The ATO says nil activity statements can be generated early in some cases. Under normal bulk processes, activity statements generally issue from the ATO by the end of the month.
However, the ATO says there may be a specific reason for a business to access its activity statements early, such as: if you are a short-term visitor (for example, you are an entertainer or sports person and will be leaving during the relevant period); or know that you will be travelling when an activity statement is due.
Tip: Activity statements can be generated for up to six months in advance.
