Am I liable for SA tax?

I am British, have my family and home in South Africa, work abroad for long periods of time and don't work in SA. Sometimes I take a long holiday at home - three or four months. I sign a contract for each company I work for abroad. Am I liable for SA income tax?

How long are you away for each time? How long have you been in SA?

These are the number of days I was in South Africa, including travel days (flying out or landing):

2015: 154 4 2 = 160 days
2014: 10 7 15 3 = 35 days
2013: 23 146 14 = 183 days

I received my Permanent Residence permit on 9 December 2013.

I have paid full income tax in UK up to beginning of April 2014.

No you will not be liable for SA income tax for any of the income earned whilst you are outside SA.
