The CPA vs enrolled agent question usually gets answered as a ranking, and the ranking hides the one difference that decides how you staff. Both credentials carry the same representation rights before the IRS, and so does a tax attorney. Most of what separates them is written in your state accountancy act, and one thing is written in Treasury's own rules of practice. Both are narrower than a credential comparison suggests. Read your open seats against the rules themselves and most of them turn out not to need the license.
CPA vs Enrolled Agent: Where the Two Credentials Are Equal
Representation before the Internal Revenue Service is where they meet, and Treasury's rules of practice say it in three consecutive paragraphs.
Section 10.3(a) lets any attorney who is not currently under suspension or disbarment practice before the Internal Revenue Service by filing a written declaration that the attorney is currently qualified and is authorized to represent the party or parties. Section 10.3(b) says the same for a certified public accountant, in the same words. Section 10.3(c) is a single sentence: any individual enrolled as an agent under the part, and not currently under suspension or disbarment, may practice before the Internal Revenue Service (eCFR, section 10.3).
Read the three together and the enrolled agent's paragraph is the shortest, because it carries no declaration step. An attorney and a CPA declare their qualification to the agency in order to practice, while an enrolled agent's authority comes from the enrollment itself. The declaration is carved back in one place for both of them, since neither has to file one before rendering written advice covered under section 10.37, and rendering that advice is still practice before the Internal Revenue Service (eCFR, section 10.3).
The IRS states the practical effect without the regulatory scaffolding. Enrolled agents, like attorneys and certified public accountants, have unlimited practice rights, which the agency defines as being unrestricted as to which taxpayers they can represent, what types of tax matters they can handle, and which IRS offices they can represent clients before (IRS, enrolled agent information).
For a bench, that settles a whole category of work. A notice, an examination, a collection matter or an appeal can sit with an enrolled agent on your staff without a licensed reviewer being the person who appears. How narrow the same rules get once a credential comes from outside the United States is a separate problem, worked through in the offshore credential guide.
How an Enrolled Agent Is Made
Enrollment is granted by the federal government, and the two routes to it produce candidates who are not interchangeable.
The Examination Route
The exam route starts with an identification number and ends with a suitability check. Under section 10.4(a), the Commissioner will grant enrollment to an applicant eighteen years of age or older who demonstrates special competence in tax matters by written examination administered by, or under the oversight of, the Internal Revenue Service, who possesses a current or otherwise valid preparer tax identification number or other prescribed identifying number, and who has not engaged in any conduct that would justify suspension or disbarment (eCFR, section 10.4).
The IRS publishes the same route as steps. Obtain a preparer tax identification number, schedule the Special Enrollment Examination, achieve passing scores on all three parts within three years, apply for enrollment and pay the fee through Pay.gov Form 23 or by mailing Form 23, Application for Enrollment to Practice Before the Internal Revenue Service, and pass a suitability check that includes tax compliance and criminal background (IRS, become an enrolled agent).
The exam changed hands in 2026, which matters if you are reading a candidate's timeline. Effective March 1, 2026, the enrolled agent Special Enrollment Examination is no longer developed and administered by Prometric, PSI Services has been selected to develop and administer it, and registration and scheduling for the 2026 test cycle are open through PSI (IRS, become an enrolled agent).
The suitability check is narrower than a background screen sounds, and the section caps what can come of it. The tax compliance check is limited to whether an applicant has filed all required individual or business tax returns and whether the applicant has failed to pay, or make proper arrangements for payment of, any federal tax debts. The suitability check is limited to whether the applicant has engaged in any conduct that would justify suspension or disbarment, including disreputable conduct as defined in section 10.51. The application will be denied only if the results of the compliance or suitability check are sufficient to establish that the practitioner engaged in conduct subject to sanctions under sections 10.51 and 10.52 (eCFR, section 10.5).
The Former Internal Revenue Service Employee Route
The second route replaces the examination with service history, and it carries a limit that never appears on a resume.
Under section 10.4(d), the Commissioner may grant enrollment to an applicant who, by virtue of past service and technical experience in the Internal Revenue Service, has qualified for it. The applicant must have had a minimum of five years continuous employment during which they were regularly engaged in applying and interpreting the Internal Revenue Code and the regulations relating to income, estate, gift, employment or excise taxes. An aggregate of 10 or more years in positions involving that work, at least three of which occurred within the five years preceding the date of application, is the equivalent of five years continuous employment, and the application must be made within three years from the date of separation from that employment (eCFR, section 10.4).
