Do I need to register for GST as an NDIS provider?

The full answer

NDIS invoices are typically GST-free regardless of your registration status — the federal government funds NDIS supports which are GST-exempt supplies. So most NDIS providers don't benefit from GST registration (can't claim GST credits on expenses if you're not registered, but also don't collect GST on sales). If you provide non-NDIS services (private pay supports, allied health above NDIS rates), GST registration becomes relevant. If you're over $75K annual NDIS revenue, you must register for GST unless you qualify for the exemption. Talk to an accountant about whether voluntary registration makes sense for your mix of revenue.
