The role of a tax professional is one of significant responsibility and trust. Tax professionals act as intermediaries between taxpayers and the complex tax system, assisting with compliance, planning, and representation. This privileged position demands adherence to high ethical standards and a thorough understanding of legal duties. Failure to uphold these principles can lead to severe consequences for both the professional and their clients. This chapter will explore the fundamental ethical principles and legal duties of tax professionals, with a particular focus on the regulations outlined in Treasury Department Circular No. 230. 

Fundamental Ethical Principles

While specific regulations like Circular 230 provide detailed guidance, several overarching ethical principles form the foundation of responsible tax practice:

• Integrity: Tax professionals must be honest, candid, and act with integrity in all professional and business relationships. This includes being truthful in their dealings with clients, the IRS, and other parties.
• Objectivity: Tax professionals should strive to be impartial and avoid conflicts of interest. Their professional judgment should not be compromised by bias or undue influence.
• Competence: Tax professionals have a duty to maintain professional knowledge and skill at a level required to ensure that clients receive competent professional services. This includes staying updated on changes in tax laws and regulations. 
• Confidentiality: Tax professionals are entrusted with sensitive financial information about their clients. They have a fundamental ethical duty to maintain the confidentiality of this information and should not disclose it without proper consent or legal authority. This is also legally protected under statutes like IRC § 7216.
• Due Care: Tax professionals must exercise due professional care in the performance of their services. This includes being diligent, thorough, and acting in good faith when preparing tax returns, providing advice, and representing clients.  

Legal Duties of Tax Professionals

Beyond ethical principles, tax professionals are subject to various legal duties:

• Compliance with Tax Laws: The primary legal duty is to comply with all applicable federal, state, and local tax laws and regulations. This includes accurately preparing and filing tax returns on behalf of clients and providing advice that is consistent with the law. 
• Fiduciary Duty (in some contexts): Depending on the nature of the relationship and the services provided, a tax professional may owe a fiduciary duty to their client. This duty requires them to act in the client’s best interest and with the utmost good faith.
• Avoiding Conflicts of Interest: Tax professionals have a legal duty to avoid situations where their personal interests or the interests of other clients could compromise their ability to act in the best interest of a particular client.   
• Maintaining Records: Tax professionals may have a legal obligation to maintain certain records related to the services they provide to clients.  
• Due Diligence: As mentioned in the ethical principles, due diligence is also a legal requirement, particularly when preparing or signing tax returns and providing advice.

Regulations Governing Practice Before the Internal Revenue Service- Circular 230

Treasury Department Circular No. 230 (31 CFR Part 10) provides regulations governing the practice of attorneys, certified public accountants, enrolled agents, enrolled retirement plan agents, enrolled actuaries, and appraisers before the Internal Revenue Service. It sets forth the duties and restrictions applicable to these practitioners and outlines the sanctions for violating these regulations.  

Circular 230 aims to protect the integrity of the tax system by establishing standards of conduct for those who represent taxpayers before the IRS. It covers a wide range of activities, including preparing and filing documents, corresponding and communicating with the IRS, rendering written advice on tax matters, and representing clients in audits, appeals, and other proceedings.

Key Subparts and Sections of Circular 230:

Common Ethical Dilemmas in Practice

Tax practitioners frequently encounter situations where competing duties—to the client, to the tax system, and to professional standards—create challenging ethical dilemmas. These situations test a practitioner’s integrity, objectivity, and commitment to compliance. Understanding how to identify and resolve these dilemmas using authoritative guidance, such as IRS Circular 230 and the AICPA Code of Professional Conduct, is crucial for maintaining public trust and a reputable practice. The following section explores several common ethical scenarios faced by tax professionals and outlines how established standards guide appropriate responses.

Aggressive Tax Positions

• Dilemma: Clients may pressure practitioners to take tax return positions that are overly aggressive or lack sufficient legal justification (e.g., failing to meet the “substantial authority” standard for undisclosed positions). This directly challenges the practitioner’s integrity and their dual duty to both the client and the tax system.
• Standards & Action: Professional standards (like Circular 230 §10.34 and IRC §6694 regarding preparer penalties) mandate that positions meet minimum thresholds of legal support. Practitioners must advise clients of the requirements and associated risks (like penalties) and must refuse to sign any return containing a position that fails to meet the minimum standard they are comfortable with and that is required by law or regulation.

Discovery of Prior Errors

• Dilemma: A practitioner discovers a significant error on a client’s previously filed tax return (whether prepared by them or another preparer). This creates an immediate conflict between the strict duty of client confidentiality and the professional responsibility to address known errors.
• Standards & Action: While the practitioner cannot inform the IRS without client permission due to confidentiality, standards like Circular 230 §10.21 and AICPA SSTS No. 6 require them to promptly inform the client of the error’s nature and potential consequences (tax, interest, penalties). They must advise the client on how to correct it (e.g., filing an amended return) and cannot participate in perpetuating the error on future returns. If the client refuses to correct a significant error, the practitioner must consider withdrawing from the engagement.

Suspicious Client Information

• Dilemma: A client provides information that appears inconsistent, incomplete, or suspicious, raising doubts about its accuracy or completeness. While practitioners generally rely on client data, blind reliance can lead to participation in filing inaccurate returns.
• Standards & Action: The duty of due diligence (Circular 230 §10.22, AICPA SSTS No. 3) requires professional skepticism. Practitioners must make reasonable inquiries to resolve inconsistencies or obtain missing information. If the client is unwilling or unable to provide satisfactory clarification or documentation, the practitioner may be unable to prepare an accurate return and should decline the engagement.

Conflicts of Interest

• Dilemma: Situations arise where representing one client may be directly adverse to another client, or where the practitioner’s own interests conflict with a client’s (e.g., representing both spouses in a divorce, buyer and seller in a transaction, or partners with opposing goals).
• Standards & Action: Such conflicts impair the practitioner’s objectivity and loyalty. Standards like Circular 230 §10.29 and the AICPA Code require identifying these conflicts. Representation in a conflict situation is generally prohibited unless the practitioner reasonably believes they can provide competent and diligent service to each affected client, the representation isn’t legally barred, and each affected client gives informed consent, confirmed in writing. If these conditions aren’t met, the practitioner must decline or withdraw.

Confidentiality Breaches / Records Issues:

• Dilemma: Facing requests or pressure to improperly disclose confidential client tax information or failing to handle client records appropriately. Misusing client data or causing unreasonable delays in returning client records violates core professional tenets.
• Standards & Action: Strict confidentiality rules (especially IRC §7216, which carries potential criminal penalties) protect tax return information. Disclosure is only permissible under specific legal exceptions or with explicit, compliant client consent. Separately, practitioners must promptly return client-provided records upon request to allow the client to comply with their tax obligations (Circular 230 §10.28).
