income tax as calculated has to be paid before the due date of filling return

If you are a sole trader, you must lodge a tax return on the normal tax form for individuals.
Tax will be payable on the profit (income minus expenses) you have made from your sole trader activities, together with any other income earned, such as wages and salary income, interest, dividends, ect.


Sole traders are treated no differently for tax purposes than individual salary and income earners. However, if you make a profit from your sole trading activities, the Australian Taxation Office (ATO) will ask you to pay an estimate of the tax you will be liable for in the following year, on a quarterly basis. This will be done on what is called an Installment Activity Summary.
