad business advisory services, only a CPA can do that work.
Where the Authority Comes From
The EA credential is issued by the IRS and is the highest credential the IRS awards.1Internal Revenue Service. Enrolled Agent Information Because it’s federal, an EA can practice in all 50 states and U.S. territories with no additional state licensing. One EA can serve a client in Florida and a client in Oregon without extra paperwork.
A CPA license comes from a state Board of Accountancy, and each state sets its own education, examination, and experience rules.2National Association of State Boards of Accountancy. Boards of Accountancy Most states have mobility rules that let a CPA licensed elsewhere serve clients across state lines under certain conditions.3National Association of State Boards of Accountancy.

What an Enrolled Agent Can Do
An EA’s work is taxation, start to finish. That covers preparing individual, corporate, partnership, estate, and gift returns, plus unlimited representation before the IRS. “Unlimited” means any taxpayer, any type of tax matter, any IRS function — examination, collection, appeals.1Internal Revenue Service. Enrolled Agent Information That includes negotiating audit outcomes, requesting penalty abatement, and submitting an Offer in Compromise.
The authority for this comes from Treasury Department Circular 230, the same rulebook that governs attorneys and CPAs when they practice before the IRS.4Internal Revenue Service. Office of Professional Responsibility and Circular 230 Under Circular 230, an EA in good standing can practice before the IRS to the same extent as an attorney or CPA.5eCFR. 31 CFR 10.3 – Who May Practice
What an EA cannot do: non-tax accounting work. No financial statement audit, no review report for a bank, no attestation engagement. The scope is narrow by design, but inside taxation it runs as deep as any credential available.
What a CPA Can Do
A CPA can handle everything an EA can on the tax side, and more beyond it. The exclusive advantage is attestation: audits, reviews, and related engagements that provide independent assurance on a company’s financial statements. If a bank, a buyer, or an investor needs audited financials, only a licensed CPA can sign the opinion. No other credential opens that door.
Audits provide the highest level of assurance, expressing an opinion on whether the 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 keep a CPA firm on retainer as a general financial advisor.
One nuance worth keeping in mind: a CPA whose practice centers on auditing or consulting may not spend as much daily time in the tax code as an EA who does nothing else. The credential tells you what someone is authorized to do, not necessarily what they do every day.
Tax Court Is a Separate Door
Both EAs and CPAs can represent you before the IRS. Representation in the U.S. Tax Court is a different question. Tax Court is a federal court, and non-attorneys who want to practice there must pass a written examination administered by the Court covering Tax Court rules of practice and procedure, the Federal Rules of Evidence, federal taxation, and legal ethics, with a passing score of 70 percent in each subject area.6United States Tax Court. Procedures for Preparation and Grading of the Nonattorney Examination Passing the exam doesn’t guarantee admission; the Court also weighs moral character.
Attorneys admitted in any state can apply for Tax Court admission without the exam. For most everyday tax disputes that stay inside the IRS administrative process, none of this matters. It matters when a taxpayer wants to contest a deficiency notice in court rather than through IRS Appeals.
What It Takes to Earn Each Credential
Enrolled Agent
The EA path is built around demonstrated tax knowledge. The IRS requires no college degree and no prior work experience. The core requirement is passing the three-part Special Enrollment Examination, which covers Individuals; Businesses; and Representation, Practices and Procedures. Passing scores are valid for three years, and all three parts must be passed within that window.7Internal Revenue Service. Publication 5279 – Enrolled Agent Requirements
After passing, the candidate obtains a Preparer Tax Identification Number, applies for enrollment, and pays a $140 fee.8eCFR. 26 CFR 300.5 – Enrollment of Enrolled Agent Fee A suitability check follows, including tax compliance and a criminal background review. Outstanding tax liabilities without an acceptable payment arrangement, unfiled returns, or a felony involving federal tax law or dishonesty within the past ten years can disqualify an applicant.9Internal Revenue Service. Enrolled Agents – Frequently Asked Questions A separate path through prior IRS employment exists, though the exam route is far more common.
CPA
CPA licensure has three components: education, examination, and experience. 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 additional model pathways, including a newer 120-hour pathway that substitutes an extra year of professional experience for the extra coursework, and several states have adopted the alternative to address the accounting talent shortage.10National 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 take three core sections plus one discipline section of their choice.11AICPA & CIMA. Navigating CPA Evolutions New Model for the CPA Exam All sections must be passed within 30 months of the first one, though some states allow up to three years.12AICPA & CIMA. Find Out When Youll Get Your CPA Exam Score Candidates also complete supervised work experience, typically one to two years depending on the state and pathway, verified by a licensed CPA.
The upshot: CPA licensure is longer and more demanding, which is a large part of why CPA billing rates tend to run higher.
What Confidentiality Actually Covers
A common misconception is that anything you tell your tax professional is automatically privileged. Under 26 U.S.C. § 7525, communications between a taxpayer and a federally authorized tax practitioner receive the same confidentiality protections that would apply to an attorney, but only for tax advice and only in two settings: noncriminal tax matters before the IRS, and noncriminal tax proceedings in federal court.13Office of the Law Revision Counsel. 26 USC 7525 – Confidentiality Privileges Relating to Taxpayer Communications
The privilege applies equally to EAs and CPAs when they are giving tax advice. It has real gaps. It does not apply in criminal tax investigations, state proceedings, or communications related to tax shelter promotion.13Office of the Law Revision Counsel. 26 USC 7525 – Confidentiality Privileges Relating to Taxpayer Communications If criminal exposure is on the table, the stronger attorney-client privilege that comes with hiring a tax attorney may be worth the additional cost. An EA or CPA providing non-tax services like bookkeeping or business consulting has no statutory privilege protecting those communications at all.
Who Disciplines Them
Any practitioner who practices before the IRS, including EAs, CPAs, and attorneys, falls under the IRS Office of Professional Responsibility (OPR). The OPR enforces Circular 230 and can impose censures, suspensions, or disbarment from IRS practice.14Internal Revenue Service. Search for Disciplined Tax Professionals The IRS maintains a public database of disciplinary actions going back 25 years, which is worth searching before you sign an engagement letter.
CPAs face an additional layer: the state Board of Accountancy. State boards can suspend or revoke a CPA license for reasons that go beyond tax practice, including gross negligence in audit work, breach of client confidentiality, fraud, or felony convictions. A state board revocation strips the CPA of the right to practice public accounting in that jurisdiction. Because EAs hold a federal credential rather than a state license, their disciplinary exposure for tax-related misconduct runs through the OPR rather than a state board.
Which One to Hire
For straightforward tax preparation and IRS representation, an EA is often the better fit. The entire practice revolves around taxation, so the person handling your return likely spends every day in the tax code. An EA who focuses on small business returns may have more hands-on Schedule C experience than a CPA at a firm that mostly does audits.
Hire a CPA when you need services beyond tax: audited financial statements for a bank loan, reporting for investors, forensic accounting during a dispute, or broad business advisory work. The CPA is also the right choice if you want one firm handling tax, bookkeeping, and financial statement preparation under a single roof.
Cost is a practical factor. EAs tend to charge lower hourly rates than CPAs, reflecting the difference in credentialing and the narrower service menu. The gap closes when the comparison is an EA against a CPA who specializes exclusively in tax, since both bring deep tax expertise. For complex IRS disputes like audits, collections, or appeals, both carry the same unlimited representation rights, and the individual practitioner matters more than the letters after the name.1Internal Revenue Service.
