How much I will get as tax refund?

I came to South Africa on June 30,2015. My income is R4,35,000 / year. I am aware of that the tax year is Mar 2015 to Feb 2016. So, I am not here from Mar 2015 to June 2015. Still do I need to pay tax? If how much I need t pay? How much I will get tax refund?

Currently, the tax amount is being debited from my monthly salary from employer and the amount is around R8000. Could you please let me know how much I will get tax refund?

You will only be able to submit a tax return next year for this period where you will get some of your taxes paid back.
