  • Service fees
  • Transportation fees

Tax is calculated at the standard personal income tax progressive rates – 0% to 37%.

A deduction from the taxable income for expenses can be either the actual expense incurred, for which supporting documentation must be presented to support the tax return filed, or a standard rate as a percentage of income. The standard allowable rate varies between 0% and 85% depending on the type of income.

Personal allowances such as those for a spouse, children or the purchase of an LTF or RMF can also be deducted from the taxable income when calculating the tax payable.

Income earned on certain types of income will be received by the individual net of withholding tax. The withheld amount is credited back when calculating the tax liability.

It is important to note that taxable income is recognised on a cash basis.
