Thanks for the responses guys. Yes the funds are my own and it's money that i have been saving. So if i understand this correctly then it's as follows. If hyperthetically, I deposit funds into a fixed deposit account for 2 years and the interest i earn would be say R40000 per year, the first R23800 is excempt and i only get taxed on the remaining R16200. This R16200 is then added to my annual income and then taxed? Am i taxed annually or only after the maturity date of the fixed deposit which is 2 years?
