I know that there is a tax benefit in certain countries for search funder investors, is there any sources of information that speak specifically to this in the South African context and generally explain this?

My best guess is that since the fund will have no income in the first two years but a bunch of expenses, the assessed loss can be carried over to the years after acquisition. this would mean that the benefit will likely only result in a benefit in the first year since the aim is to purchase a high-growth business with steady revenue.

Is there any other tax benefit that could be offered to investors as a value proposition to investing into a search fund rather than normal PE?
