The Enrolled Agent (EA) is the highest credential the IRS awards, and the Special Enrollment Examination (SEE) that earns it is a test of applied tax knowledge, not memorised trivia. The questions hand you a taxpayer’s facts and ask for the correct treatment, so the goal of studying is to understand how individual and business tax actually works, and how a practitioner represents a taxpayer ethically, well enough to reason to the right answer under the current year’s rules. This guide is a full, self-study course: it walks through the three SEE parts in depth, explains the tax and ethics concepts the questions are built on, and turns all of it into a part-by-part plan. It is original teaching material and study guidance only. It contains no real or simulated exam questions. Because tax law changes every year, you must study current-year material and confirm the rules against the IRS’s own enrolled-agent resources before you sit.
Chapter 1: Exam overview and how to use this guide
What the EA credential actually is
An Enrolled Agent is a federally authorised tax practitioner, empowered by the US Department of the Treasury, with unlimited rights to represent taxpayers before the IRS: any taxpayer, any tax matter, any IRS office. That is the same representation right a CPA or attorney has, but earned through demonstrated tax expertise rather than a broad accounting licence or a law degree. Two features make the EA distinctive. First, there is no education requirement, no degree and no 150 credit hours, which makes it one of the most accessible serious credentials in US finance. Second, it is a federal credential, recognised in every state, unlike the state-by-state CPA licence. The trade-off is scope: the EA is a tax specialism, not a general accounting qualification, so it does not let you perform audits or sign attest reports.
The shape of the exam
Most people earn the EA by passing the three-part Special Enrollment Examination (SEE): Part 1 Individuals, Part 2 Businesses, and Part 3 Representation, Practices and Procedures. Each part is 100 multiple-choice questions (of which 85 are scored and 15 are unscored experimental questions) in 3.5 hours, with about four hours of total seat time once a tutorial, a survey, and breaks are included. Each part is scored on a scale of 200 to 800, and a scaled score of 500 is needed to pass. The three parts are independent and can be taken in any order, and passing scores carry over for up to three years, so you do not have to pass them all at once. The IRS does not publish official pass rates, so treat any percentage you see online as an unofficial estimate.
How to use this course
Read the three part chapters (2 to 4) in the order you intend to sit them, then read Chapters 5 and 6 on enrollment and the timeline before you book, because the PTIN step and the carryover window shape your schedule. Treat the bold concepts as a checklist: by the end of each part chapter you should be able to explain how that area of tax works and how it would appear in a question. The last two chapters turn the content into a schedule and a description of exam day and the path to enrollment. Worked illustrations appear where a concept is easy to misread, but none of these are exam questions. They are teaching examples that show how the rule behaves. Above all, remember the currency rule: tax law changes annually, so anchor everything to the current year.
Chapter 2: Part 1 - Individuals
Part 1 covers the taxation of individuals, and for most candidates, especially anyone who has prepared individual returns, it is the most familiar ground, which is why it is a common and confidence-building first part. It maps onto the structure of an individual tax return, so studying it is partly a matter of understanding how that return is built up line by line.
What Part 1 covers
The area runs through the whole individual return: filing status (single, married filing jointly, married filing separately, head of household, and qualifying surviving spouse) and how it is determined; dependents and the tests for claiming them; gross income and what is and is not taxable; adjustments to income; deductions, both the standard deduction and itemised deductions; and credits, which reduce tax directly. It also covers basis, gains, and losses on the sale of property, and specialised individual topics such as the basics of retirement accounts and estate and gift considerations. The organising idea is the flow from total income down to taxable income and then to the tax and any credits.
The flow of an individual return
The most useful mental model for Part 1 is the sequence the return itself follows. You begin with total (gross) income from all taxable sources: wages, interest, dividends, business and rental income, capital gains, and retirement distributions, among others. From that you subtract adjustments to reach a key subtotal that several other calculations key off. You then subtract either the standard deduction or itemised deductions, whichever is larger, to arrive at taxable income, the figure the tax is actually computed on. Finally you apply the tax, then reduce it by any credits and account for payments already made through withholding or estimated taxes, arriving at a refund or a balance due. Understanding this top-to-bottom flow turns a mass of separate rules into one coherent structure, and it makes clear why a given item matters: an exclusion keeps income out at the top, a deduction reduces the middle, and a credit cuts the tax near the bottom.
