What is an Audit Firm?

An audit firm provides accounting and auditing services to other companies. Such activity aims to promote good accounting standards, control organisational risk and inefficiencies, ensure compliance, etc. An audit firm can provide accounting, bookkeeping, or consulting services but tend to focus and specialise on audit work.

Generally, auditors are associated with the world of finance and accounting, where they play the role of financial gatekeepers. They are experts in this area and adopt an investigative position, verifying the work of accountants. The purpose of this scrutiny is to ensure the legality and validity of records, the accuracy of statements, etc. An audit is a ‘fair and true’ review of a company’s financial statements.

All auditors must issue an opinion or report known as the Audited Financial Statement. They are required to be objective and independent to promote efficient governance and compliance. Auditors can be:

  • Internal Auditors – usually employees who review their company’s financial statements, risk, etc.
  • External Auditors – hail from outside the company to handle accounting and financial statements.

Mention the word ‘audit’ and what usually comes to mind is a review of a company’s books. In all fairness, this is what audits generally are. However, there are quite a few types of audits that a company can do, and these include:

  • Statutory and non-statutory financial audits
  • Group or consolidated audits
  • Tax and VAT inspection audits
  •  Business operations audits
  •  Risk management audits
  • Systems performance and security audits
  •  Forensic audits


Why Start an Audit Firm in Singapore?

In Singapore, the Companies Act requires non-dormant businesses to submit their financial statements for annual company audits. Done by external auditors or a public accountant, statutory audits are the sole province of public accounting firms. Currently, there are only 443 public accounting firms in Singapore. Hence, starting an audit firm is a viable business idea that underpins the nation’s economic blueprint.

Singapore’s status as a business hub continues to drive the growth of the accounting services industry. Company audits follow the Singapore Standards on Auditing (SSA) set by the Institute of Singapore Chartered Accountants (ISCA). Exemption to statutory audits applies to companies that meet any two of the following criteria per financial year:

  • Where the total annual revenue is below SGD 10 million.
  • Where the total assets are below SGD 10 million.
  • The number of employees is below 50.

Aside from the compulsory statutory audit, companies benefit from regular audits of their business. Such audits provide impartial information to owners and shareholders about the management and financial situations. Audit firms thus form the cornerstone of trust and obligation between all relevant stakeholders.


What Does an Audit Firm Need?

When considering the needs of an audit firm, the most obvious one has accountants and auditors. By law, only public accountants or registered agents can establish an auditing or accounting firm in Singapore. 3E Accounting Singapore is an example of a registered agency that can incorporate an audit firm.

Requirements to Start an Audit Firm in Singapore

Businesses in Singapore have a legal requirement to register or incorporate their company structures. 3E Accounting’s guide to company registration offers an in-depth read of the incorporation process and business entities available.

Registration is usually a straightforward process and can be done online via ACRA’s business platform, BizFile. However, company incorporation is slightly more complex for firms that offer audits and reporting of financial statements.

Public accounting firms can only offer public accountancy services with an ACRA registration under the Accountants Act. The ACRA website specifies three types of accounting business structures that apply:

  • Public Accounting Firms (PAFs) – sole proprietorship or partnership business structures.
  • Accounting Limited Liability Partnerships (ALLPs) – incorporated LLP and has registration requirements under the LLP Act and the Accountants Act.
  • Public Accounting Corporations (PACs) – Exempt Private Companies with registration requirements under the Companies Act and the Accountants Act.

You will need to log in to BizFile and first get approval for your company name. Next, you’ll need to apply to incorporate your firm. There are specific rules and procedures to be aware of, which include the following:

  • The sole proprietor or two-thirds of the partnership or corporation must be a public accountant partner(s).
  • At least one public accountant partner must be ordinarily resident in Singapore.
  • Submit incorporation documents (Articles and Memorandum of Association, Partnership Deed, directors and shareholders information, registered business address, etc.)
  •  Pay the relevant fees.
  • Register with the Inland Revenue Authority of Singapore (IRAS).

Your audit firm will receive a Unique Entity Number (UEN) and a free business profile upon successful registration. Opening a bank account, getting business insurance and setting up an office should also be on your to-do list.
