As a trusted corporate services provider in Singapore, we at Entrust understand that business taxation can often feel complex, especially when you’re managing operations, clients, and growth at the same time. Maybe one of the most common questions we get from small and medium-sized businesses is: What is chargeable income, anyway? And more importantly, how do you calculate chargeable income? In this article, here we break it down for you. Whether you’re an entrepreneur, business owner, or just starting your money journey, understanding chargeable income is the secret to staying compliant and planning for long-term prosperity. And with our tax advisory services, you won’t have to navigate it alone.

Understanding Chargeable Income in Singapore

Chargeable income is how much of a company’s income is payable as corporation tax after business deducting taxable expenses, exemptions, and reliefs. Singapore corporation income is taxed at 17% but not the whole income. That is where chargeable income steps in to play its most crucial role in determining how much tax your business must pay.

In simple terms, chargeable income = taxable income less deductions and exemptions.

The majority of new business owners mistakenly believe that 17% of every profit goes to tax, but the Singapore tax regime provides you with numerous reliefs that keep the final amount at a bare minimum. That is why it is important to know how to calculate chargeable income correctly and that is where we can assist.

Why It Matters to Your Business

Getting chargeable income correct helps you:

  • Not overpay or underpay taxes.
  • Make best utilization of government tax schemes and reliefs.
  • Improve your business’s cash flows and financial situation.
  • Provide accurate reports for ACRA and IRAS purposes.

At Entrust, our tax consulting is simplified. We optimize our clients’awareness of their financial situation and make recommendations on how to best make use of available tax reliefs.

How to Calculate Chargeable Income – Step by Step

A step-by-step process for determining chargeable income for a business
Let us walk through a simple example of how to get to the chargeable income of a small business in Singapore.

Step 1: Start with Your Revenue

Your company earned $500,000 in revenue for the financial year.

Step 2: Subtract Business Expenses

You had the following allowable expenses:

  • Rent: $30,000
  • Salaries: $100,000
  • Office supplies: $10,000
  • Marketing: $20,000
  • Misc. operating expenses: $40,000

Total Expenses = $200,000

Step 3: Work out Your Net Profit

Net Profit = Revenue – Expenses

$500,000 – $200,000 = $300,000

Step 4: Tax Exemptions and Reliefs

Assume your business is eligible for:

Partial exemption on the first $200,000 of chargeable income

(75% on first $10,000 and 50% on remaining $190,000)

Exemption Amount = (75% of $10,000) + (50% of $190,000) = $7,500 + $95,000 = $102,500

Step 5: Final Chargeable Income

Chargeable Income = Net Profit – Exemptions

= $300,000 – $102,500 = $197,500

This final amount, $197,500 is the figure subject to 17% corporate tax.

This is just a sample example, but it illustrates the taxable income formula for chargeable income at work. Our experts at Entrust proceed to tackle each of these points with strict adherence and effectiveness for your business.

Common Deductions That Affect Chargeable Income

Some common deductible items under IRAS are:

  • Wages payable to employees
  • CPF contributions
  • Professional fees payable to specialists (lawyers, accountants, etc.)
  • Depreciation of fixed assets (subject to specific conditions)
  • Interest on business loans
