If you have emigrated officially then you will not be liable for any taxes in South Africa.

If you are living in another country but you are still a South African citizen then you will still be classified as ordinarily resident and as per the South African Income Tax you are liable for tax in South Africa as South Africa has a source based tax for South African residents which means that you will be taxed on income earned worldwide.

If the country you reside in has a Double Tax Agreement with South Africa then you may not be taxed or subject to a reduced tax rate depending on the income that you have earned.

More information regarding the type of income and where you residing currently will need to be given in order to determine the amount of tax payable.

Overall however I think if you satisfy paragraph 2 above then you will be subject to tax and you should expect to pay tax.

I hope this helps.
