What if a due date falls on a weekend or public holiday?

The ATO generally allows lodgement/payment on the next business day. Always check your specific obligations.

Can I import these dates into Outlook or Google Calendar?

This feature is coming soon—stay tuned!

Does the tool update for changes in ATO rules?

Yes, updates will be reflected as soon as ATO or state authorities publish new compliance dates.

Who needs to lodge a BAS?

All GST-registered businesses must lodge Business Activity Statements quarterly, monthly, or annually depending on turnover.

Do super payments need to be received or just sent by deadline?

Payments must be received by the employee’s super fund no later than the deadline; sending is not sufficient.
