Explore the in-depth ethical requirements under Circular 230 and AICPA Standards, focusing on conflicts of interest, diligence, and confidentiality. Includes practical scenarios and detailed compliance guidance for tax professionals.
When it comes to representing clients in matters before the Internal Revenue Service (IRS) and delivering high-quality professional services, Certified Public Accountants (CPAs) must adhere to a robust set of ethical guidelines. These guidelines come primarily from two sources:
In this section, we will dive deeper into the ethical challenges CPAs commonly face—particularly around conflicts of interest, professional diligence, and client confidentiality. We also present “what-if” exam scenarios that help you understand how to navigate real test questions or real-world conundrums. An unwavering commitment to ethical behavior will not only help you pass the CPA exam but is essential for sustaining a reputable, long-term practice in public accounting.
Circular 230, administered by the Office of Professional Responsibility (OPR) under the U.S. Treasury, outlines standards for tax professionals authorized to practice before the IRS (including CPAs, attorneys, and enrolled agents). Key provisions and principles in Circular 230 address:
• Competence to practice.
• Due diligence requirements.
• Avoidance of conflicts of interest.
• Proper use of official tax forms and representations to the IRS.
• Disreputable conduct (penalties for misconduct).
• Fee restrictions and requirements (e.g., contingent fees in certain engagements).
Violations of Circular 230 can lead to censures, suspensions, or permanent disbarment from practice before the IRS. Compliance is, therefore, not optional—familiarity with its requirements is crucial for any CPA engaged in tax compliance and planning.
While Circular 230 is specific to representing taxpayers before the IRS, the AICPA Code of Professional Conduct has a broader scope that covers all facets of a CPA’s professional activities. Within the Code of Professional Conduct and the Statements on Standards for Tax Services (SSTS), key elements include:
• Integrity and Objectivity
• Independence (where applicable, such as attest services)
• Due Care and Competence
• Confidential Client Information
• Responsibilities to Colleagues, Employers, and the Public
When a CPA is serving in a tax capacity rather than an audit or attest role, particular attention is given to SSTS, which addresses quality and ethical standards for tax practice. Nevertheless, the fundamental principles of the AICPA Code of Professional Conduct still apply, ensuring that CPAs safeguard the public interest.
Below is a quick comparison of major topics covered by both Circular 230 and AICPA standards:
flowchart LR A(Circular 230) --> B(Practice Before the IRS) A --> C(Due Diligence, Competence, No Conflicts) A --> D(Various Prohibitions & Requirements) E(AICPA Code of Professional Conduct & SSTS) --> F(All Professional Activities) E --> G(Objectivity, Integrity, Due Care) E --> H(Confidential Client Info) B --> I(Authorized Representation) C --> I D --> I F --> J(High Professional Standards) G --> J H --> J
In this diagram:
• Circular 230 (A, B, C, D) focuses on authorized representation, due diligence, conflicts of interest, and additional prohibitions (e.g., improper use of contingent fees).
• AICPA Code of Professional Conduct & SSTS (E, F, G, H) encompasses all professional activities, emphasizing objectivity, integrity, due care, and confidentiality.
One of the most pervasive challenges in tax practice is managing conflicts of interest, which occur when a CPA’s obligations to one party conflict with those owed to another. For instance, a CPA might prepare the tax returns of two business partners going through a dissolution, or might represent both a corporation and certain shareholders. Under Circular 230 and the AICPA Code of Professional Conduct:
• CPAs must disclose any potential conflict of interest and obtain informed consent from all affected parties before proceeding with an engagement.
• Even with disclosure, certain conflicts are so profound they cannot be “cured” by obtaining consent.
• Proper documentation is critical. If a client consents to waive a conflict, maintain a written record of the waiver.
Suppose you are engaged to provide tax compliance services for a small family business, but you also do the personal tax returns for each family member. As the family business expands, disputes might emerge among siblings working in the company. A conflict arises if both the entity and the sibling personal returns have contradictory tax positions, or if certain family members want you to strategize in ways that adversely affect others. You must ensure that you can continue representing all parties without compromising any client’s interest. If such adversity is unavoidable, you may need to disengage from one (or more) parties.
• What if the exam question indicates that you discover a conflict in mid-engagement, such as discovering that your client’s business partner is also your audit client?
• What steps should a CPA take if the business partner’s interests materially diverge from your main client’s objectives?
The correct approach would generally involve immediate disclosure to both clients, obtaining asked-for consents, or potentially disengaging if the conflict is irreconcilable. This is central to maintaining objectivity and independence.
Both Circular 230 (§10.22) and AICPA Standards (principles of Due Care) require CPAs to exercise diligence when handling tax affairs. This includes verifying factual information, performing thorough research into tax positions, and documenting your rationale for specific recommendations.
A client invests in a complex partnership arrangement that offers large deductions. Before claiming these deductions on the client’s return, you must:
Failure to exercise due diligence exposes both you and your client to potential penalties, not to mention possible disciplinary actions under Circular 230.
