Points to Note When Using Tax Calculator
The tax payable figure produced by the Tax Calculator is for your information only. Its correctness always depends on whether you have entered the correct income figure, deductions, your marital status and the number of your dependants. The Inland Revenue Department accepts no liability whatsoever for any loss or damage which may be incurred by its use.
The Tax Calculator can indicate whether it is to your advantage to elect joint assessment if the income and deductions of you and your spouse (where applicable) are inputted in the input page.
If you and/or your spouse had income chargeable to property tax and/or profits tax, the Tax Calculator can indicate whether it is to your advantage to elect for personal assessment. Please input the total income and deductions of you and your spouse (where applicable) in the input page.
