Conflicts of interest

A conflict of interest in public accounting exists when a service, relationship or interest could threaten objectivity or loyalty, and the AICPA Code calls for identifying, evaluating, and where needed disclosing it and getting consent.

Definition

A conflict of interest arises when a professional service, relationship or interest creates an adverse interest or self-interest threat to a member's integrity or objectivity. The AICPA Conflicts of Interest interpretation (ET 1.110.010) asks the member to identify the conflict, evaluate it using professional judgment and the view of a reasonable and informed third party, and consider disclosure and consent. Circular 230, section 10.29, applies to practice before the IRS. It bars representation involving a conflict unless the practitioner reasonably believes the work can be done competently and diligently, the law permits it, and each client gives informed consent confirmed in writing within 30 days. Copies of consents are kept for at least 36 months after the representation ends.

Why it matters in an audit or review

Conflicts can lead to damaged objectivity, litigation and discipline. They differ from independence, which is a separate set of rules for attest clients.

Example

Illustrative: a firm prepares tax returns for two business partners who are in a dispute over the sale price of their company. The firm identifies the conflict, concludes it cannot represent both competently, and declines one engagement.

Common mistakes

  • Treating a signed engagement letter as consent.
  • Ignoring conflicts that arise after the engagement begins.

Related terms

  • Objectivity and integrity
    Objectivity and integrity are two principles in the AICPA Code. Objectivity is impartiality and freedom from conflicts of interest. Integrity means being honest and candid, without subordinating judgment to others.
  • Independence
    Independence for an auditor means independence of mind and independence in appearance. It is required for audits and reviews, and under the AICPA Code it is judged using a conceptual framework.
  • Threats and safeguards
    Threats are circumstances that could compromise compliance with the AICPA Code, and safeguards are actions that reduce them to an acceptable level. If none works, the member declines or stops.
  • Confidentiality
    Confidentiality is the duty of a member not to disclose confidential client information without the client's consent, except in situations the AICPA Code allows, such as a subpoena or peer review.
