Singapore's corporate income tax (CIT) system remains a cornerstone of its pro-business environment in 2024, attracting both local and international companies. Its design emphasizes simplicity, transparency, and competitiveness, with specific provisions aimed at encouraging investment and economic growth.
Calculating Corporate Income Tax
The calculation of corporate income tax in Singapore follows a clear and methodical process:
- Step 1: Determine Gross Income: This encompasses all income earned by a company during a financial year (FY). It includes business income, investment income (interest, dividends, royalties), and other forms of revenue.
- Step 2: Deduct Allowable Expenses: Companies can deduct expenses directly incurred in generating their income. These include operating costs, employee salaries, rent, depreciation of business assets, and research and development (R&D) costs.
- Step 3: Arrive at Net Income (Chargeable Income): The deduction of allowable expenses from gross income results in net income, also known as chargeable income. This is the amount upon which tax is levied.
- Step 4: Apply Corporate Tax Rate: Singapore has a flat corporate tax rate of 17% (see section 2 below). This rate is applied to the chargeable income to determine the tax payable.
- Step 5: Deduct Tax Credits: Companies may be eligible for various tax credits, such as the Corporate Income Tax Rebate, foreign tax credits, and incentives for specific industries. These credits are deducted from the tax payable, reducing the final tax liability.
Accounting Practices: Singapore generally follows the Financial Reporting Standards (FRS) set by the Accounting Standards Council (ASC), which align with International Financial Reporting Standards (IFRS).

- Trading and Other Income: Income from any other sources, including gains from the sale of assets (subject to certain exemptions).
Exempt Income
Singapore offers exemptions for various types of income to incentivize specific activities or to avoid double taxation:
- Foreign-Sourced Dividends: Dividends received from foreign companies are generally exempt if specific conditions are met (e.g., shareholding threshold, tax paid in the source country).
