What Does REG Actually Mean?
REG is short for the Uniform CPA Examination: Taxation and Regulation - one of the four sections a candidate must pass to become a licensed CPA in the United States. It is not a standalone certification you renew each year; it is an exam section that certifies a specific body of knowledge at a single point in time. Once you pass REG, that result becomes part of your overall CPA Exam record, which state boards use alongside education and experience requirements to grant licensure.
Because "REG" is used by multiple unrelated credentials across different industries, it's worth being precise here: on this site, and in this article, REG means only the AICPA's Taxation and Regulation section of the Uniform CPA Examination. If you're trying to understand what REG stands for in a broader sense, our companion piece on What Does REG Stand For? walks through the naming and disambiguation in more depth.
Who Administers REG and Why That Matters
Three organizations share responsibility for getting you from "signed up" to "scored," and understanding the division of labor helps you know where to direct questions:
- AICPA Board of Examiners - develops the exam content and blueprint, and scores completed exams.
- NASBA and individual state boards - manage candidate administration and eligibility determinations, since licensure requirements are set at the state level.
- Prometric - delivers the computer-based exam at test centers.
This structure explains why two candidates can have very different registration experiences even though they're taking the identical exam content. Your state board decides whether you're eligible to sit, issues your Notice to Schedule, and eventually licenses you; AICPA decides what's on the test and what score you earned; Prometric just runs the appointment. For a full walkthrough of eligibility mechanics, see REG Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Breaking Down the Five REG Domains
Under the blueprint effective January 1, 2026, REG content is organized into five domains, each weighted differently on the exam. Knowing the weights helps you allocate study time proportionally rather than treating every topic equally.
Domain 1: Ethics, Professional Responsibilities and Federal Tax Procedures (10-20%)
Covers practitioner conduct rules, Circular 230-type responsibilities, and federal tax administration/procedure.
- Understand practitioner duties to clients and to tax authorities
- Know the procedural steps in tax return preparation and representation
Domain 2: Business Law (15-25%)
Covers contracts, agency, business structures, and other legal frameworks that intersect with tax and accounting practice.
- Contract formation, performance, and breach concepts
- Agency relationships and business entity legal characteristics
Domain 3: Federal Taxation of Property Transactions (5-15%)
Covers basis, gains and losses, and characterization of property dispositions.
- Basis computation and adjustments
- Classification of gains/losses (ordinary vs. capital)
Domain 4: Federal Taxation of Individuals (22-32%)
Covers individual income tax computation, filing status, deductions, and credits at a conceptual level.
- Gross income inclusions and exclusions
- Deduction and credit eligibility rules
Domain 5: Federal Taxation of Entities (including tax preparation) (23-33%)
The largest content area on the exam, covering corporations, partnerships, and other entity tax treatment plus preparation mechanics.
- Entity formation, distributions, and liquidation tax treatment
- Partnership and corporate return preparation concepts
Notice that Domains 4 and 5 together can account for nearly two-thirds of the exam. If you're building a study calendar, that combined weight should drive how many hours you assign each week. For a domain-by-domain breakdown with more granular subtopics, see REG Exam Domains 2026: Complete Guide to All 5 Content Areas.
Key Takeaway
Prioritize Federal Taxation of Entities and Federal Taxation of Individuals first - together they can represent up to 65% of your score, more than Ethics, Business Law, and Property Transactions combined.
How REG Questions Are Structured
REG is delivered across five testlets in a single four-hour appointment. The exam contains 72 multiple-choice questions and 8 task-based simulations (TBSs) in total, and - importantly - MCQs and TBSs each contribute 50% of your overall score. That 50/50 split means a candidate can't coast through simulations by relying on multiple-choice strength alone; both formats carry equal weight.
MCQs test discrete knowledge and application quickly, while TBSs present realistic scenarios - often involving research, calculation, or document review - that require you to apply multiple rules in sequence. The exam provides on-screen tools including a spreadsheet and a four-function calculator to support these tasks.
One structural detail candidates often overlook: a standardized 15-minute break occurs after Testlet 3, and the clock stops during that break, so it doesn't eat into your four hours of testing time. Any other breaks you take during the appointment do count against your available time, so pacing your testlets matters.
A key content-scope note: candidates are not tested on specific tax rate percentages, dollar amounts, or limitations that are indexed to inflation. The exam instead focuses on the conceptual mechanics - how a rule works, not the exact number attached to it in a given tax year. This is worth internalizing early, because it changes how you build flashcards and practice questions; memorizing a specific bracket or phase-out figure is far less valuable than understanding the structure of the rule itself.
