CPA REG 2026: A No-Nonsense Guide for Tax Beginners

The Section Nobody Feels Ready For

I walked into REG thinking I had a reasonable grip on taxes. I'd filed my own return. I understood the concept of a W-2. I once confidently explained what a 1099 was at a dinner party. I was, in other words, completely unprepared.

REG — the Regulation section of the CPA exam — is the section that humbles people who think they've done their homework and destroys people who haven't. According to NASBA data, REG consistently posts one of the lower pass rates among the four exam sections, hovering in the low-to-mid fifties percentile range in recent testing windows. That's not a coincidence. REG covers an enormous amount of conceptually dense material: individual taxation, corporate and partnership taxation, business law, ethics, and federal tax procedures. It does all of this at a level of specificity that makes your average tax prep software look like a coloring book.

If you have no tax background, none of this needs to scare you. But it does need to get your attention.

What REG Actually Tests

The 2026 exam blueprint breaks REG into several distinct content areas, and understanding the weighting is half the battle. Federal taxation of individuals represents roughly 15–25% of the exam. Entity taxation — covering C corporations, S corporations, partnerships, and trusts — accounts for another 28–38%. Business law (contracts, agency, secured transactions, bankruptcy) sits at around 10–20%. Federal tax procedures, professional responsibilities, and ethics round out the rest.

That breakdown matters because candidates with no tax background tend to make the same mistake: they treat every topic as equally important. They spend three weeks mastering at-risk rules for partnerships and then get blindsided by a contracts question involving the Statute of Frauds. REG does not reward specialists. It rewards people who can hold a wide map in their head while still zooming in on the details that matter.

Starting with Individual Taxation

If you've never studied tax before, individual taxation is where you build your foundation — and it's also where most of the conceptual architecture lives. Everything else you learn in REG will make more sense once you understand how the individual income tax system works.

Start with gross income and work outward. The rule that everything is included in gross income unless specifically excluded sounds simple until you realize the IRC has approximately one million specific exclusions, each with its own conditions. Get comfortable with the difference between deductions for AGI (the ones that make your adjusted gross income smaller before you even get to the standard deduction) and deductions from AGI (itemized deductions). This distinction matters enormously on the exam and confuses candidates endlessly in practice.

Passive activity rules, capital gains and losses, and the alternative minimum tax are the three areas where candidates without a tax background tend to lose the most points. They're also the areas where a little focused attention pays outsized dividends. The AMT, in particular, feels like the tax code's way of saying "just kidding" to people who thought they'd calculated their liability correctly. Learn it early. Don't fight it.

Corporate and Entity Taxation

Once you've built your individual tax foundation, C corporation taxation starts to feel almost logical. Almost. The core concept — that a C corp is a separate taxable entity that pays its own taxes, and then shareholders pay taxes again on dividends — is the foundation of double taxation, and the exam will test whether you really understand it rather than just recognize the phrase.

S corporations and partnerships are where REG gets genuinely tricky for newcomers. Both are pass-through entities, meaning the entity itself doesn't pay federal income tax — instead, income, losses, deductions, and credits flow through to the owners' individual returns. The exam loves to test the subtle differences between how S corps and partnerships handle this pass-through treatment. Basis is the concept at the center of almost every entity taxation question. If you don't understand how a partner's or shareholder's basis works — how it increases, how it decreases, and why it matters for loss deductions and distributions — you will get these questions wrong. It's not optional knowledge.

Business Law: The Section Within the Section

Here's where REG gets interesting in a way that surprises people. Business law questions aren't accounting questions. They test contracts, agency relationships, secured transactions under the Uniform Commercial Code, and federal bankruptcy law. For candidates coming from an accounting background, this section can feel like showing up to a math exam and finding an essay question about maritime history.

The good news is that business law on REG is testable in a finite, predictable way. Contracts questions follow patterns — offer, acceptance, consideration, defenses, breach, remedies. Agency questions focus on actual versus apparent authority and the conditions under which a principal is liable for an agent's actions. Secured transactions test whether a security interest has been properly attached and perfected. Bankruptcy questions focus on Chapter 7 liquidation and Chapter 11 reorganization, with a particular emphasis on the automatic stay and the priority of creditor claims.

Spend roughly one week on business law — no more, no less. The content is learnable, but it's not worth cannibalizing the time you need for taxation.

How to Actually Study This Material

The candidates who pass REG aren't necessarily the ones who study the longest. They're the ones who study with the most feedback. This is where practice questions become genuinely essential rather than just a nice supplement to reading.

Here's what an effective REG study cycle looks like in practice. Read a topic. Test yourself immediately. Review every wrong answer — not just to learn the right answer, but to understand *why* you were wrong. Then return to the topic with that corrected understanding. Passive reading of REG content produces the illusion of competence. Active retrieval is what actually builds it.

There's a reason platforms like Sophos Academy structure their free practice questions by specific topic area — so you can immediately identify whether you actually understand basis calculations or just think you do. That distinction, discovered early, is what keeps you from walking into the real exam with a false sense of security.

For pacing, plan for 300–400 hours of total study time if you're starting from no tax background. That's not a number designed to frighten you. It's a number designed to help you build a realistic schedule. REG rewards consistent daily engagement far more than heroic weekend cramming sessions.

The Week Before the Exam

The week before REG, stop trying to learn new things. Review, consolidate, and simulate. Work through timed mock exams under real testing conditions — meaning no phone, no notes, and no pausing the clock because you want to look something up. Sophos Academy's timed mock exams replicate the format and pressure of the actual exam in a way that reading about the exam simply cannot. Simulated discomfort before the real thing is one of the most underrated preparation strategies in exam prep.

One final note on the task-based simulations (TBS): REG's simulations require you to apply knowledge in context, often across multiple steps. Candidates who only drill multiple-choice questions tend to be underprepared for this portion. Make sure your simulation practice matches the weight the exam actually gives it.

What to Do Next

The best time to take your first REG practice question is before you feel ready — because feeling ready and being ready are not the same thing, and only one of them is measurable. Head to [sophosacademy.org/practice](https://sophosacademy.org/practice) to access free practice questions organized by REG content area, and when you're ready to stress-test your full exam readiness, the timed mock exams at [sophosacademy.org/mock-exams](https://sophosacademy.org/mock-exams) will tell you exactly where you stand before it counts.
