One banking mystery has been cleared up by yesterday's data dump by the Australian Taxation Office.The data shows that the revenue, profit and tax paid of PayPal Australia in 2013-14 were A$255 million, $12 million and $3.6 million, respectively.In its financial report for 2014 lodged with ASIC, PayPal presented a different picture for its Australian arm. In that document PayPal reported revenue of $291 million and a net profit of $2.2 million, much less than disclosed to the ATO.
