Business income can cover anything from selling goods online to investing overseas to running a large company. How your income is taxed depends on what kind of income it is.
There are specific rules about withholding taxes, including schedular payments. You may also get income that is not from business, for example salary and wages, individualised funding or foreign superannuation.
