question tax for non resident, page-14

Off the top of my head, I see your situation as this:

You are a non- res of Aust. I assume you are certain of that, so therefore taken as given. Non-resident rates therefore apply.

You would appear to be a "trader" as opposed to an investor. Therefore profits from trading will be taxed as ordinary income and CGT rules not applicable.

As a general rule, you will be subject to tax on trading income in the source country (ie Aust). Hence you will need to lodge an Aust tax return. It is possible (but unlikely) that the tax treaty (if one exists) between
your country of residence and Aust may give taxing rights to your country of residence.

As a non-resident you are not entitled to imputation credits attaching to franked divds.

Also, companies are required to withhold tax on the unfranked part of a dividend paid to a non-res at the rate of 15% (depending on tax treaty). Technically you should notify registries of your status as a non-resident although probably not practical given the rate at which you trade.

That will be $500 thanks........
