The POCT is a tax on NET Wagering Revenue and in your gaming example would be applied to the 15% aat the rate of 10%, not added to the 85% which is a legislated obligation. Further 70%+ of the wagering operators in Australia have stated publicly they will not pass the tax on at a cost to them of net wagering revenue from racing of say (0.5-0.55%) which may mean less bonus bets or marketing or sponsorship to preserve the exiting margin. Also a bookie, if it could pass it on in full as per your example, faces a situation where many punters have multiple accounts, thus it would either increase its risk of loss (and reduce its revenue) or if it won on all occasions, increase its Net Wagering Revenue thus increasing the tax to be paid. Finally, the smaller bookmakers in terms of turnover (who are not taken over in the ongoing market consolidation) will benefit from the tax being levied only above a threshold level e.g. $0.5 or $1 million. The tax is being brought in to ensure all the benefits of on-line gambling by bookmakers is not passed to the government of the NT(where they pay minimal tax). None of the benefits of the NT tax flow to the wider racing industry whereas in several of the States the racing industry will benefit from all or part of the tax being passed to it. Also, the latest official statistics on total wagering turnover in Australia indicates in the year 2015/16 it increased by 3.5, on-line gambling is the fastest growing segment and not being taxed has eroded the states’ revenue base. It would seem that the real issue is whether the loss of bonus bets, marketing and sponsorship will be greater than the increase the racing industry gets from the flow-on of the tax where governments take this action.
