Provisional Tax vs Personal Tax?

I've recently started working for myself. I've registered a business (which will start trading in 2016) but have been working through my own bank account (for the last 6 months) on the side (~ R6000/m) while getting preparations complete. I registered myself as a provisional tax payer, and I want to know if I can de-register myself for personal tax? Do I just submit a blank personal tax sheet since I filled in a provisional one for myself?

You can deregister by going to your SARS eFiling profile and clicking the Tax Types tab and deselecting the Provisional Tax box. However you can never de-register for personal tax, this is always a requirement. The business you are running will no doubt pay you a salary which you will have to pay personal tax on a submit a tax return to SARS.
