Explore core ethical obligations, mandatory return-signing protocols, confidentiality requirements, and avoidance of conflicts of interest for tax practitioners. Learn about Circular 230, real-world scenarios, and best practices to uphold professional integrity.
In the realm of taxation and regulation, tax practitioners hold positions of trust and responsibility. Clients expect them to navigate laws, regulations, and ethical guidelines to prepare and file accurate returns while safeguarding confidential information. Understanding the duties and restrictions outlined in federal regulations and professional standards not only ensures compliance but also fosters client confidence and personal accountability. This section delves into these key areas, focusing on signing returns, maintaining client confidentiality, and avoiding conflicts of interest.
Tax professionals—encompassing CPAs, Enrolled Agents (EAs), attorneys, and unlicensed preparers—must abide by an array of governing rules, chief among them Treasury Department Circular 230 (see also Chapter 3.1, “Treasury Department Circular 230”), state boards of accountancy regulations, and the AICPA Code of Professional Conduct. In this chapter, we examine essential duties, present relevant examples, discuss best practices, and highlight potential pitfalls with real-world scenarios.
Tax practitioners are entrusted with a wide range of responsibilities. While regulations and guidelines vary based on practitioner type and jurisdiction, certain universal themes emerge:
• Diligence in return preparation and submission.
• Proper signing of returns and claim forms.
• Adherence to confidentiality and privacy requirements.
• Disclosure when conflicts of interest arise.
• Ongoing compliance with ethical guidelines under Circular 230 and state laws.
Let us break down these critical points in greater detail.
One of the fundamental duties of tax practitioners is the proper signing of returns. Failure to comply can subject the practitioner to monetary and disciplinary sanctions. According to the IRS, any individual who prepares or substantially assists in preparing a tax return for compensation must sign the return as the paid preparer. Practitioners also need to include the Preparer Tax Identification Number (PTIN).
• Internal Revenue Code (IRC) §6695 imposes penalties for failing to sign.
• Treasury Department Circular 230, Subpart B, outlines a practitioner’s duties to provide accurate information and sign returns where applicable.
Imagine a small CPA firm where multiple staff accountants assist in preparing a complex business return. The staff accountant who has the primary responsibility for the return must sign it as the preparer and include their PTIN. If this staff accountant neglects to sign the return or fails to include the PTIN, the firm could face monetary penalties, and the accountant might be subject to further disciplinary action from the IRS.
• Always confirm that the person principally responsible for preparing the return signs and includes their PTIN.
• Maintain a system of quality control and internal review to prevent missing signatures or PTIN omissions.
• Document all client interactions, ensuring clarity regarding who is responsible for finalizing the return.
Safeguarding client information is paramount for tax practitioners. This obligation arises from multiple sources: federal statutes (e.g., IRC §7216 on tax return preparer confidentiality), state accountancy boards, and professional bodies such as the AICPA.
A CPA, hired to prepare an individual’s personal tax return, discovers the taxpayer owns various foreign investments requiring specialized forms (e.g., Form 8938 for Foreign Financial Assets). The CPA must handle these disclosures with the highest level of confidentiality, carefully ensuring no sensitive data is disclosed outside the course of compliance or to third parties without explicit client authorization. If the CPA used the client’s personal data to pitch unrelated financial products, this would violate confidentiality regulations and risk substantial penalties.
• Encrypt client data and store it on secure servers or locked files accessible only to authorized personnel.
• Obtain client consent in writing before sharing any tax information with third-party advisors (e.g., investment managers, lawyers).
• Implement comprehensive staff training on data privacy laws, focusing on best practices for communications (e.g., email encryption).
A conflict of interest arises when a tax practitioner’s loyalties become divided, potentially influencing their ability to represent a client fairly and objectively. The most common conflicts occur when a practitioner represents multiple parties with diverging interests or has a personal (financial or non-financial) interest that could impair independence.
Under Circular 230, practitioners must either refrain from representation or disclose the conflict to the affected clients, obtaining informed consent in writing. The practitioner should also evaluate whether they can competently and diligently represent all impacted clients. If not, withdrawal from the engagement may be necessary.
• Practitioner representing a partnership and, simultaneously, one of the partners personally. A dispute arises over allocation of partnership profits. If the practitioner continues to represent both entities, they risk appearing biased and could inadvertently breach duties of confidentiality.
• CPA working as both corporate accountant and personal financial planner for the CEO. Tax-saving strategies for the CEO might conflict with the corporation’s best interest and could cast doubt on the CPA’s independence.
• Screen clients carefully during intake and maintain rigorous documentation regarding potential overlapping interests.
• Obtain detailed conflict waivers and ensure that each client fully understands the implications of joint representation.
• If conflict escalates, consider referring one or all parties to another qualified practitioner to preserve integrity and objectivity.

Various regulations stipulate penalties and disciplinary measures for not adhering to required duties:
• Civil Penalties under IRC §6695 (Failure to sign returns or include PTIN, failure to furnish copy of return to taxpayer, etc.).
• Criminal Penalties under IRC §7206 or §7216 if confidentiality or privacy laws are intentionally violated.
• Suspension or disbarment from practice before the IRS under Circular 230 provisions.
• State Board of Accountancy Actions (e.g., license suspension, revocation) for violating state regulations.
• Missed Deadlines and Failure to Sign: One of the most obvious—but surprisingly frequent—oversight is failing to sign the return or missing critical deadlines for client filings.
• Misunderstanding the Scope of Confidentiality: Using client data for marketing or disclosing it to family members, even innocently, can result in a breach.
• Overextension of Services: Attempting to represent multiple parties with conflicting interests without obtaining written consent or adequately analyzing the conflict.
• Implement a tracking calendar or online practice management system that provides alerts for signing returns and filing due dates.
• Regularly review privacy policies with staff and update staff training modules on data security.
• Draft detailed engagement letters and conflict-of-interest documents, requiring signatures from all parties.
Consider a CPA firm that prepares tax returns for a married couple. Halfway through the year, the couple decides to divorce. Since the CPA firm has previously managed the couple’s joint interests, the separation raises immediate conflict-of-interest issues. The CPA must evaluate whether continuing to represent both parties is feasible without jeopardizing confidentiality or objectivity. If continuing representation of both is unrealistic, the CPA might need to either obtain conflict waivers (if both parties consent and the representation remains feasible) or withdraw from representing one or both parties entirely.
Key takeaways:
• Timely identification of a conflict is essential.
• Full disclosure to both parties ensures transparency.
• Written consent is required if representation continues.
• If representation cannot remain fully objective, disengagement is the safest route.
