WHO NEEDS TO REGISTER FOR VAT?

Persons who make taxable supplies in excess of R1 million (from 1 March 2009) in any 12-month consecutive period are liable for compulsory VAT registration, but a person may also choose to register voluntarily provided that the minimum threshold of R50 000 (from 1 March 2010) has been exceeded in the past 12-month period.
