Many Australians have already lodged their 2025–2026 tax return. For some, the process is finished. For others, additional information may arrive later, records may turn up, or they may realise something was missed when the return was lodged.

If you've already lodged, don't assume it's too late to fix a mistake. Tax returns can generally be amended if information was omitted, an error was made, or new information comes to light after lodgment.

You might receive an income statement, dividend statement or interest summary you hadn't seen before, find records you thought were lost, or notice that something in your return doesn't match your own records.

If you lodged the return yourself and have concerns about something you've discovered, it may be worth seeking advice before deciding whether any action is needed. If your tax professional lodged the return, let them know as soon as possible so any necessary corrections can be considered.

The ATO generally recommends waiting until your original return has been processed before requesting an amendment.
