4.2 – Ethics and Legal Duties in Tax Practice
A tax professional occupies a position of real trust, standing between an individual taxpayer and a complex, high-stakes system of federal law. That position carries both ethical obligations, which govern how a preparer should behave as a matter of professional character, and legal duties, which govern how a preparer must behave as a matter of enforceable rule. The single most important source of those legal duties is Treasury Department Circular 230, the regulation that governs anyone who practices before the IRS. Understanding where ethics ends and enforceable regulation begins is essential for anyone entering tax practice.
Core Ethical Principles for Tax Professionals
Several principles recur across every code of conduct written for tax practitioners. Integrity requires honesty and candor in every dealing with a client, the IRS, and other parties, without shading the truth to make an engagement easier. Objectivity requires the practitioner to keep personal or firm interests from clouding professional judgment, which is why conflicts of interest are treated so seriously. Competence requires staying current with a body of law that changes constantly, since advice based on outdated rules can harm a client even when it is given in good faith.
Confidentiality requires protecting a client’s financial information, a duty that is not just an ethical norm but is also backed by law under IRC Section 7216, which can carry criminal penalties for improper disclosure of return information. Due care requires the diligence and thoroughness to get the technical work right, not just the intention to do so. Together these principles describe the character a tax practice is supposed to have, even before any specific regulation is consulted.
Legal Duties Beyond Ethics
Beyond these general principles, tax professionals carry duties that are directly enforceable. The most basic is compliance with tax law itself: preparing and filing accurate returns and giving advice consistent with the law as it actually stands. In some client relationships a preparer also owes a fiduciary duty, meaning they must act in the client’s best interest with the utmost good faith, a higher standard than an ordinary arm’s-length business relationship.
Practitioners also have a duty to avoid situations where one client’s interests conflict with another’s, or with the practitioner’s own interests, and a duty to maintain adequate records of the services provided. Due diligence appears again here as a legal, not just ethical, requirement, particularly when a preparer signs a return or gives written advice that a client will rely on.
Circular 230: Purpose and Structure
Circular 230, found at 31 CFR Part 10, is the regulation that governs attorneys, CPAs, enrolled agents, enrolled retirement plan agents, enrolled actuaries, and appraisers who practice before the IRS. Its purpose is to protect the integrity of the tax system by setting minimum standards of conduct for anyone representing a taxpayer, whether that representation involves preparing documents, communicating with the IRS, giving written tax advice, or handling an audit or appeal.
The regulation is organized into subparts. Subpart A defines who is authorized to practice before the IRS and the requirements for enrollment. Subpart B, the largest and most consequential part, sets out the specific duties and restrictions practitioners must follow. Subpart C describes the sanctions the IRS can impose for violations, and Subpart D lays out the procedure for disciplinary proceedings against a practitioner accused of violating the rules.
Key Duties Under Circular 230, Subpart B
Several sections of Subpart B come up constantly in practice. Section 10.22 requires diligence as to accuracy: a practitioner must exercise due diligence in preparing returns and other documents, not simply pass along whatever a client provides. Section 10.21 requires promptly furnishing information the IRS has lawfully requested, and Section 10.23 requires not unreasonably delaying a matter pending before the IRS.
Section 10.28 requires a practitioner to promptly return a client’s records so the client can meet their own tax obligations, even if a fee dispute is unresolved. Section 10.29 requires declining or withdrawing from an engagement where a genuine conflict of interest exists, unless each affected client gives informed, written consent. Section 10.34 sets the substantive standard for advising on and preparing returns, generally requiring a reasonable basis for any position taken, and Section 10.37 sets detailed requirements for written advice, including considering all the relevant facts and reaching a conclusion that the law actually supports.
IRC Preparer Penalties
Separate from Circular 230’s own enforcement, the Internal Revenue Code imposes direct monetary penalties on return preparers. IRC Section 6694 penalizes a preparer when a return position produces an understatement of tax: a lower-tier penalty applies where the position lacked a reasonable basis, or, for a position requiring disclosure, lacked substantial authority, while a materially higher-tier penalty applies where the preparer’s conduct in taking the position was willful or reckless.
IRC Section 6695 imposes smaller, more procedural penalties for failures such as not signing a return the preparer completed, not furnishing a copy to the taxpayer, or not retaining the records the law requires a preparer to keep. These IRC penalties are independent of Circular 230 sanctions and can apply on top of them, so a single serious lapse can expose a practitioner to a monetary penalty from the IRS and separate disciplinary action under Circular 230.
Sanctions for Violating Circular 230
Subpart C of Circular 230 authorizes several levels of sanction depending on the severity of the violation. Censure is a formal public reprimand that does not remove the practitioner’s ability to practice. Suspension removes that ability for a defined period, and disbarment removes it indefinitely, effectively ending the practitioner’s ability to represent clients before the IRS.
Beyond the sanctions written into Circular 230 itself, a serious violation can trigger consequences from other authorities entirely: state licensing boards can revoke a CPA license or bar admission for an attorney, intentional misconduct can lead to criminal charges, and a client harmed by negligent or dishonest advice can bring a civil lawsuit. The reputational cost of a public disciplinary action is often the most lasting consequence, since it affects a practitioner’s ability to attract and keep clients long after any formal sanction has ended.
Common Ethical Dilemmas and How Standards Resolve Them
Certain situations recur often enough in practice that professional standards address them directly. When a client pressures a preparer to take an aggressive position that lacks adequate legal support, Circular 230 Section 10.34 and IRC Section 6694 both require the position to clear a minimum threshold before it can be taken, and the preparer must be willing to decline to sign a return that does not meet it. When a preparer discovers a significant error on a client’s previously filed return, confidentiality prevents notifying the IRS without permission, but Section 10.21 still requires promptly telling the client about the error and its consequences and refusing to carry the same error forward on future returns.
When client-provided information looks incomplete or inconsistent, the due diligence duty in Section 10.22 requires making reasonable inquiries rather than accepting the numbers at face value, and declining the engagement if the client cannot resolve the inconsistency. When representing one client would work against another client’s interests, Section 10.29 generally requires declining or withdrawing unless every affected client gives informed written consent and the practitioner reasonably believes competent service can still be provided to each. In every one of these situations, the resolution comes from applying a known, written standard rather than from the practitioner’s personal judgment alone, which is exactly what gives Circular 230 its force.
Quick revision summary

- Subpart B sections such as 10.21, 10.22, 10.28, 10.29, 10.34, and 10.37 set the specific duties practitioners must follow.
- IRC Sections 6694 and 6695 impose separate monetary penalties on preparers, independent of any Circular 230 sanction.
- Violations can lead to censure, suspension, or disbarment under Circular 230, plus possible license revocation, criminal charges, or civil liability.
