  • Pre-filling your online tax return

    When you lodge online with myTax, we pre-fill your tax return with information we already have. You can also upload your records from the myDeductions tool to pre-fill your tax return in myTax. Pre-filling can make doing your tax return easier and more accurate.

    How we get information for pre-fill

    Pre-fill information comes from:

    • organisations such as employers, banks, health funds and government agencies
    • records you have uploaded on the ATO app's myDeductions tool
    • our record of your previous tax returns and current tax account status.

    How much information we can pre-fill depends on when we receive the information from those organisations and when you lodge your return.

    Information is usually available to be pre-filled into your return within a couple of days of it being reported to us.

    Organisations who report to us must provide information by certain dates, for example:

    • employers must provide us with details of payment summaries by 14 August
    • banks, credit unions and share registries must send us information about your investments by 31 October.

    Most information is sent to us by mid-August but many organisations send us their information much earlier.

    You can use the Pre-fill availability page to check if we've received information from the organisations from which you receive income.

    You can also start your myTax returnThis link opens in a new window to see what pre-fill information is ready.

    Before you finalise your return

    Always check any pre-filled information against your own records. You should correct the pre-filled information if you have more up-to-date information.

    If you believe the pre-fill information is wrong, contact the organisation that provided the information to resolve any differences before lodging your return.

    For example, if we pre-fill $24 interest from your bank but your own records show you only received $12, query this with your bank – it's possible they recorded your account in one name, when it's actually a joint account.

    If there is an error in the organisation's records, they must send us the corrected information.

    If we identify data that doesn't match, we will seek clarification from you.

    If you need the full account details to query a pre-fill amount with an organisation, you can phone us on 13 28 61.
