CPA vs Enrolled Agent: Scope, IRS Representation Rights and Requirements

A CPA and an enrolled agent (EA) can both represent a taxpayer before the IRS on any matter. That is where the overlap ends. A CPA is licensed by a state board and can also perform attest work. An EA is enrolled by the IRS and works in tax. This guide sets the two side by side as of November 2026, using the regulation text and IRS pages, so audit and accounting professionals can decide which credential fits the work, or whether to hold both.

What is the core difference?

The IRS calls enrolled agent status "the highest credential the IRS awards."

What does Circular 230 say about who can represent taxpayers?

Circular 230, codified at 31 CFR Part 10, governs practice before the IRS. Section 10.3 lists who may practice:

• Attorneys not under suspension or disbarment may practice by filing a written declaration that they are qualified and authorized to represent the party.
• Certified public accountants are covered by the same rule: not suspended or disbarred, with a written declaration of qualifications and authority.
• Enrolled agents, defined as any individual enrolled as an agent under Part 10 and not suspended or disbarred, may practice, and no declaration is required.
• Enrolled actuaries, enrolled retirement plan agents and registered tax return preparers are covered in other paragraphs with limited scope. For example, registered tax return preparers are limited to preparing and signing returns and related documents, and enrolled retirement plan agents to specified retirement plan programs.

The IRS describes enrolled agents as having unlimited practice rights, the same as attorneys and CPAs: they can represent any taxpayer, handle any type of tax matter, and appear before any IRS office. The FAQ adds that enrolled agents are generally unrestricted on which taxpayers, matters and IRS offices they can handle.

So for IRS audits, collections and appeals, the credentials carry equal federal rights. Circular 230's duties apply to both: diligence, standards for returns and documents, competence, and sanctions enforced by the IRS Office of Professional Responsibility. A violation can lead to sanctions on the federal side regardless of state license status.

Circular 230 covers practice before the IRS only. Representation before a state tax agency follows that state's own rules, so check the state before assuming federal rights carry over.

Confidentiality privilege

Internal Revenue Code section 7525 extends the attorney-client style confidentiality protection to communications with a federally authorized tax practitioner, which is any individual authorized under federal law to practice before the IRS. It covers tax advice only, and it can be asserted only in noncriminal tax matters before the IRS and in noncriminal tax proceedings in federal court brought by or against the United States. It does not protect written communications relating to promoting participation in a tax shelter. Because section 7525 turns on federal authorization to practice, both CPAs and EAs fall within the definition when practicing under Circular 230.

What can a CPA do that an EA cannot?

Attest. State accountancy laws reserve audit and review reports to licensed CPAs and CPA firms, and the licensed CPA signs the report. An EA does not have that authority. Each state sets its own rules on which other accounting services non-licensees may perform. If your career is in audit, EA does not take the place of the license. See what an auditor does, the differences between audit, review and compilation and independence and nonattest services.

A CPA firm that prepares returns for attest clients carries independence obligations as well as tax-practice duties. The CPA license ties you to the AICPA's Code of Professional Conduct through state rules and, for members, the AICPA.

What are the requirements for each?

CPA

Education, the four-section exam, experience and (in many states) ethics, set state by state. See how to become a CPA and the CPA Exam sections guide. Rules differ by state; the state hub is a place to start.

Enrolled agent

The IRS steps, in order:

1. Obtain a Preparer Tax Identification Number (PTIN).
2. Pass all three parts of the Special Enrollment Examination (SEE) within three years.
3. Apply for enrollment on Form 23 and pay the fee. The IRS says to apply within one year of passing the third part.
4. Pass a suitability check covering tax compliance and a criminal background check.

Under 31 CFR 10.4 the applicant must be at least 18, pass the written exam, hold a PTIN and not have engaged in conduct that would justify suspension or disbarment. Section 10.4 sets no education requirement. Some former IRS employees qualify without the exam: for enrolled agents, five years of continuous IRS employment applying and interpreting the Internal Revenue Code and regulations, or ten aggregate years in such positions with at least three in the five years before applying, and they must apply within three years of leaving the IRS.

