Yes. The rules are the same as for any other person, partnership or company.

That is.

• Compulsory if VATable turnover exceeds R1m
• Voluntary if Vatable turnover or purchases average at least R4 200 per month

Here’s what the VAT Act has to say about it.

s51.   Bodies of persons, corporate or unincorporate (other than companies).—(1)  Subject to the provisions of section 46, where any body of persons, whether corporate or unincorporate (other than a company), carries on or is to carry on any enterprise—

(a) such body shall be deemed to carry on such enterprise as a person separate from the members of such body;

(b) registration of that body as a vendor shall be effected separately from any registration of any of its members in respect of any other enterprise.
