I need to make an international bank transfer into an overseas account one similar to PayPal. The bank is however asking me for my tax number before proceeding, I understand one can take up to R1 million per annum offshore and therefore by asking for the tax number it falls under a purchase/discretionary allowance and not a gift because I am transferring to my own account similar to PayPal. My question is will I be taxed on the purchase if I give my tax number? There is also an option to pay visa credit card but I prefer the international bank transfer as its cheaper in fee's? Thoughts?
