What if I enter the wrong information?
If you catch your mistake before you submit your return, you can go back to the relevant section and correct the mistake yourself. If you discover an error soon after submitting your return, promptly leave us a note under the “Contact Us” tab of your status page. Hopefully, we will be able to correct the mistake before your return is lodged. If not, you may have to request an amendment of your return from the ATO.
