Can a minor's taxable income affect a parent's taxable income?

My son is a model and his only 5 years old I submitted his tax return I registered him with SARS E-Filing, however I did not load myself as his representative which means telephonically they can not assist me however what I want to know is when loading myself as his representative at my nearest branch, would my tax returns at any point be linked to his or will it run separately?

As his parent, you are responsible for registering for him for tax and submitting tax returns on his behalf. However, your tax return is separate from his and your affairs won't be linked in anyway.

Thank you Tim

Only a pleasure!
