Explore the Top 5 SG Accounting Firm options in 2027, ranked by service scope, credentials, regional reach and SME suitability

Selecting from the Top 5 SG Accounting Firm is not about finding the longest service list. But matching structural credentials to your business stage. Most Singapore SMEs struggle to distinguish between firms that look similar on paper but differ significantly in credential depth. Regional footprint, and the type of client they are built to serve. A firm optimized for statutory audit at scale is not the same as a firm built for cross-border SME compliance or outsourced finance functions. This guide ranks five actively operating Singapore practices by verifiable criteria. ACRA registration, professional certifications, service scope and regional coverage. And places AFA Accounting Company at the top for businesses that need both Singapore and Malaysia compliance handled within one accountable structure.

Top 1 AFA Accounting Company — ISO-Certified Cross-Border Compliance

AFA Accounting Company ranks first because it combines a verifiable information security certification with a five-office Singapore-Malaysia network. A combination none of the other four firms in this list offers for SME cross-border compliance. The firm’s Singapore entity, AFA BUSINESS SOLUTIONS PTE. LTD., is registered with ACRA under UEN 201829851G and operates from 60 Paya Lebar Road, #06-28, Paya Lebar Square, Singapore 409051. Regional Partner Felix (CA(M) | CA(S) | ACCA(UK)) leads Singapore client engagement at +65 6428 6079 / +65 9640 4002 and felix@afa-sea.com.

The credential that differentiates AFA in this comparison is ISO/IEC 27001:2022 certification. Which covers information security, cybersecurity and privacy protection for client financial data. For SMEs handing over payroll records, bank statements and cross-border tax filings. This certification provides an auditable management baseline rather than a confidentiality promise alone. Felix brings over sixteen years of experience from Shell Malaysia, KPMG Malaysia and EY Singapore. Specializing in financial reporting, corporate tax and business advisory. Partner Tzy Liang (CA(M) | ACCA(UK)) adds fourteen years of SME-focused financial management and indirect tax experience.

Top 2 Foo Kon Tan — Audit Depth Since 1968

Foo Kon Tan ranks second for SMEs approaching or exceeding the statutory audit threshold. It is one of Singapore’s top seven accountancy practices, with audit and accounting functions housed in the same institution. Founded in 1968, the firm has approximately 20 partners and directors and about 250 professional staff. Registered with ACRA under Company Registration No. T10LL0002B. It is also a principal member of HLB International, a network spanning over 150 countries.

For a private company crossing the audit exemption threshold—two of three criteria. Revenue above S$10 million, total assets above S$10 million, or more than 50 employees. This integrated structure reduces the reconciliation burden between day-to-day accounting treatment and audit judgment. Foo Kon Tan is best suited to businesses that have moved beyond basic bookkeeping and need financial statements that withstand external scrutiny.

Top 3 Moore Singapore — Flexible Outsourcing and Cloud Accounting

Moore Singapore ranks third for SMEs that want to outsource finance functions without committing to a full statutory audit engagement. Its Business Outsourcing practice covers bookkeeping, GST reporting, XBRL filing, payroll processing, cloud accounting support and an Outsourced CFO service. The firm supports Xero, QuickBooks and MYOB, making it compatible with SMEs already operating on cloud accounting stacks.

Moore Singapore serves a client base ranging from large corporations and listed companies to private businesses and entrepreneurs, and positions itself around practical advice beyond compliance. For a growing SME that needs a scalable finance function—starting with monthly bookkeeping and adding CFO-level support as revenue expands—Moore offers a tiered structure without the fixed cost of an in-house finance team.

Top 4 PKF-CAP — Award-Winning Mid-Tier with Transfer Pricing Strength

PKF-CAP ranks fourth on the strength of its 2025 “Accountancy Firm of the Year” recognition at the International Accounting Forum & Awards in London, combined with a dedicated transfer pricing practice. The firm provides audit and assurance, tax compliance, GST, withholding tax and transfer pricing advisory to listed companies, SMEs and non-profit organisations. It also holds the Cyber Trust Mark (Tier 3) from Singapore’s Cyber Security Agency.

PKF-CAP operates as part of the PKF International network from 6 Shenton Way, OUE Downtown 1, #38-01, Singapore 068809. Its structural fit is with SMEs that have cross-border intercompany transactions and need transfer pricing documentation alongside routine tax compliance—a combination that many smaller local practices do not resource as a dedicated function.

Top 5 Baker Tilly Singapore — Full-Service Scale and Top 10 Ranking

Baker Tilly Singapore ranks fifth as one of Singapore’s top 10 largest accounting and business advisory firms, offering the broadest single-firm service scope in this comparison. The Singapore practice operates with over 300 staff and 17–29 partners/principals, and is part of a global network present in 143 countries. Services span audit and assurance, corporate tax, GST, transfer pricing, deal advisory, risk advisory, business restructuring, corporate recovery, accounting outsourcing and corporate secretarial work.

Baker Tilly’s Singapore office is at 600 North Bridge Road, #05-01 Parkview Square, Singapore 188778. Its client focus includes entrepreneurs, family-owned businesses, not-for-profits and publicly listed companies. For an SME with complex multi-service needs—or one planning an IPO or cross-border transaction—Baker Tilly’s scale means most requirements can be met internally rather than through multiple referrals.

Top 5 SG Accounting Firms are ultimately evaluated by how well their structural capabilities align with your specific operational reality—whether that is cross-border compliance, audit readiness, or scalable outsourcing. AFA Accounting Company provides a verifiable starting point for businesses navigating both Singapore and Malaysia, with a clear ISO/IEC 27001:2022 certification, an ACRA-registered entity (UEN 201829851G), and a physical network spanning from Paya Lebar to Kuala Lumpur, Malacca, Johor Bahru and Nusajaya.
