How Hard Is the Enrolled Agent Exam? Parts, Pass Mark and Study Time
The IRS does not rate the enrolled agent exam's difficulty or publish pass rates, so this guide sticks to what it does publish about the format and law, and to how our own study plan is built. Source: IRS "Enrolled agents: Frequently asked questions" (page updated 26 Oct 2026), checked 28 Oct 2026.
What makes the SEE hard
- Breadth. Each part covers a whole content outline: 6 domains on Part 1, 3 on Part 2 and 4 on Part 3, with no option to skip one.
- Pace. 100 questions in 3 hours 30 min, about 2.1 minutes each, in three sections that lock once you confirm them.
- Closed book. No notes or references; paper, pencil and a calculator are provided at the test center.
- Current-year law. The 2026-27 window tests law as amended through 31 Dec 2025, including the One Big Beautiful Bill Act changes for 2025.
- Scaled scoring. You need 500 on a 200-800 scale. The IRS does not say how many correct answers that takes, and 15 unscored items are mixed in.
Which part is hardest?
The IRS does not say: it publishes no pass rate for any part (what it does publish). What differs is the work each part asks for:
| Part | Domains | Largest domain (scored questions of 85) | What makes it demanding |
|---|---|---|---|
| Part 1: Individuals | 6 | Income and Assets (17) | The most arithmetic and the most 2025 figures to learn |
| Part 2: Businesses | 3 | Business Tax Preparation (37) | Entity rules and basis calculations, the largest single domain on the SEE |
| Part 3: Representation | 4 | Practices and Procedures (26) | Circular 230 section numbers, deadlines and longer question stems |
Try a free question from each part to feel the difference: a Part 1 HSA question, a Part 2 C corporation question and a Part 3 Circular 230 question.
How long to study for the EA exam
The IRS gives no study-hours figure. Our free study plan schedules one topic a weekday and then a week of full practice exams: 4 weeks for Part 1, 4 for Part 2 and 3 for Part 3, for someone who already prepares returns. Add time for any topic that is new to you; how to pass stretches it to six weeks a part with extra review.
The 2026-27 testing window is open from 1 Jul 2026 to 28 Feb 2027 for U.S. candidates. Testing pauses after 28 Feb 2027 while the exam is updated; the 2027-28 window is not announced yet. The window planner shows when to sit each part and still keep time for a retake.
How to tell if you are ready
- Read the free study notes for your weakest domain, such as Circular 230 duties.
- Sit full 100-question practice exams under the real time limit.
- Book when you score comfortably above our 70% benchmark on questions you have not seen. That benchmark is ours, not the IRS's.
