The Regulation (REG) CPA Exam section primarily covers three topics: business law, ethics, and federal taxation. The topic that receives the most attention is federal taxation in its various forms, which makes up over half of the exam!
REG recently underwent some major changes thanks to the Tax Cuts and Jobs Act (TCJA). The TCJA is the most significant modification to the tax code since 1986 and will have far-reaching effects on accountants everywhere for years to come.
The AICPA wants to know you can perform tax preparation and other services commonly required of CPAs. So to pass the REG CPA Exam, you’ll need to become familiar with tax law—but you’ll need to do more than memorize. Plan on reviewing material and then spending time working through questions and simulations that let you apply the rules you’ve learned.
The rest of this guide will equip you with what you need to know to prepare for the REG section of the CPA Exam. If you’re already studying, check out some of our free webinars and videos or make use of our free REG questions. You’ll also find here some study tips specifically for REG.
Setting aside the sharp dip in 2011, pass rates for REG have been relatively stable. REG is consistently the section with the second or third highest pass rate (competing with AUD). FAR had the lowest pass rate in 2018 at 46%, and BEC had the highest at 59%. The exact pass rates shift a bit from year to year, but the CPA Exam sections’ relative difficulty historically has followed that dynamic for the past several years.

Did you know? Since 2006, the lowest pass rate REG has reported in one quarter has been 39%, and the highest has been 57%. That 57% is from Q3 of 2018, and we’re hopeful strong performances will continue throughout 2019.

The REG CPA Exam section consists of five testlets: two testlets of multiple-choice questions (MCQs) and three testlets of task-based simulations (TBSs). The MCQ portion of REG accounts for 50% of your CPA Exam score, and the TBS portion accounts for the other 50%.
REG Format Breakdown
Testlet 1 38 MCQs
Testlet 2 38 MCQs
Total MCQs: 76 | Scoring: 50%
Testlet 3 2 TBSs
Testlet 4 3 TBSs
Testlet 5 3 TBSs
Total TBSs: 8 | Scoring: 50%
Testing Time 4 hours + 15 min break
The AICPA prescribes two levels of difficulty to MCQ testlets: “medium” and “difficult.” This indicates the average difficulty of questions within the testlet. Like the other CPA Exam sections, the second REG MCQ testlet adapts to your performance on the first.
According to the AICPA, there isn’t an advantage or disadvantage to receiving harder or easier questions because the exam takes question difficulty into account during grading.
In short, harder questions are worth more points.
The first MCQ testlet you receive will be of medium difficulty. The difficulty of the next testlet is determined by your performance on the first.
If you perform well on the first testlet, you will receive a difficult testlet. If you do not perform well on the first testlet, you will receive another medium testlet.
You can encounter a very difficult question in a medium testlet or a relatively easy question in a difficult testlet. It’s not worth using valuable testing time trying to figure out the difficulty of your second MCQ testlet.
Your performance on MCQ testlets does not impact how difficult your TBS testlet will be. TBS testlets are pre-selected.

Most REG testlets include operational and pre-test questions. Operational questions count toward your total exam score, and pre-test questions do not. That said, you can’t tell which questions are which so don’t waste any valuable testing time trying to decide whether you can afford to skip a question!
REG Question Categories
The AICPA looks to continuously evolve and improve the CPA Exam. Pre-test questions are potential future exam questions the AICPA is trying out by inserting them among real exam questions on REG and other CPA Exam sections. This lets it study how suitable the questions will be for future use.
The AICPA already knows what topics the operational questions test and how difficult they are, so it can analyze candidate performance on pre-test questions with the operational questions serving as a sort of control. While no one likes to be a guinea pig for experiments—especially on an exam this difficult—keep in mind that your score on these questions will not count.
The pre-test questions that meet the AICPA’s standards are included as operational questions on later iterations of the exam. This pre-test period is also used to assign a difficulty level to questions for grading purposes, and questions continue to undergo statistical analysis based on the live exam.
