The Singapore Personal Income Tax calculator helps tax residents compute their chargeable income, applicable progressive tax, and net tax payable after personal reliefs and rebates for a given year of assessment. Singapore operates one of the most competitive personal income tax regimes in the world with a progressive rate structure that begins at 0% for income up to $20,000 and rises to 24% for income above $320,000. Tax residents — individuals who are in Singapore for at least 183 days in the year — are taxed on Singapore-sourced income only, not on overseas remittances. The tax computation begins with total employment income including salary, bonuses, and benefits-in-kind, then deducts allowable expenses and approved reliefs. Key reliefs include CPF contributions (employee share), Earned Income Relief (up to $8,000 for seniors), NSman Relief, parent relief ($9,000 per parent), spouse relief ($2,000), and child reliefs. The total personal income tax reliefs are capped at $80,000 per year. After deducting reliefs from assessable income, progressive tax rates are applied to the resulting chargeable income. Tax rebates such as the Parenthood Tax Rebate (PTR) and elderly rebates further reduce the final tax payable. For non-residents, the rate is the higher of a flat 15% on employment income or the resident progressive rates applied without personal reliefs. Understanding your Singapore income tax position helps with financial planning, SRS contributions, and optimising the mix of available reliefs.
Chargeable Income = Assessable Income - Allowable Reliefs (capped at $80,000); Tax Payable = Progressive Rate on Chargeable Income - Rebates; Effective Rate = Tax Payable / Assessable Income × 100%
- 1Compute total assessable income: employment income, trade income, rental income, and other taxable sources.
- 2Deduct allowable employment expenses and approved deductions to arrive at assessable income.
- 3Apply personal reliefs (CPF, earned income, family-related reliefs) subject to the $80,000 cap.
- 4Calculate chargeable income = assessable income minus total reliefs.
- 5Apply the progressive tax rate schedule to chargeable income using the bracket-by-bracket method.
- 6Subtract any rebates (Parenthood Tax Rebate, elderly rebates) from the computed tax.
- 7Arrive at final income tax payable for the year of assessment.
Singapore's low rates reward moderate earners significantly
After $13,000 of reliefs, chargeable income is $47,000. Progressive tax is approximately $1,500 — a very low effective rate due to the generous 0% band up to $20,000.
Reliefs substantially reduce tax
Even at $200K income, aggressive use of CPF, SRS, and family reliefs reduces the effective tax rate to around 10%. This illustrates how important relief planning is.
24% marginal rate applies above $320,000
The top marginal rate is 24% but the effective rate is only ~16% due to the progressive structure and lower rates on the initial income bands.
Non-residents taxed at higher of 15% flat or resident rates without reliefs
The flat 15% rate applies to all employment income for non-residents. Progressive rates without reliefs would also come to about 15% in this range, so both yield similar results.

Maximise your reliefs each year by contributing to SRS ($15,300 relief), making CPF Medisave top-ups, and claiming all eligible family reliefs — the effective tax savings can significantly exceed the cost of contribution.
