Ninety-four per cent of taxpayers in Tasmania have already lodged so far this year, followed by South Australia at 85 per cent.
Western Australia sits at a close third at 83 per cent, followed by the Northern Territory at 82 per cent.
Victoria has come in fifth so far this year, with 81 per cent of taxpayers having lodged, and Queensland is at sixth with 78 per cent.
At the bottom of the list so far this year, with less than a week to go until 31 October, are ACT and NSW, at 75 per cent and 72 per cent respectively.
The ATO expects to see the traditional lodgement spike as the 31 October deadline for self-lodgers approaches. Often, this is where the tax office finds a spike in lodgement errors.
“Over eight million Australian residents have already lodged their returns this tax time, but we know some people are leaving their run pretty late,” said assistant commissioner Kath Anderson.
The ATO has warned taxpayers and tax professionals about several items on its watch list this year in relation to income tax compliance, especially popular work related work-related expenses.
Work-related car expense claims were flagged as a hotspot for the ATO in late August, after the ATO found that for the 2015/16 financial year, around three million Australians made claims totalling over $8 billion.
The ATO found that a “significant portion” of those claims were right at the limit of requiring detailed records, which has raised alarm bells.
