expenses or losses of a capital nature,
less:

cost of computer hardware and software,
cost of patents ... etc.,
cost of manufacturing plant or machinery,
depreciation allowance of plant and machinery ,

tax loss brought forward ,
and the balance (if positive) is Assessable Profit.
Tax payable = Assessable Profit * Tax rate

If the balance is negative, it is called tax loss which is to be carried forward to set-off the next year's assessable profits.
