Foreign Earned Income

Hi, I am wondering about the tax I pay, if any, if I am earning my income overseas. In my case I earn in Indonesia, and the money gets deposited into an Indonesian account. I would like to send my money back to South Africa though. I would only be in South Africa for 1 to 2 months of the year. What tax would I have to pay, if any?

Your foreign earned income would be exempt from tax.

Can I claim a portion of my foreign income as exempt?
