Singapore taxes resident individuals on a progressive schedule administered by the Inland Revenue Authority of Singapore (IRAS). The first slice of chargeable income is tax-free and each higher band is taxed at a higher marginal rate, peaking at 24%. This free calculator applies the full 11-bracket schedule so you can see exactly how much tax you owe and your effective rate.
How it works
Tax is computed band-by-band on your chargeable income (income after reliefs and deductions). IRAS publishes a cumulative table: each band has a flat tax amount on the income up to its threshold, plus a marginal rate on the excess.
The bands (Year of Assessment 2024 onward) are:
First 20,000 0% tax 0
Next 10,000 2% (to 30,000)
Next 10,000 3.5% (to 40,000)
Next 40,000 7% (to 80,000)
Next 40,000 11.5% (to 120,000)
Next 40,000 15% (to 160,000)
Next 40,000 18% (to 200,000)
Next 40,000 19% (to 240,000)
Next 40,000 19.5% (to 280,000)
Next 40,000 20% (to 320,000)
Next 180,000 22% (to 500,000)
Next 500,000 23% (to 1,000,000)

Example
For a chargeable income of S$80,000: the first S$20,000 is free, the next S$10,000 at 2% = S$200, the next S$10,000 at 3.5% = S$350, and the final S$40,000 at 7% = S$2,800. Total tax = S$3,350, an effective rate of about 4.2%. Your marginal rate at that income is 7% — the rate that would apply to the next dollar earned.