Why it matters and a worked idea
This part is the foundation of individual tax practice, and several of its concepts recur in Part 2 when individuals own businesses. The distinction the exam leans on hardest is between a deduction and a credit: a deduction reduces the income that is taxed, so its value depends on the taxpayer’s tax rate, whereas a credit reduces the tax itself dollar for dollar. As a teaching example of why that matters: a credit and a deduction of the same stated amount are not equally valuable, because the deduction only saves the tax on that amount while the credit removes that amount of tax outright, and a question may turn on knowing which mechanism applies and therefore which gives the larger benefit. A second distinction worth holding is between refundable and non-refundable credits: a non-refundable credit can reduce tax only to zero, while a refundable credit can produce a refund beyond the tax owed, so two credits of equal size can differ in value for a low-tax taxpayer. Study Part 1 by following a return’s logic rather than memorising isolated rules, and keep the figures current, because thresholds and amounts are adjusted year to year.
Chapter 3: Part 2 - Businesses
Part 2 covers the taxation of businesses and is widely regarded as the hardest of the three parts, because it spans many entity types and the rules differ for each. Give it the most study time. The reward for the effort is that business tax is where much of the EA’s professional value lies, since business returns are more complex and the representation work more substantial.
What Part 2 covers
The area works through the main ways a business can be organised and how each is taxed: sole proprietorships (reported on the individual’s return), partnerships (which generally pass income through to partners rather than paying tax themselves), corporations including S corporations (where the C corporation is taxed at the entity level and the S corporation generally passes income through), and trusts, estates, and tax-exempt organisations. Cutting across the entity types are the mechanics common to all businesses: business income and expenses, the treatment of assets including depreciation, and payroll taxes and the employer’s obligations. The skill being tested is recognising the entity in the facts and applying the right set of rules.
Basis and distributions across entities
A theme that ties the entity types together, and that the exam returns to often, is the interaction of basis and distributions. In a pass-through entity, an owner’s basis in their interest starts with what they contributed, rises as the entity earns income that is taxed to them, and falls as they take distributions or are allocated losses. Basis matters because it generally limits the losses an owner can deduct and determines whether a distribution is a tax-free return of capital or a taxable event. As a teaching example of this machinery: when a partnership allocates taxable income to a partner, that partner’s basis increases even if no cash is distributed, so a later cash distribution can be a tax-free return of that already-taxed income rather than new taxable income, and a question that tracks contributions, allocated income, and distributions is testing whether you can follow basis through those steps. The C corporation behaves differently, keeping its own earnings and taxing shareholders separately when it distributes them, which is why the pass-through versus entity-level split is the master distinction of the part.
Why it matters and a worked idea
The breadth is exactly why Part 2 is hard: a fact pattern that looks similar can have very different tax consequences depending on the entity. The most important structural distinction is between pass-through taxation and entity-level taxation. As a teaching example: the same business profit is taxed once in the owners’ hands if the business is a partnership or S corporation, but a C corporation pays tax on its profit and the shareholders may then be taxed again on distributions, the classic double-taxation pattern, so identifying the entity type is the first move in answering almost any Part 2 question. Payroll adds a further layer that applies regardless of entity: an employer must withhold and deposit employment taxes and meet reporting obligations, and the rules here are about compliance and timing rather than the income tax itself, so treat payroll as its own block. Study this part one entity type at a time, making sure you can state for each how income is taxed, who pays, and how basis and distributions work, and budget extra weeks here because the volume genuinely is larger.
Chapter 4: Part 3 - Representation, Practices and Procedures
Part 3 covers practice before the IRS itself: the ethics, the authority, and the procedures a practitioner uses to represent a taxpayer. It is the narrowest part in scope and a sensible one to finish on, but it is far from trivial, because it defines the professional responsibilities that come with the EA’s representation rights.
What Part 3 covers
The backbone of this part is Circular 230, the Treasury Department’s rules governing who may practise before the IRS and how they must behave. It sets out the duties a practitioner owes, the standards for diligence and competence, conflict-of-interest rules, and the sanctions for breaching them, which range from censure through suspension to disbarment from practice. Around that core, the part covers powers of attorney and how a representative is authorised to act for a taxpayer, the conduct of examinations (audits), the appeals process for disputing a result, and collection procedures. It also covers building a taxpayer’s case and the recordkeeping that supports it. The unifying theme is the proper, ethical exercise of the representation authority the EA grants.
The examination, appeals, and collection sequence
A large share of Part 3 is the lifecycle of a dispute, and understanding its order makes the procedural questions much easier. It typically begins with an examination (an audit), where the IRS reviews a return and may propose changes. If the taxpayer disagrees, they can take the matter to Appeals, an independent function within the IRS whose role is to resolve disputes without litigation, and beyond that the courts remain an option. Separately, once tax is assessed and unpaid, the collection process begins, with its own procedures, notices, and taxpayer options such as installment agreements or offers in compromise. An EA can represent the taxpayer at each of these stages, which is exactly why the part covers them. As a teaching example of why the sequence matters: a taxpayer who disagrees with an examiner’s proposed adjustment generally pursues Appeals rather than jumping to collection options, because collection concerns an amount already assessed, and a question that asks for the appropriate next step is testing whether you know where in the lifecycle the taxpayer currently sits.
