I'm working as a sole trader with an international band - they're touring Australia, i'm in charge of booking shows, invoicing venues and passing the net income to them at the end of the tour.
I understand that I have to withhold 30% tax for the ATO (assuming they don't get a variation).
Not sure how I remit this WHT to the ATO as a sole trader? is it possible to do it myself, or do I need a tax agent?
