Just had an interesting thought. What if I ran my business entirely on bitcoin? Would I be exempt from company tax? According to the ATO https://www.ato.gov.au/General/Gen/...rrencies-in-Australia---specifically-bitcoin/ It at first seemed promising: but then: Then they will nab you for FBT: Bummer. But of course that only applies if you told them, just like the cash business economy.
usually you need some kind of gateway that depends on a fiat transfer, therefore any significant activity (over $10k per year) you will need to tell them.
