Central Provident Fund (CPF)
If you make S$120,000 a year living in Singapore, you will be taxed S$22,350. That means that your net pay will be S$97,650 per year, or S$8,138 per month. Your average tax rate is 18.6% and your marginal tax rate is 15.0%. This marginal tax rate means that your immediate additional income will be taxed at this rate. For instance, an increase of S$100 in your salary will be taxed S$15, hence, your net pay will only increase by S$85.
A S$1,000 bonus will generate an extra S$850 of net incomes. A S$5,000 bonus will generate an extra S$4,250 of net incomes.
NOTE* Withholding is calculated based on the tables of Singapore, income tax. For simplification purposes some variables (such as marital status and others) have been assumed. Income tax calculations include personal tax credit deductions. CPF calculations are determined for regular wages only, assuming there are no additional wages.
