I understand that the tax threshold in 2014 is 70700 Rand. In the financial year 2013/2014 I have earned only 55.000 Rand through freelance activities with different companies (I am a student). So my question is, will I have to try to bring the taxable income even more down (e.g. through claiming business expenses, medical expenses etc.) or do I need not bother as I am anyway below the threshold?
