Can I get a UK CGT credit against SA CGT?

If I am resident in SA but sell a UK property I will have to pay UK CGT, but as this isn't income tax, will I get a credit for the UK CGT paid against the SA income tax due on the gain?

Yes you will be able to claim the tax credit against any taxes paid. Using the TaxTim system we will ask you all the correct questions under the foreign CGT section.
