The Regulation (REG) section of the CPA exam is a unique beast. It blends federal taxation, business law, and ethics into a single four-hour testing window, and candidates often wonder where it falls on the difficulty spectrum. One of the most useful lenses for answering that question is the REG pass rate, which tells you what percentage of first-time and repeat testers actually walk away with a 75 or above. In this analysis we will break down the latest pass rate data, explain the trends behind the numbers, and give you a concrete plan for making sure you land on the right side of the curve.
REG Pass Rate Trends: A Multi-Year Snapshot
Over the past several years the REG pass rate has consistently hovered in the range of 55 to 65 percent, making it one of the higher-performing sections on the CPA exam. In recent testing windows the rate has settled around 60 percent, which is notably above FAR and roughly on par with AUD. To understand what that number really means, you need to appreciate the context.
The AICPA releases pass rate data on a quarterly basis. Here is a simplified look at the approximate REG pass rates from recent years:
- 2022: 59.3 percent cumulative pass rate
- 2023 (pre-Evolution): 61.4 percent cumulative pass rate
- 2024 (post-Evolution): 60.8 percent cumulative pass rate
- 2025 Q1 estimate: 59 to 62 percent based on early data
Notice the relative stability. Even when the AICPA transitioned to the CPA Evolution model in January 2024, which changed the other sections more dramatically, REG remained fairly consistent. That stability is a clue about the nature of the section itself.
Why Does REG Have a Higher Pass Rate?
Compared to FAR, which has regularly posted pass rates in the low-to-mid 40s, REG looks almost friendly. Several factors contribute to that differential.
Familiarity With Tax Concepts
Many CPA candidates enter the exam after working in public accounting, and a significant portion of entry-level public accounting work involves tax returns. Whether it is preparing individual 1040s or assisting with corporate 1120s, these candidates have a baseline comfort with the terminology and logic of taxation. That practical exposure translates into a meaningful head start on the exam.
Narrower Content Scope
REG covers a large amount of material, but it is concentrated in two major domains: taxation and business law. Compare that to FAR, which sprawls across financial accounting, governmental accounting, not-for-profit accounting, and various specialized topics. The relative focus of REG allows candidates to study more efficiently and build mastery in a smaller number of subject areas.
Structured Study Materials
Tax law, despite its complexity, is highly structured. The Internal Revenue Code follows a logical hierarchy, deductions follow rules, and phase-outs follow formulas. Candidates who like structured, rule-based content tend to find REG more manageable than the more conceptual sections like AUD.
What Makes REG Unique Among CPA Sections
Even though the pass rate is relatively favorable, REG is not a section you can sleepwalk through. It has its own brand of difficulty that catches candidates off guard.
- Constant law changes: Tax law is updated annually. You must study based on the law in effect for your testing window, and the AICPA regularly updates the exam blueprints to reflect legislative changes.
- Heavy calculation load: Unlike AUD, where much of the content is conceptual, REG requires you to grind through numbers. Basis calculations, gain or loss determinations, and phase-out computations demand precision.
- Business law integration: Roughly 10 to 20 percent of REG involves business law, covering agency, contracts, the Uniform Commercial Code, and debtor-creditor relationships. Candidates who focus exclusively on tax can lose easy points here.
- Ethics and professional responsibilities: Circular 230 and AICPA ethics standards appear on REG and are testable. These topics are straightforward but are often under-studied.
The Tax Law Challenge: Staying Current
One of the trickiest aspects of REG is that the tax code changes frequently. Major legislation like the Tax Cuts and Jobs Act of 2017, the CARES Act of 2020, and the Inflation Reduction Act of 2022 each introduced provisions that altered how individuals and businesses are taxed. The AICPA typically tests on the law in effect as of a certain cutoff date, and you need to confirm which provisions are testable during your testing window.
This means that study materials from even one year ago may contain outdated phase-out thresholds, contribution limits, or credit amounts. Always verify that your review course reflects the current testing window before you begin studying.
Strategies for Passing REG on Your First Attempt
Here is a battle-tested plan for conquering REG:
- Master basis calculations. Basis is the backbone of REG. If you understand how to compute the adjusted basis for individuals, partnerships, S corporations, and C corporations, you will be equipped to answer a wide variety of questions.
- Do not ignore business law. It may feel less important than tax, but 10 to 20 percent of the exam is significant. A focused week of study on contracts, agency, and secured transactions can net you reliable points.
- Practice task-based simulations daily. REG simulations often require you to compute a tax liability, determine a gain or loss, or classify a transaction. The more you practice in a realistic format, the faster and more accurate you will be on exam day.
- Study with current-year materials. Outdated tax figures can cost you points. Make sure your course is updated for the latest testing window.
- Focus on the high-weight blueprint areas. Federal taxation of individuals and entities together make up the majority of the exam. Allocate your study time proportionally.
How to Interpret Pass Rate Data for Your Own Preparation
A 60 percent pass rate means that roughly 4 out of 10 candidates fail. That is not a trivial failure rate. The candidates who pass are not smarter than those who fail. They are better prepared. They studied with a plan, they practiced under timed conditions, and they addressed their weak areas instead of reviewing material they already knew.
If you are a candidate with a tax background, the pass rate suggests that REG is a strong section to start with because your existing knowledge base gives you an advantage. If your background is in audit or advisory, expect to invest more hours in learning the tax rules from scratch, but know that the structured nature of the material is on your side.
Where Think CPA Fits Into Your REG Strategy
At Think CPA, we build our REG study materials around the areas that the exam tests most heavily. Our practice questions mirror the AICPA blueprint, our simulations replicate the calculation-intensive format of the real exam, and our content is updated every testing window to reflect the latest tax law. If you are serious about passing REG on your first try, a structured study plan combined with high-quality practice is the most reliable path forward.
Final Takeaways
The REG pass rate is among the highest of all CPA exam sections, but that does not mean the section is easy. It means that the material rewards disciplined, focused study. Master the tax rules, practice the calculations, cover business law, and use current materials. Do those things consistently and you will put yourself in a strong position to pass.
