The New 90 Day Rule: What It Means for Your NDIS Invoices
From 1 December 2026, every NDIS support has to be claimed within 90 days of the day it was delivered. Until now the limit has been two years. It is one of the quieter changes in the new NDIS laws, but it touches every plan, however your funding is managed.
What is changing
The Securing the NDIS for Future Generations laws passed Parliament on 19 August 2026. The NDIA lists the claiming change under its December 2026 changes: claims must be submitted within 90 days of delivering a support. The clock starts on the date of the support. A provider sending an invoice late does not restart it. For example, a support worker shift on 2 December 2026 will need to be claimed by early March 2027.
It has already started, in a way
Since 15 October 2026, the NDIA has been doing extra checks on any claim lodged more than 90 days after a support. Those claims can be held for up to 28 days, and the NDIA may ask for more evidence before paying. Claims made within 90 days go through the usual process.
What if a claim is late?
The NDIS claims system will normally reject it. The law does allow a late claim to be accepted where exceptional circumstances caused the delay, and the claim was made within a reasonable time after that. What counts as exceptional has not been spelled out, so treat it as a safety net for real emergencies, not a plan.
Five things to do before 1 December
Clear the backlog: Gather any unpaid invoices or unclaimed receipts and get them claimed.
Ask providers to invoice promptly: Weekly or fortnightly is ideal. If you are plan managed, invoices can go straight to your Plan Manager if requested.
Pick a claiming day. If you self-manage, choose the same day each week to lodge claims.
Check your portal regularly. Look at what has been claimed in the myNDIS app or portal. Gaps are easier to fix early.
Keep your records. Participants will need to keep records of supports and payments for 3 years, nominees for 5 years and providers for 7 years.
