Ethical Threats and Safeguards for Auditors in ACCA Audit and Assurance

Updated 11 October 2026 · Fact-checked

Auditors must follow five fundamental principles: integrity, objectivity, professional competence and due care, confidentiality and professional behaviour. Five threats can breach them: self-interest, self-review, advocacy, familiarity and intimidation. You identify the threat, judge its significance, then apply safeguards. If none work, you decline or withdraw.

Understand Ethical Threats and Safeguards for Auditors

An audit is only valuable if users trust the opinion. That trust depends on the auditor being honest, competent and independent. Ethics rules exist to protect that trust.

The IESBA Code sets out five fundamental principles:

Integrity: be straightforward and honest.
Objectivity: do not let bias, conflict of interest or the influence of others override your judgement.
Professional competence and due care: keep your knowledge up to date and act diligently in line with standards.
Confidentiality: do not disclose or use client information without proper authority, unless there is a legal or professional right or duty to disclose.
Professional behaviour: comply with law and avoid conduct that discredits the profession.

The Code uses a conceptual framework. You do not memorise a rule for every case. You identify threats to the principles, evaluate them, and address them. Threats come in five types:

Self-interest: you have a financial or other interest that could influence judgement. Example: owning shares in the client, or depending on one client for a large share of fees.
Self-review: you review your own work or that of your firm. Example: the firm prepares the financial statements and then audits them.
Advocacy: you promote the client's position so that objectivity is compromised. Example: acting as the client's lawyer in a dispute, or helping it sell shares.
Familiarity: a close relationship makes you too sympathetic to the client. Example: the same engagement partner for many years, or a close family member as the client's finance director.
Intimidation: you are deterred from acting objectively by actual or perceived pressure. Example: the client threatens to remove you if you do not accept its accounting treatment.

If a threat is not at an acceptable level, you must address it. You can eliminate the circumstances, apply safeguards, or decline or end the engagement. Typical safeguards are using a separate team, an independent review by a partner not on the audit (an engagement quality review), rotating senior staff, and disclosing matters to those charged with governance. For listed or public interest entities, rules are stricter. For example, some non-audit services are prohibited and rotation is expected.

Key rules to remember

Five fundamental principles: Integrity, Objectivity, Professional competence and due care, Confidentiality, Professional behaviour; Memory aid: I-O-P-C-P. Name them accurately in answers.
Five threats: Self-interest, Self-review, Advocacy, Familiarity, Intimidation; Label each issue in a scenario with one threat. Some issues give more than one.
Threat response: Identify → Evaluate significance → Eliminate or apply safeguards → Decline or withdraw if unresolved; This is the conceptual framework in four moves.
Common safeguard types: Separate teams, independent review, rotation, disclosure to those charged with governance, firm-wide policies and training; Match the safeguard to the threat. Do not list generic ones.

How to solve Ethical Threats and Safeguards for Auditors questions

Use the same sequence for any ethics scenario, whether it is a Section A OT case or a Section B written requirement.

1Read the scenario and underline each fact that could affect independence or another principle, such as a fee, shareholding, relationship, service or pressure.
2For each fact, name the threat type (self-interest, self-review, advocacy, familiarity or intimidation) and the principle at risk.
3Explain why in one sentence, linking the specific fact to the threat. Do not just state the label.
4Judge significance. Consider size, closeness and whether the client is listed or a public interest entity.
5Give a safeguard that fits that threat, for example a separate team for self-review or rotation for familiarity.
6State the outcome: continue with safeguards, or decline or withdraw if the threat cannot be reduced to an acceptable level.
7If asked, mention communication with those charged with governance and documentation of your conclusion.

Quickest way: Fact – Threat – Safeguard

When to use it: Use when time is short and the question asks you to identify threats and recommend actions, especially in Section B.

Write three columns or lines per issue: fact, threat, safeguard.
Use the question's mark count to decide how many issues to cover. Aim for one clear point per mark.
Keep each point to one sentence of fact, the threat name, and one targeted safeguard.
Finish with a one-line conclusion on whether the firm can accept or continue the engagement.

