Australia’s biggest business taxpayers paid more than $57.2 billion to the ATO last financial year, with the latest snapshot on corporate transparency showing an estimated shortfall of 4.3 per cent.

That $2.6 billion tax gap shortfall – the difference between the amount of tax collected and what would be paid if every taxpayer fully complied with the law – was significantly lower than similar estimates for small businesses ($12.5 billion) and individuals ($8.4 billion).
