Cigarette packet take off = +- 33%.
It might not be applicable but be warned though, SA income tax system will change very soon and there will be no such thing as a self determined non resident ex pat pilot. In effect, if you want to go offshore you will have to apply for financial exit. That will not be a problem to obtain but on the date that comes into effect all your world wide property, save only South African fixed property, will be assessed for CGT and you will have to pay the CGT. The likelihood is that you will have to sell assets to meet that bill.
These regulations can be found on SARS website and others too. They are specifically designed to counter South Africans who work in low tax jurisdictions and who, on the not too distant future, will be liable for full SA taxes.
