D550: Ethics for Accountants

A guide to WGU's D550, the Master of Science in Accounting course on professional conduct, ethical reasoning and auditor responsibilities.

Updated October 2026 · 5 min read

D550 Ethics for Accountants examines the standards of conduct that govern the accounting profession. It is in the first term of WGU's Master of Science in Accounting, Auditing Specialization.

WGU describes ethical principles in applying accounting standards, tax preparation and attest services, and explores ethical reasoning, professional skepticism and decision-making in corporate governance and moral dilemmas.

It discusses the AICPA Statements on Standards for Tax Services and the IMA Statement of Ethical Professional Practice. The hard part is moving from rules to reasoned judgment about a case.

Key Concepts Explained

A Framework for Ethical Decisions

Identify the facts, the stakeholders, the relevant professional standards and the options. Evaluate each option against the standards and choose, then explain why.

Example: A senior accountant is asked by a manager to delay recording an expense to hit a bonus target. The stakeholders include investors, the employer and the accountant. The relevant principles are integrity and objectivity. The reasoned action is to record the expense correctly, document the request and use the escalation route.

Professional Skepticism

This is a questioning mind and critical assessment of evidence. In practice it means not accepting explanations at face value when the facts do not fit.

Independence

Auditors must be independent in fact and in appearance. Analyze relationships that might impair objectivity, such as financial interests or non-audit services.

Typical Assignments and How to Approach Them

Your task instructions state the format. Work in this course typically involves:

Work typeWhat it testsHow to approach it
Ethical case analysisReasoning and code applicationCite the relevant provisions and justify the action
Governance and independence reviewUnderstanding oversightIdentify threats and safeguards
Legal liability discussionKnowledge of lawExplain duties, risks and defenses accurately

Writing a Strong D550 Answer

Cite the exact code section or standard that applies, then show how the facts engage it. Avoid generic statements about doing the right thing.

A Second Worked Example

Assessing an Independence Threat

Imagine an audit firm that also designs the client's accounting software. The question is whether this impairs independence.

Example: The firm would later audit the system it built, creating a self-review threat. The analysis identifies the threat, asks whether safeguards such as a separate team can reduce it to an acceptable level, and concludes that if they cannot, the firm should decline one of the engagements. It cites the relevant independence provisions of the professional code.

Self-Check Before You Submit

The scenario is illustrative.