Pre-test questions may be more difficult than operational questions, but because you can’t tell which are which, it’s best to answer all questions as best you can. If it helps, whenever you encounter a really difficult question and aren’t sure of your answer, just tell yourself it’s probably a pre-test question and keep moving!
Computers grade all CPA MCQ and TBS testlets. Your final score is scaled according to the difficulty of the MCQs you answered correctly, your credit on the TBSs, and the weights assigned to the different types of testlets. (See more on how the CPA Exam is scored.)
The passing score for all CPA Exam sections is 75 points or higher. This does not necessarily mean you need to answer 75% of questions correctly.
Difficult MCQs are worth more points, so a strong performance on the first MCQ testlet can give you an opportunity to earn even more points in the second MCQ testlet. Difficult questions are also more time-consuming, so you’ll need to practice a time-management strategy to optimize your score.
The CPA Exam is not curved in the same way as other exams you might have come across in your accounting studies. Instead of adjusting your score based on how your cohort does, the AICPA uses question weights. These weights are assigned based on how candidates fared with the questions on previous exams. So your score is impacted by the performance of past test takers–but not current.
It’s worth repeating here that your score is not a percent. You don’t have to get 75% of the questions right—you just need a score of 75. If you think you’re borderline passing, you’re probably fine. A 65% may in fact be 75 points after it’s scaled.
Yes, you can receive partial credit on TBSs! Never leave any part of a question blank on REG (or other sections for that matter), and always double-check to make sure you’ve answered all parts of a question. No two TBSs are the same. They can have wildly different formatting and require you to input your answer in different ways, so stay sharp.
Passing REG requires a strong understanding of ethics, business law, and federal taxation. The content is sourced from many different acts, regulations, etc., including:
The AICPA publishes CPA Exam Blueprints that specify exactly what a CPA needs to know for REG, all the way down to specific tasks. The subject matter is divided into six content areas.
|REG Exam Syllabus
For a breakdown on the exam contents click the links below
Ethics, Professional Responsibilities and Federal Tax Procedures
10%-20% Ethics, Professional Responsibilities and Federal Tax Procedures
10%-20% Business Law
Federal Taxation of Property Transactions
12%-22% Federal Taxation of Property Transactions
Federal Taxation of Individuals
15-25% Federal Taxation of Individuals
Federal Taxation of Entities
28%-38% Federal Taxation of Entities
It’s good to look over the higher-level concepts to get a broad idea of what you should be taking away from your studies, but the Blueprints aren’t really useful for candidates who want to make a study plan. The Blueprints are incredibly detailed, and if you were to go through them on your own, you’d likely spend just as much time figuring out what to study and how much time to devote to each topic as you would actually preparing for the exam.
Tax laws are frequently amended, so the AICPA has specific guidelines for updating the relevant REG questions. Per the AICPA, “changes in the federal taxation area, the Internal Revenue Code, and federal taxation regulations may be included in the testing window beginning six months after the change’s effective date or enactment date, whichever is later.” In other words, federal laws are generally eligible to be tested in the testing window beginning six months after their effective date.
In our experience, the AICPA does not appear to hold hard and fast to these rules.
For example, you may see tax forms from prior years on your REG task-based simulations(TBSs), but don’t be distracted by dates. Simply complete the form to the best of your ability. If the exam provides an out-of-date tax rate, use that rate to answer the question.
Also, be aware that the auditing, financial, and tax research databases presented as Authoritative Literature in the TBSs are updated on the AICPA’s schedule and may also appear out-of-date. Again, you should use the research database as presented, even if you know there’s a recent change to the literature but you don’t see it there there.
The Gleim CPA Review Course is automatically updated to reflect the latest material that could appear on the CPA Exam.
