Accounting Ethics and Professional Standards: What Every Accountant Must Know

Why Ethics Matters More in Accounting Than in Most Professions

Accountants occupy a position of unique trust in the financial system. Investors rely on audited financial statements to make capital allocation decisions. Creditors rely on them to evaluate creditworthiness. Regulators rely on them to assess compliance. Employees, customers, and communities rely on the financial information produced by accountants to understand the health of organisations that affect their lives.

When accountants fail to uphold ethical standards — through negligence, self-interest, or deliberate dishonesty — the consequences can be devastating. Enron, WorldCom, Lehman Brothers, and dozens of other financial scandals resulted in massive losses for investors, employees losing their retirement savings, and systemic damage to trust in financial markets. In each case, accountants and auditors failed to meet their professional obligations.

The AICPA Code of Professional Conduct

For CPAs in the United States, the primary ethical framework is the AICPA Code of Professional Conduct. The Code establishes principles that govern the conduct of all CPAs and rules that are mandatory. The fundamental principles are: responsibilities (exercising sensitive professional and moral judgment in all activities), the public interest (accepting the obligation to act in a way that serves the public interest), integrity (maintaining and broadening public confidence), objectivity and independence (maintaining intellectual honesty and, for attest services, independence), due care (observing the profession's technical and ethical standards), and scope and nature of services (determining the scope of services consistent with the Code).

Independence: The Cornerstone of Auditing Ethics

For accountants performing audit, review, and other attest services, independence is the most critical ethical requirement. Independence means being free from conflicts of interest — both in fact (actual independence) and in appearance (no relationship that a reasonable observer would believe impairs independence).

Specific independence rules prohibit auditors from having financial interests in their audit clients, serving on the boards of audit clients, providing certain non-audit services to audit clients concurrently with the audit, and having certain personal relationships with key client personnel. The Sarbanes-Oxley Act of 2002 (SOX) significantly tightened independence requirements for auditors of public companies after the Enron scandal.

Circular 230: Ethics for Tax Practitioners

For accountants who practice before the Internal Revenue Service — advising clients on tax matters, preparing tax returns, representing clients in audits — the primary ethical framework is Treasury Department Circular 230. Circular 230 governs who may practice before the IRS, what standards of competence and conduct practitioners must meet, and what sanctions apply for violations.

Key provisions include the duty to provide competent representation, the prohibition on unreasonably charging fees, the requirement to submit accurate information to the IRS, and the rules governing written tax advice. The CPA exam tests Circular 230 provisions on the REG section, and understanding them is also practically essential for any accountant who works in tax practice.

The AICPA Statements on Standards for Tax Services

The Statements on Standards for Tax Services (SSTSs) provide ethical guidance for CPAs in tax practice, complementing Circular 230 with AICPA-specific standards. The SSTSs address tax return positions (the standard required to take a position on a return), signing returns, advising clients on positions, responding to client errors, and using estimates.

A key principle in the SSTSs is the treatment of client errors. If a CPA discovers that a client has made a material error on a previously filed return, the CPA must inform the client promptly. However, the CPA cannot simply correct the error without the client's knowledge — the decision to file an amended return belongs to the client. If the client refuses to correct a material error and the CPA is retained for subsequent years, the CPA must consider whether continued representation is appropriate.

Fraud and the Accountant's Responsibility

Accountants have specific responsibilities related to fraud under auditing standards. AU-C 240 requires auditors to plan and perform audit procedures to obtain reasonable assurance about whether the financial statements are free from material misstatement due to fraud. Auditors must assess fraud risk factors, including incentive and pressure, opportunity, and rationalisation — the "fraud triangle."

Management fraud — where company executives deliberately misrepresent financial results — is the most difficult type for auditors to detect because management controls the information the auditor uses. Auditors address this risk through professional scepticism, unpredictable audit procedures, and attention to management override of controls.
