What does an SME need from an accounting firm?
Most Singapore companies need regular bookkeeping, annual financial statements, an annual return to ACRA, the Estimated Chargeable Income (ECI) and corporate tax return to IRAS, and GST filing if registered. Larger companies also need a statutory audit by a public accounting firm.
The firms on this list fall into three groups. Online accounting providers (Osome, Sleek) bundle bookkeeping software and filings into a subscription. Corporate service providers (3E Accounting, InCorp Global) add incorporation, company secretarial, payroll and immigration work. Audit and advisory firms (RSM, Foo Kon Tan) belong to international networks and provide audit, tax and advisory work for mid-sized companies. Whether your company needs an audit depends on its size; check ACRA’s current small company criteria or ask the firm.
How did we rank these accounting firms?
We favoured firms that publish prices and say exactly which filings are included, then weighed the breadth of compliance services and named credentials such as ACRA filing agent status, professional memberships, ISO certification or network membership.

Frequently asked questions
Does my small company need an audit?
Not always. Smaller companies may qualify for audit exemption under ACRA’s small company rules. Check ACRA’s current criteria or ask your accountant.
What is the difference between an accounting firm and a corporate service provider?
Accounting firms focus on bookkeeping, accounts, tax and audit. Corporate service providers, such as 3E Accounting and InCorp Global, also handle incorporation, company secretarial work and work passes.
What filings are included in an accounting plan?
It varies. Osome’s plans include ECI, Form C/C-S and unaudited financial statements, with GST filing included only on its Scale plan. Ask each firm for a written list.
Can one firm handle payroll too?
Yes. Osome, InCorp Global and Sleek list payroll services. Check whether it is priced per employee.
How did you rank these firms?
We weighed price transparency, scope of compliance work and stated credentials, using only what each firm publishes. We update the list when those facts change.
