How do I turn my BIGO options into shares, page-17

Probably starting to verge on tax advice, so cannot go into much more detail. From what I understand, as an individual shareholder (not sharetrader) you caculate all your gains and losses over the year, if you have gains and have held all for over 12M you take those gains and divide by 2, this figure then is added to your assessable income which is taxed at your individual tax rate.
To tax capital gains at 30% you must be a company (or I think be classed as a sharetrader rather than shareholder. details on the ATO website for Australian residents for tax purposes, but then brokerage is treated differently as well) in both cases you are not entitled to the 50% discount for holding for more than 12m. All IMO and as you can see can get complicated very quickly so probably need to speak to an accountant before making investment decisions if you are in any way basing them on these discussions.
