Purlish Holdings (Pty) Ltd paid substantial provisional income tax to SARS and later submitted corporate income tax returns for the 2011–2014 years of assessment declaring no income or expenditure, describing itself as dormant and ‘never traded’. It also failed to register for VAT or submit VAT returns for relevant periods. On the basis of the ‘nil returns’, the appellant sought a refund of the provisional tax paid. SARS conducted audits and discovered that Purlish had in fact concluded consultancy agreements and earned substantial income during the relevant years, and that its fees were VAT-inclusive. SARS issued additional assessments for corporate income tax and VAT, levied interest, and imposed understatement penalties at 100% on the basis of gross negligence. On objection, SARS reduced the penalties to 25% (income tax) and 50% (VAT). The appellant appealed to the Tax Court, which dismissed the appeal and increased the penalties back to 100%. Purlish then appealed to the Supreme Court of Appeal.
