All income earned in or derived from Singapore is chargeable to income tax.
Generally, overseas income received in Singapore on or after 1 Jan 2004 is not taxable, except in some circumstances.
Income earned may come from different sources such as:
Tax Treatment of Employee Remuneration
Income Received in the Form of Government Grants:
These Government grants are taxable in the Year of Assessment when the payouts are received. Only Wage Credit Payout will be auto-included in the tax return for self-employed taxpayers.
Generally, cash gifts received by an employee or a self-employed individual are considered part of his income if the gifts accrue to him by virtue of his office or for services rendered.
In this respect, if a person is exercising an employment or carrying out a vocation as a religious practitioner and receives cash gifts from the members of congregation or devotees, the gifts constitute income received by him for services rendered and are taxable.
