How to begin preparing and lodging your tax return using myTax.

Last updated 16 June 2024

Self-assessment

You are responsible for your tax return

Under the self-assessment system, you take responsibility for declaring all your income and for being able to support all your claims for deductions and tax offsets when you sign your tax return. This includes when you sign it using an electronic signature.

If we pre-fill your tax return with information provided to us by your employer or other organisations, you also take responsibility for the correctness of that information when you sign your tax return.

We will issue a notice of assessment to you, usually without adjustment. However, your return may still be subject to review.

If you become aware that your tax return is incorrect, you need to request an amendment by logging in to our online servicesExternal Link.

Will you be penalised if something is missing?

We routinely compare information between what you include in your tax return and the information provided to us by employers and other organisations. If we detect discrepancies or other errors after we have issued your notice of assessment, we will contact you and may issue an amended assessment. You will be obliged to repay any tax owing, and any interest and penalties we may impose.

If you make an honest mistake when following our information in myTax and you owe us money as a result, we will not charge you a penalty. However, you must pay the money owed, and we may also charge you interest. If correcting the mistake means we owe you money, we will pay it and any interest you are entitled to.

If you voluntarily disclose mistakes in your return, we will take that into consideration in deciding what interest and penalties to impose.

We will pre-fill your myTax return

What you need to do

We'll pre-fill your return with all the available information reported to us by organisations, such as:

  • banks
  • employers
  • government agencies, and
  • private health insurers.

This information is reported to us from 1 July, with most of it available by late July.

All you have to do is:

  • review the pre-filled information by checking it against your records
  • enter any other missing details to complete your tax return.

You must make sure all the information on your tax return is correct before you lodge it, including all the pre-filled information.

If you delete your pre-fill data, you can select to 'Restart' your tax return to see all of your pre-fill data. If you do this, you will lose any information that you have manually entered into your tax return.

Why you may want to wait until late July to lodge using myTax

Historically, most information is reported to us and available for pre-filling by late July. All of your information may be available before this, but sometimes it takes a little longer.

For example, you may find that:

  • some of your income statements and payment summaries have been pre-filled, but not all of them
  • your income statement is 'Not tax ready'
  • interest from one financial institution has been pre-filled but interest from another one hasn’t been.

You can complete myTax from 1 July if you prefer not to wait for all your information to be pre-filled. If you do, you will need all your records and statements to enter information yourself to complete and lodge your return.

What information can we pre-fill?

We will pre-fill for you all the information provided to us at the time you do your myTax return, including:

  • Australian Government allowances, pensions and payments
  • salary, wages, foreign employment income and other amounts that are shown on income statements or payment summaries
  • Australian superannuation income streams, annuity payments and lump sums
  • interest from financial institutions including ATO imposed interest
  • public company dividends including exploration credits
  • managed fund distributions
  • employee share scheme interests
  • business and personal services income amounts that are shown on an income statement or payment summary including
    • voluntary agreements
    • labour hire
    • other specified payments 
     
  • information reported on a Taxable payments annual report (TPAR), such as
    • payments and grants reported by government entities
    • payments reported by businesses providing
      • building and construction services
      • cleaning services
      • courier services
      • road freight services
      • information technology (IT) services
      • security, investigation or surveillance services
      • mixed services (a business that provides one or more of the services listed above) 
       
     
  • a reminder about possible capital gains tax events for
    • details of share disposals
    • transfers of property
    • crypto assets 
     
  • amounts received through a partnership distribution
  • a reminder you received interest or dividends from a foreign financial investment in previous income years
  • private health insurance policy details
  • spouse details, if you indicated you had a spouse on 30 June in the previous year's tax return
  • deductions that you have uploaded to your tax return via the myDeductions tool.

What if you don't agree with the pre-filled information?

If you have checked the pre-filled information against your own records or statements and it doesn't match, generally you can change or delete the pre-filled information in myTax.

If you do this, it is important to resolve any discrepancies with the third-party provider before you lodge. They may need to send new or amended information to us to ensure our records are accurate.

TPAR payments or grants

You will not be able to change or delete the TPAR pre-filled information.

If the pre-filled TPAR record does not belong to you, or you have entered the income in another section of your return, you can ignore the record.

To ignore a TPAR record and lodge your tax return:

  • When myTax requires you to select Type of income, select 'Other income'.
  • At Prepare your return, select Add/Edit at Other income.
  • At the Other income section, myTax will ask you to review your information at this section.
  • Enter any information you must include at this section (excluding the pre-filled payments and grants that don't belong to you).
  • When you are finished, select Save and continue.

The incorrect data will not be included in your tax return.
