Ann: Phase Two Wet Plant Erection Stage Commences-NSL.AX, page-86

Depends on the capital gain size.... Ie a capital gain of 50k, if owned for more than 12 months, comes down by 50% to 25k...

Then the 25k is based on the marginal tax rates table... See below link

https://www.ato.gov.au/rates/individual-income-tax-rates/

In this case, first 18.2k is tax free, remainder is taxed at 19% plus Medicare potentially...

Plenty of people do it through partners, kids etc..

In general they need to be over 18...

But considerations need to be given to means and asset testing items also, like youth allowance, pensions etc... Don't want to stuff them up...

Everyone is different so naturally, see your tax man
