Introduction
For many business owners in Singapore, the term “audit” can sound intimidating. In reality, an audit — when done with proper preparation and guidance — is a structured, logical process aimed at verifying financial accuracy, ensuring compliance, and improving business governance.
In Singapore, certain companies are legally required under the Companies Act (Cap. 50) to undergo a statutory audit, while others may voluntarily choose to be audited for business credibility and stakeholder trust. Regardless of whether the audit is mandatory or voluntary, the process generally follows a systematic approach to ensure thoroughness and reliability.
In this article, we will break down the full audit process in Singapore, from the initial engagement to the issuance of the final audit report.
1. Determining the Need for an Audit
Before starting, it’s important to determine whether your company requires a statutory audit or whether you are opting for a voluntary audit.
Statutory Audit Requirement:
A Singapore-incorporated company must have its accounts audited unless it qualifies as a Small Company (meeting at least 2 of these criteria for the past two consecutive financial years):
-
Total annual revenue ≤ S$10 million
-
Total assets ≤ S$10 million
-
Number of employees ≤ 50
Voluntary Audit:
Many companies that qualify for audit exemption still engage auditors voluntarily to:
-
Build investor confidence
-
Secure bank loans
-
Strengthen internal controls
2. Selecting the Audit Firm
Choosing a reliable ACRA-registered public accounting firm is critical.
Key factors to consider:
-
Relevant industry experience
-
Clear communication and transparency
-
Timely delivery of reports
-
Ability to provide tailored recommendations
Example: Koh & Lim Audit PAC works with clients across industries such as construction, F&B, retail, manufacturing, and professional services.
3. Engagement Letter & Scope Definition
Once an audit firm is appointed, they will issue an engagement letter that outlines:
-
Scope of work
-
Responsibilities of the auditor and client
-
Timelines and reporting deadlines
-
Audit fees
This letter is the official agreement that governs the working relationship.
4. Planning the Audit
The planning stage is crucial because it sets the foundation for the entire process.
During this phase, the auditor will:
-
Understand the client’s business operations
-
Review prior years’ financial statements
-
Identify key risks and areas requiring more attention
-
Develop an audit plan and schedule
The aim is to focus audit resources on high-risk areas that could impact the financial statements.
5. Internal Control Review
Before testing numbers, auditors assess internal controls to understand how transactions are processed and safeguarded.
They will:
-
Evaluate accounting systems and processes
-
Check segregation of duties (to prevent fraud)
-
Assess approval procedures for expenses and purchases
If controls are found to be weak, auditors will adjust their approach to perform more detailed testing.
6. Gathering Audit Evidence
Auditors rely on audit evidence to form their opinion. This can include:
-
Invoices and receipts
-
Bank statements and reconciliations
-
Inventory count sheets
-
Contracts and agreements
-
Payroll records
Evidence must be sufficient and appropriate — enough to support conclusions and relevant to the assertions being tested.
7. Substantive Testing
This is where the auditor tests the numbers. Common procedures include:
-
Analytical Review: Comparing current year figures with prior years and industry averages.
-
Detailed Testing: Checking samples of transactions to confirm accuracy.
-
Confirmations: Contacting banks, customers, and suppliers to verify balances.
-
Inventory Observation: Physically inspecting stock counts.
The goal is to detect any material misstatements.
8. Compliance Checks
Auditors also ensure the company complies with:
-
Singapore Financial Reporting Standards (SFRS)
-
Companies Act (Cap. 50) requirements
-
Tax regulations by IRAS
-
Industry-specific laws (if applicable)
Failure to comply can result in penalties or reputational damage.
9. Identifying Issues & Drafting Findings
If discrepancies are found, auditors will:
-
Document them in a management letter
-
Categorise them by severity (material vs. non-material)
-
Discuss them with management before finalising the audit report
This gives the company a chance to clarify or provide additional evidence.
10. Management Representation Letter
Before the final report is issued, auditors request a management representation letter confirming:
-
All relevant information has been provided
-
Financial statements are accurate and complete
-
No undisclosed liabilities or significant events exist
This serves as an additional safeguard for the auditor.
11. Issuing the Audit Report
The audit report provides the auditor’s opinion on whether the financial statements give a “true and fair view” in accordance with SFRS.
Types of audit opinions:
-
Unqualified Opinion (Clean Report) – Financial statements are accurate and comply with standards.
-
Qualified Opinion – Except for certain issues, the financial statements are fairly presented.
-
Adverse Opinion – Financial statements are materially misstated.
-
Disclaimer of Opinion – Auditor could not obtain sufficient evidence to form an opinion.
12. Post-Audit Recommendations
A good audit firm doesn’t stop at issuing the report. They provide practical recommendations to:
-
Strengthen internal controls
-
Improve accounting processes
-
Reduce compliance risks
13. Key Timelines for Singapore Audits
-
Within 6 months after financial year-end – Hold AGM (unless exempted).
-
Within 7 months after financial year-end – File annual returns with ACRA.
-
Audit must be completed in time to meet these statutory deadlines.
14. Tips for a Smooth Audit
-
Keep records organised throughout the year.
-
Respond promptly to auditor requests.
-
Perform internal reviews before the audit starts.
-
Engage an auditor early to avoid last-minute rush.
