The end of the financial year is coming in quick, but shockingly one-in-four Aussies don’t complete a tax return each year. This could mean millions of Aussies are missing out on a $1080 tax bonus that is only available by lodging your tax return this year. When it comes to lodging tax returns, 19 per cent of Gen Z are not completing a tax return each year because they don’t understand the tax system, showed the research, while forgetting to do it was also a major reason. Just over half of Aussies admit their knowledge of the end of financial year and tax return is minimal in the survey of almost 1500 Aussies. Yet there are key things to do to get organised for lodging a tax return, according to Mark Chapman, director of Tax Communications at H&R Block.
