CPA REG Most Tested Topics: Tax and Law Focus Areas
Identify the most frequently tested topics on the CPA REG section. From individual taxation to business entities and ethics, know where to focus your REG preparation.
Navigating the REG Exam Content
The Regulation section covers federal taxation, business law, and professional ethics. Taxation dominates the exam, but business law questions can make or break your score if you neglect them. The REG exam rewards candidates who understand tax rules conceptually and can apply them to fact patterns, rather than those who simply memorize tax rates and thresholds.
This guide identifies the topics that appear most frequently on the REG exam based on the AICPA blueprint and candidate experience, helping you build a targeted study plan.
Top Tier: The Heaviest-Tested REG Topics
Individual Taxation
Individual tax is the single largest content area on REG. Gross income inclusions and exclusions, above-the-line and below-the-line deductions, filing status determination, and tax credit calculations all appear heavily. You need to understand the standard deduction versus itemized deductions, the treatment of capital gains and losses (including netting rules and the $3,000 annual limitation), and passive activity loss rules. Qualified business income deduction under Section 199A is a commonly tested newer provision.
Entity Taxation: Partnerships and S Corporations
Pass-through entity taxation is heavily tested because of its complexity and practical importance. For partnerships, you must master formation rules (contribution of property and services), allocation of income and loss, basis calculations (including at-risk and passive activity limitations), guaranteed payments, distributions (current and liquidating), and sale of a partnership interest. S corporation taxation covers similar ground but with its own rules for eligibility, election, basis calculations (stock and debt basis), and distributions from accumulated adjustments accounts.
Entity Taxation: C Corporations
C corporation topics include formation under Section 351, taxable income computation, dividends received deduction, accumulated earnings tax, personal holding company rules, and corporate distributions. Liquidation and reorganization transactions also appear, though less frequently than operating topics. The relationship between book income and taxable income through Schedule M-1 and M-3 adjustments is a reliable exam topic.
Second Tier: Consistently Tested Topics
Property Transactions
Basis determination, gain and loss recognition, and characterization of gains and losses (ordinary, Section 1231, capital) are tested extensively. Like-kind exchange rules under Section 1031, involuntary conversions under Section 1033, and installment sales under Section 453 are common topics. Depreciation methods including MACRS, Section 179 expensing, and bonus depreciation also appear regularly. Related party transaction rules under Sections 267 and 707 are tested as well.
Business Law: Contracts and Agency
Contract formation, performance, breach, and remedies are consistently tested business law topics. You should understand offer and acceptance, consideration, the statute of frauds, the parol evidence rule, and the difference between material and minor breaches. Agency law, including the creation of agency relationships, agent authority (actual, apparent, and inherent), and principal liability for agent acts, is also a reliable exam area.
Professional Ethics and Responsibilities
Circular 230 rules governing practice before the IRS are tested on REG. You should know the due diligence requirements, return preparer penalties, and the rules for providing tax advice. The differences between tax return positions and tax shelter opinions matter here. AICPA Statements on Standards for Tax Services also appear.
Third Tier: Moderate Testing Frequency
Estate, Gift, and Trust Taxation
While not as heavily tested as income taxation, estate and gift tax concepts do appear. The unified credit, annual exclusion, marital deduction, and charitable deduction are key concepts. Trust and estate income taxation, including distributable net income and the distribution deduction, is tested at a conceptual level. Simple versus complex trust distinctions appear occasionally.
Business Law: Business Structures and UCC
The formation, operation, and dissolution of partnerships, corporations, and limited liability companies are tested from a legal (not tax) perspective. UCC Article 2 (sales) and Article 9 (secured transactions) concepts appear, including perfection of security interests, priority of claims, and rights of buyers in the ordinary course of business.
Tax-Exempt Organizations
Section 501(c)(3) requirements, unrelated business taxable income, and private foundation rules appear with moderate frequency. These topics are usually tested at a high level rather than with detailed calculations.
REG Study Priorities
Build a Strong Tax Foundation First
Start your REG study with individual taxation because it provides the conceptual foundation for entity taxation. Many concepts, such as basis, at-risk limitations, and passive activity rules, apply across entity types. A strong understanding of individual tax makes partnership and S corporation topics significantly easier.
Do Not Neglect Business Law
Business law typically accounts for 15 to 25 percent of the REG exam. Candidates who skip business law to focus exclusively on taxation are gambling with their score. Business law questions tend to be more straightforward than tax questions, making them a good source of points if you have studied the material.
Practice Tax Computations
REG simulations often require you to compute basis, determine gain or loss, or prepare portions of a tax return. Practice these calculations under timed conditions to build speed and accuracy. Pay special attention to partnership and S corporation basis calculations, as these are common simulation topics.
