How Much Do Audit Fees Cost in Singapore? A Comprehensive Analysis from Small Businesses to Large Corporations

In Singapore, a business hub renowned for efficiency, transparency, and the rule of law, audit services play a crucial role in corporate compliance. Whether a startup or a multinational corporation, all businesses are required to undergo an independent audit of their financial statements annually and submit reports to relevant regulatory authorities. Understanding the composition and influencing factors of audit fees is essential for budget planning and effective financial management.

What Is a Basic Audit Service?

A basic audit refers to the process by which an independent certified public accountant or professional firm examines and verifies the authenticity, fairness, and compliance of a company’s financial statements. According to requirements set by the Accounting and Corporate Regulatory Authority ACRA, all registered companies must timely submit audited financial statements after the end of each fiscal year-unless they qualify for exemption. In addition, corresponding tax filings must be submitted to the Inland Revenue Authority of Singapore IRAS.

The scope and complexity of audits vary significantly depending on the size of the business. Small enterprises may require only a basic review of accounts, while large corporations often involve consolidated financial statements, cross-border transactions, and internal control system assessments.

Key Factors Influencing Audit Fees

1. Company Size and Business Complexity

The scale of assets, revenue, number of employees, and whether the company operates multiple subsidiaries or branches directly affect the complexity and time required for an audit. For instance, a small enterprise with annual revenue below SGD 5 million typically involves a simpler audit process. In contrast, auditing a multinational group requires handling multi-jurisdictional regulations, foreign currency conversions, and consolidated reporting, which increases both time and cost.

2. Completeness and Accuracy of Financial Records

If a company maintains clear, well-organized, and easily accessible accounting records, the auditor's work becomes more efficient, thereby reducing overall costs. Conversely, disorganized records, missing documentation, or inconsistent systems can make the audit process cumbersome, requiring additional labor and time.

3. Reputation and Qualifications of the Audit Firm

Singapore hosts numerous local and internationally recognized audit firms, including the Big Four-Deloitte, PwC, EY, and KPMG-as well as smaller, specialized practices. Generally, the Big Four charge higher fees due to their brand reputation, global network, and high service standards. Smaller firms, however, offer more competitive pricing and may better suit the needs of small and medium-sized enterprises SMEs.

4. Industry Characteristics

Companies across different industries face varying financial structures and risk profiles. For example, financial institutions, real estate developers, and technology firms often deal with complex valuation models and stringent compliance requirements, making audits more challenging and costly.

5. Additional Service Requirements

Some companies request value-added services such as tax planning, internal control recommendations, or risk management consulting alongside standard audit procedures. These additional services naturally increase the total audit cost.

Reference Ranges for Audit Fees by Company Type

Small Enterprises Annual Revenue < SGD 5 Million

For these businesses, audit fees typically range between SGD 1,500 and SGD 5,000. If the company maintains clean books and has a simple structure, some local small firms may even offer services at lower prices. However, it is important to note that low fees may sometimes reflect lower service quality, so choosing a reputable provider is advisable.

Medium-Sized Enterprises Annual Revenue SGD 5-50 Million

These companies usually have more complex transaction types and management processes, resulting in increased audit workload. Based on recent market surveys, audit fees generally fall between SGD 5,000 and SGD 20,000, depending on the complexity and scope of the audit.

Large Enterprises Annual Revenue > SGD 50 Million

Auditing large corporations often involves cross-departmental coordination and international team support. Publicly listed companies or foreign-owned entities may also need to comply with International Financial Reporting Standards IFRS or other specific frameworks. According to 2025 media reports, top-tier firms charge anywhere from tens of thousands to hundreds of thousands of Singapore dollars for auditing large enterprises. For example, a tech company recently disclosed in its annual report that it paid approximately SGD 180,000 to its auditor in 2025.

Recent Industry Trends

With Singapore actively promoting digital transformation, an increasing number of companies are adopting automated financial systems, which has had a significant impact on the audit industry. On one hand, intelligent accounting software improves the efficiency of financial processing, potentially lowering audit costs. On the other hand, audit firms are increasingly leveraging data analytics tools to enhance accuracy and efficiency.

Moreover, as global expectations around ESG Environmental, Social, and Governance disclosures grow stricter, some companies are incorporating ESG-related elements into their audits. This trend expands both the breadth and depth of audit work, potentially leading to additional charges.

How to Control Audit Costs Effectively

1. Prepare Financial Documents in Advance Ensuring organized records and complete supporting documents can significantly improve audit efficiency.

2. Choose the Right Audit Firm Select a service provider based on your business needs and budget-there’s no need to automatically opt for a Big Four firm.

3. Maintain Regular Communication Open and timely communication with the audit team helps resolve issues promptly, minimizing delays caused by miscommunication.

4. Bundle Services When Possible If you require additional financial or tax advisory services, consider bundling them with your audit to benefit from a more favorable overall rate.

Conclusion

Overall, audit fees in Singapore vary widely depending on company size, industry type, and the level of service required. Businesses should carefully assess their own circumstances, anticipate audit costs realistically, and select reputable professionals to ensure compliance while maximizing cost-effectiveness.
