I have a very technical question

The company I work for is part of an international group, HQ in Amsterdam, our SA company basiccaly does the labour for the HQ.

One of our Salesmen (Dutchman, employed by the SA company) received commission on sales that he did for the HQ company, this commission income was paid into his forgein bank account in euros by the our HQ company.

Is there any PAYE payable on this commission, my director advised me that there is no taxes payable by the salesmen because he is a temporary SA resident and for the 1st 5 years all his forgein income isn't taxable in SA, is this so?
