Purveyors South Africa Mine Services (Pty) Ltd (Purveyors) entered into a dry lease agreement on 12 January 2015 with Freeport Minerals Corporation (Freeport), a US tax resident, to operate an aircraft for air charter services in the Democratic Republic of Congo (DRC). The aircraft was kept at O R Tambo International Airport when not in use. Purveyors commenced provision of air charter services on 19 January 2015 to Tenke Fungurume Mining SARL (Tenke), a non-resident mining company in the DRC. On 16 November 2016, Purveyors' share ownership changed from Freeport to CMOC DRC Limited (Hong Kong incorporated). On 30 January 2017, Purveyors contacted SARS via email seeking to "regularize the VAT that was supposed to be paid over," having received a technical opinion from PwC that import VAT should have been paid. SARS official Mr Du Preez responded on 1 February 2017 advising that the aircraft was subject to penalty implications. In subsequent correspondence through March 2017, Mr Du Preez explained that VAT and penalties were payable, with no waiver of penalties. Purveyors acknowledged its understanding of these liabilities. Despite warnings from SARS and confirmation from PwC that VAT, penalties, and interest were due, Purveyors took no further action until 4 April 2018, when it submitted a Voluntary Disclosure Relief Application under section 226 of the Tax Administration Act 28 of 2011 (TAA). SARS rejected the application on grounds it was not voluntary under section 227 of the TAA, as SARS already had knowledge of the default and had prompted Purveyors to comply. The Tax Court upheld SARS' rejection, and Purveyors appealed to the Supreme Court of Appeal with leave.
