There are several kinds of reporting that can be requried for tax purposes. 

Many business taxes (where not-for-profits are required to pay these - this will depend on your circumstances) can be completed on a form called an activity statement. Activity statements can be used to report and pay 'pay as you go' (PAYG) instalments and withholding, fringe benefits tax (FBT) instalments, goods and services tax (GST) and related tax obligations.
