  • Quality Management (December 15, 2025): Align the Code with global standards, moving from "quality control" to a "system of quality management."

Applicability of AICPA Code of Professional Conduct?

The AICPA Code of Professional Conduct applies to all members of the American Institute of Certified Public Accountants (AICPA), regardless of their status of work in public practice, industry, government, or education. Even if you are not a member of AICPA, most states have adopted and enforced it for licensed CPAs.

Type of Members?

The definition of the term “member” is based on the member's role.

  1. Members in Public Practice: Includes auditors and consultants providing services to clients.
  2. Members in Business: Covers CPAs in industry, government, or education.
  3. Other Members: Applies to CPAs who are retired, unemployed, or between jobs, who maintain their AICPA membership but do not currently practice accounting.

The Six Core Principles of Professional Conduct

The six core foundational principles that every CPA should understand and internalize for decision-making. These principles form the ethical foundation of the profession. When studying your CPA CPE credits, remember that the principles provide the framework from which all rules are derived.

The Six Core Principles of Professional Conduct

1. Responsibilities

As professionals, CPAs must exercise sensitive professional and moral judgment in all activities. The accounting profession plays an essential role in society, and members bear responsibilities not only to their clients and employers but also to the public at large. 

CPAs are expected to cooperate with one another to improve the profession, maintain public confidence, and uphold self-governance standards.

2. The Public Interest

CPAs must act in a way that serves the public interest, honors public trust, and demonstrates a commitment to professionalism. The public—including clients, investors, governments, employers, and the broader financial community—relies on CPAs for objectivity and integrity. 

This principle acknowledges that when CPAs fulfill their responsibility to the public, the interests of individual clients and employers are best served as a result.

3. Integrity

To maintain and broaden public confidence, CPAs must perform all professional responsibilities with the highest sense of integrity. Integrity is fundamental to professional recognition and the source from which public trust derives. It requires honesty and candor within the bounds of client confidentiality. 

Importantly, integrity can accommodate inadvertent errors and honest differences of opinion, but it cannot accommodate deceit or subordination of principle.

4. Objectivity and Independence and Independence

CPAs must maintain objectivity and be free of conflicts of interest. For members in public practice, this principle extends to requiring independence both in fact and in appearance when providing auditing and other attestation services. 

Objectivity is a state of mind—a quality that lends value to professional services and is a distinguishing feature of the accounting profession.

5. Due Care

CPAs must observe the profession's technical and ethical standards, strive continually to improve competence and service quality, and discharge professional responsibility to the best of their ability. Due care requires competence derived from a synthesis of education and experience. 

It emphasizes that members are individually responsible for maintaining their competence throughout their professional lives.

6. Scope and Nature of Services

Members in public practice must observe all principles of the code when determining the scope and nature of services to be provided. This principle prevents conflicts of interest, ensures competence, and maintains the integrity of the services delivered. 

Members must assess whether providing certain services to a client could create conflicts or compromise their objectivity.

Interpretations and Guidance

The code goes beyond stating rules; it provides interpretations that explain scope, application, and context. These interpretations are developed through a formal process that includes exposure to the membership, state societies, and regulatory bodies. A member who departs from these interpretations carries the burden of justifying that departure in any disciplinary hearing.

Additionally, the AICPA issues nonauthoritative guidance, such as the Conceptual Framework Toolkit and Ethics Questions & Answers, to help members navigate complex scenarios. While not binding, these resources provide valuable context for understanding how principles translate into practice.

Note: When you encounter a scenario in CPE materials, your first step should be to identify which definitions apply. The definitions often determine whether a rule has been violated. Spend time memorizing the key definitions—they're the building blocks of ethical analysis.

Practical Compliance Practices for Modern CPAs

  • Build a Compliance Culture in Your Firm
  • Document Your Ethical Analysis
  • Consult External Resources When Uncertain
  • Address Breaches Promptly and Thoughtfully
  • Maintain Confidentiality While Complying with Law

Real-World Application: Imagine you discover a client has engaged in tax fraud. The code requires you to maintain confidentiality, but federal law may require reporting under certain circumstances. Rather than making this determination on your own, consult your state bar association, a legal advisor, or the AICPA ethics team. Documenting your consultation process protects you and demonstrates a good faith effort to comply.

Conclusion

The AICPA Code of Professional Conduct is more than a set of regulatory requirements—it's your professional compass. It guides you toward decisions that protect the public, preserve client relationships, and maintain the profession's integrity.

FAQs

The code itself acknowledges SEC, PCAOB, GAO, and DOL. Regulatory bodies are free to impose requirements that are more restrictive than the code and members must comply. 

Violations may lead to disciplinary actions, penalties, suspension of membership, or state board investigations.  

Many state boards require ethics-focused CPE as part of CPA license renewal requirements.

No. Each state board sets its own ethics for CPE rules, credit hours, and renewal requirements. Know your State Specific CPE Requirement.

International firms that are AICPA members or serve U.S. clients may still need to follow the code.
