In terms of the South African Value Added Tax Act all prices advertised must include VAT at the applicable rate (normally 14%). Any price submitted in an advertisement is thus assumed to include VAT.
Advertisements submitted with prices which specifically EXCLUDE VAT will have 14% added before the advertisement is displayed.
Advertisements for Zero-VAT-Rated items and VAT-exempt goods will be published as-is.
It remains the seller’s responsibility, however, to confirm that the price quoted includes or excludes VAT, and any other charges and taxes applicable.
