What does the REG CPA section test?

Taxation and Regulation covers Ethics, Professional Responsibilities and Federal Tax Procedures; Business Law; Federal Taxation of Property Transactions; Federal Taxation of Individuals; Federal Taxation of Entities (including tax preparation). A tax answer depends on the taxpayer, transaction, period, character, and applicable limitations. Build those classifications into your workpaper so a familiar formula does not lead you to answer the wrong question.

How long is REG, and how many questions are on the exam?

REG has 4 hours of testing time, 72 MCQs, and 8 task-based simulations. The two MCQ testlets contain 36 and 36 questions. The three simulation testlets contain 2, 3, 3 TBSs.

How is REG weighted between MCQs and simulations?

MCQs contribute 50% of the section score and TBSs contribute 50%. The content-area ranges describe a different dimension: how the tested content is allocated across the blueprint. Neither set of percentages is a personalized study-time plan.

Is REG required for every CPA candidate?

REG is a required Core section, alongside the other two Core sections. Candidates also select one Discipline from BAR, ISC, and TCP.

Do I need an account for these REG questions?

No. All 5 questions, answer checking, explanations, progress, and reset controls on this page work without an account. Create a MiloPrep account to continue learning with lessons, videos, flashcards, and more practice.

Are these official AICPA exam questions?

These are independently authored questions from the MiloPrep question bank. The AICPA blueprint defines the exam scope and format; it is not the source of these practice items.

Does this practice set cover the full REG blueprint?

This 5-question set is a starting point for practice and explanation review. It does not cover every blueprint task or predict an exam score. Use the linked REG study guide and official 2026 blueprint to plan complete coverage.

What does REG test?

REG combines tax ethics and federal procedures, business law, and federal taxation of property, individuals, and entities. It tests whether you can identify the relevant parties and rules before calculating or choosing a legal consequence.

A tax answer depends on the taxpayer, transaction, period, character, and applicable limitations. Build those classifications into your workpaper so a familiar formula does not lead you to answer the wrong question.

How to study these skills

Classify first, calculate second. Record the taxpayer, tax year, transaction, basis, character, and requested output. Work through limitations in order and verify that the rule version matches the period in the question.

REG content areas and exam percentages

The AICPA blueprint effective January 1, 2026 defines these content areas and allocation ranges. Use every area in your study plan, then spend additional time where practice shows a gap.

REG blueprint content areas, study guidance, and allocation ranges
Content area and what to learn	Exam weight
Area I Ethics, Professional Responsibilities and Federal Tax Procedures	10-20%
Understand professional responsibilities in tax practice and the federal procedures governing taxpayers and practitioners. Practice focus: Identify the obligation or procedural consequence that applies to the parties in a tax-practice scenario.
Area II Business Law	15-25%
Connect legal relationships to rights, duties, and remedies. Distinguish the relevant parties and the facts that control a business-law outcome. Practice focus: Classify the relationship before selecting a contractual obligation or legal remedy.
Area III Federal Taxation of Property Transactions	5-15%
Track basis and the tax consequences of property transactions. Separate the amount of a result from its character and the timing of recognition. Practice focus: Build a basis schedule before calculating the result of a property disposition.
Area IV Federal Taxation of Individuals	22-32%
Work through income, adjustments, deductions, and the tax calculation for individuals. Apply the relevant eligibility conditions and limitations. Practice focus: Trace a set of income and deduction items through the individual tax computation.
Area V Federal Taxation of Entities (including tax preparation)	23-33%
Distinguish entity forms and their federal tax treatment. Connect entity transactions and tax preparation to the requested entity or owner-level result. Practice focus: Identify the entity and the required output before applying a tax rule or preparing a calculation.

The ranges describe content allocation, not a guaranteed question count for each topic. The blueprint also lists representative tasks, skill levels, and references; its task list is not exhaustive.
