Singapore Income Tax 2026: IRAS Brackets, CPF Rules & Expat Package Optimization

The Statutory Architecture of Singapore Taxation

Singapore operates on a territorial basis with one of the most competitive progressive tax structures in the world, administered by the Inland Revenue Authority of Singapore (IRAS):

• First S$20,000: 0% tax.
• Next S$10,000 (S$20,001–S$30,000): 2%.
• Next S$10,000 (S$30,001–S$40,000): 3.5%.
• Next S$40,000 (S$40,001–S$80,000): 7%.
• Next S$40,000 (S$80,001–S$120,000): 11.5%.
• Next S$40,000 (S$120,001–S$160,000): 15%.
• Next S$40,000 (S$160,001–S$200,000): 18%.
• Next S$40,000 (S$200,001–S$240,000): 19%.
• Next S$40,000 (S$240,001–S$280,000): 19.5%.
• Next S$40,000 (S$280,001–S$320,000): 20%.
• Next S$180,000 (S$320,001–S$500,000): 22%.
• Next S$500,000 (S$500,001–S$1,000,000): 23%.
• Above S$1,000,000: 24%.

Real Case Scenario: Tech Lead on S$180,000 Annual Base

Consider an Employment Pass professional earning S$15,000 per month (S$180,000 annually):

1. CPF Deductions:

   • Because foreign pass holders are exempt from CPF, employee deduction is S$0.
   • Chargeable income = S$180,000.

2. IRAS Tax Calculation:

   • Tax on first S$160,000 = S$13,950.
   • Tax on remaining S$20,000 at 18% = S$3,600.
   • Total Annual Income Tax: S$17,550.
   • Effective Tax Rate: 9.75%.

3. Monthly Take-Home Cash Flow:

   • Annual net after tax: S$180,000 - S$17,550 = S$162,450.
   • Monthly net cash: S$13,537.

Comparing Employment Pass vs. Singapore Permanent Resident (PR)

For Singapore PRs and citizens, mandatory CPF applies up to the ordinary wage ceiling:

• Employee contributes 20% (up to S$1,360/month based on current wage ceilings).
• Employer contributes 17% match.
• While CPF reduces immediate take-home cash, CPF contributions enjoy full tax relief, lowering taxable chargeable income.
