REG Cheat Sheet 2026: One-Page Review of Must-Know Facts

Exam Format at a Glance

Before memorizing tax rules, memorize the mechanics of the appointment itself. The Uniform CPA Examination: Taxation and Regulation (REG) section is developed and scored by the AICPA Board of Examiners, with NASBA and individual state boards handling candidate eligibility and administration, and Prometric delivering the computer-based test at approved centers.

Under the blueprint effective January 1, 2026, a REG appointment runs four hours and is broken into five testlets:

• Two multiple-choice testlets containing the exam's 72 MCQs total
• Three task-based simulation testlets containing the exam's 8 TBSs total

MCQs and TBSs are weighted equally - each contributes 50% of your total score, so a candidate who is strong on conceptual multiple-choice items but weak on multi-step simulations (or vice versa) is only ever getting half the picture right. If you want a deeper breakdown of how testlets are sequenced and timed, the REG Study Guide 2026 walks through pacing strategy in more detail.

The Five REG Domains, Ranked by Weight

REG content is organized into five domains. Understanding their relative weight tells you where your study hours should go. For the full content breakdown of each area, see the REG Exam Domains 2026 guide.

Registration and Fees Snapshot

REG is a section of the CPA Exam, not a standalone credential you renew separately - it's one piece of the broader licensure path. Because eligibility, credit windows, and CPE requirements are set jurisdiction-by-jurisdiction, always confirm specifics with your own state board before scheduling. A general overview of who qualifies is available in the REG Requirements 2026 article.

• Candidates need board approval and a Notice to Schedule (NTS) before booking a Prometric appointment.
• In NASBA CPA Examination Services jurisdictions, the exam-section fee is $268.59.
• Application or board fees are set separately by each jurisdiction and are not included in the section fee.

For a full cost breakdown across the different fee categories, check the REG Certification Cost 2026 guide before you register.

Scoring Rules to Get Right

A surprising number of candidates misunderstand REG scoring, which creates unnecessary anxiety. Get these facts straight:

• A passing score is 75 on a 0-99 scale - this is not the same as answering 75% of questions correctly.
• Scores are not curved against other candidates in your testing window.
• Both scored components (MCQ and TBS) contribute equally, so there's no way to "coast" through simulations on MCQ strength alone.

For the mechanics behind how raw performance converts to that 0-99 scale, see the dedicated REG Passing Score 2026 breakdown. And if you want to know how your effort compares to the broader candidate pool, the REG Pass Rate 2026 article covers the cumulative Q1-Q2 2026 pass rate of 66.78%.

What Changes for 2026

Content stays current with recent law, and 2026 candidates should be aware of one specific update: provisions of H.R. 1 with 2024 or 2025 effective dates became eligible for REG testing starting July 1, 2026. If your testing window falls before or after that date, confirm which version of the content you're being held to so you're not studying material that isn't yet - or is no longer - in scope.

Outside of that update, the underlying domain weights and exam structure described above are what's "new" relative to prior blueprints, so make sure any older study materials you're using reflect the current five-domain, 72-MCQ, 8-TBS structure rather than an outdated format.

High-Yield Topics by Domain

Because REG blends tax law with procedural and legal content, high-yield preparation means mastering recurring patterns rather than isolated facts. A few areas worth extra repetition:

• Entity comparisons (Domain 5): Be able to explain, side by side, how the same transaction is taxed differently across entity types - this comparative reasoning shows up constantly in both MCQs and TBSs.
• Individual income mechanics (Domain 4): Practice tracing an item from gross income through adjustments, deductions, and credits - simulations often test the full flow, not just one step.
• Property transaction basis rules (Domain 3): Even though this domain carries the smallest weight, basis concepts resurface inside entity and individual questions, so weak fundamentals here cost points elsewhere too.
• Procedural authority (Domain 1): Know practitioner responsibilities and IRS procedure well enough to answer quickly - these questions reward recognition speed over deep calculation.
• Business law fact patterns (Domain 2): Focus on applying rules to scenarios rather than reciting definitions, since REG tests application over recall.

If you're still building a mental map of how these topics connect across domains, the REG Exam Domains 2026 guide is the natural next stop, and How Hard Is the REG Exam? is useful context for calibrating how much time each area deserves.

One-Week-Per-Domain Study Map

A simple, REG-specific way to sequence review in the weeks before your appointment is to dedicate blocks of time proportional to domain weight, saving the largest domains for the middle of your schedule when your knowledge base is deepest.

Run your final practice sessions on a full-length REG practice test so the four-hour pacing and testlet transitions feel familiar before test day. Repeating this on the practice test platform a second time closer to your appointment helps confirm which domains still need attention.

Test-Day Mechanics

Know the logistics cold so nothing about the appointment itself surprises you:

• You'll need board approval and a valid Notice to Schedule before booking with Prometric.
• The exam provides built-in spreadsheet and four-function calculator tools - practice using them rather than a physical calculator so the interface feels familiar.
• The 15-minute break after Testlet 3 is stopped-clock, meaning it doesn't eat into your four hours.
• Confirm your specific testing window and any registration deadlines through the REG Exam Dates 2026 guide, since scheduling windows and deadlines are set at the jurisdiction level.
