If you are a sole prop yes. A company needs a business account in the name of the business. Payments are done to the name of business.In your case it goes to your personal income because it is in your name which is not allowed.
Sars said the same,so i dont want trouble with sars when they might audit me and red flags go off. They are quite strict about this when i asked them.But hey you can do whatever,it's mzansi right...anything goes.
