When to lodge your tax return
Your tax return is due by 31 October each year.
Tax returns cover the financial year, not the calendar year. The financial year begins on 1 July and ends on 30 June the following year. After the financial year ends, you have until 31 October to lodge your return (unless you use a tax agent).
For example, you should have lodged your tax return for the financial year 1 July 2014 - 30 June 2015 by 31 October 2015.
If you use a registered tax agent to prepare your tax return, you can usually lodge later than 31 October. See your registered tax agent before 31 October to qualify for their lodgment dates.
If you can’t lodge on time
If you can't lodge your tax return by 31 October, or by your registered tax agent's lodgment date, you can ask the ATO for an extension. You should not lodge your tax return if it is incomplete.
