About this exam

The CPA Regulation (REG) section is one of the four core sections of the Uniform CPA Examination, the licensing exam that candidates must pass to become a licensed Certified Public Accountant in the United States. REG focuses on the rules that govern how tax and legal professionals actually work: federal tax procedures and ethical responsibilities, business law, federal taxation of property transactions, federal taxation of individuals, and federal taxation of entities. It suits candidates who are pursuing CPA licensure, typically accounting graduates and professionals working in public accounting, corporate finance, or tax. The section rewards precise, rule-based knowledge rather than broad conceptual reasoning, so preparation should combine systematic review of authoritative rules with heavy practice on multiple-choice questions and task-based simulations. Because the exam is periodically revised and administrative details such as question counts, testing time, passing scores, fees, and retake rules are set by the AICPA and state boards, candidates should confirm those specifics directly with the AICPA and their state board of accountancy rather than relying on secondhand summaries.

What you'll study

Common questions

About CPA REG preparation

What does the REG section actually test?

Five content areas: ethics, professional responsibilities and federal tax procedures; business law; federal taxation of property transactions; federal taxation of individuals; and federal taxation of entities. Individual taxation carries the largest weight, followed by entity taxation, so budget study time accordingly rather than spreading effort evenly.

How many questions and how much time?

We do not publish those figures here because exam specifications are revised periodically and must come from an authoritative, current AICPA source. Confirm the current number of multiple-choice questions, task-based simulations, and total testing time directly with the AICPA and your state board before you schedule.

What score do I need to pass, and how long is a passing score valid?

Passing scores and score-validity periods are set by the AICPA and individual state boards, and they change. Check your jurisdiction's board rules for the score required and how long a passed section remains valid toward licensure. Do not rely on figures remembered from older exam versions.

If I fail, how soon can I retake REG?

Retake rules, waiting periods, and fees vary by jurisdiction and are periodically revised. Verify the current policy with your state board of accountancy before assuming you can immediately reschedule. Build your study plan so a retake is a contingency, not part of the plan.

Is REG harder than the other sections?

Difficulty is personal, but many candidates find REG demanding because it requires memorizing many precise thresholds and rules across tax and legal topics with little room for approximation. Candidates comfortable with tax return mechanics and legal reasoning generally find it more tractable than those who prefer conceptual or computational sections.

What is the best study order within REG?

Start with individual taxation and property transactions, since they build foundational rules you will reuse. Move to entity taxation next, then finish with business law and ethics/tax procedures. Practicing mixed sets late in your review helps you switch between rule sets the way the exam requires.

How should I use practice questions?

Treat practice as diagnosis, not scoring. After each set, write down why every wrong answer was wrong and which rule it tested, then revisit that rule in your reference materials. Volume without review produces familiarity, not competence; spaced repetition of missed rules is what moves scores.

What are the most common failure modes?

Memorizing numbers without understanding the underlying rule, skipping business law and ethics because they feel peripheral, and neglecting task-based simulations in favor of multiple-choice drills. Simulations test application and research skills, so practice reading authoritative guidance and applying it to a fact pattern.

Where should I confirm official exam details?

Use the AICPA for exam content and administration information and your state board of accountancy for licensure, fees, and score validity. This page is an independent study resource and is not affiliated with or endorsed by the AICPA, CIMA, or any state board.
