In 2011, the Zimbabwe Revenue Authority (respondent) conducted a tax investigation into HE Limited (appellant), a public company listed on the Zimbabwe Stock Exchange, covering 2009-2011. The investigation revealed that the appellant was cessionary to technical assistance agreements with a South African company providing skilled personnel and technical services, and had computer software licensing agreements with Australian and South African companies. The appellant paid license fees to foreign companies but failed to withhold non-residents tax for fees or remit them to the respondent for October 2010 to November 2011. The appellant also failed to withhold 10% of gross income payable to a parastatal offering transport services during July-December 2010 when the parastatal lacked a tax clearance certificate, breaching s 80(2) of the Income Tax Act. The appellant admitted liability for principal amounts and paid during investigations but disputed penalties and interest on penalties. Under the technical assistance agreement, fees were payable monthly based on 2% of gross turnover, to be calculated from management accounts, confirmed by audit certificate, and then remitted. The appellant compiled management accounts between the 13th-15th of each month following service provision, but the audit certificate for April 2009-March 2011 was only issued on 16 December 2011. Fees were paid in December 2011 and March 2012, but withholding tax was paid on 13 May 2011, predating both the audit certificate and fee payments.
