Introduction
Singapore's accounting and audit sector generated S$3.5 billion in revenue in 2024 — a 7.5% year-on-year increase driven by rising demand for compliance expertise. Its 21,783 professionals maintain the governance standards and regulatory transparency that make Singapore a trusted base for multinationals and fast-growing SMEs alike.
Choosing the right audit partner within this mature market is still far from straightforward. Options range from Big Four giants with cross-border networks to specialized mid-tier firms offering personalized service at competitive rates. The wrong fit can mean missed compliance deadlines, inflated fees, or a firm whose capabilities simply don't match your business complexity.
This guide covers the top accounting and audit firms operating in Singapore in 2026 — what makes each one stand out, and how to choose the right fit based on your company's size, industry, and complexity.
TLDR
- Singapore's audit market spans Big Four giants and capable mid-tier firms, all regulated under ACRA and reporting under SFRS
- The Big Four (PwC, KPMG, EY, Deloitte) dominate with global reach and deep regulatory expertise; mid-tier firms like RSM deliver personalized service at lower cost
- The right firm depends on your company size, industry, cross-border footprint, and whether you need standalone audit or bundled tax and advisory services
- Shortlist firms on ACRA registration status, sector-specific experience, technology infrastructure, and responsiveness
Overview of Accounting & Audit Landscape in Singapore
Accounting and audit firms in Singapore perform far more than number-crunching. They conduct statutory audits mandated under the Companies Act, ensure compliance with Singapore Financial Reporting Standards (SFRS), handle ACRA filings, and provide tax advisory aligned with IRAS requirements. For any company operating in Singapore, these services are essential compliance infrastructure.
Singapore mandates statutory audits for most companies. Only "small companies" qualify for exemption — those meeting at least two of three criteria for two consecutive years:
- Revenue under S$10 million
- Total assets under S$10 million
- 50 employees or fewer
ACRA launched consultations in early 2026 to potentially raise these thresholds, so borderline SMEs should monitor legislative updates closely.
That compliance-heavy environment is driving real market growth. Audit and assurance services accounted for 50% of the sector's S$3.5 billion revenue in 2024, with mid-tier firms recording 47.4% revenue growth — outpacing even the Big Four.
The firms below represent the most consistently recognized names, selected based on market presence, service breadth, regulatory standing, and client reputation.

How We Chose These Firms
These firms were selected based on: ACRA registration and good standing, consistency across industry rankings and peer-reviewed lists, breadth of core services (audit, tax, advisory), market presence measured by staff size, and reputation drawn from publicly available client testimonials and awards.
Common mistakes businesses make when selecting an audit firm:
- Selecting on brand name alone without verifying industry-specific expertise
- Overlooking mid-tier firms that often deliver better value, faster response times, and direct partner access
- Skipping cross-border capability checks when operating across multiple jurisdictions or planning expansion
The right choice depends on your operations. Big Four firms bring global network depth, broad regulatory expertise, and extensive service lines — useful when you need international reach or complex multi-jurisdictional support. Mid-tier firms tend to cost less, move faster, and give you direct partner access. For SMEs and growing businesses that need real responsiveness over global infrastructure, that trade-off often makes more sense.
Conclusion
Singapore's accounting and audit landscape in 2026 offers strong choices across firm tiers. The Big Four dominate by scale and global reach, while mid-tier firms like RSM deliver personalized service and cost-effectiveness. The right firm is the one that aligns with your industry, scale, and compliance complexity — not just the most recognizable name.
When evaluating firms, prioritize responsiveness, technology adoption, and partner involvement. If you anticipate growth, cross-border expansion, or increased regulatory scrutiny, confirm your audit partner can scale alongside you.

Frequently Asked Questions
What are the top audit firms in Singapore?
The consistently top-ranked firms include the Big Four (PwC, KPMG, EY, Deloitte) and leading mid-tier firms such as RSM, BDO, and Baker Tilly. The right choice depends on your company size, industry, and whether you need local or cross-border expertise.
Is statutory audit mandatory for all companies in Singapore?
No. Companies qualifying as "small companies" under the Companies Act are exempt if they meet at least two of three criteria for two consecutive years: revenue under S$10 million, assets under S$10 million, and 50 employees or fewer. All other companies must conduct statutory audits under ACRA requirements.
What is the difference between Big Four and mid-tier audit firms in Singapore?
Big Four firms offer broader global networks, more service lines, and deeper regulatory expertise suited to large MNCs and complex cross-border transactions. Mid-tier firms typically provide more direct partner access, faster turnaround, and more competitive pricing — ideal for SMEs and mid-market businesses.
How much does a statutory audit cost in Singapore?
Audit fees vary based on company size, complexity, and the firm engaged. Standard SME audits (revenue under S$5 million) typically range from S$2,500 to S$4,500; larger SMEs (S$5–10 million revenue) can expect S$5,000 to S$9,000. Complex operations or specialized industries typically add a 20–30% premium on top of base fees.
How do I choose the right audit firm for my business in Singapore?
Start by confirming ACRA registration, then evaluate industry experience, partner involvement, and technology capabilities relative to your business size. Request proposals from two or three firms, compare pricing and responsiveness, and verify each firm's track record in your sector before deciding.
Can foreign companies use their overseas auditors for their Singapore-incorporated entity?
No. Singapore-incorporated companies must engage an ACRA-registered public accountant or approved accounting entity for their statutory audit — the parent company's overseas audit arrangements do not apply.
