Regulatory Audit Requirements in Singapore: A Guide for Business Owners
Singapore is known for its strong regulatory framework, which ensures that businesses operate transparently and maintain high standards of financial integrity. One of the key aspects of corporate compliance in Singapore is the audit requirement imposed on businesses by the Accounting and Corporate Regulatory Authority (ACRA), Inland Revenue Authority of Singapore (IRAS), and other governing bodies.
Understanding regulatory audit requirements is essential for business owners to avoid penalties, ensure financial credibility, and meet compliance obligations. This article provides a comprehensive guide to the audit requirements in Singapore, including statutory audits, industry-specific audits, audit exemptions, and best practices for compliance.
1. What is a Regulatory Audit?
A regulatory audit is an independent examination of a company’s financial statements to ensure compliance with Singapore’s corporate laws, financial reporting standards, and tax regulations.
The primary objective of a regulatory audit is to provide assurance that a company’s financial statements are accurate, fair, and free from material misstatements.
Regulatory audits in Singapore are primarily governed by:
- The Companies Act (Cap 50)
- Singapore Financial Reporting Standards (SFRS)
- ACRA’s Audit Regulations
- IRAS Tax Audit Requirements
Failure to comply with audit requirements can result in financial penalties, disqualification of directors, and legal consequences.
2. Who Needs to Undergo an Audit in Singapore?
A. Statutory Audit Requirements
According to the Companies Act, companies in Singapore must appoint an external auditor and undergo a statutory audit if they do not qualify for audit exemption.
B. Audit Exemption Criteria
A company qualifies for audit exemption if it:
✅ Is a private company throughout the financial year
✅ Meets at least two out of three of the following conditions:
- Annual revenue ≤ S$10 million
- Total assets ≤ S$10 million
- Number of employees ≤ 50
C. Companies That Must Undergo an Audit
Certain businesses must undergo mandatory audits, regardless of size:
✅ Public companies listed on the Singapore Exchange (SGX)

If a company does not qualify for audit exemption, it must appoint an auditor within 3 months from its incorporation date.
3. Different Types of Regulatory Audits in Singapore
Businesses in Singapore may be subject to various types of regulatory audits depending on their industry and operations.
A. Statutory Audit
A statutory audit is the standard audit required under the Companies Act for businesses that do not qualify for audit exemption. It ensures financial statements comply with the Singapore Financial Reporting Standards (SFRS).
Who conducts it?
- A licensed external auditor registered with ACRA.
What does it cover?
- Verification of financial statements (profit & loss, balance sheet, cash flow).
- Internal control evaluation and fraud risk assessment.
- Regulatory compliance check under ACRA and IRAS.
B. Tax Audit (IRAS Tax Compliance Audit)
The Inland Revenue Authority of Singapore (IRAS) may conduct tax audits to ensure businesses comply with corporate tax, GST, and withholding tax laws.
When does IRAS conduct tax audits?
- If there are discrepancies in tax filings.
- If a company is claiming high tax deductions.
- If IRAS detects underreporting of income.
Common tax compliance issues IRAS audits include:
✅ Incorrect GST reporting

✅ Unreported revenue or transactions
How to prepare for a tax audit?
✅ Keep detailed tax records for at least 5 years.

✅ Improve internal processes and efficiency.
✅ Ensure compliance with company policies.
