  • myTax 2021 Tax estimate – important information

    Your tax estimate is based on the information in your tax return. This includes information:

    • you've provided
    • that's been pre-filled that you consider is correct.

    If you haven't completed all your information, myTax will still show you an estimate based on the information currently in your tax return.

    The myTax calculation is an estimate only and the final balance of your assessment may differ.

    When we have processed your return, we will send you a notice of assessment. In some cases we send a statement of account with a notice of assessment.

    Why your myTax estimate may differ from your final assessment

    The final balance of your assessment may differ from the myTax estimate when:

    • it involves complex calculations – for example, income averaging
    • we receive information that affects the balance of your assessment.

    This includes situations where you:

    • have a credit or debit balance with the ATO
    • have a debt with Services Australia or another Australian Government department
    • are lodging the return late
    • have incorrectly edited or deleted pre-filled information
    • received an employment termination payment
    • received an Australian superannuation lump sum payment
    • had excess concessional superannuation contributions
    • had excess non-concessional superannuation contributions
    • are entitled to use your spouse’s unused seniors and pensioners tax offset
    • have requested we calculate the deductible amount of your undeducted purchase price of a foreign pension or annuity
    • received credit for tax paid by a trustee
    • are entitled to a government super contribution
    • are entitled to a low income super tax offset
    • have amounts where rounding rules apply.

    After you've lodged

    Remember, you have until 31 October 2021 to lodge your 2021 tax return with myTax, unless we have allowed you to lodge it later.

    If we work out you:

    • are entitled to a tax refund – we will pay it to the Australian financial institution account you've nominated at Step 2 Financial institution details.
    • have a tax bill to pay
      • if you lodge on time, any tax bill will be due the later of
        • 21 November 2021 (21 days after your tax return was due to be lodged), or
        • 21 days after you receive your notice of assessment.
         
      • if you lodge late, any tax bill will be due 21 November 2021 (21 days after the tax return was due to be lodged).
      • your notice of assessment will contain your payment advice. However, when your account balance is different to the outcome of your assessment, we send a statement of account and attach the payment advice to it.
      • you can make payment towards your tax bill after you have lodged your tax return. See How to pay for your options.
