How to Pass the EA Part 1 Exam: Individual Income Tax Study Guide

The IRS Special Enrollment Examination (SEE) Part 1 covers individual income tax. Passing it earns you the right to sit for Parts 2 and 3 and ultimately become an Enrolled Agent — one of only three types of practitioners authorized to represent taxpayers before the IRS in all matters.

Part 1 has 100 questions and a 3.5-hour time limit. The passing score is 105 out of 130 scaled points. Questions are multiple-choice and scenario-based, so rote memorization alone won't cut it — you need to apply rules to fact patterns.

What's Actually Tested

Prometric publishes a content specification outline. The major domains and their approximate weights are:

• Preliminary work and taxpayer data (~17%) — filing status, dependency tests, recordkeeping
• Income (~21%) — wages, interest, dividends, business income, rental income, capital gains, retirement distributions
• Adjustments to income (~11%) — student loan interest, educator expenses, alimony (pre-2019 divorces), SE deductions
• Deductions (~18%) — standard vs. itemized, SALT, mortgage interest, charitable contributions
• Credits (~14%) — CTC, EITC, education credits, child and dependent care credit
• Other taxes (~9%) — SE tax, AMT, net investment income tax
• Payments (~10%) — withholding, estimated taxes, refundable credits

Where to Spend Your Study Time

A common mistake is spreading effort evenly across all topics. Instead, weight your time to match the exam's weight.

Highest-yield areas:

Income (21%) is the single largest domain. Focus on the difference between ordinary income and capital gains, the taxation of Social Security benefits (the provisional income formula), the rules for rental income, and when bartering income is recognized.

Deductions (18%) requires knowing every post-TCJA change cold: the $10,000 SALT cap, the $750,000 mortgage interest limit, and the elimination of most miscellaneous itemized deductions. The standard deduction amounts for each filing status come up repeatedly.

Filing status and credits together (~31%) are heavily scenario-tested. Expect questions where a taxpayer qualifies for more than one status and you must choose the most beneficial one. For credits, know the refundable versus nonrefundable distinction — it changes the answer on many questions.

The Three Most Common Exam Traps

Trap 1: Confusing Qualifying Child and Qualifying Relative

These two definitions share some rules but differ on the gross income test, the support test, and the age requirement. Qualifying child has no gross income limit; qualifying relative does ($5,050 for 2024). Many questions hinge on this difference.

Trap 2: Getting SE Tax Wrong

Self-employment tax is 15.3% on 92.35% of net SE income — not 15.3% of the full amount. The deduction for half of SE tax is an above-the-line adjustment, not a business expense on Schedule C. Mixing these up kills easy points.

Trap 3: Applying Pre-TCJA Rules

The Tax Cuts and Jobs Act of 2017 eliminated personal and dependent exemptions, suspended many itemized deductions, and capped SALT. Exam questions are written to test whether you know the current law. Watch for answer choices that include an exemption amount — those are traps.

A Practical Study Framework

Weeks 1–2: Build your foundation on filing status, gross income inclusions and exclusions, and adjustments to income. These topics appear on nearly every question set.

Weeks 3–4: Work through deductions, credits, and capital gains. Do practice questions after each topic — don't wait until the end.

Week 5: Cover SE tax, AMT, passive activity rules, and retirement accounts. These are more mechanical and respond well to formula drilling.

Week 6: Timed practice exams. Aim for at least 3 full 100-question sessions. Analyze every wrong answer, not just the score.

Using Practice Questions Effectively

The IRS exam draws heavily on fact patterns, not definition recall. When you get a question wrong, identify whether the error was:

1. A missing rule (you didn't know the law)
2. A misread fact (you knew the rule but applied it to the wrong person)
3. A threshold error (you knew the rule but had the wrong dollar amount)

Each type requires a different fix. Rule gaps need re-reading the material. Fact errors need slower, more careful reading habits. Threshold errors need a focused pass through the key numbers — AGI phase-out ranges, contribution limits, and penalty thresholds.
