If you choose to lodge your Tax Return by yourself, the due date for lodgement is 31 October 2021. By using a registered Tax Agent, you automatically get an extension until 15 May 2022. There are a few exceptions to this rule. If you have lodged late in the past, the ATO may give you an earlier lodgement due date.
Keep in mind, to receive an automatic extension with a Tax Agent you must engage them prior to 31 October 2021 in order for them to add you to their extension list.
What happens if I lodge late?
You may be liable for a Late Lodgement Penalty together with General Interest Charges. If you think you may miss the lodgement deadline, it is important you contact the ATO to request an extension or engage a Tax Agent to help.
