Introduction

In Singapore, audits are a critical part of corporate governance and financial accountability. While many business owners associate audits with the annual statutory requirement, the reality is that there are several different types of audits, each serving a unique purpose.

Understanding these audit types can help business owners choose the right service for compliance, risk management, and strategic improvement. This article explores the most common types of audit services in Singapore, how they work, and when your business might need them.

A statutory audit is the most recognised form of audit in Singapore. It is required under the Singapore Companies Act for companies that do not qualify for audit exemption.

Provide recommendations for improvement.

When it’s useful:

Verify that GST input tax claims are supported by proper documentation.

When it’s required:

Periodically conducted by IRAS on GST-registered businesses.
When discrepancies are detected during IRAS risk assessments.

A due diligence audit is conducted before major business transactions such as mergers, acquisitions, or investments.

Purpose:

Example:
If you’re acquiring another business, due diligence ensures you are aware of its debts, contracts, and operational risks.

An IT audit evaluates a company’s information technology infrastructure, data management, and cybersecurity measures.

Purpose:

Ensure data security and integrity.
Verify compliance with IT governance standards.
Identify vulnerabilities in IT systems.

Ensure compliance with grant agreements.
Provide accountability to the funding body.

Example in Singapore:

Companies using Enterprise Singapore’s Market Readiness Assistance (MRA) grant may need an audit before grant disbursement.