The SEE

• Parts: Part 1 Individuals, Part 2 Businesses, Part 3 Representation, Practices and Procedures. You can take them in any order.
• Questions: 100 per part, of which 85 are scored and 15 are experimental and unscored.
• Time: 3.5 hours per part, with a four-hour seat time that covers a tutorial, a survey and two 10-minute breaks.
• Scoring: Scaled 200 to 800, passing 500. Passing candidates see a pass designation without a number.
• Attempts: Up to four times per part per testing window, which runs from May 1 to the end of February. After a failed part you must wait 24 hours before scheduling the same part again.
• Credit: Passing scores carry over up to three years from the pass date.
• Vendor: The IRS names PSI Services as the exam vendor effective March 1, 2026.
• Fees: $317 per part at scheduling, non-refundable and non-transferable, and $140 to enroll with Form 23.

Illustrative arithmetic from those IRS figures: three parts at $317 is $951, and adding the $140 enrollment fee makes $1,091 in IRS-published fees, before study materials or the PTIN fee. Testing time is 3 × 3.5 = 10.5 hours against 16 hours for the CPA Exam.

The suitability check

The IRS says overdue unfiled returns or unpaid taxes can count against an applicant unless there is an acceptable payment arrangement. Felony convictions under federal tax law, or felonies involving dishonesty or breach of trust, can count against an applicant if less than ten years old. The standard is in Circular 230 sections 10.5(d)(1) and 10.51.

What about continuing education?

EAs complete 72 hours in each three-year enrollment cycle, with at least 16 hours each year, including 6 ethics hours over the cycle and at least 2 per year. EA courses must focus on federal taxation or related matters and be consistent with the Internal Revenue Code. EAs renew on a three-year cycle tied to the last digit of the Social Security or tax identification number, and renew the PTIN annually.

CPAs owe CPE under their state board's rules, and many boards add an ethics course; see CPE. The two programs count different things, so one course may or may not satisfy both. Check each body's definitions.

Can you hold both?

Section 10.3 lists each category separately, so a CPA's right to practice does not depend on enrollment. A CPA who enrolls as an agent gains no extra IRS representation rights, because 10.3(b) already covers CPAs. Anyone who prepares federal returns for pay needs a PTIN whatever credential they hold.

How should you choose?

• You want to sign audits, reviews or compilations: CPA. Nothing else substitutes.
• Your work is tax return preparation and IRS representation only, and you want a federal credential: EA is a direct route and requires no degree, though many EAs hold one.
• You work in audit and want to move toward tax: The CPA Exam's REG section and the TCP discipline test tax. See the exam sections guide.
• You already hold a CPA: Representation rights are already in place. See the IRS Practitioner Priority Service guide for working with the IRS.

Frequently asked questions

Is an enrolled agent a CPA?

No. A CPA is licensed by a state board and can perform attest work. An EA is enrolled by the IRS and practices in tax.

Can an enrolled agent represent clients before the IRS?

Yes. The IRS describes EAs as having unlimited practice rights, the same as attorneys and CPAs, so they can represent any taxpayer, on any type of tax matter, before any IRS office.

Does an enrolled agent need a college degree?

The enrollment rule in 31 CFR 10.4 sets no education requirement. The applicant must be at least 18, pass the exam, hold a PTIN and meet the suitability standard.

How hard is the Special Enrollment Examination?

It has three parts of 100 questions each, with a scaled passing score of 500 on a 200 to 800 scale, and each part can be tried up to four times per testing window.

Can an enrolled agent sign an audit report?

No. Attest reports are reserved to licensed CPAs and CPA firms under state law.

Do CPAs and enrolled agents both need a PTIN?

Yes, when they prepare returns for pay. The IRS says anyone who prepares or helps prepare federal returns for pay must have one, and all enrolled agents must hold one.
