If you're registered for GST and lodge quarterly, your Business Activity Statement is usually due on:
- 28 October (July-September)
- 28 February (October-December)
- 28 April (January-March)
- 28 July (April-June)
Tax agents often get later dates. Your calendar in Aussie Biz Registrations shows these as reminders.
