Understanding Singapore’s Taxation System for Newly Incorporated Businesses

Understanding Singapore’s taxation system for newly incorporated businesses is crucial for any entrepreneur looking to start a business in Singapore. Here is an in-depth guide to help you understand the basics of Singapore’s taxation system for newly incorporated businesses:

1. Types of Business Entities

Before diving into the tax system, it’s crucial to understand the various types of business entities you can choose from when incorporating in Singapore. The most common ones include:

a. Sole Proprietorship

  • A sole proprietorship is the simplest form of business entity, owned and operated by a single individual.
  • The individual assumes full personal liability for the business’s debts and obligations.
  • Taxation: The business income is treated as personal income and taxed at the individual’s personal tax rate.

b. Partnership

  • A partnership is formed when two or more individuals or entities come together to operate a business.
  • Partners share profits and losses as per the partnership agreement.
  • Taxation: Similar to sole proprietorship, partnership income is taxed at the individual partner’s personal tax rates.

c. Private Limited Company (Pte Ltd)

  • A private limited company is a separate legal entity from its shareholders, offering limited liability protection.
  • It can have up to 50 shareholders and is the most common choice for entrepreneurs.
  • Taxation: Company profits are taxed at the corporate tax rate, which is typically lower than personal tax rates.

2. Goods and Services Tax (GST)

Singapore imposes a Goods and Services Tax (GST) on the supply of goods and services. As a newly incorporated business, you must understand your GST obligations:

  • Registration: You need to register for GST if your annual turnover exceeds or is expected to exceed SGD 1 million. Voluntary registration is also possible if your turnover is below this threshold.
  • Collection and Payment: Once registered, you must charge GST on your sales and remit the collected GST to the Inland Revenue Authority of Singapore (IRAS).
  • Input Tax: You can claim GST incurred on your business purchases and expenses as input tax, offsetting it against the GST collected.

3. Corporate Income Tax

Corporate income tax is a vital component of Singapore’s taxation system, and it is known for its competitiveness:

  • Tax Rate: Singapore’s corporate income tax rate is typically 17%.
  • Partial Tax Exemption: Newly incorporated companies enjoy partial tax exemptions, which reduce their effective tax rates. For the first SGD 200,000 of chargeable income, a 75% exemption is applied, while a 50% exemption is applied to the next SGD 300,000.
  • Start-up Tax Exemption: Start-up companies can enjoy a tax exemption on their first SGD 100,000 of chargeable income for the first three consecutive years.
  • Tax Residency: To qualify for these exemptions, a company must be considered a tax resident in Singapore. This typically means that the management and control of the company are exercised in Singapore.

4. Withholding Tax

Singapore imposes withholding tax on certain payments made to non-resident individuals or entities. Key points to note:

  • Rates: Withholding tax rates vary depending on the nature of payments (e.g., interest, royalties, fees), but they typically range from 0% to 15%.
  • Double Taxation Agreements (DTAs): Singapore has an extensive network of DTAs with many countries, which can reduce or eliminate withholding tax on specific payments.

5. Foreign-Sourced Income

Singapore follows a territorial tax system, which means that income earned outside Singapore is generally not subject to taxation. However, there are exceptions for certain foreign-sourced income, such as:

  • Foreign Dividends: These are generally tax-exempt in Singapore, provided certain conditions are met.
  • Foreign Branch Profits: Income from a foreign branch may be subject to tax in Singapore.

6. Tax Incentives and Grants

To further support businesses, Singapore offers various tax incentives and grants, such as:

  • Pioneer Certificate: This incentive provides significant tax exemptions for companies involved in pioneering activities in Singapore.
  • Investment Allowances: Companies can claim investment allowances on qualifying capital expenditure.
  • Productivity and Innovation Credit (PIC) Scheme: The PIC scheme offers tax deductions or cash payouts for qualifying activities that promote productivity and innovation.

7. Compliance and Reporting

Singapore places great importance on tax compliance and reporting. Businesses are required to:

  • Keep accurate records of their financial transactions.
  • File annual tax returns with the IRAS.
  • Comply with transfer pricing regulations if they engage in related-party transactions.
  • Prepare financial statements in accordance with Singapore Financial Reporting Standards (SFRS).

8. Seeking Professional Advice

Navigating Singapore’s taxation system, especially for newly incorporated businesses, can be complex. It’s advisable to seek professional advice from tax consultants or accounting firms well-versed in Singapore’s tax laws and regulations. They can help you optimize your tax position, ensure compliance, and take advantage of available incentives.


Singapore’s taxation system for newly incorporated businesses is designed to be straightforward, competitive, and supportive of entrepreneurship. By understanding the different tax obligations and incentives, businesses can make informed decisions that contribute to their growth and success in this thriving business hub. However, as tax laws and regulations can change over time, it’s essential to stay updated and seek professional guidance when necessary to make the most of Singapore’s business-friendly environment.
