The audit certification process in Singapore involves a structured sequence of steps from organising financial records and appointing a licensed auditor to conducting fieldwork, reviewing findings, and issuing a signed audit report. For most companies, the process takes four to eight weeks depending on the complexity of financials and the completeness of documentation prepared by the business.
If you're an SME owner or part of an accounting team going through this for the first time, the process can feel opaque. This guide breaks it down clearly, step by step, so you know exactly what to expect and how to prepare at each stage.
Who Needs Audit Certification in Singapore?
Not every company in Singapore is required to undergo a statutory audit. Under the Companies Act, a company qualifies as a "small company" and is exempt from audit if it meets at least two of the following three criteria for the past two financial years:
- - Annual revenue of not more than S$10 million
- - Total assets of not more than S$10 million
- - No more than 50 employees
However, companies that do not qualify for this exemption or those that are part of a group where the group does not qualify are legally required to have their financial statements audited. Additionally, businesses applying for government grants, tenders, or external financing are often asked to provide audited accounts regardless of exemption status.
According to the Accounting and Corporate Regulatory Authority (ACRA), audits must be carried out by a registered public accountant or an accounting firm approved under the Accountants Act.
Step-by-Step: The Audit Process in Singapore
Step 1 Prepare Your Financial Records
This is where most delays happen. Before an auditor can begin fieldwork, your accounting team must ensure the following are complete and reconciled:
- - General ledger and trial balance
- - Bank statements and bank reconciliations
- - Accounts receivable and payable schedules
- - Fixed asset registers
- - Payroll records and CPF contribution summaries
- - GST returns and supporting tax schedules
- - Board resolutions, shareholder agreements, and minutes of meetings
The more complete and organised your records are before the auditor arrives, the faster the fieldwork stage moves. Many first-time businesses underestimate this step and end up extending timelines by weeks simply due to missing reconciliations.
Step 2 Appoint a Qualified Auditor
Your auditor must be registered with ACRA as a public accountant or be part of an approved audit firm. Under Singapore law, directors appoint the company's auditor at the Annual General Meeting (AGM) or through a resolution if it's a private company exempt from holding an AGM.
It's important to appoint the auditor early ideally before the financial year closes so they can observe year-end inventory counts or other time-sensitive procedures. Late appointments are one of the most common causes of audit delays for SMEs.
Step 3 Engagement and Planning
Once appointed, the auditor issues an engagement letter outlining the scope of work, timelines, fees, and responsibilities of both parties. This is a legally significant document read it carefully before signing.
During the planning phase, the auditor will:
- - Assess the risk profile of your business and industry
- - Understand your internal controls and accounting systems
- - Identify areas that require more intensive scrutiny (e.g., revenue recognition, related-party transactions)
- - Develop an audit plan tailored to your company's size and complexity
For SMEs, this phase is typically brief one to two working days but for companies with complex structures or high-risk transactions, it can take longer.
Step 4 Fieldwork and Evidence Gathering
This is the core of the audit process. Auditors will request and examine supporting documents to verify the accuracy of figures in your financial statements. Common audit procedures in Singapore at this stage include:
- Vouching - Tracing entries in the accounts back to source documents like invoices and contracts
- Confirmation - Sending letters to banks, debtors, and creditors to verify balances independently
- Physical verification - Checking fixed assets or inventory in person
- Analytical procedures - Comparing financial ratios and trends to identify anomalies
- Recalculation - Independently recomputing figures such as depreciation or accruals
Your team should be available during fieldwork to answer queries promptly. Delays in responding to auditor requests are a leading cause of extended timelines at this stage.
Step 5 Audit Findings and Management Letter
After fieldwork, the auditor consolidates findings. If issues are identified such as control weaknesses, unexplained variances, or potential misstatements they will raise these as audit queries or adjustments.
You may receive a management letter (also called a letter of observations) that highlights internal control weaknesses and recommendations. This is a valuable document beyond compliance it gives your business practical insights into where financial processes can be strengthened.
