The ATO classifies the amounts that it doesn’t count as assessable into three different categories: exempt income; non-assessable non-exempt income; and other amounts that are not taxable.
Exempt income
As the name may suggest, exempt income doesn’t have tax levied on it. The thing to remember here however is that certain exempt income may be taken into account for other adjustments or calculations — for example, when calculating the tax losses of earlier income years that you can deduct, and perhaps “adjusted taxable income” of your dependants.
Exempt income includes:
Non-assessable, non-exempt income
Non-assessable, non-exempt income is income you don't pay tax on and that also does not count towards other tax adjustments or calculations such as tax losses.
Non-assessable, non-exempt income includes:
Other amounts that are not taxable
Generally, you don't have to declare:
