The South African Red Cross Air Mercy Service Trust, a registered welfare organisation and VAT vendor, provided aero-medical services to various provincial health departments under written contracts. These services included air ambulance, rescue, and medical transfer services, for which the Trust received payments calculated according to agreed tariffs. The Trust applied for a binding VAT ruling contending that the payments received from provincial governments were zero-rated under s 11(2)(n) of the Value Added Tax Act 89 of 1991, on the basis that they constituted a deemed supply of services under s 8(5). The Commissioner for SARS ruled that the services were actual supplies subject to VAT at the standard rate. The High Court found in favour of the Trust, declaring the payments zero-rated. SARS appealed to the Supreme Court of Appeal.
