The 10 Best Accounting Firms in Singapore (2026)

Updated October 2026 · 10 picks

The best accounting firms in Singapore in 2026 are the Big Four — PwC, Deloitte, EY and KPMG — for audit and tax at scale; BDO, Baker Tilly, Forvis Mazars, RSM and Grant Thornton for SMEs and family businesses; and 3E Accounting for start-up incorporation, bookkeeping and filings. Check audit firms on ACRA's register.

Every Singapore company must keep proper accounts, file an annual return with ACRA and file corporate tax returns with IRAS, and many need an audit. Small companies (broadly, those meeting two of three tests on revenue, assets and staff) are exempt from audit, which is why many start-ups only need bookkeeping, tax filing and a company secretary. Only ACRA-registered public accountants can sign an audit report.

1. PwC Singapore — Marina Bay

The largest of the Big Four in many markets, with deep audit and tax teams in Singapore.

Specialty Audit, corporate and personal tax, deals, consultingBest for Listed companies, multinationals, financial institutions and large private groups

PwC is one of the Big Four professional services networks, and its Singapore firm provides audit and assurance, tax, deals and consulting from Marina One East Tower. Its tax practice includes corporate tax, transfer pricing, GST and services for globally mobile employees.

It is built for large companies, but its people and organisation tax team is relevant to senior expats whose employers use PwC for their tax filings. Smaller businesses will usually find a mid-tier firm better value.

Good to know: If your employer pays for tax filing through PwC, ask HR for the tax-briefing contact before your first April filing.

Frequently asked questions

Does my Singapore company need an audit?

Not always. A private company that qualifies as a 'small company' — broadly, meeting at least two of three criteria on annual revenue (S$10 million or less), total assets (S$10 million or less) and employees (50 or fewer) for two consecutive years — is exempt from statutory audit. It must still keep accounts, prepare financial statements and file with ACRA and IRAS. Check the current criteria on ACRA's website.

How much does an accountant cost in Singapore?

Bookkeeping and annual filing packages for a small, low-transaction company commonly start from a few hundred dollars a month or a few thousand a year, depending on volume; audits and advisory work at mid-tier and Big Four firms cost much more. Ask for a fixed annual quote that lists exactly which filings are included.

What are the main tax filing deadlines in Singapore?

For companies, the corporate income tax return (Form C-S, C-S Lite or C) is due by 30 November each year, and an Estimated Chargeable Income is generally due within three months of the financial year-end. Individuals file personal income tax by mid-April (18 April for e-filing). GST-registered businesses file quarterly. Confirm current dates with IRAS.

Do I have to register for GST?

You must register for GST if your taxable turnover exceeded S$1 million in the past 12 months or is expected to over the next 12. Below that, registration is voluntary. An accountant can advise whether voluntary registration makes sense for your business.

Do I need a Singapore accountant for my personal taxes?

Most employees file their own Singapore tax return online with IRAS, and many have no return to file under the No-Filing Service. Expats with foreign income, rental property or an equity plan often benefit from an adviser. Americans also have US filing duties wherever they live, so most use a specialist US expat tax firm.
