When does the 90-day rule start?On 1 December 2026. From then, a claim must be made within 90 days of the day the support was delivered.
Does it apply to supports delivered before 1 December?The NDIA has not yet confirmed this. The safe approach is to claim anything older before 1 December, then claim each support within 90 days.
What if I miss the 90 days?A claim made after the window may not be paid. Treat 90 days as a hard limit and claim well inside it.
Do I need to keep records?Yes. From 27 August 2026 providers must keep records relating to NDIS claims for 7 years.
