The appellant was a company operating two separate business units: a fuel service station and a transportation service consisting of 21 fuel tankers and trucks. It entered into two agreements with a third party fuel supplier: (1) a contract for transportation of fuel dated 1 March 2010, and (2) a memorandum of agreement for supply of petroleum products dated 10 March 2010. Between July 2010 and September 2013, the appellant purchased petroleum products worth US$9,000,409.19 from the third party and provided transportation services valued at US$7,339,989.38, of which US$6,206,785.09 was used to offset fuel purchases. The appellant voluntarily registered its transport business for VAT but only paid VAT on the net cash receipts of US$1,133,204.29, treating the US$6,206,785.09 used as offset as "payment in kind" rather than a taxable supply. Following a tax review, the respondent issued 29 amended VAT assessments totaling US$809,580.66 for the understated VAT. The appellant objected, arguing the transportation services constituted payment, not supply, but the objection was disallowed.
