The NDIS 90-day claim rule: how to avoid missing a claim

From 1 December 2026, the time you have to claim an NDIS support after it's delivered drops from 2 years to 90 days. That's a real change in how much slack there is - a support that's paid for and forgotten for a couple of months used to be fine; from December, it might not be claimable at all. Here's what's changing and how to make sure nothing slips past the deadline.

What's actually changing

Currently, participants and plan managers have up to 2 years to submit a claim for a support delivered under a plan. From 1 December 2026, that window shrinks to 90 days from the date the support was delivered - not from when the invoice arrives, and not from when you get around to processing it. If 90 days pass without the claim being submitted, it risks not being payable at all.

This sits alongside the new record-keeping rules that started 27 August 2026 (see our full breakdown) - so a support delivered today starts two clocks at once: a retention clock measured in years, and a claim clock measured in weeks.

Who this actually hits

It matters most for self-managed participants, who submit their own claims through the myplace portal and don't have anyone else checking the clock for them. It also affects plan managers claiming on a participant's behalf - a backlog of unprocessed invoices is now a genuine risk, not just an inconvenience. Agency-managed participants are largely unaffected, since the NDIA pays providers directly and there's no claim step for the participant to manage.

Why claims go missing in the first place

It's rarely one big mistake - it's usually a few small ones stacking up. An invoice lands in a personal inbox and gets buried under everything else. A participant is using several providers who each invoice differently, on different schedules, and one just gets missed. Or a claim gets half-prepared and then forgotten because there was no reminder pulling it back into view. None of that was a real problem when the window was 2 years. At 90 days, it is.

How to keep the clock from beating you

The fix is starting the clock the moment the support happens, not whenever the paperwork is dealt with - and having something track the countdown for you instead of relying on memory. That's what Juste's claim reminders do for self-managed participants: the moment an invoice lands (however it arrives - photo, provider auto-feed, or added manually), the 90-day clock starts, with reminders at day 5, 14, 30, 60 and a final alert at day 80, plus a traffic-light view of what's still outstanding and a one-tap shortcut to the myplace portal to actually lodge it.