Why it matters and a worked idea
This part is where the EA’s defining privilege, representation, is paired with its defining responsibility. The exam tests whether you know not just the procedures but the ethical line a practitioner must hold. As a teaching example of the reasoning rewarded: if a client asks an EA to take a position the practitioner knows lacks a reasonable basis, Circular 230’s standards point toward declining to do so rather than accommodating the client, because the duty to the tax system constrains what the practitioner may sign, and questions are written to test whether you understand that the rules of practice override client pressure. Study Part 3 by understanding the purpose behind each rule and procedure, since that understanding lets you reason through scenarios that a memorised list cannot cover.
Chapter 5: The PTIN, enrollment, and keeping the credential
The exam is the centre of the EA path, but it is bracketed by administrative steps that matter just as much, because missing them can stall you before you start or after you finish.
Before the exam: the PTIN
Before you can schedule any part of the SEE, you need a PTIN (Preparer Tax Identification Number) from the IRS, which is the identifier required of anyone who prepares federal tax returns for compensation. Getting it first removes a scheduling delay later, so treat it as step zero. The SEE itself is delivered for the IRS by PSI Services, which took over administration effective March 1, 2026; you register and schedule through PSI, while the IRS sets the content and the requirements.
After passing: enrollment
Passing all three parts qualifies you to apply for enrollment, but it does not by itself make you an EA. You apply on Form 23, and you must pass an IRS background and tax-compliance check, which confirms, among other things, that your own tax filings are in order. Do this within the three-year carryover window so no passing score expires before you complete enrollment. Only once enrollment is granted may you practise as an EA.
Keeping it active
The credential is maintained, not permanent. Enrolled Agents renew enrollment every three years on Form 8554, on a schedule tied to the last digit of their Social Security number, and must complete 72 hours of continuing education per three-year cycle, including 6 hours of ethics, with a minimum of 16 hours each year (2 of them ethics). Planning continuing education into your routine from the start, rather than scrambling near a deadline, keeps renewal painless and your knowledge current, which matters in a field where the law changes every year.
Chapter 6: Study plan, timeline, and exam day
With the content and the administrative steps understood, the remaining work is pacing the three parts. Two facts drive the plan: the parts are independent and can be taken in any order, and passing scores carry over for up to three years, so you can study one part, sit it, and move on rather than learning all three at once.
Budget the hours and choose an order
Plan for roughly 120 to 200 hours across all three parts, typically over six to twelve months alongside work. A common and sensible order is Part 1 (Individuals) first, because it is the most familiar; Part 2 (Businesses) in the middle with extra time, because it is the broadest and hardest; and Part 3 (Representation) last, because it is the narrowest in scope. In weeks, Part 1 suits about four to six weeks at eight to ten hours a week, Part 2 deserves six to eight weeks, and Part 3 can often be done in three to four. You may take the parts in any order, but this sequence builds momentum and front-loads the hardest material when your study energy is highest. To turn this into dated weeks for your own start date, use the free study-plan generator. If you are still deciding between a tax specialism and a broader accounting licence, the EA vs CPA comparison covers scope, entry requirements, and cost.
Practise with current-year questions
Reserve the final week or two of each part for timed practice questions, including the IRS’s own free sample questions, which give you the official style. The currency rule matters more here than on almost any other exam: tax law changes annually, so study current-year material and treat older practice sets with caution, because a question testing a superseded figure or rule will quietly teach you the wrong answer. Each time you miss a question, trace it back to the underlying rule and fix the understanding, not just the answer.
Exam day and format
On the day, each part is a 3.5-hour computer-based exam of 100 multiple-choice questions, taken at a PSI test centre or via online proctoring, with about four hours of seat time to allow for the tutorial, a survey, and two scheduled breaks. Because the exam moved to PSI in 2026, the window changed: the 2026 cycle runs from 1 July 2026 to the end of February 2027 for domestic candidates, scheduling opens on 1 May 2026, and there is no testing during the March to June 2026 transition. Window dates can shift year to year, so confirm the current window with the IRS and PSI before you plan. You may take each part up to four times per testing window. The pacing works out to roughly two minutes per question, so practise full sets under time, flag and return to hard items rather than stalling, and keep moving. Apply the disciplined reading you practised: identify the taxpayer’s facts, determine the correct treatment under the current rules, and choose the answer that follows. Having prepared at full length with current-year material and confirmed the rules against the IRS’s own resources, the format will feel familiar rather than overwhelming, which is exactly the advantage the preparation was meant to buy.
