Prepare for the IRS Enrolled Agent credential — all three parts of the Special Enrollment Examination (SEE) — with a focused study companion built for the current testing window. Enrolled Agent Study Guide organizes everything into six sections that follow the official exam specifications part by part, so you drill the rules an exam question actually hangs on instead of wandering a topic list. BUILT FOR THE CURRENT EXAM Written for the July 2026 – February 2027 testing window: tax law as amended through December 31, 2025, including the 2025 law changes the exam now tests — the new senior deduction, the tips and overtime deductions, the higher SALT cap, current retirement limits, and the restored 100% bonus depreciation. Exam logistics reflect the current PSI testing experience, scoring scale, and carryover rules. FIVE WAYS TO STUDY • 160+ flashcards — tap to flip, tagged by exam section • 120+ multiple-choice questions with worked explanations • 90+ true/false drills built from real tax-preparer misconceptions • Term-matching game — pair the key terms, in quick rounds of five • Searchable reference: a 110+ term tax glossary plus 40+ key rules, formulas, penalty rates, and figures SIX EXAM SECTIONS, ALL THREE PARTS 1. Part 1: Preliminary Work & Income — filing requirements and status, dependents, income and assets, retirement income, capital gains and basis, adjustments 2. Part 1: Deductions, Credits & Taxation — itemized deductions, QBI, the major credits, AMT, self-employment tax, advising individuals, estate and gift returns 3. Part 2: Business Entities — sole proprietorships, partnerships, C corporations, S corporations, formation, basis, elections 4. Part 2: Business Tax Preparation — business income and deductions, depreciation and Section 179, employment taxes, trusts, exempt organizations, farmers, rentals 5. Part 3: Practices & Procedures — Circular 230 duties, sanctions, preparer penalties, e-file rules, continuing education and renewal 6. Part 3: Representation before the IRS — powers of attorney, collections, installment agreements and offers in compromise, audits, appeals BUILT FOR HOW YOU ACTUALLY STUDY • Every practice item explains WHY the answer is right — the explanation is the lesson • Works completely offline • Clean, fast, distraction-free — no ads, ever • Track nothing, sign into nothing: no account required FREE TO START The free version previews every study mode; any purchase below unlocks the complete library — all four options unlock identical content.
