Lodging a Business Activity Statement
If you choose to complete your BAS statement form online, you can do so via the ATO’s Business Portal, your myGov account (if you’re a sole trader), or through SBR-enabled financial, accounting, or payroll software.
It is also possible to lodge by mailing your completed BAS statement form with the pre-addressed envelope included in your BAS package.
If you have got a registered BAS or tax agent, they can lodge or pay on your behalf. In this case, the agent will take all the responsibilities.
