there is no 50% cgt tax

there is a 50% discount on cgt for individuals if you hold a stock longer then 12 months.

if you don't - you add it to your assessable income and get taxed at your Marginal rate.

only benefit of being an Individual is the 50% cgt discount
if you make dozens of trades must I recommend you tax plan and look at all the avenues

setting up a company purely for trading will be more beneficial as a base rate entity pays 27.5% tax if you make over $1m it will go to 30%

it really depends on your situation

this is not financial advice
