Introduction: The Role of Auditors In Detecting Errors and Fraud
Auditors are responsible for forming an opinion on financial statements based on audit evidence, as defined by the SSA (Singapore Standard on Auditing) 700.
In other words, they obtain reasonable assurance that a business’s financial statements do not contain material misstatements. (2)
If you’re an accounting student like me or an industry professional, you should already know that audits are essential to businesses for legal compliance, stakeholder trust, and decision-making.
These are the benefits of getting your business independently audited:
- Legal Compliance: The Singapore Companies Act mandates that all private limited companies in Singapore must undergo an annual statutory audit. Only small companies, small groups, and dormant companies are exempted. (3)
- Stakeholder Trust: Audits are objective assessments that enhance your financial credibility to lenders and consumers. (4) It’s generally easier for audited companies to attract investments, employees, consumers, and partners. (5)
- Business Decision-Making: Accurate financial information verified by an auditor provides reliable information for informed business decision-making. (6)
Are auditors responsible for fraud? This is a question that often arises when discussing business failure. To clarify, auditors are not responsible for preventing fraud. However, they are essential for fraud detection and reporting. Independent audits are part of anti-fraud measures to protect the interests of stakeholders and investors.
In today’s post, I’ll be elaborating on the key signs of fraud and providing a list of what auditors should do if they suspect fraud. I’ll also explain the limitations of audits and clarify what auditors are not responsible for.
Signs of Fraud

Auditors are familiar with these signs of fraud when examining financial statements. (7) Let’s go through them:
- Shrinking Inventory: Actual inventory (the physical number of items in stock) may not match recorded figures due to accidental losses during transit and handling. This is normal and happens due to human error. However, significant inventory shrinkage can indicate fraud. Auditors may notice the balance sheet reflecting an unusual level of inventory shrinkage by comparing the present number of products in stock with previous records.
- Missing Documents: Missing critical documents may indicate attempts to conceal fraud. These documents include vehicle registration, chequebooks, and inventory reports.
- Duplicate Payments: Duplicate payments may be made to non-existent companies or vendors to defraud employers.
- Unrecorded Payments: Missing or understated payments may indicate ongoing fraud by internal employees.
- Excessively Adjusting Entries: Internal accounting teams may keep adjusting the account books to hide certain transactions.
- Employee Lifestyle Changes: Employees involved in fraud may suddenly start purchasing big-ticket items beyond what their lifestyle and current income level would allow.
Other fraud risk factors are caused by inadequate internal operations (8):
- No Independent Oversight: Employees can alter and approve financial records and transactions without external verification.
- No Mandatory Rotations or Vacations: The company does not regularly rotate or enforce mandatory vacations for employees in key financial roles.
As I’ll explain in the third section, internal operations also affect audit quality.
What Should An Auditor Do When Fraud Is Found?

According to the Statement of Auditing Practice, auditors must provide feedback on the audit to the audit committee or those charged with governance. This applies to all audits, whether fraud is suspected or not. (9)
If misstatements are identified and fraud is suspected, the auditor must:
1. Gather Evidence
Auditors who suspect a misstatement indicates fraud must gather evidence and maintain documentation for their case. SSA 240 (p9) states that auditors should evaluate whether this insight affects other aspects of the audit, like management representation accuracy. (10)
Since fraud is usually not an isolated occurrence, the auditor must also assess the reliability of management representation.
After gathering evidence, auditors must decide whether to escalate the matter to management, those charged with governance, or seek legal counsel.
2. Notify Management
According to the Statement of Auditing Practice, auditors who suspect fraud should notify the audit committee and management first. (9)
However, if the auditor suspects that the fraud involves:
- Management
- Key employees involved in internal controls or financial oversight
- Other employees, leading to material misstatements in financial statements
The auditor should report fraud to those charged with governance instead — the board and audit committee members. (9)
3. Inform Regulatory Authorities
The SSA 240 (Singapore Standards on Auditing) states that auditors should resolve matters concerning internal fraud suspicion through internal communications. This refers to management, the board and audit committee members.
However, auditors should inform regulatory authorities if the fraud concerns public interest or has significant financial implications. (10)
According to Section 207(9A) of the Singapore Companies Act, auditors of public companies must report serious fraud offences to the Ministry of Finance. Serious fraud offences involve property or amounts of at least $20,000. (9)
4. Seek Legal Advice
If the auditor doubts the integrity and honesty of those in management or those charged with governance (the board, audit committee), they should seek legal counsel. (10)
5. Assess Impact on Financial Statements
Auditors must assess if the company’s financial statements need amendments due to the misstatement. They may issue audit opinions requesting corrective action from management if misstatements are not corrected.
6. Withdraw From The Engagement If Necessary
This only happens under exceptional circumstances. SSA 240 (p10) states that the auditor may withdraw from the engagement if the misstatement affects the auditor’s ability to continue carrying out their duties effectively. (10)
What Auditors Are Not Responsible For
Auditors who suspect fraud should know what is within their scope of work. In this section, I’ll explain what auditors should not do when reporting fraud.
1. Identify Suspects
The auditor should not pass judgment on who is guilty, even if they suspect specific individuals. They are only responsible for identifying alleged fraud, not investigating who was responsible for it or what caused it. (11)
2. Identify Factors Causing Company Failure
Auditors may discover fraudulent activity that is significant enough to affect business sustainability. In some cases, fraud could contribute to business failure. However, auditors are not responsible for investigating what causes company failure.
3. Verifying Document Authenticity
Auditors carry out their work based on management representation, which includes financial statements and related documents. They are not responsible for verifying the authenticity of these documents, as management is accountable for ensuring that they are accurate. (12)
4. Rectifying Issues
Auditors aren’t responsible for refining or modifying their client’s financial management system, even if they know what needs to be changed. Instead, they should inform management and the audit committee of any issues and suggest improvements.
5. Analysing or Reconciling Accounts
Auditors are not responsible for analysing or reconciling a client’s accounts. This is the duty of the business’s accounting and finance departments. The management must make modifications and improvements based on the audit report’s observations.
6. Preventing Fraud and Error
According to the Statement of Auditing Practice (approved by the Council of the Institute of Singapore Chartered Accountants), auditors are not responsible for preventing fraud and error. (9) The SSA 240 (p4) states that responsibility for fraud prevention lies with the management and those charged with governance. (10)
Why Auditors Fail To Detect Fraud
It is an auditor’s duty to report fraud under the Companies Act. (207(9)) However, several factors can prevent them from detecting fraud:
- Collusion and Concealment: Complex fraudulent schemes are often deliberately concealed with layers of false supporting evidence. Several employees involved in fraud may collude to mislead auditors. Furthermore, management override makes management fraud harder to detect than employee fraud. (SSA 240, p5)(10)
- Tight Deadlines: Auditors operate on strict deadlines and may not have time to investigate financial operations extensively. This means that some well-concealed fraudulent schemes may go uncovered. (13)
- Reasonable, Not Absolute Assurance: The SSA 240 (p4) clarifies that auditors are only expected to provide reasonable, not absolute, assurance that a firm’s financial statements are free of material misstatements. Inevitably, some errors will not be flagged out. (10)(14)
- Poor Internal Controls: Weak internal controls could create unreliable financial data, as employees can independently modify, add, and remove records. Auditors rely on this information to conduct audits. Financial information altered to conceal fraud will prevent the auditor from detecting anomalies. (15)
Final Thoughts
Auditors play a crucial role in maintaining financial reporting integrity. While they are legally required to report fraud, audit limitations may prevent them from detecting it. By understanding their duties and limitations, auditors can better focus their efforts during audits to ensure accurate financial information.
