In Singapore, there is no minimum amount for audit. All companies, regardless of their size or revenue, are required to undergo an annual audit, unless they meet specific criteria for exemption under the Singapore Companies Act. The exemption criteria include small companies, dormant companies, and exempt private companies with 20 or fewer shareholders and no corporate shareholders. However, companies that are exempt from audit still have to prepare their financial statements and file them with the Accounting and Corporate Regulatory Authority (ACRA).
