Why is GST included on only some of my invoices?

GST is always included on the platform fee invoice from mobility, reflecting a service transaction between mobility and you, regardless of your GST registration. For client invoices, GST is shown only if you, as an independent support worker, are registered for GST. However, services funded by NDIS budgets or Support at Home are GST-exempt, so invoices for these services won’t include GST, even if you’re registered.
