Tax law does not forgive the unprepared, and this unofficial study guide exists so you never walk into the examination room guessing.

But what sits inside these pages? Four areas. Fourteen subtopics. Hundreds of worked mechanics. Individual income, equity compensation, alternative minimum tax, foreign earned income, passive losses, gift taxation, entity compliance, international sourcing, controlled foreign corporations, partnership basis, fiduciary rules, entity liquidation, depreciation recapture, installment sales, and related-party traps. Each section opens with a scenario. Then the rule. Then the math. Then the mistake most candidates make. Short chapters. Sharp examples. No filler. You will not find vague summaries here. You will find dates, dollar figures, basis schedules, and the exact ordering rules that separate a passing answer from a failing one. And yes, the hard corners are included. The ones other guides skip. The ones that appear on exam day and make strong candidates freeze.

And here is what makes this edition different. It reflects the 2026 syllabus. The One Big Beautiful Bill changes. The revised foreign earned income exclusion. The permanent fifteen-million-dollar transfer tax exemption. The rebranded NCTI regime replacing old GILTI mechanics. The updated AMT phaseout thresholds. The new SALT ceiling. Most competing guides still teach 2024 numbers dressed in fresh covers. This one does not. Every rate, every limit, every indexed figure has been rebuilt for the current testing window. So you study what will actually appear, not what appeared two cycles ago.