Then comes the part that decides whether the credential covers your work. Enrollment granted on former employment may be of unlimited scope, or it may be limited to permit the presentation of matters only of the particular specialty, or only before the particular unit or division of the Internal Revenue Service that the applicant's former employment qualified them for (eCFR, section 10.4). A candidate who says enrolled agent has told you their status and not their scope. Ask which route they took, and ask whether the enrollment carries a limitation.
Federal Enrollment Against a State License
The two credentials come from different governments, and that does more staffing work than it looks like it should.
The IRS is direct about the issuers. Enrolled agents are licensed by the IRS, and certified public accountants are licensed by state boards of accountancy, the District of Columbia, and US territories (IRS, understanding tax return preparer credentials and qualifications).
The federal side carries no geography. Section 10.3(c) attaches no state or jurisdiction to an enrolled agent's right to practice before the Internal Revenue Service (eCFR, section 10.3). The continuing education floor that keeps that enrollment alive is federal as well, and the hours behind it sit with the offshore training guide.
The state side is portable, but on terms, and the terms are a test rather than a formality. Washington presumes an individual whose principal place of business is not in the state to have qualifications substantially equivalent to its own, and gives that individual all the privileges of Washington licensees without obtaining a Washington license, where the individual holds a valid CPA license or certificate from a state or jurisdiction of the United States whose licensing requirements have substantial equivalency to Washington's, or, where those requirements do not, where the individual's own qualifications have substantial equivalency (RCW 18.04.350(1)(a) and (b)).
No notice, fee or other submission is required of that individual. In exchange, the individual and the firm that employs them consent to the board's personal and subject matter jurisdiction and disciplinary authority, to comply with the chapter and the board's rules, to cease offering or rendering professional services in the state, individually and on behalf of a firm, if the license from the state of the individual's principal place of business is no longer valid, and to the appointment of the issuing state board as their agent for service of process (RCW 18.04.350(2) and (3)). The third of those is the one a bench plan turns on, because the privilege ends when the home license does.
That is one state's enacted version, so the mobility test that binds a seat is whichever one your own board wrote. The out-of-state signing question is answered separately in the CPA job description.
The Report Line Is the One the Enrolled Agent Credential Cannot Cross
Representation rights are equal, and the two credential routes are just different machinery. The report is neither of those, and it is the only place where the letters decide the work rather than describe it.
The reservation lands on the firm and on the report, not on tax skill, and an enrollment does not reach it. Washington reserves two categories of work at once, and a firm has to clear two conditions to touch either one. No firm with an office in the state may perform or offer attest or compilation services unless the firm is licensed under RCW 18.04.195 and all of its offices in the state are maintained and registered under RCW 18.04.205 (RCW 18.04.345(3)(a)).
Attest, in that act, is a closed list of four named services. It covers any audit or other engagement performed under the statements on auditing standards, any review of a financial statement performed under the statements on standards for accounting and review services, any engagement performed under the statements on standards for attestation engagements, and any engagement performed under the Public Company Accounting Oversight Board auditing standards. A compilation is defined separately, as presenting information that is the representation of management in the form of financial statements without undertaking to express any assurance on them (RCW 18.04.025).
The model act the AICPA and NASBA publish together enumerates attest as five services rather than four, splitting the attestation standards into examinations of prospective financial information and everything else performed under those standards (Uniform Accountancy Act, Section 3(b)). That version sits in the growth discussion.
The act's word on the enrolled agent title is to leave it to the United States Department of the Treasury. Nothing in the chapter prohibits a person from using that title, licensed or not, where Treasury has authorized the use at the time (RCW 18.04.345(2)(b)). The title rule sits with the individual report signature rule, the carve-out for unlicensed employees of a licensed firm, and the list of services left open to non-licensees, all worked through line by line in the CPA job description.
Practice privileges do not create attest capacity on their own. An individual who qualifies for practice privileges and performs any attest service described in RCW 18.04.025(1) may only do so through a firm that has obtained a license under RCW 18.04.195 and RCW 18.04.215, or that meets the requirements for an exception from the firm licensure requirement (RCW 18.04.350(4)).