Common mistakes in Ethical Threats and Safeguards for Auditors

Only listing the names of the five threats without applying them to the scenario.
Students recall the definitions but do not link them to the facts given.
Fix: Quote the specific fact and explain how it creates the threat in one sentence.
Mixing up self-review and self-interest.
Both involve the firm benefiting or being involved in the client's affairs.
Fix: Ask whether you would be checking your own firm's work (self-review) or whether you gain financially or personally (self-interest).
Suggesting generic safeguards such as 'be more careful'.
Students run out of time or ideas.
Fix: Choose concrete safeguards: separate team, independent partner review, rotating the partner, or disclosure to those charged with governance.
Always saying the firm must resign.
Students think any threat is a breach.
Fix: Threats can often be reduced with safeguards. Only decline or withdraw when safeguards cannot reduce the threat to an acceptable level.
Forgetting that confidentiality has exceptions.
Students treat it as an absolute duty.
Fix: State that disclosure is allowed or required where law permits or requires it, or there is a professional right or duty to disclose, and with client consent.
Ignoring whether the client is listed or a public interest entity.
The detail is easy to miss in a long scenario.
Fix: Check the client type first. Threats are viewed as more significant and some services are restricted for such entities.

Worked examples

Example 1

Your audit firm has audited Delta Ltd for eight years. The firm also prepared Delta's financial statements this year, and Delta's finance director is the sister of the audit engagement partner. Identify the threats and suggest safeguards.

Show the solution

Fact 1: the firm prepared the financial statements it now audits. This is a self-review threat, because the firm would be reviewing its own work. It risks objectivity.
Safeguard for Fact 1: use separate staff for accounting and audit, with an independent partner review of the audit work. Alternatively, stop providing the accounting service.
Fact 2: the finance director is the engagement partner's sister. This is a familiarity threat, and a close family relationship is a significant one.
Safeguard for Fact 2: replace the engagement partner with another partner who has no relationship, and review the work done to date.
Fact 3: eight years of service may add to familiarity. Consider rotating senior team members.
Conclusion: the firm can continue only if the safeguards are applied. If the accounting service and relationship cannot be separated, the firm should not accept or continue the audit.

Answer: Self-review (firm prepared the accounts) and familiarity (partner's sister is finance director, long tenure). Safeguards: separate teams and independent review, replace the partner, and rotate staff. If these cannot be applied, decline or withdraw.

Example 2

Echo Ltd is an audit client. It tells your firm that unless you accept its treatment of a disputed revenue item, it will put the audit out to tender. Echo also pays your firm a large share of its total fees. Explain the threats and what the firm should do.

Show the solution

The tender threat is an intimidation threat. The client is pressuring the firm to accept a treatment, which could stop the firm acting objectively.
The heavy dependence on Echo's fees is a self-interest threat. Losing the client would hurt the firm financially, which may influence judgement.
Safeguards for intimidation: discuss the matter with those charged with governance, and have an independent partner review the revenue judgement. Document the discussion.
Safeguards for self-interest: if fee dependence is high, the firm should consider an independent review of the work and disclose the fee dependence to those charged with governance. If the dependence is too high, the firm should consider declining the client.
The firm must not give in on the revenue treatment. Integrity and objectivity override commercial pressure. If the item is material and misstated, the audit opinion must be modified.

Answer: Intimidation (tender threat) and self-interest (fee dependence). Use independent review, talk to those charged with governance, and keep objectivity on the revenue issue. Withdraw if the threats cannot be reduced to an acceptable level.

Exam tips

Label every issue with one specific threat name. Examiners award marks for the label and the link to the fact.
Always pair a threat with a matching safeguard. One mark is often for the threat and one for the response.
Check whether the client is listed or a public interest entity before deciding how serious a threat is.
In objective questions, read carefully for words like 'review own work' (self-review) or 'pressure' (intimidation). The wording usually points to the right type.
End written answers with a clear conclusion: accept or continue with safeguards, or decline or withdraw.