Both AICPA professional standards and Circular 230 address the protection of confidential client information. According to the AICPA Code of Professional Conduct (ET §700 series):
• You cannot disclose client information without the client’s explicit consent, except in limited circumstances (e.g., in response to a valid court subpoena, a request by an authorized government agency, or an official peer review panel).
• You must also safeguard client data against unauthorized access, which now includes cybersecurity considerations (e.g., ensuring proper encryption for electronic records).
Circular 230 §10.20–§10.25 also imposes duties on the practitioner to provide certain information to the IRS upon lawful request, but that does not override the duty to maintain confidentiality in other scenarios. Failure to maintain confidentiality can lead to disciplinary measures by the Treasury and possibly lawsuits by the affected client.
• What if your close friend, who is not associated with your client, casually asks you about the details of a high-profile merger your client is undertaking? Are you allowed to confirm any details that are arguably “public knowledge”?
• Under the AICPA Code of Professional Conduct, the safe stance is to not disclose any information, even if you believe some aspects are public. You risk inadvertently releasing nonpublic insights that might harm your client.
The exam might test whether you understand your obligations to maintain confidentiality despite social or other professional pressures.
Below are some additional “what-if” scenarios that could appear on the exam, along with guidance on how to reason through them:
• Scenario A: You find out that a long-time client is misrepresenting major deductions to reduce taxable income. They have not provided receipts or proof of expenses. You learn from an informal conversation that some expenses might even be illegal payments.
• Scenario B: A corporate client requests you to file an extension that includes inaccurate estimated tax data. They plan to “fix it later.”
• Scenario C: Your firm wants to roll out a new marketing campaign that highlights “Expert IRS Representation, 100% Success Guaranteed!”
Below is a simple flowchart illustrating a recommended process for resolving ethical dilemmas under Circular 230 and AICPA standards:
flowchart TB A[Identify the Issue] --> B[Relevant Guidance: Circular 230 or AICPA Code] B --> C[Evaluate Potential Conflicts, Risks & Responsibilities] C --> D[Discuss with Client/Obtain Consents if Needed] D --> E[Document in Writing] E --> F[Decide to Proceed, Modify Scope, or Disengage]
Explanation of steps:
• Identify the issue. Is there a conflict of interest? An independence concern? A question about confidentiality or due diligence?
• Consult relevant professional standards (Circular 230, SSTS, AICPA Code of Professional Conduct, local laws).
• Evaluate all possible risks and responsibilities, including your duty to the client, public interest, and enforcement authorities.
• Talk with the client if needed. Obtain waivers or consents in writing—but only if permissible.
• Document your findings and decisions thoroughly.
• Either proceed ethically, adjust the engagement scope, or withdraw if you cannot reconcile the issues.
Pitfall: Overlooking small details in documentation or ignoring red flags.
Pitfall: Advising clients on uncertain tax positions without properly disclosing the level of uncertainty or potential consequences.
Pitfall: Accepting an engagement despite an unresolved conflict of interest.
Pitfall: Failing to keep up with emerging legislative updates and new ethical interpretations.
A CPA firm represents two business partners, Alice and Bob, who formed a partnership in real estate development. The firm also files the partnership return and personal returns for both partners. Over time, the partners have diverging opinions on how to manage the partnership, leading to a heated dispute about certain property losses.
• Bob suspects Alice wants to allocate more losses to herself to offset taxable gains on another personal venture.
• Alice claims this approach is justified by the actual financial contributions she made, so she requests the CPA to file returns that reflect a disproportionate share of the losses.
• Bob strongly believes this is incorrect and demands that you “fix” the K-1 allocations.
• Attempt to gain mutual consent for the resolution of the dispute.
• If Alice and Bob cannot see eye to eye, you may have to withdraw from preparing returns for one (or both) while ensuring each remains informed of the reasons and potential consequences.
This scenario underscores the typical complexities encountered in practice and on the CPA exam. Ethics is not always black and white; it calls for professional judgment guided by established standards.
• U.S. Treasury Circular 230: “Regulations Governing Practice before the Internal Revenue Service”
• AICPA Code of Professional Conduct (latest edition, accessible on the AICPA website)
• AICPA Statements on Standards for Tax Services (SSTS)
• IRS Publication 947: “Practice Before the IRS and Power of Attorney”
Expanding your knowledge of the above resources is invaluable for both exam preparation and a successful career in tax compliance and planning.
Ethical decision-making is the cornerstone of responsible CPA practice. Whether you are navigating a potential conflict of interest, exercising due diligence on a complex return, or protecting confidential client data, understanding the mandates of Circular 230 and AICPA Standards is essential. By applying consistent ethical reasoning, CPAs not only comply with regulations but also guard their reputation and protect the public trust.
In your exam preparation—and even more importantly, in real-life practice—always remember to:
By embracing these ethical principles, you sustain the integrity of the accounting profession and set an example of professional excellence.
