If an expat individual salary processed in feb will the tax deducted for entire year or only feb

If I have landed in South Africa on 20th of Jan 2016 and my salary for Feb 2016 is processed in South Africa. The tax would be deducted only for the month of Feb or for entire financial year that includes previous months wherein I was not part of SA.

It should only be deducted for the month of February.
