SARS calculates import VAT at 15% on the Added Tax Value (ATV). For imports from outside the Customs Union, ATV generally includes your customs (CIF) value plus 10% of that value, plus customs duty; goods originating in Botswana, Lesotho, Namibia, or Eswatini follow different ATV rules (see Duties and Taxes for Importers). Use the calculator for your estimated landed total, then add a local price you have seen (usually VAT-inclusive) to see which side looks cheaper on paper — before delivery time and returns.
