Tax return filling requirements for non resident with SA bank interest income?

Tim, I am (i) a foreign national (ii) non-resident in SA for tax purposes (physical presence test) and (iii) will likely spend more than 183 days in SA in the tax year 2015/16. My only SA source income is interest income from a bank, which is unlikely to exceed R40-50. 000. Do I need to register with SARS and file an income tax return for the tax year 2015/16 under those circumstances?

You do not need to register or submit a return because even though you are taxed on your SA income the total amount is below the tax thresholds.
