First attempt to have your concern addressed by your ATO or TPB contact, or their manager.

We encourage you to raise your concerns with the ATO or TPB officer that you have been dealing with, or their manager. They may be able to assist you in resolving your concerns directly and at the earliest possible opportunity.

If you remain unsatisfied, you should lodge a formal complaint with the ATO or TPB for review.

Lodge a formal complaint with the TPB

Tips for lodging a complaint with the ATO or TPB

• Be sure to clearly explain your concern and the outcome you want to achieve
• The ATO or TPB should contact you and provide you with a complaint reference number (e.g., the ATO’s complaint reference format is 1-XXXXXXXXXXX). If you do not hear from them within a couple of weeks, you should contact them and follow up.
• Be prepared that the ATO or TPB may ask for further information to help assess your complaint.
• If you are not satisfied with the outcome of your complaint or the way its been handled, you should discuss this with the agency.

If you remain unsatisfied, you can lodge a tax dispute with us under Step 3

If you continue to remain unsatisfied, you may lodge a taxation dispute with us for independent investigation. If you have not completed step 2, we will redirect your complaint to the relevant agency (ATO or TPB) for formal complaint review unless we consider that there are special reasons why we should conduct an investigation in the first instance.

We strongly encourage you to lodge your dispute via our Secure Portal – especially if your matter is urgent. Lodging your dispute online is the quickest way to raise your concerns with the IGTO, and you will receive an immediate confirmation that we have received it.