Also relevant for anyone studying in 2026: provisions of H.R. 1 with 2024 or 2025 effective dates became eligible for REG testing on July 1, 2026. If your study window straddles that date, confirm which version of the content you're being tested on and adjust your materials accordingly.
For a deeper look at what makes the exam challenging beyond raw content volume - pacing, simulation complexity, and question style - see How Hard Is the REG Exam? Complete Difficulty Guide 2026.
Registration, Fees, and Scheduling Mechanics
Before you can sit for REG, you need board approval and a Notice to Schedule (NTS) from your jurisdiction. Eligibility rules, credit windows, and CPE requirements are all set by individual state boards, so the exact path varies depending on where you're licensing.
On cost: in NASBA CPA Examination Services jurisdictions, the REG exam-section fee is $268.59. This is separate from application or board fees, which are set independently by each jurisdiction - meaning your total out-of-pocket cost depends heavily on where you apply. A full cost breakdown, including how section fees and application fees stack up, is available in REG Certification Cost 2026: Complete Pricing Breakdown.
Because eligibility and NTS issuance are jurisdiction-specific, it's worth confirming your state board's exact process before you schedule anything through Prometric. For scheduling windows and how testing dates work throughout the year, see REG Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
Scoring: What "Passing" Really Means
REG scores are reported on a 0-99 scale, and a passing score is 75. This is a common point of confusion: 75 does not mean you answered 75% of questions correctly. The scoring model weights questions by difficulty and combines MCQ and TBS performance (50% each) into a scaled score, and scores are not curved against other candidates in your testing window.
For the most recent data point available, the cumulative Q1-Q2 2026 pass rate for REG was 66.78%. That figure reflects candidates across a full six-month window, not any single testing session, so treat it as a general benchmark rather than a guarantee for any individual sitting.
Key Takeaway
A score of 75 is a scaled result, not a percentage of correct answers - focus your prep on consistent performance across both MCQs and TBSs rather than chasing a raw "percent correct" target.
If you want the full mechanics of how the scaled score is calculated and what a 75 actually represents statistically, REG Passing Score 2026: Exactly What You Need to Pass covers it in detail. For historical and comparative pass-rate context, see REG Pass Rate 2026: What the Data Shows.

Who Hires People Who've Passed REG
Passing REG is one component of becoming a licensed CPA, and CPA licensure itself is what employers ultimately value - public accounting firms, corporate tax departments, and advisory practices all look for candidates progressing through or having completed the full CPA Exam. Because REG specifically covers taxation, business law, and entity/individual tax mechanics, it signals readiness for roles centered on tax compliance, tax planning, and regulatory/procedural work within a firm's tax practice.
Candidates working toward licensure often use REG progress as evidence of technical tax competency even before full licensure is complete, since the domain content maps directly onto day-to-day tax preparation and review tasks. For more on how this section connects to career trajectory and compensation expectations, see REG Salary Guide 2026: Complete Earnings Analysis and REG Jobs.

Building a REG-Specific Study Plan
Generic study techniques only help if they're mapped onto REG's actual weight distribution. Given that Federal Taxation of Entities (23-33%) and Federal Taxation of Individuals (22-32%) together dominate the score, your calendar should front-load those two domains rather than spreading time evenly across all five.
Federal Taxation of Individuals
- Income inclusions/exclusions, deductions, credits, filing status rules
- Practice MCQs daily; save TBS practice for once concepts are stable
Federal Taxation of Entities (including tax preparation)
- Entity formation, distributions, liquidations, return preparation logic
- Run full TBS scenarios since this domain leans heavily on simulations
Business Law + Property Transactions
- Contracts, agency, entity legal structure
- Basis and gain/loss characterization
Ethics, Professional Responsibilities and Federal Tax Procedures + Full Reviews
- Practitioner conduct and procedural rules
- Full-length mixed practice sets under four-hour timing
Whatever schedule you build, treat timed, mixed-domain practice as non-negotiable in the final weeks - the real exam mixes all five domains across five testlets, and practicing them in isolation won't prepare you for the switching cost of moving between Business Law and entity taxation mid-appointment. Our practice test platform is built around this exact five-testlet structure so your rehearsal matches exam-day pacing.