If there are material misstatements that need correction, your accounting team will revise the financial statements before the auditor finalises the report.
Step 6 Receiving the Final Audit Report
The auditor issues a formal financial audit report, which is attached to your company's financial statements. There are four types of audit opinions an auditor can issue:
Most compliant businesses receive an unqualified opinion. A qualified or adverse opinion signals serious issues that need to be addressed before filing with ACRA or presenting to stakeholders.
Step 7 Filing and Compliance
Once the audit report is signed, the audited financial statements must be presented to shareholders and filed with ACRA. Private limited companies are required to file their Annual Return which references the audited accounts within seven months from the end of the financial year.
Failure to file on time results in penalties from ACRA, and persistent non-compliance can trigger enforcement action. Having your audit completed well ahead of the deadline gives your team time to address any last-minute issues without pressure.
How Long Does the Audit Certification Process Take?
For a well-prepared SME in Singapore, the full process from fieldwork to signed report typically takes four to six weeks. Companies with incomplete records, complex transactions, or multiple entities can expect eight to twelve weeks or longer.
The single biggest factor in timeline is how prepared your financial records are before the auditor begins. Businesses that maintain clean, monthly-reconciled books throughout the year consistently experience faster and smoother audits.
Common Mistakes to Avoid During a Singapore Audit
- Delaying auditor appointment - Missing year-end inventory counts or other time-sensitive procedures
- Providing incomplete records - Creates back-and-forth that extends timelines significantly
- Ignoring internal control weaknesses - These surface in audit findings and can affect future financing or government applications
- Confusing compilation with audit - A compiled financial statement is not the same as an audited one and carries no independent assurance
- Leaving GST and CPF reconciliations until the last minute - These are frequently queried during fieldwork
What Makes a Good Audit Partner for SMEs?
Beyond technical competence, the right audit firm for an SME should communicate clearly, provide a realistic timeline upfront, and flag issues early rather than at the final review stage. Responsiveness matters you don't want to be chasing your auditor weeks before your ACRA filing deadline.

Frequently Asked Questions
What is audit certification in Singapore?
Audit certification in Singapore is the procedure by which a registered public accountant audits the financial statements of a company independently and issues a signed audit report stating whether the accounts present a true and fair view. Companies that are not exempt from the small company audit exemption under the Companies Act are required to do so.
How long does the audit process take in Singapore?
For a well prepared SME, the whole audit process in Singapore, from fieldwork to a signed audit report, will usually take four to six weeks. Companies with complicated finances, multiple entities or incomplete records, may take eight to 12 weeks. The best way to compress this timeline is to get your financial records in order early.
What documents do I need to prepare for a Singapore audit?
You will need to prepare your general ledger, bank reconciliations, schedules of accounts receivable and payable, fixed asset register, payroll, CPF summaries, GST returns and corporate documents such as board resolutions and minutes of meetings. Preparing these before the start of the field work will greatly reduce delays in the audit process.
What is the difference between a qualified and unqualified audit opinion?
An unqualified (clean) opinion means the financial statements are true and fair and there are no material issues. A qualified opinion is one where the auditor has identified certain exceptions or qualifications. Most compliant SMEs in Singapore receive an unqualified opinion, whereas a qualified opinion typically requires management to address the identified issues promptly.
Is a small company in Singapore required to have an audit?
Companies that satisfy two of the three criteria revenue below S$10 million, assets below S$10 million and less than 50 employees are exempted from statutory audit under the Companies Act. However, even if exempt, lenders, grant bodies and government agencies may still require audited accounts.
When must audited financial statements be filed with ACRA?
In Singapore, a private limited company must file the Annual Return, which is the audited financial statements, with the ACRA within seven months from the end of the financial year. ACRA will penalise you for late filing. You should engage your auditor early and complete the fieldwork well before the due date.
