Taxation and Regulation (REG)
Use the REG guide to connect ethics, business law, property transactions, and federal taxation across individuals and entities.
REG tests more than recall of tax rules. The section depends on recognizing which authority applies, what the transaction does to basis or character, and how legal and procedural constraints shape the answer. This guide is arranged so you can move from professional responsibilities into business law and then through the major federal tax areas.
Chapter Map
Part I: Introduction and Exam Overview for the section structure and the broad logic of REG study.
Part II: Ethics, Professional Responsibilities, and Federal Tax Procedures for Circular 230, responsibilities to clients and the IRS, and procedural foundations.
Part III: Business Law for contracts, agency, debtor-creditor issues, and legal relationships that drive REG reasoning.
Part IV: Federal Taxation of Property Transactions for basis, gain or loss recognition, nonrecognition rules, and transaction consequences.
Part V: Federal Taxation of Individuals for gross income, deductions, credits, and individual-return logic.
Part VI: Federal Taxation of Entities for corporations, partnerships, S corporations, and entity-level rules.
Part VII: Advanced Topics in Tax Planning and Strategy for higher-order planning considerations.
Part VIII: Property Dispositions and Special Transactions for additional transaction patterns that candidates commonly confuse.
Part IX: Practical Insights and Additional Resources for later-stage review support.
REG questions should be solved by identifying the legal or tax relationship first. A fact pattern may look computational, but the controlling issue can be authority weight, taxpayer status, business-law rights, basis, character, entity form, or practitioner responsibility. The guide is designed to make those distinctions explicit before final review.
REG Study Lens
REG task
What to decide
Common trap
Ethics and procedure
Which professional duty, IRS process, deadline, or penalty rule applies.
Treating a procedural constraint as background information.
Business law
Which legal relationship creates rights, obligations, liability, or remedy.
Ignoring legal status because no tax computation is required.
Property transactions
Amount realized, adjusted basis, character, recognition, and deferral.
Calculating gain before checking nonrecognition or related-party rules.
Individual and entity tax
Which taxpayer or entity framework controls income, deduction, basis, and reporting.
Applying individual rules to an entity or pass-through rules to a C corporation.
Planning and review
Whether the answer is defensible under authority, timing, documentation, and future consequences.
Choosing the lowest tax result without checking support or later effects.
REG Issue-Order Checkpoints
Checkpoint
Ask before answering
Why it improves REG accuracy
Relationship
Is the controlling relationship practitioner-client, taxpayer-IRS, debtor-creditor, principal-agent, owner-entity, or buyer-seller?
REG often tests legal status before tax computation.
Authority
Which statute, regulation, IRS guidance, court rule, or professional standard controls the issue?
A plausible tax answer can be wrong if it relies on the wrong authority.
Taxpayer framework
Is the relevant taxpayer an individual, C corporation, S corporation, partnership, estate, trust, or exempt organization?
Entity form changes income, deduction, basis, allocation, and filing treatment.
Transaction effect
What changes in basis, character, timing, recognition, liability, or documentation?
Most computational REG questions are controlled by the transaction’s legal effect.
Support and future consequence
What record, disclosure, carryover, election, or later-year result follows from the answer?
The best answer usually accounts for both current result and compliance support.
How to Use This Guide
Read Parts II through VI as the core REG spine.
Use Parts VII and VIII after the main framework is stable so planning and special-transaction rules have context.
Return to Part IX near review phase, not as a substitute for the main tax and law lessons.
