Every Tax Time, the ATO focuses on certain "hotspots" where taxpayers are prone – either accidentally or deliberately – to make errors. These are the areas it will concentrate its audit firepower on and for those who have made claims in areas which the ATO will be targeting, they can be a wake-up call both to ensure that you get it right this year and that you go back and check that you did it right last year.

It's tax time and that means first time filers have some questions about just how things works. Here are some answers to the most common questions people have.

Letters are being sent out to Australian taxpayers who have fallen foul of the ATO's data-matching system. Don't fret if you get one.

Receiving one of these letters doesn't mean that the taxman is coming to to destroy your existence - it just means that something doesn't line up with your tax return and you're being given a chance to fix it.

Each year, the Australian Tax Office sets its focus on particular areas they'll be honing in on as they review tax returns and where we're trying to reduce our taxes. This year is no different with cryptocurrency earnings, money made from new platforms like Uber, home office expenses and work-related claims on their hitlist.