The AICPA states “materials eligible to be tested include federal laws in the window beginning six (6) months after their effective date, and uniform acts in the window beginning one (1) year after their adoption by a simple majority of the jurisdictions.”
The AICPA began testing 2018 tax law changes on January 1, 2019.
The REG section of the CPA Exam isn’t easy (none are). One factor contributing to CPA Exam difficulty is the fact that the exam assesses candidates at four different levels of skill. The pass rate for REG hovers around 50%, so it’s important to make sure you have a firm grasp of the subject matter.
Each skill level builds on the preceding one. The REG CPA Exam takes a balanced approach to testing at every skill level (except for Evaluation, which is only tested in AUD).
REG and FAR test Analysis more than AUD and BEC. Analysis is one of the more difficult skill levels on the CPA Exam, but it is not hard to master when you review with a thorough CPA review course featuring the best test bank on the market. Gleim CPA Review covers the exam content better than any other course, and our high-quality practice simulations will help you achieve the analysis level of skill quickly and effectively.
If you have tax experience, REG may be the section you should take first. A good deal of REG content will be familiar to candidates who have had internships or worked in a public tax practice. If this describes you, or if you’re planning to begin work at a tax firm in the near future, consider scheduling this section early to build confidence. The knowledge you gain will be a great asset to you in your professional career.
For candidates without much tax experience, REG can be fairly tricky because there is a lot of material you must memorize before you can begin to apply it at a high level. The BEC, FAR, and AUD CPA Exam section content overlaps somewhat, so it’s usually best to schedule those sections close to one another. If you are not comfortable taking REG first, consider scheduling it last.
As you plan when to take the different sections, we recommend starting with the one you’re most familiar with to help position you for an early win. This can give you confidence and let you get used to the CPA Exam a little more comfortably.
The total testing time for REG is four hours, the same as the other CPA Exam sections. The five testlets of the REG CPA Exam section are independent. There are no time limits on the individual testlets, so it is up to you to manage your time appropriately so that you can complete all five testlets before the exam ends.
Based on the total time of the exam and the amount of time needed to complete each testlet, you should plan to spend:
1.25 minutes each
18 minutes each
REG Time Allocation by Testlet
Time (in minutes)
|15-minute break (does not count toward total exam time)|
|Total||76 MCQs / 8 TBSs||240|
As you can see from the small amount of extra time left over, this schedule is very tight. That’s because REG has more MCQs than any other exam section. Straying from this schedule greatly reduces your chances of passing. Do whatever you can to keep to a strict time management system. This includes making educated guesses when necessary and not stressing about difficult questions (remember, they might be pre-test questions!).
It will take a lot of practice to get to a place where you can answer questions this quickly. But as you learn the material and complete more sample questions, you’ll build mastery of the topics and get faster.
Use any extra time you have available. Those four hours are yours! Don’t risk leaving any points on the table.

We’ve compiled some of our top tips for the REG CPA Exam section.
1. Study early; study often.
Your exam score on REG will reflect the amount of time you put in, so put in as much time as you can and make the most of it. The most successful candidates know the huge effect stress and fatigue can have on their performance, so they set up a study calendar that accounts for their lifestyle and sleeping habits. An interactive study planner like Gleim’s lets you set a realistic schedule for your study sessions. Our study planner also tracks your performance, even making it possible for our personal counselors to support you right where you are in your studies.
2. Become familiar with federal taxation, especially income, gift, and estate taxation.
More than 70% of the REG exam focuses on federal taxation. If you’ve had coursework focused on taxation or worked in a public tax practice, you have an advantage. If you haven’t, don’t worry. Gleim CPA Review has the tools you need to master REG tax topics.
3. Practice applying concepts.
Rote memorization comes in handy on REG, but now more than ever the AICPA is testing candidates at a higher level. You’re expected to show you have the skills to provide tax preparation and advisory services. You’ll find what you need in the Gleim CPA Review, with a powerful bank of highly acclaimed practice questions built right into the course.
