Tax Practice Ethics and Circular 230
This topic covers practitioner duties, Circular 230 standards, conflicts of interest, due diligence, written advice, reliance, confidentiality, and sanctions.
How to study for CPA REG
Build every answer around taxpayer type, tax year, filing obligation, basis, character, limitation, and procedural consequence.
Core concepts
Concept 1
Tax Practice Ethics and Circular 230 questions test whether a CPA candidate can apply tax law, federal procedure, business law, or entity tax rules to a practical client fact pattern.
Exam cue: Identify the taxpayer type, tax year, transaction, return, authority, and dollar amount or deadline being tested.
Concept 2
The best REG answer usually identifies the taxpayer, transaction, year, tax basis, filing obligation, limitation, and procedural consequence before calculating.
Exam cue: Decide whether the task is inclusion, deduction, credit, basis, gain or loss, filing, penalty, representation, or legal liability.
Concept 3
Eliminate answers that skip statutory requirements, mix individual and entity rules, ignore basis, overlook filing deadlines, or choose a tax result without checking limitations.
Exam cue: Check limitations, character, timing, basis ordering, related-party rules, and whether the amount belongs on an individual or entity return.
Risk pitfalls and guardrails
Calculating taxable income before separating exclusions, adjustments, deductions, credits, and separately stated items.
Guardrail: Use a 15-second safety pause before finalizing your action.

Guardrail: Use a 15-second safety pause before finalizing your action.
Ignoring statute of limitations, preparer penalty, Circular 230, estimated tax, or filing-status details that control the answer.
Guardrail: Use a 15-second safety pause before finalizing your action.
Memory anchors
Circular 230
Circular 230 governs practice before the IRS for attorneys, CPAs, enrolled agents, and other practitioners.
Due Diligence
Due diligence requires reasonable care in preparing, approving, and filing tax documents and representations.
Conflict of Interest
A conflict may be waived only when representation is not prohibited and each affected client gives informed written consent.
Written Advice
Written tax advice must rely on reasonable assumptions, consider relevant facts, and not base conclusions on unreasonable representations.
Best Practices
Best practices include clear communication, reasonable inquiry, and advising clients about penalties and opportunities.
Confidentiality
Confidentiality limits use or disclosure of client tax information without proper consent or authority.
Contingent Fee
Contingent fees are restricted for many original return positions and allowed only in limited circumstances.
Sanction
Sanctions may include censure, suspension, disbarment, monetary penalty, or disqualification.
Return Position
A return position should meet the applicable authority and disclosure standard before being recommended.
Reliance
Reliance on another adviser is not reasonable when the practitioner knows or should know the advice is unreliable.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
