Important information 2023

Provides important information and instructions to complete and lodge your tax return.

Last updated 24 May 2023

Who can complete your tax return?

You can get someone else to complete your tax return for you:

  • A family member or friend can help you but they cannot charge you a fee.
  • Tax Help is a free service provided by community volunteers trained to help people earning around $60,000 or less prepare their tax returns. Tax Help volunteers do not charge a fee for their assistance. Tax Help volunteers can help you online, by phone or in person at a Tax Help centre. To make an appointment, see Tax Help program.
  • Only a registered tax agent can charge you a fee for preparing your tax return. To check whether an agent is registered, refer to Finding and using a tax practitionerExternal Link.

Whoever helps you:

  • you, no one else, must sign your tax return
  • you, no one else, are legally responsible for the accuracy of the information.

Lodge your tax return by 31 October 2023

If you’re lodging your own tax return, you need to lodge it by 31 October each year.

If you choose to use the services of a registered tax agent, they will generally have special lodgment schedules and can lodge returns for clients later than 31 October. If you are using a registered tax agent, you need to engage them before 31 October.

If you're having difficulties meeting your tax obligations or are unable to lodge by 31 October, contact us as soon as possible.

Failure to lodge on time penalty

We may apply a penalty for failure to lodge on time if your tax return is not lodged by the due date.

Generally, we apply one penalty unit for every 28 days (or part thereof) that your tax return is overdue, to a maximum of 5 penalty units. For more information regarding penalty units refer to Failure to lodge on time penalty.

We may apply the penalty even where there is no tax payable. However, our policy is not to apply a penalty where:

  • you lodge your tax return voluntarily, and
  • no tax is payable.

Your right to make a complaint

Where you believe we have not met your expectations or not conducted ourselves as outlined in the Taxpayers' Charter, we support your right to make a complaint. We are committed to treating complaints seriously, dealing with them quickly, fairly and learning from them. Making a complaint will not affect your relationship with us.

If you disagree with a technical decision we have made about your tax affairs, you have the right to have the decision reviewed through the formal process. Refer to Dispute or object to an ATO decision.

Check our potential resolutions information for issues we can help with before deciding to lodge a complaint.

If you're still concerned about an issue, you can:

  • discuss it with an ATO officer who will aim to resolve your issue – see Enquiries
  • try to sort it out with the tax officer you've been dealing with or phone the number you've been given
  • talk to that officer's manager if you're not satisfied
  • consider making a formal complaint if you're still not satisfied.

How to make a complaint

To make a complaint:

If you have previously lodged a complaint and you are not satisfied with the way it is being handled, or with the outcome, you may request for your complaint to be escalated to a more senior officer. To escalate your complaint, contact ATO Complaints on one of the methods listed above.
