Singapore resident income tax is progressive. The key input is chargeable income, not gross salary or total bank receipts.
How the rule works
Identify taxable income, deduct allowable expenses, donations and eligible personal reliefs, then apply resident rate bands. The overall personal relief cap is generally SGD 80,000.
Calculation method
Estimated tax is the sum of the amount in each band multiplied by that band’s rate. A marginal rate does not apply to all income.
Three practical examples
- Chargeable income SGD 20,000: the first SGD 20,000 is taxed at 0%.
- At SGD 40,000: the next SGD 10,000 is taxed at 2% and the following SGD 10,000 at 3.5%, about SGD 550 total.
- At SGD 68,000: the 0%, 2%, 3.5% and 7% bands apply separately.
Special cases and limits
- Tax residence must be established from actual circumstances.
- Rent, benefits, overseas income and one-off payments may need separate treatment.
- The tool does not decide relief eligibility, penalties or rebates.
Frequently asked questions
Can I enter annual salary directly?
