Thanks kincella, and to all who have provided suggestions. Have taken the first step and sought professional advice - and will be happy to share on this forum my experiences.
First of all - costs will be around $300 to create trust + $200 in stamp duty.
Trust will have a number of natural person beneficiaries + the option to add a corporate beneficiary at any stage (for another $800 or so). I am happy to accept the compliance obligations personally, such as filing ASIC returns etc. This will allow the streaming of income into a regime where tax can be effectively deffered within a 30% environment almost indefinetly (until dividends are paid).
Whilst the generation of $150k per annum (the point at which it become more tax effective to earn income in a compnay rather than as a natural person) is not likely for some time, there are still some benefits to having a compnay in the strucutre. I will seek further advice from tax specialist but its seems possible to stream capital gains to the natural person on a 0% marginal tax rate whilst streaming revenue type income to the corporation. This would make the capital gains tax rate zero.
Now heres a question - when are the proceeds of the sale of shares held for less than 12 months deemed to be income and not capital gains?? Is there a rule of thumb that should be applied?
