This includes taxable interest earned, rental income and any other monthly income that you have received, other than the amount inserted under 'Monthly Salary' above.
An example of a deduction would be an expense that you had to produce the OTHER MONTHLY INCOME like rental income. For example, if you have received R15 000 in rental income but you had expenses of R1000 to produce this income. The R1 000 would qualify as a deduction.
This is the total of all proceeds from the disposal of all capital assets less the base costs, any exclusions, losses and the annual exclusion (currently R40 000) and multiplied by the inclusion rate of 40%.
