Commission Tax implications?

I work on commission only. Is my tax automatically paid by my employer? And do I have to submit a tax return? What are the consequences if I don't?

Your PAYE should be paid automatically however because of the changing nature of your commission earnings it may be that too much or too little PAYE was deducted. You are also able to claim all your business related expenses which you incurred in earning that income. Register for TaxTim and answer our questions in order to be able to complete your return.