For a staffing plan the consequence runs both ways. Adding enrolled agents never adds attest or compilation capacity, however senior they are, because the constraint is the firm license and a licensee's signature rather than tax competence. Adding a CPA to a preparation bench does not add that capacity either, because the firm license and an actual engagement have to be there first. Which of the three service levels a client actually needs, and what independence each one demands, is worked through separately.
Which of Your Open Seats Needs the License
Take the open roles one at a time, because each answers to a different rule.
Preparation and workpaper build answer to a federal identification duty rather than to a credential. The question is whether the work amounts to preparing a return, not what letters the preparer holds, and that requirement is answered in the onboarding guide. Nothing in the accountancy act's open list reserves return preparation to a licensee, so this is a competence hire.
Notices, examinations, collections and appeals are the seat where an enrolled agent is the equal of a licensee, on the regulation's own terms. If the thing drowning the partner is IRS correspondence, the constraint is hours rather than authority, and a licensed hire buys authority the firm already has. What the enrolled agent may say about the designation while doing that work is regulated in its own right, and the advertising rule sits with the client acquisition guide.
The report seat is the reserved one, and it is short. In Washington, anything that ends in a report going out over a person's name needs both the individual license and the firm license behind it, and your own act is where to confirm that pairing before you write the job description. That is the seat to fill first if attest work is growing, and it is the only seat in the firm where this comparison has one right answer.
The reviewer seat can go wrong in both directions. Reserving it for a licensee is one error when the work under review is return preparation, where review is a competence and a process question rather than a licensing one, and where the due diligence standard that governs relying on someone else's work product reaches any practitioner, whichever credential they hold. The quality control guide reads that standard in full. Leaving it with whoever is most senior is the other error, and it fails the moment the reviewed work ends in an attest or compilation report and the reviewer's license stops being optional.
An Enrolled Agent Bench Under a Licensed Reviewer Is a Structure, Not a Compromise
Put the seats together and a shape falls out. Enrolled agents carry preparation, notices and representation. A licensed partner or reviewer carries anything that ends in a report, the firm license, and the final judgment on the file. None of that is a workaround, because each seat is filled by the credential the rule actually asks for.
The objection worth taking seriously is the client-facing one. A firm that has always said CPA on every engagement letter may worry that an enrolled agent on the file reads as a step down. The IRS calls enrolled agent status the highest credential it awards (IRS, enrolled agents), and the rules on how that designation may be described are specific enough that a firm can say it accurately without overclaiming.
The harder objection points the other way. A credential of either kind tells you what somebody was tested on, and it tells you nothing about whether this season's returns come back clean. That is a review question, and it is worth answering before the org chart.
Questions Firms Ask
What Can a CPA Do That an Enrolled Agent Cannot?
Issue a report. In practice that means an audit, a review or a compilation going out over the firm's name, with the firm license standing behind it. On representation before the IRS, on preparation and on tax advice, the answer is nothing, which is what the practice rules say in consecutive paragraphs.
How Do You Check That an Enrolled Agent Is Actually Enrolled?
Not with the public directory, even though one exists. The IRS Directory of Federal Tax Return Preparers with Credentials and Select Qualifications does list enrolled agents, but only those who also hold an active preparer tax identification number, it is updated weekly and may take up to four weeks to show new or revised information, and a preparer can opt out of appearing in it (IRS, FAQs on the preparer directory). An absence from it settles nothing about a candidate.
For the enrollment itself the IRS asks you to submit a request through its Contact the Office of Enrollment form, selecting the option for requesting information about an enrolled agent, and it states that the policy of the Office of Enrollment is to answer inquiries within 72 hours, while warning that unanticipated operational demands may delay a response (IRS, verify the status of an enrolled agent). A CPA license runs the other way, since state boards publish lookups. Put the check in your hiring step rather than the week before a deadline.
Start From the Seat, Not From the Letters
Write out the seats you are trying to fill, then mark every one that ends in a report going out over somebody's name. Those are the ones your accountancy act decides for you, and in Washington they need the individual license and the firm license behind them. Everything else is a competence decision, and treating it as a credential decision is how a small practice ends up paying licensed rates for unlicensed work.
If the reason a job posting says CPA is capacity rather than a reserved duty, what the firm needs is a bench and a review chain, not a license. Accountably places trained offshore accountants and tax preparers inside US firms, with 30+ placements across 20+ firms since 2022, ramped on your own software and procedures in about 3 to 4 weeks. The signature, the opinion and the final judgment stay with your firm.
