Why is your BAS due date different from another business?
It can depend on whether you lodge monthly, quarterly or annually, whether you lodge it yourself or use a registered tax or BAS agent, and whether an extension or deferral applies.
Even a nil BAS may still need to be lodged, and extra time to pay does not automatically mean extra time to lodge.
Check the date shown on your statement or ask your accountant what applies to you.
